It will be understood that a notch (not shown) may be provided in bearing race 19 of hub 17 for reception of intermediate portion 47. As is best shown in FIGS. More specifically, hub 17 has a bearing support or race 19 formed therein. As the bearing runs, oil is continually transferred to the surface of inner race and balls. 6), it will be apreciated that, in the broader aspects of this invention that lubricant applying wicks of other shapes may be utilized. 5. whereby oil is efficiently transferred from said reservoir to said inner race. Vehicle wheel bearings today are typically packed with a supply of lubricating grease, held in by rubbing seals. Specifically, the bearing has a part-spherical outer surface which is socketed in the bearing support, a bore for the reception of the rotor shaft, and a longitudinal slot therein with a portion of the slot opening into the bore and extending longitudinally through the bearing. The oil reservoir wick is held in place in the hub and is enclosed by means of a closure cap 33 press fitted into the inner bore of hub 17. Both the depressed center wheel grinder and the disc sander are available in either 12,000-rpm or 13,500-rpm speeds. Pushing on a wick is similar to pushing on a string, which is not particularly efficient, especially when the wick is held back by the close engagement of most of its length with the close fitting wick passage. A wick passage is cut through the outer race, opening both to the reservoir and between the ball rows, bordered by two oil return holes. 7 is a view similar to FIG. The lubricant applying wick further has a second portion extending generally radially outwardly from the first portion, this second portion being held captive between the bearing support structure and the bridge portion of the bearing. Corresponding reference characters indicate corresponding parts throughout the several view of the drawings. b) wick feed lubricator system. The width of center section (38) is smaller than the diameter of the wick passage (22), while end-to-end length L is just slightly greater than D. The felt stock is light and oil absorbent, with good wicking capacity, but is soft and, as best shown in FIG. 7-66. This helps administer the right amount and keep the gear oil on the metal gears. .

Flow rate depends on temperature.. Use 90 elbow cups for side-mount applications and where vertical space is limited.. Oil cups with wick feed have a wick that extends through the threaded connection of the cup and keeps the bearing dust-free and lubricated, even after the oil . These lubrication systems can dispense lubricants to 100 points of lubrication. Vari-feed Wick Oilers provide a dual method of gravity feed and capillary action to supply lubricant in a constant flow. Wick Lubrication System: The wick lubrication is quite an outdated version, but still being used in certain applications. 1; FIG. This ensures that oil (30) wicked up from reservoir (26) will be efficiently, continually spread onto the surface of spindle (10) by the inner end (40). Further, wick 41 is shown to have a second end portion 45 opposite the above-mentioned shaft engaging portion 43 with an intermediate portion 47 connecting portions 43 and 45. 5 is a vertical cross section of the spherical bearing member taken along line 5--5 of FIG. 5), as indicated by dimension L. In FIG. Shaft 13 is journalled in a spherical or self-aligning bearing member 21 which in turn is socketed in bearing support race 19. Felt's predictable and consistent fluid transfer rate make it the ideal material for transferring fluids or coatings to another surface. Different methods are used to apply lubricants to machinery. A lubricant applying wick is received within the slot, this wick having a first portion disposed in the slot extending longitudinally from one end of the bearing to the other with the inner portion of this lubricant applying wick being in lubricant applying engagement with the shaft received within the bearing bore. Mist lubrication system is that, in which the lubrication of a bearing is done by the oil in the form of oil mist. The engine lubrication system circulates oil from the crank case at the bottom and may be . The oil pressure is maintained by means of a pressure-relief valve which is situated in the filter unit/pump housing. Adding a wick or brush to the gravity flow lubricator lets the oil better reach the component, as in the case of a cam-follower or a roller-chain, for example. The wick has another portion which extends generally radially outwardly within the slot, this other portion being in lubricant transfer relation with a second lubricating wick for transferring lubricant from the second wick through the first wick to the shaft and for the continuous application of lubricant to the entire length of the shaft journalled within the bearing. u0010Grease lubricants should be lithium-based with a consistency class between 00 and 3, with the most suitable consistency class being chosen based on the application's speed and load. Another method is to attach a sec- Consistency class, as defined by the National Lubricating . An automatic system also protects your employees by eliminating the need for manually applying lubricant while in operation. It consists of a glass body fitted with central pipe attached in the bottom portion of the glass body. 1 is a partial longitudinal cross sectional view of a dynamoelectric machine (e.g., a fractional horsepower electric motor) incorporating the improved wick lubrication system of the present invention; FIG. Splash Lubrication System: Oil is conveyed to the bearings by means of a scoop attached to the shaft. Oil Mist Lubrication Working Principle. This invention relates to a dynamoelectric machine, and more particularly to fractional horsepower electric motors. The most common systems are: The oil after lubrication is returned to reservoir either directly or through filters. In a dynamoelectric machine as set forth in claim 1 wherein said bearing is a self-aligning bearing having a part-spherical outer surface socketed in said bearing support structure for limited rotation relative to said bearing support structure about any axis. Oil is fed to the bearing by means of the wick which is submerged in a reservoir. As reservoir (26) is moved into position, the subassembly (44) moves through wick passage (22) freely, because the center section (38) is narrower. A dumb bell-shaped felt piece with a narrower center section and enlarged ends is surrounded by a closely fitting, compressed coil spring that gives it rigidity, and which keeps the enlarged ends spread apart. Typically, the motor includes a rotor shaft, a bearing support and a self-aligning bearing supported thereby journalling the rotor shaft of the motor. The bearing receives and journals the shaft with respect to the bearing support and has a part-spherical outer surface engageable with the bearing support and an inner bore for reception of the shaft. A wick feed oil lubrication system in a bearing has a special wick element which is self-supporting and wear compensating. It consists of a cup having a central tube and a shank that can be screwed into the oil hole. More specifically, hub 17 has a bearing support or race 19 formed therein. 1, 2 and 6, a vehicle wheel bearing includes an inner race or spindle (10). Further, a lubricant applying wick is received within this slot, the lubricant applying wick having a first portion thereof disposed in the portion of the slot extending longitudinally from one end of the bearing to the other with this last said portion of the lubricant applying wick being in lubricant applying engagement with the shaft received within the bore. Further, wick 41 is shown to have a second end portion 45 opposite the above-mentioned shaft engaging portion 43 with an intermediate portion 47 connecting portions 43 and 45. Specifically, the bearing has a part-spherical outer surface which is socketed in the bearing . Lubrication also avoids the moving parts not to come in direct contact with each other. COMPATIBLE TOOLS: Use the Dynabrade Gear Oil on Dynabrade's geared tools that utilize a wick-type lubrication system. Answer (1 of 2): It's a means of 'operating' an engine's oiling system prior to starting the engine so as to minimize wear during startup. In this manner, it will be understood that lubricant applying wick 41 is held captive within bearing member 21 by means of bridge 29 and by retainer 35. Frequent lubrication helps prevent premature gear failure and helps . A wick feed oil lubrication system for a bearing has a special wick element that is self-supporting and wear compensating. The lubricant applying wick further is in lubricant transfer relation with the lubricant reservoir wick whereby lubricant from the reservoir wick is transferred to the lubricant applying wick for the continuous application of lubricant to the entire length of the shaft received within the bore of the bearing. Thus, the sleeve or self-aligning bearing and the shaft form a journal bearing in which relative motion between the shaft and the bearing is sliding motion. The scoop lifts the oil upward and . Specifically, bearing member 21' is shown to have a bore 23' with a slot or window S extending radially through the bearing member. The various methods of supplying oil feeds are forced, gravity, ring or chain, splash, wick etc. Check that the sump tanks are ready for operation. 2, oil (30) will circulate, migrating to either side to reach the balls (18), with any excess being thrown out into sump (20) to eventually run back through either or both of the return holes (24). Oil is easier to keep clean for recirculating systems. Such a twist lock retainer is more fully disclosed in the coassigned U.S. patent, now U.S. Pat. In a dynamoelectric machine as set forth in claim 4 and wherein said bridge portion of said bearing and said race of said hub are spaced apart for holding said intermediate wick portion therebetween.

Turn off the circulating pump. Typically, the oil is pumped through an . . Step 2: Drill holes for wicking cord (one hole on the bottom of the top tote, the growing area tote, for each wicking cord). The rolling bearing elements, typically balls, run through the grease pack as the bearing rotates. As shown in FIGS. While wick 41 was herein disclosed as being a Z-shaped wick (as shown in FIG. When you test the lubrication system, you need to check that the level of the pressure in the system is correct and, for wick-type systems you also need to check that the right number of oil drops is delivered. 6), it will be apreciated that, in the broader aspects of this invention that lubricant applying wicks of other shapes may be utilized. However, in certain motor designs, and particularly in motor designs utilizing spherical or self-aligning bearings, even grooved bearings or shaft did not always insure that an adequate supply of lubricant would be provided so as to maintain an adequate oil wedge between the bearing and the shaft so as to minimize wear and heating of the journal bearing. 6 is a side elevational view of the lubricant applying wick; and. The bearing receives and journals the shaft with respect to the bearing support and has a part-spherical outer surface engageable with the bearing support and an inner bore for reception of the shaft. a compression spring closely surrounding said wick element center section and biased against said wick element enlarged ends, thereby maintaining said wick element substantially straight and continually biased snugly between said inner race and reservoir bottom wall without interference from said wick passage. Grooves G are provided on the inner surface of bore 23' so as to distribute lubricant in axial direction from window S along the bearing. 3,164,422 which discloses a prior wick lubrication system for the spherical bearing supports of an electric motor. Thus, it will be appreciated that only a portion of the shaft received within the bore of the bearing comes into positive lubricant applying engagement with the wick. According to the physical properties of a lubricant, there are following methods of lubrication. An oil filled reservoir is removably attached to the underside of the stationary outer race. Benefits. Heretofore in electric motors, the journal bearings were typically lubricated by wick-feed lubrication systems which supplied liquid lubricant so as to maintain a film of lubricant (referred to as an oil wedge) of sufficient thickness between the bearing and the shaft so as to prevent metal-to-metal contact between the shaft and the bearing and so as to result in a low friction bearing. Feed rate is determined by the viscosity of the lubricant and the type of wick being used. While ISO viscosity grades up to 1,000 and higher can be used, many mist systems employ a mineral gear oil in the ISO VG68 to VG460 viscosity range (68 to 460 cSt at 40C) with anticorrosion, antiwear, and extreme pressure properties.. Past problems with wax and additive separation from . As shown in FIG. Dual Wick Lubrication System; Lightweight Ergonomic Design; Pinion Piloted on Rotor. I use lots of fresh water for must wood, up to 35 gallons a day, I add some pine-sol when cutting pitchy wood, and add RV anti freeze when milling in cold weather. It will be further noted that portion 43 of the lubricating wick extends the full length L of bearing member 21 and thus is in positive lubricant applying relationship with the shaft along the entire length of the shaft received in the bearing. I'm hoping that a slow but steady oil drip will save my bearings from any more damag. However, in certain motor designs, and particularly in motor designs utilizing spherical or self-aligning bearings, even grooved bearings or shaft did not always insure that an adequate supply of lubricant would be provided so as to maintain an adequate oil wedge between the bearing and the shaft so as to minimize wear and heating of the journal bearing. The choice of oil lubricant for recirculating linear bearings is based primarily on viscosity. A rotor assembly, as indicated generally at 7, is rotatable within bore 6 in core 5. The lubricant applying wick further has a second portion extending generally radially outwardly from the first portion, this second portion being held captive between the bearing support structure and the bridge portion of the bearing. Typically, the motor includes a rotor shaft, a bearing support and a self-aligning bearing supported thereby journalling the rotor shaft of the motor. Circulating systems keep bearings lubricated at all times. Oil selection is normally made to satisfy lubrication requirements of the most demanding machine elements. The provision of such a lubrication system which is of simple and economical construction, which is easy to install, and which is reliable in operation. I blow out the lube system at the end of the day. Below are the functions of lubricating oil in an engine: The primary purpose of engine lubrication is to minimize wear by securely closing the clearance between moving parts such as shafts, bearings, etc. 3 illustrating the end of a spherical, self-aligning bearing member; FIG. The one shown in Fig. Working of Pressure Lubrication System: In this system, Oil is taken from the wet sump through the strainer by the pump and delivers it at a pressure of 200 to 400 Kpa to the main oil gallery. Each oiler includes a multi-pack of colors for flow testing. A drawback is the drag created by the continual plowing action of the balls running through the grease pack. Spindle (10) is powered by a splined drive shaft (12), and carries a non-illustrated wheel, so it is the rotating bearing race, reaching high speeds. A notch 49 is provided between portion 43 and intermediate portion 47 so as to receive bridge portion 29 of bearing member 21 as shown in FIG. 3. 1, a dynamoelectric machine (e.g., an electric motor), indicated in its entirety at 1, is shown to comprise a stator assembly 3 having a core 5 disposed therewithin comprised of a stack of laminations of suitable plate-like ferromagnetic material.

Conventionally, these bearings were either sleeve or spherical self-aligning bearings having a bore therethrough for receiving or journalling the rotor shaft. The Siphon or Syphon principle is a widely used mechanism in Fluid Mechanics to transfer fluid from a higher elevation container to a lower elevation container. 2 is a left end view of the electric motor shown in FIG. 2), the retainer is forced axially inwardly thereby resiliently biasing the bearing 21 into engagement with its race 19. Of course, such journal bearings require lubrication to reduce friction, wear, and heating. 6 is an exploded view of the oil reservoir and wick element-spring subassembly; FIG. 1. Corresponding reference characters indicate corresponding parts throughout the several view of the drawings. Gravity Feed i. . Check that the shut-off valves at the main pumps are open. Larger bearing ends are lubricated through a nozzle spray. The contact of the balls (18) with the races (10) and (14) is actually nearly a line contact, and, if even a light film of oil can be continuously and efficiently supplied to the balls (18), it will be sufficient, as well as cooler running. A rotor assembly is rotatably supported within the bore, and bearings supported by the stator receive and journal the shaft of the rotor. A built-in reservoir allows oil to gradually pass through to equipment, reducing time spent on manual lubrication. Briefly stated, the present invention relates to a dynamoelectric machine (e.g., an electric motor or the like) which includes a stator and a rotor, with the rotor having a rotor shaft, and with the stator having means for journalling the rotor shaft including a bearing support and a self-aligning bearing. Jump to content. Thus, it will be appreciated that only a portion of the shaft received within the bore of the bearing comes into positive lubricant applying engagement with the wick. 7 is a view similar to FIG.
