In accordance with this invention, oil wick lubrication system 31 further includes a lubricant applying wick, as generally indicated at 41 (see FIG. 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. Benefits. They 'float' on a thin film of oil that is forced under pressure into . 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. Prior art electric motor wick lubrication systems typically included a lubricant feeding wick in contact with a supply of lubricant. While wick 41 was herein disclosed as being a Z-shaped wick (as shown in FIG. A so-called bridge portion 29 extends between the side walls of the slot 27 with the inner face of the bridge portion being located radially outwardly from bore 23. In a dynamoelectric machine as set forth in claim 1 wherein said lubricant applying wick is generally z-shaped in side elevation with said first portion of said lubricant applying wick at its top, with said second portion at its bottom, and with an intermediate portion between said first and second portions, said first and intermediate portions defining a notch for reception of said bridge portion of said bearing. 7-66. Gravity feed system: Oil holes, Oil cups, and wick feed lubricators. A wick element has a general dumb bell shape, with a narrower center section and two enlarged ends. 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. Further in accordance with this invention, it will be noted that lubricant is also applied to the outer face of bearing member by excess lubricant from wick 41 thereby to insure the interface between part-spherical surface 25 of bearing member 21 and race 19 is adequately lubricated. Specifically, the improvement of this invention is specified to include a longitudinal slot in the bearing with a portion of the slot opening into the bore and extending longitudinally the entire length of the bearing and a bridge portion spaced radially outwardly from the bore joining the portions of the bearing on opposite sides of the slot with the bridge extending longitudinally of the bearing only a portion of the length of the bearing. Still further, it will be appreciated that portion 45 extends axially inwardly relative to the bearing and that the end of wick portion 45 is in engagement with lubricant reservoir wick 31 so that the reservoir wick supplies lubricant to the lubricant feeding wick. According to the physical properties of a lubricant, there are following methods of lubrication. Methods of Lubrication. The recommended minimum temperature is typically at least 120F. 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. Oil is easier to keep clean for recirculating systems. Oil splash feed lubrication. 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 . Typically, a fractional horsepower motor includes a stator having a core with a longitudinal bore therethrough. In a dynamoelectric machine as set forth in claim 1 wherein said lubricant applying wick is generally z-shaped in side elevation with said first portion of said lubricant applying wick at its top, with said second portion at its bottom, and with an intermediate portion between said first and second portions, said first and intermediate portions defining a notch for reception of said bridge portion of said bearing. 1. 6-29), oil is splashed up from the oil pan or oil trays in the lower part of the crankcase. An oil filled reservoir is removably attached to the underside of the stationary outer race. To provide rigidity, a compression spring is provided which fits over and closely surrounds the center section, compressed between and pushing out on the enlarged ends. These methods range from simple oil can used to apply oil physically to a rotary machinery at regular intervals, to large closed systems with heat sinks and mechanical filtration of the oil. 5. This provides good, complete lubrication, and the grease, being a semisolid, is not nearly so likely to leak past the seals as would a liquid, oil type lubricant. Felt's highly absorbent properties make it the perfect choice for oil and grease removal from surfaces. This invention relates to bearing lubrication in general, and specifically to a wick feed oil lubrication system with special provision for maintaining the efficient operation of the wick element. Lubrication Systems. 1, 2 and 6, a vehicle wheel bearing includes an inner race or spindle (10). Leather Sewing Machines .

What is mist lubrication system? 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. As a machine, an operating wire rope must also have a lubri- . . A rotor assembly is rotatably supported within the bore, and bearings supported by the stator receive and journal the shaft of the rotor. suspension (16). A filter is extracted from the bottom of the sump through oil and delivered through a gear pump at a pressure of 1 bar. Another type of lubrication system is the splash lubrication system. Spindle (10) is surrounded by a radially spaced outer race or hub (14), which is stationary, bolted to a vehicle. Typically, the motor includes a rotor shaft, a bearing support and a self-aligning bearing supported thereby journalling the rotor shaft of the motor. Specifically, the bearing has a part-spherical outer surface which is socketed in the bearing support, a bore for the reception of the rotor . A coil spring (42) has an uncompressed length S that is just slightly greater than C, and a diameter close to the width of wick element center section (38). As shown in FIG. As a consequence, it is soft, with little internal rigidity. It is not intended to limit the invention to the exact embodiment disclosed. A wick lubrication system for a self-aligning bearing in an electric motor or the like is disclosed. As shown in FIG. Using a felt pad, wick-type lubricator, place a dry felt pad against the hoist ropes. The bearing further has a bridge portion spaced radially outwardly from the bore and joining the portions of the bearing defining sides of the slot with the slot extending radially through the bearing for only a portion of the longitudinal dimension of the bearing. Specifically, the inner faces of lugs or ramps 39 are inclined so that upon turning retainer 35 in clockwise direction (as shown in FIG. 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. Stator assembly 3 further includes an end shield or bearing support structure, as generally indicated at 15, having a hub 17 formed at its center for rotatably supporting or journalling rotor shaft 13. I blow out the lube system at the end of the day. Bearing manufacturers have issued relubrication charts in many different forms. Different methods are used to apply lubricants to machinery. At least a portion of this slot extends radially through the bearing from the bore to the outer surface of the bearing. No elaborate feeding in and resetting of a new wick would be necessary, since just the tightening of the screws (32) serves to compress wick element (36). 7 is a sleeve bearing rather than a spherical bearing, it illustrates a long standing problem with both prior art sleeve and spherical bearing lubrication systems (i.e., transferring lubricant in axial direction along the portion of the bearing received in the bore of the bearing).
