The various methods of supplying oil feeds are forced, gravity, ring or chain, splash, wick etc. Leather Sewing Machines . 3 is a vertical cross sectional view taken along line 3--3 of FIG. Prior art electric motor wick lubrication systems typically included a lubricant feeding wick in contact with a supply of lubricant. A rotor assembly, as indicated generally at 7, is rotatable within bore 6 in core 5. Mist lubrication system is that, in which the lubrication of a bearing is done by the oil in the form of oil mist. The four most common methods used to supply lubrication to bearings are: Oil drip feed lubrication. Corresponding reference characters indicate corresponding parts throughout the several view of the drawings. 3. Conventional lubrication methods. 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. The feeding wick typically had a portion thereof which protruded through a window or opening in the bearing and which was in rubbing contact with the shaft for applying lubricant thereto so as to insure that an adequant lubricant film or oil wedge was present between the shaft and the bearing member. Wick Feed Lubricator: Figure 8.7 show the assembled drawing of wick feed lubricator. 3. Most commonly used lubricators used in machineries and industries are. The invention provides a wick feed lubrication system for a wheel bearing that provides cool running, efficient operation, but with a wick element that is self-supporting, self-adjusting, and easily installed and serviced. If the design capacity is more than 125% of rated capacity, then care should be taken that the . A wick lubrication system for a self-aligning bearing in an electric motor or the like is disclosed. Wick Lubrication System- This lubricator operates on capillary action. Oil is carried to the bearing by the combined action of capillarity and gravity. Linear guiding device with rail race lubricating elements. Significant savings in repair and spare costs. b) wick feed lubricator system. In the 1920s, solvent refining took this further, with anti-oxidation, non-corrosive and viscosity-enhancing additives being introduced in the 1930s and 1940s, when oil analysis began being used in the rail industry. Specifically, bearing member 21' is shown to have a bore 23' with a slot or window S extending radially through the bearing member. Check the pressure level in a lubrication system: Step 1. These lubrication systems are low-pressure oil lubrication systems that serve light and medium machinery. 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. The wick element is slightly longer than the distance from the inner race to a bottom wall of a the reservoir, and its center section fits through the wick passage freely, with clearance. Two axially spaced rows of bearing balls run between the races. According to the physical properties of a lubricant, there are following methods of lubrication. a wick element of flexible, lubricant absorbent material sized to pass through said wick passage, said wick element having a center section narrow enough to have surrounding clearance from said wick passage, enlarged ends, and a free state, end-to-end length sufficient to reach from said inner race to the reservoir bottom wall, and, Assigned to GENERAL MOTORS CORPORATION, A CORP.

Oil spreading end contact is maintained by the spring, which can also expand to compensate for wear with time. Designed to lubricate individual machines or complete plants, automatic lubrication systems provide proper, precise lubricant replenishment to all required points, enabling a range of benefits in the process. Oil can be introduced to the bearing in many ways, such as drip-feed, wick-feed, pressurized circulating systems, oil bath or air-oil mist. a) Oil can Lubricator : This is the direct application of oil to a moving machine Air-Powered Drum Pumps with Hose andFilter/Lubricator for Water, Oil, Coolants, and Chemicals. 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. Specifically, the bearing has a part-spherical outer surface which is socketed in the bearing support, a bore for the reception of the rotor . FIG. As a consequence, it is soft, with little internal rigidity. As the elevator operates, the hoist ropes are cleaned. 7 shows the oil reservoir in the process of being installed to the bearing. 2. 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. 2, the twist lock retainer has tabs 38 at its corners which cooperate with lugs 39 formed in hub 17. 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. FIG. 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. 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. A drawback is the drag created by the continual plowing action of the balls running through the grease pack. 3 /sec and should be reserved for low speeds and light duty. Another type of lubrication system is the splash 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. 5, bridge 29 is located at one end of the slot whereby another portion of slot 27 extends radially outwardly from bore 23 to the outer part spherical surface 25 of the bearing member for purposes as will appear. 2. Different methods are used to apply lubricants to machinery. The wick is a soft, oil absorbent material capable of capillary action. The oil pressure ranges from 100 to 250 psi. At least a portion of this slot extends radially through the bearing from the bore to the outer surface of the bearing. 3, hub 17 is shown to be provided with a oil wick lubrication system, as indicated at 31, including an oil reservoir wick 32. EMERSON ELECTRIC CO., 8100 WEST FLORISSANT AVE., S, Free format text: a) drop feed lubricator system. Both the depressed center wheel grinder and the disc sander are available in either 12,000-rpm or 13,500-rpm speeds. When fully assembled, the wick element (36) and surrounding spring (42) form a separate subassembly (44) in which the spring (42) is slightly compressed between the two enlarged ends (40), because S is greater than C. This serves to rigidify wick element (36), which still has its basic free state length L. Spring (42) has an additional function, described next. Each oiler includes a multi-pack of colors for flow testing. Oftentimes, as shown in FIG. 3 shows the wick element and spring prior to assembly; FIG. Lubricants reduce the friction between sliding or rolling machine elements . Referring now to the drawings and particularly to FIG. Tool Weight 1.7 lb. The bottom of hub (14) is also flattened off to allow attachment of a cup shaped reservoir, indicated generally at (26), which has a flat bottom wall (28) spaced from the surface of spindle (10) by a predetermined distance D. Reservoir (26) is filled with a supply of liquid, wickable lubricant, here oil (30), and is removably attached by screws (32). Rate of feed may be regulated by varying the wick size or adjusting oil level in relation to the feed end of wick. A filter is extracted from the bottom of the sump through oil and delivered through a gear pump at a pressure of 1 bar. 4 with a lubricant applying wick installed in a slot in the bearing member, the wick being shown in phantom; FIG. 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. . This lubrication level is about 20% of the full oil-feed rate of 5.6 in. Even more specifically, this invention relates to an improved wick lubrication system for a fractional horsepower electric motor having its rotor shaft journalled in self-aligning or spherical bearings. 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. Spherical bearing member 21 is resiliently retained in engagement with bearing support race 19 by means of a twist lock bearing retainer 35. 4. While the bearing illustrated in FIG.
