Force feed i. Grease lubrication system. Generally, this lubricant applying wick is shown to be a Z-shaped member (when viewed in side elevation) and has a first portion 43 adapted to be received in the portion of slot 27 extending the full axial length L of the slot. Reference may be made to U.S. Pat. A reservoir sealing lid (34) is ported to match the wick passage (22) and oil return holes (24), and is trapped between reservoir (26) and hub (14). This lubrication level is about 20% of the full oil-feed rate of 5.6 in. Wick Feed Lubrication System - China Manufacturers, Factory, Suppliers. Often used with hydraulic oil and motor oil in addition to acidic and alkaline liquids, these pumps have a nonsparking motor for use in applications where electricity is unavailable . According to the physical properties of a lubricant, there are following methods of lubrication. Functions of Engine Lubricating System. Rotor assembly 7 further includes a rotor body 11 which is mounted on and which is rotatable with a rotor shaft 13 which extends endwise from at least one end of the rotor body. Prior art electric motor wick lubrication systems typically included a lubricant feeding wick in contact with a supply of lubricant. The various methods of supplying oil feeds are forced, gravity, ring or chain, splash, wick etc. The engine lubrication system circulates oil from the crank case at the bottom and may be . 1. 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). 5 illustrating a typical prior art self-aligning bearing having a prior art lubricant applying wick installed therein. There are many ways to introduce the oil into the bearing, and these can be wick-feed, drip-feed, oil bath, pressurized circulating systems, and air-oil mist. Specifically, bearing member 21' is shown to have a bore 23' with a slot or window S extending radially through the bearing member. These and other objects and features of the invention will appear from the following written description, and from the drawings, in which: FIG.

Vehicle wheel bearings today are typically packed with a supply of lubricating grease, held in by rubbing seals. From there, as shown by the arrows in FIG. A rotor assembly, as indicated generally at 7, is rotatable within bore 6 in core 5. 7 is a view similar to FIG. The scoop lifts the oil upward and . Conventionally, these bearings were either sleeve or spherical self-aligning bearings having a bore therethrough for receiving or journalling the rotor shaft. Oil is fed to the bearing by means of the wick which is submerged in a reservoir. Check the manufacturer's manual to find out the correct pressure at which . 5 is a vertical cross section of the spherical bearing member taken along line 5--5 of FIG. B. meter and distribute lubricant. Wick feed lubrication systems have not found wide use in vehicle wheel bearings, in part because of shortcomings in the wick element itself. 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. 6). 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. Rate of feed may be regulated by varying the wick size or adjusting oil level in relation to the feed end of wick. 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. Oil-mist lubricating systems should operate at pressures of ___ psi. 1. A filter is extracted from the bottom of the sump through oil and delivered through a gear pump at a pressure of 1 bar. by wicks, GENERAL MOTORS CORPORATION, A CORP.

Another method is to attach a sec- 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. Mist lubrication system is that, in which the lubrication of a bearing is done by the oil in the form of oil mist. 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. 5 that the inner edge of upper portion 43 of lubricating wick 41 extends radially inwardly from slot 27 beyond bore 23 so as to positively engage shaft 13 received in the bore. Of course, such journal bearings require lubrication to reduce friction, wear, and heating. As best shown in FIG.
