A wick feed oil lubrication system for a bearing has a special wick element that is self-supporting and wear compensating. Lubrication (Oil) System $ 0.56 - $ 328.16. How do I make a Wick System? b) wick feed lubricator system. A needle valve adjusts the rate of flow, which may be seen as drops passing through the window beneath the glass reservoir. 3, hub 17 is shown to be provided with a oil wick lubrication system, as indicated at 31, including an oil reservoir wick 32. 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. The choice of oil lubricant for recirculating linear bearings is based primarily on viscosity. Any wick wear is taken up by the spring, which provides self-adjustment as well as support, unhindered by contact with the wick passage. Gravity Feed i. The recommended minimum temperature is typically at least 120F. 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. Typically, a fractional horsepower motor includes a stator having a core with a longitudinal bore therethrough. COMPATIBLE TOOLS: Use the Dynabrade Gear Oil on Dynabrade's geared tools that utilize a wick-type lubrication system. Turn off the circulating pump.

Oil can be strained, filtered, and cooled because it is . 3 illustrating the end of a spherical, self-aligning bearing member; FIG. 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. Referring now to the drawings and particularly to FIG. No. 4,219,245. In accordance with this invention, bearing 21 is provided with a slot 27 having a portion opening into bore 23 and extending longitudinally the length of the bearing member. The forced, the gravity and the wick feeds are more economical. Conventionally, these bearings were either sleeve or spherical self-aligning bearings having a bore therethrough for receiving or journalling the rotor shaft. c) ladder lubricator system. C. meter lubricant. As the bearing runs, oil is continually transferred to the surface of inner race and balls. 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. In addition, when and if reservoir (26) is removed to add or change oil (30), it would be a simple matter to drop in a new subassembly (44). Leather Sewing Machines . Jump to content. 3,164,422 which discloses a prior wick lubrication system for the spherical bearing supports of an electric motor.

Wick Oilers have a wick of loose textured, long fiber wool that supplies oil to the bearing through capillary action. . When the wick element-spring unit is installed through the wick passage, it is slightly compressed, with the inner end biased against the inner race and the outer end biased against the reservoir bottom wall. The working of this lubricator is based on the siphon principle. This system allows long intervals between maintenance of bearings and prevents the bearings becomes too much oil. 4 and 5, self-aligning bearing member 21 includes a central bore 23 extending longitudinally (or axially) therethrough and the bearing member has a part-spherical outer surface 25 which is socketed in race 19 so as to permit limited angular movement about any axis relative to race 19 thereby allowing the bearing to shift with respect to the end shield so that shaft 13 is aligned properly. Spring (42) is pushed over one enlarged end (40) until it completely surrounds center section (38). Corresponding reference characters indicate corresponding parts throughout the several view of the drawings. 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. No. 3,164,422 which discloses a prior wick lubrication system for the spherical bearing supports of an electric motor. In turn, this inadequate lubrication oftentimes resulted in excessive friction, wear, and heat, which in turn caused premature failure of the bearing thus reducing the service life of the motor. Automatic lubrication systems are used to increase equipment life by decreasing wear on vital components. Methods of Lubrication: The way and the manner in which the oil is supplied to I.C. The shaft surface speed in this case is 30 rev/sec 5 in. Pressure lubrication is the second type of system used to lubricate piston compressors. Tool Weight 1.3 lb. 2; FIG. 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. 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. 4, slot 27 has a width, as indicated by dimension W, and a length (shown in FIG. 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.
