Such a twist lock retainer is more fully disclosed in the coassigned U.S. patent, now U.S. Pat. Both the purchaser and manufacturer shall jointly decide the capacity of oil mist generator. 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). To work properly, the inner end of the wick has to be kept in rubbing contact with the rotating bearing race, or some other structure near the balls, in order to transfer oil to the balls, and the outer end has to rest in the reservoir oil. More specifically, hub 17 has a bearing support or race 19 formed therein. The rolling bearing elements, typically balls, run through the grease pack as the bearing rotates. The wick is a soft, oil absorbent material capable of capillary action. Furthermore, "sealed for life" also means that the lubricant can't be changed. Another method is to attach a sec- . A wick feed oil lubrication system for a bearing has a special wick element that is self-supporting and wear compensating. 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. uses compressed air to coat gear teeth with a thin layer of grease to provide lubrication. 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. Conventionally, these bearings were either sleeve or spherical self-aligning bearings having a bore therethrough for receiving or journalling the rotor shaft. Circulating systems . 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. Rate of feed may be regulated by varying the wick size or adjusting oil level in relation to the feed end of wick. Tool Weight 1.7 lb. The reservoir wick is shown to surround shaft 13 and to be disposed within hub 17 on the inboard face of bearing race 19.
