As a consequence, it is soft, with little internal rigidity. 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. Wick Feed Lubrication System - China Manufacturers, Factory, Suppliers. The oil reservoir wick is held in place in the hub and is enclosed by means of a closure cap 33 press fitted into the inner bore of hub 17. 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. 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. The scoop lifts the oil upward and . Leather Sewing Machines . Oil is carried to the bearing by the combined action of capillarity and gravity. In this vedio we study about lubrication and thaeir types . 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. 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. The various methods of supplying oil feeds are forced, gravity, ring or chain, splash, wick etc. Dual wick lubrication system saturated with gear oil for extended gear life over 700 hours. Gravity Feed i. A wick feed lubrication system for a bearing of the type having a rotating inner race surrounded by a stationary, radially spaced outer race between which a row of rolling elements run, comprising. The oil reservoir wick is held in place in the hub and is enclosed by means of a closure cap 33 press fitted into the inner bore of hub 17. Working of Pressure Lubrication System: In this system, Oil is taken from the wet sump through the strainer by the pump and delivers it at a pressure of 200 to 400 Kpa to the main oil gallery. Wick oilers are used in applications where precise oiling is required. 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. Specifically, the bearing has a part-spherical outer surface which is socketed in the bearing support, a bore for the reception of the rotor shaft, and a longitudinal slot therein with a portion of the slot opening into the bore and extending longitudinally through the bearing. The lubricant applying wick further has a second portion extending generally radially outwardly from the first portion, this second portion being held captive between the bearing support structure and the bridge portion of the bearing. 1. Specifically, the bearing has a part-spherical outer surface which is socketed in the bearing support, a bore for the reception of the rotor shaft, and a longitudinal slot therein with a portion of the slot opening into the bore and extending longitudinally through the bearing. Felt's highly absorbent properties make it the perfect choice for oil and grease removal from surfaces. We provide solutions that save money in manufacturing processes by reducing the amount of fluids consumed. 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. 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). 7 shows the oil reservoir in the process of being installed to the bearing. UNSPSC 27131511. In this manner, both the radial and thrust surfaces (i.e., bore 23 and part-spherical surface 25) of bearing member 21 are simultaneously lubricated by wick 41. Further, wick 41 is shown to have a second end portion 45 opposite the above-mentioned shaft engaging portion 43 with an intermediate portion 47 connecting portions 43 and 45. Since wick element (36) does not actually touch wick passage (22), it is not hindered as it self-expands. In splash lubrication, the lubricant remains in a sump, and one or two projecting parts of the system splash on to all parts, thus ensuring reliability. 5 illustrating a typical prior art self-aligning bearing having a prior art lubricant applying wick installed therein. 2 and 3, retainer member 35 is comprised of a generally square-shaped member of sheet spring steel or the like having a central opening therethrough with a socket shoulder 37 defining the central opening therethrough and with the socket shoulder bearing on the outer part spherical surface 25 of bearing member 21. 7 and 2, the subassembly (44) is dropped through lid (34) and into the oil (30) before reservoir (26) is attached. 7 is a view similar to FIG. Owner name: 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. 3 through 5, a wick element is indicated generally at (36). 3 /sec and should be reserved for low speeds and light duty.

Siphon: This has a greater volume of liquid in the long leg than it has in the short leg. As a consequence, it is soft, with little internal rigidity. Other objects and features of this invention will be in part apparent and in part pointed out hereinafter. 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. As shown in FIG. FIG. Wicks are color coded to coordinate wick speeds with application need. Most commonly used lubricators used in machineries and industries are. A dumb bell-shaped felt piece with a narrower center section and enlarged ends is surrounded by a closely fitting, compressed coil spring that gives rigidity to the felt piece, and which keeps the enlarged ends spread apart .
