摘要： The motor has a thrust cap fitted to its end cap by snap fit fingers. The thrust cap closes a hole in the bearing retainer of the end cap and provides a thrust bearing surface against which the end of the shaft contacts to limit axial movement or end play of the shaft. The thrust bearing surface is part of a metallic spring fixed to a body of the thrust cap.

摘要： The present invention relates to a thrust bushing formed in such a way as to maximize its lubrication during use to minimize its wear. Broadly, at least one surface of the bushing is formed with grooves that extend between its central aperture and its outer diameter to allow the free flow of lubricant between the two and thus lubricate the entire bushing surface of the thrust bushing as it rotates during steering. The grooves may take a variety of forms such as radially extending rectangular grooves or spiral grooves to better spread lubricant over the entire bushing surface. The bushings may be imposed directly between the axle and the lower yoke or may be packaged in a cartridge between a pair of discs to provide a self-contained, well-lubricated package.

摘要： A thrust bearing comprises at least one diamond bearing segment, wherein the segment has a front surface and a back surface. A plurality of bearing pads extend a predetermined distance from the front surface, each of the plurality of bearing pads has a load surface substantially parallel to the front surface. The plurality of bearing pads act cooperatively to provide a load bearing surface area. The bearing pads are shaped and arranged in a predetermined pattern to enhance the load carrying surface area, and the predetermined pattern creates a plurality of flow micro-channels between the bearing pads. In another aspect, a thrust bearing comprises a diamond bearing surface, and a predetermined pattern of cavities formed in the diamond bearing surface for providing a fluid reservoir for lubricating and cooling the load surface.

摘要： A locking device and its assemblage are provided for confining an object such as a shaft of a motor. The locking device is used to confine the shaft having an end with a recess portion having a defining surface to prevent the shaft from being displaced in an axial direction. The locking device is a geometrically closed-loop body having an opening, and having a flexibility so that the shaft will pass through the opening and the end of the shaft will thus be confined by the locking device while the force disappears. The locking device is free from contact with the recess portion of the shaft when the shaft is spinning. A simple process can be used to assemble and disassemble the locking assemblage.

摘要： Disclosed is a self-lubricating thrust bearing having a number of axially-aligned parts. The bearing is preferably in cartridge form and includes an internal circular spring. The spring is located between two adjacent disks and functions to force the disks apart when the bearing loading is below a predetermined amount. In this manner, when the bearing loading is low, the spring applies pressure to the bearing's components and any attached structure. When the bearing loading exceeds a predetermined amount, the spring becomes compressed sufficiently to enable direct contact between the disks while not interfering with the rotational movement of any part of the bearing.

摘要： A bearing, which may be used to mount a swing arm on the frame of a computer disk drive, has an outer race provided with two raceways of arcuate cross section. Each raceway has a row of raceway balls located along it. The raceway balls of each row, in turn, surround and bear against a separate pivot ball. The two pivot balls are greater in diameter than the circles described by the innermost areas of the rows of raceway balls, so that the pivot balls when urged together bear against the raceway balls of the two rows and urge them against their raceways. The force which urges the two pivot balls together may derive from spring-loaded arm engaged with one of the balls.

摘要： An aluminum thrust washer that has a wrought aluminum matrix that includes from 2 to 20 weight percent silicon, 0.1 to 4 weight percent of copper, with the remainder pure aluminum. The aluminum thrust washer is formed of a mono-metal structure without a backing layer. The wrought aluminum matrix has mechanical properties such that the aluminum matrix wears away, leaving silicon particles exposed at a thrust face of the washer, such that the density of silicon particles is continually increasing as the thrust washer is utilized.

摘要： This invention is an independent rotary supportive pad with the use of the nullFlat Bearingnull ring plate. The nullpadnull is constructed by having the nullFlat Bearingnull ring plate to be place between bi-planar surface. When the nullpadnull that is directly underneath heavy object such as television, computer monitor, stereo speaker, laptop computer or dining dishes. The pad replaces function of a television turntable or rotary table that acts, not only as a cushion between the planar surfaces of the base of the television to the planar surface of table or desk, but also allows revolving motion to take place with minimum increase in vertical height. In theory, the rotational supportive pad with nullFlat Bearingnull ring plate construction do not have a limit in width as long as the construction of the bearing plate follows the alternating rotational direction in each of the rings.
