摘要:
A tension or idler roller for a belt drive system has an outer roller for engaging a belt, an inner support body adapted to be affixed to a machine, and a rolling bearing between the outer roller and the support body. The support body is comprised of a pair of identical cup-shaped elements oriented either with their open ends toward one another or their closed ends toward one another, the shells having an eccentric mounting. The inner ring of the bearing may be a separate element or it may be formed in the shells.

A clutch release bearing has a sliding sleeve of a vibration damping and noise insulating material. The sliding sleeve has a flange axially engaging a bearing outer ring, the outer ring being separated from a bearing inner ring by rolling elements. The sliding sleeve has a radially inner sliding surface with axially extending recesses, the recesses extending radially through the end faces of the sliding sleeve.

A method for making a bearing bushing for the support of the trunnion in universal joints comprising a cylindrical sleeve section, a bottom section at one axial end of the cylindrical sleeve section, the peripheral edge joining the sleeve section and bottom section being of small cross-sectional radius, consisting of the steps of shaping a blank to form the sleeve section and bottom section which uniformly extends axially inwardly to a central tip and thereafter flattening from the inside at least in the area of the central tip of the bottom section while supporting the bottom section and corresponding forging the outside surfaces of the bottom section in the area of the peripheral edge between the surface of the sleeve section and outside surface of the bottom section.
摘要:
A rolling bearing for lengthwise movement between a sliding element and a rail element has a cage arranged between the sliding element and the rail element, and at least one endless row of rolling bodies in the cage. The loaded rolling bodies of each row roll between longitudinal races of the slide element and the rail element, and the cage has longitudinal guides for loaded rolling bodies and unloaded rolling bodies, as well as turnaround guides for interconnecting the loaded and unloaded guides at each end. An elastic guide element is mounted on at least one side of one of the guide tracks to resiliently urge the rolling against the guide tracks.

In a method and apparatus for casting or molding cages for rolling elements, two slides are provided for each pocket. The slides have an engaging, inclined surface, and are shaped to permit one of the slides to be removed by initially sliding it along the inclined surface. The other slide may thereby be moved laterally in the formed pocket, and withdrawn from the pocket. Facing slides of adjacent pockets may be joined together, with limited movement possible therein, to form a complete ring serving as a mold member.

A clutch release device has a pressure plate mounted on a sliding sleeve, and a stationary ring of a bearing abut one side of the pressure plate. A clutch lever abuts the other side of the pressure plate, and is held from axial removal by a ring having a flexible outer rim. The holding ring is held to the pressure plate by a flange on the sliding sleeve. The clutch lever has a central aperture fitted over a central conical portion of the pressure plate, the aperture having a pair of inwardly directed projections. The outer diameter of the holding ring is greater than the distance between the facing ends of the projections.

A linear rolling bearing has an outer housing with a central bore. A plurality of radially inwardly directed axially extending projections in the bore form races for rolling elements under load, and surfaces between the projections serve as return races. A cage within the bore has a plurality of axially extending guide channels, and semicircular guide channels interconnect pairs of the guide channels to form endless channels for the rolling elements. The outer housing has inclined surfaces joining the corresponding races for loaded and unloaded rolling elements, whereby the inclined surfaces steplessly interconnect the respective races and extend radially outwardly from each of these races.

In a longitudinally movable rolling bearing having a plurality of endless rows of spherical rolling elements, elongated races are provided for supporting loaded rolling elements against the inner boring of a housing. The radially directed surfaces of the rails are identical, so that the rails may be reversed to prolong the life of the bearing. In one embodiment, the rails are straight in the lengthwise direction, for use in a bearing in a precision machine. In another embodiment of the invention, the rails are convex curved in the lengthwise direction, for use in a bearing requiring compensation for misalignment of a shaft and the housing.
摘要:
A clutch release structure includes a clutch release bearing having a running portion, or the like, positioned to axially engage the diaphragm or dish-shaped clutch release elements. The bearing portion, or the like, has an axially extending portion which projects through the central boring in the clutch release elements, and damping means are provided radially between this extension and the clutch release spring elements.
