For adjustment of the relative positions of two machine parts, at least one of the machine parts is provided with projections outwardly formed by stamping, the projections having contact surfaces which lie against the other machine part. The adjustment is performed by setting the projections back under the influence of a pressing force according to requirements. By this operation a relatively large contact surface can be provided. The deformation process takes place exclusively in the transition region between the projection and the rest of the machine part. The restoring forces are relatively small and relatively constant over the entire restoring range.

A cage for ball bearings consists of two side rings connected together by webs, and having ball pockets with ball pockets having curved partial surfaces inside and outside of the pitch circle and displaced from one another in the axial direction. In this arrangement the rubbing between the walls of the cage pockets and the balls is very small and free space is provided for receiving a lubricant. The pocket walls of the cage sections lying in the region of one or the other of the side rings has several radially-overlying zones, with conical surfaces, the conical surfaces being arranged at different inclinations to the bearing axis.

In a hydraulically operable release arrangement for clutches, especially for vehicle clutches, the release force is transmitted to the plate spring or the like of the clutch by way of a piston, a fixed bearing ring, a multiplicity of rolling bodies, and a rotating bearing ring. The piston is movably arranged in a housing and is biased by a helical spring arranged in a pressure space formed between the piston and the housing. The piston and the housing are each provided with an axial projection. In order to secure the piston against rotation and to damp vibrations in the piston without additional machining or special parts, the helical spring is arranged with its spring ends abutting the axial projections such that rotation of the piston in the direction of rotation of the rotating bearing ring is prevented.

A hydraulic release arrangement, especially for vehicle clutches, consisting of a housing (1,2,3) with a pressure space (6) sealed by a rolling bellows (7), in which the release bearing (4) is arranged to be displaceable in the housing (1,2,3) in the axial direction.In order to produce a compact hydraulic release arrangement and inhibit the bending in of the rolling bellows (7) in the low pressure range, a spacing element (27) is provided in the space defined by the rolling bellows (7) between the release bearing (4) and the housing (1,2,3), the spacing element being arranged to abut the inside of the bellows wall with axial prestress with an annular projection in at least one turned-back region (30) of the rolling bellows (7).

A rolling bearing for lengthwise movement along a shaft comprised of an outer sleeve having a plurality of races therein for rolling bearings, a cage being provided to guide the rolling bearings. A sealing ring is provided at each end of the assembly, the sealing ring having lips extending radially inwardly to contact the shaft. The sealing lips are thin and elastically bendable, and are mounted to enable bowing thereof into free spaces on opposite sides thereof, depending upon direction of lengthwise movement of the shaft. As a consequence, for small movements of the shaft, the sealing lips cling to the shaft and become bulged, rather than sliding along the shaft.

A self centering clutch thrust bearing has a damping ring between one bearing ring and the sliding sleeve of a housing. The damping ring has resilient projections positioned to engage recesses in the housing with play, to damp small turning motions, and larger projections positioned to engage other recesses in the housing with play, to damp larger turning forces. The resilient projections are mounted to be operative in damping the forces prior to the larger projections.This invention relates to self centering clutch thrust bearings, and more in particular to the provision of damping means in such bearings.

A linear motion rolling bearing including an outer sleeve and a cage with loaded and return races defined therebetween and a plurality of roller elements in these races, has opposite end rings molded onto the outer sleeve and formed as a unitary structure with the outer sleeve including strips extending between and connected to the rings and extending axially along the bore of the outer sleeve, to maintain the end rings aligned and non-rotatable relative to the outer sleeve.

A rotary drill bit assembly comprising a drill bit body, at least one trunnion formed integrally with the drill bit body and a rotary cutter rotatably supported on the trunnion by bearing means. The bearing means consist of at least two rows of balls which ride between an inner raceway groove formed integrally in the trunnion and an outer raceway groove formed in the interior peripheral surface of the rotary cutter. A filling hole or port is provided in the drill bit body which terminates at its inner end in each raceway so that the balls of the corresponding row may be assembled in the annular space between the trunnion and rotary cutter. A filler pin closes the corresponding filling hole or port and has a terminal end which complements the cross section of the raceway groove.
摘要:
A ball bearing adapted for axial movement on a shaft is comprised of a cage having guideways defining endless paths having axially extending portions for loaded and unloaded balls, and semicircular end portions. An outer sleeve surrounds the central portion of the bearing and defines races for balls in the endless paths. End rings on the axial ends of the bearing radially outwardly cover the semicircular guideway portions. The semicircular guideway portions have outwardly convex bottoms, and the end rings have concave recesses in their inner surfaces aligned with the semicircular guideways. The convex portions of the guideways and the concave portions of the recesses have common centers of curvature extending parallel to the bearing axis and displaced outwardly therefrom.
