Abstract: A mounting of a shaft in the bore of a housing by two antifriction bearings mounted in a sleeve at a distance from each other, the said sleeve being arranged in the bore of a housing having a higher coefficient of thermal expansion than the mounting elements and being provided with a radially outwardly directed flange, the flange being pressed by elastic spring means against a contact surface of the housing traversed by the bore whereby frictional engagement exists between the said surface and the flange characterized in that the sleeve and housing are axially braced with the elastic spring means preferably yielding axially and abutting a housing surface plane parallel to the contact surface and radially supporting the sleeve in relation to the housing, and a method of assembling the said mounting.

Abstract: A rotatable spindle is carried in bearings located in one end of the bore in an adapter. The other end of the adapter is fixed in a machine base so as to cantilever the adapter. A damping chamber is formed along the adapter length between the machine base and the adapter, and a damping medium is provided in the damping chamber to control vibrations of the cantilever assembly. In one embodiment, a viscous damping medium is utilized to effectuate squeeze film damping. In an alternate embodiment, a visco-elastic damping medium is utilized in the damping chamber.

Abstract: A free floating mount for the holographic disc of a scanner which enables centrifugal force developed by rotation of the disc to bring the disc into perpendicular relationship with the axis of the disc motor shaft and prevent disc wobble, comprising, a first self aligning couple composed of a pin and socket for supporting the disc on the end of the motor shaft, the shaft and disc having coaxial bores therethrough; a tensioning cable assembly extending through the motor shaft and disc bores, one cable segment of the cable assembly being attached to a retaining ball receivable in a socket in the disc, the retaining ball and socket forming a second self aligning coupling; a second cable segment at the opposite end of the cable assembly having a retaining ball attached thereto receivable in a socket in the motor shaft end and forming a third self aligning coupling; an extension spring interconnecting the first and second cable segments to form the cable assembly whereby the motor shaft and disc are biased through

Abstract: A rotary actuator assembly, for use as part of a servomechanism for positioning one or more data recording or data recovering heads over selectable data storage tracks at selectable radii on one or more rotary data storage discs, comprises a head support arm pivoted to rotate with a shaft held betwen two bearings in a yoke, where one of the bearings is a composite bearing allowing both axial and rotational movement of the shaft and the other bearing allows only rotational movement of the shaft, the two bearings co-operating to fix the position of the shaft while allowing its free rotation and allowing axial movement of the shaft whenever axial force exceeds a predetermined limit, thereby preventing undue bearing play or bearing binding attendant upon prior art designs.

Abstract: A support assembly for a rotating shaft utilizing an annular spring is disclosed. A series of support rods are spaced on the interior and exterior sides of an annular spring to define spring segments which act as a spring for supporting the journal. A squeeze film damper cavity may be incorporated either as part of the spring support structure or separately within the assembly to provide the necessary damping.

Abstract: In a bearing device of an exhaust gas turbocharger having tandem rolling-contact bearings, the bearing support rings (5,6) have dogs (16) on their mutually facing end surfaces, each of which dogs penetrates into an opposite recess (17) with axial clearance (18) and tangential clearance (19). An even number of rotationally symmetrically located spring rods (7) extend from a bearing flange (8) connected to the bearing housing (2) through the bearing support rings (5,6) and into a support ring (9) connected to the bearing housing (2), a centrally located collar (14) on the spring rods being located alternately, without clearance, in one or the other bearing support ring (5,6).In this bearing device, the effective bending length (L) of the spring rod (7) is relatively large compared to the total width of the bearing (B). By this means, the bending stress in the spring rods (7) can be kept low or the axial installation length (B) of the bearing device can be reduced.

Abstract: A clutch release bearing is disclosed comprising an operating member controlled by an actuating member, e.g., a release fork, a drive member attached axially to the operating member and responsive to the operating member for coacting with a clutch release mechanism, e.g., a clutch diaphragm spring. The operating member has a metal axial sleeve which is received on a guide member and a metal transverse flange bearing on one side against the actuating member and on the other side against the drive member. A spacer member of synthetic material is interposed axially between the flange and the drive member and detents or elastically deformable pawls are operably disposed between the spacer member and the sleeve for fixing the spacer member in axial position thereon. The detents or pawls may be formed between axial slots in the inner wall of the spacer member. The outer wall has an annular transverse land against which the drive member, for example, the outer race of a ball bearing, may bear.

Abstract: The support arrangement according to the present invention has an inner strap which surrounds the ball-bearing outer race or a bush receiving the ball bearing, and an outer strap intended for installation in a casing. These two straps are connected to one another by bending spring bars uniformly distributed over the periphery of the straps, in such a way that a coaxial gap is present between them.

Abstract: In a circular knitting machine problems may arise from differential thermal expansion, particularly in a radial direction, or rotatable carrier disc (22) and a coaxial bearing body (16) in which it runs by means of a bearing (36). In order to overcome this by absorption of the differential expansion, one of the running surfaces of the bearing is formed on or supported by a resiliently yieldable part (34), which preferably also preloads the bearing. As alternatives to the illustrated embodiment, in which the yielding is axial, as indicated by the arrow A, the yielding may be radial, and also the yieldable part may be on the bearing body (16) rather than the carrier disc (22).

Abstract: Play between an axially pre-tensioned ball bearing assembly mounted on a rotating motor shaft and the bore of the motor's end shield, in which the bearing is received, is prevented by use of a disc having a formed-on, wedge-shaped rim, which is pressed into the space between the bearing's outer surface and the wall of the bore. Centering for the pretensioning spring can be provided by an oppositely protruding, wedge-shaped rim, also formed on the disc at the time of manufacture.
