摘要:
An automatic adjustment arrangement for disk brakes has a flanged threaded nut and a threaded spindle threadedly coupled thereto arranged between the brake piston and the hand brake piston. The flange of the threaded nut is axially form-locked and radially displaceable relative to the brake piston. The threaded spindle is rotatably supported in a rolling bearing which is radially displaceable. The hand brake piston and threaded spindle are frictionally coupled. The extension of the adjustment member is produced by rotation of the threaded spindle. To avoid malfunctions, an automatic centering of the entire adjustment element relative to the brake piston as well as relative to the housing is provided. Manufacturing and assembly errors are thereby compensated for. The positions of the threaded spindle and threaded nut can be interchanged.

A bearing cage having two rings connected by webs for angular contact two-row ball bearings where the bearing cage ring has cage pockets of a partial spherical shape. The radial plane of the bearing passes through the centers of the partial spheres and is placed off-center with respect to the bearing cage ring faces, the distance between the radial plane and the face less distant from the radial plane being preferably equal to the radius of the ball.
摘要:
A cage for a ball bearing, especially for an inclined ball bearing, is comprised of two side rings connected together by webs, with one of the side rings being outside of the pitch circle and the other side ring being inside of the pitch circle. Circumferentially resilient axially extending projections are provided extending from one of the side rings toward the other, radially inwardly or outwardly of the pitch circle, and recesses are formed by the webs and projections in the regions of minimum spacing between the balls.

Pulley for driving the shaft of a water pump, especially a pump for the cooling system of an internal combustion engine, the shaft being designed to be integral with a pulley body carrying the rim of the pulley, characterized in that the rim (15, 25, 31, 37) is designed as a sleeve and is attached to the pulley body (13, 22, 29, 39) in a form-locking or friction-locking manner.
摘要:
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.
摘要:
A method for producing a cage, especially a roller cage of sheet material by punching out the roller element pockets, consisting of the steps of stamping the sheet material in the direction of the sheet thickness in at least predetermined areas of the punching line for forming the rolling element pockets and thereafter forming the pockets by a punching operation.
摘要:
Roller bearing cage, especially for cylindrical roller bearings or needle bearings, which presses the rolling elements elastically in the radial direction against a raceway to prevent rippling, characterized in that, at least at one point (6), the cage (1) has notches (8) proceeding from the end surfaces (10) and a connecting part (11), which is rigid in the peripheral direction and which is located between the notches; and in that, in the peripheral direction, a recess (9), extending approximately across the width of the cage, is provided on one or both sides next to notches (8), this recess forming the boundaries of elastic sections (12).
摘要:
A device for sealing and generating electrical pulses in a bearing assembly including fixed and rotating bearing rings especially a wheel bearing for motor vehicles. The device consists of a sealing section on the fixed bearing ring with an embedded pulse generator for detecting rotational movement and a sealing section on the rotating bearing ring having cells a certain distance apart from each other which activate the pulse generator. The fixed bearing ring (4, 19) rotates with respect to the sealing section (2) which is secured against rotation by way of a machine element (1, 24), which holds the fixed bearing ring (4, 19).
摘要:
The invention concerns a device for synchronous guiding a roller bearing cage for a roller bearing performing swivel motions, the device comprising a roller cage and bearing parts which swivel relative to one another, the roller cage provided with a pinion gear formed on two diametrically opposed sites with curved toothed segments having different pitch circle diameters, the toothed segments meshing with the teeth of the bearing parts.
