摘要:
There is disclosed herein a bearing for highprecision transport spindles used in machines for electrical reproduction technology, machine tools, measuring installations and the like, wherein axial movement due to bearing tolerances are eliminated by the bearing device of this invention. The radial and axial bearing of the spindle are decoupled from one another by means of the bearing device, thereby eliminating the axial dislocation errors.
摘要:
A tensioning arrangement for a bearing ring, which introduces a compressive force towards a rotational centre of the bearing ring, to prevent the bearing ring distorting as a shaft supported by the bearing turns. The tensioner arrangement includes a strap and a tensioner. The strap has a connector at each end, and tensioner has an element for connecting to the connectors. The tensioner also has an element for applying tension to the strap. In use, the strap is arranged around the bearing ring and a circumferential length of the strap in contact with the bearing ring is reduced, thereby applying compressive force to the bearing ring.

A distributed load bearing including an outer flex ring, a load distribution spring, and a retainer. The outer flex ring is configured to be positioned radially outwards of a shaft. The load distribution spring is preloaded and positioned radially outwards of the outer flex ring. A radially inner surface of the load distribution spring contacts the outer flex ring. The radially inner surface is an arc defined by a first radius when the load distribution spring is in a lower load distribution mode, and a second radius when the load distribution spring is in a higher load distribution mode. The retainer is positioned radially outwards of the load distribution spring, and the retainer angularly and radially positions the load distribution spring.

A steering spindle arrangement includes a spindle bolt (2), an axle beam (1) that is secured to a central part (2b) of the spindle bolt (2), a stub axle (5) that has a first arm (6) that is rotatable around a first part (2a) of the spindle bolt (2) via a first bearing (11) and a second arm (8) that is rotatably arranged around a second part (2c) of the spindle bolt (2) via a second bearing (22). An adjusting mechanism (4, 18) makes it possible to adjust a variable rotation resistance for the stub axle (5) when it is rotated around the spindle bolt (2).
摘要:
The present invention relates to a reducer of an electric power steering apparatus. According to the exemplary embodiments of the present invention, a damping member is provided on an outer circumference surface of a bearing bush so that impact between a worm shaft bearing and a bearing bush can be dampened, and noise generated at the time of impact can be reduced.
摘要:
A driving device for an adjusting device of a motor vehicle is provided. The driving device comprises a housing or housing section which at least partially encloses components of the driving device and an electric-motor-driven drive shaft which extends in a longitudinal direction and which is axially supported on the housing or housing section at least via one end. An active bearing element is arranged between the housing or housing section and the drive shaft at at least one end of the drive shaft, said bearing element being suitable for acting on the drive shaft axially in the longitudinal direction during the operation of the driving device.

The present invention provides a device and a method to enhance thrust load capacity in a rotor-bearing system. The load-enhancing device comprises a stator and a rotor arranged in such as way as to achieve a magnetic thrust load capacity enhancement by employing at least one permanent magnet, which produces an attracting force or an expulsing force between the rotor and the stator.
摘要:
An apparatus and method for preloading roller bearings which rotatably support a pinion shaft in a differential gear assembly includes a drive mechanism which selectively engages and rotatably drives the yoke of the differential gear assembly in a counterclockwise direction as viewed from the pinion shaft threaded end. A dead shaft engages the pinion shaft nut and rotates therewith. A brake is coupled to and selectively restrains or allows the dead shaft to rotate with the nut. Preventing the dead shaft and nut from rotating causes the nut to be threadingly received onto the pinion shaft and load the bearings. Disengaging the brake and allowing free rotation of the dead shaft and nut allows sensing of the bearing preload condition within the differential gear assembly housing.
