摘要： The invention relates to a device for compensating axial thermal expansion of a roller bearing arrangement having a bearing ring (6) with a receptacle space for a thermal expansion element (10). In order to provide a compensation device which, while having a simple and cost-effective design, also permits the use of a thermal expansion element made of inexpensive material with relatively low durability and/or relatively low temperature coefficient, the bearing ring (6) is composed of two partial bearing rings (6a, 6b). In this context, the first partial bearing ring (6a) has a roller body running face (7), and the second partial bearing ring (6b) has an outer lateral face (13). The partial bearing rings (6a, 6b) bound the receptacle space (21) between them and can be displaced relatively to one another at least in the axial direction (A) owing to thermally induced changes in volume of the thermal expansion element (10).

摘要： The screw a spindle nut (1) arranged on a threaded spindle (2). The spindle nut is provided with screw-shaped ball grooves (3, 4) that are wound around the threaded spindle. Balls (6) are arranged in a ball channel (5) formed by the both ball grooves. The ball channel is finite, so that the balls are movable back and forth between ends along the ball channel. Each end of the ball channel is formed by a closure part (8) which is attached at the spindle nut. The closure part is made of plastic in an injection process, and is formed by a closure ring (9) arranged coaxially to the spindle nut.

摘要： The ball-and-the screwdriver has a spindle nut (1) on a rolling-ball spindle, with balls (3) running in grooves (4, 5). The drive wheel (20) is fixed to the spindle nut, which can be moved on a rolling bearing (7) on a housing (8). The outer ring (9) has a ring (15) gripping rounds spindle, with a bearing running surface (10, 11) inside it.

摘要： A ball screw drive (2) is coupled to a spindle nut (1) by a number of spheres (3) in endless helical channels (4). The spindle nut has first (11) and second (12) sections separated by an interval, each with a channel. The two spindle nut sections are joined by a one-piece link-section (13, 16).

摘要： A liquid molding material is filled and hardened within the bearing adapter (17) of a belt drive carrier (13) to fix each pulley (8,10) to the adapter in a direction transverse to the axis of rotation of the pulley. The screw shaft (2) and drive shaft (9) of the pulleys are individually supported on bearings (14,15) in the bearing adapter. An independent claim is also included for an electromagnetic steering assist.

摘要： The cam plate mechanism has a roller which is a support roller in curved path (23) which is engaged with another roller which is balancing roller (11). An elastic race is integrated with the balancing roller whereby race is arranged between the coupling element (8) and balancing roller and encompassing the axis of rotation. The race is elastically prestressed in the radial direction of axis of rotation as well as opposed in radial direction of balancing roller.
