According to one exemplary embodiment of the present invention a worm shaft subassembly for supporting a worm shaft is provided. The worm shaft has a worm shaft radial load, a worm shaft axial load, and a worm shaft axial travel. The worm shaft subassembly includes at least one damping member to support the worm shaft axial load. The at least one damping member has at least one damping member axial load. The at least one damping member limits the worm shaft axial travel. The worm shaft subassembly also includes a bearing to support the worm shaft radial load and the at least one damping member axial load.

A method is disclosed for preparing a steering gear for subsequent use as part of a steering system of a motor vehicle, the steering gear includes at least a gear and a pinion meshing with the gear, and at least the teeth of the gear and/or of the pinion being made of plastic. The pinion is first pressed against the gear by way of a first force, while at the same time the pinion and the gear are rotated first in a first direction of rotation and subsequently in the second direction of rotation. The first force is preferably selected so high that plastic deformation of the plastic of the pinion and/or of the gear is achieved. Subsequently, the pinion is pressed against the gear by way of a second, defined force, which is less than the first force, the second force being permanently set.

A planetary reduction gear using a helical gear is configured such that a rear-stage sun gear is rotatably supported by a device housing via a radial bearing on one side in the direction of a center axis, and is rotatably supported by a rear-stage planetary carrier via a thrust bearing on the other side. The rear-stage planetary carrier is rotatably supported by the device housing via a rear-stage carrier bearing. A preload is applied to the thrust bearing by a preload mechanism mounted to the rear-stage planetary carrier. Displacement of the rear-stage sun gear caused by a thrust force generated due to engagement with a rear-stage planetary gear can be suppressed, and an angle error between input rotation and output rotation can be suppressed.

A method for setting an axial preload force of a roller screw drive (3) which is rotatably mounted in a housing (2) by means of bearings (4, 5) which are axially spaced apart from one another. The housing (2) is split transversely with respect to the thrust rod (7) into a first and a second housing part (8, 9). The roller screw drive (3) is inserted with the two bearings (4, 5) into the second housing part (9). An axial preload force is applied which is transmitted from the first bearing (4) via the roller screw drive (3) to the second bearing (5). An axial load spacing (“X”) between the bearing supporting surface of the first bearing (4) and a second housing edge (31) of the second housing part (9) is measured. An adjusting nut (10) is screwed into the first housing part (8) until an axial adjustable spacing between the end-side adjusting nut supporting surface (12) and the first housing edge (30) of the first housing part (8) is the same size as the measured axial load spacing (“X”). The adjusting nut (10) is then secured in place in the first housing part (8), and the two housing parts (8, 9) are connected to one another, with the result that both bear against one another by their housing edges (30, 31).

A transmission, including an outer shell (1), an inner shell (2), a drive disk (3), a plurality of T-shaped teeth (4), a gear (5), a tooth seat (6), an adjustable nut (7), balls (8), inner balls (9), outer balls (10), an inner protective frame (11), an outer protective frame (12), rollers (13), a first sealing ring (14), a second sealing ring (15) and a third sealing ring (16). Transmission clearance can be adjusted freely at any time, the meshing of the T-shaped tooth and the gear is a real surface meshing, and almost all the teeth participate in force transmission simultaneously. Therefore, the transmission has high precision, high mechanical properties, and long service life.

A cam-locking system for use with a retractable driveshaft that includes a housing, a cam carrier located at least partially the housing, and a cam rotatably coupled to the cam carrier. Translation of the cam carrier along a central axis allows the cam to rotate into cooperative engagement with a catch recess on an interior surface of the housing, preventing the cam carrier from translating backwards, and thereby maintaining the retractable driveshaft in an engaged position. Further advancement of the cam carrier allows that cam to rotate into and unlocking gap in the interior surface of the housing, which enables the cam carrier to translate backwards along the central axis below the locked position, thereby disengaging the retractable driveshaft.

A gear unit includes a shaft, rotatably mounted via a first bearing, a housing part, and a cover connected to the housing part. The shaft has a threaded region onto which a nut is screwed, and a spacing sleeve and a disk are arranged between the nut and an inner ring of the spacing sleeve. The greatest outer diameter of the disk is greater than the greatest outer diameter of the spacing sleeve; the greatest radial distance of the disk relative to the rotational axis of the shaft is greater than the greatest radial distance of the spacing sleeve relative to the rotational axis of the shaft; and/or the radial spacing region covered by the disk and relative to the rotational axis of the shaft contains the radial spacing region covered by the spacing sleeve.

Electric motors are disclosed. The motors are preferably for use in an automated vehicle, although any one or more of a variety of motor uses are suitable. The motors include lift, turntable, and locomotion motors.

A fixing structure for an auxiliary bearing of an electric drive assembly and an electric drive assembly are disclosed. The fixing structure comprises a bearing pressing plate, a bolt, a lock nut, an auxiliary bearing outer ring and an auxiliary bearing inner ring. The bearing pressing plate is provided with a through hole, the housing is provided with a threaded hole, and the bolt passes through the through hole and is fixed in the threaded hole. The bearing pressing plate pre-tightens one side of the auxiliary bearing outer ring, and the housing limits a position of the other side of the auxiliary bearing outer ring. The lock nut is sleeved on the shaft to pre-tighten one side of the auxiliary bearing inner ring, and the gear limits a position of the other side of the auxiliary bearing inner ring. The bearing fixing solution has a simple structure; moreover, the inner and outer rings of the bearing are pre-tightened by threads, thereby avoiding over-positioning of the bearing, reducing the running noise of the bearing, and improving the service life of bearing.

The disclosure relates to a transmission housing unit and to a transmission unit which has said transmission housing unit. The transmission housing unit has a housing main body which has a through hole, through which a shaft which penetrates the housing main body in the axial shaft direction can be pushed into the housing main body, a wedge-shaped compensation element for axial play compensation between the shaft and the housing main body which engages around the shaft at least in a U-shaped or arcuate manner, and a pre-stressed spring element which is arranged between the obtuse end of the compensation element and the housing main body. The compensation element can be displaced radially in the direction of the shaft axis along a guide surface of the housing main body between an assembly position and an active position.
