A steering gear includes a gear wheel, a screw pinion meshing therewith, and a screw pinion shaft that includes the screw pinion. The screw pinion shaft is mounted on one side of the screw pinion in a fixed bearing. The steering gear includes a rotary bearing which comprises an inner bearing shell and an outer bearing shell. The outer bearing shell is connected to an inner ring of a swivel ring. The inner ring is connected to an outer ring of the swivel ring by a torsion web so as to pivot about a pivot axis. The torsion web runs at a distance from a supporting surface. The distance is dimensioned such that the torsion web does not contact the supporting surface when the screw pinion shaft is not loaded with a torque, and partially contacts the same when the screw pinion shaft is loaded with an operating torque.

A load cell for determining a radial force acting on a crankshaft includes a receiving sleeve for receiving a ring of a bearing; a fastening ring for attaching the load cell in a transmission housing; axial support areas provided on the fastening ring for axially supporting the ring of the bearing; and measuring regions for receiving radial forces of the receiving sleeve and which connect the receiving sleeve with the fastening ring, wherein strain sensors are attached to at least two of the measuring regions; and wherein the measuring regions comprise measuring lugs formed as angle brackets.

An electromechanical steering system may include a reduction gearbox where a worm gear is mounted in first and second bearings rotatably about a longitudinal axis. Rolling elements are disposed between inner and outer rings of the bearings. The inner rings are rotationally fixed on a shaft driven by the worm gear. A spring element is disposed between the inner ring of the second bearing and the worm gear. The spring element has an at least partially annular main body that when installed extends coaxially with the longitudinal axis. Spring arms in a circumferential direction are spaced apart from the longitudinal axis emanating from an external circumferential side of the main body. A first spring arm has a first leg that points away from the longitudinal axis and a second leg on which a free end is disposed, with the second leg running at least partially parallel to the longitudinal axis.

A bearing unit is provided with a strain element for torque detection. The strain element is provided with a first annular part attached to a rotation-side member, a second annular part attached to a load-side member, and a plurality of ribs serving as strained parts linking the first annular part and the second annular part together. One of an inner race and an outer race is integrally formed on the first annular part of the strain element. Deformation, which occurs in the ribs of the strain element due to torque exerted on the rotation-side member from the load-side member, is detected by a strain gauge, etc., and converted to torque. The strain element for torque detection can be incorporated into a motor, a reducer, or another rotary propulsion unit without the need for a dedicated installation space and without the need for fastening fittings, etc.

A motor vehicle electric motor assembly includes a motor housing having an annular wall extending from a housing first end to an opposite housing second end about a central axis to bound a cavity. The housing first end has a base configured to support a bearing housing. A motor shaft extends along the central axis between a shaft first end and a shaft second end. A rotor is fixed to the shaft for rotation about the central axis. A stator is supported by the annular wall in radially spaced relation from the rotor. A bearing is fixed in the bearing housing to support the shaft first end for rotation about the central axis. An end cover assembly is fixed to the housing second end. The end cover assembly has a motor shaft opening with a periphery of the motor shaft opening supporting the shaft second end for rotation about the central axis.

The invention relates to a gear motor (1) for a motor vehicle wiper system including an electric motor (2) including a rotor (20) and a rotation shaft (22) fixed to the rotor, a reduction gear mechanism (3) including a worm/worm wheel system, a device for generating an axial load configured to offset axial play of the rotation shaft (22), including a retaining wedge (6) mounted in a sliding manner in a radial direction of said rotation shaft (22), said retaining wedge (6) exerting an axial load on the outer race of a ball bearing (5) configured to guide the rotation shaft. According to the invention, said retaining wedge (6) is arranged in an intermediate position between the seat (40) of the bearing support (4) and the worm (30) directly adjacent to the worm wheel (31), said axial load (Fa) exerted by the retaining wedge (6) on the outer race (51) of the ball bearing (5) being in the direction away from the worm (30).

Provided is a gear motor including a motor, a speed reducer, a first detector disposition section in which a first rotation detector that detects rotation of a rotor shaft is disposed, a second detector disposition section in which a second rotation detector that detects rotation of an output member of the speed reducer is disposed, and a third detector disposition section in which a torque detector is disposed, in which the gear motor is operable when the first rotation detector is disposed in the first detector disposition section, the second rotation detector is disposed in the second detector disposition section, and the torque detector is disposed in the third detector disposition section, and is operable even when a portion thereof is disposed.

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 rolling bearing for mounting a driving worm of a power-assisted steering system of a vehicle includes a rotatable inner ring and a rotationally fixed outer ring. Rolling elements arranged between the inner and outer ring are guided by a channel-shaped first raceway arranged on a radially outer side of the inner ring and by a channel-shaped second raceway arranged on a radially inner side of the outer ring. The second raceway includes a cross-sectional profile that varies around its circumference. The cross-sectional profile allows laterally offset rolling elements to roll and thus tilting of the inner ring about a tilting axis orthogonal to the axis of rotation of the rolling bearing if the tilting axis assumes a predetermined tilted position in the circumferential direction of the second raceway and limits tilting of the inner ring to a minimum when the tilting axis is angled 90° to the tilted position.

Provided are a motor device and a method for manufacturing the same that can accurately and consistently provide a support shaft to a case and enhance the strength for fixing the support shaft to the case. A small-diameter part having a smaller diameter than a large-diameter part is formed through drawing. The large-diameter part and a step part are embedded in a gear case. The small-diameter part is exposed outside the gear case. The dimensional accuracy (dimensional tolerance ±α) of the external diameter of the small-diameter part is enhanced. The small-diameter part can be set, without rattling, in a lower mold for molding the gear case. Consequently, the support shaft can be accurately and consistently provided to the gear case. Because the large-diameter part and the step part are embedded in the gear case, the resistance of the support shaft against pulling from the gear case can be enhanced.
