An electromechanical power steering system for a motor vehicle may include a driving worm that is driven by an electric motor and acts on a worm gear that is coupled to a steering shaft. The driving worm may be mounted in such a way that it can rotate about its worm axis. More particularly, the driving worm may be mounted in a bearing that is held in a mount. The mount may prestress the driving worm in a direction of the worm gear. In some examples, the mount is torsionally weak about a torsion axis that is positioned perpendicularly with respect to the worm axis.”

The invention relates to a transmission drive assembly (10) having a drive motor (11) the drive shaft (23) of which protrudes with a portion (25) thereof into a transmission housing (12), wherein the drive shaft (23) is arranged on the side facing the transmission housing (12) in a bearing (32) which is held in a form-fit or force-closed manner in a substantially sleeve-shaped holding element (35; 65) which is arranged in a holding fixture (27) of the transmission housing (12). According to the invention, in an installation position for introducing and positioning the holding element (35; 65) in the holding fixture (27) of the transmission housing (12), the holding element (35; 65) is positioned in a first axial end position defined by an abutment element (30) of the drive motor (11), and, in an end position of the drive shaft (23) in the transmission housing (12), the holding element (35; 65) can be slid by means of a sliding element (47; 61; 62, 63) on the drive shaft (23) into a second axial end position which is axially remote from the at least one abutment element.

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.

An electromotive furniture drive includes a housing having an opening, a drive motor attached to the housing and including an output shaft, and a standpipe inserted into the housing laterally in a form-fitting manner. The standpipe has an outer wall formed with a transverse groove, with a lifting spindle arranged in the standpipe. A gear assembly is arranged in the housing and configured to couple the output shaft of the drive motor to the lifting spindle. A locking element is configured to engage in the transverse groove and held in a recess in the housing.

A power steering device includes a bearing configured to rotatably support the tip side of a worm shaft, the gear case housing the worm shaft and a holder housed in a housing hole provided in the gear case and configured to house the second bearing. The holder includes the first holder having a holding part configured to hold the outer periphery of the bearing and the opening part configured to expose a part of the outer periphery of the bearing, the second holder having a guide part configured to guide a movement of the bearing toward a worm wheel as the outer periphery of the bearing comes into contact with the guide part through the opening part and a spring configured to bias the bearing toward the worm wheel via the first holder.

A transmission housing (1) comprising a shaft (2) housed at least partially inside the housing (1) and, mounted on said shaft (2), at least one rotary element (3) and a rolling bearing (4), the rolling bearing (4) comprising an inner ring (5) and an outer ring (6) that are coaxial, separated from each other by rolling members (7). The housing (1) further comprises a blind or through tubular body (8) mounted on the shaft (2) and interposed at least partially between the shaft (2) and the rotary element (3), the rotary element (3) being mounted rotatably secured to the tubular body (8), and the tubular body (8) being kept rotatably secured to the shaft (2) by the inner ring (5), referred to as the constriction ring, of the rolling bearing (4), force-fitted onto said tubular body (8).

A noise reduction apparatus for an electric power steering system may include a worm wheel rotatably and integrally coupled to a steering shaft connected to a steering wheel; a worm gear shaft to be rotatably operated by rotational force of an electric motor and formed with a worm gear to be meshed with the worm wheel; a tilt bearing provided between the worm gear shaft and the electric motor to rotatably support one end of the worm gear shaft; a support bearing for rotatably supporting the other end of the worm gear shaft; a plurality of pressing pins for pressing the support bearing; and a plurality of elastic members for elastically supporting the plurality of pressing pins respectively.

A reducer of an electric power steering apparatus includes: a worm shaft having a first end thereof supported by a first bearing coupled to a housing and a second end supported by a second bearing coupled to the housing; a damper axially supported on an outer race of the second bearing; and a damper support member having a first side axially supported on the damper and a second side supported on an inner face of the housing. The worm shaft can be assembled with constant rotational torque at an accurate position with respect to the centers of the bearings at the opposite ends. And, the axial and radial movements of the worm shaft can be buffered and the load applied to the worm shaft in the direction in which the worm shaft is engaged with the worm wheel can be reduced.

A landing gear system and method of actuating the landing gear system, the system including a first leg assembly, a second leg assembly, a cross-shaft arranged between the two leg assemblies, and a landing gear actuator. The landing gear actuator includes a motor and a coupling shaft which is arranged to couple and decouple the landing gear actuator from the cross-shaft.

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.
