The present disclosure provides a remote mount for an idler gear assembly, comprising: a gear mounting plate including a plurality of bores configured to receive a corresponding plurality of fasteners to mount a gear assembly to the gear mounting plate; and an attachment bracket including a plurality of mounting openings configured to receive a corresponding plurality of bolts to mount the remote mount to a cylinder head. The gear mounting plate supports the gear assembly such that a gear of the gear assembly rotates about an axis that is parallel to an axis of a crankshaft of an engine and the attachment bracket mounts to an upper surface of the cylinder head.

An adjustment drive for a motor-adjustable steering column for a motor vehicle includes a drive unit having a transmission in which there is mounted a drive wheel. The drive wheel can be driven to rotate about a drive axis and is in operative engagement with a transmission wheel which is mounted in the transmission so as to be rotatable about a transmission axis. The transmission has a drive module, which includes the drive wheel, and a transmission module, which includes the transmission wheel. The drive module and the transmission are connected to one another by a joining connection.

A bearing adjustment assembly is provided. The assembly includes a worm engaged with a worm gear. The assembly also includes a worm bearing located proximate an end of the worm. The assembly further includes a spring disposed in a spring bore defined by the housing. The assembly yet further includes a compensation mechanism engaging the worm bearing and the spring, the compensation mechanism being adjustable to bias the worm bearing to maintain or adjust a gear mesh load between the worm gear and the worm, wherein compression of the spring adjusts the compensation mechanism biasing of the worm bearing. The assembly also includes a spring retainer comprising a pin retainer portion disposed within an interior of the spring, the pin retainer portion extending from a main body portion of the spring retainer.

Disclosed herein is a steer-by-wire type steering actuator. In accordance with one aspect of the present disclosure, a steering actuator may include: a first reducer including a worm configured to rotate by receiving a rotational force of a motor and a worm wheel configured to rotate in engagement with the worm; a pinion shaft coupled to a center of the worm wheel and configured to rotate together with the worm wheel; a second reducer including a first gear formed on the pinion shaft, and an output shaft configured to operate a pitman arm while rotating by receiving a rotational force through a second gear engaged with the first gear; a first gear housing configured to receive the worm and coupled to the motor; a second gear housing provided with a first mounter for receiving and mounting the pinion shaft and a second mounter formed apart to communicate with the first mounter and configured to receive and mount the output shaft, and coupled to the first gear housing; and a holder configured to rotatably support the pinion shaft and having a rotational center axis eccentric with respect to a central axis of the pinion shaft to adjust an axial distance between the pinion shaft and the output shaft.

A two-stage actuating gear mechanism comprises a spur gear transmission as the first transmission stage and a harmonic drive as the second transmission stage. A spur gear transmission gear with inward facing teeth is designed simultaneously as a component of a harmonic generator of the harmonic drive. A gear with outward facing teeth that meshes with the gear with inward facing teeth is rigidly connected to a rotor of an electric motor, the motor housing of which is secured to the transmission housing of the harmonic drive. The motor housing is positioned relative to the transmission housing by means of a centering device which is eccentric to the rotational axis (A.sub.E) of the rotor. An adjustable backlash between the gear with outward facing teeth and the gear with inward facing teeth is provided by a pivoting capability between the motor housing and the transmission housing.

A drive unit includes a housing and a pinion having a head and a shaft. The shaft extends through a pinion-support portion of the housing. A tail bearing supports the shaft and has an outer race fixed to the pinion-support portion and an inner race received on the shaft. The inner race is brazed to the shaft. The drive unit may be assembled by installing a tail-bearing cup and a head-bearing cup in the housing and inserting the pinion in the housing with the shaft extending through the cups. The method further includes installing a tail-bearing cone onto the shaft to be seated on the tail-bearing cup and urging the cups toward each other. The method also includes brazing the tail-bearing cone to the shaft while the cups are urged toward each other.

The present invention relates to a gearbox assembly comprising a housing, a cover, a screw rod that is inserted through said housing along a first direction, a worm wheel integrally formed on said screw rod, and a worm arranged in the housing along a second direction perpendicular to the first direction, said worm being in meshing transmission with the worm wheel, wherein said worm is driven into rotation by a driving shaft, so that the worm drives said worm wheel and said screw rod into rotation through a kinetic pair; said screw rod moves a lifting mechanism attached to the screw rod in a vertical direction through screw transmission; and a stop pin is arranged on said housing, said stop pin being positioned in the direction of extension of a free end of the driving shaft of the worm against the free end. In addition, the present invention further relates to a headrest actuator comprising said gearbox assembly.

A drive (1) with a housing (2) and a toothed part (4) which is mounted rotatably relative thereto with a wire race bearing (15), wherein a threaded ring (23) is screwed onto the housing (2) or the toothed part (4), said threaded ring axially fixing the wire race bearing (15) and permitting an adjustment.

An arrangement includes a friction-bearing supported first gear with a pitch diameter d.sub.1 and a friction-bearing supported second gear with a pitch diameter d.sub.2. The first gear and the second gear intermesh with each other, and a distance a between an axis of rotation of the first gear and an axis of rotation of the second gear increase during operation by up to .sub.a.sup.wear. A nominal dimension N.sub.a is provided for the distance a, wherein N.sub.a=(d.sub.1+d.sub.2.sub.a.sup.wear)/2.

A variety of scissors gear assemblies are disclosed that utilize integral parts or common tools to align teeth of the scissors gear assembly. Methods of use are also disclosed.
