A drive train for a rescue hoist includes a first stage, a second stage, and a third stage. The first stage receives an input from a motor and the third stage provides rotational power to a cable drum. The first stage, second stage, and third stage are disposed coaxially within a common housing. The first stage provides a first speed reduction, the second stage provides a second speed reduction, and the third stage provides a third speed reduction between the motor and the cable drum. The common housing includes a mounting flange for mounting the drive train to the rescue hoist.

A landing leg assembly for a heavy duty commercial vehicle includes a first leg member defining an interior space, a second leg member telescopingly engaging the first leg member and movable between a retracted position and an extended position with respect to the first leg member, a gear assembly at least partially located within the interior space of the first leg member and operably coupled to the second leg member and configured to receive an input from a user to move the first leg member between the retracted and extended positions, the gear assembly including a shaft member and a gear member fixed for rotation with the shaft member, and an integral, single-piece bearing member including a bore that rotatably receives the shaft member, wherein the bearing member comprises a powdered metal and is directly welded to the first leg member.

A gear unit includes: a first gear and a second gear which are disposed about a first axis; an input shaft disposed so as to be rotatable about the first axis; and an intermediate gear disposed between the first gear and the second gear. The intermediate gear is disposed about a second axis tilted with respect to the first axis. The intermediate gear includes an inner ring portion and an outer ring portion disposed so as to be rotatable relative to the inner ring portion. The inner ring portion is configured to be rotated with rotation of the input shaft. The outer ring portion is configured to mesh with the first gear and the second gear.

A modular pinion shaft that includes a tubular member having a first end and a second end, a first pinion gear member secured to the first end by a plurality of fasteners, and a second pinion gear member secured to the first end by a plurality of fasteners. Gear teeth of each of the pinion gear members are aligned by one or more indexing members disposed between the tubular member and each pinion gear member.

An electric drive system for a vehicle includes a motor housing and a gearbox housing that is mountable to the motor housing at a predetermined number of rotational positions.

A modular pinion shaft that includes a tubular member having a first end and a second end, a first pinion gear member secured to the first end by a plurality of fasteners, and a second pinion gear member secured to the first end by a plurality of fasteners. Gear teeth of each of the pinion gear members are aligned by one or more indexing members disposed between the tubular member and each pinion gear member.

Example bicycle sprocket assemblies are described herein. An example sprocket assembly includes a cassette formed by a plurality of sprockets arranged in increasing diameter order from a first end to a second end of the cassette opposite the first end. The cassette has a passageway extending between a first opening in the first end and a second opening in the second end to receive a driver hub. An outboard portion of the passageway is formed between a midpoint of the cassette and the first end of the cassette. The cassette further includes a torque transmitting profile located within the outboard portion of the passageway to interface with the driver hub. The sprocket assembly also includes a bushing to be disposed within the second opening to form a non-torque transmitting interface between the second end of the cassette and the driver hub.

A rotor assembly is provided for an electric motor. The rotor assembly includes: a cylindrical magnet member having magnetization in both axial and radial directions, the magnet member being formed from a moldable magnetic material; and an output shaft receivable within the magnet member. An inner surface of the magnet member and an outer surface of the output shaft have complementarily-engagable interface elements thereon to prevent or limit dislocation of the magnet member and output shaft, and at least one of the interface elements is formed by overmolding of the magnet member and output shaft with the other of magnet member and output shaft.

A gear shaft allows a ceramic bearing to be used in environments where gear steel is desirable for driving a gear. The gear shaft includes a gear region and a bearing region. A bearing can be disposed about the bearing region of the gear shaft. A gear can be disposed about the gear region of the gear shaft. The bearing includes a ceramic material. The gear region of the gear shaft includes gear steel, whereas the bearing region of the gear shaft includes a bearing-region material that has a coefficient of thermal expansion (CTE) that is close to the CTE of the ceramic material.

A planetary gear train of an automatic transmission may include: an input shaft; an output shaft; first to fifth planetary gear sets each including first to third rotation elements, fourth to sixth rotation elements, seventh to ninth rotation elements, tenth to twelfth rotation elements, thirteenth to fifteenth rotational elements; a first shaft connected with the second rotation element and the input shaft; a second shaft connected with the fourteenth rotation element and the output shaft; a third shaft connected with the sixth, seventh and thirteenth rotation elements; a fourth shaft connected with the tenth and fifteenth rotation elements; a fifth shaft connected with the third and fourth rotation elements; a sixth shaft connected with the fifth, eighth, and eleventh rotation elements; a seventh shaft connected with the ninth rotation element; an eighth shaft connected with the first rotation element; and a ninth shaft connected with the twelfth rotation element.
