In a standard gear unit, which, in a first variant, is implemented with an output-side bearing and an outgoing shaft, and which, in a second variant, is able to be implemented with an intermediate flange inserted at the bearing position of the output-side bearing, the intermediate flange is formed such that, with an associated, differently formed outgoing shaft, a robot interface or flange block interface is able to be formed on the output side.

A drive system for rotating a wheel of an aircraft landing gear includes a motor operable to rotate a first drive pinion via a first drive path and a driven gear adapted to be fixed to the wheel. The drive system has a first configuration in which the first drive pinion is capable of meshing with the driven gear to permit the motor to drive the driven gear via the first drive path. One of the first drive pinion and the driven gear comprises a first sprocket and the other of the first drive pinion and the driven gear comprises a series of rollers arranged to form a ring. Each roller being rotatable about a roller axis at a fixed distance from an axis of rotation of the first drive pinion or driven gear, respectively.

Provided are: a geared motor with which a large torque can be obtained without an increase in size; and a method for producing said geared motor. In this geared motor (1), an output member (8) having a helical groove (83) formed in an outer circumferential section is provided between a first plate part (31) and a second plate part (32) of a frame (3), and the rotation of a motor pinion (55) is reduced in speed by a reduction gear mechanism (9) and is transmitted to a gear part (85) of the output member (8). In this geared motor (1): the output member (8) is arranged between the first plate part (31) and the second plate part (32); then, a first fixing shaft (35) is inserted from a through hole (37) in the second plate part (32) into a shaft hole (81) in the output member (8), and a first shaft end part (351) is fitted into a first fixing shaft support hole (36); and then, a second shaft end part (352) and the second plate part (32) are fixed.

A motor-gearbox assembly includes a housing, a motor, and a gearbox. The housing includes a first alignment mechanism and a second alignment mechanism. The first alignment mechanism is at a first end of the housing and the second alignment mechanism is at a second end of the housing. The motor is mechanically positioned within the housing in accordance with the first alignment mechanism. The gearbox is mechanically positioned within the housing in accordance with the second alignment mechanisms to mechanically couple to the motor.

A driving apparatus includes a driving input gear with first gear teeth, a columnar shaft, and a driven gear that engages the driving input gear. The driven gear includes a cylindrical boss portion, a cylindrical rim portion, a web, and second gear teeth. The second gear teeth are formed at an outer peripheral surface of the rim portion. The first gear teeth are first helical teeth twisted in a first direction with respect to a direction that the rotary drive shaft extends. The second gear teeth are second helical teeth twisting in a second direction that is the opposite of the first direction. The rim portion is tapered, radially decreasing toward the end to which the web is linked. The through-hole of boss portion has an inner diameter larger than an outer diameter of the shaft.
