A geared motor, e.g., a gear unit or a bevel gear unit, which is able to be driven by an electric motor, includes a housing part, which is produced by a die casting method, during or after which sliders are moved, in particular pulled out, in respective drawing directions for the demolding, and an input shaft. The housing part includes a channel, demolded in a first drawing direction, in particular, using a first slider, the channel being adapted to extend through the wall of the housing and ending in the interior space region of the gear unit. The drawing direction has a non-vanishing angle in relation to the axis of rotation of the input shaft, its angle in particular amounting to between 5° and 45°, e.g., between 5° and 20°.

A transmission includes an input shaft and an output shaft, the input shaft selectively accepting a torque input from a prime mover, and the output shaft selectively providing torque output to a driveline. A controller determines a shaft displacement angle representing an angle value of rotational displacement difference between at least two shafts of the transmission, and performs a transmission operation responsive to the shaft displacement angle.

A reducer casing structure is disclosed, which comprises a front casing, a rear casing and a connecting column; the front casing and the rear casing are sealedly connected to form therein a cavity structure for accommodating a reducer; the connecting column is provided in the cavity structure and is detachably or partially detachably connected between the front casing and the rear casing, the connection mode of the connecting column with the front casing and the rear casing is bolt connection or integrated casting, the connecting column is used to improve connection strength of the reducer casing structure, reduce casing vibration and improve NVH performance of the reducer. The reducer casing structure according to the present disclosure reduces the deformation of the front casing and the rear casing of the reducer during operation, and improves the NVH of the reducer itself or the whole power assembly; moreover, the reducer casing structure is easy to install and occupies less space.

There is provided a technique capable of increasing support rigidity of a bearing when a support member expands due to moisture absorption. A power transmission device includes: a rotary shaft; a support member disposed outside the rotary shaft in a radial direction; a bearing disposed between the rotary shaft and the support member; and a fitting member fitted to an outer peripheral portion of the support member. The fitting member is made of a material having lower hygroscopicity than hygroscopicity of a material of the support member.

A transmission device for lifting a sickbed is fixed on a head mounting or a bed end of the sickbed and contains: a gear seat, a cover, a power input assembly, and a power output assembly. The gear seat includes a first conduit, a second conduit, a first opening, and a receiving orifice. The cover is covered on the first opening of the gear seat. The power input assembly includes an input shaft and a first bevel gear. The power output assembly includes an output shaft, a second bevel gear, and a support element. The support element is rotatably connected with the output shaft. The support element has multiple reinforcement ribs surrounding around an outer wall of the support element and configured to abut against an abutting fence of the second conduit, and the second bevel gear meshes with the first bevel gear.

A transmission assembly may include a transmission housing; and a receiving space for receiving an electrical functional unit. The receiving space may be formed by at least one wall in the transmission housing and a lid unit, the receiving space may be sealable from an exterior environment via a seal in a contact region on the transmission housing and the lid unit. The lid unit may be connectable to the transmission housing by a screw, where the lid unit includes a channel through which at least part of the screw passes, and where the channel has an inner thread section.

A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing is operationally coupled to the shift actuator and a linear clutch actuator. The linear clutch actuator is a self-adjusting actuator, and the transmission includes a self-adjusting clutch.

A rotation driving device includes: a body 10, made of resin, and having an accommodation hole 13 in a cylindrical shape with an axis S as a center; a motor M, comprising a rotor 60 provided in an accommodation hole of the body and rotating around the axis and a rotation shaft 40 integrally rotating around the axis with the rotor and extending in an axial direction; a first bearing B1 fixed to an end side of the body and a second bearing B2 fixed to the other end side of the body in the axial direction, so as to rotatably support the rotation shaft; and a first cover member 110 connected to the one end side of the body and a second cover member 120 connected to the other end side of the body.
