A switch power generating mechanism includes at least a first movable component, a second movable component, a first deforming component connected to the first movable component, and a power generator, wherein a pressing force is transmitted to the second movable component from the outside of the switch power generating mechanism to cause at least part of the first movable component and at least part of the second movable component to move in a connected manner and cause the first movable component to rotate by a fixed amount to deform the first deforming component by a fixed amount; and the deformation of the first deforming component is released once the first movable component has been caused to rotate by the fixed amount, and power generation is performed with power generated in the power generator due to the first movable component rotated by a fixed amount with the release from the deformation.

The invention relates to an angle geared motor and to a method for setting a defined play between a pinion (17) and a gear. The angle geared motor has a gearbox housing, in which a gear is rotatably mounted, a gearbox-side motor end shield (4), through which a motor shaft (16) having a pinion (17) fastened thereto extends, an interface between the gearbox housing (11) and the gearbox-side motor end shield (4), and a pin (15), which is fastened in the motor end shield (4) and which serves as a pivot point for the rotation of the gearbox housing relative to the motor end shield (4).

An electric motor includes a front end cover, a rotary output shaft extending through the front end cover from an inner cavity of the electric motor, and a gear transmission mechanism provided inside the inner cavity of the electric motor. The rotary output shaft includes an inner rotary shaft and an outer rotary shaft that are arranged concentrically. The gear transmission is in a transmission connection with the inner rotary shaft and the outer rotary shaft.

A type series of gear-side motor end shields for an angle geared motor is disclosed, with the angle geared motor including a gear housing of an angle gear, in which a toothed wheel is mounted to rotate about a gear shaft axle, and a stator housing of an electric motor, in which stator housing a motor shaft is rotatably mounted. Each of the gear-side motor end shields includes a gear-side section for securement of the gear housing, and a motor-side section which is permanently connected to the gear-side section for securement of the stator housing. The gear-side motor end shields are configured such that each of the gear-side motor end shields produces a different axial offset between the gear shaft axle and an axle of the motor shaft.

An electric motor equipped with a transmission unit in the form of a planetary gear transmission is provided. The planetary gear transmission has a sun gear, planetary gears, and a ring gear, which are coupled to one another via corresponding toothings. The sun gear is coupled directly to a shaft of the electric motor and is fastened thereto. The planetary gears or axles thereof are retained on a bearing plate of the electric motor. The ring gear is rotatably mounted on the housing of the electric motor or is fastened to the housing of the electric motor. A common feature is that parts of the transmission are retained on the housing of the electric motor and not on a separate housing or another component of the transmission unit.
