1. A gear housing consist of
a drive shaft rotatably positioned within the gear housing;
an output gear rotatably positioned within the gear housing;
a gear mechanism positioned between the drive shaft and the output gear to provide functional connection between them, wherein the gear mechanism is located between the drive shaft and the output gear and designed to perform a bending motion upon rotation of the drive shaft, comprising an wobbled member and wherein the wobbled member is connected to the output gear in such a way that the bending motion of the wobbled member is converted into rotational motion of the output gear, constituting a transmission, and characterized by including:
a first gear wheel and a second gear wheel rotatably positioned within the gear housing and connected to the output gear, wherein the first gear wheel and the second gear wheel are each connected to at least one gear wheel idle pulley, and the gear wheel idle pulleys will be rotatable in a relative freewheeling direction with respect to the first and second gears, and in a locking direction, they are designed to be locked against a relative rotational movement of the respective gear wheel;
a tilted wobble plate mounted on the drive shaft and carrying the wobbled member, wherein the tilted wobble plate is mounted rotatably within the wobbled member and is mounted to rotate together with the drive shaft about the axis of rotation of the tilted wobble plate, and here, the tilted wobble plate has an adjustable inclination angle relative to the axis of rotation of the tilted wobble plate, thereby allowing the tilted wobble plate to perform a bending motion relative to the axis of rotation of the tilted wobble plate while the drive shaft rotates, and causing the wobbled member to also undergo a bending motion through a bearing connecting the tilted wobble plate to the wobbled member;
wherein the wobbled member is connected to the gear wheel idle pulleys, such that the bending motion performed by the wobbled member is converted into back-and-forth rotational motion of the gear wheel idle pulleys, and is connected in a manner such that the driving force transmitted to the drive shaft is transferred to the output gear, ensuring the conversion of the driving force to the output gear in response to the back-and-forth rotational motion of the gear wheel idle pulleys;
additionally, control command devices are provided here to adjust the inclination angle at which the tilted wobble plate stands relative to the axis of rotation of the tilted wobble plate.
