摘要： A wheel driving device includes a speed reducer for transmitting rotation of an electric motor to a hub ring supporting a vehicle wheel after reducing its speed. The speed reducer is a cycloid speed reducer including an external gear, and an internal gear meshing with the external gear and rotationally fixed to the speed reducer casing through a rotational fixing arrangement which is also capable of elastically supporting the internal gear. The rotational fixing arrangement absorbs, by elastic deformation, vibration of the internal gear due to torque transmitted from the external gear to the internal gear, thereby preventing the vibration of the internal gear from being transmitted to the speed reducer casing.

摘要： A speed reducer includes an internal gear, an input shaft coaxial with the internal gear, and an eccentric disk on the input shaft and rotatable inside the internal gear, and an eccentric disk on the input shaft and rotatable inside the internal gear. A cage at an end of an output shaft, coaxial with the input shaft, and rotatable between the internal gear and the eccentric disk has pockets fewer in number than the internal gear's internal teeth. Rollers are received in the respective pockets such that when the input shaft rotates once, the rollers circumferentially move by a distance equal to one internal tooth width, causing the output shaft to be rotated at a reduced speed. The root radius of the internal gear, the radius of the circumcircle of the rolling bearing, and the outer diameter of the rollers are determined such that roller gaps defined between the rollers and the tooth bottoms of the internal gear are controlled by reduce vibration.
