Title:
REDUCER
Document Type and Number:
WIPO Patent Application WO/2019/212001
Kind Code:
A1
Abstract:
[Problem] To provide a reducer which is capable of exerting the same function as that of a ball reducer, and has a simple structure, and in which the number of components is small and the number of assembly steps can be reduced. [Solution] A reducer 1 is provided with: an eccentric cam 3 that rotates integratedly with a drive shaft 2; oscillating bodies 4 that are oscillated by the eccentric cam 3; a fixation member 5 which is disposed so as to face one lateral surface side of each of the oscillating bodies 4; and an output-side rotating body 6 which is disposed so as to face the other lateral surface side of each of the oscillating bodies 4 and which rotates relatively with respect to the fixation member 5. In the oscillating bodies 4, oscillating parts 17 are formed integrally with leading ends of arm parts 16 which are elastically deformable. A first truncated cone-shaped portion 17a of each of the oscillating parts 17 is radially guided through a radial groove 20 in the output-side rotating body 6, and a second truncated cone-shaped portion 17b of each of the oscillating parts 17 is guided, in a wave shape along the circumferential direction, through an annular wave-shaped groove 21 in the fixation member 5. Each of the oscillating bodies 4 and the output-side rotating body 6 are coupled by means of a rotary coupling means K so as to rotate together.
