Title:
DOUBLE-ARC GAPPED MESHING SMALL-TOOTH-DIFFERENCE PLANETARY TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/238075
Kind Code:
A1
Abstract:
Provided is a double-arc gapped meshing small-tooth-difference planetary transmission device, comprising: a box body and an eccentric shaft (1) arranged in the box body, wherein a first eccentric part (2) and a second eccentric part (3) of the eccentric shaft are respectively provided with two outer gears (4); and an inner gear (6) is arranged on the inner wall of the box body corresponding to the outer gear, the inner gear being meshed with the outer gears in a matched mode, a plurality of driving pins (7) being further arranged between the two outer gears, two ends of each driving pin being connected and matched with two end discs (9) to form a planetary carrier structure and output power, the tooth profile of the inner gear and the tooth profile of each outer gear being both arcs, and an initial meshing gap existing between the inner gear and each outer gear. Thus, the problems of complex curve high-precision machining and tooth profile modification are solved, and a good precision operation effect is maintained.
