Title:
TRANSMISSION MECHANISM
Document Type and Number:
WIPO Patent Application WO/2021/166539
Kind Code:
A1
Abstract:
The present invention provides a transmission mechanism that enables a reduction in motion transmission error between an input-shaft side and an output-shaft side. A transmission mechanism (101) is provided with a cam (102), a plurality of pins (105) arranged along a side surface (103) of the cam, guide plates (107a, 107b) in which a plurality of guide holes (109a, 109b) are provided, and gears (106a, 106b) capable of engaging the pins. In conjunction with rotation of the cam, each pin is guided by the corresponding guide hole (109a, 109b) and moves along the cam and the gears, thereby causing the guide plates or gears to rotate relative to the cam. The plurality of pins (105) are divided into a plurality of groups (110a-110f), and the pins (105) in each group (110a-110f) are coupled in series, but are not coupled to the pins (105) in the other groups (110a-110f).
