Document Type and Number:
WIPO Patent Application WO/2021/112466
Kind Code:
A1
Abstract:
The present invention relates to a speed reducer for decelerating rotational force transmitted from a power unit, and, more specifically, to an eccentric speed reducer that presents a method in which first and second gears having different numbers of gear teeth are engaged with each other so as to rotate relative to each other by the rotational force transmitted through an input shaft, and thus a high reduction ratio and a large output can be generated with only a simple structure and, furthermore, outputs having different reduction ratios are simultaneously generated through a single input shaft.
