Abstract

A two-stage differential cycloidal speed reducer with a high reduction ratio is provided, including: a plurality of supporting crank shafts; an input shaft including a first crank shaft portion and a second crank shaft portion; a first cycloidal gear provided on the first crank shaft portion; a second cycloidal gear provided on the second crank shaft portion and connected with the first cycloidal gear through the supporting crank shafts; a plurality of first ring pins provided around the outer circumference of the first cycloidal gear and in sliding contact with a plurality of teeth on the periphery of the first cycloidal gear; a first annular gear with the plurality of first ring pins; a plurality of second ring pins provided around the outer circumference of the second cycloidal gear and being in sliding contact with a plurality of teeth on the periphery of the second cycloidal gear; and a second annular gear with the plurality of second ring pins.

Description

technical field [0001] The invention relates to a speed reducer, in particular to a cycloid speed reducer with two stages of differential speed and high reduction ratio. Background technique [0002] The reducer is a power transmission mechanism that uses gears to reduce the speed of the motor to the desired speed and obtain a larger torque. In the mechanism currently used to transmit power and motion, the application range of the reducer is quite wide, from ships, automobiles and motorcycles, heavy machinery for construction, processing machinery and automatic production equipment used in the machinery industry, to daily life. Common home appliances, clocks and watches, etc., can be seen in the application of reducers from the transmission of large power to the transmission of small loads and precise angles. [0003] The reducers currently used in robots mainly include gear reducers, harmonic reducers (HarmonicDrive), RV reducers, and cycloid reducers. Harmonic Drive main...
