Problems solved by technology

However, the design and manufacture of this kind of reducer is complicated, and the processing and installation precision requirements are high. Its core technology is still monopolized by Japanese companies. The country is unable to design and manufacture RV reducers with high precision for robots, and it still mainly relies on imports to meet domestic demand.

Abstract

The invention relates to a novel high-precision reducer for a robot. The novel high-precision reducer is characterized by comprising a housing, an input shaft, an output rotating arm, a center wheel,a planet gear, a crankshaft, a pin gear ring, and outer cycloidal gears, wherein the input shaft and the output rotating arm are coaxially connected in a penetrating manner and supported in the housing; the center wheel is connected with the input shaft in a penetrating manner; the crankshaft is coaxially connected with the output rotating arm in a penetrating manner and supported in the output rotating arm; a straight shaft part of the crankshaft is connected with the output rotating arm in a penetrating manner and is connected with the planet gear correspondingly meshed with the center wheel; an eccentric part of the crankshaft is connected with the pin gear ring in a penetrating manner; a pin gear of the pin gear ring is correspondingly meshed with the two outer cycloidal gears; and thetwo outer cycloidal gears are fixedly connected onto the housing.

Description

technical field [0001] The invention relates to a reducer, in particular to a high-precision reducer for a robot. Background technique [0002] At present, most of the reducers for robots are RV reducers, which are widely used in industrial robots due to their small size, high impact resistance, large torque, high positioning accuracy, small vibration, and large reduction ratio. However, the design and manufacture of this kind of reducer is complicated, and the processing and installation precision are high. Its core technology is still monopolized by Japanese companies. The country is unable to design and manufacture high-precision RV reducers for robots, and it still mainly relies on imports to meet domestic demand. This patent technology proposes a new type of high-precision reducer for robots, which is intended to replace the imported RV reducer and break the foreign monopoly on this technology. The core technology of high-precision reducer for robots with completely ind...
