RV reducers

タイトルまたは説明

RV reducers:

Low machining accuracy • The machining accuracy of RV Reducer parts is required to be micron level. The machining accuracy of domestic reducer is low, the assembly accuracy is low, and the accuracy decreases seriously after use.
Our Solution • Invention of RV Reducer with four cycloidal gears • The mechatronics scheme effectively solves the gradual decline of accuracy • The appearance and installation dimensions remain unchanged 

Low yield• The roundness and diameter of the two eccentric wheels are required to reach the micron level, the hardness is also very high, it is not easy to process, and the error requirement is very low.
Our Solution • Combined eccentric shaft • The product is manufactured separately, which greatly reduces the production difficulty • Greatly improve the yield 

Low operation accuracy • RV Reducer is a pure mechanical component, which does not have position detection function, and its operation accuracy can only be completely dependent on its mechanical accuracy • The mechanical accuracy will decrease after a period of us
Our Solution • Integrated encoder and microcomputer • The closed-loop control of reducer + motor + encoder can realize high precision through software. • The service life of RV Reducer is improved

Low test efficiency• The cost of the test bench is high, and each one is at the level of millions • It is like a large machine tool, weighing about several tons • The installation and alignment of the reducer take a long time
Solution• Invented a special test bench for RV Reducer • Small size, cost less than 10000 yuan • It has been put into production environment

Excessive volume and weight • The smallest rv-6e weighs 4kg and has an outer diameter of 113mm • It can not be used in small manipulators or humanoid robots • Humanoid robots can only use non wear-resistant and vulnerable harmonic reducers
Our Solution • The invention discloses a miniature RV Reducer with a minimum outer diameter of 52mm respectively • It can be used to replace harmonics in small manipulators and humanoid robots, • It is more durable and more accurate than harmonic reducer
