Description
Technical field
It the utility model is related to a kind of decelerator field, more particularly to a kind of accuracy of manufacture requires relatively low has bullet
Property compensation pin tooth cycloidal reducer.
Background technology
The transmission device that pin tooth cycloidal reducer has been widely used as industrial robot at present is applied.Especially subtracted with RV types
Fast device for representative pin tooth cycloidal reducer so that its is compact-sized, transmission capacity is strong, turn into the most important part of robot system.
It refer to shown in Fig. 1, RV type pin teeth cycloidal reducer is mainly included positioned at middle to connect servomotor（It is not shown）It is defeated

Commonplace existing common fault.The new machine precision just assembled is good, and using soon, precision is substantially reduced, and lubricating oil is sent out rapidly
Black, precision is kept for the life-span too short, and this is far from meeting require that for robot.
To solve this awkward situation, the major measure that the country is taken at present is further raising machining accuracy, is striven for comprehensively
Drawn close to import is original-pack.And carry process equipment of the high-precision major measure using higher level, mainly import.It is but true
Prove, purpose can not be fully achieved merely by so doing, and the production cost thus brought is expensive, also makes one to suspect that future can not
The real commercialization of energy, so as to reach the ability with external product competition.
