Research Of The Roller Speed Changing Drive Bearing's Structure Originality Innovation Programmer

The speed changing drive bearing is a new style speed reducer which is improved from the foundation of the havmonic drive and the cycloidal pin wheel planetary gear speed reducer. In any mechanism, the speed.transformation and support parts are necessary, the conventional method is designing the speed.transformation and sustain parts separated, which caused the dimension enlarged of the mechanism. The speed changing drive bearing which combine the speed variator and support parts is a kind of new style mechanism that has the function of speed change and support.This article generalized the classification frame diagram based on the kinds of the oscillating tooth drive, made preliminary exploration of the idea of the structure improvement and put forward the improvement direction of the first.order precision and second heavy.duty explicitly, at last indicated the improvement direction of the first.order transmission was double wave speed changing drive bearing definitely and introduced the composition structure, transmission principle, equivalent system of the double wave speed changing drive bearing; made the analysis of its kinematics and deduced the calculation equation of the freedom, drive ratio, decision manner from the turning of the traction wheel; solved the gear form of the double wave speed changing drive bearing's center wheel and analyzed the element which it effected the transmission performance of the double wave speed changing drive bearing, such as the condition of the double wave speed changing drive bearing's continuous driving, contact ratio and sliding ratio, etc; at last made the force analysis and strength calculation of the double wave speed changing drive bearing.For obtaining the large drive ratio, this article put forward the imagine of the connection in series of the second double wave speed changing drive bearing, and made the theory research of the double wave speed changing drive bearing, the emphasis research is the swing motion second double wave speed changing drive bearing and made the analysis of its structure, then made the calculation of its drive ratio, transmission efficiency, analyzed the rejection of heat of the speed changing drive bearing and put forward the measure to improve the rejection of heat performance of the speed changing drive bearing.The roller havmonic drive is generalized based on the harmonic motion drive, chain.driven and oscillating tooth drive, which solved the fugitiveness question of the flexspline in traditional harmonic motion drive on the structure, at last summarized the imagine that manufacture the speed changing drive bearing without drawing, and made the flow process.
