The Design And Dynamic Performance Study Of Servo Drive Gear Train With Reciprocating Rotating Output

Reciprocating rotation is used in many occasions of engineering situations. With the improving of modern industrial automation level and the development of products diversity, lots of new requirements are requested for the reciprocating rotation mechanism. At first it should tend to be controlled with high degree of automation. At same time, the speed and dynamic process should be controlled to meet the needs of product diversification. This paper mainly includes the following three sections.Section one, a double servo drive differential gear train system that could synthesis single-way rotation movement to controllable reciprocating rotation movement is proposed. Its feasibility is verified by some theoretical derivation and software simulation in this thesis. Based on these works, three feasibility mechanism solutions and the equivalent moment of inertia of these mechanisms are formulated. These works supply conference to practical engineering situation for choosing which kind of mechanism is best.Section two, we use the non-circular planetary gear train and non-circular differential gear train to transform the rotation motion of motor into a reciprocating rotation movement. And then, the design method of pitch curve of non-circular gears is proposed and several cases for designing the pitch curve of non-circular are given.Section three, In the thesis, servo-drive gear train with the function of electronic tram is applied in the practical engineering situation. In order to get better dynamic performs; the profile curve of cam is optimized and the servo motor input curve is achieved by using the optimization design so as to get better motor drive method.
