Design of elliptic crank slider intermittent mechanism

Abstract

This thesis elliptic crank is a capable of generating elliptic curve of planetary bodies and elliptic slider crank mechanism is slider crank mechanism is a kind of special mechanism, but it can change crank length and speed to change the movement characteristics of the slider. In this paper, we also study the characteristic of the approximate interval of the slider with the elliptic crank mechanism in the limit position.

In this design, the research on the elliptic crank slider intermittent mechanism is carried out, and an example is used to simulate the elliptic crank slider mechanism. A method for adjusting the interval range is proposed. Finally, a case is given. In the whole process of learning to a number of institutional design knowledge and the deepening of school knowledge, my ability to scientific research has been greatly improved.
