Position analysis of minimum transmission angle of idle stroke in crank-rocker mechanism;

Analytical method for designing crank-rocker mechanism according to minimum transmission angle;

This paper is disscussing a new method which is used to determine the position and dimension of minimum transmission angle of plane Crank-and-Rocker mechanism with Time Ration(k=1&k≠1).

The article bases on the traditional graphical method,and applies design principle in the references[1],derives the optimizing design methods which under the condition of meeting the fixed slider stroke and the coefficient of variety of stroke velocity,makes the minimum transmission angle of the eccentric crank slider mechanism to maximum(that is the best transmission angle).

According to its equivalent mechanism—crank rocker mechanism, driving performance and minimum driving angle position of movable tooth is analyzed.

Given the stroke speed ratio factor K of the quadric crank mechanism and the position of the two poles of the actuating driven member, using the minimum driving angle as the objective, the type and size of the quadric crank mechanism are determined with optimistic technology.

With the assistance of computer coded program, this paper, by means of geographically analysing crank and rocker mechanism, helps readers to find out a center point, at which the biggest minimum driving angle is.
