Parametric analysis of device for the mixing with the equal angles overlap and pressure

In this paper a problem is concerned parametric synthesis of lever, spatial, rocker and offset mechanism, it is used in mixing substances. Rational dimensions of mechanismspsila links are defined such that contact angle is equal to overlap ones in according to recommend value. Function is defined general solutions of lay down conditions, it is allow to define linkpsilas length of mechanism relatively given dimension of mechanismspsila frame. It is shown that in the rocker-mechanisms contact angle is equal to overlap ones in case of yoke- offset larger than crank.
