In this study is proposed to use the fourth class mechanism as an actuator for dairy and fermented milk products plant. Kinematic analysis of the proposed the fourth class mechanism at different configurations relative to rack and the second class mechanism with similar functionality was carried out. Principles of change of analogues of velocity and acceleration of kinematic couples of both mechanisms for an entire work cycle were defined. Comparative analysis of end results was performed. Results of the analysis indicated that the fourth class mechanism allows a considerably better pressure angle. This in return improves dynamic characteristics of the mechanism at similar functionality compared to the second class mechanism. Whereby changing the ratio of the length of couplers in the proposed fourth class mechanism will enable to achieve the desired pressure angle. Link lengths are expressed in dimensionless values easily convertible into metric dimensions. The results of study may be used successfully in designing new vibration machinery with fourth and second class linkage mechanisms used in various branches of industry.
