Abstract

Non-circular gears can be used in modern machines and mechanisms for the implementation of various types of output link movement and have high strength and compactness compared to linkage mechanisms. The article considers the problem of kinetostatic analysis of the planetary mechanism, which provides the rotationally reciprocating motion of the stirred tank impeller. Proposed mechanism is a two-satellite single-row planetary gear with two external gears, in which one pair of gears is elliptical gearwheels. There are constructed calculation schemes, kinetostatic balance equations are compiled and solved for each link of the mechanism. There are found reactions in kinematic pairs and a balancing moment on the input shaft of the mechanism, which are presented as functions of forces on the angle of rotation of the input link. The results can be used in the synthesis, analysis and design of various machines and mechanisms with the proposed kinematic scheme of planetary gear.
