Abstract
The article presents formulas for calculation of normal forces in engagement and additional eccentric at translational motion of satellite wheel. It is shown that the value of normal force in engagement in analytical calculations is the basis for determining its significant geometric parameters. Based on computer studies, it is shown that the number of motion transmitting additional eccentrics should be at least four, and will be determined both from the conditions of contact strength of the contacting links and the geometric parameters of the transmission. Computer models of eccentric transmission at translational motion of satellite wheel have been investigated. Operational parameters of eccentric transmission are obtained, on the basis of which a conclusion is given about a sufficient number of additional eccentrics. On the basis of analytical and computer studies, formulas are proposed for calculating the values of normal forces in the engagement and additional eccentric during translational movement. They can be used to create drive mechanisms that have not only minimal overall dimensions, but also various performance indicators, such as efficiency and kinematic accuracy of the output shaft.
