Power calculation of a coupled mechanism of parallel cranks

Design and layout capabilities of gearboxes with flexible and rigid links created on the basis of dual mechanisms of parallel cranks (wave gears with external deformation wave generators of the crank-planetary gearboxes and combined planetary-wave mechanisms) most fully satisfy requirements to the transmission mechanisms of the system automatic control of the antenna drives. Methods for calculating geometric characteristics, power interaction of elements, evaluation of the main quality indicators of the wave gear with external deformation wave generators and recommendations for their use are practically missing in the technical literature (except for works of scientists from the Department of Theory of Mechanisms and Machines, Bauman Moscow State Technical University). Therefore, studies aimed at creating methods of calculating and designing these mechanisms for special drives of the automatic control systems are important. The paper describes technique of power calculation of the double mechanism of the wave gear parallel cranks with the wave external deformation generator making it possible to competently design these drives.
