Synthesis and evaluation of non-circular gear that realizes optimal gear ratio for jumping robot
2013 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2013For the effective use of motor power, an appropriate gear ratio has to be selected according to the robot task and motion. Because a jumping robot, in particular, requires both high torque and high velocity properties through the motion, a varying gear ratio is necessary. Moreover, it has to be optimally designed and realized.

KINEMATICS OF ROTATION OF NON-CIRCULAR GEAR WHEELS
REPAIR RECONDITIONING MODERNIZATIONThe study of the kinematics of gears with non-circular gear wheels, including the analytical construction of centroids, the determination of gear ratios and the analysis of the movement of the driven link has been carried out. It is shown how the shape of the centroid affects the dynamics of rotation and can be adapted to specified cycles.
