Studies related to increasing the efficiency of new planetary gear designs with intermediate rolling bodies, balls and rollers of tire wearing surface with higher kinematic and dynamic characteristics are presented. The most effective way to increase the efficiency of these gears is to optimize the geometrics of engagement parts, which include lifting angles, amplitude and average radius of tire wearing surface. A technique is developed and mathematical dependencies are obtained that allow determining the optimal geometrics of planetary ball and roller gears to increase their efficiency. The power losses at lifting angles of tire wearing surface providing the highest transmission efficiency are calculated for each link of the studied planetary gears constructed according to a single kinematic scheme. The dependences of power losses of planetary ball and roller gears on lifting angles of the leading tire wearing surface are obtained. The highest values of transmission efficiency are determined depending on the optimal lifting angles of the leading tire wearing surface and the gear ratio. The optimal values of average tire wearing surface radius and amplitude are found out, and their best ratios are obtained, ensuring the highest transmission efficiency. The calculation results of geometrics providing the highest efficiency of new planetary ball and roller gear designs are presented.
