Calculation of the efficiency of the planetary gear K-V-V without a carrier

Abstract

The work is dedicated to the calculation and improvement of the efficiency of the novel planetary gears without a carrier. The feature of the K-V-V gears is the misalignment of the axles of the driving wheel, the driven wheel and the supporting wheel. Three types of the gearing are considered: 1) involute; 2) involute with the track rollers; 3) articulated. Calculated values of efficiency at characteristic gear ratios are higher than, for example, worm gears, especially for variants with support rollers and gear-hinge gears. The articulated gear (variant 3) is much simpler than the involute gear with the track rollers (variant 2).
