Bending Stress Analysis of Idle Gear with Thin Rim : Effect of Rim Thickness on Stresses

抄録

Stress distributions in planet gears with a thin rim are analyzed by the photoelastic method and the following results are obtained: Although the position of the maximum stress occurring on a fillet varies with both the tooth load and the radial clearance between rim and gear shaft, it may be sufficient to consider the maximum tensile and compressive fillet stresses in the planet gear concerning the bending strength. In the case of a thin rim, if the radial clearance increases by more than a certain value, the stress amplitude on a fillet may increase rapidly and the value of the clearance may decrease when the rim thickness decreases.
