Определение напряжений в гибком колесе волновой зубчатой передачи

Abstract

To check the flexural strength and endurance of the flexible wheel of a wave gear a method of determining stresses by bending the wheel by a generator of elastic deformations using the theory of thin elastic shells is proposed. The calculated stresses are adjusted taking into account the variable flexural stiffness in the ring gear, and the effect of stress concentration in the valleys between the teeth. It is proposed to determine the stresses in the two dangerous sections - in the valleys between the teeth of the crown and in the area of transition from the ring gearto the flexible wheel. For the second section the calculation of stresses is carried out taking into account the transmission of torque. The example of calculations given in the paper confirms the feasibility of the approach proposed for evaluating the strength and endurance of the flexiblewheel of a wave gear.
