Analysis of influence of eccentricity of seven-channel ball cage constant velocity universal joint on force of steel ball

Abstract

Universal joint is a kind of torque transmission component. Based on the design and working principle of the ball-cage constant speed universal joint, the theoretical calculation formula of circumferential force and normal contact force of the ball of the seven-channel ball-cage constant speed universal joint is established. When the eccentricity of the universal joint is different, the stress of each component inside the universal joint is analyzed. Different input torques of the universal joint were set up and ADAMS multi-body dynamics model was established for simulation. The results show that there is little difference between the theoretical and simulated values of the circumferential force and the normal contact force. With the increase of eccentricity, the force on the steel ball increases, and with the decrease of eccentricity, the force on the steel ball decreases. The eccentricity of universal joint plays an important role in the design of universal joint structure.
