The Dynamic Characteristics of the Torque Sensor by Bearing Interference Fit

Abstract

Taking high-speed dynamic torque sensor shaft with an interference fit bearing whose effect is on the dynamic characteristics of the sensor shaft as the research content. It introduces a analysis of the bearing fit interference quantity model of the impact of the bearing contact angle. It is focused on dealing with the fit tolerance between inner ring of bearing and shaft as well as outer ring of bearing and bearing seat taking 7004C as an example. Bearing interference fit of the equivalent model is established based on the theory of thick wall cylinder, and then it is verified by the Ansys Workbench simulation results.
