Dynamic performance control method for angular contact bearing

Abstract

The invention discloses a dynamic performance control method for an angular contact bearing. The method comprises the following steps: establishing an angular contact bearing kinetic analysis model considering gyroscopic moment and centrifugal force; establishing an angular contact bearing component heat influence model considering thermal expansion and cold contraction; inputting the rotating speed of the bearing into the analysis model to obtain a numerical relationship between the rotating speed of the bearing and the internal acting force of the bearing; expressing the internal acting force of the bearing by the rotating speed of the bearing and inputting into a control model of the running temperature and the geometric dimension of the bearing, inputting the calculation result into a kinetic analysis model of the angular contact bearing to obtain a kinetic analysis model of the angular contact bearing influenced by the temperature and the speed, and solving the kinetic analysis model to obtain a simulation value; adjusting the bearing operation temperature according to the difference value between the simulation value and the actual kinetic parameter in the bearing operation process, and obtaining the angular contact bearing power performance is obtained. The problem that in the prior art, the dynamics control precision of bearing dynamics is low due to the fact that heating of components in the ball bearing is not considered is solved.
