According to the technical requirements of precision shafting of inertial navigation test equipment, a comprehensive parameter tester for the rolling bearing is developed. The tester is used to measure the friction torque, bearing stiffness and geometric accuracy in the rotary processing of the rolling bearing and it gives the relations between the friction torque and the axial pre-tightening load, as well as the axial pre-tightening load and the bear axial displacement in the form of a chart or a curve. The system integrates several kinds of sensors and designs hardware control, measuring system and software on a virtual platform. It is characterized by good expandability and lower costs. The system converts control of the best pre-tightening force into control of the bearing bushing height difference, which better solves the best pre-tightening problem in the process of shafting assembly and ensures a stable friction torque for the shafting system. The experiment results show that the system not only finishes all parameter detection successfully, but also can track the variation of frictional torque in bearing running. Under a rotation speed of 8 r/min speed, the rotation friction torque at stable operation is (0.62±0.16) Nm. The experimental data provide theoretical foundation for the control of low rate motion of turntables and the establishment of compensation model for disturbance torques.
