Abstract

The invention discloses a joint bearing rigidity test device and a test method. The joint bearing rigidity test device comprises a test box body, a joint bearing seat, a main shaft, a locking nut, a loading device and a sensor, other parts are arranged in the test box body, an outer ring of a tested joint bearing is arranged in the joint bearing seat, the main shaft is sleeved with an inner ring,and a shaft shoulder axially depending on the main shaft is fixed with the locking nut; at a left end of the main shaft, a flange plate is externally arranged at a left end surface of the test box body, the right end of the main shaft is fixed with the right end surface of the test box body through a bolt; the loading device is used for applying axial and radial load on the tested joint bearing, the sensor is used for testing the displacement and load of the tested joint bearing. The joint bearing rigidity test device provided by the invention has the advantages of being simple in structure and convenient to assemble and disassemble, and can be used for performing accurate radial loading and accurate axial loading of the joint bearing, the tested joint bearing rigidity parameter is accurate and reliable, and the device is suitable for the performance measurement of the joint bearing development organization and using organization.

Description

technical field [0001] The invention relates to a joint bearing measuring device, in particular to a joint bearing stiffness test device and a test method. Background technique [0002] Spherical joint bearing has the characteristics of bearing radial load and axial load, and can rotate and swing at any angle during motion. Its stiffness characteristics directly affect the mechanical characteristics of mechanical equipment, especially the dynamic characteristics. It is one of the key components in the swing mechanism device. one. It is of great significance to reasonably determine the stiffness characteristics of spherical plain bearings, especially to obtain accurate stiffness parameters of spherical plain bearings through experimental tests, for the development and use of key bearings and swing mechanism devices. [0003] So far, there have been some experimental equipment for performance measurement and research of joint bearings such as lubrication and fatigue, such as:...

AI Technical Summary

Problems solved by technology

However, compared with rolling bearings, joint bearings have a swing function, and rolling bearings have a rotation function, so there are big differences in structure and function.
