Problems solved by technology

However, according to the current reports, there is no bearing stiffness test device and test method for different angular positions of the rolling elements in the bearing, and the bearing stiffness characteristics at different angular positions of the rolling elements cannot be obtained. Therefore, it is necessary to design a reasonable bearing static Stiffness test device and test method, by determining the precise positioning of the rolling elements in the bearing, to obtain sufficiently accurate stiffness parameter data, to provide a basis for the use of rolling bearings

Description

technical field [0001] The invention belongs to the technical field of rolling bearing measurement, and relates to a bearing static stiffness test device and a test method thereof. Background technique [0002] The static stiffness of rolling bearing refers to the ability of the bearing to resist deformation under static load. As the core component of force bearing and transmission, its stiffness characteristics will directly affect the dynamic characteristics and vibration characteristics of the rotor system. However, the different rotation positions of the rolling elements in the bearing will cause different numbers of loaded rollers in the load-bearing area, resulting in different bearing stiffness. In order to effectively determine the bearing stiffness at different angular positions of the rolling elements, it is necessary to develop Bearing stiffness testing machine. [0003] So far, although experts at home and abroad have proposed some experimental equipment for th...
