Device and method for measuring static characteristics of joint of rolling bearings

Abstract

The invention discloses a device and method for measuring the static characteristics of the joint of rolling bearings, and the device comprises a substrate, and two sides of the substrate are connected with side vertical columns. The side vertical columns are connected with a top plate, and the substrate is provided with a T-shaped groove. The interior of the T-shaped groove is fixedly provided with a first bearing seat and a second bearing seat through T-shaped bolts. A testing shaft is supported and installed in the first bearing seat and the second bearing seat through a first rolling bearing and a second rolling bearing. The interior of the T-shaped groove is also fixedly provided with a support seat through a T-shaped bolt. The support seat is provided with an axial loading assembly which applies an axial force to the testing shaft, and the axial loading assembly is set along the horizontal central line of the first and second rolling bearings. The center of the top plate is provided with a radial loading assembly which is used for applying a radial force to the testing shaft, and the radial loading assembly is set along the vertical central line of the first and second rolling bearings. The device and method can achieve the testing and verification of the static rigidity analysis of the joint of the rolling bearings.

Description

technical field [0001] The invention belongs to the technical field of mechanical structure joints, and in particular relates to a static characteristic measuring device and method for a rolling bearing joint. Background technique [0002] The machine tool is composed of components and the joints between the parts. The machine tool joints, such as rolling bearing joints, bolt joints, etc., contain a variety of nonlinear features. The existence of these complex joints makes it impossible to simply linearly superpose the analysis results of the characteristics of each component in the performance prediction analysis of the machine tool based on the design drawings. It is necessary to establish a model including the characteristics of the nonlinear joint so that the designer can analyze and accurately predict the overall performance of the machine tool. [0003] The rolling bearing joint is a kinematic joint, including the cylindrical surface contact between the inner ring and...
