Problems solved by technology

[0002] The clearance of the hub bearing is an important index that affects the contact fatigue life, rigidity, friction torque, impact resistance, and fretting wear resistance of the hub bearing. Since the hub bearing has a positive clearance in the finished state, the actual loading is locked by the center bolt Afterwards, it further becomes a negative clearance. At present, there is no corresponding technical solution to measure and obtain the negative clearance level of the wheel hub bearing in the actual loading state

Abstract

The invention discloses a hub bearing working clearance analysis device and method, and relates to the field of hub bearings, the hub bearing working clearance analysis device comprises a first analysis device and a second analysis device, the first analysis device comprises a first tension meter, a gland, a displacement sensor, a supporting seat and a platform, and is used for acquiring a corresponding mathematical relationship among an axial clamping force Fa, an axial clearance S and a raceway friction torque M1 of the hub bearing; and the second analysis device comprises a digital display torque wrench, a reducing sleeve, a center bolt, a wheel bracket and a base, and is used for acquiring a corresponding mathematical relationship between the tightening torque M and the raceway friction torque M2 in the locking process of the hub bearing. The method has the beneficial effects that the relation among the locking torque, the axial clamping force, the axial deformation and the raceway friction torque during hub bearing loading can be well analyzed, and then in the actual hub bearing loading control, in order to guarantee the optimal working clearance of-10 microns to-40 microns of a product, and the corresponding control requirement of the tightening torque of the center bolt is provided.

Description

technical field [0001] The invention relates to the field of hub bearings, in particular to a device and method for analyzing the working clearance of a hub bearing. Background technique [0002] The clearance of the hub bearing is an important index that affects the contact fatigue life, rigidity, friction torque, impact resistance, and fretting wear resistance of the hub bearing. Since the hub bearing has a positive clearance in the finished state, the actual loading is locked by the center bolt Afterwards, it further becomes a negative clearance. At present, there is no corresponding technical solution to measure and obtain the negative clearance level of the wheel hub bearing in the actual loading state. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a hub bearing working clearance analysis device and analysis method to measure, analyze and evaluate the clearance level of the hub bea...
