Shock absorber bearing load simulation test device

Abstract

The invention discloses a shock absorber bearing load simulation test device, comprising a base, the base is provided with an installation groove for installing the bearing to be tested, the bottom surface of the installation groove is provided with a positioning hole, and the screw on the positioning hole is fitted There is a positioning screw, and the positioning screw is provided with a positioning plate along the circumferential direction, and the positioning plate is in contact with the inner wall step of the outer ring of the bearing to be tested to form the positioning of the bearing to be tested. The end of the positioning screw is connected with a torque meter. A positioning piece for limiting the rotation of the bearing to be tested is also arranged on the base at one side of the installation groove. The simulation test can be effectively carried out on the bearing load of the shock absorber without affecting the measurement of the flatness and position of the inclined surface.

Description

technical field [0001] The invention relates to the technical field of bearing detection, in particular to a shock absorber bearing load simulation test device. Background technique [0002] shock absorber bearings such as figure 1 The shown generally includes an inner ring 6 and an outer ring 5, rollers are arranged between the inner ring 6 and the outer ring 5, a step 51 is arranged on the inner peripheral wall of the outer ring 5, the end face of the outer ring 5 is inclined, and there are also on the outer peripheral wall of the outer ring 51 There is a notch 52 usually provided for auxiliary positioning during installation. During actual use, a certain amount of load will be applied to the inclined surface of the shock absorber bearing. In order to simulate the actual working conditions, the production testing process It is necessary to simulate the load force of the shock absorber bearing. The current detection mostly adopts the method of pressing a heavy object on th...

[0002] shock absorber bearings such as figure 1 The shown generally includes an inner ring 6 and an outer ring 5, rollers are arranged between the inner ring 6 and the outer ring 5, a step 51 is arranged on the inner peripheral wall of the outer ring 5, the end face of the outer ring 5 is inclined, and there are also on the outer peripheral wall of the outer ring 51 There is a notch 52 usually provided for auxiliary positioning during installation. During actual use, a certain amount of load will be applied to the inclined surface of the shock absorber bearing. In order to simulate the actual working conditions, the production testing process It is necessary to simulate the load force of the shock absorber bearing. The current detection mostly adopts the method of pressing a heavy object on the outer ring of the shock absorber bearing to simulate the load situation of the actual working condition. However, in this way, the load on the inclined plane Heavy objects often cover the slope of the shock absorber bearing, which affects the subsequent measurement of the flatness and position of the shock absorber bearing, and the existing detection method is not accurate enough
