Abstract

The invention discloses a device for detecting the axial force of a hub and the displacement of a bearing in real time by applying torque. The device comprises a rack and is characterized in that a force bearing seat, a supporting seat, a process monitoring instrument mounting bracket, a tension and compression sensor, a transition sleeve, a guide sleeve seat, a guide sleeve, an ejector rod, a supporting seat, a spacer bush, a shaft head, a measuring disc, an inner displacement sensor, an outer displacement sensor, a sensor mounting bracket, a shaft head nut and a monitoring instrument are arranged on the table surface of the rack. According to the device, the magnitude of axial force generated under different torques and data of axial displacement generated by a bearing under the action of the axial force are detected in real time by applying the torques; and rough assembly process parameters are formulated according to actual measurement data and experimental verification is carried out, and reasonable process parameters are determined according to experimental results, so that the hub assembly quality is guaranteed, and the labor intensity of operators is reduced.

Description

technical field [0001] The invention relates to the field of assembly technology, specifically a device for real-time detection of hub axial force and bearing displacement by applying torque; Deformation detection; through the quantitative detection of axial force, provide data support for the reliability of the assembly connection; generate axial force through the torque of the nut, so that both the inner and outer bearings have an axial displacement, and detect the change of the axial displacement of the bearing, Ensure the reasonableness of the bearing assembly clearance. Background technique [0002] The wheel hub is an important part of the car driving system. It is used to install the car tires. There are two cone bearings inside the wheel hub. The wheel hub is set on the axle head of the axle housing through the cone bearings. The car is finally supported and driven by the tires installed on the wheel hub. The working environment of the wheel hub is very bad. To ensu...
