Embodiment Construction

[0014] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

[0015] see figure 1 In this embodiment, the hub unit consisting of the hub 2, the hub bearing 3 and the fastening pin 6 is fixed on the base 1, and the outer hub of the hub bearing 3 is fixed on the pressure plate 4 through 4 fixing bolts 7, at a distance from the hub A steel ball positioning groove is arranged on the pressure plate 4 at a wheel radius position of the bearing 3, and a steel ball 5 under pressure is placed in the steel ball positioning groove. By replacing the bottom plate and the pressure plate, the measurement requirements of different types of wheel hub bearings can be met.

[0016] Two measuring platforms 8 are arranged on the flange plate-shaped base at the lower part of the wheel hub 2 of the wheel hub unit, and the measuring platforms 8 are arranged on the wheel hub 2 at the posi...

Abstract

The invention relates to a bearing measuring technology, in particular to a device and method for professionally measuring the rigidity of an automotive wheel hub bearing. The method is characterized by comprising the following steps: a pressing part and a supporting part which are parallel to each other are designed; the inner ring of one wheel hub bearing is fixed on the supporting parts along the vertical direction of the pressing parts and the supporting parts; the height for accommodating the wheel hub bearing and an enough space for generating deformation after pressing are formed between the pressing parts and the supporting parts; two measuring points are respectively arranged on the pressing parts and the supporting parts in the maximum wheel hub circumference of the wheel hub bearing; a pressing point is arranged at a position which has the distance of the wheel radius away from the center of the wheel hub bearing; data variables after pressing are obtained from the four measuring points; the deformation angle of the wheel hub bearing under a stress state is calculated; and finally the rigidity of the wheel hub bearing is obtained.

Description

[0001] technical field [0002] The invention relates to bearing measurement technology, in particular to a device and method for professionally measuring the stiffness of automobile hub bearings. Background technique [0003] In the component testing of the manufacturing industry, the accuracy of the testing device is extremely high. When measuring the rigidity of the component, the rigidity of the device itself and the calculation method have a great influence on the measurement data, and sometimes it may not be able to correctly reflect the rigidity of the component under test. In terms of bearing rigidity detection, the main thing is how to measure only the bearing rigidity and be less affected by the rigidity of the measurement system as much as possible. Contents of the invention [0004] The purpose of the present invention is to solve the problem of bearing stiffness measurement, and provide a measuring device with reasonable structure design, convenient measuremen...
