Embodiment Construction

[0013] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

[0014] Referring to Fig. 1, this embodiment assumes that the hub unit consisting of hub 2, hub bearing 3 and fastening shaft 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 four fixing bolts 7, Set a steel ball positioning groove on the pressure plate 4 which is one wheel radius away from the hub bearing 3, and place the pressed steel ball 5 in the steel ball positioning groove. By replacing the bottom plate and pressure plate, the measurement requirements of different types of hub bearings can be met.

[0015] Two measuring platforms 8 are arranged on the flange plate-shaped base at the lower part of the hub 2 of the hub unit, and the measuring platforms 8 are arranged on the hub 2 at the part of the maximum outer diameter from the bearing 3...

Abstract

The invention relates to bearing measurement technologies, especially to a professional automobile hub bearing rigidity measuring device and method. The device is characterized in that a pressing piece and a support piece in parallel with the pressing piece are designed, the inner ring of a hub bearing is fixed to the support piece in the direction vertical to the pressing piece and the support piece, a space sufficiently high for accommodating the wheel hub as well as the deformation after pressurization of the hub is arranged between the pressing piece and the support piece, each of the pressing piece and the support piece within the maximal hub circumference of the hub bearing is provided with two measurement points, a pressurizing point is arranged in the position whose distance to thecenter of the hub bearing equals the radius of a wheel, data variables after pressurizing are obtained from four measurement points, the deformation angle of the wheel hub in the bearing state is calculated, and the rigidity of the hub bearing is then calculated.

Description

technical field [0001] 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 [0002] 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 [0003] 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 measurement, high p...
