In order to keep the open circuit state of the series circuit when the sliding column 16 and the bearing 17 to be tested are not in contact, an insulating layer is coated on one end of the upper pressure plate 5 corresponding to the sliding column 16 and the lower end of the sliding column 16 on the test bench 102.

And a loading position for placing the load weight 9 is also arranged on the hydraulic connecting block 8, so that the load is applied to the bearing 17 to be tested through the gravity action of the load weight 9 with the standard weight.

A feedback mechanism for controlling the upper platen 5 to remain horizontal during loading is also included in this embodiment. And as shown in the combination 6, the feedback mechanism comprises two lifting frames 10 which are arranged on the workbench 1 in a sliding manner, and the sliding direction of the lifting frames 10 is parallel to the sliding track of the sliding upright post 16 on the workbench 1 so as to adapt to the measurement of bearings 17 to be measured with different outer diameters. The two lifting frames 10 are respectively provided with second sliding grooves 30 distributed along the respective height direction at the side parts facing the bearing clamping mechanism, second sliding blocks 31 are respectively arranged in the second sliding grooves 30 in a sliding manner, horizontal rods 32 are respectively fixedly arranged on the second sliding blocks 31, and the two horizontal plates respectively extend out of the corresponding second sliding grooves 30 and are inserted into horizontal grooves 11 formed in the upper pressure plate 5. The second sliding chute 30 and the second sliding block 31 are rectangles with corresponding sizes, and fit clearance is fine; the cross sections of the horizontal rod 32 and the horizontal groove 11 are rectangles with corresponding sizes, and the fit clearance is also fine, so that the upper pressure plate 5 is always kept in a horizontal state in the stressed pressing process.

At this time, the upper pressing plate 5 is not installed, loading is not carried out, the sliding upright post 16 slides leftwards by rotating the hand wheel 22 until the pointer of the ammeter 15 swings to generate a reading, namely the right end of the bearing 17 to be measured is in contact with the bottom of the groove 7 clamped by the sliding upright post 16. The first laser rangefinder 21 is struck on the first reflective sticker 18 and records its value.
Then the upper pressing plate 5 is installed, the handwheel 22 is rotated reversely to make the sliding upright post 16 move right to separate from the bearing 17 to be measured, and different loads are loaded on the upper pressing plate 5 through a hydraulic mechanism or loading weights. The sliding upright column 16 is contacted with the bearing 17 to be measured again by rotating the hand wheel 22, the reading of the first laser distance meter 21 is recorded again after the pointer of the ammeter 15 swings, and the b value of the deformation ellipse of the bearing 17 to be measured under the corresponding load can be obtained by the difference between the two readings and the outer diameter value in the factory parameters of the bearing 17 to be measured. In the process of measuring the continuous change of the load, the reading difference of the first laser distance meter 21 can directly reflect the variation condition of the bearing 17 to be measured under the condition of the elliptical deformation under different radial loads, so that the radial bearing capacity condition (radial rigidity) of the bearing 17 to be measured is reflected, and a basis can be provided for selecting the play and the contact angle of the bearing.
Because in the loading process, the second laser range finder 4 is always kept flush with the upper end of the bearing 17 to be measured, the reading of the second laser range finder 4 is directly the a value of the deformation ellipse of the bearing 17 to be measured under the corresponding load. In the measurement of continuous change of load, the reading difference of the second laser distance meter 4 can reflect the variation of a under elliptical deformation of the bearing 17 to be measured under different radial loads. a and b can be detected simultaneously and updated from time to time, so that continuous elliptical deformation conditions of the bearing 17 to be detected under different loads are formed.
