Embodiment 1
[0042] refer to Figure 1 ~ Figure 3, in this embodiment, a double-row angular contact ball bearing axial clearance measurement device is proposed, which is used to measure the axial clearance of double-row angular contact ball bearings. The double-row angular contact ball bearing shaft The device for measuring the backlash includes: a worktable 1, a working disk 11, a driving disk, a motor 19, a pressure sensor, a distance measuring sensor 6 and a controller.
[0043] The workbench 1 is used for support and installation. The workbench 1 can be a horizontal plate structure. The four corners of the bottom of the workbench 1 are provided with support legs. The bottom of the support legs can be fixedly connected with a backing plate. The support legs support the workbench 1 to the specified height. The four corners of the workbench 1 may be equipped with universal wheels, and clamping plates for braking are arranged on the universal wheels, so as to facilitate the movement and f...
Embodiment 2
[0053] refer to Figure 7 , in this embodiment, a method for measuring the axial clearance of a double row angular contact ball bearing is proposed, which includes the following steps:
[0054] S1. The bearing 10 inside the feeding barrel 21 enters the placement groove 12 of the feeding station.
[0055] S2. The rotating drive part drives the working disk 11 to rotate intermittently, and the bearing 10 enters the detection station.
[0056] S3. The telescopic driving part 3 drives the pressing part 9 to descend and press the bearing 10 .
[0057] S4. Obtain the pressure F sensed by the pressure sensor and the stroke distance L sensed by the distance measuring sensor 6 .
[0058] S5. Judging whether the travel distance L is greater than a preset L 标 , if yes, execute S6.
[0059] S6. Sending a first alarm signal.
[0060] S7, judging whether L / (F-G) is greater than a preset θ 标 , if yes, execute S8.
[0061] S8. Sending a second alarm signal.

Abstract
The invention relates to the technical field of detection, and particularly discloses a double-row angular contact ball bearing axial clearance measuring device and method, and the device comprises a workbench,a working disc, a rotation driving part, a feeding barrel, a supporting frame , a telescopic driving piece , a pressure sensor, a distance measuring sensor, and a controller . The working disc is rotationally connected to the working table, and a plurality of containing grooves are evenly formed in the working disc in the circumferential direction. And the rotation driving part is used for driving the working disc to rotate intermittently. The feeding barrel is fixedly installed on the workbench and located at the feeding station. The supporting frame is fixedly installed on the workbench, and the pressing piece is connected to the supporting frame in a lifting mode. And the telescopic driving piece is mounted on the supporting frame and connected with the pressing piece. And the pressure sensor is mounted on the pressing piece. And the distance measuring sensor is mounted on the supporting frame. And the controller is connected with the pressure sensor, the distance measuring sensor, the telescopic driving piece and the rotating driving piece. According to the method, characterization is carried out through the axial clearance distance and the ratio of the clearance to the extrusion force, the characterization capacity is high, and the axial clearance of a bearing can be better analyzed.
Description
technical field [0001] The invention relates to the technical field of detection, in particular to a measuring device and method for the axial clearance of a double row angular contact ball bearing. Background technique [0002] With the development of aero-engines, double-row angular contact ball bearings are used more and more widely, and can have a larger load-carrying capacity while saving installation space. It can withstand radial load and axial load in two directions, and has strong bending moment resistance. [0003] The axial clearance of double-row angular contact ball bearings is a key indicator affecting the load of the two-row bearings. However, since the clamping of this type of bearing and the degree of clamping have a large impact on the axial clearance of the bearing, the axial clearance of this type of bearing The consistency of clearance measurement is poor and cannot meet the requirements of use. Generally, the axial clearance of double-row angular cont...
