Embodiment Construction

[0028]The invention relates to an axial load testing method for ball bearings. The axial load testing method uses a set of testing devices to install and position the tested ball bearing and realize the tested ball bearing. The ball bearing applies a stable and non-impact axial load, and the compressed air in the airtight air chamber can realize the constant speed of the air spindle and make the ball bearing under test realize the stepless loading axial load. The axial load test method is reliable, simple to operate, The method is simple.

[0029] combine figure 1 , the test device includes a locking nut 1, an adjusting nut 2, a cylinder 3, an end cover 4, a base 5, an axial drag frame 6, an air spindle 7, a bearing sleeve 8, a positioning centering seat 9, and a positioning support 11, wherein The effective cross-sectional area of ​​the air spindle 7 in the case of a given outer diameter is represented by S, and the air spindle 7 is re-measured and used W when the outer diam...

Abstract

Disclosed is an axial load testing method of a ball bearing. According to the axial load testing method of the ball bearing, the ball bearing (10) to be tested is sleeved on a positioning footstock (9) and located at the lower end of a positioning support (11), the upper end of an air spindle (7) is connected with the positioning footstock (9), the lower end of the an air spindle (7) is connected with an axial rack (6) and a cylinder (3), the cylinder (3) is provided with an adjusting nut (2) and a locking nut (1), a base (5) is provided with an air inlet (5.1), an air discharge outlet (5.2), a via hole (5.3), a bearing sleeve (8) and an end cover (4), compressed air with pressure of P1 or P is introduced to an airtight air chamber formed by the base and the like through the via hole to enable the air spindle to rotate easily in a friction free state, and the compressed air in the airtight air chamber enables upward floating at a constant speed of the air spindle to be achieved and enables stepless loading of an axial load of the ball bearing to be test to be achieved by applying the steady and shock-free axial load to the ball bearing to be tested with pressure P; and the axial load of the ball to be tested is F=P*S-W1-W2-W3-W4. The axial load testing method of the ball bearing is reliable, and simple in operation.

Description

technical field [0001] The invention belongs to the technical field of bearings, and particularly relates to an axial load testing method of a ball bearing. Background technique [0002] Both deep groove ball bearings and angular contact ball bearings can be called ball bearings. In many occasions, the axial load of the ball bearing needs to be tested to ensure the stability and repeatability of the ball bearing. [0003] There are usually the following ways to test the axial load of ball bearings: [0004] 1. Use a fixed weight to load and test the axial load of the ball bearing; [0005] 2. Use a combination of fixed weights and levers to load and test the axial load of the ball bearing; [0006] 3. Use hydraulic loading method to test the axial load of the ball bearing; [0007] 4. The axial load of the ball bearing is tested by pneumatic loading. [0008] The above four methods have the following problems: [0009] During the test, the added axial load is required t...
