[0002] Oil seal is a mechanical component used to seal oil. Its main function is to prevent the internal liquid from flowing out and the external dirt from entering. Specifically, oil seal is a device that separates the parts that need lubrication from the output parts in the transmission parts to prevent the leakage of lubricating oil. It is widely used in mechanical equipment such as gearboxes and hydraulic cylinders, and is an indispensable part of rotating and moving parts.

[0003] In the oil seal industry, some oil seals need to undergo oil seal durability tests. By simulating the actual working conditions of the oil seals for a long time, we can have a specific understanding of the actual performance of the oil seals.

[0004] When conducting the oil seal durability rotation test, the oil seal will be subjected to various limit tests. At the same time, in the early stage of test equipment assembly, the concentricity of the test chamber and the rotating spindle needs to be corrected. The current one-piece test chamber cannot be adjusted, resulting in the inability to guarantee concentricity. If the concentricity is not adjusted properly, it will affect the test results and lead to poor subsequent processing accuracy. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] The utility model relates to a preferred embodiment of a cavity concentricity adjustment device of an oil seal rotary testing machine.

[0024] See also Figures 2 to 4 The oil seal rotary testing machine cavity concentricity adjustment device comprises a test cavity, which is configured to cooperate with the rotating main shaft.

[0025] The test chamber includes a chamber 1 and linear bearing mounting seats 3 connected to both sides of the chamber 1. The chamber 1 and the linear bearing mounting seats 3 are separately arranged, and the concentricity of the chamber 1 and the rotating spindle can be adjusted by adjusting the position of the linear bearing mounting seats 3.

[0026] In an exemplary embodiment, a linear bearing 4 is installed in the inner cavity of the linear bearing mounting seat 3, and bearing seat fixing seats 2 capable of installing the linear bearing mounting seat 3 are also provided on both sides of the cavity 1, and the linear bearing mounting seat 3 is connected to the side end of the cavity 1 through the bearing seat fixing seats 2.

[0027] Furthermore, the cavity 1 is arranged in a ring shape, and has planar portions 1-1 on both sides of the cavity 1 that cooperate with the bearing seat fixing seat 2. The planar portion 1-1 and the bearing seat fixing seat 2 are provided with mutually cooperating mounting holes 8, and a locking piece is arranged in the mounting hole 8 to achieve a locking connection between the bearing seat fixing seat 2 and the cavity 1.

[0028] Furthermore, the bearing seat fixing seat 2 has an inner concave cavity 2-1, and the linear bearing mounting seat 3 is installed in the inner concave cavity 2-1. Linear pads 7 are provided on the upper and lower sides of the bearing seat fixing seat 2 and the linear bearing mounting seat 3.

[0029] Furthermore, hollow adjustment screws 5 are evenly arranged at the upper and lower ends of the bearing seat fixing seat 2 , and the hollow adjustment screws 5 can move in a direction away from or close to the linear bearing mounting seat 3 .

[0030] The function of the linear pad 7 is to prevent the hollow adjusting screw 5 from damaging the linear bearing mounting seat 3 when adjusting the upper and lower concentricity. Preferably, the linear pad 7 is a copper bar pad.
