Embodiment 1

[0049] The testing machine is used for the fretting wear test of workpieces under high temperature and normal pressure water chemical environment.

[0050] see Figure 1 to Figure 5 As shown, the testing machine includes a frame 1, an environmental chamber 2 provided on the frame 1 with an environmental chamber, a fixture 4 for clamping two workpieces and disposed in the environmental chamber of the environmental chamber 2, and a clamp 4 for applying a loading force. The loading device, the testing machine also includes an environment control system for providing the environment cavity of the environment chamber 2 to set the environment.

[0051] see figure 1 , figure 2 As shown, the frame 1 includes a base 11, an upper beam 12 at the top, a column 14 between the base 11 and the upper beam 12, and is vertically set on the column 14 and vertically located between the upper beam 12 and the upper beam 12. The middle beam 13 between the bases 11, on which the environme...

Embodiment 2

[0059] The testing machine is used for the fretting wear test of the workpiece under the environment of high temperature and normal pressure atmosphere.

[0060] see Image 6 , Figure 7 As shown, the difference between the testing machine and the first embodiment mainly lies in the settings of the environmental chamber and the corresponding environmental control system. In this embodiment, the environment chamber adopts the constant temperature atmosphere furnace 3, and the environment cavity of the constant temperature atmosphere furnace 3 is filled with high-temperature gas required for the test. The high temperature and normal pressure gas environment inside the atmosphere constant temperature furnace 3 is controlled by the atmosphere protection constant temperature system.

[0061] The specific structure of this atmosphere constant temperature furnace 3 is referring to Figure 8 to Figure 14 shown.

[0062] The atmosphere constant temperature furnace 3 includ...

Abstract

The invention discloses a high-temperature environment fretting wear testing machine. Specific to the problem that parts are worn and fail due to vibration in the industry field, a set of fretting wear testing equipment which can provide a high-temperature normal-pressure water chemical environment or a high-temperature normal-pressure gas environment and can conduct high-frequency friction with an infinitesimal displacement amplitude is set up, and therefore the friction coefficient and the wear coefficient between parts under the high-temperature environments can be obtained, and a design basis is provided for engineering design.

Description

technical field [0001] The invention relates to a high-temperature environment fretting wear tester. Background technique [0002] The wear between parts in the industrial field often occurs in a high-temperature water chemical environment or a gas environment, and the wear between parts measured on a conventional mechanical testing machine is not used. In the prior art, there is no fretting wear testing machine for high-temperature water chemical environment or high-temperature gas environment in the industrial field. Provide a complete set of test equipment for fretting wear test, friction coefficient and wear coefficient determination. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a high-temperature environment fretting wear tester to provide fretting wear tests in a high-temperature and normal-pressure water chemical environment or a high-temperature and normal-pressure gas env...
