Problems solved by technology

When a single particle invades the relative interface, it is difficult to control its motion state, and there is a problem that the relative force is not easy to control and measure
Therefore, there is no report on the research and test device for the motion state of a specific single particle between the interfaces.

Embodiment Construction

[0022] refer to figure 1 , combine Figure 6 , the test device for single particle intrusion into the opposite interface, mainly including: test bench 1, first three-dimensional displacement mechanism 2, second three-dimensional displacement mechanism 3, clamping mechanism 4, connecting mechanism 5, static interface 6, rotating interface 7, rotating mechanism 8. Single particle 9 and guide rod 10.

[0023] The rotating interface 7 is set on the test bench 1, and the motor in the rotating mechanism 8 is driven by a belt to drive the rotating interface 7. The clamping mechanism 4 is fixed on the first three-dimensional displacement mechanism 2, and the first three-dimensional displacement mechanism 2 is arranged on the test bench 1; the clamping mechanism 4 fixes the static interface 6 so that it contacts the rotating interface 7 at an inclined angle; A three-dimensional displacement mechanism 2 can adjust the three-dimensional position of the clamping mechanism 4 to adjust th...

Abstract

The invention discloses a device for testing single-particle intruding into a relative interface, comprising a test bench (1), a static interface (6), a guide rod (10), a rotating interface (7) arranged on the test bench (1), a connecting mechanism (5), a clamping mechanism (4) fixedly connected with the static interface (6) and a rotating mechanism (8) driving the rotating interface (7). The clamping mechanism (4) is fixedly connected with the static interface (6) and enables the static interface (6) to contact with the rotating interface (7) in an inclination angle; one end of the guide rod (10) is connected with the connecting mechanism (5) through a bearing, and the other end is fixed in the center of a single particle (9) in a penetrating way; the single particle (9) is arranged in the inclination angle; the guide rod (10) is parallel to the rotating interface (7) and points to the rotating center of the rotating interface (7); the clamping mechanism (4) is provided with a first transducer; and the connecting mechanism (5) is provided with a second transducer and a third transducer.

Description

technical field [0001] The invention relates to the research field of three-body friction and wear, in particular to a test device for single particle intrusion into opposite interfaces, which is suitable for the research of friction and wear between contact interfaces. Background technique [0002] All kinds of machinery, especially precision instruments, require good contact between the interfaces of various mechanisms or seals. Once sand and dust particles in the working environment invade between the interfaces, it will aggravate wear and energy consumption, making the mechanism or instrument very difficult. Fast to fail. Professor H.P.Jost of the United Kingdom pointed out that 30%-40% of the world's energy consumption is lost in friction and wear; in my country in the 1980s, the incomplete statistics of five departments such as metallurgy, coal and agriculture, only abrasive particles One million tons of spare parts steel is consumed in wear and tear, and the annual ec...
