Embodiment 1

[0050] A multifunctional rolling friction and wear testing machine, such as Figure 1-Figure 3 As shown, it includes a kettle body frame 1, a kettle body, a kettle cover 14, a driving device 6, an abrasion device 12 and an air inlet and water inlet device 7; the kettle body is arranged at the lower end of the kettle body frame 1, and the kettle body 14 is arranged on the kettle body The upper end of the frame 1, the kettle body includes a heating furnace 2 and an inner container, the heating furnace 2 is used to heat the inner container, and the kettle cover 14 forms a sealed test chamber with the inner container; the driving device 6 is used to drive the wear device 12, drive the Device 6 is arranged on the kettle cover 14 upper end, and wear device 12 is arranged on the kettle cover 14 lower end; Wear device 12 comprises driving shaft 11 and driven shaft 22, and driving sample ring 20 is set at the driving shaft 11 lower end, and driven shaft 22 lower end The driven sample rin...

Embodiment 2

[0065] This embodiment provides a multi-functional rolling friction and wear testing machine, the structure of which is basically the same as that of the multi-functional rolling friction and wear testing machine provided in Example 1. change, the force applying device 24 also includes a second motor, such as Figure 7 shown.

[0066] Specifically, the second motor is connected with the adjustment screw 27, and the pressure sensor detects the test force applied by the force applying device 24 on the slider 23 in real time, and transmits the collected test force data to the control unit. , both the active sample ring 20 and the driven sample ring 21 are worn, the diameter is reduced, the spring 25 is stretched so that the ejector rod 26 can always be in contact with the slider 23, the compression of the spring 25 becomes smaller, and the pressure sensor detects that the test force becomes smaller , the control unit sends a control command to the second motor, and the second mo...

Embodiment 3

[0069] Cyclic variable speed wear:

[0070] Control the first motor 16 through the program to adjust the speed, such as Figure 4 shown. The output speed of the first motor 16 changes cyclically within a period (T is about 3 to 6 minutes), and the speed (a is about 200 to 600 r / min) starts from zero, increases step by step, reaches the peak value, and then decreases step by step, cyclically Changes to achieve periodic cycle variable wear.

Abstract

The invention discloses a multifunctional rolling friction and wear testing machine, belongs to the technical field of wear testing equipment, and solves the problems that a friction and wear testingmachine in the prior art is single in testing condition and cannot completely meet the friction and wear testing requirements under special working conditions. The testing machine comprises a kettle body rack, a kettle body, a kettle cover, a driving device, an abrasion device and an air and water inlet device, wherein the kettle body comprises a heating furnace and an inner container, and the kettle cover and the inner container form a sealed test chamber; the driving device is arranged at the upper end of the kettle cover, and the abrasion device is arranged at the lower end of the kettle cover; the abrasion device comprises a driving shaft and a driven shaft, a driving sample ring is arranged at the lower end of the driving shaft, a driven sample ring is arranged at the lower end of thedriven shaft, and the driving sample ring drives the driven sample ring to perform rolling friction motion; the air and water inlet device is arranged above the kettle cover and used for adjusting amedium environment in the kettle body. The device meets the requirement of simulating various working conditions in a friction-wear test.

Description

technical field [0001] The invention belongs to the technical field of wear testing equipment, in particular to a multifunctional rolling friction and wear testing machine. Background technique [0002] Friction and wear is a major failure mode in construction machinery. According to incomplete statistics, about 80% of the damaged parts are caused by various forms of wear. Friction and wear are affected by many factors, including temperature, medium, contact force, wear mode, etc. In recent years, with the gradual emphasis on the field of material wear, some researchers at home and abroad have begun to conduct more in-depth research and analysis on friction and wear. [0003] The common friction forms of existing wear testing machines are pin-on-disk, reciprocating, slider, ball-on-disk, rolling-sliding, etc., such as MHK-500 ring-block testing machine, RFT reciprocating testing machine, MM-200 rolling-sliding type testing machine, etc. The above-mentioned testing machin...
