test equipment

1. The transmission system is used to drive the ring to rotate at a given speed, accurate to within 5%, and requires the radial runout of the shaft at the installation location of the ring to be less than 0.01 millimeters.

2. Loading system, can apply normal force to the sample and ring, accurate to within 5%.

3. Measure and record the friction torque system with an accuracy of within 5%.

4. A counter or timer that records the number of revolutions of a circular ring, accurate to within 1%.

5. The structure and dimensions of the sample fixture are shown in Figure 2, and are equipped with washers 4 GB 848-76 and countersunk screws M3 ? 0.35, which are 10 millimeters long. Ensure that there is no axial movement after the sample is placed.

Note: This standard recommends using the M-200 wear testing machine for testing equipment.

6. The material of the circular ring in this experiment has a significant impact on the results of the plastic wear test. Therefore, the circular ring used in this standard has its external dimensions shown in Figure 3.

The material is 45 steel, and the circular ring requires overall quenching and heat treatment with HRC 40-45. The surface smoothness of the outer circle is ▽ 8, and the chamfers are all 0.5 ? 45 degrees. The concentricity deviation between the outer and inner circles is less than 0.01

The circular ring can be reused and needs to be re ground after each test. When the outer diameter is less than 36 millimeters, it cannot be used again. When conducting arbitration tests, a circular ring with a diameter of 40 millimeters must be used.

Note: The material of the circular ring can also be determined separately according to product standards.

試驗步驟

1、圓環應清除油污，貯存于干燥缸內以防生銹。

2、試樣經狀態調節后用感量為0.1毫克的分析天平稱取其質量（M1）。

3、把試樣裝進夾具，摩擦面用角尺校正并使它與圓環的交線外于試樣正中。裝好摩擦力矩記錄紙，開機校好零點。

4、再次用乙醇、丙酮等不與塑料起作用的溶劑仔細清除試樣和圓環上的油污，此后不準再用手接觸試樣和圓環的表面。

5、平穩地加荷至選定的負荷值。

6、對磨2小時后停機卸負荷，取下試樣和圓環，清理試樣表面后，用精度不低于0.02毫米的量具測量磨痕寬度，或在試驗環境下存放1小時后稱取試樣質量（m2)。

7、讀取摩擦力矩值。

Experimental steps

1. The circular ring should be cleaned of oil stains and stored in a drying cylinder to prevent rusting.

2. After adjusting the state of the sample, weigh its mass (M1) using an analytical balance with a sensitivity of 0.1 milligrams.

3. Insert the sample into the fixture, calibrate the friction surface with an angle ruler, and ensure that its intersection with the circular ring is outside the center of the sample. Install the friction torque recording paper and start the machine to calibrate the zero point.

4. Carefully remove the oil stains on the sample and the ring using solvents such as ethanol and acetone that do not work with plastic. After that, do not touch the surface of the sample and ring with your hands.

5. Smoothly load to the selected load value.

6. After grinding for 2 hours, stop the machine to unload the load, remove the sample and ring, clean the surface of the sample, measure the width of the grinding mark with a measuring tool with an accuracy of not less than 0.02 millimeters, or weigh the sample mass (m2) after storing it in the test environment for 1 hour.

7. Read the torque value of friction force.
