| 7. Sizes of specimen: 03O-5Ox1Omm 8. The max. stroke of the upper specimen: ±4mm. 9. Power of motor:3 phases, 380V, 50Hz. 1Kw, 0.75Kw. Speed: 2870r/min, 1440r/min. 10. Dimensions: 970x660x1100mm 11. Net weight: About 500kg The machine calculate friction work and also friction coefficient by the data acquired. Wearable function evaluated: The following methods to evaluate the wearable function. 1. Weight: Before test, make the specimen clean and dry. After test, by means of analytical balance, to measure the difference of the specimens 2. Diameter measuring: Measure the variety of the diameter after test. Measuring instrument: 1. micrometer. 2. By the small idler wheel in the machine. 3.cut-in method. |
