The test period shall not be less than 48 h. 5.2 Bench test requirements 5.2.1 Dynamic sealing performance During the test, the seals shall not have "drops" of oil leakage. 5.2.2 Temperature rise performance During the test, the oil temperature of reducer shall not be greater than the maximum allowable temperature. And the temperature time curve shall be smooth without mutation. 5.2.3 High temperature performance There shall be no oil leakage during the test. And bearings, gears, oil seals and other parts shall not be ablated or damaged to affect the normal operation of the reducer. 5.2.4 Fatigue life After completion of the fatigue life test, the main parts shall not be damaged, connection with the vehicle shall meet the design requirements. 6.1.2 Visually inspect the appearance of the reducer. It shall be free of dirt, corrosion and oxidation. 6.1.3 Check the tightening torque of the bolt with the torsion torque wrench method. 6.1.4 The sealing test shall be carried out in accordance with the airtight or immersion method specified in 6.1.6 of QC/T 29063.1-2011. 6.1.5 Fill lubricants as specified. Start the test bench. Carry out the positive rotation test and the reverse rotation test in sequence. Check whether there is the reducer stuck or abnormal sound. Or test the noise of the reducer under a special test environment with an instrument. 6.1.6 Cleanliness test shall be performed in accordance with QC/T 572, QC/T 573 and QC/T 575. 6.1.7 Salt spray test shall be carried out in accordance with the provisions of GB/T 10125. The exposed area shall not be less than that in the installed state of the vehicle. The duration of the test shall not be less than 48 h. 6.2 Bench test method 6.2.1 The test shall be carried out according to the requirements for bench test of this Standard or purchaser. 6.2.2 Equipment 6.2.2.1 Test equipment The reducer bench test shall have the following equipment. a) drive device in stable operation under the maximum input rotation speed; b) oil temperature and room temperature measurement recorder of continuous recording reducer; c) drive device; d) suction device; e) speed, torque and timer, measurement data logger; f) safety device; g) oil temperature control device; 3) the oil temperature is controlled within 80°C ± 5°C; 4) the test only measures the positive direction; determine in sequence according to the requirements combined with speed, torque, oil temperature. b) Test results. 1) draw a graph of the transmission efficiency speed and the transmission efficiency torque at each test temperature according to the measured results; 2) take the average of all detected transmission efficiencies as reducer’s integrated transmission efficiency; calculate and determine according to equation (1). where, η - the average of transmission efficiency under 2 kinds of torques of 5 test speeds shall be reducer’s integrated transmission efficiency. 6.2.4.6 Differential reliability test a) Test steps. 1) differential grinding-in. any one of the output is fixed not to rotate while the other output can rotate freely; do positive rotation, empty loading; operate for not less than 30 min at an input speed of 2000 r/min ± 10 r/min; replace lubricant after grinding-in is completed; 2) the test shall be c... ......
