7.3.1. The load test is carried out after passing the no-load test. At the rated speed, the load is remotely loaded in four stages of 25%, 50%, 75% and 100% of the rated input power. The operating time of each stage is stabilized by the temperature rise of the lubricating oil. shall prevail, but shall not be less than 2h. 7.3.2 During the load test, for products that require reversing operation, tests should be conducted in forward and reverse directions. For products that work in one direction, only one-way tests are allowed, but the rotation direction during the test must be consistent with the working direction. 7.3.3 The load test shall meet the following requirements. Under rated speed and rated load, the temperature rise of the oil pool of the test device shall not exceed 45°C, and the maximum temperature shall not exceed 85°C, and shall comply with the provisions of Articles 5.5, 5.6, and 5.7 of this standard. . 7.3.4 After the temperature rise stabilizes, take 10 sets of speed and torque data from the input end and output end of the variable speed bearing under test at the same time and input them into the computer at the same time to calculate the transmission efficiency. The measurement results should comply with Table 5 and be checked. gear ratio. 7.4 Temperature rise stabilization
7.4.1 Temperature rise stabilization shall be carried out after passing the load test. The lubricating oil is at room temperature, at the rated speed, and loaded to the rated load. Measure the oil temperature every 0.5bh and record it. 】h The oil temperature is stable if the oil temperature change does not exceed 1C. The temperature rise test should be no less than 4 hours, and the temperature and temperature rise stabilization time should be recorded.
7.4.2 When using an expansion thermometer, the method shown in Figure 3 should be used, starting from the vent hole. Medical meter
Steel sleeve

7.4.3 Measurement of ambient temperature
Failure at 1.5m from the surface to be measured Set up the thermometer so that it is at the same height as the product being measured. The thermometer should be placed so that it is not affected by external radiant heat and airflow. The reading is the ambient temperature. 7.4.4 When the temperature rise of the product being measured is stable, measure the difference between the maximum temperature and the ambient temperature. The value is the temperature rise of the product under test. The measurement results should comply with Table 5. 7.5 Pop sound measurement
Under the conditions of Article 7.2, the product noise is measured. The method is in accordance with GB2806, and the A-weighted sound is used. Pressure level measurement, the measurement results should comply with Table 5.
7.6 Overload test
The overload test of the variable speed bearing is immediately after the load test. The lubricating oil is still in a hot state. At the rated speed, it is loaded to 160% of the rated load, and the test takes a lot of time. in 2 minutes. The overload test should not cause damage in the form of gluing, breakage, etc., and it should be able to operate normally after the test. 8 Inspection Rules
8.1 Variable speed bearings must pass the inspection by the quality inspection department of the manufacturer and be accompanied by a certificate before leaving the factory. 8.2 Finished variable speed bearings shall be randomly inspected in accordance with GB2828. The sample size shall be drawn according to S-3. The AQL value of the main item shall be 2.5. The AQL value of the minor item shall be 6.5. Judgment shall be made according to the prescribed rejection and acceptance judgment numbers Re and Ac, 8.3 The sampling inspection items of variable speed bearings are shown in Table 8. Table 8
