1. The outer surface of the reducer should be flat and smooth, and the fasteners must not be loose.
2. The reducer is sealed, and the joints must not leak oil.
3. When turning the input shaft of the reducer by hand, it must be relaxed and stable without jamming.
4. The axial working clearance should meet the regulations.
Planetary reducer test method:
1. After the reducer has passed the test, the load test should be carried out.
2. At the rated speed, the reducer is loaded step by step according to 25%, 50%, 75%, 100%, 110%, and 125% of its rated torque.
3. For reducers that operate in both directions or do not specify the direction of rotation, positive and negative tests should be carried out respectively.
4. In the thermal power load test, the temperature of the reducer oil pool is stable for two hours.The temperature should meet the requirements, and there is no oil leakage at the seals, joints and joints.
Planetary reducer inspection items:
1. Backlash and contact spots.
2. Axial clearance.
3. The stability, noise, temperature rise and sealing of the transmission.
4. Paint and appearance quality.
Acceptance rules for planetary reducers:
1. The quality inspection department of the manufacturer is responsible for the inspection and acceptance of the planetary reducer, and issues a certificate of conformity.
2. Inspection instruments and instrumentation systems must be measured and verified by metrological analysis.
Mass production of reducers with the same specifications allows 10% sampling.The test failure rate should be another 20%, still failing, should all pass the test.
