What are the technical requirements and test methods for gearmotors?

First, the basic requirements of the gear motor should meet:
1, the outer surface should be smooth, smooth;
2, the combination of industrial gear box, seal may not appear oil leakage phenomenon;
3, the firmware, the link must not loose phenomenon;
4, slowdown motor hand rotation, it must be easy and smooth, no jamming phenomenon;
5, in the rated speed and rated load, the motor noise reduction ≤ 80DB (a), temperature ≤ 65 degrees, the maximum oil temperature ≤ 95 degrees;
6, gear motor transmission efficiency and carrying capacity should be consistent with gb / t 16444 requirements;
7, gear reducer motor clearance should be consistent with the provisions.
experiment method:
1, the gear motor after the test should be carried out after the load test;
2, the load test, every ten minutes to record an oil temperature, time, torque and speed;
3, the gear reductions in the rated speed, according to its rated torque of 25%, 50%, 75%, 100%, 110%, 125% step by step loading test;
4, in the thermal power load test deceleration motor oil tank temperature stability for two hours unchanged, the temperature should meet the requirements of the seal, the junction is not allowed to leak phenomenon;
5, for the two-way work or not indicate the direction of rotation of the motor should be positive and negative test, for the one-way work of the motor can be a single test, the direction of rotation must work with the same direction.
Acceptance rules:
1, inspection equipment, instruments must be measured by the measurement test;
2, the motor by the manufacturer of quality inspection departments responsible for inspection and acceptance, and issued a certificate;
3, batch production of the same specifications of the advantages of variable speed drives, allowing 10% of the test (not enough ten should be a test), test failed when the test should be 20%, still unqualified, should all be tested.
