After the JS gear reducer gear is worn, no matter which repair method is used, reassembly and debugging are key steps to ensure the quality of repair:
1. Adjust the meshing accuracy: The contact area and tooth side clearance of the gear must be carefully adjusted during assembly (usually the tooth side gap is between 0.15-0.40mm, specifically determined according to the module) to ensure the correct meshing of the gear and extend the service life.
2. Sealing treatment: The processing joint surfaces of the upper and lower boxes should be thoroughly cleaned, apply a layer of oil-resistant sealant evenly, and then tighten the bolts evenly in diagonal order to prevent oil leakage.
3. Add lubricating oil: Inject the specified type of industrial gear oil (such as No. 150 industrial gear oil). The amount of oil is usually suitable for immersing 1/3 of the large arc bevel gear or reaching 1/2 to 2/3 of the oil level window.
4. No-load and load tests:
(1) No-load test run: Let the reducer run without load for about 30 minutes and observe whether the operation is smooth. There should be no impact, vibration and uneven noise. The bearing temperature rise should not be too high (usually the oil temperature should not exceed 80°C).
(2) Load test run: Gradually increase the load to the rated load, check whether the output torque and speed are normal, and check again whether there is leakage at each joint surface and seal.
