Due to the poor operating environment of the reducer, wear, leakage and other failures often occur. The most important ones are:

1. The bearing room of the reducer wears, which includes the wear of the housing bearing box, the bearing hole in the box body, and the gearbox bearing room;

2, reducer gear shaft shaft wear, the main wear parts in the shaft head, keyway, etc.;

3, reducer drive shaft bearing position wear;

4, reducer leakage surface.

For the wear problem, the traditional solution is repair welding or post-plating machining repair, but both have certain drawbacks: the thermal stress generated by the high temperature of the welding cannot be completely eliminated, and it is easy to cause material damage, resulting in bent or broken parts; Brush plating is limited by the thickness of the coating and is easily peeled off. The above two methods are all metal-repairing metals and cannot change the "hard-to-hard" cooperation relationship. Under the combined effects of various forces, it will still cause re-wear. For some large bearing companies, it is impossible to solve them on the spot, and it is necessary to rely on the repair of foreign companies.

For the leakage problem, the traditional method needs to disassemble and open the speed reducer, replace the sealing gasket or apply the sealant, which not only takes time and labor, but also makes it difficult to ensure the sealing effect, and leakage will occur again during the operation. The polymer material can be used for on-site treatment of leakage. The material has superior adhesion, oil resistance and 350% elongation, overcomes the impact of the reducer vibration, and solves the leakage problem of the reducer well for the enterprise.
