In the long-term operation of the reducer, there are often faults such as wear and leakage. The most important ones are:
1. The bearing chamber of the reducer is worn, which in turn includes the wear of the bearing housing of the housing, the bearing chamber of the housing, and the bearing chamber of the transmission.
2. The shaft diameter of the gear shaft of the reducer is worn, and the main wear parts are in the shaft head and keyway.
3. The bearing position of the reducer drive shaft is worn.
4. The reducer joint surface leaks.
For the wear problem, the traditional solution of the enterprise is repairing after repair welding or brush plating, but both have certain drawbacks: the thermal stress generated by the repair welding high temperature cannot be completely eliminated, which may cause damage to the material and cause the parts to bend or break; Brush plating is limited by the thickness of the coating, and it is easy to peel off. The above two methods use metal to repair the metal, which can not change the "hard to hard" coordination relationship. Under the combined action of each force, it will still cause re-wear. For some large bearing enterprises, it is impossible to solve on-site, and it is necessary to rely on external repair. In the contemporary Western countries, the repair methods of polymer composite materials are often used for the above problems, and the application of Mikawara technology products with more applications has superior adhesion and excellent compressive strength. The application of polymer material repair can be free of disassembly and machining without the influence of repair welding thermal stress, and the thickness of the repair is not limited. At the same time, the metal material of the product does not have the concession, which can absorb the shock vibration of the equipment and avoid the wear again. It is possible, and greatly extends the service life of equipment components, saving a lot of downtime for the enterprise and creating huge economic value.
It take a compressed gas as the power to form a high-speed jet to shoot glass beads on surface of work-piece that causes changes on surface and shape of the work-piece. Due to the glass beads` impact to surface, it makes the surface a certain of cleanliness and different roughness.
• It improves the mechanical properties of surface so as to enhance the fatigue-resistance of work-piece.
• It provides with parts-surface a controllable rough-surface to increase the adhesion with the paints, to extend the durability of the paints and it is also benefit to the flow and decoration of paints.
The glass bead can be produced based on the standard of countries or areas, such as EN1423/1424, AASHTO M247, BS6088, JIS R3301 and KS L2521 etc.
