Because of the harsh working environment of Gear Reducers, defects such as wear and leakage are often found.
Common faults of Vertical/Horizontal gear reducer:
Gear Reducers usually presents problems such as wear and leakage in long-term operation, and the most important ones are:
- Wear of Gear Reducers bearing room, which includes wear of shell bearing box, inner bore bearing room and gearbox bearing room.
- Gear Reducers Gear shaft diameter wear, the primary wear place is the shaft head and keyway, etc.
- Gear Reducers drive shaft bearing position is worn.
- Gear Reducers contact leakage
A solution after the failure of Vertical/Horizontal Gear Reducers
Aiming at the problem of Gear Reducers wear, the traditional treatment method is to repair welding or brush plating and then use machining to correct it, but both of them have disadvantages: the thermal stress caused by high temperature replacement welding cannot be completely eliminated, and it is easy to form raw material damage, leading to zigzags or cracking of components; And brush plating by coating thickness constraints, simple drop, and the above two methods are metal to correct the metal, can not change the “hard to hard” cooperation in all aspects of the impact of factors, will still form again wear. If some large bearing enterprises need to repair Gear Reducers, it is impossible to deal with it on site with these two methods, so it mostly needs to rely on external modification.
However, the modification with polymer composite materials will not cause the problem of secondary wear. It has super adhesion, excellent compressive strength and other functions. The use of polymer composite materials to correct, can be disassembled, free from machining (no welding thermal stress), the thickness of the correction is not restricted, can absorb the impact of the equipment shock, avoid re-wear, and greatly extend the service life of equipment components, for the enterprise to save a lot of downtime, play a huge economic value.
For the leakage problem, the traditional method needs to open and open the reducer, replace the gasket or change the sealant, not only time-consuming and laborious, and difficult to ensure the sealing effect, in the work will again present the problem of leakage. The polymer composite material could manage the leakage on site, and the Gear Reducers leakage problem was well dealt with by the company with excellent adhesion, oil resistance and tensile degree of 350 percent, overcoming the impact of vibration formation of reducer.
