The open-bearing rubber mixing machine is mainly composed of rollers, frames, glands, pitch adjustment devices, safety devices, motors and transmission devices, braking devices, lubrication systems, cooling systems, and electrical control systems.
The open bearing rubber mixer is subjected to vibration, impact and other compound forces during production and operation, and faults such as bearing chamber wear often occur. Traditional methods include surfacing, thermal spraying, and electric brushing, but they all have certain drawbacks.
The thermal stress caused by the high temperature of repair welding can not be completely eliminated, and it is easy to cause material damage and cause the parts to bend or break;
However, electric brush plating is limited by the thickness of the coating, which is easy to peel off, and the above two methods use metal to repair the metal, which cannot change the “hard-to-hard” coordination relationship. Under the combined action of various forces, it will still cause re-wear.
Western countries mostly use polymer composite repair methods for the above problems, and the most widely used is the Fuschlan technology system, which has super adhesion, excellent compressive strength and other comprehensive properties, and can be disassembled and machine-free. There is no effect of repair welding thermal stress, and the repair thickness is not limited. At the same time, the product has a retreat that the metal material does not have, which can absorb the shock and vibration of the equipment and avoid the possibility of re-wearing.
