The hammer crusher is subjected to large torque or vibration during operation, which often causes failure of the transmission system. Commonly: bearing chamber, bearing position wear, pulley hub, shaft head, keyway wear, etc.
After the above problems occur, the traditional maintenance methods are mainly repaired by repair welding or brush plating. However, both have certain drawbacks: the thermal stress generated by the high temperature of the repair welding cannot be completely eliminated, which may cause damage to the material and cause bending or breakage of the parts. While the brush plating is limited by the thickness of the coating, it is easy to peel off, and the above two methods are all repairing the metal with metal, and the "hard-to-hard" cooperation relationship cannot be changed, and under the combined action of each force, the wear is still caused again.
The above-mentioned maintenance methods are not common in Western countries. Developed countries such as Europe and the United States often use polymer composite materials for the above problems. The most mature application is the 1st line technology product, which has super strong adhesion. Excellent comprehensive performance such as compressive strength, which can be repaired on site without disassembly and machining. The maintenance of polymer materials has no influence on the thermal stress of repair welding, and the thickness of repair is not limited. At the same time, the metal material of the product does not have the concession, which can absorb the shock and vibration of the equipment, avoid the possibility of re-wearing, and greatly extend the equipment components. The longevity of the business saves the company a lot of downtime and creates huge economic value.
