Friction is a process that must occur when the brake is running. During the friction of the brake lining and the coupling, the outer raw materials will be lost and transferred due to mutual reaction, which will cause wear and tear. This will gradually increase the gap between the brakes until the lining and drum can no longer be used, which is the working life of the brake.
From the perspective of the reliability of the brake, the friction index of the brake is very high, especially at high temperatures, it can still maintain a large friction index, that is, there is sufficient braking friction torque, but generally, the more the friction index The greater the friction, the higher the resistance generated by the friction, and the greater the shear stress on the outside. Therefore, the loss or damage of the raw material on the friction surface will be more severe, the more abrasion will occur, and the working life will also be greater. The shorter, so friction and wear are two related and contradictory aspects during the friction period. Different working environments and conditions will have different emphasis, but for the brake, some frictional resistance is required but it will not cause a relatively large amount of friction. The wear, brake wear and friction state during friction are related, and they vary with the working environment and the raw materials of the brake.
