Description

Disc brake with good wear resistance Technical Field The utility model belongs to the technical field of disc brakes, and particularly relates to a disc brake with good wear resistance. Background The disc brake of the belt conveyor is a common braking device which is mainly used for emergency braking, parking braking or dynamic braking, and ensures that the conveyor is safely stopped in the case of power failure, overspeed or emergency. The belt conveyor has the advantages of compact structure, large braking torque and good heat dissipation performance, and is suitable for medium-high speed and high-power belt conveyor systems. During the use process of the disc brake, the hydraulic/pneumatic system keeps pressure during normal operation, the brake caliper is released, the brake disc rotates freely, the system is decompressed (or pressurized according to design) during braking, the brake caliper clamps the brake disc, braking is realized through friction, and the emergency braking is automatically brought into a braking state, such as power failure or safety loop triggering. In the use process of the existing disc brake, fine gravel or other hard particles are easy to adhere to the surface of a brake disc. When the brake caliper clamps the brake disc with the grits, the hard particles can generate intense friction with the surface of the brake disc under the action of huge positive pressure, and under the action of strong clamping force of the brake caliper, the grits are like sharp cutters, and the grits are continuously rubbed and scored on the surface of the brake disc along with the relative movement of the brake caliper and the brake disc, so that scratches with different depths are easily left. Once these scratches appear on the surface of the brake disc, the integrity of the wear layer is severely compromised. The scratches not only thin the thickness of the wear-resistant layer, but also change the physical properties of the surface thereof, reducing the resistance to abrasion. This wear is exacerbated as the service time increases and the number of braking events increases, resulting in a significant decrease in the wear resistance of the brake disc. Disclosure of utility model The utility model aims to provide a disc brake with good wear resistance, and aims to solve the problems that when a brake caliper clamps a brake disc with gravel in the prior art, hard particles can generate severe friction with the surface of the brake disc under the action of huge positive pressure, so that scratches with different depths can be left on the surface of the brake disc, and the scratches can seriously damage the integrity of a wear-resistant layer and reduce the wear resistance of the wear-resistant layer.
