Description

Noise reduction unit for braking and brake

Technical Field

The utility model relates to the technical field of brakes, in particular to a noise reduction unit for braking and a brake.

Background

The shaft sleeve in the brake is matched with the shaft, the shaft sleeve in the brake is matched with the friction disc, the friction disc is driven to rotate when the shaft rotates, and the braking effect of the shaft is achieved by braking and reducing the speed of the friction disc.

In general, no noise reduction measures are adopted in the matching structure between the shaft sleeve and the friction disc, so that the rotation speed of the shaft sleeve and the friction disc is inconsistent due to the hysteresis characteristic of the friction disc when the brake is in use, namely, the shaft sleeve or the shaft drives the friction disc to rotate, and noise is inevitably generated. The traditional noise measure has the advantages that the shaft sleeve is provided with the groove, and the O-shaped ring is sleeved in the groove, so that the noise can be reduced, and the following adverse effects are brought;

(1) When the O-shaped ring and the shaft sleeve are installed, the inner peripheral surface of the friction disc can shear the O-shaped ring, and when severe, the outer surface of the O-shaped ring can be damaged, so that the friction force between the shaft sleeve and the friction disc is increased, and the installation difficulty is increased.

(2) In order to enhance the noise-preventing effect, the size of the O-ring cannot be too small, which means that the width of the groove of the O-ring on the sleeve cannot be too small to achieve sufficient contact between the O-ring and the friction disc, which means that the actual contact area between the sleeve and the friction disc is reduced.
