Abstract
The utility model discloses a drum brake disc for a mine hoist, which comprises a drum brake disc main body, and is characterized in that the roughness of the brake friction surface of the drum brake disc Ra is equal to 0.2-0 .5 Mum. The utility model reduces the roughness of the surface of the brake disc, so that the wear and corrosion resistance of the surface of the brake disc are improved, the wear loss of a brake bush is reduced, and the amount of deflection is controlled, thereby prolonging the service life of a brake shoe of a disc brake and the safety of the disc brake.
Description
Technical field
The utility model relates to the brake disc that mine hoist is used.
Background technology
The brake system of mine hoist mainly partly is made up of disc-brake, reel brake disc, Hydraulic Station etc.When mine hoist needs glancing impact, disc-brake is a braking force with the elastic force of butterfly spring, and the brake shoe by disc-brake contacts with the reel brake disc, thereby mine hoist is stopped.
Limit by the machinework condition, the drag friction roughness of surface of reel brake disc is up to Ra=3.2 μ m, because the service life that the roughness height has reduced the disc-brake brake shoe, accelerated the replacement cycle of brake shoe, improved use cost, and make the brake disc beat excessive after the wearing and tearing, influence the deceleration and stopping performance of disc-brake.
Summary of the invention
The purpose of this utility model provides the reel brake disc that the little mine hoist of a kind of roughness is used.
The reel brake disc that a kind of mine hoist is used, it comprises reel brake disc body, it is characterized in that, the drag friction roughness of surface of reel brake disc is Ra=0.2-0.5 μ m.
Good effect of the present utility model is: thus owing to reduced the brake disc roughness of surface surface abrasion resistance of brake disc and corrosion stability are improved.And the abrasion loss of braking bearing shell is reduced, the beat amount is under control, thereby has improved the service life of disc-brake brake shoe and the safety performance of disc-brake.
Description of drawings
Fig. 1 is the front view of reel brake disc;
Fig. 2 reel is the left view of brake disc.
The specific embodiment
As depicted in figs. 1 and 2, the roughness of the utility model reel brake disc is Ra=0.2-0.5 μ m, and this roughness is after general machine tool machine-shaping, carries out secondary processing again on metal surface processing instrument, forms product.
