Air-cooled brake wheel

Abstract

The invention relates to an air-cooled brake wheel. The air-cooled brake wheel comprises a brake wheel body and a heat dissipating blade. The brake wheel body comprises a hub, a bearing bush and a spoke connecting the hub and the bearing bush. The heat dissipating blade is fixed on the inner circumference face of the hub. The hub is internally provided with an annular cavity, and a set of circular through holes are evenly formed in the inner circumference face of the hub, and communicated with the annular cavity in the hub. The heat dissipating blade is internally provided with a hollow cavity which is communicated with the annular cavity in the hub through the circular through holes in the inner circumference face of the hub, and the annular cavity in the hub and the hollow cavity in the heat dissipating blade are filled with cooling liquid. Heat is dissipated to the hollow cavity in the heat dissipating blade through flowing of the cooling liquid, the heat dissipating blade rotates along with the rotation of the hub, flow air is produced between the hub and the bearing bush and can bring the heat produced by the friction of the hub away and dissipate the heat of the cooling liquid in the hollow cavity, the heat dissipation of the surface of the hub is accelerated, and the heat dissipating effect is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical brake equipment, and relates to a brake wheel, in particular to an air-cooled brake wheel. Background technique [0002] All mechanical equipment such as cranes and hoists need to be equipped with braking devices. The brake wheels are held tightly by the brake shoes of the brakes, and the brakes are implemented by the strong friction between the brake shoes and the brake wheels. [0003] During the braking process, since the brake wheel is installed at the high-speed running end of the mechanical equipment, the speed is often above 1000r / min, so high-speed friction will inevitably lead to a sharp rise in the surface temperature of the brake wheel. Under normal conditions, the surface temperature of the brake wheel can reach 600°C, or even higher. Such a high temperature will not only reduce the surface hardness and deformation of the brake wheel, but also cause the abnormal wear of the brake wh...
