Abstract

The invention relates to an air-cooled brake wheel, which includes a brake wheel body and heat dissipation blades. The brake wheel body includes a hub, a bearing sleeve and a spoke connecting the hub and the bearing sleeve. The heat dissipation blades are fixed on the inner peripheral surface of the hub. There is an annular cavity in the hub, and a group of circular through holes are uniformly arranged on the inner peripheral surface of the hub. The hollow cavity communicates with the annular cavity in the hub through the circular through hole on the inner peripheral surface of the hub, and the annular cavity in the hub and the hollow cavity in the heat dissipation blade are filled with cooling fluid; the circulation of the cooling fluid dissipates heat to In the hollow cavity in the heat dissipation blade, the heat dissipation blade rotates with the rotation of the hub, generating flowing air between the hub and the bearing sleeve, which can not only take away the heat generated by the friction of the hub, but also dissipate the coolant in the hollow cavity It accelerates the heat dissipation on the surface of the hub and improves the heat dissipation effect.

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...
