Embodiment Construction

[0021] The present invention will be further explained below in conjunction with the accompanying drawings.

[0022] like figure 1 As shown, a water-cooled plus water-cooled double-acting disc brake device of the present invention includes a brake disc 1 and a brake shoe 6 arranged at the edge of one side of the brake disc 1 .

[0023] like figure 1 , 2 , 3 and 4, the brake disc 1 includes a hub 2, a brake disc base 3, an asbestos-free friction plate 4 and screws 5. The brake disc substrate 3 includes an inner annular disc part 3-1 and an outer annular disc part 3-2, the thickness of the inner annular disc part 3-1 is greater than the thickness of the outer annular disc part 3-2, and the hub 2 is connected to the inner annular disc part 3-2. The disk portion 3-1 is fixedly connected. There are several fan-shaped grooves 3-3 evenly distributed along the annular disc surface on both sides of the outer annular disc part 3-2, and the asbestos-free friction plate 4 is fan-shape...

Abstract

The invention discloses an air-cooling and water-cooling double-acting disc type braking device which comprises a brake disc and a brake block, wherein the brake disc comprises a brake disc substrate; the brake disc substrate comprises an inner side annular disc part and an outer side annular disc part; a hub is fixedly connected with the inner side annular disc part; a plurality of fan-shaped grooves are distributed in each of the two sides of the outer side annular disc part; fan-shaped bulges are arranged on one side of a asbestos-free friction plate and mounted in the fan-shaped grooves; a plurality of axial through holes are uniformly distributed in the inner side annular disc part; radial through holes are formed in each of the inner side annular disc part and the outer side annular disc part; one end of each of the radial through holes is communicated with the corresponding axial through hole; the other ends of the radial through holes directly penetrate through the outer circular surface of the outer side annular disc part; a plurality of cooling water channels are formed in the brake block. According to the air-cooling and water-cooling double-acting disc type braking device, during the braking process, heat absorbed by the brake block is taken away by cooling water, heat absorbed by the brake disc is taken away through heat dissipation channels formed by axial ducts and radial ducts, so that the brake disc can maintain a lower temperature.

Description

technical field [0001] The invention relates to a water-cooled plus water-cooled double-acting disc brake device, which is used to realize long-term braking of a high-speed heavy-duty hoist or a large-capacity down-carrying belt conveyor, and at the same time can ensure that the braking friction surface will not be damaged due to Excessive temperature rise causes brake failure. Background technique [0002] Because the disc brake device has the characteristics of simple structure and large braking torque, the hoist and the lower belt conveyor generally use the disc brake device to realize parking and parking braking to ensure the safe operation of the equipment. In the existing disc brake device, the brake disc is made of steel plate, and the material is 16Mn or a material with similar properties, while the brake shoe is made of non-asbestos friction material. Due to the characteristics of the friction material, about 70% of the heat generated by the friction between the br...
