Damping brake device

Abstract

The invention provides a damping brake device. According to the damping brake device, a braking force applying part and a stopping part are combined into a whole, so that the relative position of thebraking force applying part and the stopping part is fixed, the gap value of each part is adjusted in advance, no secondary adjustment is needed during installation, and therefore the installation isconvenient; the braking force applying part and the stopping part are oppositely moved in the axial direction, and automatic centre align is achieved through self-conical structure, so that the stability is good during braking damping; a compression part of the braking force applying part is in spiral axial movement, the movement precision is high, threads of the compression part are self-lockingthreads, so that braking damping force is guaranteed to be applied smoothly, the braking damping force is not automatically reduced, and the device is stable and reliable; a return spring aids the braking force applying part to return to an original position, the brake damping force is relieved, and moving of a mechanism is stable and noiseless; and the device is not influenced by positive and negative rotation directions of rotating parts, the braking damping effect can be achieved in the positive and negative directions, and the braking damping effect is the same.

Description

technical field [0001] The invention relates to a damping and braking device, in particular to a damping and braking device for rotating parts, which is especially suitable for rotating parts with high requirements on braking damping, safety and reliability, and belongs to the field of machinery. Background technique [0002] Damping braking devices have been widely used in many fields of military and civilian use. At present, most of the terminal braking actuators of pneumatic, hydraulic and electromagnetic damping deceleration devices that are widely used are drum or disc damping brake devices, but they have some shortcomings. [0003] For example, the brake friction area of ​​the disc brake device is small, and the brake hydraulic pressure required is high, and the brake device with a hydraulic device can only be used; the brake pad and the brake disc are installed independently, and the relationship between the two needs to be adjusted after installation. The relative p...

Problems solved by technology

[0003] For example, the brake friction area of ​​the disc brake device is small, and the brake hydraulic pressure required is high, and the brake device with a hydraulic device can only be used; the brake pad and the brake disc are installed independently, and the relationship between the two needs to be adjusted after installation. The relative position between them makes the brake clearance and other parameters meet the braking requirements; when the rotating part rotates in both forward and reverse directions, the drum-type single brake pad can only maintain a large braking force in the reverse direction for braking damping, while the opposite direction The braking force is very small, and the braking damping effect is very weak; and in the disc brake, the disc surface is easy to warp and uneven when the brake disc is used, and the braking damping stability is poor when the brake disc brakes

[0004] The braking efficiency and heat dissipation of drum brakes are poor, and a large amount of heat will be accumulated during the braking process. The brake should be regularly adjusted to the clearance of the brake shoe
