Abstract

The invention relates to the technical field of brakes, in particular to a normally closed brake with a flexible deceleration function. The brake includes a brake part, a brake housing, a brake pull rod, a brake spring, an adjustment push rod, an adjustment spring and a force applying device. The flexible deceleration function of the brake is realized by the combination of the brake spring and the adjustment spring. The force end of the force application device can adjust the adjustment force applied by the adjustment push rod during the expansion and contraction process. The adjustment force is applied to the brake spring to weaken the brake spring. The braking force and the remaining elastic force of the brake spring are the braking force to be obtained. This process can be changed at any time according to the actual situation, which is the formation process of flexible braking force. Through the combined use of the braking spring, the adjusting spring and the force applying device, the braking force can be applied arbitrarily (100% to 0 or 0 to 100%) during the braking process to achieve the required deceleration effect and realize the flexible braking. Effect, reducing the impact on the operating system.

Description

technical field [0001] The invention relates to the technical field of brakes, in particular to a normally closed brake with a flexible deceleration function. Background technique [0002] All kinds of cranes, belt conveyors, cableways and elevators and other mechanical equipment must be equipped with normally closed brakes. Normally closed brakes are one of the most critical safety protection components in the drive and even the entire operating system. Once the normally closed brake fails, it will seriously threaten the operation safety of mechanical equipment, and even cause vicious safety accidents. [0003] At present, the normally closed brakes on the market are usually caliper, disc or drum brakes. Motors are used to drive hydraulic oil or electromagnets to attract and generate force to offset the brake springs to open the brakes; after the motor or electromagnet is powered off , the counteracting force disappears, and the brake is closed under the action of the brak...
