Abstract

The invention relates to the technical field of brakes, in particular to a normally closed type brake with a flexible decelerating function. The brake comprises a braking part, a braking housing, a braking pull rod, a braking spring, an adjusting push rod, an adjusting spring and a force applying device. The flexible decelerating function of the brake is achieved by combining the braking spring and the adjusting spring. An adjusting force applied by the adjusting push rod can be adjusted at a force applying end of the force applying device in a stretching process, the adjusting force is applied to the braking spring to weaken a braking force generated by the braking spring, and the residual elastic force of the braking spring is a needed braking force. The process can be changed anytime according to actual conditions, that is, the process is a forming process of the flexible braking force. By matching the braking spring, the adjusting spring and the force applying device in use, the braking force can be applied at any proportion (100% to 0% or 0% to 100%) in the braking process, so that a needed decelerating effect is achieved, a flexible braking effect is achieved, and impact to an operating system is reduced.

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...
