Problems solved by technology

[0002] As the driving part of the elevator, the traction machine is a device that drives the elevator car and the counterweight device to run up and down. It is mainly composed of motors, brakes, traction wheels and other components. As the safety component of the elevator, the brake is the basic device to ensure the safe operation of the elevator. - Electric friction type normally closed brake, when the elevator is not working, the brake brakes, when the elevator is running, the brake is released, and when the elevator brakes, it relies on the action of mechanical force to make the friction plate rub against the brake wheel to generate braking torque; When the elevator moves, it relies on electromagnetic force to release the brake. The requirements for the elevator brake are: it can generate enough braking torque. Require; As an elevator safety component, the performance and cost of the brake directly determine the quality and competitiveness of the elevator. In the existing technology, most of the brakes are directly braked on the traction sheave, and the long-term action of the brake is related to The friction of the brake wheel heats up, which leads to the demagnetization of the magnetic steel; there are also some disc brakes that are braked on the brake disc, which are difficult to adjust and difficult to process, and the existing brakes are directly produced by the spring force Acting on the brake wheel, this requires higher performance of the spring, and the electromagnetic force generated by the brake coil also needs to be greater to attract the brake

Abstract

The invention relates to the technical field of elevator manufacturing, in particular to a traction machine brake. The traction machine brake comprises a brake disc. A left brake pad and a right brake pad are arranged on the two sides of the left surface and the right surface of the brake disc respectively. The side, backing on to the brake disc, of the left brake pad is fixed to an armature plate. The side, backing on to the brake disc, of the right brake pad is fixed to an iron core plate right opposite to the armature plate. A connecting part is fixed to the side, close to the brake disc, of the armature plate and located above the brake disc, a connecting part is fixed to the side, close to the brake disc, of the iron core plate and located above the brake disc, and the two connecting parts can be crossed in the left-and-right direction. The connecting part of the armature plate and the connecting part of the iron core plate form a combined connecting part after being crossed and are connected in series through a connecting shaft rod arranged in the front-and-back direction, and the part, in front of the armature plate and the iron core plate, of the connecting shaft rod and the part, at back of the armature plate and the iron core plate, of the connecting shaft rod are connected to a brake installation base. The part, above the connecting shaft rod, of the iron core plate is provided with an electrified coil and a brake spring used for abutting against the armature plate. The traction machine brake is high in safety and stability, small in loss and low in noise and cost.
