Problems solved by technology

[0008] Although the brake structure disclosed in this utility model can be reduced in size in the axial direction, there is still the problem that the brake disc is directly in contact with the motor housing, and the air gap of the brake (the distance between the brake disc and the adjacent components) It is also difficult to adjust

Embodiment Construction

[0037] The electromagnetic disk brake of the present invention and the traction machine equipped with the electromagnetic disk brake will be described in detail below in conjunction with the accompanying drawings.

[0038] Such as figure 1 Shown, a kind of electromagnetic disk type brake comprises static iron core 5 and moving iron core 4 interacting by electromagnetic force, brake disc 11 fixed with main shaft 13 (between the rotating shaft 12 of brake disc 11 and the main shaft 13 of motor fixedly connected by splines) and the brake plate 3 that cooperates with the moving iron core 4 to clamp the brake disc 11.

[0039] There are two moving iron cores 4 located on both sides of the static iron core 5 respectively, and two sets of brake discs 11 and brake plates 3 are arranged outside the corresponding moving iron cores 4 in sequence.

[0040] There are two coil windings 10, and there are slots for accommodating the two coil windings 10 respectively. The two slots are symmet...

Abstract

An electromagnetic disc brake and a traction machine equipped with the electromagnetic disc brake. The invention discloses an electromagnetic disc brake, which comprises a static iron core and a moving iron core interacting through electromagnetic force, a brake disc fixed to the main shaft, and a brake disc that cooperates with the moving iron core to clamp the brake disc. There are two moving iron cores, which are respectively located on both sides of the static iron core, and a brake spring is arranged between the two moving iron cores and the static iron core; The coil winding of the moving iron core; the brake disc and the brake plate are two sets, which are sequentially arranged outside the corresponding moving iron core. The static iron core, the two moving iron cores and the two brake plates are fastened through the connecting sleeve. It is connected with the static iron core through interference fit, and the connecting sleeve and the brake plate are riveted together. The invention has the advantages of small volume, safe and reliable use, and convenient maintenance.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to an electromagnet brake and a traction machine equipped with the electromagnet brake. Background technique [0002] The elevator traction machine is the power equipment of the elevator, which is used to convey and transmit power to make the elevator run. It is usually composed of a motor, a brake, a coupling, a reduction box, and a traction wheel. [0003] The traction wire rope goes around the traction sheave, one end of which is connected to the car, and the other end is connected to the counterweight. The motor drives the traction sheave to rotate, relying on the friction between the traction wire rope and the traction sheave to drive the car and the counterweight to move up and down. For the elevator traction machine, the brake is an important safety component, and the electromagnetic disc brake is a relatively common brake form in the prior art. [0004] At present, there are...
