Problems solved by technology

However, due to the moment when the armature is released, the impact force is very large, and a large impact sound will be generated during the impact, so the noise is relatively large.

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the drawings and embodiments, but it is not a basis for limiting the present invention.

[0021] Examples. A braking method for a traction machine. The armature is actuated by the core attracting the armature. When braking is required, the armature presses the brake disc fixed to the installation shaft of the traction machine onto the installation end cover. Since the armature and the mounting end cover cannot rotate relative to each other, they can only move axially, so that the traction machine can be braked, and when the armature is pressed against the brake disc, an elastic shock-absorbing column is set on the back of the armature to avoid instantaneous pressure of the armature. The impact noise generated by the brake disc. The damping column is fixed on the armature or the end cover. The armature is divided into two left and right parts, and the two armatures are independently braked, which re...

Abstract

The invention discloses a braking method of a tractor and a low-noise brake. An armature is operated through a mode that the armature is attracted through an iron core; when braking is required, the armature compresses a brake disc fixed to a mounting shaft of the tractor on a mounting end cover; as the armature can not rotate relative to the mounting end cover and can only axially move, the armature can brake the tractor; and when the armature is pressed to the brake disc, an elastic shock strut is arranged on the back of the armature, so that the impact noise produced when the armature is instantaneously pressed to the brake disc is avoided. By arranging the shock strut on the armature of the electromagnetic brake, when the armature is pressed to the brake disc, the shock strut on the armature collides with the mounting end cover firstly, so that the impact noise produced when the armature is instantaneously pressed to the brake disc is avoided. The elastic shock strut is very easy to compress and damage when being pressed, so that the pressure to the brake disc is reduced to be the smallest, and the braking effect can not be affected.

Description

Technical field [0001] The invention relates to a braking method and a low-noise brake, in particular to a braking method and a low-noise brake for a traction machine. Background technique [0002] At present, with the continuous development of the national economy and the improvement of people's living standards, modern high-rise buildings are spreading across urban and rural areas. In order to ensure the rapid and safe flow of people in high-rise buildings, to meet the fast-paced needs of modern life, and to improve operating efficiency and equipment performance, the design and manufacturing requirements for elevators are becoming higher and higher. The braking performance of the traction machine directly affects the safety and effectiveness of the elevator. At present, most of the electromagnetic brakes used for traction machine braking are operated by the iron core attracting or releasing the armature, and the released armature instantly compresses the brake disc for braking...
