Elevator traction machine shock absorber based on multi-layer metal rubber and its working method

Abstract

The invention relates to an elevator tractor damper based on multilayer metal rubber. The elevator tractor damper comprises a base, wherein at least four cushion fixing seats are symmetrically arranged on the upper end surface of the base, a boss is arranged in the center of the cushion fixing seats, hemispherical high-density metal rubber is arranged above the cushion fixing seats, a groove whichis matched with the boss in the center of the cushion fixing seats so as to limit the high-density metal rubber to slide is formed in the center of the hemispherical plane of the high-density metal rubber, hemispherical low-density metal rubber is arranged above the high-density metal rubber, and a hemispherical groove which is matched with the hemispherical curved surface of the high-density metal rubber is formed in the center of the hemispherical plane of the low-density metal rubber. The invention further relates to a working method of the elevator tractor damper based on the multilayer metal rubber. According to the elevator tractor damper, vibration in all directions can be absorbed by the hemispherical high-density metal rubber and the hemispherical low-density metal rubber, and limiting can be performed by a limiting stop block.

Description

technical field [0001] The invention relates to an elevator traction machine shock absorber based on multi-layer metal rubber and a working method thereof. [0002] technical background [0003] With the development of society, people have higher and higher requirements for the comfort of elevator operation. As the main load-bearing carrier and driving device of the elevator car, the elevator traction machine often directly transmits the horizontal and vertical vibrations to the car, which greatly affects the comfort of passengers. For this reason, elevator traction machines are often equipped with corresponding shock absorbers. [0004] At present, the vibration damping devices commonly used in elevator traction machines often use rubber or ordinary elastic materials, and these materials are sensitive to temperature conditions. Whether it is a gearless traction machine without a machine room or a geared traction machine with a machine room, they are located on the top floo...

AI Technical Summary

Problems solved by technology

Whether it is a gearless traction machine without a machine room or a geared traction machine with a machine room, they are located on the top floor of the building, and the top floor is more likely to absorb heat. In this case, the life of the above-mentioned traditional elastic materials will be greatly attenuated, or even lose their original performance.

Moreover, the vibration damping devices of most traction machines are not within the scope of the annual inspection of the elevator, and the problem of whether the elastic materials in the vibration damping devices have reached the end of their service life is often ignored during maintenance.

In addition, when the elevator accelerates or decelerates up and down, the tractor will experience an overturning moment, and it is often difficult for a flexible shock absorber to counteract this overturning moment
