Transmission part for elevators

Abstract

The invention provides a transmission part for elevators, which has a damping and noise reduction function and belongs to parts of elevators. The transmission part is in the shape of a flat belt and comprises a tension-resistant bearing core rope (23) and a wrapping layer (22), wherein the tension-resistant bearing core rope (23) is made of metal or non-metal materials and the wrapping layer is made of elastic materials. At least one outer surface of the transmission part is provided with continuous grooves (24), and the center axis (21) penetrates through the grooves (24) continuously and form regular or irregular geometric area units (25) on the outer surface of the transmission part. Since the tension force stressed on the tension-resistant bearing core rope is equal, the service life of the transmission part is prolonged. Further, runout of pulleys is reduced due to the continuous grooves arranged on the outer surfaces, noise of a system is reduced, vibration due to intermittent distribution of the grooves is reduced, and riding comfortability is improved.

Description

technical field [0001] The invention relates to an elevator component, in particular to a flat belt-shaped elevator transmission component with the function of shock absorption and noise reduction. Background technique [0002] In the elevator system, it mainly includes the car, counterweight, driving traction machine, elevator transmission parts, etc. The two ends of the elevator transmission part are respectively connected to the car and the counterweight, and are wound on the traction wheel and the guide wheel. Through the traction force generated by the friction between the elevator transmission part and the traction wheel, the lifting movement of the car and the counterweight is realized to achieve the purpose of transportation. . The traditional way is to use the steel wire rope as the transmission part of the car and the counterweight, relying on the static friction between the wire rope and the traction sheave to realize the up and down movement of the car and the c...

Problems solved by technology

[0003] The wire rope is used as the transmission part, relying on the point contact between the wire rope and the traction wheel, the power is transmitted to the car and the counterweight in the form of friction, which may easily cause insufficient traction and slippage

At the same time, the size of the transmitted power is closely related to the meshing mode between the traction sheave and the wire rope. Usually, V-shaped or semicircular traction sheave grooves are used to increase the contact area between the traction sheave and the wire rope, which can increase the The lifting efficiency of the traction system, however, aggravates the wear of the wire rope and the traction sheave, resulting in a shortened life of the wire rope

In addition, another disadvantage of using wire rope as a transmission component is that the operation of the wire rope needs to add lubricating oil. Long-term use of lubricating oil not only affects the transmission of traction efficiency, but also causes pollution to various components in the elevator shaft.
