Problems solved by technology

However, when the compensation chain tows the car, it carries a large load. When each chain link passes the highest point of the sliding shaft, the chain link changes the direction of motion, and displacement and severe twist occur between the chain links. The wear resistance of the plastic-impregnated layer And poor tear resistance, easy to wear or crack, so that the impregnated layer falls off the surface of the iron chain, and the service life is short

Embodiment Construction

[0031] The embodiments of the elevator balance compensation chain of the present invention will be further described below in conjunction with the accompanying drawings.

[0032] Figure 1 ~ Figure 3 It is the elevator balance compensation chain shown in the present invention, which includes an iron chain 1, a rubber cylinder 2, and a fiber layer 3. The iron chain 1 is placed in the rubber cylinder 2, and the rubber cylinder 2 is wrapped with a fiber layer 3.

[0033] The above-mentioned fiber layer 3 is composed of short fibers and rubber or plastic or rubber-plastic, and the above-mentioned short fibers are uniformly distributed in the matrix of the above-mentioned rubber or plastic or rubber-plastic, and the thickness of the fiber layer 3 is 0.5-3.5 mm.

[0034] The above-mentioned fiber layer 3 is composed of fiber cloth and rubber or plastic or rubber-plastic, and the above-mentioned rubber or plastic or rubber-plastic is uniformly coated on the above-mentioned fiber clot...

Abstract

The present invention discloses a balance compensation chain for elevator and its prdouction method. It comprises iron chain, rubber column and fibre layer. Said iron chain is placed in the rubber column, and said rubber column is wrapped with fibre layer. Said production method includes: removing rust from iron chain; extruding rubber material into mould to cover iron chain to form rubber column; placing the rubber column into mould and extruding the fibre material into mould to cover rubber column surface to form fibre layer; vulcanizing, cooling and setting, trimming and finishing to obtain the invented product with low noise, good wearability and high tearing strength and extensibility at break.

Description

technical field [0001] This invention relates to a chain for transmission, and more particularly to a traction chain for balancing and compensating lift lift. Background technique [0002] The elevator balance compensation chain is used to connect the car and the counterweight of the elevator. It is mainly used to balance the weight of the traction rope and the accompanying cable, and to balance the operation of the elevator. It is required to have a large load, low operating noise, and flexible bending. features. At present, the chains used for elevator lifting balance compensation: one is to use metal light chains. During the operation of the elevator, the chains directly collide with each other, making noise and easy to rust; It can slow down the impact between chain links, but the plastic sheath of this kind of compensation chain is easy to crack and fall off, and the service life is short; the third is to wear hemp rope or steel wire rope between...
