    27-03-2018

    Not only is the chain often used in industry, but its shadow can be seen everywhere in life. Let ’s follow Xiaobian to understand what a conveyor chain is! The so-called conveyor chain? It is the chain used to transmit power. For example: long-pitch conveyor chain, short-pitch roller conveyor chain, double-speed conveyor chain, double-pitch roller conveyor chain, etc. What is the role of the conveyor chain? 1. In our life, escalators use escalator chains, and escalator chains are one of the conveyor chains. Its operating principle is: the core of the escalator is two chains, which can rotate around two pairs of gears. And at the top of the escalator ...

  • Causes of galvanized iron chain wear

    01-12-2017

    Compared with ordinary chains, galvanized iron chains have the characteristics of wear resistance, corrosion resistance and rust prevention, so it has a wide range of applications. At present, most galvanized iron chains are attached to the surface of the chain by high-viscosity lubricating oil or grease. Although it can play a certain role in lubricating the chain teeth and the surface of the chain, it can hardly penetrate the internal chain pins, bushes and rollers. Therefore, the galvanized iron chain will wear out when its service life is long. Galvanized iron chain wear will not only affect its own aesthetics, but also cause the chain to become loose or kinked, affecting its service life. When the galvanized iron chain runs at high speed, the lubricant will not be effectively moisturized by the centrifugal force after the lubricant is dropped ...

  • What parts of the drive chain

    01-12-2017

    Transmission chains are mainly used in the mechanical engineering industry to increase the transmission speed of mechanical equipment and improve work efficiency. The reason why the transmission chain can realize fast transmission is inseparable from the cooperation of each component. Today we mainly introduce the various components of the transmission chain and see their respective functions. 1. Chain link: the basic structural unit of the chain. Each link contains a pitch in the longitudinal direction of the chain. 2. Basic chain links: Links in the hanging chain that have the same section or the same section. 3. Joint chain link: Closed link chain link that can be easily disassembled at both ends of the transmission chain. 4. Attachment chain link: with original ...
