  • Explain the repair method of transmission chain

    26-10-2018

    There are three structures for the transmission chain of agricultural machinery. Sleeve roller chains, hook chains and integrated chains. Most of them work under the condition of being exposed outside and being attacked by dust, so it and their mating secondary sprocket wear are relatively serious. The wear of the chain will increase the pitch. If the worn chain pitch increases to the point where the link contacts the top of the sprocket, it will bite, jam or fall off. The chain must be repaired or replaced. Checking the elongation of the chain after it is worn can be performed on a self-made workbench. During the inspection, a special movable caliper must be made, and the measured chain is placed in water ...

  • Introduction of basic parameters of chain drive

    25-10-2018

    The number of sprocket teeth is to improve the smoothness of the chain transmission and reduce the dynamic load. However, the number of small sprocket teeth should not be too much, otherwise, i will be very large, which will cause the chain drive to skip teeth earlier. After the chain works for a period of time, wear causes the pin to become thinner, and the sleeve and rollers to become thinner. Under the action of the tensile load F, the chain pitch is extended. After the chain pitch becomes longer, the pitch circle d moves toward the tooth top when the chain is wound around the sprocket. Generally, the number of chain links is even to avoid the use of transition joints. In order to make the wear uniform and improve the life, the number of sprocket teeth and the number of chain links should be mutually prime, if the mutual prime cannot be guaranteed, the common factor should also be made ...

  • Chain drive types and features

    24-10-2018

    According to different uses, chains can be divided into three categories: lifting chains, traction chains and transmission chains. The lifting chain is mainly used for lifting heavy objects in hoisting machinery, and its working speed is v≤0.25m / s; the traction chain is mainly used for moving heavy objects in chain conveyors, and its working speed is v≤4m / s; the driving chain is used for Movement and power are transmitted in general machinery, usually working speed v≤15m / s. There are two types of transmission chain: toothed chain and roller chain. The toothed chain is driven by the meshing of a specific toothed chain and a sprocket. The toothed chain is stable and has low noise, so it is also called a silent chain transmission. Toothed chain allows working speed up to 40m / s, ...

  • Introduction to some principles of chain drive

    23-10-2018

    Chain transmission is a transmission method that transmits the motion and power of a driving sprocket with a special tooth shape to a driven sprocket with a special tooth shape through a chain. Chain drive has many advantages. Compared with belt drive, it has no elastic sliding and slipping. The average transmission ratio is accurate, the work is reliable, and the efficiency is high. The transmission power is large, the overload capacity is strong, and the transmission size under the same working conditions is small. The tight force is small, and the pressure on the shaft is small; it can work in harsh environments such as high temperature, humidity, dust, and pollution. The disadvantages of chain transmission are: it can only be used for transmission between two parallel shafts ...

  • Working principle and characteristics of chain conveyor line

    22-10-2018

    The chain conveyor line can also be called a chain line. The chain conveying line is a device for conveying materials by using the chain as a traction and carrier. The chain can use ordinary sleeve roller conveyor chains, or other various special chains (such as accumulation chain, double-speed chain). The chain conveyor line mainly transports pallets, large turnover boxes, etc. The chain conveyor line is a widely used line conveyor equipment. The chain conveyor line is a non-standard equipment. Customers can customize it according to their needs. Working principle: The chain conveyor line is on the load chain, and a higher load roller attachment is added between each link to carry ...

  • Common chain characteristics

    21-10-2018

    A chain is a common transmission device. The working principle of a chain is to reduce the friction between the chain and the sprocket through a hyperbolic arc chain, reduce the energy loss during power transmission, and obtain higher transmission efficiency. The application of chain drive is mainly concentrated on some situations with higher power but slower running speed, so that the chain drive can obtain more obvious advantages. Chain transmission uses a wide variety of products and complete products, including toothed chains for transmission, continuously variable transmission chains, long-pitch conveyor chains, short-pitch roller chains, double-pitch roller conveyor chains, double-speed conveyor chains, transmission With sleeve chain, bent plate for heavy load transmission ...

  • What are the specifications of the drive chain

    20-10-2018

    The transmission chain is relatively standard, and specifications such as plate chain, double speed chain, roller chain are too cumbersome. Here are some of your most commonly used ones. Transmission chain is divided into A series and B series. A series conforms to the size specifications of the US chain standard; B series conforms to the European (mainly British) two chains with little difference; A series of chains have a certain proportion of rollers and pins, while B series parts are mainly There is no obvious ratio between the size and the pitch. Except for the B series, which has a 12B specification lower than the A series, the rest of the A series products with the same specifications are actually indifferent, but the landlord must ...

  • How to clean the chain

    19-10-2018

    Precautions Do not directly immerse the chain in strong acidic and strong alkaline cleaners such as diesel, gasoline, kerosene, WD-40, and degreaser, because the inner ring bearing of the chain is injected with high viscosity oil. After washing off, the inner ring will become dry, no matter how much low viscosity chain oil is added afterwards, there is nothing to repair. The recommended cleaning method is hot soapy water and hand sanitizer. You can also use a discarded toothbrush or a slightly harder brush. Wash directly with water. The cleaning effect is not very good, and it needs to be dried after cleaning, otherwise it will rust. Special chain cleaners are generally imported products ...
