Different Types of Chains and Application
Chain as a common transmission force device: through the "chain" design of double arcs, the magic friction force is reduced, and it is used in places where the speed of the larger surface of the power is relatively slow. The belt transmission has obvious advantages, such as Tanks, pneumatic compressors, etc., but the transmission speed can not be too fast, because the flexibility of the chain is not as good as the belt transmission.
The material of the parts is stainless steel. This kind of chain is suitable for use in the food industry and in the occasions where it is easily eroded by chemicals and medicines. It can also be used in high and low temperature occasions.
All carbon steel chains can be surface-treated, and the surface of the parts is treated with nickel-plated, zinc-plated or chrome-plated, which can be used in outdoor rainwater erosion and other occasions, but cannot prevent concentrated chemical liquid corrosion.
For conveying, single pitch, double pitch and long pitch are available. Attachments or crossbars can be inserted into any link of the chain without removing the chain.
◆Self-lubricating chain:
Some parts are made of a sintered metal impregnated with lubricating oil. This kind of chain has the characteristics of excellent wear resistance and corrosion resistance, no maintenance (maintenance-free) and long service life. It is widely used in Occasions with high stress, wear resistance requirements, and frequent maintenance, such as: industrial automation production lines, high-end bicycle racing, less maintenance of high-precision transmission machinery.
◆O type sealing ring chain:
There are O type sealing rings for sealing between the inner and outer chain plates of the roller chain to prevent dust from entering and grease from flowing out of the hinge. The chain is heavily pre-lubricated. Because the chain has super strong parts and reliable lubrication, it can be used in open transmission such as motorcycles.
◆Rubber chain:
This type of chain is based on A and B series chains with a U-shaped attachment plate added to the outer link, and rubber (such as natural rubber NR, silicone rubber SI, etc.) is attached to the attachment plate to increase the wear capacity. Reduce noise and increase shock resistance. for conveying.
◆Tine chain:
This chain is widely used in the wood industry, such as wood feeding and output, cutting, conveyor table conveying, etc.
◆Agricultural machinery chain:
Agricultural machinery chain is suitable for field operation machinery such as walking tractor, thresher, combine harvester and so on. This kind of chain requires low cost but can withstand shock and wear. In addition, the chain should be greased or self-lubricating.
It is a kind of special roller chain. By improving the shape of the chain plate, thickening the chain plate, fine-blanking the chain plate hole, and strengthening the pin shaft heat treatment, the tensile strength can be increased by 15~30%, and it has good impact performance. , fatigue performance.
◆Side bending chain:
This kind of chain has larger hinge clearance and chain plate clearance, so it has greater flexibility and can be used for bending transmission and conveying.
◆Escalator chain:
Used for escalators and automatic pedestrian passages. Due to the long working time of the escalator and the high safety requirements, it is required that the step chain must reach the specified minimum ultimate tensile load, the total length deviation of the two paired chains, and the step distance deviation.
◆Motorcycle chain:
Defined by the use of the chain, from the structure of the chain, there are two types of roller chain and sleeve chain, from the part used on the motorcycle, it has two types of use inside the engine and outside the engine , Most of the chain used in the engine is a sleeve chain structure, and the chain used outside the engine is a transmission chain used to drive the rear wheel, most of which use a roller chain. Special care should be taken to ensure fatigue properties of such chains.
◆Agricultural clamping conveyor chain:
Suitable for walking wheat and rice harvesters, stationary motorized rice and wheat threshers, and semi-feeding combine harvesters.
◆Timing chain:
Used for transmission between engine crankshaft and camshaft. Since there are strict requirements for the coordination between the engine piston stroke and the exhaust time, the chain used for this purpose is called a timing chain. Both roller chains and toothed chains can be used as timing chains. Timing chains are mainly used for the transmission of engines (diesel or gasoline engines) of automobiles, motorcycles and ships. In order to reduce the weight of the engine, the installation gap between the chain and the engine is very small, and some even have no tensioning device. Therefore, in addition to the high precision requirements for the timing chain, the requirements for wear resistance are also quite high.
