What are the common chains and which occasions are they suitable for?
Stainless steel chain: The parts are made of stainless steel, which is suitable for use in the food industry and areas susceptible to corrosion by chemicals and drugs. It can also be used in high and low temperature occasions.
Nickel-plated chain, zinc-plated chain, chrome-plated chain: All carbon steel materials can be surface-treated. The surface of the parts is nickel-plated, zinc-plated, or chrome-plated. It can be used in places such as outdoor rain erosion, but it cannot prevent thick Chemical liquid corrosion.
Self-lubricating chain: The parts are made of a sintered metal impregnated with lubricating oil. The chain has the characteristics of wear resistance, corrosion resistance, maintenance-free (maintenance-free), and long service life. It is widely used in places with high stress, wear resistance, and frequent maintenance, such as food industry automation production lines, high-end bicycle racing, and low-maintenance high-precision transmission machinery.
O-shaped seal chain: O-rings for sealing are installed between the inner and outer roller plates of the Roller Chain to prevent dust from entering and grease from flowing out of the hinge. The chain is strictly pre-lubricated. Because the chain has super strong parts and reliable lubrication, it can be used in open transmissions such as motorcycles.
Rubber chain: This type of chain is a U-shaped attachment plate on the outer link of the A and B series-based chains. Adhesive rubber (such as natural rubber NR, silicone rubber SI, etc.) can be added to the attachment plate to increase wear resistance and reduce Noise, increase shock resistance. Used for transportation.
Pointed tooth chain: widely used in the wood industry, such as wood feed and output, cutting, conveying table transportation, etc.
Agricultural machinery chain: suitable for field operation machinery such as walking tractors, threshers, combine harvesters, etc. This type of chain requires low cost but can withstand impact and abrasion. In addition, the chain should be greased or can be automatically lubricated.
High-strength chain: It is a special roller chain. By improving the shape of the chain plate, thickening the chain plate, finely punched chain plate holes, and pin heat treatment and strengthening, it can increase the tensile strength by 15-30%, and has good impact performance Fatigue performance.
Side curved chain: This type of chain has large hinge gap and chain plate gap, so it has greater flexibility and can be used for bending transmission and conveying.
Escalator chain: used for escalators and moving walkways. Due to the long working hours of escalators, high safety requirements and smooth operation. Therefore, this step chain is required to reach the specified minimum ultimate tensile load, the total length deviation and the step distance deviation of the two matched chains.
Motorcycle chain: It is defined by the use of the chain. There are two types of roller chain and sleeve chain from the structure of the chain. It is divided from the parts used on motorcycles. There are two types of use inside the engine and outside the engine. Most of the chains used in the engine are sleeve chain structures. The chains used outside the engine are drive chains used to drive the rear wheels. Most of them use roller chains.
Agricultural clamping Conveyor Chain: suitable for walking wheat, rice harvester, fixed-type rice and wheat thresher, and semi-feed combine harvester.
Hollow pin chain: used for conveying, single pitch, double pitch, long pitch are all available. Attachments or crossbars can be inserted into any chain link without disassembling the chain.
Timing chain: used for transmission between engine crankshaft and camshaft. Because the combination of engine piston stroke and exhaust time has strict requirements, the chain for this purpose is called a timing chain. Both roller chains and toothed chains can be used as timing chains. Timing chain is mainly used for engine (diesel or gasoline) transmission 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 do not even have a tensioning device. Therefore, in addition to the high precision requirements for the time chain, the wear resistance is also very high.
Limitations of the chain: As a common driving force device, the chain uses a hyperbolic arc “chain” design to reduce friction. It is used in places where the power is relatively large and the speed is slower than the belt drive. Advantages, such as tanks, pneumatic compressors, etc., but the transmission speed cannot be too fast, because the flexibility of the chain is not as good as the belt transmission.
