The classification and principle of chains

Drive with a Roller Chain, short pitch drive with double pitch roller chain and transmission chain with the sleeve, overloading transmission with curved plate roller chain, use of tooth shape chain, stepless variable speed chain, short pitch roller chain and transmission with double pitch roller chain and transmission chain with the sleeve, overloading transmission with curved plate roller chain, use of tooth shape chain, stepless variable speed chain, long pitch roller conveyor chain conveyor chain, short pitch, double pitch roller Conveying chain, double speed conveying chain, plate chain, etc.
Other products are as follows:
1. Stainless steel chain: parts material is stainless steel, this chain is suitable for food industry and vulnerable to chemical, drug and other corrosive occasions, can also be used in high and low temperature occasions.
2. Nickel plated chain, zinc plated chain, chromium plated chain: all carbon steel materials composed of the chain can be surface treatment, the surface of the parts after nickel plated, zinc plated or chromium plated, can be suitable for outdoor rain erosion and other occasions, but can not prevent strong chemical liquid corrosion.
3. Self-lubricating chain: some parts are made of a sintered metal soaked in lubricating oil. This chain has the characteristics of wear-resistant Chain Plate Conveyor, excellent corrosion resistance, no maintenance (maintenance-free) and long service life. Widely used in high stress, wear resistance requirements, and can not often maintain the occasion, such as food industry automatic production lines, high-grade bicycle racing, less maintenance of high-precision transmission machinery.
4. O-ring chain: the o-ring is installed 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 pre-lubricated strictly. Because the chain has super parts and reliable lubrication, can be used in motorcycle and other open drive.
5. Rubber chain: This kind of chain is based on the A, B series chain chain with u-shaped attached plate, glued rubber (such as natural rubber NR, silicone rubber SI, etc.) on the attached plate can increase wear capacity, reduce noise, increase shock resistance. For conveying.
6. Sharp tooth chain: this kind of chain is widely used in the wood industry, such as wood feeding and output, cutting, transfer table conveying, etc
7. Agricultural machinery chain: agricultural machinery chain is suitable for field operation machinery such as walking tractors, threshing machines, combine harvesters and so on. The chain should be low-cost but impact-resistant and wear-resistant. In addition, the chain should be greased or self-lubricating.
8. High strength chain: is a special roller chain, by improving the shape of the chain plate, thickening the chain plate, fine punching the chain plate hole, heat treatment of the pin shaft strengthening, can improve the tensile strength of 15~30%, and has good impact performance, fatigue performance.
9. Side bent chain: this kind of chain has large hinge clearance and chain plate clearance, so it has great flexibility and can be used for bending transmission and conveying.
10. Escalator chain: used for escalators and pedestrian walkways. Due to the long working time and high safety requirements, the escalator runs smoothly. Therefore, it is required that the cascade chain must reach the specified small ultimate tensile load, the total length deviation and the step distance deviation of the two paired chains.
11. Motorcycle chain: defined by the chain of usage, from the structure of the chain, there are two type of roller chain with sleeve chain, from the part of motorcycle use, it has the use two kinds of engines used within and outside the engine, the engine used within the chain is mostly box chain structure, outside the engine using the chain of transmission chain is used to drive the rear wheels, mostly use the roller chain. Special care should be taken to ensure fatigue performance of such chains.
12. Agricultural clamping conveyor chain: suitable for walking wheat, rice harvester and fixed type motor rice and wheat thresher, as well as semi-feed type combine harvester.
13. Hollow pin chain: used for conveying, single pitch, double pitch, long pitch. Attachments or bars can be inserted into any link of the chain without removing the chain.
14. Timing chain: used for transmission between engine crankshaft and camshaft. Due to the engine piston stroke and exhaust time with strict requirements, it is called the use of chain time chain. Both roller chain and toothed chain can be used as timing chain. Timing chain is mainly used for driving 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, so the requirements of the timing chain in addition to high precision requirements, wear resistance is also quite high.
Chain, as a kind of common power transfer device, through the "chain" of hyperbolic arc design, reduce friction, used in power is larger and the running speed is slow, than belt drive has obvious advantages, such as tank, air compressor, etc., but the transmission speed too fast, because the chain flexibility than the belt transmission.
