Maintenance methods for chains of different materials
Different material chain uses are different, according to different material maintenance methods are also different.
Self-lubricating chain: Some parts are made of a sintered metal impregnated with lubricating oil. This kind of chain has excellent wear and corrosion resistance, no maintenance (maintenance-free), and long service life. Widely used in high force, wear-resistant requirements, and can not often maintenance occasions, such as food industry automated production lines, high-grade bicycle racing, less maintenance of high-precision transmission machinery.
O-ring chain: The roller chain is equipped with an O-ring between the inner and outer chain plates to prevent dust from entering and grease from flowing out of the hinge. The chain is rigorously pre-lubricated. Because the chain has strong parts and reliable lubrication, can be used in motorcycle and other open drive.
Stainless steel chain: parts material for stainless steel, this chain is suitable for use in the food industry and vulnerable to chemical, pharmaceutical and other erosion occasions, can also be used in high and low temperature occasions.
Nickel plating chain, galvanized chain, chromium plating chain: all carbon steel material of the chain can be surface treatment, the surface of the parts after nickel plating, galvanized or chromium plating treatment, can be suitable for outdoor rain erosion and other occasions, but can not prevent concentrated chemical liquid corrosion.
Agricultural machinery chain: agricultural machinery chain is suitable for field operation machinery such as walking tractor, thresher, combine harvester, etc. The chain is required to be inexpensive yet impact-resistant and wear-resistant. In addition, the chain should be greased or self-lubricating.
High strength chain: It is a special roller chain. By improving the shape of the chain plate, thickening the chain plate, fine punching the hole of the chain plate and strengthening the pin shaft by heat treatment, the tensile strength can be increased by 15 ~ 30%, and it has good impact performance and fatigue performance.
Side-bent chain: This chain has a large hinge clearance and chain plate clearance, and thus has a greater flexibility, can be used for bending drive and transmission.
Escalator chain: Used for escalators and automatic pedestrian passages. Due to the long working time of the escalator, the safety requirements are high, and the operation is stable. Therefore, it is required that the cascade chain must reach the specified minimum tensile load, the total length deviation of two paired chains, and the cascade distance deviation.
Motorcycle chain: Defined by the purpose 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 engine use and engine use. The chain used in the engine is mostly sleeve chain structure, and the chain used outside the engine is the transmission chain used to drive the rear wheel, most of which use roller chain. Special attention should be paid to ensuring fatigue performance of such chains.
After the chain is cleaned and refueled, slowly reverse the tooth plate. The chain links coming out from the rear should be able to be straightened. If some chain links still maintain a certain angle, it means that they are not smooth and belong to a dead knot, which should be adjusted. The damaged chain link must be replaced in time. It is recommended to strictly distinguish the three types of pin shafts and use the connecting pin shafts for the maintenance chain.
Conveying chain is an essential part of mechanical equipment, which is related to the daily production efficiency and work quality of equipment. In addition, the lubrication of the chain is also very important, but we can not blindly apply all lubricating oil to the chain
Chain conveyor line can also be called chain line. Chain conveying line is a chain as a traction and carrier for conveying materials equipment, the chain can use ordinary sleeve roller conveying chain, can also use a variety of other special chains (such as deposit chain, double speed chain). Chain conveying line mainly conveying pallets, large turnover boxes, etc.
