Machinery Industry Standard of the People's Republic of China Classified method to chain products Classified method to chain products1 Subject content and scope of application This standard specifies the classification method, definition and scope of application of chain products. 2 Reference standard GB9785 chain and sprocket terminology 3 terminology Chain terminology shall be implemented in accordance with the provisions of GB9785. 4 Chain product classification method 4.1 Category Chains are divided into four types according to different uses and functions: transmission chains, conveyor chains, electric chains and special special chains. 4.1.1 Transmission chain is a chain mainly used to transmit power. 4.1.2 Conveyor chain A chain mainly used to transport materials. 4.1.3 Electric lead chain A chain mainly used for pulling out and lifting. 4.1.4 Special-purpose chains are mainly used for chains with special functions and structures on special mechanical devices. 4.2 Structure series JB/T 6368-92 Among similar products, according to the basic structure of the chain, that is, according to the shape of the components, the parts and parts meshing with the chain, the size ratio between parts, etc. Divide the chain product series it belongs to. 4.3 Variety Chain products in the same series are divided into varieties according to the materials used in chain components, chain attachment forms and hinge structures. 4.4 Specifications Chains of the same type are divided into specifications based on pitch, number of rows, chain width and ultimate tensile load. The Ministry of Mechanical and Electronics Industry of the People's Republic of China approved the implementation on 1993-0-01 on 1992-07-15 A1 commonly used series examples Transmission chain Conveyor chain Lead chain one 72 JB/T 6368-92 Appendix A Examples of chain product classificationbzxz.net (supplementary parts)|| tt||Short pitch precision roller chain for A series transmission -Short pitch precision roller chain for B series transmission Weighted series short pitch precision roller chain for transmission-Oil drilling rig transmission roller chain| |tt||-Short-pitch precision sleeve chain for transmission Double-pitch precision roller chain for one transmission Bent roller chain for heavy-duty transmission For transmission Toothed chain -Motorcycle chain Bicycle chain One short pitch precision roller conveyor chain One pair of pitch roller conveyor chain Long-pitch conveyor chain —Flat-top chain for conveying Short-pitch precision sleeve chain for conveying Lightweight double-articulated suspension conveyor chain Easy to disassemble chain| |tt||A buried scraper conveyor chain A steel roller conveyor chain for engineering Steel sleeve conveyor chain for engineering Agricultural roller conveyor chain||tt ||Clamping conveyor chain for agricultural machinery Plate chain Round link chain for lifting High-strength round link chain for mining One hoist round link chain|| tt||Pin chain Cold dial machine chain One-piece heavy-duty electric chain Roller guide chain One electric reference bending plate chain||tt ||Special chain Examples of A2 chain varieties JB/T 6368-- 92 Sliding vane type continuously variable speed chain Protected drag chain Saw chain Boiler chain Tap water slag scraper chain Iron printing oven chain Pipe clamp chain Agricultural reeling chain Thrust Chain Common material!)
