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 chainWww.bzxZ.net
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
