Machinery Industry Standard of the People's Republic of China
Double plus chains
Subject content and scope of application
JB/T7364-94
This standard specifies the structural type, basic parameters and dimensions, marking, logo, packaging, transportation and storage requirements of double plus chains. This standard is applicable to various types of stationary conveyors. 2 Reference standards
GB1243.1 Short pitch precision roller chains for transmission GB1244 Short pitch precision roller chains and sleeve chains for transmission Sprocket tooth shape and tolerance GB5269 Double pitch precision roller chains and sprockets for transmission and transportation GB 9785 Terms of chains and sprockets
3 Structural type
3.1 Whole chain
The structural type of the chain is shown in Figure 1.
3.2 Rollers and rollers
Inner chain plate
Sleeve outer chain plate
The rolling part in the middle of the chain plate consists of rollers and rollers, and its structural type has two types as shown in Figures 2a and 2b. The roller contacts the tooling plate, and the roller contacts the sprocket tooth corridor and the track. Approved by the Ministry of Machinery Industry of the People's Republic of China on July 26, 1994 and implemented on July 1, 1995
3.3 Locking parts
JB/T7364-94
The type of locking parts is shown in Figure 3, and it is recommended to use a door opening pin. 2) Split pin
Basic parameters and dimensions
b) Elastic locking plate
The double-speed conveyor chains specified in this standard are divided into 2.5-speed conveyor chains and 3-speed conveyor chains. Their dimensional parameter codes are shown in Figures 1 and 3. The specifications and basic parameters of 2.5-speed conveyor chains are shown in Table 1: the specifications and basic parameters of 3-speed conveyor chains are shown in Table 2. Table 1

Note; 2.5 The chain number of the double-speed and triple-speed conveyor chains is the number of the corresponding double-pitch roller chain for conveying, with the letters "BS\ and "10×speed" in front and connected with "
·mark
".
Model representation method:
Standard number
One whole chain section
One chain number
Marking example:
A triple-speed conveyor chain with a pitch of 38.1mm and a whole chain of 84 sections is marked as BS30-C212AX84JB/T7364--94
6 Marking, packaging, transportation, storage
6.1 The outer link plate of the chain and the outer side of the connecting chain plate should have the chain number, manufacturer's trademark or factory 6.2 After the chain is cleaned and treated with rust prevention, it is packaged with moisture-proof and waterproof packaging materials. The specifications of the chains in the same packaging unit must be the same, and a product certificate must be attached. The product will not rust within one year from the date of leaving the factory under normal transportation and storage conditions. 6.3 The outer wall of each packaging unit should be marked with: a.
Product name and chain number;
Manufacturer number;
Quantity;
Net weight and gross weight;
Packaging, storage and transportation graphic marks:
Manufacturer name;
Manufacturer date.
