Double Pitch roller chains are created in accordance with all the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain standards. Generally these chains are similar to ASME/ANSI normal products except the pitch is double. They’re obtainable in Transmission Series, Conveyor Series with Common (modest) Rollers and Conveyor Series with Substantial (oversized) Rollers.
Transmission Series
This series is often employed on drives with slow to moderate speeds, minimal chain loads and extended center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain number is obtained by including 2000 on the ASME/ANSI chain quantity as well as the prefi x letter ?¡ãA?¡À. Note that some corporations never use a prefi x letter for this series so the chains may well be represented as A2040, A2050 and so on. or 2040, 2050 etc.
Conveyor Series with Regular (little) Rollers
This series is often used on light to moderate load material dealing with conveyors with or without attachment links. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and larger have ?¡ãHeavy?¡À series link plates (i.e. link plates on the next more substantial chain dimension. The chain quantity is found by including 2000 towards the ASME/ANSI chain number as well as the prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À kind side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Big (oversized) Rollers
These chains possess large rollers so that the chain rolls on the conveyor track minimizing friction. Chain numbers are found while in the similar way as mentioned over except that the final digit within the chain quantity is changed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the massive roller.
Sprockets
Normally sprockets need to be made specially for these chains in accordance to your ASME/ANSI B29.three and B29.4 requirements nonetheless, for Transmission Series and Conveyor Series with Typical (compact) Rollers, ASME/ANSI B29.1 Normal roller chain sprockets may be applied presented the amount of teeth is thirty or more.
