Double Pitch roller chains are created in accordance using the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain standards. On the whole these chains are similar to ASME/ANSI typical goods except the pitch is double. They are offered in Transmission Series, Conveyor Series with Typical (modest) Rollers and Conveyor Series with Large (oversized) Rollers.
Transmission Series
This series is usually used on drives with slow to reasonable speeds, low chain loads and long center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by including 2000 to your ASME/ANSI chain number and the prefi x letter ?¡ãA?¡À. Note that some businesses will not use a prefi x letter for this series so the chains may possibly be represented as A2040, A2050 etc. or 2040, 2050 etc.
Conveyor Series with Typical (compact) Rollers
This series is often employed on light to moderate load materials managing conveyors with or devoid of attachment back links. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and greater have ?¡ãHeavy?¡À series website link plates (i.e. website link plates of the following greater chain dimension. The chain variety is observed by incorporating 2000 to the ASME/ANSI chain amount and also the prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À style side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Substantial (oversized) Rollers
These chains possess large rollers to ensure the chain rolls on the conveyor track cutting down friction. Chain numbers are discovered during the similar way as mentioned over except that the last digit about the chain number is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the large roller.
Normally sprockets need to be produced specially for these chains in accordance to your ASME/ANSI B29.three and B29.4 specifications nonetheless, for Transmission Series and Conveyor Series with Standard (little) Rollers, ASME/ANSI B29.1 Normal roller chain sprockets may possibly be made use of presented the amount of teeth is 30 or far more.
