Double Pitch roller chains are developed in accordance with all the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain specifications. Generally these chains are very similar to ASME/ANSI standard goods except that the pitch is double. They may be readily available in Transmission Series, Conveyor Series with Typical (small) Rollers and Conveyor Series with Large (oversized) Rollers.
Transmission Series
This series is often applied on drives with slow to moderate speeds, very low chain loads and lengthy center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain number is obtained by including 2000 for the ASME/ANSI chain quantity as well as prefi x letter ?¡ãA?¡À. Note that some providers never use a prefi x letter for this series so the chains may perhaps be represented as A2040, A2050 and so forth. or 2040, 2050 and so on.
Conveyor Series with Common (smaller) Rollers
This series is often applied on light to moderate load materials managing conveyors with or without the need of attachment back links. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and more substantial have ?¡ãHeavy?¡À series hyperlink plates (i.e. link plates of the following larger chain dimension. The chain variety is found by adding 2000 to your ASME/ANSI chain variety plus the prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À style side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Huge (oversized) Rollers
These chains possess massive rollers to ensure the chain rolls on the conveyor track cutting down friction. Chain numbers are located from the same way as mentioned over except the last digit on the chain amount is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the huge roller.
Sprockets
Normally sprockets needs to be developed specially for these chains in accordance to the ASME/ANSI B29.3 and B29.4 requirements having said that, for Transmission Series and Conveyor Series with Typical (little) Rollers, ASME/ANSI B29.one Conventional roller chain sprockets could be applied offered the amount of teeth is 30 or much more.
