Double Pitch roller chains are created in accordance together with the ASME/ANSI B29.3 (Transmission Series) and B29.4 (Conveyor Series) American roller chain specifications. Generally these chains are very similar to ASME/ANSI regular merchandise except the pitch is double. They can be offered in Transmission Series, Conveyor Series with Normal (smaller) Rollers and Conveyor Series with Substantial (oversized) Rollers.
Transmission Series
This series is often made use of on drives with slow to moderate speeds, low chain loads and long center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain amount is obtained by incorporating 2000 to the ASME/ANSI chain number and also the prefi x letter ?¡ãA?¡À. Note that some corporations usually do not use a prefi x letter for this series so ASMEANSI%20Transmission%20Series%20Double%20Pitch%20Roller%20Chainthe chains may perhaps be represented as A2040, A2050 etc. or 2040, 2050 and so forth.
Conveyor Series with Standard (tiny) Rollers
This series is usually employed on light to reasonable load materials managing conveyors with or without the need 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 hyperlink plates (i.e. link plates with the up coming more substantial chain dimension. The chain variety is observed by adding 2000 on the ASME/ANSI chain quantity and the prefi x letter ?¡ãC?¡À. Chains together with the ?¡ãheavy?¡À form side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Large (oversized) Rollers
These chains possess significant rollers to ensure the chain rolls on a conveyor track decreasing friction. Chain numbers are uncovered during the very same way as noted over except that the final digit over the chain amount is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the massive roller.
On the whole sprockets ought to be generated specially for these chains in accordance on the ASME/ANSI B29.3 and B29.4 requirements having said that, for Transmission Series and Conveyor Series with Normal (modest) Rollers, ASME/ANSI B29.1 Common roller chain sprockets may well be used supplied the amount of teeth is thirty or additional.
