Double Pitch roller chains are produced in accordance using the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain standards. Normally these chains are very similar to ASME/ANSI regular products except the pitch is double. They can be readily available in Transmission Series, Conveyor Series with Typical (smaller) Rollers and Conveyor Series with Substantial (oversized) Rollers.
Transmission Series
This series is usually employed on drives with slow to reasonable speeds, low chain loads and lengthy center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain amount is obtained by incorporating 2000 on the ASME/ANSI chain amount and the prefi x letter ?¡ãA?¡À. Note that some organizations don’t use a prefi x letter for this series so the chains may perhaps be represented as A2040, A2050 and so on. or 2040, 2050 and so on.
Conveyor Series with Standard (modest) Rollers
This series is usually made use of on light to moderate load materials managing conveyors with or with no attachment hyperlinks. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and larger have ?¡ãHeavy?¡À series link plates (i.e. website link plates in the following bigger chain dimension. The chain number is located by incorporating 2000 on the ASME/ANSI chain variety as well as prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À form 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 a conveyor track lowering friction. Chain numbers are uncovered within the same way as noted over except the last digit around the chain variety is changed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the big roller.
Sprockets
Normally sprockets ought to be generated specially for these chains according to the ASME/ANSI B29.3 and B29.4 requirements on the other hand, for Transmission Series and Conveyor Series with Typical (tiny) Rollers, ASME/ANSI B29.one Common roller chain sprockets may perhaps be used provided the quantity of teeth is 30 or additional.
