Double Pitch roller chains are developed in accordance with the ASME/ANSI B29.3 (Transmission Series) and B29.4 (Conveyor Series) American roller chain standards. Normally these chains are similar to ASME/ANSI typical goods except that the pitch is double. They are obtainable in Transmission Series, Conveyor Series with Regular (small) Rollers and Conveyor Series with Huge (oversized) Rollers.
Transmission Series
This series is usually utilized on drives with slow to moderate speeds, very low chain loads and extended center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain amount is obtained by incorporating 2000 to the ASME/ANSI chain variety and also the prefi x letter ?¡ãA?¡À. Note that some providers never use a prefi x letter for this series so the chains could be represented as A2040, A2050 etc. or 2040, 2050 etc.
Conveyor Series with Standard (tiny) Rollers
This series is often applied on light to moderate load materials managing conveyors with or devoid of attachment back links. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and bigger have ?¡ãHeavy?¡À series website link plates (i.e. website link plates of your next larger chain dimension. The chain variety is discovered by including 2000 to the ASME/ANSI chain variety plus the prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À sort side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Huge (oversized) Rollers
These chains possess huge rollers in order that the chain rolls on a conveyor track reducing friction. Chain numbers are discovered during the same way as noted above except that the final digit within the chain variety is changed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the significant roller.
On the whole sprockets needs to be created specially for these chains in accordance towards the ASME/ANSI B29.3 and B29.four specifications nevertheless, for Transmission Series and Conveyor Series with Common (little) Rollers, ASME/ANSI B29.1 Common roller chain sprockets may perhaps be made use of offered the number of teeth is 30 or much more.
