ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are created in accordance using the ASME/ANSI B29.three (Transmission Series) and B29.4 (Conveyor Series) American roller chain requirements. On the whole these chains are related to ASME/ANSI conventional goods except that the pitch is double. They can be readily available in Transmission Series, Conveyor Series with Conventional (little) Rollers and Conveyor Series with Significant (oversized) Rollers.
Transmission Series
This series is usually applied on drives with slow to moderate speeds, minimal chain loads and prolonged center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain variety is obtained by including 2000 towards the ASME/ANSI chain quantity as well as the prefi x letter ?¡ãA?¡À. Note that some organizations don’t use a prefi x letter for this series so the chains may be represented as A2040, A2050 etc. or 2040, 2050 and so forth.
Conveyor Series with Regular (small) Rollers
This series is often employed on light to moderate load material managing conveyors with or with out 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 link plates (i.e. website link plates on the subsequent greater chain dimension. The chain quantity is identified by adding 2000 to your ASME/ANSI chain quantity as well as prefi x letter ?¡ãC?¡À. Chains with the ?¡ãheavy?¡À sort side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Large (oversized) Rollers
These chains possess huge rollers so that the chain rolls on a conveyor track minimizing friction. Chain numbers are identified inside the exact same way as mentioned over except that the last digit over the chain number is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the big roller.
Sprockets
Generally sprockets must be generated specially for these chains in accordance to the ASME/ANSI B29.3 and B29.4 specifications however, for Transmission Series and Conveyor Series with Normal (compact) Rollers, ASME/ANSI B29.1 Standard roller chain sprockets may perhaps be utilised offered the quantity of teeth is thirty or additional.
