Double Pitch roller chains are made in accordance using the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain requirements. Normally these chains are very similar to ASME/ANSI common products except that the pitch is double. These are offered in Transmission Series, Conveyor Series with Conventional (smaller) Rollers and Conveyor Series with Massive (oversized) Rollers.
Transmission Series
This series is usually used on drives with slow to reasonable speeds, lower chain loads and lengthy center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain variety is obtained by adding 2000 towards the ASME/ANSI chain variety and also the prefi x letter ?¡ãA?¡À. Note that some providers usually do not use a prefi x letter for this series so the chains may well be represented as A2040, A2050 and so forth. or 2040, 2050 and so forth.
Conveyor Series with Common (modest) Rollers
This series is usually applied on light to moderate load materials handling conveyors with or with out attachment links. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and greater have ?¡ãHeavy?¡À series website link plates (i.e. link plates from the subsequent more substantial chain size. The chain number is identified by incorporating 2000 to the ASME/ANSI chain quantity along with the prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À type side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Significant (oversized) Rollers
These chains possess significant rollers to ensure the chain rolls on the conveyor track minimizing friction. Chain numbers are located from the exact same way as mentioned over except the final digit over the chain variety is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the significant roller.
Sprockets
Normally sprockets should be produced specially for these chains in accordance towards the ASME/ANSI B29.3 and B29.four standards nevertheless, for Transmission Series and Conveyor Series with Conventional (compact) Rollers, ASME/ANSI B29.one Normal roller chain sprockets may be employed offered the quantity of teeth is thirty or extra.
