Double Pitch roller chains are generated in accordance with the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain specifications. Usually these chains are comparable to ASME/ANSI regular merchandise except the pitch is double. They may be readily available in Transmission Series, Conveyor Series with Conventional (small) Rollers and Conveyor Series with Significant (oversized) Rollers.
Transmission Series
This series is often utilised on drives with slow to reasonable speeds, lower chain loads and extended center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by including 2000 to the ASME/ANSI chain quantity and also the prefi x letter ?¡ãA?¡À. Note that some firms tend not to use a prefi x letter for this series so the chains may well be represented as A2040, A2050 and so on. or 2040, 2050 etc.
Conveyor Series with Regular (little) Rollers
This series is usually utilised on light to reasonable load materials dealing with conveyors with or with no attachment back links. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and bigger have ?¡ãHeavy?¡À series website link plates (i.e. link plates from the following more substantial chain size. The chain amount is found by including 2000 to the ASME/ANSI chain quantity 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 Massive (oversized) Rollers
These chains possess significant rollers in order that the chain rolls on a conveyor track minimizing friction. Chain numbers are uncovered in the similar way as noted over except the final digit over the chain number is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the massive roller.
Sprockets
In general sprockets should be developed specially for these chains in accordance towards the ASME/ANSI B29.3 and B29.4 specifications on the other hand, for Transmission Series and Conveyor Series with Typical (smaller) Rollers, ASME/ANSI B29.one Normal roller chain sprockets may possibly be applied provided the amount of teeth is thirty or extra.
