Double Pitch roller chains are created in accordance with all the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain requirements. Usually these chains are equivalent to ASME/ANSI conventional solutions except the pitch is double. They may be readily available in Transmission Series, Conveyor Series with Common (tiny) Rollers and Conveyor Series with Substantial (oversized) Rollers.
Transmission Series
This series is usually utilised on drives with slow to reasonable speeds, reduced chain loads and lengthy center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain variety is obtained by adding 2000 on the ASME/ANSI chain number plus the prefi x letter ?¡ãA?¡À. Note that some businesses 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 and so on.
Conveyor Series with Normal (smaller) Rollers
This series is usually used on light to reasonable load material handling conveyors with or without attachment hyperlinks. 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. link plates from the following bigger chain dimension. The chain number is uncovered by incorporating 2000 towards the ASME/ANSI chain quantity and also the prefi x letter ?¡ãC?¡À. Chains together with the ?¡ãheavy?¡À form side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Substantial (oversized) Rollers
These chains possess substantial rollers to ensure the chain rolls on the conveyor track lowering friction. Chain numbers are located within the very same way as noted over except the final digit to the chain number is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the big roller.
Sprockets
In general sprockets need to be developed specially for these chains according to your ASME/ANSI B29.three and B29.four standards having said that, for Transmission Series and Conveyor Series with Conventional (modest) Rollers, ASME/ANSI B29.1 Conventional roller chain sprockets might be utilised presented the amount of teeth is thirty or far more.
