Double Pitch roller chains are developed in accordance using the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain standards. Normally these chains are related to ASME/ANSI regular merchandise except that the pitch is double. They may be out there in Transmission Series, Conveyor Series with Typical (smaller) Rollers and Conveyor Series with Massive (oversized) Rollers.
Transmission Series
This series is usually made use of on drives with slow to moderate speeds, lower chain loads and long center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain number is obtained by including 2000 for the ASME/ANSI chain variety and also the prefi x letter ?¡ãA?¡À. Note that some businesses usually do not use a prefi x letter for this series so the chains may possibly be represented as A2040, A2050 and so on. or 2040, 2050 etc.
Conveyor Series with Normal (smaller) Rollers
This series is often utilised on light to moderate load material managing conveyors with or without the need of attachment back links. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and larger have ?¡ãHeavy?¡À series website link plates (i.e. hyperlink plates with the subsequent greater chain dimension. The chain variety is uncovered by adding 2000 to your ASME/ANSI chain quantity along with the prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À kind side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Substantial (oversized) Rollers
These chains possess significant rollers to ensure that the chain rolls on the conveyor track cutting down friction. Chain numbers are discovered inside the very same way as noted over except the last digit within the chain quantity is changed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the massive roller.
Usually sprockets really should be developed specially for these chains according on the ASME/ANSI B29.3 and B29.four standards nevertheless, for Transmission Series and Conveyor Series with Common (small) Rollers, ASME/ANSI B29.one Normal roller chain sprockets might be utilised presented the number of teeth is thirty or much more.
