Double Pitch roller chains are produced in accordance with all the ASME/ANSI B29.3 (Transmission Series) and B29.4 (Conveyor Series) American roller chain requirements. Usually these chains are similar to ASME/ANSI common goods except the pitch is double. They are really out there in Transmission Series, Conveyor Series with Normal (tiny) Rollers and Conveyor Series with Large (oversized) Rollers.
Transmission Series
This series is usually utilised on drives with slow to reasonable speeds, minimal chain loads and long center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by adding 2000 for the ASME/ANSI chain variety and the prefi x letter ?¡ãA?¡À. Note that some companies will not use a prefi x letter for this series so the chains may perhaps be represented as A2040, A2050 and so forth. or 2040, 2050 etc.
Conveyor Series with Normal (tiny) Rollers
This series is often applied on light to moderate load materials dealing with conveyors with or with out attachment hyperlinks. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and larger have ?¡ãHeavy?¡À series link plates (i.e. hyperlink plates in the next bigger chain dimension. The chain variety is identified by including 2000 to your ASME/ANSI chain quantity plus the prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À form side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Large (oversized) Rollers
These chains possess massive rollers so that the chain rolls on a conveyor track decreasing friction. Chain numbers are located within the very same way as noted over except the final digit over the chain number is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the massive roller.
Sprockets
On the whole sprockets need to be created specially for these chains according on the ASME/ANSI B29.three and B29.4 requirements having said that, for Transmission Series and Conveyor Series with Standard (compact) Rollers, ASME/ANSI B29.1 Normal roller chain sprockets could be employed supplied the number of teeth is 30 or a lot more.
