Double Pitch roller chains are generated in accordance with the ASME/ANSI B29.three (Transmission Series) and B29.4 (Conveyor Series) American roller chain requirements. Usually these chains are very similar to ASME/ANSI normal items except that the pitch is double. They can be offered in Transmission Series, Conveyor Series with Typical (modest) Rollers and Conveyor Series with Big (oversized) Rollers.
Transmission Series
This series is often employed on drives with slow to moderate speeds, minimal chain loads and prolonged center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain number is obtained by incorporating 2000 to your ASME/ANSI chain variety and also the prefi x letter ?¡ãA?¡À. Note that some organizations usually do not use a prefi x letter for this series so the chains might be represented as A2040, A2050 and so forth. or 2040, 2050 etc.
Conveyor Series with Conventional (modest) Rollers
This series is often utilized on light to reasonable load material handling conveyors with or with no attachment hyperlinks. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and bigger have ?¡ãHeavy?¡À series website link plates (i.e. website link plates in the up coming more substantial chain size. The chain variety is identified by incorporating 2000 to the ASME/ANSI chain amount and also the prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À kind side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Massive (oversized) Rollers
These chains possess big rollers in order that the chain rolls on a conveyor track minimizing friction. Chain numbers are observed from the similar way as noted over except the final digit over the chain quantity is changed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the substantial roller.
Usually sprockets needs to be made specially for these chains in accordance to the ASME/ANSI B29.three and B29.4 requirements nonetheless, for Transmission Series and Conveyor Series with Normal (tiny) Rollers, ASME/ANSI B29.1 Regular roller chain sprockets could be applied supplied the number of teeth is thirty or a lot more.
