Double Pitch roller chains are created in accordance with all the ASME/ANSI B29.3 (Transmission Series) and B29.4 (Conveyor Series) American roller chain specifications. Normally these chains are related to ASME/ANSI common solutions except the pitch is double. They’re offered in Transmission Series, Conveyor Series with Standard (compact) Rollers and Conveyor Series with Significant (oversized) Rollers.
Transmission Series
This series is often employed on drives with slow to reasonable speeds, low chain loads and prolonged center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain amount is obtained by including 2000 to the ASME/ANSI chain number plus the prefi x letter ?¡ãA?¡À. Note that some companies don’t use a prefi x letter for this series so the chains might be represented as A2040, A2050 etc. or 2040, 2050 and so forth.
Conveyor Series with Conventional (compact) Rollers
This series is usually made use of on light to moderate load materials managing conveyors with or with out attachment backlinks. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and more substantial have ?¡ãHeavy?¡À series website link plates (i.e. website link plates with the subsequent greater chain size. The chain number is observed by incorporating 2000 towards the ASME/ANSI chain variety as well as prefi x letter ?¡ãC?¡À. Chains with the ?¡ãheavy?¡À type 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 a conveyor track cutting down friction. Chain numbers are found inside the similar way as noted over except that the final digit around the chain amount is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the substantial roller.
In general sprockets need to be created specially for these chains in accordance to the ASME/ANSI B29.3 and B29.4 requirements on the other hand, for Transmission Series and Conveyor Series with Standard (little) Rollers, ASME/ANSI B29.1 Normal roller chain sprockets may perhaps be applied supplied the amount of teeth is thirty or more.
