Double Pitch roller chains are produced in accordance with the ASME/ANSI B29.three (Transmission Series) and B29.4 (Conveyor Series) American roller chain specifications. Generally these chains are equivalent to ASME/ANSI standard items except the pitch is double. These are available in Transmission Series, Conveyor Series with Typical (small) Rollers and Conveyor Series with Substantial (oversized) Rollers.
Transmission Series
This series is often used on drives with slow to moderate speeds, reduced chain loads and extended center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain number is obtained by adding 2000 towards the ASME/ANSI chain amount along with the prefi x letter ?¡ãA?¡À. Note that some businesses don’t use a prefi x letter for this series so the chains may perhaps be represented as A2040, A2050 and so forth. or 2040, 2050 and so on.
Conveyor Series with Normal (little) Rollers
This series is usually applied on light to reasonable load materials managing conveyors with or with no attachment backlinks. 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. website link plates of your following more substantial chain dimension. The chain number is observed by adding 2000 towards the ASME/ANSI chain variety plus the prefi x letter ?¡ãC?¡À. Chains with the ?¡ãheavy?¡À style side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Substantial (oversized) Rollers
These chains possess large rollers so that the chain rolls on the conveyor track cutting down friction. Chain numbers are located while in the same way as noted over except that the last digit on the chain amount is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the large roller.
Usually sprockets need to be developed specially for these chains according to the ASME/ANSI B29.3 and B29.4 requirements nonetheless, for Transmission Series and Conveyor Series with Normal (modest) Rollers, ASME/ANSI B29.one Conventional roller chain sprockets could be employed offered the number of teeth is thirty or much more.
