Double Pitch roller chains are produced in accordance with all the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain standards. Generally these chains are comparable to ASME/ANSI standard items except the pitch is double. These are obtainable in Transmission Series, Conveyor Series with Standard (small) Rollers and Conveyor Series with Massive (oversized) Rollers.
Transmission Series
This series is often used 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 incorporating 2000 towards the ASME/ANSI chain amount plus the prefi x letter ?¡ãA?¡À. Note that some businesses never 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 Common (small) Rollers
This series is often used on light to moderate load material managing conveyors with or with out attachment back links. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and greater have ?¡ãHeavy?¡À series website link plates (i.e. link plates in the following greater chain dimension. The chain number is found by including 2000 on the ASME/ANSI chain quantity plus the prefi x letter ?¡ãC?¡À. Chains together with the ?¡ãheavy?¡À style side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Substantial (oversized) Rollers
These chains possess huge rollers in order that the chain rolls on the conveyor track lowering friction. Chain numbers are located in the same way as noted over except that the last digit within the chain amount is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the huge roller.
Usually sprockets ought to be produced specially for these chains in accordance towards the ASME/ANSI B29.3 and B29.four requirements nonetheless, for Transmission Series and Conveyor Series with Typical (smaller) Rollers, ASME/ANSI B29.1 Common roller chain sprockets may be used offered the quantity of teeth is 30 or far more.
