Double Pitch roller chains are generated in accordance using the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain specifications. In general these chains are similar to ASME/ANSI conventional items except the pitch is double. They can be accessible in Transmission Series, Conveyor Series with Regular (compact) Rollers and Conveyor Series with Huge (oversized) Rollers.
Transmission Series
This series is often used on drives with slow to moderate speeds, minimal chain loads and long center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain variety is obtained by including 2000 to the ASME/ANSI chain amount plus the prefi x letter ?¡ãA?¡À. Note that some companies will not use a prefi x letter for this series so the chains may be represented as A2040, A2050 and so forth. or 2040, 2050 and so forth.
Conveyor Series with Normal (small) Rollers
This series is often made use of on light to moderate load material managing conveyors with or without attachment backlinks. 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. website link plates from the following greater chain dimension. The chain number is uncovered by including 2000 on the ASME/ANSI chain number along with the prefi x letter ?¡ãC?¡À. Chains together with the ?¡ãheavy?¡À form side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Massive (oversized) Rollers
These chains possess big rollers to ensure that the chain rolls on a conveyor track decreasing friction. Chain numbers are identified within the same way as noted over except that the final digit around the chain quantity is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the big roller.
Sprockets
On the whole sprockets should be generated specially for these chains in accordance towards the ASME/ANSI B29.3 and B29.four standards nevertheless, for Transmission Series and Conveyor Series with Common (smaller) Rollers, ASME/ANSI B29.1 Normal roller chain sprockets might be made use of supplied the quantity of teeth is thirty or a lot more.
