Double Pitch roller chains are generated in accordance using the ASME/ANSI B29.three (Transmission Series) and B29.4 (Conveyor Series) American roller chain standards. Generally these chains are equivalent to ASME/ANSI normal items except the pitch is double. They’re obtainable in Transmission Series, Conveyor Series with Normal (modest) Rollers and Conveyor Series with Large (oversized) Rollers.
Transmission Series
This series is usually employed on drives with slow to reasonable speeds, low chain loads and lengthy center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain variety is obtained by including 2000 to the ASME/ANSI chain number and the prefi x letter ?¡ãA?¡À. Note that some companies don’t use a prefi x letter for this series so the chains may perhaps be represented as A2040, A2050 etc. or 2040, 2050 etc.
Conveyor Series with Normal (compact) Rollers
This series is usually utilized on light to moderate load material managing conveyors with or without having attachment links. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and greater have ?¡ãHeavy?¡À series link plates (i.e. link plates in the subsequent larger chain size. The chain amount is discovered by adding 2000 to your ASME/ANSI chain variety as well as the prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À style side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Huge (oversized) Rollers
These chains possess substantial rollers to ensure that the chain rolls on the conveyor track reducing friction. Chain numbers are identified within the same way as noted above except that the final digit within the chain amount is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the substantial roller.
Sprockets
Usually sprockets ought to be created specially for these chains in accordance on the ASME/ANSI B29.three and B29.4 specifications even so, for Transmission Series and Conveyor Series with Conventional (tiny) Rollers, ASME/ANSI B29.one Conventional roller chain sprockets may be made use of offered the amount of teeth is 30 or a lot more.
