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. On the whole these chains are equivalent to ASME/ANSI typical solutions except the pitch is double. They can be obtainable in Transmission Series, Conveyor Series with Normal (compact) Rollers and Conveyor Series with Large (oversized) Rollers.
Transmission Series
This series is often made use of on drives with slow to moderate speeds, very low chain loads and lengthy center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain variety is obtained by incorporating 2000 on the ASME/ANSI chain amount as well as prefi x letter ?¡ãA?¡À. Note that some corporations 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 Regular (tiny) Rollers
This series is usually applied on light to moderate load material dealing with conveyors with or devoid of attachment hyperlinks. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and bigger have ?¡ãHeavy?¡À series website link plates (i.e. link plates in the up coming bigger chain size. The chain variety is uncovered by incorporating 2000 to your ASME/ANSI chain amount along with the prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À kind side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Substantial (oversized) Rollers
These chains possess massive rollers to ensure the chain rolls on the conveyor track cutting down friction. Chain numbers are observed within the similar way as noted above except that the final digit around the chain number is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the large roller.
Sprockets
Generally sprockets need to be generated specially for these chains in accordance for the ASME/ANSI B29.three and B29.4 requirements having said that, for Transmission Series and Conveyor Series with Common (compact) Rollers, ASME/ANSI B29.one Typical roller chain sprockets might be made use of presented the quantity of teeth is 30 or more.
