Double Pitch roller chains are developed in accordance with all the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain requirements. Generally these chains are related to ASME/ANSI conventional items except the pitch is double. They’re out there in Transmission Series, Conveyor Series with Common (compact) Rollers and Conveyor Series with Big (oversized) Rollers.
Transmission Series
This series is often used on drives with slow to moderate speeds, low chain loads and lengthy center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain amount is obtained by including 2000 towards the ASME/ANSI chain amount along with the prefi x letter ?¡ãA?¡À. Note that some companies tend not to 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 (little) Rollers
This series is usually used on light to moderate load material dealing with conveyors with or with out attachment back links. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and greater have ?¡ãHeavy?¡À series website link plates (i.e. link plates from the upcoming greater chain dimension. The chain variety is observed by incorporating 2000 for the ASME/ANSI chain quantity along with the prefi x letter ?¡ãC?¡À. Chains with the ?¡ãheavy?¡À sort side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Huge (oversized) Rollers
These chains possess substantial rollers in order that the chain rolls on the conveyor track minimizing friction. Chain numbers are found inside the exact same way as mentioned over except the last digit about the chain amount is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the large roller.
Normally sprockets really should be made specially for these chains according to your ASME/ANSI B29.3 and B29.4 specifications nonetheless, for Transmission Series and Conveyor Series with Typical (tiny) Rollers, ASME/ANSI B29.one Standard roller chain sprockets may possibly be applied offered the number of teeth is thirty or a lot more.
