Double Pitch roller chains are generated in accordance together with the ASME/ANSI B29.3 (Transmission Series) and B29.4 (Conveyor Series) American roller chain requirements. Generally these chains are equivalent to ASME/ANSI common items except the pitch is double. They are available in Transmission Series, Conveyor Series with Normal (modest) Rollers and Conveyor Series with Substantial (oversized) Rollers.
Transmission Series
This series is often applied on drives with slow to moderate speeds, lower chain loads and lengthy center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain variety is obtained by incorporating 2000 on the ASME/ANSI chain quantity and also the prefi x letter ?¡ãA?¡À. Note that some businesses don’t use a prefi x letter for this series so the chains might be represented as A2040, A2050 etc. or 2040, 2050 and so forth.
Conveyor Series with Standard (modest) Rollers
This series is often made use of on light to moderate load material handling conveyors with or without attachment backlinks. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and more substantial have ?¡ãHeavy?¡À series hyperlink plates (i.e. hyperlink plates of the up coming bigger chain size. The chain quantity is located by adding 2000 towards the ASME/ANSI chain number plus the prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À form side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Large (oversized) Rollers
These chains possess big rollers to ensure the chain rolls on a conveyor track cutting down friction. Chain numbers are found while in the exact same way as noted above except the last digit over the chain quantity is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the significant roller.
Sprockets
Usually sprockets should be produced specially for these chains according to your ASME/ANSI B29.three and B29.4 standards however, for Transmission Series and Conveyor Series with Typical (compact) Rollers, ASME/ANSI B29.1 Typical roller chain sprockets may be made use of presented the amount of teeth is thirty or far more.
