Double Pitch roller chains are generated in accordance using the ASME/ANSI B29.three (Transmission Series) and B29.4 (Conveyor Series) American roller chain requirements. Generally these chains are equivalent to ASME/ANSI common solutions except that the pitch is double. They may be offered in Transmission Series, Conveyor Series with Typical (modest) Rollers and Conveyor Series with Big (oversized) Rollers.
Transmission Series
This series is often applied on drives with slow to moderate speeds, minimal chain loads and lengthy center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain variety is obtained by adding 2000 to the ASME/ANSI chain number and the prefi x letter ?¡ãA?¡À. Note that some providers will not use a prefi x letter for this series so the chains may perhaps be represented as A2040, A2050 and so on. or 2040, 2050 and so forth.
Conveyor Series with Typical (compact) Rollers
This series is often used on light to reasonable load material managing conveyors with or with no attachment hyperlinks. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and more substantial have ?¡ãHeavy?¡À series hyperlink plates (i.e. website link plates of your subsequent bigger chain dimension. The chain number is uncovered by including 2000 to the ASME/ANSI chain amount along with the prefi x letter ?¡ãC?¡À. Chains with the ?¡ãheavy?¡À form side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Large (oversized) Rollers
These chains possess substantial rollers to ensure the chain rolls on a conveyor track cutting down friction. Chain numbers are found during the exact same way as noted over except that the final digit within the chain quantity is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the significant roller.
Generally sprockets must be created specially for these chains in accordance to the ASME/ANSI B29.three and B29.4 requirements however, for Transmission Series and Conveyor Series with Common (modest) Rollers, ASME/ANSI Common roller chain sprockets might be employed supplied the amount of teeth is 30 or extra.
