Double Pitch roller chains are produced in accordance together with the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain specifications. Usually these chains are comparable to ASME/ANSI typical goods except that the pitch is double. They’re obtainable in Transmission Series, Conveyor Series with Common (compact) Rollers and Conveyor Series with Big (oversized) Rollers.
Transmission Series
This series is often employed on drives with slow to reasonable speeds, minimal chain loads and long center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain variety is obtained by adding 2000 for the ASME/ANSI chain quantity and also the prefi x letter ?¡ãA?¡À. Note that some providers do not use a prefi x letter for this series so the chains may be represented as A2040, A2050 and so forth. or 2040, 2050 etc.
Conveyor Series with Typical (modest) Rollers
This series is usually employed on light to reasonable load materials managing conveyors with or without the need of attachment links. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and bigger have ?¡ãHeavy?¡À series hyperlink plates (i.e. hyperlink plates from the upcoming more substantial chain size. The chain variety is uncovered by adding 2000 for the ASME/ANSI chain variety and the prefi x letter ?¡ãC?¡À. Chains together with the ?¡ãheavy?¡À variety side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Large (oversized) Rollers
These chains possess massive rollers to ensure that the chain rolls on a conveyor track minimizing friction. Chain numbers are found from the similar way as noted over except that the final digit around the chain number is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the large roller.
Sprockets
Normally sprockets needs to be created specially for these chains in accordance to your ASME/ANSI B29.3 and B29.four standards even so, for Transmission Series and Conveyor Series with Conventional (compact) Rollers, ASME/ANSI B29.1 Normal roller chain sprockets may be employed offered the quantity of teeth is thirty or more.
