Double Pitch roller chains are generated in accordance with the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain specifications. Generally these chains are comparable to ASME/ANSI regular products except the pitch is double. They are really readily available in Transmission Series, Conveyor Series with Normal (small) Rollers and Conveyor Series with Big (oversized) Rollers.
Transmission Series
This series is usually used on drives with slow to moderate speeds, minimal chain loads and extended center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by adding 2000 to your ASME/ANSI chain quantity plus the 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 Standard (modest) Rollers
This series is often utilized on light to moderate load materials dealing with conveyors with or without the need of attachment hyperlinks. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and greater have ?¡ãHeavy?¡À series hyperlink plates (i.e. website link plates of the up coming more substantial chain dimension. The chain variety is discovered by adding 2000 on the ASME/ANSI chain variety as well as the prefi x letter ?¡ãC?¡À. Chains together with the ?¡ãheavy?¡À style side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Large (oversized) Rollers
These chains possess substantial rollers to ensure that the chain rolls on the conveyor track minimizing friction. Chain numbers are located from the same way as noted above except the last digit around the chain amount is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the massive roller.
Sprockets
Normally sprockets need to be created specially for these chains according to your ASME/ANSI B29.3 and B29.four specifications nonetheless, for Transmission Series and Conveyor Series with Common (smaller) Rollers, ASME/ANSI B29.one Normal roller chain sprockets may well be used provided the quantity of teeth is thirty or more.
