Double Pitch roller chains are produced in accordance with the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain requirements. Normally these chains are related to ASME/ANSI regular merchandise except that the pitch is double. These are available in Transmission Series, Conveyor Series with Regular (small) Rollers and Conveyor Series with Large (oversized) Rollers.
Transmission Series
This series is usually utilized on drives with slow to moderate speeds, lower chain loads and lengthy center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain amount is obtained by including 2000 to your ASME/ANSI chain number and the prefi x letter ?¡ãA?¡À. Note that some firms tend not to use a prefi x letter for this series so the chains may well be represented as A2040, A2050 etc. or 2040, 2050 and so forth.
Conveyor Series with Normal (smaller) Rollers
This series is often employed on light to reasonable load material managing conveyors with or without having attachment hyperlinks. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and bigger have ?¡ãHeavy?¡À series hyperlink plates (i.e. link plates of your next greater chain size. The chain variety is discovered by adding 2000 towards the ASME/ANSI chain number plus the prefi x letter ?¡ãC?¡À. Chains with the ?¡ãheavy?¡À style side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Massive (oversized) Rollers
These chains possess huge rollers so that the chain rolls on the conveyor track lowering friction. Chain numbers are discovered while in the very same way as noted above except that the final digit within the chain variety is changed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the huge roller.
Sprockets
Usually sprockets ought to be produced specially for these chains according on the ASME/ANSI B29.3 and B29.4 standards even so, for Transmission Series and Conveyor Series with Common (compact) Rollers, ASME/ANSI B29.1 Conventional roller chain sprockets may perhaps be made use of provided the number of teeth is 30 or extra.
