Double Pitch roller chains are developed in accordance using the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain specifications. Generally these chains are very similar to ASME/ANSI regular products except that the pitch is double. They may be accessible in Transmission Series, Conveyor Series with Normal (smaller) Rollers and Conveyor Series with Large (oversized) Rollers.
Transmission Series
This series is often utilized on drives with slow to moderate speeds, very low chain loads and prolonged center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by adding 2000 to the ASME/ANSI chain amount plus the prefi x letter ?¡ãA?¡À. Note that some organizations do not use a prefi x letter for this series so the chains may be represented as A2040, A2050 etc. or 2040, 2050 and so forth.
Conveyor Series with Standard (smaller) Rollers
This series is usually used on light to moderate load materials managing conveyors with or with out attachment back links. 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. website link plates on the up coming larger chain dimension. The chain quantity is found by incorporating 2000 towards the ASME/ANSI chain quantity and the prefi x letter ?¡ãC?¡À. Chains with the ?¡ãheavy?¡À form side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Substantial (oversized) Rollers
These chains possess huge rollers in order that the chain rolls on the conveyor track decreasing friction. Chain numbers are observed within the very same way as noted above except that the last digit over the chain quantity is changed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the massive roller.
Sprockets
Generally sprockets must be developed specially for these chains in accordance to your ASME/ANSI B29.3 and B29.4 requirements even so, for Transmission Series and Conveyor Series with Typical (little) Rollers, ASME/ANSI B29.one Normal roller chain sprockets may well be employed supplied the quantity of teeth is 30 or additional.
