Double Pitch roller chains are made in accordance using the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain requirements. In general these chains are equivalent to ASME/ANSI common goods except that the pitch is double. They are readily available in Transmission Series, Conveyor Series with Regular (smaller) Rollers and Conveyor Series with Significant (oversized) Rollers.
Transmission Series
This series is often made use of on drives with slow to moderate speeds, very low chain loads and long center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by adding 2000 to the ASME/ANSI chain amount as well as the prefi x letter ?¡ãA?¡À. Note that some providers don’t use a prefi x letter for this series so the chains may well be represented as A2040, A2050 and so forth. or 2040, 2050 and so forth.
Conveyor Series with Standard (small) Rollers
This series is often applied on light to reasonable load material handling conveyors with or without attachment backlinks. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and bigger have ?¡ãHeavy?¡À series website link plates (i.e. link plates of your following bigger chain dimension. The chain amount is located by including 2000 towards the ASME/ANSI chain number as well as the prefi x letter ?¡ãC?¡À. Chains together with the ?¡ãheavy?¡À kind side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Large (oversized) Rollers
These chains possess huge rollers in order that the chain rolls on the conveyor track lowering friction. Chain numbers are uncovered within the same way as mentioned above except that the final digit within the chain quantity is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the significant roller.
Sprockets
Generally sprockets must be created specially for these chains according on the ASME/ANSI B29.3 and B29.4 requirements nevertheless, for Transmission Series and Conveyor Series with Common (little) Rollers, ASME/ANSI B29.1 Conventional roller chain sprockets could be utilised supplied the quantity of teeth is thirty or much more.
