Double Pitch roller chains are produced in accordance with the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain standards. In general these chains are equivalent to ASME/ANSI conventional solutions except that the pitch is double. They are available in Transmission Series, Conveyor Series with Conventional (tiny) Rollers and Conveyor Series with Large (oversized) Rollers.
Transmission Series
This series is usually utilised on drives with slow to moderate speeds, very low chain loads and lengthy center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain number is obtained by adding 2000 for the ASME/ANSI chain number and the prefi x letter ?¡ãA?¡À. Note that some providers never use a prefi x letter for this series so the chains could be represented as A2040, A2050 and so on. or 2040, 2050 and so forth.
Conveyor Series with Normal (smaller) Rollers
This series is often applied on light to moderate load material handling conveyors with or without attachment links. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and bigger have ?¡ãHeavy?¡À series website link plates (i.e. hyperlink plates on the following greater chain dimension. The chain number is discovered by including 2000 on the ASME/ANSI chain variety and also 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 Substantial (oversized) Rollers
These chains possess huge rollers in order that the chain rolls on the conveyor track reducing friction. Chain numbers are uncovered inside the identical way as noted above except that the last digit on the chain number is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the big roller.
Sprockets
In general sprockets ought to be created specially for these chains according towards the ASME/ANSI B29.three and B29.4 specifications even so, for Transmission Series and Conveyor Series with Common (little) Rollers, ASME/ANSI B29.one Common roller chain sprockets could be utilised presented the amount of teeth is 30 or much more.
