Double Pitch roller chains are produced in accordance with all the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain specifications. Normally these chains are comparable to ASME/ANSI common items except that the pitch is double. They can be readily available in Transmission Series, Conveyor Series with Normal (tiny) Rollers and Conveyor Series with Large (oversized) Rollers.
Transmission Series
This series is often utilised on drives with slow to reasonable speeds, low chain loads and extended center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain amount is obtained by adding 2000 towards the ASME/ANSI chain amount as well as the prefi x letter ?¡ãA?¡À. Note that some organizations don’t use a prefi x letter for this series so the chains may possibly be represented as A2040, A2050 and so on. or 2040, 2050 and so forth.
Conveyor Series with Common (compact) Rollers
This series is usually made use of on light to moderate load material dealing with conveyors with or without the need of attachment back links. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and greater have ?¡ãHeavy?¡À series link plates (i.e. website link plates of the following more substantial chain size. The chain quantity is found by incorporating 2000 on the ASME/ANSI chain amount along with the prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À sort side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Big (oversized) Rollers
These chains possess huge rollers so that the chain rolls on the conveyor track decreasing friction. Chain numbers are located while in the very same way as mentioned over except the last digit over the chain variety is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the significant roller.
On the whole sprockets must be generated specially for these chains according on the ASME/ANSI B29.three and B29.4 standards on the other hand, for Transmission Series and Conveyor Series with Standard (tiny) Rollers, ASME/ANSI Regular roller chain sprockets may possibly be employed supplied the quantity of teeth is thirty or far more.
