ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are developed in accordance using the ASME/ANSI B29.3 (Transmission Series) and B29.4 (Conveyor Series) American roller chain requirements. In general these chains are similar to ASME/ANSI normal items except the pitch is double. They’re out there in Transmission Series, Conveyor Series with Typical (little) Rollers and Conveyor Series with Substantial (oversized) Rollers.
Transmission Series
This series is usually utilized on drives with slow to reasonable speeds, low chain loads and prolonged center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by incorporating 2000 to the ASME/ANSI chain number as well as the prefi x letter ?¡ãA?¡À. Note that some organizations will not use a prefi x letter for this series so the chains might be represented as A2040, A2050 and so forth. or 2040, 2050 and so on.
Conveyor Series with Normal (smaller) Rollers
This series is often utilized on light to reasonable load material managing conveyors with or without attachment links. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and greater have ?¡ãHeavy?¡À series link plates (i.e. hyperlink plates with the upcoming greater chain size. The chain quantity is identified by including 2000 for the ASME/ANSI chain variety and the prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À style side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Large (oversized) Rollers
These chains possess large rollers to ensure that the chain rolls on a conveyor track lowering friction. Chain numbers are identified during the same way as mentioned over except that the last digit to the chain quantity is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the substantial roller.
Sprockets
On the whole sprockets ought to be made specially for these chains according to the ASME/ANSI B29.three and B29.four specifications even so, for Transmission Series and Conveyor Series with Conventional (tiny) Rollers, ASME/ANSI B29.one Regular roller chain sprockets may well be utilized offered the amount of teeth is thirty or a lot more.
