Double Pitch roller chains are generated in accordance with the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain specifications. Usually these chains are very similar to ASME/ANSI normal merchandise except that the pitch is double. They may be out there in Transmission Series, Conveyor Series with Typical (modest) Rollers and Conveyor Series with Large (oversized) Rollers.
Transmission Series
This series is often employed on drives with slow to moderate speeds, reduced chain loads and long center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain number is obtained by incorporating 2000 to your ASME/ANSI chain variety and also the prefi x letter ?¡ãA?¡À. Note that some businesses usually do 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 forth.
Conveyor Series with Conventional (modest) Rollers
This series is often utilized on light to reasonable load material handling conveyors with or with no attachment backlinks. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and bigger have ?¡ãHeavy?¡À series link plates (i.e. website link plates in the upcoming more substantial chain size. The chain variety is discovered by adding 2000 to the ASME/ANSI chain amount and the prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À kind side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Massive (oversized) Rollers
These chains possess massive rollers to ensure the chain rolls on a conveyor track cutting down friction. Chain numbers are observed while in the similar way as noted above except the final digit to the chain quantity is changed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the substantial roller.
On the whole sprockets needs to be generated specially for these chains in accordance to the ASME/ANSI B29.three and B29.4 requirements even so, for Transmission Series and Conveyor Series with Common (smaller) Rollers, ASME/ANSI B29.1 Regular roller chain sprockets could be used supplied the number of teeth is thirty or far more.
