Double Pitch roller chains are produced in accordance using the ASME/ANSI B29.three (Transmission Series) and B29.4 (Conveyor Series) American roller chain requirements. Generally these chains are related to ASME/ANSI common products except the pitch is double. They are really out there in Transmission Series, Conveyor Series with Typical (compact) Rollers and Conveyor Series with Big (oversized) Rollers.
Transmission Series
This series is usually used on drives with slow to reasonable speeds, very low chain loads and lengthy center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain variety is obtained by incorporating 2000 for the ASME/ANSI chain variety and the prefi x letter ?¡ãA?¡À. Note that some businesses never use a prefi x letter for this series so the chains may possibly be represented as A2040, A2050 and so forth. or 2040, 2050 and so forth.
Conveyor Series with Typical (compact) Rollers
This series is often employed on light to reasonable load material dealing with conveyors with or without having attachment backlinks. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and more substantial have ?¡ãHeavy?¡À series hyperlink plates (i.e. link plates in the subsequent more substantial chain dimension. The chain amount is found by including 2000 on the ASME/ANSI chain variety as well as prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À style side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Big (oversized) Rollers
These chains possess big rollers to ensure the chain rolls on a conveyor track decreasing friction. Chain numbers are observed within the very same way as noted over except that the final digit to the chain amount is changed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the substantial roller.
Sprockets
In general sprockets need to be produced specially for these chains according to the ASME/ANSI B29.3 and B29.four specifications however, for Transmission Series and Conveyor Series with Standard (little) Rollers, ASME/ANSI B29.one Common roller chain sprockets might be utilized presented the quantity of teeth is 30 or far more.
