Double Pitch roller chains are made in accordance together with the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain specifications. Generally these chains are equivalent to ASME/ANSI normal products except the pitch is double. These are accessible in Transmission Series, Conveyor Series with Typical (compact) Rollers and Conveyor Series with Large (oversized) Rollers.
Transmission Series
This series is often applied on drives with slow to reasonable speeds, lower chain loads and lengthy center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by including 2000 to your ASME/ANSI chain amount as well as prefi x letter ?¡ãA?¡À. Note that some firms 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 forth.
Conveyor Series with Conventional (little) Rollers
This series is often utilised on light to reasonable load material handling conveyors with or with out attachment hyperlinks. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and larger have ?¡ãHeavy?¡À series hyperlink plates (i.e. link plates in the upcoming more substantial chain size. The chain quantity is found by including 2000 for the ASME/ANSI chain amount as well as the prefi x letter ?¡ãC?¡À. Chains with the ?¡ãheavy?¡À kind side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Big (oversized) Rollers
These chains possess big rollers to ensure that the chain rolls on the conveyor track cutting down friction. Chain numbers are found while in the similar way as mentioned above except that the last digit on the chain amount is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the substantial roller.
Normally sprockets should be produced specially for these chains in accordance to the ASME/ANSI B29.3 and B29.4 requirements however, for Transmission Series and Conveyor Series with Regular (smaller) Rollers, ASME/ANSI Regular roller chain sprockets could be applied supplied the amount of teeth is 30 or additional.
