Double Pitch roller chains are produced in accordance with the ASME/ANSI B29.three (Transmission Series) and B29.4 (Conveyor Series) American roller chain standards. Normally these chains are equivalent to ASME/ANSI standard goods except the pitch is double. They are really obtainable in Transmission Series, Conveyor Series with Common (smaller) Rollers and Conveyor Series with Huge (oversized) Rollers.
Transmission Series
This series is usually utilized on drives with slow to reasonable speeds, low chain loads and extended center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by adding 2000 for the ASME/ANSI chain quantity plus the prefi x letter ?¡ãA?¡À. Note that some organizations tend not to use a prefi x letter for this series so the chains may well be represented as A2040, A2050 and so on. or 2040, 2050 and so forth.
Conveyor Series with Regular (tiny) Rollers
This series is usually utilised on light to reasonable load material handling conveyors with or devoid 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 website link plates (i.e. link plates of your up coming bigger chain size. The chain quantity is identified by adding 2000 towards the ASME/ANSI chain quantity plus 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 huge rollers to ensure that the chain rolls on a conveyor track minimizing friction. Chain numbers are discovered during the similar way as noted above except the last digit around the chain amount is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the huge roller.
Normally sprockets ought to be produced specially for these chains in accordance to your ASME/ANSI B29.3 and B29.four standards even so, for Transmission Series and Conveyor Series with Standard (tiny) Rollers, ASME/ANSI Normal roller chain sprockets could be utilized offered the amount of teeth is 30 or additional.
