Double Pitch roller chains are generated in accordance together with the ASME/ANSI B29.three (Transmission Series) and B29.4 (Conveyor Series) American roller chain specifications. On the whole these chains are very similar to ASME/ANSI regular solutions except the pitch is double. They can be obtainable in Transmission Series, Conveyor Series with Conventional (little) Rollers and Conveyor Series with Massive (oversized) Rollers.
Transmission Series
This series is usually employed on drives with slow to reasonable speeds, minimal chain loads and extended center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain variety is obtained by incorporating 2000 on the ASME/ANSI chain number as well as prefi x letter ?¡ãA?¡À. Note that some organizations never use a prefi x letter for this series so the chains might be represented as A2040, A2050 and so on. or 2040, 2050 and so on.
Conveyor Series with Common (modest) Rollers
This series is usually employed on light to moderate load materials managing conveyors with or with no attachment links. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and more substantial have ?¡ãHeavy?¡À series link plates (i.e. hyperlink plates on the subsequent more substantial chain size. The chain number is found by adding 2000 to your ASME/ANSI chain amount as well as prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À form side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Substantial (oversized) Rollers
These chains possess large rollers so that the chain rolls on a conveyor track cutting down friction. Chain numbers are identified from the very same way as noted over except the last digit over the chain number is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the huge roller.
Sprockets
Usually sprockets should be generated specially for these chains in accordance to the ASME/ANSI B29.three and B29.four standards on the other hand, for Transmission Series and Conveyor Series with Standard (smaller) Rollers, ASME/ANSI B29.one Normal roller chain sprockets may perhaps be used provided the amount of teeth is 30 or additional.
