Double Pitch roller chains are made in accordance with all the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain requirements. In general these chains are related to ASME/ANSI typical items except the pitch is double. They can be obtainable in Transmission Series, Conveyor Series with Typical (compact) Rollers and Conveyor Series with Massive (oversized) Rollers.
This series is usually employed on drives with slow to moderate speeds, lower chain loads and long center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain amount is obtained by adding 2000 for the ASME/ANSI chain quantity as well as the prefi x letter ?¡ãA?¡À. Note that some providers tend not to use a prefi x letter for this series so the chains may possibly be represented as A2040, A2050 and so on. or 2040, 2050 and so forth.
Conveyor Series with Typical (little) Rollers
This series is usually used on light to moderate load material dealing with conveyors with or without having attachment backlinks. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and larger have ?¡ãHeavy?¡À series link plates (i.e. hyperlink plates in the upcoming bigger chain dimension. The chain number is identified by adding 2000 to the ASME/ANSI chain amount as well as prefi x letter ?¡ãC?¡À. Chains together with the ?¡ãheavy?¡À style side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Significant (oversized) Rollers
These chains possess massive rollers in order that the chain rolls on the conveyor track decreasing friction. Chain numbers are identified inside the very same way as mentioned over except the last digit about the chain quantity is changed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the substantial roller.
On the whole sprockets should be developed specially for these chains in accordance to the ASME/ANSI B29.3 and B29.four specifications on the other hand, for Transmission Series and Conveyor Series with Normal (compact) Rollers, ASME/ANSI B29.1 Normal roller chain sprockets may perhaps be utilised presented the amount of teeth is thirty or much more.
