Double Pitch roller chains are created in accordance with the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain specifications. On the whole these chains are related to ASME/ANSI typical items except that the pitch is double. They can be available in Transmission Series, Conveyor Series with Normal (tiny) Rollers and Conveyor Series with Substantial (oversized) Rollers.
Transmission Series
This series is usually applied on drives with slow to reasonable speeds, low chain loads and lengthy center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain variety is obtained by including 2000 on the ASME/ANSI chain number along with the prefi x letter ?¡ãA?¡À. Note that some corporations never use a prefi x letter for this series so the chains may be represented as A2040, A2050 and so on. or 2040, 2050 and so forth.
Conveyor Series with Common (little) Rollers
This series is usually utilized on light to moderate load materials dealing with conveyors with or devoid of 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. website link plates with the next more substantial chain size. The chain variety is discovered by adding 2000 to the ASME/ANSI chain quantity along with the prefi x letter ?¡ãC?¡À. Chains together with the ?¡ãheavy?¡À kind side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Large (oversized) Rollers
These chains possess big rollers in order that the chain rolls on the conveyor track reducing friction. Chain numbers are discovered during the exact same way as noted above except that the final digit on the chain number is changed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the large roller.
Normally sprockets really should be generated specially for these chains according on the ASME/ANSI B29.three and B29.four standards however, for Transmission Series and Conveyor Series with Conventional (tiny) Rollers, ASME/ANSI Common roller chain sprockets might be made use of presented the amount of teeth is thirty or more.
