Double Pitch roller chains are developed in accordance using the ASME/ANSI B29.3 (Transmission Series) and B29.4 (Conveyor Series) American roller chain specifications. On the whole these chains are similar to ASME/ANSI common solutions except the pitch is double. These are out there in Transmission Series, Conveyor Series with Regular (modest) Rollers and Conveyor Series with Large (oversized) Rollers.
Transmission Series
This series is usually made use of on drives with slow to moderate speeds, reduced chain loads and prolonged center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain amount is obtained by incorporating 2000 to the ASME/ANSI chain number 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 may well be represented as A2040, A2050 and so forth. or 2040, 2050 and so forth.
Conveyor Series with Regular (tiny) Rollers
This series is usually used on light to moderate load material managing conveyors with or devoid of attachment back links. 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 of your following greater chain size. The chain amount is observed by incorporating 2000 to your ASME/ANSI chain amount as well as prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À kind side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Significant (oversized) Rollers
These chains possess large rollers to ensure that the chain rolls on the conveyor track reducing friction. Chain numbers are observed within the identical way as noted over except the final digit on the chain amount is changed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the significant roller.
Sprockets
In general sprockets should be produced specially for these chains according on the ASME/ANSI B29.three and B29.4 standards nevertheless, for Transmission Series and Conveyor Series with Typical (modest) Rollers, ASME/ANSI B29.1 Regular roller chain sprockets may perhaps be made use of supplied the amount of teeth is 30 or extra.
