ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are produced in accordance together with the ASME/ANSI B29.three (Transmission Series) and B29.4 (Conveyor Series) American roller chain standards. Normally these chains are comparable to ASME/ANSI regular items except the pitch is double. They may be obtainable in Transmission Series, Conveyor Series with Standard (small) Rollers and Conveyor Series with Massive (oversized) Rollers.
Transmission Series
This series is usually used on drives with slow to reasonable speeds, very low chain loads and extended center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by including 2000 towards the ASME/ANSI chain quantity and also the prefi x letter ?¡ãA?¡À. Note that some firms usually do not use a prefi x letter for this series so the chains may perhaps be represented as A2040, A2050 and so on. or 2040, 2050 and so forth.
Conveyor Series with Conventional (compact) Rollers
This series is often employed on light to moderate load materials managing conveyors with or without attachment hyperlinks. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and greater have ?¡ãHeavy?¡À series link plates (i.e. hyperlink plates with the next bigger chain size. The chain amount is located by including 2000 for the ASME/ANSI chain amount as well as the prefi x letter ?¡ãC?¡À. Chains with the ?¡ãheavy?¡À sort side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Significant (oversized) Rollers
These chains possess huge rollers so that the chain rolls on the conveyor track lowering friction. Chain numbers are located inside the similar way as mentioned above except the final digit within the chain variety is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the massive roller.
Sprockets
On the whole sprockets need to be developed specially for these chains in accordance for the ASME/ANSI B29.3 and B29.four standards nonetheless, for Transmission Series and Conveyor Series with Common (little) Rollers, ASME/ANSI B29.one Regular roller chain sprockets could be made use of offered the amount of teeth is thirty or extra.
