Double Pitch roller chains are produced in accordance using the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain requirements. Usually these chains are similar to ASME/ANSI standard merchandise except that the pitch is double. They may be readily available in Transmission Series, Conveyor Series with Normal (tiny) Rollers and Conveyor Series with Substantial (oversized) Rollers.
Transmission Series
This series is usually utilized on drives with slow to reasonable speeds, reduced chain loads and long center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain number is obtained by incorporating 2000 for the ASME/ANSI chain number along with the prefi x letter ?¡ãA?¡À. Note that some businesses don’t use a prefi x letter for this series so the chains may well be represented as A2040, A2050 etc. or 2040, 2050 and so on.
Conveyor Series with Normal (smaller) Rollers
This series is usually used on light to reasonable load material managing conveyors with or devoid of attachment links. 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. website link plates of the up coming bigger chain dimension. The chain variety is located by incorporating 2000 to the ASME/ANSI chain quantity and the prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À form side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Significant (oversized) Rollers
These chains possess substantial rollers to ensure the chain rolls on a conveyor track lowering friction. Chain numbers are located within the identical way as noted over except the final digit to the chain number is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the huge roller.
In general sprockets really should be developed specially for these chains according on the ASME/ANSI B29.three and B29.4 specifications even so, for Transmission Series and Conveyor Series with Conventional (tiny) Rollers, ASME/ANSI B29.1 Conventional roller chain sprockets may be utilized presented the number of teeth is thirty or much more.
