Double Pitch roller chains are developed in accordance with all the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain standards. Usually these chains are comparable to ASME/ANSI common items except that the pitch is double. They are really out there in Transmission Series, Conveyor Series with Regular (compact) Rollers and Conveyor Series with Significant (oversized) Rollers.
Transmission Series
This series is often employed on drives with slow to reasonable speeds, low chain loads and prolonged center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain number is obtained by including 2000 for the ASME/ANSI chain number along with the prefi x letter ?¡ãA?¡À. Note that some companies will not use a prefi x letter for this series so the chains may well be represented as A2040, A2050 etc. or 2040, 2050 and so forth.
Conveyor Series with Standard (compact) Rollers
This series is often utilized on light to reasonable load material dealing with conveyors with or without having attachment hyperlinks. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and more substantial have ?¡ãHeavy?¡À series link plates (i.e. hyperlink plates from the up coming more substantial chain dimension. The chain quantity is identified by adding 2000 for the ASME/ANSI chain amount plus the prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À type side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Big (oversized) Rollers
These chains possess big rollers to ensure that the chain rolls on a conveyor track cutting down friction. Chain numbers are uncovered in the very same way as mentioned over except that the last digit within the chain number is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the significant roller.
Sprockets
Usually sprockets must be produced specially for these chains according on the ASME/ANSI B29.3 and B29.4 requirements nonetheless, for Transmission Series and Conveyor Series with Standard (tiny) Rollers, ASME/ANSI B29.one Conventional roller chain sprockets could be utilised presented the amount of teeth is thirty or much more.
