Double Pitch roller chains are produced in accordance with the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain specifications. In general these chains are comparable to ASME/ANSI regular merchandise except that the pitch is double. They may be out there in Transmission Series, Conveyor Series with Regular (small) Rollers and Conveyor Series with Significant (oversized) Rollers.
Transmission Series
This series is usually applied on drives with slow to reasonable speeds, lower chain loads and prolonged center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by including 2000 to the ASME/ANSI chain quantity and also the 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 on. or 2040, 2050 etc.
Conveyor Series with Normal (little) Rollers
This series is usually utilised on light to reasonable load materials dealing with conveyors with or with no attachment back links. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and bigger have ?¡ãHeavy?¡À series website link plates (i.e. hyperlink plates from the following larger chain size. The chain amount is identified by incorporating 2000 for the ASME/ANSI chain quantity as well as prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À form side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Massive (oversized) Rollers
These chains possess significant rollers to ensure the chain rolls on a conveyor track minimizing friction. Chain numbers are discovered in the similar way as noted over except the last digit on the chain number is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the massive roller.
Sprockets
In general sprockets should be developed specially for these chains according towards the ASME/ANSI B29.3 and B29.4 specifications having said that, for Transmission Series and Conveyor Series with Standard (compact) Rollers, ASME/ANSI B29.1 Common roller chain sprockets may possibly be applied supplied the amount of teeth is thirty or extra.
