Double Pitch roller chains are developed in accordance together with the ASME/ANSI B29.three (Transmission Series) and B29.4 (Conveyor Series) American roller chain standards. In general these chains are equivalent to ASME/ANSI standard goods except that the pitch is double. They may be available in Transmission Series, Conveyor Series with Normal (smaller) Rollers and Conveyor Series with Significant (oversized) Rollers.
Transmission Series
This series is often utilised on drives with slow to reasonable speeds, reduced chain loads and extended center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain amount is obtained by adding 2000 for the ASME/ANSI chain number and also the prefi x letter ?¡ãA?¡À. Note that some businesses tend not to use a prefi x letter for this series so the chains might be represented as A2040, A2050 and so on. or 2040, 2050 and so on.
Conveyor Series with Common (smaller) Rollers
This series is usually applied on light to moderate load material 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 larger have ?¡ãHeavy?¡À series website link plates (i.e. website link plates in the up coming more substantial chain size. The chain variety is identified by adding 2000 towards the ASME/ANSI chain quantity as well as the prefi x letter ?¡ãC?¡À. Chains with the ?¡ãheavy?¡À kind side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Huge (oversized) Rollers
These chains possess substantial rollers so that the chain rolls on a conveyor track lowering friction. Chain numbers are discovered inside the exact same way as mentioned above except the final digit within the chain number is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the huge roller.
Generally sprockets must 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 (modest) Rollers, ASME/ANSI Common roller chain sprockets may be employed offered the amount of teeth is 30 or much more.
