Double Pitch roller chains are developed in accordance together with the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain requirements. Usually these chains are very similar to ASME/ANSI standard solutions except that the pitch is double. They can be obtainable in Transmission Series, Conveyor Series with Regular (smaller) Rollers and Conveyor Series with Significant (oversized) Rollers.
Transmission Series
This series is often applied on drives with slow to reasonable speeds, low chain loads and lengthy 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 as well as the prefi x letter ?¡ãA?¡À. Note that some organizations never use a prefi x letter for this series so the chains may possibly be represented as A2040, A2050 and so forth. or 2040, 2050 and so forth.
Conveyor Series with Typical (little) Rollers
This series is usually made use of on light to reasonable load material handling conveyors with or with no attachment links. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and bigger have ?¡ãHeavy?¡À series link plates (i.e. hyperlink plates with the next greater chain size. The chain quantity is uncovered by incorporating 2000 towards the ASME/ANSI chain quantity and the prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À variety side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Substantial (oversized) Rollers
These chains possess massive rollers so that the chain rolls on a conveyor track decreasing friction. Chain numbers are discovered inside the similar way as mentioned above except the final digit over the chain number is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the big roller.
In general sprockets must be generated specially for these chains in accordance for the ASME/ANSI B29.3 and B29.4 requirements however, for Transmission Series and Conveyor Series with Regular (tiny) Rollers, ASME/ANSI B29.1 Standard roller chain sprockets could be made use of presented the amount of teeth is thirty or additional.
