Double Pitch roller chains are produced in accordance together with the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain requirements. On the whole these chains are related to ASME/ANSI conventional products except that the pitch is double. They are really obtainable in Transmission Series, Conveyor Series with Typical (modest) Rollers and Conveyor Series with Big (oversized) Rollers.
Transmission Series
This series is usually made use of on drives with slow to moderate speeds, very low chain loads and prolonged center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by incorporating 2000 to the ASME/ANSI chain variety along with the prefi x letter ?¡ãA?¡À. Note that some companies tend not to use a prefi x letter for this series so the chains may possibly be represented as A2040, A2050 etc. or 2040, 2050 and so forth.
Conveyor Series with Standard (smaller) Rollers
This series is usually employed on light to reasonable load material managing conveyors with or with out attachment hyperlinks. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and larger have ?¡ãHeavy?¡À series hyperlink plates (i.e. hyperlink plates in the following more substantial chain size. The chain amount is identified by including 2000 to the ASME/ANSI chain variety as well as 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 Massive (oversized) Rollers
These chains possess massive rollers to ensure the chain rolls on the conveyor track decreasing friction. Chain numbers are identified inside the exact same way as noted over except that the last digit to the chain number is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the big roller.
Sprockets
Generally sprockets needs to be created specially for these chains in accordance to the ASME/ANSI B29.three and B29.four standards nevertheless, for Transmission Series and Conveyor Series with Typical (little) Rollers, ASME/ANSI B29.1 Common roller chain sprockets may possibly be utilized supplied the quantity of teeth is thirty or a lot more.
