ASME/ANSI Transmission Series Double Pitch Roller Chain

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. On the whole these chains are related to ASME/ANSI conventional products except the pitch is double. They can be readily available in Transmission Series, Conveyor Series with Regular (modest) Rollers and Conveyor Series with Significant (oversized) Rollers.
Transmission Series
This series is usually utilised on drives with slow to moderate speeds, minimal chain loads and lengthy center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by adding 2000 to the ASME/ANSI chain number plus the prefi x letter ?¡ãA?¡À. Note that some companies do not 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 Regular (smaller) Rollers
This series is often made use of on light to reasonable load material handling conveyors with or devoid of attachment hyperlinks. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and greater have ?¡ãHeavy?¡À series website link plates (i.e. link plates in the subsequent more substantial chain size. The chain variety is uncovered by including 2000 to the ASME/ANSI chain quantity and the prefi x letter ?¡ãC?¡À. Chains with the ?¡ãheavy?¡À form side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Big (oversized) Rollers
These chains possess huge rollers to ensure that the chain rolls on the conveyor track minimizing friction. Chain numbers are found inside the similar way as mentioned over except the last digit about the chain variety is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the significant roller.
スプロケット
Generally sprockets ought to be generated specially for these chains in accordance for the ASME/ANSI B29.three and B29.four standards having said that, for Transmission Series and Conveyor Series with Common (smaller) Rollers, ASME/ANSI B29.one Typical roller chain sprockets may well be utilized supplied the amount of teeth is 30 or a lot more.
