Double Pitch roller chains are produced in accordance with the ASME/ANSI B29.three (Transmission Series) and B29.4 (Conveyor Series) American roller chain standards. Usually these chains are similar to ASME/ANSI regular solutions except the pitch is double. These are obtainable in Transmission Series, Conveyor Series with Conventional (tiny) Rollers and Conveyor Series with Massive (oversized) Rollers.
Transmission Series
This series is usually utilised on drives with slow to reasonable speeds, lower chain loads and extended center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain variety is obtained by incorporating 2000 to your ASME/ANSI chain number and the prefi x letter ?¡ãA?¡À. Note that some firms never use a prefi x letter for this series so the chains could be represented as A2040, A2050 and so on. or 2040, 2050 and so on.
Conveyor Series with Typical (smaller) Rollers
This series is often employed on light to moderate load materials managing conveyors with or devoid of attachment hyperlinks. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and more substantial have ?¡ãHeavy?¡À series hyperlink plates (i.e. website link plates on the up coming larger chain size. The chain number is discovered by adding 2000 to the ASME/ANSI chain variety and the prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À style side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Substantial (oversized) Rollers
These chains possess large rollers so that the chain rolls on a conveyor track reducing friction. Chain numbers are located during the very same way as noted above except that the final digit on the chain number is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the massive roller.
Sprockets
In general sprockets ought to be produced specially for these chains in accordance towards the ASME/ANSI B29.three and B29.four standards having said that, for Transmission Series and Conveyor Series with Regular (compact) Rollers, ASME/ANSI B29.1 Common roller chain sprockets may be utilized provided the amount of teeth is 30 or extra.
