ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are developed in accordance using the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain specifications. In general these chains are very similar to ASME/ANSI typical products except that the pitch is double. They are really out there in Transmission Series, Conveyor Series with Common (modest) Rollers and Conveyor Series with Big (oversized) Rollers.
Transmission Series
This series is often utilised on drives with slow to moderate speeds, minimal chain loads and long center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain variety is obtained by adding 2000 to your ASME/ANSI chain variety plus the prefi x letter ?¡ãA?¡À. Note that some companies do not use a prefi x letter for this series so the chains could be represented as A2040, A2050 etc. or 2040, 2050 and so on.
Conveyor Series with Normal (tiny) Rollers
This series is usually made use of on light to reasonable load material dealing with 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 hyperlink plates (i.e. link plates from the following more substantial chain dimension. The chain number is found by adding 2000 to the ASME/ANSI chain number as well as prefi x letter ?¡ãC?¡À. Chains together with the ?¡ãheavy?¡À style side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Massive (oversized) Rollers
These chains possess large rollers to ensure the chain rolls on a conveyor track reducing friction. Chain numbers are discovered in the identical way as noted over except that the last digit on the chain quantity is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the large roller.
Sprockets
Generally sprockets must be created specially for these chains according to your ASME/ANSI B29.three and B29.4 requirements having said that, for Transmission Series and Conveyor Series with Regular (smaller) Rollers, ASME/ANSI B29.1 Conventional roller chain sprockets may perhaps be employed provided the number of teeth is 30 or a lot more.
