ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are created in accordance with the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain standards. In general these chains are equivalent to ASME/ANSI conventional items except the pitch is double. They can be readily available in Transmission Series, Conveyor Series with Typical (small) Rollers and Conveyor Series with Huge (oversized) Rollers.
Transmission Series
This series is usually applied on drives with slow to reasonable speeds, lower chain loads and lengthy center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain number is obtained by including 2000 on the ASME/ANSI chain amount as well as the prefi x letter ?¡ãA?¡À. Note that some companies don’t use a prefi x letter for this series so the chains might be represented as A2040, A2050 etc. or 2040, 2050 etc.
Conveyor Series with Standard (compact) Rollers
This series is often utilised on light to reasonable load materials handling conveyors with or with out 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. website link plates in the next larger chain dimension. The chain number is discovered by including 2000 on the ASME/ANSI chain number and also 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 substantial rollers in order that the chain rolls on a conveyor track cutting down friction. Chain numbers are discovered during the same way as mentioned above except that the last digit about the chain quantity is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the big roller.
On the whole sprockets must be made specially for these chains in accordance to the ASME/ANSI B29.3 and B29.four requirements on the other hand, for Transmission Series and Conveyor Series with Regular (small) Rollers, ASME/ANSI Typical roller chain sprockets might be applied presented the quantity of teeth is thirty or a lot more.
