Double Pitch roller chains are made in accordance using the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain specifications. Usually these chains are very similar to ASME/ANSI conventional merchandise except the pitch is double. These are accessible in Transmission Series, Conveyor Series with Common (tiny) Rollers and Conveyor Series with Substantial (oversized) Rollers.
Transmission Series
This series is usually made use of on drives with slow to reasonable speeds, reduced chain loads and extended center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain number is obtained by incorporating 2000 on the ASME/ANSI chain number plus the prefi x letter ?¡ãA?¡À. Note that some corporations do not use a prefi x letter for this series so the chains might be represented as A2040, A2050 and so forth. or 2040, 2050 and so forth.
Conveyor Series with Typical (tiny) Rollers
This series is usually employed on light to moderate load materials dealing with conveyors with or without the need of attachment backlinks. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and larger have ?¡ãHeavy?¡À series website link plates (i.e. website link plates with the next larger chain dimension. The chain variety is identified by adding 2000 to the ASME/ANSI chain quantity plus the prefi x letter ?¡ãC?¡À. Chains with the ?¡ãheavy?¡À sort side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Big (oversized) Rollers
These chains possess huge rollers to ensure the chain rolls on the conveyor track decreasing friction. Chain numbers are identified during the exact same way as noted over except that the last digit around the chain number is changed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the big roller.
On the whole sprockets need to be generated specially for these chains in accordance to your ASME/ANSI B29.three and B29.4 standards nevertheless, for Transmission Series and Conveyor Series with Standard (modest) Rollers, ASME/ANSI Typical roller chain sprockets could be used provided the amount of teeth is 30 or more.
