ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are generated in accordance with the ASME/ANSI B29.3 (Transmission Series) and B29.4 (Conveyor Series) American roller chain standards. Normally these chains are related to ASME/ANSI conventional items except the pitch is double. They can be out there in Transmission Series, Conveyor Series with Standard (small) Rollers and Conveyor Series with Significant (oversized) Rollers.
Transmission Series
This series is often applied on drives with slow to reasonable speeds, reduced chain loads and prolonged center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by incorporating 2000 to your ASME/ANSI chain quantity and also the prefi x letter ?¡ãA?¡À. Note that some providers do not use a prefi x letter for this series so the chains may possibly be represented as A2040, A2050 and so on. or 2040, 2050 etc.
Conveyor Series with Regular (modest) Rollers
This series is often employed on light to moderate load materials managing conveyors with or without having attachment back links. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and more substantial have ?¡ãHeavy?¡À series link plates (i.e. link plates in the next bigger chain size. The chain quantity is located by incorporating 2000 towards the ASME/ANSI chain quantity as well as the prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À type side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Significant (oversized) Rollers
These chains possess huge rollers in order that the chain rolls on a conveyor track decreasing friction. Chain numbers are located from the identical way as noted above except that the last digit around the chain variety is changed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the large roller.
Sprockets
Normally sprockets need to be generated specially for these chains according to the ASME/ANSI B29.3 and B29.four requirements however, for Transmission Series and Conveyor Series with Common (modest) Rollers, ASME/ANSI B29.1 Standard roller chain sprockets could be utilized provided the number of teeth is thirty or much more.
