ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are created in accordance with the ASME/ANSI B29.3 (Transmission Series) and B29.4 (Conveyor Series) American roller chain standards. On the whole these chains are similar to ASME/ANSI normal goods except the pitch is double. They can be out there in Transmission Series, Conveyor Series with Normal (compact) Rollers and Conveyor Series with Substantial (oversized) Rollers.
Transmission Series
This series is usually made use of on drives with slow to moderate speeds, minimal chain loads and prolonged center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain variety is obtained by adding 2000 towards the ASME/ANSI chain variety plus the prefi x letter ?¡ãA?¡À. Note that some organizations will not use a prefi x letter for this series so the chains may perhaps be represented as A2040, A2050 etc. or 2040, 2050 and so forth.
Conveyor Series with Normal (modest) Rollers
This series is usually utilised on light to reasonable load material handling conveyors with or without having attachment links. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and bigger have ?¡ãHeavy?¡À series hyperlink plates (i.e. hyperlink plates with the up coming larger chain size. The chain number is uncovered by including 2000 for the ASME/ANSI chain variety along with 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 huge rollers in order that the chain rolls on a conveyor track decreasing friction. Chain numbers are observed during the same way as mentioned above except the last digit within the chain variety is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the substantial roller.
Sprockets
Normally sprockets need to be developed specially for these chains according on the ASME/ANSI B29.three and B29.4 specifications nevertheless, for Transmission Series and Conveyor Series with Common (smaller) Rollers, ASME/ANSI B29.one Conventional roller chain sprockets may be utilised offered the number of teeth is 30 or additional.
