ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are developed in accordance together with the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain specifications. On the whole these chains are equivalent to ASME/ANSI common goods except that the pitch is double. They may be readily available in Transmission Series, Conveyor Series with Conventional (compact) Rollers and Conveyor Series with Substantial (oversized) Rollers.
Transmission Series
This series is often utilised on drives with slow to moderate speeds, low chain loads and extended center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain number is obtained by incorporating 2000 on the ASME/ANSI chain number and also the prefi x letter ?¡ãA?¡À. Note that some firms never use a prefi x letter for this series so the chains may possibly be represented as A2040, A2050 and so on. or 2040, 2050 and so forth.
Conveyor Series with Normal (little) Rollers
This series is usually utilised on light to reasonable load materials dealing with conveyors with or without attachment backlinks. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and more substantial have ?¡ãHeavy?¡À series link plates (i.e. link plates in the upcoming bigger chain size. The chain number is identified by incorporating 2000 to your ASME/ANSI chain quantity and also the prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À form side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Substantial (oversized) Rollers
These chains possess big rollers to ensure that the chain rolls on the conveyor track decreasing friction. Chain numbers are identified while in the exact same way as mentioned above except that the last digit around the chain amount is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the significant roller.
Sprockets
Normally sprockets really should be developed specially for these chains according to the ASME/ANSI B29.3 and B29.4 requirements on the other hand, for Transmission Series and Conveyor Series with Typical (tiny) Rollers, ASME/ANSI B29.1 Standard roller chain sprockets could be used provided the amount of teeth is 30 or extra.
