ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are made in accordance together with the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain standards. Normally these chains are equivalent to ASME/ANSI normal items except that the pitch is double. They are accessible in Transmission Series, Conveyor Series with Typical (small) Rollers and Conveyor Series with Large (oversized) Rollers.
Transmission Series
This series is often employed on drives with slow to moderate speeds, reduced chain loads and prolonged center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain variety is obtained by including 2000 towards the ASME/ANSI chain quantity plus the prefi x letter ?¡ãA?¡À. Note that some businesses usually do not use a prefi x letter for this series so the chains may possibly be represented as A2040, A2050 and so forth. or 2040, 2050 etc.
Conveyor Series with Normal (little) Rollers
This series is usually utilised on light to reasonable load materials dealing with conveyors with or without attachment hyperlinks. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and larger have ?¡ãHeavy?¡À series website link plates (i.e. link plates in the subsequent greater chain dimension. The chain number is identified by incorporating 2000 to your ASME/ANSI chain amount as well as prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À variety side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Significant (oversized) Rollers
These chains possess substantial rollers to ensure the chain rolls on a conveyor track decreasing friction. Chain numbers are uncovered during the identical way as mentioned above except that the final digit about the chain amount is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the substantial roller.
Sprockets
Usually sprockets ought to be created specially for these chains in accordance to the ASME/ANSI B29.3 and B29.4 requirements on the other hand, for Transmission Series and Conveyor Series with Typical (modest) Rollers, ASME/ANSI B29.1 Normal roller chain sprockets might be made use of offered the amount of teeth is 30 or far more.
