ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are created in accordance together with the ASME/ANSI B29.3 (Transmission Series) and B29.4 (Conveyor Series) American roller chain requirements. Normally these chains are equivalent to ASME/ANSI regular merchandise except that the pitch is double. They are really offered in Transmission Series, Conveyor Series with Common (tiny) Rollers and Conveyor Series with Substantial (oversized) Rollers.
Transmission Series
This series is usually employed on drives with slow to reasonable speeds, very low chain loads and extended center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by incorporating 2000 for the ASME/ANSI chain variety and also the prefi x letter ?¡ãA?¡À. Note that some organizations do not use a prefi x letter for this series so the chains could be represented as A2040, A2050 etc. or 2040, 2050 etc.
Conveyor Series with Typical (modest) Rollers
This series is often employed on light to reasonable load materials handling conveyors with or with no attachment back links. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and larger have ?¡ãHeavy?¡À series link plates (i.e. link plates on the upcoming larger chain size. The chain quantity is discovered by incorporating 2000 to the ASME/ANSI chain amount as well as prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À kind side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Significant (oversized) Rollers
These chains possess massive rollers in order that the chain rolls on the conveyor track minimizing friction. Chain numbers are observed while in the identical way as mentioned above except that the last digit to the chain amount is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the massive roller.
In general sprockets needs to be created specially for these chains in accordance on the ASME/ANSI B29.three and B29.4 requirements on the other hand, for Transmission Series and Conveyor Series with Conventional (small) Rollers, ASME/ANSI Typical roller chain sprockets may possibly be utilized presented the number of teeth is 30 or additional.
