ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are produced in accordance using the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain specifications. Generally these chains are similar to ASME/ANSI typical merchandise except that the pitch is double. These are readily available in Transmission Series, Conveyor Series with Conventional (smaller) Rollers and Conveyor Series with Huge (oversized) Rollers.
Transmission Series
This series is usually utilised on drives with slow to reasonable speeds, lower chain loads and long center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by incorporating 2000 to the ASME/ANSI chain number as well as the prefi x letter ?¡ãA?¡À. Note that some firms tend not to use a prefi x letter for this series so the chains could be represented as A2040, A2050 and so forth. or 2040, 2050 etc.
Conveyor Series with Standard (smaller) Rollers
This series is often employed on light to reasonable load material dealing with conveyors with or devoid of attachment backlinks. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and greater have ?¡ãHeavy?¡À series link plates (i.e. link plates on the upcoming larger chain dimension. The chain variety is located by adding 2000 towards the ASME/ANSI chain variety as well as the prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À sort side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Substantial (oversized) Rollers
These chains possess massive rollers to ensure the chain rolls on the conveyor track cutting down friction. Chain numbers are uncovered during the same way as noted over except the final digit on the chain amount is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the significant roller.
Sprockets
In general sprockets must be developed specially for these chains according towards the ASME/ANSI B29.3 and B29.four requirements even so, for Transmission Series and Conveyor Series with Common (smaller) Rollers, ASME/ANSI B29.1 Common roller chain sprockets may well be made use of offered the amount of teeth is thirty or far more.
