Double Pitch roller chains are generated in accordance with the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain standards. Generally these chains are similar to ASME/ANSI typical items except the pitch is double. They can be offered in Transmission Series, Conveyor Series with Normal (modest) Rollers and Conveyor Series with Massive (oversized) Rollers.
Transmission Series
This series is usually employed on drives with slow to moderate speeds, lower chain loads and extended center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by incorporating 2000 for the ASME/ANSI chain number and the prefi x letter ?¡ãA?¡À. Note that some corporations usually do not use a prefi x letter for this series so the chains may perhaps be represented as A2040, A2050 and so forth. or 2040, 2050 and so on.
Conveyor Series with Typical (compact) Rollers
This series is usually utilised on light to moderate load material managing conveyors with or without attachment hyperlinks. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and bigger have ?¡ãHeavy?¡À series website link plates (i.e. link plates on the upcoming greater chain dimension. The chain amount is uncovered by incorporating 2000 towards the ASME/ANSI chain variety and the prefi x letter ?¡ãC?¡À. Chains with the ?¡ãheavy?¡À kind side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Huge (oversized) Rollers
These chains possess substantial rollers in order that the chain rolls on a conveyor track reducing friction. Chain numbers are identified from the identical way as noted above except the last digit within the chain amount is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the significant roller.
Sprockets
Usually sprockets need to be generated specially for these chains in accordance on the ASME/ANSI B29.three and B29.four standards on the other hand, for Transmission Series and Conveyor Series with Common (smaller) Rollers, ASME/ANSI B29.one Conventional roller chain sprockets may well be utilized presented the amount of teeth is 30 or more.
