Double Pitch roller chains are generated in accordance together with the ASME/ANSI B29.3 (Transmission Series) and B29.4 (Conveyor Series) American roller chain standards. Usually these chains are related to ASME/ANSI typical merchandise except the pitch is double. They can be readily available in Transmission Series, Conveyor Series with Conventional (little) Rollers and Conveyor Series with Substantial (oversized) Rollers.
Transmission Series
This series is usually made use of 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 amount is obtained by adding 2000 towards the ASME/ANSI chain variety plus the prefi x letter ?¡ãA?¡À. Note that some companies never use a prefi x letter for this series so the chains may well be represented as A2040, A2050 and so forth. or 2040, 2050 etc.
Conveyor Series with Conventional (compact) Rollers
This series is usually utilised on light to moderate load material 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 greater have ?¡ãHeavy?¡À series website link plates (i.e. link plates of your upcoming greater chain size. The chain number is identified by adding 2000 towards the ASME/ANSI chain quantity as well as the prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À style side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Significant (oversized) Rollers
These chains possess huge rollers to ensure that the chain rolls on the conveyor track reducing friction. Chain numbers are located within the identical way as noted above except the final digit about the chain number is changed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the large roller.
Sprockets
In general sprockets ought to be generated specially for these chains in accordance to your ASME/ANSI B29.3 and B29.4 specifications however, for Transmission Series and Conveyor Series with Standard (small) Rollers, ASME/ANSI B29.one Normal roller chain sprockets may be utilised supplied the number of teeth is 30 or a lot more.
