Double Pitch roller chains are developed in accordance together with the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain requirements. 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 Conventional (small) Rollers and Conveyor Series with Large (oversized) Rollers.
Transmission Series
This series is often utilised on drives with slow to reasonable speeds, reduced chain loads and prolonged center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain number is obtained by incorporating 2000 towards the ASME/ANSI chain quantity plus the prefi x letter ?¡ãA?¡À. Note that some organizations usually do not use a prefi x letter for this series so the chains may well be represented as A2040, A2050 and so on. or 2040, 2050 etc.
Conveyor Series with Common (small) Rollers
This series is often utilised on light to reasonable load materials dealing with conveyors with or without the need of attachment backlinks. 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 up coming more substantial chain size. The chain variety is located by incorporating 2000 to your ASME/ANSI chain variety and the prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À variety side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Substantial (oversized) Rollers
These chains possess significant rollers so that the chain rolls on a conveyor track decreasing friction. Chain numbers are uncovered during the very same way as mentioned above except that the last digit about the chain amount is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the massive roller.
Sprockets
On the whole sprockets needs to be made specially for these chains in accordance to your ASME/ANSI B29.3 and B29.4 specifications even so, for Transmission Series and Conveyor Series with Common (tiny) Rollers, ASME/ANSI B29.one Normal roller chain sprockets may be used offered the amount of teeth is thirty or additional.
