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 requirements. Normally these chains are related to ASME/ANSI regular merchandise except that the pitch is double. These are available in Transmission Series, Conveyor Series with Common (small) Rollers and Conveyor Series with Big (oversized) Rollers.
Transmission Series
This series is often utilised on drives with slow to moderate speeds, lower chain loads and lengthy center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain amount is obtained by including 2000 to your 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 may well be represented as A2040, A2050 etc. or 2040, 2050 etc.
Conveyor Series with Typical (smaller) Rollers
This series is often utilised on light to reasonable load material managing conveyors with or without having attachment hyperlinks. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and bigger have ?¡ãHeavy?¡À series hyperlink plates (i.e. link plates from the up coming greater chain size. The chain number is located by including 2000 towards the ASME/ANSI chain number plus the prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À style side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Substantial (oversized) Rollers
These chains possess huge rollers to ensure that the chain rolls on the conveyor track lowering friction. Chain numbers are discovered while in the very same way as noted above except that the last digit to the chain variety is changed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the massive roller.
Sprockets
In general sprockets must be produced specially for these chains according on the ASME/ANSI B29.3 and B29.4 standards even so, for Transmission Series and Conveyor Series with Common (compact) Rollers, ASME/ANSI B29.one Conventional roller chain sprockets may be made use of provided the amount of teeth is 30 or extra.
