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 specifications. Usually these chains are comparable to ASME/ANSI standard products except the pitch is double. They may be out there in Transmission Series, Conveyor Series with Common (modest) Rollers and Conveyor Series with Big (oversized) Rollers.
Transmission Series
This series is usually employed on drives with slow to moderate speeds, low chain loads and lengthy center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain number is obtained by adding 2000 to your ASME/ANSI chain variety as well as the prefi x letter ?¡ãA?¡À. Note that some firms will not use a prefi x letter for this series so the chains could be represented as A2040, A2050 and so forth. or 2040, 2050 and so on.
Conveyor Series with Typical (small) Rollers
This series is often used on light to moderate load materials dealing with conveyors with or with out 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 website link plates (i.e. hyperlink plates of your subsequent larger chain dimension. The chain amount is uncovered by adding 2000 to your ASME/ANSI chain quantity plus the prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À variety side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Significant (oversized) Rollers
These chains possess large rollers to ensure the chain rolls on a conveyor track decreasing friction. Chain numbers are identified inside the identical way as noted above except that the final digit around the chain variety is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the huge roller.
Sprockets
Normally sprockets ought to be developed specially for these chains according to your ASME/ANSI B29.three and B29.four standards on the other hand, for Transmission Series and Conveyor Series with Normal (little) Rollers, ASME/ANSI B29.one Typical roller chain sprockets could be employed provided the quantity of teeth is 30 or extra.
