Double Pitch roller chains are created in accordance together with the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain standards. Normally these chains are comparable to ASME/ANSI regular products except the pitch is double. They may be out there in Transmission Series, Conveyor Series with Regular (smaller) Rollers and Conveyor Series with Significant (oversized) Rollers.
Transmission Series
This series is usually used on drives with slow to moderate speeds, reduced chain loads and prolonged center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain number is obtained by adding 2000 to the ASME/ANSI chain amount as well as prefi x letter ?¡ãA?¡À. Note that some businesses will not use a prefi x letter for this series so the chains may be represented as A2040, A2050 and so forth. or 2040, 2050 and so forth.
Conveyor Series with Normal (modest) Rollers
This series is usually utilised on light to reasonable load material handling conveyors with or without having attachment back links. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and larger have ?¡ãHeavy?¡À series hyperlink plates (i.e. hyperlink plates on the up coming more substantial chain size. The chain number is observed by including 2000 for the ASME/ANSI chain variety as well as the prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À form side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Significant (oversized) Rollers
These chains possess huge rollers in order that the chain rolls on a conveyor track reducing friction. Chain numbers are located in the same way as mentioned above except the last digit within the chain variety is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the massive roller.
Sprockets
Normally sprockets really should be developed specially for these chains according on the ASME/ANSI B29.3 and B29.four specifications however, for Transmission Series and Conveyor Series with Normal (smaller) Rollers, ASME/ANSI B29.1 Conventional roller chain sprockets may be utilised supplied the quantity of teeth is 30 or far more.
