Double Pitch roller chains are produced in accordance with the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain standards. On the whole these chains are comparable to ASME/ANSI regular products except that the pitch is double. They’re available in Transmission Series, Conveyor Series with Normal (modest) Rollers and Conveyor Series with Big (oversized) Rollers.
Transmission Series
This series is often used on drives with slow to reasonable speeds, reduced chain loads and extended center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain number is obtained by incorporating 2000 to the ASME/ANSI chain variety as well as prefi x letter ?¡ãA?¡À. Note that some organizations don’t use a prefi x letter for this series so the chains might be represented as A2040, A2050 etc. or 2040, 2050 and so on.
Conveyor Series with Normal (smaller) Rollers
This series is often applied on light to reasonable load materials managing conveyors with or without attachment hyperlinks. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and more substantial have ?¡ãHeavy?¡À series website link plates (i.e. link plates of the following more substantial chain size. The chain amount is found by incorporating 2000 on the ASME/ANSI chain quantity along with the prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À sort side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Massive (oversized) Rollers
These chains possess big rollers so that the chain rolls on a conveyor track cutting down friction. Chain numbers are found in the identical way as noted over except that the final digit on the chain number is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the huge roller.
Sprockets
Normally sprockets really should be created specially for these chains according on the ASME/ANSI B29.three and B29.4 requirements nevertheless, for Transmission Series and Conveyor Series with Standard (modest) Rollers, ASME/ANSI B29.1 Conventional roller chain sprockets may possibly be utilized offered the number of teeth is 30 or additional.
