Double Pitch roller chains are produced in accordance with the ASME/ANSI B29.3 (Transmission Series) and B29.4 (Conveyor Series) American roller chain specifications. In general these chains are related to ASME/ANSI typical merchandise except the pitch is double. They are really accessible in Transmission Series, Conveyor Series with Typical (smaller) Rollers and Conveyor Series with Significant (oversized) Rollers.
Transmission Series
This series is often made use of on drives with slow to reasonable speeds, very low chain loads and long center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain variety is obtained by incorporating 2000 on the ASME/ANSI chain quantity as well as 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 possibly be represented as A2040, A2050 etc. or 2040, 2050 etc.
Conveyor Series with Regular (smaller) Rollers
This series is often used on light to moderate load material dealing with conveyors with or with out attachment back links. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and more substantial have ?¡ãHeavy?¡À series hyperlink plates (i.e. link plates from the following bigger chain size. The chain amount is observed by adding 2000 for the ASME/ANSI chain number as well as prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À style side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Significant (oversized) Rollers
These chains possess huge rollers so that the chain rolls on a conveyor track reducing friction. Chain numbers are discovered from the exact same way as noted above except the final digit on the chain quantity is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the substantial roller.
Sprockets
On the whole sprockets need to be created specially for these chains in accordance to your ASME/ANSI B29.three and B29.four requirements nevertheless, for Transmission Series and Conveyor Series with Conventional (compact) Rollers, ASME/ANSI B29.one Conventional roller chain sprockets may be used presented the amount of teeth is thirty or additional.
