Double Pitch roller chains are generated in accordance together with the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain requirements. On the whole these chains are similar to ASME/ANSI typical items except the pitch is double. These are out there in Transmission Series, Conveyor Series with Typical (little) Rollers and Conveyor Series with Substantial (oversized) Rollers.
Transmission Series
This series is often used on drives with slow to reasonable speeds, lower chain loads and long center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain amount is obtained by adding 2000 towards the ASME/ANSI chain variety as well as prefi x letter ?¡ãA?¡À. Note that some firms usually do not use a prefi x letter for this series so the chains may perhaps be represented as A2040, A2050 etc. or 2040, 2050 and so on.
Conveyor Series with Conventional (tiny) Rollers
This series is usually utilised on light to reasonable load material managing conveyors with or without the need of attachment backlinks. 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. website link plates in the up coming bigger chain dimension. The chain amount is uncovered by including 2000 for the ASME/ANSI chain amount plus the prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À kind side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Massive (oversized) Rollers
These chains possess significant rollers to ensure that the chain rolls on the conveyor track lowering friction. Chain numbers are identified during the same way as noted above except that the final digit to the chain variety is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the substantial roller.
Sprockets
On the whole sprockets should be produced specially for these chains according to the ASME/ANSI B29.3 and B29.four requirements nonetheless, for Transmission Series and Conveyor Series with Conventional (small) Rollers, ASME/ANSI B29.1 Conventional roller chain sprockets may be utilized offered the quantity of teeth is 30 or extra.
