Double Pitch roller chains are made in accordance with all the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain specifications. Generally these chains are related to ASME/ANSI standard items except the pitch is double. These are obtainable in Transmission Series, Conveyor Series with Standard (little) Rollers and Conveyor Series with Big (oversized) Rollers.
Transmission Series
This series is often employed on drives with slow to moderate 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 to the ASME/ANSI chain quantity and also the prefi x letter ?¡ãA?¡À. Note that some companies tend not to use a prefi x letter for this series so the chains may perhaps be represented as A2040, A2050 and so forth. or 2040, 2050 and so on.
Conveyor Series with Standard (little) Rollers
This series is usually used on light to moderate load material managing conveyors with or without attachment hyperlinks. 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. website link plates with the subsequent more substantial chain size. The chain number is found by including 2000 to the ASME/ANSI chain quantity and also 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 Significant (oversized) Rollers
These chains possess huge rollers to ensure the chain rolls on the conveyor track lowering friction. Chain numbers are observed in the identical way as mentioned over except the last digit on the chain amount is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the huge roller.
Sprockets
On the whole sprockets need to be produced specially for these chains in accordance for the ASME/ANSI B29.three and B29.four requirements on the other hand, for Transmission Series and Conveyor Series with Standard (little) Rollers, ASME/ANSI B29.1 Conventional roller chain sprockets might be utilized offered the amount of teeth is thirty or a lot more.
