Double Pitch roller chains are developed in accordance together with the ASME/ANSI B29.three (Transmission Series) and B29.4 (Conveyor Series) American roller chain specifications. On the whole these chains are related to ASME/ANSI common solutions except the pitch is double. They are available in Transmission Series, Conveyor Series with Typical (modest) Rollers and Conveyor Series with Significant (oversized) Rollers.
Transmission Series
This series is usually utilised on drives with slow to reasonable speeds, low chain loads and extended center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by including 2000 to your ASME/ANSI chain number as well as the prefi x letter ?¡ãA?¡À. Note that some providers don’t use a prefi x letter for this series so the chains may perhaps be represented as A2040, A2050 and so on. or 2040, 2050 and so forth.
Conveyor Series with Conventional (smaller) Rollers
This series is usually utilised on light to reasonable load materials handling conveyors with or without the need of attachment 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. website link plates with the next larger chain size. The chain variety is identified by adding 2000 towards the ASME/ANSI chain variety and the prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À variety side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Huge (oversized) Rollers
These chains possess large rollers to ensure the chain rolls on the conveyor track cutting down friction. Chain numbers are found from the identical way as mentioned above except the final digit over the chain variety is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the substantial roller.
Generally sprockets need to be made specially for these chains according to the ASME/ANSI B29.three and B29.4 standards having said that, for Transmission Series and Conveyor Series with Standard (tiny) Rollers, ASME/ANSI B29.1 Standard roller chain sprockets may well be employed provided the amount of teeth is thirty or extra.
