Double Pitch roller chains are made in accordance together with the ASME/ANSI B29.three (Transmission Series) and B29.4 (Conveyor Series) American roller chain standards. Generally these chains are similar to ASME/ANSI common solutions except the pitch is double. They may be available in Transmission Series, Conveyor Series with Standard (modest) Rollers and Conveyor Series with Large (oversized) Rollers.
Transmission Series
This series is often employed on drives with slow to reasonable speeds, low chain loads and lengthy center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain variety is obtained by adding 2000 on the ASME/ANSI chain amount and also 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 etc. or 2040, 2050 and so on.
Conveyor Series with Standard (little) Rollers
This series is often employed on light to moderate load materials handling conveyors with or devoid of attachment backlinks. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and more substantial have ?¡ãHeavy?¡À series link plates (i.e. hyperlink plates with the up coming greater chain size. The chain number is located by incorporating 2000 towards the ASME/ANSI chain amount plus the prefi x letter ?¡ãC?¡À. Chains together with the ?¡ãheavy?¡À form side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Huge (oversized) Rollers
These chains possess massive rollers in order that the chain rolls on the conveyor track minimizing friction. Chain numbers are found within the exact same way as mentioned above except that the last digit about the chain amount is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the significant roller.
In general sprockets should be developed specially for these chains according for the ASME/ANSI B29.three and B29.4 requirements on the other hand, for Transmission Series and Conveyor Series with Typical (tiny) Rollers, ASME/ANSI B29.one Standard roller chain sprockets may be utilised presented the number of teeth is thirty or extra.
