Double Pitch roller chains are generated in accordance together with the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain standards. Usually these chains are similar to ASME/ANSI regular goods except that the pitch is double. These are available in Transmission Series, Conveyor Series with Regular (little) Rollers and Conveyor Series with Huge (oversized) Rollers.
Transmission Series
This series is usually applied on drives with slow to moderate speeds, reduced chain loads and long center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain amount is obtained by including 2000 for the ASME/ANSI chain number as well as prefi x letter ?¡ãA?¡À. Note that some providers never use a prefi x letter for this series so the chains may be represented as A2040, A2050 and so forth. or 2040, 2050 and so forth.
Conveyor Series with Standard (tiny) Rollers
This series is usually made use of on light to moderate load materials handling conveyors with or without the need of attachment hyperlinks. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and bigger have ?¡ãHeavy?¡À series hyperlink plates (i.e. link plates of your subsequent larger chain dimension. The chain number is identified by adding 2000 to the ASME/ANSI chain variety plus the prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À sort side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Substantial (oversized) Rollers
These chains possess big rollers in order that the chain rolls on a conveyor track minimizing friction. Chain numbers are found within the same way as noted over except that the last digit about the chain quantity is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the massive roller.
Sprockets
Normally sprockets really should be produced specially for these chains according for the ASME/ANSI B29.three and B29.four standards on the other hand, for Transmission Series and Conveyor Series with Normal (smaller) Rollers, ASME/ANSI B29.1 Normal roller chain sprockets may well be made use of presented the amount of teeth is 30 or much more.
