Double Pitch roller chains are made in accordance with the ASME/ANSI B29.3 (Transmission Series) and B29.4 (Conveyor Series) American roller chain requirements. Generally these chains are similar to ASME/ANSI conventional solutions except that the pitch is double. They can be out there in Transmission Series, Conveyor Series with Normal (smaller) Rollers and Conveyor Series with Huge (oversized) Rollers.
Transmission Series
This series is usually utilized 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 quantity is obtained by including 2000 on the ASME/ANSI chain quantity plus the prefi x letter ?¡ãA?¡À. Note that some corporations will not use a prefi x letter for this series so the chains may perhaps be represented as A2040, A2050 etc. or 2040, 2050 etc.
Conveyor Series with Typical (smaller) Rollers
This series is usually employed on light to reasonable load materials managing conveyors with or without having attachment backlinks. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and larger have ?¡ãHeavy?¡À series website link plates (i.e. hyperlink plates in the up coming bigger chain dimension. The chain number is found by adding 2000 to your ASME/ANSI chain quantity and the prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À sort side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Huge (oversized) Rollers
These chains possess big rollers to ensure the chain rolls on a conveyor track cutting down friction. Chain numbers are located while in the exact same way as mentioned over except that the final digit over the chain amount is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the big roller.
In general sprockets must be generated specially for these chains according for the ASME/ANSI B29.3 and B29.4 standards nevertheless, for Transmission Series and Conveyor Series with Typical (modest) Rollers, ASME/ANSI B29.1 Normal roller chain sprockets may well be utilised provided the amount of teeth is thirty or more.
