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 specifications. Usually these chains are similar to ASME/ANSI conventional products except the pitch is double. These are out there in Transmission Series, Conveyor Series with Conventional (small) Rollers and Conveyor Series with Massive (oversized) Rollers.
Transmission Series
This series is usually used on drives with slow to moderate speeds, lower chain loads and prolonged center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by adding 2000 on the ASME/ANSI chain amount plus the prefi x letter ?¡ãA?¡À. Note that some corporations will not use a prefi x letter for this series so the chains could be represented as A2040, A2050 and so on. or 2040, 2050 and so forth.
Conveyor Series with Standard (modest) Rollers
This series is usually made use of on light to reasonable load materials dealing with conveyors with or without attachment backlinks. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and larger have ?¡ãHeavy?¡À series website link plates (i.e. hyperlink plates of the upcoming greater chain dimension. The chain number is observed by incorporating 2000 for the ASME/ANSI chain amount and the prefi x letter ?¡ãC?¡À. Chains with 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 a conveyor track minimizing friction. Chain numbers are found from the very same way as mentioned over except the last digit on the chain number is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the big roller.
Sprockets
Normally sprockets need to be generated specially for these chains according towards the ASME/ANSI B29.3 and B29.four requirements however, for Transmission Series and Conveyor Series with Normal (small) Rollers, ASME/ANSI B29.1 Common roller chain sprockets may well be utilised provided the number of teeth is 30 or extra.
