Double Pitch roller chains are made in accordance together with the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain specifications. Usually these chains are similar to ASME/ANSI normal goods except the pitch is double. They are really available in Transmission Series, Conveyor Series with Normal (small) Rollers and Conveyor Series with Substantial (oversized) Rollers.
Transmission Series
This series is usually utilised 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 amount is obtained by including 2000 for the ASME/ANSI chain amount along with the prefi x letter ?¡ãA?¡À. Note that some organizations don’t use a prefi x letter for this series so the chains could be represented as A2040, A2050 and so forth. or 2040, 2050 and so on.
Conveyor Series with Regular (tiny) Rollers
This series is usually utilised on light to moderate load materials dealing with conveyors with or without attachment back links. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and bigger have ?¡ãHeavy?¡À series website link plates (i.e. website link plates on the following more substantial chain dimension. The chain amount is identified by adding 2000 on the ASME/ANSI chain number and also the prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À kind side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Massive (oversized) Rollers
These chains possess big rollers to ensure that the chain rolls on the conveyor track minimizing friction. Chain numbers are located inside the similar way as mentioned above except the last digit around the chain number is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the huge roller.
Sprockets
On the whole sprockets should be produced specially for these chains according for the ASME/ANSI B29.3 and B29.four standards even so, for Transmission Series and Conveyor Series with Standard (tiny) Rollers, ASME/ANSI B29.1 Standard roller chain sprockets may well be made use of presented the quantity of teeth is thirty or additional.
