ASME/ANSI Transmission Series Double Pitch Roller Chain

Double Pitch roller chains are created in accordance using the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain standards. Usually these chains are related to ASME/ANSI standard goods except the pitch is double. They are really offered in Transmission Series, Conveyor Series with Common (little) Rollers and Conveyor Series with Huge (oversized) Rollers.
Transmission Series
This series is usually used on drives with slow to reasonable speeds, low chain loads and extended center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain number is obtained by incorporating 2000 to your ASME/ANSI chain variety and the prefi x letter ?¡ãA?¡À. Note that some companies usually do not use a prefi x letter for this series so the chains might be represented as A2040, A2050 and so on. or 2040, 2050 and so on.
Conveyor Series with Normal (modest) Rollers
This series is usually made use of on light to moderate load material 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 greater have ?¡ãHeavy?¡À series link plates (i.e. link plates with the upcoming greater chain size. The chain number is discovered by adding 2000 towards the ASME/ANSI chain variety plus the prefi x letter ?¡ãC?¡À. Chains together with the ?¡ãheavy?¡À variety side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Large (oversized) Rollers
These chains possess substantial rollers so that the chain rolls on a conveyor track reducing friction. Chain numbers are found while in the same way as mentioned above except that the last digit within the chain quantity is changed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the huge roller.
Sprockets
Normally sprockets ought to be created specially for these chains in accordance on the ASME/ANSI B29.3 and B29.four specifications nevertheless, for Transmission Series and Conveyor Series with Typical (small) Rollers, ASME/ANSI B29.one Conventional roller chain sprockets could be utilized provided the number of teeth is 30 or a lot more.
