Double Pitch roller chains are produced in accordance using the ASME/ANSI B29.3 (Transmission Series) and B29.4 (Conveyor Series) American roller chain standards. On the whole these chains are comparable to ASME/ANSI typical merchandise except that the pitch is double. They’re offered in Transmission Series, Conveyor Series with Normal (little) Rollers and Conveyor Series with Huge (oversized) Rollers.
Transmission Series
This series is usually employed on drives with slow to moderate speeds, low chain loads and long center distances. Side plates possess a fi gure ?¡ã8?¡À contour. The chain variety is obtained by adding 2000 for the ASME/ANSI chain variety along with the prefi x letter ?¡ãA?¡À. Note that some companies usually do not use a prefi x letter for this series so the chains may possibly be represented as A2040, A2050 and so on. or 2040, 2050 etc.
Conveyor Series with Regular (modest) Rollers
This series is often made use of on light to reasonable load materials managing conveyors with or without the need of attachment links. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and bigger have ?¡ãHeavy?¡À series website link plates (i.e. website link plates of the up coming larger chain dimension. The chain number is located by incorporating 2000 to the ASME/ANSI chain quantity and the prefi x letter ?¡ãC?¡À. Chains with all the ?¡ãheavy?¡À variety side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Massive (oversized) Rollers
These chains possess massive rollers in order that the chain rolls on a conveyor track decreasing friction. Chain numbers are identified during the identical way as noted over except the final digit within the chain variety is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the large roller.
Sprockets
Usually sprockets really should be made specially for these chains in accordance on the ASME/ANSI B29.three and B29.four standards on the other hand, for Transmission Series and Conveyor Series with Typical (tiny) Rollers, ASME/ANSI B29.1 Typical roller chain sprockets may be employed offered the number of teeth is thirty or a lot more.
