Double Pitch roller chains are produced in accordance with all the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain requirements. Usually these chains are comparable to ASME/ANSI standard merchandise except that the pitch is double. They may be out there in Transmission Series, Conveyor Series with Normal (modest) Rollers and Conveyor Series with Substantial (oversized) Rollers.
Transmission Series
This series is usually employed on drives with slow to reasonable 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 on 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 perhaps be represented as A2040, A2050 and so on. or 2040, 2050 and so on.
Conveyor Series with Normal (compact) Rollers
This series is usually 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 greater have ?¡ãHeavy?¡À series website link plates (i.e. website link plates of the up coming bigger chain size. The chain number is observed 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 lowering friction. Chain numbers are observed in the identical way as mentioned over except the final digit about the chain variety is modified from ?¡ã0?¡À to ?¡ã2?¡À which denotes the large roller.
Sprockets
In general 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 Conventional roller chain sprockets may be employed presented the number of teeth is thirty or a lot more.
