Double Pitch roller chains are developed in accordance with the ASME/ANSI B29.three (Transmission Series) and B29.four (Conveyor Series) American roller chain requirements. In general these chains are comparable to ASME/ANSI common goods except that the pitch is double. They’re offered in Transmission Series, Conveyor Series with Normal (compact) Rollers and Conveyor Series with Massive (oversized) Rollers.
Transmission Series
This series is usually made use of 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 variety is obtained by incorporating 2000 to the ASME/ANSI chain quantity and the prefi x letter ?¡ãA?¡À. Note that some corporations never use a prefi x letter for this series so the chains may possibly be represented as A2040, A2050 and so forth. or 2040, 2050 etc.
Conveyor Series with Regular (small) Rollers
This series is usually utilised on light to reasonable load materials dealing with conveyors with or without having attachment links. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and more substantial have ?¡ãHeavy?¡À series hyperlink plates (i.e. link plates on the up coming greater chain size. The chain variety is located by adding 2000 on the ASME/ANSI chain amount as well as the prefi x letter ?¡ãC?¡À. Chains together with the ?¡ãheavy?¡À form side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Massive (oversized) Rollers
These chains possess substantial rollers to ensure the chain rolls on the conveyor track minimizing friction. Chain numbers are identified in the very same way as noted above except the last digit about the chain quantity is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the significant roller.
On the whole sprockets must be made specially for these chains in accordance on the ASME/ANSI B29.3 and B29.four standards nevertheless, for Transmission Series and Conveyor Series with Standard (tiny) Rollers, ASME/ANSI B29.1 Typical roller chain sprockets may be utilized supplied the amount of teeth is 30 or more.
