Double Pitch roller chains are produced in accordance together with the ASME/ANSI B29.three (Transmission Series) and B29.4 (Conveyor Series) American roller chain standards. On the whole these chains are similar to ASME/ANSI normal merchandise except the pitch is double. These are readily available in Transmission Series, Conveyor Series with Standard (modest) Rollers and Conveyor Series with Massive (oversized) Rollers.
Transmission Series
This series is usually made use of on drives with slow to reasonable speeds, reduced chain loads and extended center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by incorporating 2000 on the ASME/ANSI chain quantity and the prefi x letter ?¡ãA?¡À. Note that some businesses don’t use a prefi x letter for this series so the chains might be represented as A2040, A2050 and so on. or 2040, 2050 etc.
Conveyor Series with Conventional (small) Rollers
This series is usually made use of on light to reasonable load material handling conveyors with or with out attachment links. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and more substantial have ?¡ãHeavy?¡À series website link plates (i.e. hyperlink plates of the next greater chain size. The chain number is identified by incorporating 2000 to the ASME/ANSI chain quantity and the prefi x letter ?¡ãC?¡À. Chains together with the ?¡ãheavy?¡À sort side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Substantial (oversized) Rollers
These chains possess substantial rollers to ensure that the chain rolls on the conveyor track decreasing friction. Chain numbers are found in the identical way as noted above except that the final digit within the chain variety is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the substantial roller.
On the whole sprockets must be generated specially for these chains according for the ASME/ANSI B29.three and B29.four specifications nevertheless, for Transmission Series and Conveyor Series with Standard (smaller) Rollers, ASME/ANSI B29.one Normal roller chain sprockets may well be made use of provided the quantity of teeth is 30 or far more.
