On the wheel side the picture mirrors the shaft. Different modules on the two flanks produce different addendum modification coefficients and different rolling-circle diameters, so the front and rear tooth profiles of the wheel are not identical, even though the tooth thickness and tooth gap stay constant around the wheel’s circumference. The outcome is a drive that delivers single-digit-micrometre backlash when needed, and holds it through reversing service that would quickly wear out a conventional worm set. Korean machine-tool builders, rotary-indexing specialists and stamping-press manufacturers are the most frequent buyers.<\/p>\n<\/section>\n

The values below reflect the standard catalogue envelope for duplex sets. All geometry is cut to customer drawing \u2014 duplex worms are almost never stock items because the lead-difference value itself is an application-specific parameter. Values marked “typical range” reflect industry-standard practice where the customer has not yet specified a tighter target.<\/p>\n

\u25b6<\/span> Both the shaft and the wheel are stamped with a small arrow at the manufacturer’s assembly mark. When fitting the pair into the housing, rotate the wheel until the arrow faces the front, then feed the shaft into engagement so that its arrow points the same direction. If the arrows point opposite, the thicker tooth is meeting the thinner tooth of the wheel and the drive will bind before it reaches the design centre distance.<\/p>\n

\u25b6<\/span> The tip of the duplex shaft carries a 60-degree V-groove cut 0.3 mm deep \u2014 this is the reference tooth. When the reference tooth sits exactly aligned with the rotational centre of the wheel and the centre distance is set to the drawing value “a”, the backlash sits at the design target (typically \u00b1 0.045 mm for our catalogue frames). From that starting point, axial shift is used to tune backlash up or down as the application demands.<\/p>\n
