Every standard worm drive accumulates backlash as the tooth faces wear. The worn metal is gone \u2014 the center distance cannot be reduced, and the only way to close the gap between the worm thread flank and the wheel tooth face in a standard drive is to replace both the worm and the wheel. This is expensive and time-consuming, but for most industrial drives it is acceptable because the backlash specification is not critical. In precision positioning drives \u2014 CNC rotary tables, milling machine feed systems, measuring machine axes \u2014 even 0.05 mm of angular backlash is too much. A 0.05 mm backlash at the worm wheel pitch circle of a 100 mm diameter wheel translates to approximately 3.4 arc-minutes of positional error, enough to cause visible surface irregularities on a machined workpiece. Korea Ever-Power Worm Gear Co., Ltd manufactures duplex worm gear sets \u2014 also called dual-lead worm gears \u2014 that solve this problem by making the worm’s tooth thickness vary continuously along its length, so that axial shift of the worm restores the original backlash without replacing any components. This \u00e7iftli sonsuz di\u015fli<\/a> set is the correct solution wherever bidirectional positioning accuracy must be maintained over the drive’s service life.<\/p>\n

At the worm wheel, the different modules on each flank produce different addendum modification coefficients and different rolling circle diameters on the front side versus the rear side of each wheel tooth. Because of this asymmetry, the tooth profiles differ at the front and rear. However \u2014 and this is critical to understanding why duplex works \u2014 the thickness of each wheel tooth and the tooth gaps remain constant around the wheel circumference. This means the worm can shift to any axial position and the wheel tooth geometry is always correctly matched to the worm at that position. There is no “preferred” axial location with better contact than others \u2014 the contact quality is maintained uniformly across the full adjustment range.<\/p>\n

An arrow indicating the correct orientation of assembly is stamped on both the duplex worm and the worm wheel. When assembling, position the worm wheel so that its arrow mark faces toward the front (toward you). Orient the worm so that the direction of its arrow mark coincides with the direction of the wheel’s arrow mark \u2014 both arrows pointing the same way. Should the assembly be incorrect, the center distance “a” will become greater than the nominal design value, resulting in difficulty completing the assembly and, if forced, improper gear engagement that produces excessive noise, vibration, and accelerated tooth wear from the first revolution.<\/p>\n

A V-groove (60\u00b0, 0.3 mm deep) machined on the tip peripheral of one specific duplex worm tooth marks the reference tooth. This reference tooth is the tooth at the axial position that produces near-zero backlash (\u00b10.045 mm) when positioned in alignment with the center of rotation of the worm wheel, with the center distance set at the nominal design value “a.” The procedure for setting zero backlash is: (1) set the housing center distance to the nominal value “a”; (2) rotate the worm until the V-groove reference tooth is aligned with the wheel’s rotation axis; (3) lock the worm housing or bearing adjustment at this position. For applications requiring slightly positive backlash (to accommodate thermal expansion or to prevent tooth binding under load), shift the worm axially toward the thin end by the calculated amount before locking.<\/p>\n

Duplex worm gears are specified wherever backlash is unwanted or can be harmful: to maintain repeated high-precision positioning in both directions, to prevent impulse-loaded damage when contact flanks alternate, and in drives where positioning error accumulates over time. Typical applications include rotary and tilting tables, milling machines, and presses. The following examples provide the engineering context for each application’s specific backlash requirement.<\/p>\n
