Servo Zero Backlash Gearsets

Many Cone Drive products are available with Absolute Zero Backlash gearsets ideal for applications in which extremely accurate positioning is required.

Zero Backlash Servo gearsets

Absolute zero backlash worm gearsets have a two-piece worm, quilled together at the axial center of the worm thread. One segment of the worm is fixed in its bearing set, while the other segment is positioned laterally by adjustable-force pre-load disks, maintaining a consistent clamping force on both sides of the gear thus removing all backlash.

In this self-adjusting design, half of the power input worm contacts the drive side of the gear while the other half of the worm makes continuous contact with the opposing side of the gear. The result of this design innovation is absolute zero backlash, ideal for applications in which extremely accurate positioning is required. No-load chatter and free-travel shock in reversing applications are eliminated by the pre-loading characteristics of this design.
