ميزات المنتج وتطبيقاته

Precision double lead worm gear (variable tooth thickness) features zero/low backlash, with adjustable clearance by axially moving the worm. Wear compensation ensures long-term high precision. Widely used in CNC rotary tables, 4th axis, robots, radar, medical equipment and other precision transmission applications.

Product Overview
Precision double lead worm gear (variable tooth thickness) is a high-precision transmission set with zero/low backlash. The worm has different leads on two flanks; moving the worm axially can accurately adjust backlash without changing center distance. It supports wear compensation and maintains long-term high precision.
2. Structure & Principle
  • Worm: Double-lead design, different left/right leads, linear tooth thickness change
  • Wheel: Tin bronze / aluminum bronze, matching variable tooth profile
  • Adjustment: Axial movement → backlash adjustable 0～0.01mm
  • Feature: Line contact, multi-tooth meshing, low vibration, low noise, high rigidity
3. Key Advantages
  • Zero/low backlash, angular backlash ≤1 arcmin
  • Wear compensation, service life extended 3–5 times
  • High positioning & indexing accuracy
  • High rigidity, low vibration, noise ≤55dB
  • Self-locking for anti-reverse safety
  • Compact structure, smaller size at same torque
4. Typical Applications
  • Precision machine tools: CNC rotary table, 4th axis, tool changer, grinder axis
  • Automation: Robot joint, precision positioning stage, vision inspection
  • Aerospace: Radar turntable, antenna drive, precision actuator
  • Medical: CT scanner, surgical robot, precision lifting table
5. Selection Guide
  • High precision / positioning / indexing → choose double lead
  • High-frequency forward/reverse / continuous running → double lead preferred
  • Select center distance by torque ×1.25 safety factor
  • Ratio 10.25–90, customizable up to 400
