Characteristics of high precision worm gear reducer

High precision worm gear reducer is an ideal substitute for a precision planetary gearbox, the equipment manufacturers can substantially decrease the cost of a precision planetary gearbox.SDT Transmission high precision worm gear reducer’s backlash down to 1 arc minute, its structure features advantages are as follows:

  • Hollow output with shrink disc, high precision, for easy integration.
  • Output bore with keyway, convenient installation, easy to integrate.
  • Solid shaft output (single. double), high stiffness, traditional solution.
  • Gear reducer connects with the servo motor 90-degree installation, saving more space.
