FAQ
  • What is a strain wave gear box?

    +

    A strain wave gear box is a type of gear system that produces high reduction ratios in a compact size. It uses the mechanics of a flexible element deforming to transmit motion and achieve high precision and torque.

  • How does a harmonic gear box work?

    +

    A harmonic gear box works by using a circular spline, flexspline, and a wave generator. The wave generator deforms the flexspline into an elliptical shape, which then engages with the teeth of the circular spline at two points, providing a high reduction ratio through the difference in tooth count between the engaged elements.

  • What are the main components of a strain wave drive?

    +

    The main components are the circular spline (fixed outer ring), the flexspline (flexible inner ring with fewer teeth), and the wave generator (an elliptical disc that fits inside the flexspline).

  • What are the advantages of using harmonic/strain wave gear boxes?

    +

    Strain wave/harmonic gearboxes offer high precision, zero backlashes, high torque capacity, compact size, and lightweight. They are also known for their excellent positional accuracy and repeatability.

  • What applications are harmonic-type drives used in?

    +

    They are used in applications requiring high precision and reliability, such as robotics, aerospace, defense, medical equipment, and semiconductor manufacturing equipment.

  • How do you select a strain wave drive for a specific application?

    +

    Selection depends on factors like torque requirements, desired reduction ratio, space constraints, load capacity, and environmental conditions. It's essential to consult with manufacturers or experts to choose the appropriate model.

  • What are the different types of Strain Wave Gearboxes?

    +

    Circular Spline Gearboxes

    Cup-Type Gearboxes

    Flat Gearboxes

  • What is a Circular Spline?

    +

    The Circular Spline in Strain Wave Gearboxes are characterized by their robust design.
