HarmonicDrive® Speed Reducer for Precision Control Speed Reducer FB Series Component Type

Features

  • Flat, planar structure
  • Flexible customizing possible
  • Backlash-free

The FB series is engineered with a flat type, compact structure.
Its versatile customizing features allow for space-saving designs.

FB Series Component Type Structure

Circular spline D It has the same number of teeth as the flexspline. As it does not generate relative rotation with the flexspline, it rotates at the same speed as the flexspline. Circular spline S it has two more teeth than the flexspline, like the cup-type circular spline. Wave generator Flexspline How to tell circular spline D from circular spline S the peripheral chamfering of circular spline D is larger than that of circular spline S.
