A HARMONIC DRIVE APPARATUS |
摘要 |
<p>A harmonic drive apparatus includes a circular spline having a number of internal teeth, a radially flexible cylindrical flexspline having outer spline teeth engageable with the internal teeth of the circular spline, and a wave generator disposed within the flexspline in engagement therewith. The circular spline, the flexspline, and the wave generator are rotatable around a rotational axis. The number of the external spline teeth of the flexspline is less than the number of the internal spline teeth of the circular spline. The wave generator has a cam section which generates a circumferential wave of radial deflection of the flexspline for causing the external spline teeth thereof to locally engage with the internal spline teeth of the circular spline. The cam section has elasticity in its radial direction sufficient for biasing the flexspline against the circular spline to absorb any play between the flexspline and the circular spline.</p> |
