Claim:
1. A harmonic drive featuring helix-facilitated lubrication, comprising: a circular spline; a flexspline, being positioned in the circular spline so as to mesh with the circular spline; a wave generator, having a bearing positioned in the flexspline, an elliptic wheel positioned in the bearing, and a shaft coupling connected to the elliptic wheel, so that a lubricant-holding space is defined between the wave generator and the flexspline; and an agitating member, being positioned in the lubricant-holding space and having a rotatory part and at least one blade part, wherein the rotatory part is connected to the shaft coupling of the wave generator, and the blade part is such provided on a peripheral surface of the rotatory part that the blade part extends in a helical pattern along an axial direction of the rotatory part.
