Claim 1:
2. The nutation reducer as claimed in claim 1, wherein said nutation generating mechanism comprises:
a tilted disc rotationally provided in said case on said output shaft, wherein two opposite sides of the tilted disc form a pair of symmetrically tilted planes, and said tilted disc is driven by an actuating mechanism; and
planar high-density ball bearings, wherein the planar high-density ball bearing is interposed between the tilted disc and the nutation gear of the nutation gear pairs, and both sides of the tilted disc and the back side of each nutation gear in said gear pairs serve as raceways of said planar high-density ball bearing;
wherein two nutation gears in two said nutation gear pairs have the same number of teeth, and the two non-nutation gears in two said nutation gear pairs have the same number of teeth, and
when said tilted disc rotates, the tilted planes on both sides of the tilted disc drives the nutation gears to perform the nutation movement, making the teeth of the nutation gears roll on the teeth of the non-nutation gears.
