The internal tooth 421 being meshed with flexbile gear 1 is provided with, the inner ring for making the roller intersect bearing 4 forms traditional firm wheel, and then
Traditional firm wheel, effective reduces cost and mitigation weight are saved, overall volume is also accordingly reduced, reduce installation occupancy empty
Between, beneficial to the lightweight and miniaturization of equipment.
Preferably, the outer ring 41 that the roller intersects bearing 4 is fixed on flexbile gear 1 by screw 5, it is easy to install, and dress
With tight, connective stability is good.
For convenience of installing, flange hole is provided with the elliptic cam 3.Intersect the outer of bearing 4 in the flexbile gear 1 and roller
Circle is provided with flange hole.
The announcement and teaching of book according to the above description, the utility model those skilled in the art can also be to above-mentioned reality
The mode of applying is changed and changed.Therefore, the utility model is not limited to specific embodiment disclosed and described above, right
