DEFORMATION ANALYSIS OF FLEXIBLE WHEEL IN THE HARMONIC DRIVE.

The harmonic gearing unquestionably include among a prospective technology. It is about spur gearing where the meshing is achieved by the flexible deformation of one of the wheels. As a result of this deformation the shape of the flexible wheel changes from its original state resulting in incorrect meshing with the teeth of the opposite profile wheel. The deformation of the shape of the flexible wheel is the result of collision and interference, as well as the contact rate, occurring during the meshing of the flexible wheel with the rigid one. This transfer reaches some excellent properties such as great transference number in one stage, a sufficiently large effectiveness of a great kinematic accuracy and wide application. The disadvantage of a harmonic gear is that they are be sensitive to the torsion oscillations, design complexity and reduced service life of the elastic wheel. [ABSTRACT FROM AUTHOR]
