ANALYSIS AND CALCULATION OF TOOTH PROFILE OF QUASI-ELLIPSOIDAL GEAR DRIVE IN A ROBOT FLEXIBLE JOINT

The manufacturing of gear teeth is greatly simplified by using a new conical surfaces of the teeth, Themeshing equations and surfaces equation of such concave teeth are derived. Its gcomctrcal characteristicsare analyzed, and also a calculation method is obtained. At last, the analysis and calculation of the overlap coefficient show that the quasi-ellipsoidal gear pairs can realize continuous transmissions.
