RESEARCH ON THE MANUFACTURING AND EVALUATION METHOD FOR A CURVE-FACE GEAR

抄録

Curve-face gear is a new type transmission device combining the common transmission characteristics of non-circular gears and face gears, which can transfer the motion and power between the intersecting shaft and staggered shaft. Given the complexity of the tooth generation of curve-face gear, 1) some machining methods, including three axis NC machining method , five-axis CNC machining method and the combined processing method of additive manufacturing and five-axis CNC machining, were introduced. 2) Based on space gear meshing theory and the machining principle, the machining models of curve-face gear were established.
In order to verify the accuracy of the obtained gear, tooth surface measurement was applied, a new accuracy evaluation method for pitch deviations and tooth profile deviation of curve-face gear was processed. The results show that the tooth surface accuracy of the curve-face gear is high. The design of the curve-face gear, and its processing methods have been verified.
