摘要

With the knowledge of the advantageous characteristics of the cylindrical worm gear drives having arched profile in axial section and the conical worm gear drives having linear profile in axial section, a new geometric type spiroid worm gear drive has been designed and then manufactured, and that is the spiroid worm gear drive having arched profile in axial section [2, 7]. We have developed the production technology of this new gear drive using classical machine. During the classical manufacturing process of conical thread surfaces with lathe center displacement, the worm shaft is driven with the help of the driving pin through the lathe fork. As a result of the shifting of the worm shaft by half cone angle, the path curve of the driving pin will be an ellipse path instead of a circle on the perpendicular plane to axis. The peripheral speed of the spindle is constant, but due to the ellipse path, the radius is constantly changing as a function of time. That is why the angular velocity and the rotation angle are also changing, and these cause pitch fluctuation during the manufacturing process of spiroid worms. During the manufacturing process, we have examined pitch errors which are caused by angular velocity fluctuation. In favour of angular velocity fluctuation, we have to ensure equal thread pitch during the manufacturing process of spiroid worms. That is why we have to design the geometrical shaping of the driving pin to solve the thread pitch fluctuation problem.
