蜗杆的车削加工在机械制造领域中占有非常重要的位置。蜗杆常与蜗轮组合构成运动副应用在减速传动机构中,以传动两轴在空间成90°交错的运动。蜗杆的齿形与梯形蜗杆很相似,但蜗杆的齿形较大,在切削时很难把握,由于切削余量较大,并很容易在车削时产生振动使工件变形,如果刀具、切削用量选择不合理很容易出现扎刀现象,不能很好的提高生产质量和生产效率。
The turning of the worm occupies a very important place in the field of machine construction. The worm is often combined with a worm gear to form a kinematic pair, which is used in a decelerating transmission mechanism to drive the two shafts to make a 90 ° staggered movement in space. Worm teeth and trapezoidal worm is very similar, but the worm tooth shape is larger, difficult to grasp in the cutting, due to the larger cutting allowance, and it is easy to produce vibration during turning deformation of the workpiece, if the cutting tool, the amount of choice Irrational is very easy to appear Zhadao phenomenon, not good to improve production quality and production efficiency.
