一、脱落蜗杆机构的功能C630车床溜板箱脱落蜗杆机构是起超载保护作用的。由进给箱传递来的运动,经光杆、换向齿轮、万向联轴节(如图1),再通过装在脱落蜗杆轴上的离合器6,带动空套在该轴上的六头蜗杆7。整个脱落蜗杆部分在杠杆4与长板2的作用下,绕支点上下转动。当蜗杆与蜗轮啮合时,实现刀具的纵横进给运动,离合器的啮合是依靠其螺旋面在弹簧预紧力的作用下实现的。如图1a所示。当外界的负载超过螺旋面离合器所预定允许负载时,离合器6通过螺旋面的作用克服弹簧5的预紧力,
First, the function of the worm off C630 lathe slide box off the worm mechanism is the role of overloading protection. By the feed box to the movement, the polished rod, reversing gear, universal coupling (Figure 1), and then through the worm on the off-axis clutch 6, driven by the empty set of six-axis worm on the shaft 7. The entire part of the worm off in the lever 4 and the role of long board 2, around the fulcrum up and down rotation. When the worm and worm gear meshing, the tool to achieve vertical and horizontal feed movement, the clutch meshing is to rely on the helical surface in spring preload to achieve. As shown in Figure 1a. When the external load exceeds the allowable load of the helical clutch, the clutch 6 overcomes the preload of the spring 5 through the helical surface,
