在滚齿工作中,刀杆托架锥轴承的调整,是滚齿机调整项目中一项技术要求较高、难度较大的工作。因为,调整间隙过大,则造成刀杆在工作负载下的翘曲,使滚刀的径向跳动增大,从而直接对齿轮的加工精度、齿部表面粗糙度产生不良影响。调整间隙过小,在机床运行过程中,则有可能出现“闷车”现象,造成轴承铜套烧坏咬死事故。然而,如何将刀杆托架锥轴承调整 In hobbing work, the adjustment of cutterhead bracket cone bearing is one of the technical requirements of hobbing machine adjustment project, which is more difficult. Because, to adjust the gap is too large, then cause the arbor in the work load warpage, hob radial runout increases, which directly on the gear machining accuracy, tooth surface roughness adversely affected. To adjust the gap is too small, in the process of machine tool operation, there may be “boring car” phenomenon, resulting in bearing bush burned to death. However, how to adjust the holder taper bearing
