81年5月我们在本刊发表了“摆线磨齿机精度的修复”一文,得到了不少读者的帮助和指教。为了更进一步解决 QC001摆线磨齿机的精度与使用寿命的问题,我们对一台老的摆线磨齿机进行改装。这台机床已严重地失去精度,改装后完全达到原设想要求.一、工作台上增加密封装置我们主要对下工作台进行改装。为了延长主轴滚动轴承的使用寿命,使带有砂粒的冷却油不能进入主轴滚动轴承的滚道内,保持四套 D 级轴承应有的精度,必须增加密封装置(如图).因此我们在下工作台上面换一只法兰3,在法兰正面装一只骨架油封,背面装一只 O 型油封。我们在原主轴锥度处镶一只轴套5,
In May, 81, we published a paper titled “Repair of Cycloid Grinding Machine Precision” and got the help and advice of many readers. In order to further solve the QC001 cycloid gear grinding machine accuracy and service life, we are an old cycloid gear modification. This machine has been severely lost accuracy, modified fully meet the original design requirements. First, increase the sealing table on the workbench We mainly on the next table to be modified. In order to extend the service life of the spindle rolling bearing, the cooling oil with sand can not enter the raceway of the spindle rolling bearing, to maintain the accuracy of four sets of D-class bearings, the sealing device must be added (Figure). A flange 3, the front of the flange with a skeleton seal, the back of an O-shaped seal. We set a spindle sleeve taper at the original 5,
