要保证螺纹磨床磨出的螺纹达到预定的几何精度和光洁度,特別是减少波纹,磨头组件是重要的环节。在磨削时必须保证砂轮主轴具有较高的回转精度,抗振性好,轴承的温升在规定的范围内。为此,必须使砂轮主轴和轴承修复至要求。现将我们的具体做法介绍如下。一、砂轮主轴组件图1是砂轮主轴组件的结构简图。砂轮主轴在两端整体薄壁弹性变形或动压滑动轴承中旋转。在轴承外面有一个内锥外圆柱形的淬火衬套,衬套装在砂轮主
To ensure that the thread grinder threads to achieve the desired geometric accuracy and finish, especially to reduce the ripple, grinding head assembly is an important part. Grinding must ensure that the grinding wheel spindle has high rotary accuracy, good vibration resistance, bearing temperature rise within the specified range. For this reason, the wheel spindle and bearing must be repaired as required. Now we will introduce the specific practices below. First, the wheel spindle assembly Figure 1 is the wheel spindle assembly diagram. Wheel spindle at both ends of the overall thin-walled elastic deformation or dynamic pressure sliding bearing rotation. Outside the bearing there is a cylindrical outer quench bushing, bushings installed in the wheel main
