机床高速轴的密封，有多种形式。如果高速轴轴承采用油液润滑，则传统的接触式和非接触式密封方式，都有一定程度的渗漏，密封效果不太好。 笔者提出了一种在专用机床上的动力头主轴新型结构，其密封的结构形式与装配关系如图所示。 主轴是通过前后端的 46200、 46300角接触球?
High-speed machine shaft seal, there are many forms. If high-speed shaft bearings with oil lubrication, the traditional contact and non-contact seal, there is a certain degree of leakage, the sealing effect is not very good. I proposed a new type of power head spindle on a special machine tool, the structure of the seal and the assembly as shown in the figure. Spindle through the front and rear 46200, 46300 angular contact ball?
