主轴密封结构及作业机械
By designing a spindle sealing structure, positive pressure is generated by the rotation of the outer cone sleeve and the dustproof impeller. Combined with multi-layer sealing, the problem of dust entering the bearing cylinder is solved, and stable operation of the bearing and spindle is achieved.

AI Technical Summary
In existing technologies, dust can easily enter the bearing housing through the sealing mechanism, affecting the operation of the bearing and spindle, leading to increased bearing temperature and wear.
A spindle sealing structure was designed, including an outer conical sleeve, a dustproof impeller, a bearing sleeve, first and second end covers, and a sealing cover. The rotation of the outer conical sleeve and the dustproof impeller creates positive pressure in the chamber, reducing dust entry. Combined with the multi-layer sealing structure, the sealing effect is improved.
It effectively reduces the risk of dust entering the bearing housing, ensures long-term stable operation of the bearing and spindle, and prevents bearing temperature rise and wear.
