Technical Field

[0001] The utility model relates to the technical field of sealing of magnet processing equipment, and in particular discloses an oil leakage prevention lubrication structure for magnet processing equipment. Background Art

[0002] In modern industrial equipment, magnet drilling machines are an important tool and are widely used in drilling operations of various materials. With the increase of usage frequency and work intensity, the shaft and related components in the magnet drilling machine often face serious wear problems, which directly affects the service life and work efficiency of the equipment. Therefore, how to effectively reduce the wear between the shaft and the box body and extend the service life of the equipment has become a technical problem that needs to be solved urgently.

During long-term and high-intensity use, the friction of the bearings will cause bearing wear, which will affect the accuracy and stability of the equipment. In addition, due to unreasonable lubrication system design or insufficient sealing performance, lubricating oil is prone to leakage, which not only increases the maintenance cost of the equipment, but also may pollute the environment.

[0008] Furthermore, the sealing assembly is provided with two groups, and the two groups of sealing assemblies are respectively located on two sides of the box body away from each other. The two groups of sealing assemblies are respectively located on two sides of the box body, further enhancing the sealing effect.
