Description

Technical Field

[0001] The utility model relates to the technical field of gear oil pumps, in particular to a sealing structure for a gear oil pump. Background Art

[0002] The gear oil pump is a mechanical device used to transport lubricating oil and grease. Its main principle is to generate a vacuum through the rotation of the gears, thereby attracting the lubricating oil into the pump body, and then transporting the lubricating oil to the parts that need lubrication.

[0003] The gear oil pumps currently used usually rely on flange structures for sealing connections when connecting to external oil supply access pipes. When the flange body or the pipe connection is subjected to external impact, the flange body and the pipe connection may be deformed and damaged, causing oil leakage, thereby affecting the sealing effect inside the pipe. For this reason, we propose a sealing structure for gear oil pumps. Utility Model Content

One end of the two embedding rings 13 extends to the inside of the two annular embedding grooves 12 respectively, and the outside of the embedding ring 13 fits with the inner wall of the annular embedding groove 12.
