| description | The utility model discloses a labyrinth type sealing structure, which belongs to the field of machine tools and comprises a mandrel, a flange, a mandrel gland and a flange gland, the mandrel gland is fixed at the front end of the mandrel, the mandrel is driven to rotate when rotating, the flange gland is sleeved on the outer wall of the mandrel gland and fixed on one side of the flange, and the flange gland is sleeved on the outer wall of the mandrel gland. A first gap is formed between the mandrel gland and the flange gland, a second gap is formed between the mandrel gland and the flange, the first gap and the second gap are communicated to form a labyrinth seal which is used for preventing impurities such as cutting fluid from entering the bearing, and a sealing ring is still arranged at the position close to the bearing for final protection. The structure has multiple protections, the risk that impurities such as cutting fluid enter the bearing is effectively reduced, and the service life of the bearing is |
