Technical Field

[0001] The utility model relates to the technical field of bearing connection, in particular to a dust removal fan bearing connection closed structure. Background Art

[0002] A bearing is a mechanical component that is mainly used to support rotating or reciprocating mechanical devices and reduce friction. Bearings are usually composed of inner and outer rings, rolling elements, cages and sealing devices. They can limit the movement of the shaft within the required range, while reducing the friction resistance of the movement, making the machine run more smoothly and reliably. Bearings are widely used in various mechanical equipment, such as automobiles, aircraft, machine tools, household appliances, etc. Since bearings play a vital role in mechanical systems, they are sometimes figuratively likened to joints in the mechanical industry.

[0003] A dust removal fan bearing chamber structure disclosed in the Chinese utility model patent application disclosure CN205036621U includes a bearing chamber body, two ends of the bearing chamber body are transparent covers, two ends of the transparent cover are provided with pressure covers, a felt seal is provided between the transparent cover and the pressure cover, the inner space of the bearing chamber and the contact end of the impeller are provided with a first oil receiving pan, a second oil receiving pan, a first oil baffle ring, and a second oil baffle ring, the first oil baffle pan is fixed with the transparent cover by screws, the first oil baffle ring is spot welded on the bearing lock nut, the second oil receiving pan and the labyrinth ring are integrally provided, and the second oil baffle ring is interference fit with the shaft diameter. The utility model has a reasonable structural design, and the sealing effect is enhanced by providing the oil receiving pan and the oil baffle ring, so that the bearing chamber forms a closed loop, which can ensure that the oil splashed from the bearing is caught by the oil receiving pan and reused, and a small amount of oil flows through the gap between the oil receiving pan and the oil baffle ring, and under the action of the felt and the labyrinth ring, it flows back to the oil pool of the bearing chamber through the oil unloading hole, so that the sealing effect is good, waste is reduced, and the use cost is saved.
