The utility model provides a technical scheme that above-mentioned problem adopted is: a cleaning device for a gear ring internal gear polishing wheel comprises a supporting seat, wherein annular grooves are symmetrically formed in two sides of a projecting shaft of the supporting seat, a small shaft is integrally arranged at the lower part of the projecting shaft, and a fastening part is arranged at the bottom of the small shaft;
the upper end of the polishing wheel is tightly sealed and fastened with the supporting seat through a first star-shaped sealing ring, and the first star-shaped sealing ring is arranged in the annular groove;
the lower end of the polishing wheel is fastened on the supporting seat through a nut;
the polishing wheel and the nut are sealed by a second star-shaped sealing ring and a gasket;
the inner hole of the polishing wheel is in clearance fit with the diameter of the support seat protruding shaft;
and the diameter of a bearing inner hole of the polishing wheel is larger than that of the small shaft.
Preferably, the nut is an outer hexagonal nut, and the outer hexagonal nut is matched with the fastening part in a working condition.
Preferably, the supporting seat and the nut are made of stainless steel, so that rusting is prevented.
Compared with the prior art, the utility model, have following advantage and effect: 1. the utility model designs a centering structure, the inner hole of the polishing wheel is in large clearance fit with the diameter of the projecting shaft of the supporting seat, the bearing inner hole of the polishing wheel is larger than the diameter of the small shaft, and the bearing inner hole can be effectively prevented from being scratched; 2. the upper end face and the lower end face both use star-shaped sealing rings, so that cleaning agents can be effectively prevented from entering the inside of the bearing during cleaning and polluting lubricating oil; 3. the nut is adopted for installation and fastening, so that the disassembly and the use are convenient.
