Further, the external arc auxiliary groove and the internal arc auxiliary groove are the same in size, and a limiting ball is arranged between the external arc auxiliary groove and the internal arc auxiliary groove.
Further, a gap is reserved between the outer side wall of the sealing head and the inner side wall of the sealing groove.
Further, the left opening of the transmission hole is smaller than the right opening.
The dustproof and waterproof protection structure for the generator bearing has the beneficial effects that the sealing head of the integrated structure is arranged on the left side of the front cover of the generator, the sealing groove is arranged at the corresponding position on the right side of the belt pulley, the external impurities are discharged by arranging the guide sliding groove on the inner wall of the outer side of the sealing groove, the spiral guide surface is arranged on the inner wall of the inner side of the sealing groove, the internal impurities are discharged, the sealing performance and the safety of the whole generator connecting end are greatly improved, the early failure of the bearing is avoided, the service life of the bearing is prolonged, and the reliability of the generator is improved.
Drawings
The invention will be further described with reference to the drawings and examples.
Fig. 1 is a schematic structural view of the present invention.
