This integral structure is relatively complex, which leads to a relatively complex mold structure. Therefore, it has the disadvantages of high equipment investment cost, high product scrap rate and high manufacturing cost.

[0003] Chinese patent document CN102349820A discloses a structure for a vacuum cleaner roller brush gear shaft. This invention presents the gear and brush shaft as separate components. The brush shaft has splines, and an annular groove is located on the side of the brush shaft adjacent to the splines. The gear is mounted between the splines and the annular groove on the brush shaft. The gear portion corresponding to the splines has only internal splines that communicate with each other. The splines and the internal splines of the gear portion achieve circumferential positioning. Several circumferentially distributed catches are formed on the gear corresponding to the annular groove. The catches engage within the annular groove, enabling axial positioning between the gear and the brush shaft. This invention has the advantages of lower equipment investment costs, lower product scrap rates, and lower manufacturing costs.
