The invention relates to an automobile electric power steering gear with a lubricating grease supplementing structure and a lubricating grease supplementing method. The invention belongs to the technical field of automobile electric power steering gears. A lubricating grease supplementing mechanism is arranged on the steering gear shell corresponding to the meshing portion of the worm gear and the worm and used for filling and supplementing lubricating grease to the meshing portion of the worm gear and the worm, so that lubrication between the worm gear and the worm is guaranteed, and dry grinding noise and abrasion between the worm gear and the worm caused by lack of the lubricating grease are avoided. According to the electric power-assisted steering gear, lubricating grease can be injected and supplemented to the meshing position of the worm gear and the worm in time through the lubricating grease supplementing mechanism, and lubrication between the worm gear and the worm of the power-assisted steering gear is guaranteed; the problem that base oil of existing steering gear lubricating grease is easy to separate out during meshing of a worm gear 3 and a worm 4 is effectively solved, and the lubricating grease has positive significance for improving the quality and prolonging the service life of a power-assisted steering gear.

    本发明涉及一种带有润滑脂补充结构的汽车电动助力转向器及润滑脂补充方法;属汽车电动助力转向器技术领域。转向器壳体上对应蜗轮和蜗杆啮合部位设置有润滑脂补充机构,用于对蜗轮和蜗杆的啮合部位进行加注补充润滑脂,从而保证蜗轮蜗杆之间的润滑,避免润滑脂的缺失所导致的蜗轮和蜗杆之间的干磨音和磨损。该电动助力转向器通过润滑脂补充机构可及时对蜗轮和蜗杆的啮合位置进行润滑脂的注入补充,保证了助力转向器蜗轮和蜗杆之间的润滑;有效解决了现有转向器润滑脂基础油易在蜗轮3和蜗杆4啮合中析出,对助力转向器的质量、寿命提高具有积极的意义。
