阅读说明：本技术 齿轮箱组件 (Gear box assembly ) 是由 M·阿普尔亚德 于 2018-06-29 设计创作，主要内容包括：披露了一种用于电动动力辅助转向设备的齿轮箱组件,该齿轮箱组件包括：齿轮箱壳体,该齿轮箱壳体容纳蜗杆轴和蜗轮,该蜗杆轴承载蜗杆齿,该蜗轮具有一组蜗轮齿,蜗杆轴相对于壳体在距马达最近的一端由主轴承组件支撑,并且在距马达最远的一端由尾部轴承组件支撑,并且蜗轮由输出轴支撑,该输出轴具有从齿轮箱组件取力的至少一个端部。第一支点装置定位在主轴承组件的第一侧,该第一支点装置仅对蜗轮转矩的第一方向的蜗杆轴齿载荷的轴向分量起反作用,并且第二支点装置定位在主轴承组件的相反的第二侧,该第二支点装置仅对蜗轮转矩的第二方向的蜗杆轴齿载荷的轴向分量起反作用,第一支点和第二支点与主轴承组件的接触点限定了轴线,主轴承组件能够绕该轴线枢转。(A gearbox assembly for an electric power assisted steering apparatus is disclosed, the gearbox assembly comprising: a gearbox housing containing a worm shaft carrying worm teeth and a worm gear having a set of worm gear teeth, the worm shaft being supported relative to the housing at an end closest to the motor by a main bearing assembly and at an end furthest from the motor by a tail bearing assembly, and the worm gear being supported by an output shaft having at least one end which is weighted from the gearbox assembly. A first fulcrum arrangement is positioned on a first side of the main bearing assembly, the first fulcrum arrangement reacting only to an axial component of the worm shaft tooth load in a first direction of the worm gear torque, and a second fulcrum arrangement is positioned on an opposite second side of the main bearing assembly, the second fulcrum arrangement reacting only to an axial component of the worm shaft tooth load in a second direction of the worm gear torque, contact points of the first and second fulcrums with the main bearing assembly defining an axis about which the main bearing assembly is pivotable.)
