The invention discloses a shell and a circulating ball type electric steering device. The device comprises: a main body structure, wherein the interior of the main body structure is internally provided with an inner wall, and the inner wall divides the interior of the main body structure into a recirculating ball speed reducing mechanism chamber and a worm gear chamber; and a third main body, wherein the interior of the third main body is provided with a worm chamber, and the worm gear chamber is communicated with the worm chamber to form a worm and gear reducing mechanism chamber; A screw bearing seat is arranged on the inner wall, and a worm bearing seat is arranged in the third main body. According to the device, the circulating ball screw and the worm can be effectively positioned, meanwhile, the mounting sizes of the worm gear and the worm are effectively controlled, manual axial clearance adjustment is not needed again, the situation that the product assembling quality is affected due to different skills of assembling personnel is reduced, therefore the assembling precision and the assembling efficiency are improved, the influence of human factors is reduced, and automatic production is easy to realize.

    本发明公开了一种壳体及循环球式电动转向装置,包括:主体结构,主体结构的内部具有内壁,内壁将主体结构的内部分隔形成循环球减速机构室和蜗轮室;第三主体,第三主体的内部具有蜗杆室,蜗轮室与蜗杆室连通以形成蜗轮蜗杆减速机构室;其中,内壁上设有螺杆轴承座,第三主体的内部具有蜗杆轴承座。本发明能够有效定位循环球螺杆和蜗杆,同时有效控制蜗轮和蜗杆的安装尺寸,不需要再次进行人工轴向间隙调整,减少因为装配人员技能不一而影响产品装配品质,从而提高装配精度和装配效率,减少人为因数的影响并易于实现自动化生产。
