Abstract: A circulation member positioning structure for a ball screw includes a nut and a circulation member. The nut has a threaded channel, a socket, and a positioning notch. The socket is provided on a wall of the threaded channel and the positioning notch is provided on a wall of socket. The circulation member has a circulation portion, a circulation track a positioning protrusion. The circulation portion is provided in the socket of the nut. The circulation track is distributed over one lateral of the circulation portion and connects with the threaded channel of the nut. The positioning protrusion is provided on an opposite lateral of the circulation portion for being engaged with the positioning notch of the nut. Thereby, the circulation member positioning structure helps to simplify the assembling work of the circulation member and to remain the nut small. despite the insertion of the circulation member.

Abstract translation: 用于滚珠丝杠的循环构件定位结构包括螺母和循环构件。 螺母具有螺纹通道，插座和定位槽。 插座设置在螺纹通道的壁上，并且定位槽口设置在插座的壁上。 循环构件具有循环部，循环轨道，定位突起。 循环部设置在螺母的插座中。 循环轨道分布在循环部分的一侧，并与螺母的螺纹通道连接。 定位突起设置在循环部分的相对侧面上，用于与螺母的定位槽口接合。 因此，循环构件定位结构有助于简化循环构件的组装工作并且保持螺母较小。 尽管插入循环构件。
