摘要： An electric linear actuator has a housing, an electric motor, a speed reduction mechanism and a ball screw mechanism. The ball screw mechanism has a nut and screw shaft. A blind bore is formed on the housing. The blind bore contains an end of the screw shaft. An anti-rotation mechanism for the screw shaft has a sleeve and guide pin. The sleeve is press-formed from steel sheet and fit into the blind bore of the housing. The guide pin is mounted on the end of the screw shaft, via a through aperture formed in the screw shaft. The guide pin axially movably engages the sleeve.

摘要： An electric linear actuator has a housing, an electric motor mounted on the housing, a speed reduction mechanism, and a ball screw mechanism. The ball screw mechanism has a nut and screw shaft. Both have helical screw grooves. The screw shaft is inserted into the nut, via a large number of balls. A sleeve is secured on the housing to prevent rotation of the screw shaft relative to the housing. At least one axially extending recessed groove is formed on the inner circumference of the sleeve. At least one guide pin, mounted on the end of the screw shaft, engages the recessed groove. A tapering chamfered portion is formed on the end of the nut.
摘要翻译：电动线性致动器具有壳体，安装在壳体上的电动马达，减速机构和滚珠丝杠机构。滚珠丝杠机构具有螺母和螺杆轴。两者都有螺旋形螺纹槽。螺杆轴通过大量的球插入螺母。套筒固定在壳体上以防止螺杆轴相对于壳体旋转。在套筒的内圆周上形成至少一个轴向延伸的凹槽。安装在螺杆轴的端部上的至少一个引导销接合凹槽。在螺母的端部上形成锥形倒角部分。
