Abstract螺杆螺母副的轴向滑动导向机构,包括螺杆与旋转螺母构成传动副的动力传递部分,和设在螺杆上的轴向导向机构,轴向导向机构由轴向滑动导向部分和圆柱面定心部分组成,丝杠或螺杆与旋转螺母外面设有轴承座外壳,旋转螺母通过滚动轴承被支承在轴承座外壳内;轴向导向机构座通过联结螺钉与轴承座外壳连接;楔形块、导向滚针和支撑滚针安装于轴向导向机构座梯形孔内;紧定调节螺钉通过挤压楔形块传递力到支撑滚针、导向滚针、丝杠或螺杆的轴向滑动导向面部分,紧定调节螺钉挤压力方向与轴向滑动导向面的反作用力呈90度角;丝杠或螺杆轴向滑动导向面部分在轴向导向机构座中心方孔中。本发明的结构简单,加工容易,成本低廉,使用效果良好。
