TBI直线导轨_滚珠丝杆的精确度

 荣誉资质     |      2019-07-16 16:18

     滚珠丝杆的导程越小,所转化的直线活动越周详,它的精度也越高。

    导程:指统一螺旋线上相邻两牙对应点的轴向距离。用代号S表现。它与螺距分歧,螺距指的是罗纹上相邻两牙对应点的轴向距离,代号是P。复线罗纹的导程即是螺距,多线罗纹的导程即是头数(n)乘以螺距,即 S=nP。

    滚珠丝杆是比拟常用的标准件,精度较高,稳固性好,运行中噪声小,信任有很多人都用过。

    很多多地位高精度的用处的模组,小我也会优先斟酌应用丝杆组件。滚珠丝杆非预压型的,多数会有轴向间隙,分歧精度品级的丝杆,轴向间隙也就分歧,平日来讲研磨丝杆的精度要好于压轧丝杆。
