蜗轮减速机在机械传动中应用很广,零件质量对减速器的性能影响很大,尤其是箱体两孔中心距误差直接影响到蜗杆副的啮合精度,可是以往加工后箱体的中心距一般都采用常规的方法检测,这种测量误差大、效率低、工作繁琐。为此,我们设计制造了空间两相交孔距测量仪。如图所示,量具分两部分:一部分由通用内径量表1,定位块2、螺钉3、表轴4、动测头5和定位锥套 Worm gear reducer is widely used in mechanical transmission, the quality of the parts have a great impact on the performance of the reducer, especially the center hole distance error of the box directly affects the meshing accuracy of the worm pair, but the center of the box after the previous processing is generally Are using conventional methods of detection, this measurement error, low efficiency, tedious work. To this end, we have designed and manufactured a space intersection of two cross-gauge. As shown in the figure, the gauge is divided into two parts: one part is composed of a universal inner diameter gauge 1, a positioning block 2, a screw 3, a shaft 4, a moving probe 5 and a positioning sleeve
