滚道是ZX系列振动器的重要零件,其锥孔的制造精度直接影响振动器的性能。为了提高滚道锥孔的测量精度,目前各振动器厂均采用钢球法代替锥度塞规法进行检测。但在使用钢球法中还存在着一些问题,本文拟就这些问题谈谈看法。一、圆锥公差标注的两种方法圆锥公差的标注有两种方法:基本锥度法和公差锥度法。1.以ZX50振动器为例,振动器行业统型图纸滚道零件图中圆锥公差的标注如图1所 Raceway is an important part of the ZX series vibrator, the manufacturing accuracy of the cone bore directly affects the performance of the vibrator. In order to improve the measurement accuracy of raceway taper hole, each vibrator factory adopts steel ball method instead of taper plug method to detect. However, there are still some problems in the use of steel ball method, this article intends to talk about these issues. First, the two methods of coning tolerance Marking of conical tolerance There are two ways: basic taper method and tolerance taper method. 1 to ZX50 vibrator, for example, the vibrator industry standard drawings raceway parts diagram cone tolerance marked as shown in Figure 1
