D012(旧型号132/1M)球轴承外沟检查仪系苏联原设计的一种轴承专用检查仪器,专门用于球轴承外圈滚道磨加工工序及零件最后检查.目前在国内轴承工业中被广泛采用.但是,通过几年来的实践证明,由于该仪器本身设计上的某些不合理的地方而造成仪器测量误差较大,测量力不易调整等,归纳起来,主要有下列缺点:1.仪器定位系采用等腰三角形三点接触分布,以致测量误差较大,示值不能正确反映工件实际尺寸之大小.
D012 (old model 132 / 1M) ball bearing outer groove tester is the Soviet Union originally designed a special bearing inspection equipment, specifically for ball bearing outer ring raceway grinding process and the final inspection parts.Now in the domestic bearing industry was Widely used.However, through years of practice has proved that due to the design of the instrument itself some of the unreasonable places caused by the measurement error of the instrument is difficult to adjust the measurement force, etc., in summary, the following disadvantages: 1. Instrument Positioning system uses isosceles triangle contact distribution, resulting in large measurement error, showing the value can not correctly reflect the size of the actual size of the workpiece.
