为了满足轴承生产的要求,我所研制了一种高效率、高精度、结构简单、价格低廉,适合于生产现场使用的轴承圆度仪—高速圆度仪。一、高速圆度仪的特点和原理高速圆度仪(图1)采用半径法测量圆度,测量时工件旋转(最高转速750转/分)。可测最大外径φ30与φ250;最小内径φ3与φ17;旋转精度0.03～0.06微米与0.06～0.08微米;采用最小二乘方中心圆法评定圆度;量程分挡0.3,1,10,30微米;测量波数分挡1～500,2～500,2～15,15～500,1波;被测件轮廓
In order to meet the requirements of bearing production, I developed a high efficiency, high precision, simple structure, low cost, suitable for production site use bearing roundness - high speed roundness meter. First, the characteristics and principles of high-speed roundness meter High-speed roundness meter (Figure 1) using the radius method of measuring roundness, the workpiece rotation measurement (maximum speed of 750 rev / min). Measurable maximum outer diameter φ30 and φ250; minimum inner diameter φ3 and φ17; rotation accuracy of 0.03 to 0.06 microns and 0.06 to 0.08 microns; roundness method using the least square method for the assessment of roundness; range of sub-0.3,1,10,30 micron ; Measured wave number block 1 ~ 500,2 ~ 500,2 ~ 15,15 ~ 500,1 wave; measured profile
