库伊贝舍夫斯基工学院(独联体)研制了一种砂纸片砂轮,其结构见图1。该砂轮由于能改变工作部分的几何参数,因此具有较高的工作效率。该砂轮包括带偏心凸肩的基座2,法兰盘4和压紧圆盘6,在圆盘6上安装法兰盘5。上述零件的内孔或凸肩都带有偏心量。法兰盘4的内孔与基座2凸肩的偏心量相同,而法兰盘 Kuybevschevski Institute of Technology (CIS) developed a sandpaper wheel, the structure shown in Figure 1. The wheel can change the working part of the geometric parameters, so with high efficiency. The grinding wheel comprises a base 2 with an eccentric shoulder, a flange 4 and a pressing disk 6 on which the flange 5 is mounted. The parts bore or shoulder with eccentricity. Flange 4 and the base bore hole 2 eccentric amount the same shoulder, and flange
