一、轴承原理图1是轴承的截面图,轴承是由三个轴瓦,三个弹性变形部和轴承端挠性部的调整螺纹的构成。图2是轴瓦和主轴之间的关系,(a) 表示的是轴承装配前的状态,(b) 是装配后的状态,(c) 是主轴回转时的状态。轴承经最后的研磨,精加工成如图2(a)所示的一个圆柱面,再装入如图3所示的套筒,利用调整螺纹拉入6°的锥孔内。这时,各轴瓦如图2(b)那样向着轴心方向作微量位移,并尽可能不要使各个轴瓦的曲率半径发生变化,这对轴承有效
First, the principle of the bearing Figure 1 is a cross-sectional view of the bearing, the bearing is composed of three bushings, three elastic deformation of the Ministry of flexibility and the adjustment of the bearing-side thread. Fig. 2 shows the relationship between the bush and the main shaft. Fig. 2 (a) shows the state before bearing assembly, (b) after assembly, and (c) when the main shaft is rotating. After final grinding, the bearing is finished into a cylindrical surface as shown in FIG. 2 (a), and then a sleeve as shown in FIG. 3 is drawn into the tapered bore of 6 ° by using an adjusting thread. At this time, as shown in Figure 2 (b) as the axis of the bush toward the direction of the micro-displacement, and as far as possible not to make the radius of curvature of each bearing change, which is effective bearing
