M7130、M7132H类平面磨床,削轴承为外圆锥体内圆柱体滑动轴承,后轴承为滚动轴承,前后两轴承相互之间的位置距离相隔很远。主轴后端所装的(电机)转子的两头分别有11片各为长66mm,宽32mm、厚8mm的铸铝散热片。它与转子硅钢片浇铸为一体,因为是铸造铝,脆性大,各散热片体形尺寸小而且又长,故强度很差。转子与主轴的配合为H7/k6。经过长时间的使用,热胀冷缩使两者的结合有变紧现象,使转子要从主轴上拆卸下来很困难。 拆卸和重装的方法很多,主要步骤:拆卸拉出转子和风扇叶片→检查校对→修磨研抛光新主轴→ M7130, M7132H type surface grinder, cut the bearing cylindrical roller bearing outer cone, the rear bearing is a rolling bearing, bearing the distance between the two bearings are far apart from each other. The back end of the spindle installed (motor) rotor has 11 at each end of the long 66mm, width 32mm, thickness 8mm cast aluminum heat sink. It is cast with the silicon steel rotor as a whole, because it is cast aluminum, brittle, the heat sink body size small and long, so the strength is poor. Rotor and spindle with H7 / k6. After a long period of use, thermal expansion and contraction make the combination of both the phenomenon of tightening, the rotor from the spindle to remove it is very difficult. There are many ways to disassemble and reinstall, main steps: disassembling and pulling rotor and fan blades → checking proofing → grinding and polishing new spindle →
