在使用螺丝车床的时候,由于电动机从正转变为反转的结果,机床的轴和电动机的轴经常被折断或者被扭弯。一种专门的离心摩擦离合器(参看图)可以消除这些缺陷,而且还能使电动机在启动的很轻快,没有冲击并能延长电动机的使用期限。 在接通电动机时,滑块由于离心力而压在轴套的内表 When using a screw lathe, the shaft of the machine tool and the shaft of the motor are often broken or twisted as a result of the motor turning from positive to reverse. A dedicated centrifugal friction clutch (see photo) eliminates these drawbacks, but also enables the motor to be brisk, shock-free and extend the life of the motor. When the motor is turned on, the slider presses against the inner surface of the sleeve due to centrifugal force
