上海重型机床厂79年以前制造的 C 61100车床的主轴制动采用的是电磁铁一重镇结构(参见图1)。 当电磁铁失电时重锤下落, 通过一组杠杆与开合涨圈使 制动轮迅速刹住。虽然设计 上有缓冲弹簧,但当重锤落 到最低处时仍有一定的速 度,会引起振动,在点动时 更加厉害,由此产生一些不 The spindle brake of the C 61100 lathe, which was manufactured 79 years ago by Shanghai Heavy Duty Machine Tool Works, uses an electromagnet-heavy town structure (see Figure 1). When the electromagnet lose weight when the hammer fell, through a set of lever and opening and closing rings make the brake wheel quickly stopped. Although the design of the buffer spring, but when the hammer fell to the lowest there is a certain speed, will cause vibration, the more powerful when the move, resulting in some not
