把车床改装作铲削加工时,必须将主轴转速降低5倍。 由于不可能用调换皮带轮的方法来解决这一问题。故采用了如图所示的方法。轮子3是没有心轴的,三角度带2和4拉紧,悬浮在皮带1和5之间。 这种改变转速的方法非常简单。所需要的零件,每个车间都可自行制造。 一年来,三班制不停歇 When turning a lathe into a shovel, you must reduce the spindle speed by a factor of 5. Because it is impossible to replace the pulley method to solve this problem. Therefore, as shown in the method used. The wheel 3 has no mandrel, the tangential belts 2 and 4 taut, and are suspended between the belts 1 and 5. This method of changing speed is very simple. The required parts, each workshop can be manufactured. Over the past year, three shifts do not stop
