This avoids the use of a traditional propeller shaft and puts the propellers in a clear flow of water, which greatly improves efficiency.

这样就避免了使用传统的螺旋轴，将螺旋桨置于干净的水流中，从而大大提高了效率。

However, the greater the displacement of the input shaft axis from the crown wheel axis, the lower the mechanical efficiency.

然而，更大的车轮从冠轴输入轴轴线位移，机械效率降低。

The increase of the wheel speed, the swing frequency and the feed of shaft direction conduce to improving the grinding efficiency.

增加砂轮转速、砂轮摆动和轴向进给量可以提高单晶金刚石的研磨效率。
