Electric motors in other countries may operate at 1350 RPM so a different reduction gear set will be required.

在其他国家电动机可运行在1350转这样一个不同的减速将需要设置。

In a gear reduction unit, for example, the shaft diameters are usually set by the requirement of getting sufficient shaft stiffness to keep the misalignment of the gear teeth within strict bounds.

例如，在齿轮减速装置中，轴径通常是由轴的刚度要求决定以在严格界限内保持齿轮齿形的不错位。
