Because an eccentric can be attached anywhere along a shaft, it is unnecessary to form any part of the shaft into a crank.

由于偏心轮可装于轴的任何部位，不必把主轴作成曲柄。

At one end of the inner ring, the bearing is clamped to the shaft with an eccentric locking ring (Figure 1.7) or with two setscrews (Figure 1.8).

在内圈的一端，轴承通过偏心锁定环(图1.7)或者两个定位螺钉(图1.8)被固定在轴上。
