这种自锁性能只能是手柄带动着齿轮轴的转动及齿条轴的移动，而不能是齿条轴带动着齿轮轴的转动。

This performance can only be handle driving a gear shaft to rotate and rack shaft to move, but not gear shaft drive gear shaft to rotate.

设计合理：采用先进的Y轴双齿条传动、速度快、力量大。

Resonable Designs: advanced rack and pinion drive in Y axis with larger speed and strength.

另外，到r11在接受轴齿轮齿条式或电缆使用齿轮或滑轮测量。

Alternatively, the R11 shaft accepts pinions or pulleys for use in rack and pinion or cable measuring systems.
