测量不同转速时的齿杆行程。
本文通过对活塞杆行程原理设计制动间隙自动调整机构的结构分析，详细地讨论了制动间隙自调机构的工作原理以及主要零件的设计方法。
This article mainly analyses the structure of the ACAD . Base on the analysis, there comes out the operating principle of the ACAD and the design for the major components.
提出了一种大功率、大负载、长行程工作条件下，液压缸活塞与缸体之间、活塞杆与缸盖之间密封方式的设计方案。
Design blue print of the hydraulic cylinder seal style was put forward for the hydraulic cylinder with large power, larger load and long journey.
为什么直行程调节阀阀杆较细？
阀杆开启或关闭行程相对较短，并具有非常可靠的切断动作，使得这种阀门非常适合作为介质的切断或调节及节流使用。
Open or close the valve stem travel relatively short, and very reliable cutting action, making this valve is suitable for medium and cutting off or regulating use.
分析了在采用杠杆放大行程的情况下，用仿形模板控制杆端轨迹的原理。
With the travel enlarged by means of profiling plates, how the orbit of the lever end is controlled by profiling plates is analysed.
手动按压部分由按压杆带动滑柱及按压头向下运动，并通过限位环来控制按压头的行程；
The manual pressing section makes the downward movement by a slide cylinder and a pressing head driven by a pressing rod, and the travel of the pressing head is controlled by a limited ring;
操纵杆作用力和行程的减小使工作装置的操作变得容易。
The reduction in the lever force and travel makes it easy to operate in the work environment.
但是也有人就称之为：自锁型气动杆，其实所谓的自锁型气弹簧也好调角器也好，都是一种可以在行程任一位置锁定的气弹簧。
But there are people called: self-locking type pneumatic rod, in fact, lockable gas spring or the so-called Angle or is a kind of air spring can be locked in any position of the stroke.
为了预注行程，预注机构（35）相对于活塞杆（11，12）在驱前的方向（V）上可以移动。
The priming mechanism (35) for the priming stroke is movable relative to the piston rod (11, 12) in the direction of propulsion (V).
每个轴行程的滚珠丝杆。
自锁型气弹簧是一种可以在行程任一位置锁定的气弹簧。 在自锁型气弹簧的活塞杆端部有一个针阀打开这个针阀，则自锁型气弹簧可以象自由型气弹簧那样运行；
The piston rod self-locking type gas spring end there is a needle valve open the needle valve is self-locking type gas spring can run as the free type gas spring;
不要出现在行程较长时抖动，有利于确保扫描精度，稳定的运动。使用线性步进电机直接连接滚珠丝杆、响应更加快速准确，因为没有中间部分同时，简化了机械结构，精度高。
Using linear stepper motor directly connected ball screw, response more accurately, because there is no middle part at the same time, simplify the mechanical structure, high precision.
