棘轮

The center of balls in bearing is fixed by the fork of locating sleeve. The cooperation between linkage pin, grip slot of drive axle and ratchet wheel is used to make the drive axle and driven axle rotate in same or different directions for threading or turning back.

本攻丝装置由拨叉定位套上的拨叉将轴承中滚珠的中心固定，利用联动销与主动轴的卡槽和棘轮的配合，实现主动轴与从动轴的同向转动和反向转动，完成丝锥正转攻丝和自动反转退出工件工作。

The damage of the derrick was due to the careless handling of the ship's crew in lowering the derrick, causing the topper to override the ratchet wheel and foul onto the topping winch drum shaft.

该吊杆的损坏是由于该轮船员在将吊杆放低时因操作不慎而造成千斤索越过棘轮，缠绕在千斤索绞车卷筒轴上。

Ash removal mechanism : ash is removed by hydraulic ratchet wheel and detent from both sides. A self-designed plough-type tool is adopted, which is featured as steady drive and smooth ash removal. Our plough-type tool has been used in many types of domestic and imported coal gasifiers and is well received.

Some key part is ameliorated to meet the demands of working. This thesis mainly includes:(1) Analysing the working principle of the spring operateing mechanism, expatiating the character of the mechanism;(2) With the design aim of the spring operating mechanism, accomplishing the design of ZW□-12/630-20 outdoor HV vacuum breaker based on the systemic design theory of the spring operating mechanism, which includes spring mechanism of open-close switch; cam mechanism based on the principle of power balance; buckle-off mechanism with force-minished device; ratchet wheel mechanism with number-increased detent;(3) In the design on the spring operating mechanism for the outdoor vacuum breaker, using the air cushion device with speed controller to ensure the steady working of the spring operating mechanism;(4) Accoding the problem of daily maintenance for HV circuitbreaker, giving some effective steps of daily maintenance.

论文工作主要包括以下几个方面：(1)从真空断路器弹簧操动机构的功能原理出发，详细分析了该机构的工作原理，阐述了机构工作的基本特性；(2)根据工程实际提出了真空断路器弹簧操动机构的设计目标，在系统分析弹簧操动机构设计理论的基础上，完成了ZW□-12/630-20型户外真空断路器弹簧操动机构的设计工作，其中包括真空断路器弹簧操动机构的分合闸弹簧机构的设计；以输出力特性曲线设计机构理论演化出的功率平衡原则为基础的凸轮机构的设计；带有减力机构的滚动摩擦扣结方式的脱扣机构设计；根据实际情况增加了棘爪数量的棘轮机构设计；(3)在真空断路器弹簧操动机构的设计中，引入了速度控制模式空气缓冲器，对惯性负载起到了良好的自动缓冲效果，从而保证了真空断路器弹簧操动机构稳定、有效地运行，保证了真空断路器的动作质量；(4)针对目前真空断路器运行过程中存在的问题，提出了有效的日常维护措施。

When a spiral coil spring rotates an adapter while the webbing belt is fitted and a plunger is coupled with a ratchet wheel, a torsion coil spring is wound on the adapter.

安全带被系上后，在一根冲杆卡住一个棘轮的状态下，当一个盘簧转动一个承接件时，一根扭转螺旋弹簧在承接件上旋紧。

Consequently, the topper was cut broken by the pawl of the ratchet wheel and the derrick fell freely and struck onto the bulwark top, resulting into serious bending of derrick and also wounding of stevedores.

接着，千斤索被棘轮爪切断，吊杆失控跌落并撞上舷墙顶部，致使吊杆严重弯曲，装卸工受伤。
