2.
In order to reduce error on copying machine and exceed movement performance of primitive cam,reverse kinematic regulation on gripper opening and closing mechanism of vector single sheet offset was studied.
为减小复制进口机器凸轮时的误差,使复制的凸轮具有或超过原始凸轮的运动性能,通过运用矢量法对某企业生产的单张纸胶印机咬纸牙开闭机构中,凸轮的运动规律进行反求,得到了类似于简谐运动的实际从动件运动规律,从而为分离出原始开闭牙凸轮的综合误差,改进从动件的运动性能,提高整机的动态工作性能提供科学依据。
4) drive mechanism
驱动机构
1.
Research on model experiment for electromagnet drive mechanism;
电磁铁驱动机构模型的实验研究
2.
Based on the fundamental research of the hydraulic control rod driving system, which invented by Tsinghua University, and combined with the advantage of the magnetic jack in press water reactor (PWR), the control rod hydraulic drive mechanism was developed as a new type internal control rod drive technology.
该驱动技术解决了磁力提升器把驱动机构置于核反应堆压力壳外的缺点,但保留了抓式机构驱动的优点;解决了水力驱动控制棒系统动压驱动因工况变化而引起的驱动特性的复杂性的缺点,继承了内置式控制棒驱动机构不贯穿压力壳、传动线短、避免了弹棒事故等优点。
3.
The new drive mechanism for the double knife cutter bar of self propel Combine harvester with rubber crawlers have been development.
研究表明,利用双层联动摇杆机构可减少位于收割外侧的驱动机构宽度,不影响联合收割机下田作业时开道;利用杠杆支点两端运动方向相反的力学原理,可带动上下动刀做反方向同步运动;通过机构综合确定联动杆尺寸,可使上下动刀驱动销获得绝对值相等的运动速度,从而保证了双动刀往复式切割器实现方向相反、速度相等的切割运动。
