例句与用法

1.Technology of loxodrome coolant channel machining on liquid rocket engine . yuhang xuebao / journal of astronautics . vol . 24 no . 3 . may , 2003 . wang yongqing , lu jiechi , tong yu
等倾角螺旋槽的片铣刀铣削加工技术.工具技术. 2002年第8期. 2002年8月.王永青,卢杰持

2.On this base , it is studied that the general principle of normal circular - arc gear transmission , and with the instruction of which , the principle and technology of the loxodrome normal circular - arc spiral bevel gear transmission is studied
在这一原理指导下,论文从解析研究与实验研究结合上,研究了斜航式法向圆弧螺旋锥齿轮传动技术。

3.The directrixes of the in former two transmissions are the loxodrome and the geodesic on the pitch cones , that of the latter is an equal - pitch line along the direction of straight generatrixes in the hyperboloid surface , also is the vertical trajectory of the straight generatrixes
前两种传动形式的准线分别为节锥面上的斜航线与测地线,后者的准线为单叶双曲面上沿直母线方向的等螺距曲线,且为直母线族的正交轨线。

4.Disigning coolant channel on the firebox of liquid rocket engine to loxodrome ( equal - angle helix ) groove can improve firebox coolant capability greatly . because the width dimension of loxodrome groove is narrow and the depth is deep , some machining methods are incapable , such as end - milling or electrochemistry . according to the peculiarities , a cnc disk - cutter - milling method which is composed of five motion axes with four simultaneously interpolated ones is researched . because most firebox generatrix is composed of complex curves , it is very difficult to get cnc cutting program with manual means . in order to deal with the problem , the loxodrome mathematics model is studied , and an auto - programming software system is developed . the software system can generate cnc cutting program of loxodrome on many kinds of turned surface . the constriction - distension segment of firebox is the most representative workpiece . the sharp changing of its generatrix slope makes loxodrome milling difficult . with the theory analyzing and practice cutting experiment , some applied techniques , which include milling mode and direction , choosing cutter diameter and cutting start point setting , are developed . adopting the technology above , tens regular workpiece have been manufacturing . the two - year manufacture practice has confirmed the validity and feasibility of developed loxodrome coolant channel milling method . the developed technology is also worth to be referenced to other similar workpiece
将液体火箭发动机燃烧室的冷却通道设计为斜航线(等倾角螺旋线)槽形,可以大幅度改善燃烧室的冷却性能.斜航线冷却槽的槽宽尺寸较小而槽深尺寸较大,所以无法使用棒铣刀铣削、电化学等加工方式.针对这些特点,提出了五轴控制、四轴联动的数控片铣刀铣削加工方法.由于燃烧室外表面的母线轮廓复杂,手工编制数控加工程序难度大.为了解决数控加工程序的编制问题,研究了斜航线的数学模型,开发了自动编程软件系统.使用该系统,可以生成多种母线轮廓回转体外表面上的斜航线数控加工程序.燃烧室收敛-扩张段的母线斜率变化大,加工难度大,是斜航线冷却通道加工的最典型工件.经过理论分析和实际切削实验,研究了针对该类型工件的片铣刀直径选择、铣削方式和方向、刀具调整和起刀点的设置等多项实际的加工方案.采用上述的一系列技术,已经成功地加工了数十个合格工件.经过两年多的实际生产过程应用,验证了所开发的斜航线冷却通道加工方法的正确性和可行性.这些加工技术的研制成功,对其他相似类型零件的加工亦具有参考意义
