| 1. | Research on the techniques and their realization to improve the tri - cone rock bits ' life span 与牙轮钻寿命相关的若干技术及其实现的研究 |
| 2. | 7 . assemble inserts and cones respectively , and prepare for calculating 3d engaging distance of tri - cone rock bit 对牙轮和牙齿分别进行了装配,为三维啮合间隙计算做了充分准备。 |
| 3. | Tri - cone rock bit is the important tool in oil drilling , so its capability and quantity affect the speed and cost of oil drilling greatly 三牙轮钻头是石油钻井的重要工具,其性能和质量对钻井速度和成本影响很大。 |
| 4. | The structure of tri - cone rock bit is complicated . as the cutting structure touch the stratum directly , it affects the process of breaking rock and the performance of tri - cone rock bit 三牙轮钻头结构复杂,其中齿面结构直接与地层接触,对于岩石破碎过程和钻头工作性能的影响最大。 |
| 5. | 3 . solve the key problem during the 2d engaging design of the tri - cone rock bit . if you move or rotate any insert with mouse , the other two inserts in the same cycle change same positions 解决了三牙轮钻头二维啮合设计中的关键技术?联动布齿,通过鼠标移动和旋转任意一个牙齿,同一齿圈上的其它两个牙齿做相同的位置变动。 |
| 6. | Application the system to the design of tri - cone rock bit , will shorten the developing cycle of new products , and improve the design quality , and increase the technology innovation of enterprise and enhance the market competition 通过本软件的应用,可以缩短三牙轮钻头的设计周期,提高产品的设计质量,提高企业的技术创新能力和市场竞争能力。 |
| 7. | It is not reported that any software has been developed on the engaging design of tri - cone rock bit with pro / e workbench in china and other countries . therefore , this software is developed with pro / e2000i on 2d engaging design and 3d models design of cones and inserts and their assembly , and the program languages are pro / toolkit and delphi 在pro e环境下开发三牙轮钻头的啮合设计在国内外还未见到,因而本系统选择pro e为二次开发平台,采用参数化设计思想,利用pro toolkit和delphi联合编程,适合三牙轮钻头二维啮合设计、牙轮牙齿三维实体造型和装配。 |
