1) even number of threads
偶数螺纹
2) even thread
偶螺纹
3) thread parameter
螺纹参数
1.
In order to real-timely and accurately measure thread parameters such as thread angle(tooth-type half-angle),screw-pitch,lead,thread height,major diameter,minor diameter,pitch diameter,helix angle etc,and enhance the measuring accuracy,a non-contact thread parameter measuring system based on an array CCD was designed and achieved.
为实时准确地对螺纹的牙型角(牙型半角)、螺距、导程、螺纹高度、大径、小径、中径、螺纹升角等参数进行测量,并提高测量精度,设计并实现了基于面阵CCD的螺纹参数非接触测量系统。
2.
An oil pipe thread parameter automatic measuring instrument based on machine vision,which is designed after the concept of optical-mechanical-electrical integration,is developed and introduced.
文中采用光机电一体化的思想,将光源、CCD、计算机等有机结合,开发了一种基于面阵CCD技术的石油管螺纹参数智能化测量系统。
3.
Then,the equations between sealing performance and big omega connection thread parameters were obtained.
以德国非API标准的Big Omega特殊螺纹接头作为研究对象,应用有限元软件ANSYS建立计算力学模型,模拟套管柱接头行为,通过改变螺纹参数(高度、锥度等),计算得出各扣牙相应的最大法向接触应力与最大接头Mises应力。
4) the modular system screw
模数螺纹
1.
It is used to cut some type screws, such as the metric system screw, the modular system screw, and so on, when their transfer ratio of multiple structure equals one.
以C6 2 0 1型车床为例,对卧式车床摆移齿轮进给箱传动系统研究后,发现了一条新的传动路线,可以减少i倍 =1时,车削公制螺纹、模数螺纹、以及大导程螺纹传动链中传动齿轮 6个,使传动路线大大缩短,可较大地提高传动精度和被加工螺纹精度。
5) number of starts of thread
螺纹头数
6) number of starts
螺纹扣数
