结果表明：采用双重保险工艺处理的主动圆锥齿轮尾部螺纹硬度完全可以达到产品技术要求，质量稳定可靠，但成本较高；采用感应退火工艺，尾部螺纹硬度可以达到技术要求，其特点是节能、生产效率高，但需要定期对尾部螺纹进行力学性能检测。

5A kind of stress-relief groove of box thread joint has been developped. Finite Element models of several thread joints have been established by ABAQUS. The Morrow Strain-life Model is used to evaluate the fatigue life of 3 kinds of connections with different stress-relieaf grooves of box. The results show that the fatigue life of box with stress-relief groove developed in the paper is the longest.

为了定量评价几种螺纹接头的疲劳寿命大小，采用Morrow应变周期模型结合有限元分析结果计算3种具有内螺纹应力减轻槽母扣的疲劳寿命，计算结果表明本文设计的内螺纹应力减轻槽能显著延长母扣的疲劳寿命。

The two threading lines could process round thread, buttress thread, premium connection, and so on.

两条车丝线可加工圆螺纹、偏梯形螺纹、特殊螺纹等。

The article indicates the characteristics of buttress thread compared with round thread and analyzes the defect caused by materials size of API and 5CT plane tube.

文章通过分析指出，偏梯形螺纹有比圆螺纹更具优势的特点，也因此在使用符合API 5CT要求的套管原料进行生产时，由于平端套管原料管子尺寸精度原因而更易产生缺陷，通过理论计算和现场实测，提出了合适的偏差范围。

While making-up with casing tongs, the recommended torque for both standard round thread casing and buttress thread casing is given in Annex A and Annex B respectively.
