螺纹联近及螺旋传秘在机械设备中应用极广,其螺纹间载荷分布不均匀的规律早由茹柯夫斯基得出。螺纹间载荷分布的不均匀性,对螺纹联接和螺旋传动装置带来不利影响,导致螺纹磨损不均匀,进而引起破坏,材料承载能力亦未能充分发挥,对于承受重载的轧钢机、压力机的调整螺母和传动螺母,分析它的螺纹间载荷分布规律,影响因素,进而作出更合理结构设计,是有实践意义的。这里仅依据见到的几篇资料所介绍的分析螺纹间载荷分布规律的方法,综合作的一篇研究报告,说明在一般受载情形下螺纹间载荷分布规律如何分析得到,并具体应用来试分析教学中设计的起重螺旋,它的螺纹间载荷分布规律,至于深入分析其影响因素,作出合 The close proximity of the thread and the transmission of the helical thread are very widely used in machinery and equipment. The uneven distribution of the load between the threads leads to Rukowski’s derivation. Inhomogeneous load distribution between the threads has an adverse effect on the screw connection and the screw drive, resulting in uneven wear on the threads, which in turn causes damage and the material carrying capacity has not been fully utilized. For rolling mills under heavy load, Of the adjusting nut and the drive nut, analyze its load distribution between the thread rules, the influencing factors, and then make a more reasonable structural design, it is of practical significance. Here only based on the information presented in the introduction of the analysis of load distribution between the threads of the method, a comprehensive study made a description of the general load situation under the load distribution between the threads how to analyze the specific application to test Analysis of teaching design of the lifting screw, its load distribution between the threads of the law, as for its in-depth analysis of the influencing factors to make
