Research on the Influencing Factors of Axial Preload Performance of Aluminum Alloy Thread

Wang, Xiaobin / Huang, Xiucheng / Zhang, Anwei / Liu, Yanbin / He, Guoxin / Yan, Xing

The model of thread connection preload is set up and the main factors affecting the performance of thread axial preload are analyzed theoretically. Based on the steel-aluminum connection structure, the test was carried out on the meshing length of aluminum thread, the friction of aluminum support surface, the friction of aluminum thread and the rotation speed by using the tightening system and ultrasonic preload measuring instrument. The results show that the stability of axial preload increases with the increase of the meshing length of aluminum thread. Increase the plain washer to effectively improve the friction state of the supporting surface, axial preload increased by nearly 40%; The friction state of thread was effectively improved by adding wire thread sleeve, and the axial preload was increased by nearly 46%. It is suggested that the proper increase of rotation speed is of certain significance to ensure the reliability of threaded connections.
