【摘要】：针对螺纹联接件因材料变形造成受力不均的现象,设计了一种变螺距螺母,用螺距的变化量抵消螺纹联接件的受力变形,进而改善受力情况。根据螺纹联接的载荷分布规律,计算在预紧力作用下的变形量,根据每一圈螺纹的变形量设计螺母螺距的变化量。利用Solidworks软件进行三维建模,Workbench软件对模型的受力情况进行仿真,根据结果验证此方法是否可行。
[Abstract]:A variable pitch nut is designed to counteract the stress distortion of threaded joint due to the deformation of screw thread, and then to improve the stress situation. According to the load distribution law of thread connection, the deformation amount under the action of pretightening force is calculated, and the variation of nut pitch is designed according to the deformation quantity of each ring thread. The model is simulated by Solidworks software and verified whether the method is feasible or not.
