摘要
通过对方向机紧固螺栓表面处理工艺改进前和修正后各种状态下的参数对比,得出进一步提高拧紧后的轴向力安全系数的有效措施。通过对方向机支架螺纹孔强度校核,进一步确认方向机装配时的螺紧固螺栓轴向预紧力上限值。
The effective measures of further improve the safety coefficient of axial force after tightening are obtained by comparingthe parameters of the surface treatment process beforceand after the modification of the tightening bolt. By checking the strength of the threaded hole of the support bracket, the upper limit value of the axial pretightening force of the fastening bolt of thesteering wheel assembly is further confirmed.
