摘　　要：汽车主减速器齿侧间隙调节是通过旋转主齿两端的花螺母进行调整的,然而目前的调整方法均是根据经验手动调节,不仅调节精度有限,而且效率低下。在结合实际生产经验,分析工艺要求后,提出一种自动化调整方案,并运用牛顿插值多项式,拟合调节花螺母与齿侧间隙间的关系函数。同时采用闭环控制实现间隙的有效测量和及时反馈,从而提高控制精度。实践证明:通过数据分析和现场实践,验证所提方案可靠有效,可以提高车间调节效率。The gear backlash of main gear box is adjusted by rotating knurled nuts w hich are located on the either side of the main gear. How ever,the current general adjustment method is adjusting manually from experience w hich usually caused low precision and efficiency. Based on the actual production experiences and analysis of process,an automotive adjustment solution is put forw ard. Then,New ton interpolation method is proposed as a curve fitting method w hich describes the functional relationship betw een adjusting knurled nut and gear backlash. And to improve control accuracy,the control system used closed-loop control to realize the efficiency of measurement and timely feedback. Through data analysis and field application,this system is proved to be reliable and efficient on improving adjustment efficiency.
