【摘要】：針對某微車高速空擋滑行工況下主減速器振動異響大的問題,以主減速器準(zhǔn)雙曲面齒輪壓力角為研究對象。建立了齒輪系統(tǒng)扭轉(zhuǎn)振動動力學(xué)模型,改變UG模型中輪齒兩側(cè)壓力角,導(dǎo)入到ADAMS后對比分析該工況下不同壓力角時齒輪系統(tǒng)的動態(tài)特性,得出被動輪輪齒凸面壓力角減小1°、同時凹面壓力角增大1°時可改善主減速器齒輪系統(tǒng)嚙合振動性能。最后采用試驗驗證了仿真分析的正確性,可應(yīng)用于主減速器齒輪的設(shè)計和制造。
[Abstract]:Aiming at the problem of large vibration abnormal noise of the main reducer under the condition of high speed neutral sliding of a micro car, the hypoid gear pressure angle of the main reducer is taken as the research object. The dynamic model of torsional vibration of gear system is established. The pressure angle of both sides of gear teeth is changed in UG model. After introduced into ADAMS, the dynamic characteristics of gear system under different pressure angles are compared and analyzed. It is concluded that the meshing vibration performance of the main reducer gear system can be improved by reducing the pressure angle of the convex face of the passive gear teeth by 1 擄and increasing the concave pressure angle by 1 擄. Finally, the correctness of simulation analysis is verified by experiments, which can be used in the design and manufacture of main reducer gear.
