结合齿轮啮合原理,推导出塑料斜齿轮与钢制蜗杆传动副的啮合方程式.基于MSC.Patran/Nastran建立塑料斜齿轮和钢制蜗杆传动的本体温度场,并对啮合传动副进行有限元结构分析,得到此传动机构热平衡过程中载荷、本体温度和环境温度之间的内在联系.并通过赫兹接触理论验证了有限元分析的正确性.结果表明:在该传动过程中,热源从啮合齿面逐渐扩散到轮齿端面和非工作齿面上,热平衡时啮合齿面上轮齿中部靠近分度圆处温度最高,而轮齿端部温度最低.
結閤齒輪齧閤原理,推導齣塑料斜齒輪與鋼製蝸桿傳動副的齧閤方程式.基于MSC.Patran/Nastran建立塑料斜齒輪和鋼製蝸桿傳動的本體溫度場,併對齧閤傳動副進行有限元結構分析,得到此傳動機構熱平衡過程中載荷、本體溫度和環境溫度之間的內在聯繫.併通過赫玆接觸理論驗證瞭有限元分析的正確性.結果錶明:在該傳動過程中,熱源從齧閤齒麵逐漸擴散到輪齒耑麵和非工作齒麵上,熱平衡時齧閤齒麵上輪齒中部靠近分度圓處溫度最高,而輪齒耑部溫度最低.

According to the gear engagement theory,the gearing equation between plastic helical gear and steel worm was carried out.The bulk temperature field of the gear pair was established based on MSC.Patran/Nastran.An analysis was wade by finite element method(FEM) and the relationship between load,buck temperature and environmental temperature in the process of heat balance was obtained.Based on Hertz contact theory,the finite element analysis result was verified.Study results show that the heat transfers from the meshing gear tooth surface to face and non-working tooth surface gradually;the highest temperature is around the central pitch circle of the meshing gear tooth and the lowest on the end gear.
