平动螺旋齿线圆柱齿轮凹凸齿面曲率半径调节方法与接触状态分析
Method of adjusting the radius of curvature of concave and convex flanks of translating spiral toothed line cylindrical gears and analysis of the contact state
摘要
Abstract
The main geometrical parameters of the translating spiral toothed line cylindrical gears were introduced,and its process-ing principle was explained—the big cutter disc rotates once,the blank rotates one tooth,so as to achieve the continuous sprea-ding processing of the full width.In order to improve the bearing capacity of the translating spiral toothed line cylindrical gear transmission system,the multi-right-angled trapezoidal tool single-sided tooth cutting method was put forward to carry on the tooth surface modification.Through the staggered installation of the tool,the concave tooth surface radius of curvature and convex tooth surface radius difference of zero was achieved.According to the processing principle,the concave and convex tooth surface equa-tions of the modified translating spiral toothed line cylindrical gears were deduced,and through the simulation of the process of the concave and convex tooth surface shaping process was demonstrated.The unmodified translating spiral toothed line cylindrical gears were compared with the modified translating spiral toothed line cylindrical gears by finite element static analysis.The results show that the modified translating spiral toothed line cylindrical gears have longer tooth contact lines,lower tooth contact stresses and better load carrying capacity.The results of the study will provide a theoretical basis for the design of high-quality translating spiral toothed line cylindrical gears and gear modification.关键词
