摘　　要：为了解决循环球变比转向器变比齿轮齿廓设计问题,提出一种数字设计方法;该方法在CATIA建模软件中,基于变传动比运动规律建立布尔减运算宏程序,模拟变比齿轮齿廓包络面范成加工过程,生成变比齿轮三维模型;对齿廓曲面进行修补,完成变比齿轮副的虚拟装配后,采用ADAMS软件对建立的变比齿轮齿条副进行运动仿真分析,将仿真得到的传动比曲线与设计用曲线进行对比分析,验证了该方法的有效性。In order to solve the design problem of variable ratio tooth profile of gear for the recirculating ball variable ratio steering,a digital design method is put forward,the Boolean reduction operation macro program is established based on variable ratio movement rule and the envelope surface generation machining processes of variable ratio tooth profile of gear is simulated in CATIA software,and the three dimensional model of variable ratio gear is generated. The tooth surface is repaired and the virtual assembly of variable ratio gear is completed,then the kinematics simulation analysis of variable- ratio rack and pinion meshing pair is carried out by using ADAMS software,the curve of simulation is analyzed and compared with the curve of designing,the effectiveness of the method is validated.
