汽车空调箱风门驱动机构的设计研究
摘要
运用机械机构设计原理和CATIA软件的运动学模块,创建汽车空调箱风门驱动机构的运动仿真。使用CATIA的law特性驱动风门和凸轮,生成曲柄销轴在凸轮上的运动轨迹的方法来设计凸轮。对其轨迹进行压力角的分析与调整,减小压力角来减小机构的扭矩。对机构零件的配合间隙和材料特性的选用,来减小机构的噪音。通过凸轮槽的设计以及机构零件的配合间隙和材料的选用,为运动机构设计及改进提供理论依据和设计经验。
Based on the design principle of mechanical mechanism and the kinematics module of CATIA software, the motion simulation of air door driving mechanism of automobile air conditioning box is established. The cam is designed by using the law characteristics of CATIA to drive the valve and cam to generate the trajectory of the crank pin shaft on the cam. The pressure angle is analyzed and adjusted to reduce the pressure angle to reduce the torque of the mechanism. The selection of fit clearance and material characteristics of mechanism parts to reduce the noise of the mechanism. Through the design of cam groove and the selection of fit clearance and material of mechanism parts, the theoretical basis and design experience are provided for the design and improvement of kinematic mechanism.
