摘要
目前市场上,绝大部分常规电风扇的摇头机构都采用双摇杆机构,风扇在摇头过程中,驱动电机输出扭矩的轴受到交变力的作用,驱动电机和传动机构长期受到交变力,相关轴套易磨损破坏等,导致驱动电机末级齿轮与次末级齿轮间隙进一步加大,易产生齿轮噪音,内部各零件配合进一步变大,使用寿命减短。基于matlab和ansys通过机械原理和有限元受力分析,对机构的设计和受力分析研究,设计更合理的双摇杆机构,优化驱动电机所受交变力峰值和突变,改善齿轮噪音,确保机构运行稳定性,延长驱动电机使用寿命,能有效提高产品可靠性。
At present,most of the conventional electric fan shaking head mechanism adopts double rocker mechanism,fan in the shaking process,drive motor output torque shaft by the action of alternating force,drive motor and transmission mechanism long-term alternating force,related shaft sleeve easy wear damage,etc.,resulting in the drive motor final gear and the secondary gear clearance further increased,easy to produce gear noise,internal parts further enlarged,service life shortened.Based on MATLAB and ANSYS through mechanical principle and finite element force analysis,the design and force analysis of the mechanism are studied,and a more reasonable double rocker mechanism is designed,the peak and sudden change of alternating force subject to the drive motor are optimized,the gear noise is improved,the operation stability of the mechanism is ensured,the service life of the drive motor is extended,and the product reliability can be effectively improved.
