【摘要】 汽车门锁传动机构中的齿轮是自吸合汽车门锁系统中容易失效的部件,对汽车的行驶安全起着重要影响。近年来,在汽车行业的电装产品中,塑料齿轮逐渐替代一些金属齿轮。为了保证汽车门锁传动机构中的塑料齿轮能够可靠稳定的工作,满足其工作强度要求,本文介绍了一种基于尼曼温特尔法与刘易斯疲劳强度理论的塑料齿轮强度计算方法,提出了提高齿轮强度,优化塑料齿轮传动性能的设计方法。经过优化设计后,塑料齿轮性能得到提升并能够正常工作,证明了齿轮优化设计是成功的。更多还原

【Abstract】 The gear in the car door lock transmission mechanism is an important component,which is easy to fail in the power cinching car door lock system,and plays an important role in the driving safety of the car. In recent years,some metal gears have been gradually replaced with plastic gears in the electrical products of the automotive industry. In order to ensure the reliable and stable operation of plastic gear and meet the requirements of working strength,the strength calculation method based on the Niemann Winter method and Lewis fatigue strength theory for plastic gears is introduced in the paper. And the design methods to improve the plastic gear strength and optimize the plastic gear transmission performance are proposed. The designed plastic gears can work normally,and it is proved that the design and optimization for plastic gears are successful.更多还原
