毕业论文中文摘要毕业论文外文摘要手推式剪草机的设计摘要 为了更好的适应人们的需求，通过仔细分析对比，改进了原有的切割形式。本设计中，手推式剪草机主要利用滚动的轮子带动机械运动。手推式剪草机结构简单，连接平稳，噪音极小，并且操作十分容易，既给使用人带来方便，也给周围的人带来舒适，安静的环境。能更好的满足客户的需要。本文基于机械设计和相关的理论研究，设计了手推式剪草机的传动部分，并且用凸轮和推杆的设计方法设计了端面齿轮和拨杆。此次设计的手推式剪草机的左右两侧对称，其特点是结构简单,受力均匀,运行平稳,摩擦阻力小，弯曲性能好,不易出现堵塞，具有很强的适应性。关键词 草坪修剪机 剪草 减速器 手推 凸轮组件 改进设计The design of hand pushing lawn cropperAbstract In order to adapt to the demands of the people, through analysis and comparison, I improve the original form of cutting. This design, hand thrust lawnmowers mainly use the scroll wheel drive mechanical motion. Hand thrust lawnmowers has simple structure, low noise, smooth operation, and very easy to use, bring convenience to people around, comfortable and quiet environment. To better meet the needs of the client. Based on the mechanical design and relevant theory research and design, hand thrust lawnmowers transmission part, and the design method of CAM and putting the end gear and dial design. The design of the hand thrust about lawnmowers, its characteristic is the symmetry of simple structure, smooth operation, small bending, friction, good performance, do not appear to jam, strong adaptability.Keywords The lawn cropper Cu
