1、洛阳理工学院毕业设计(论文)卧式钢筋切断机摘要本课题设计建筑上用的卧式钢筋切断机的工作原理是:采用电动机经一级三角带传动和二级齿轮传动减速后,带动曲轴旋转,曲轴推动连杆使滑块和动刀片在机座的滑道中作往复直线运动,使活动刀片和固定刀片相错而切断钢筋。根据电机的工作环境选择电动机类型,采用卧式安装,防护式电机,鼠笼式三相异步电动机。选择三级减速,先是一级带减速,再两级齿轮减速。一级带传动,它具有缓冲、吸振、运行平稳、噪声小、和过载保护等优点,并安装张紧轮。两级齿轮减速,齿轮传动可用来传递空间任意两轴间的运动和动力,并具有功率范围大,传动效率高,传动比准确,使用寿命长,
2、工作安全可靠等特点。动力由电动机输出,通过减速系统传动,把动力输入到执行机构。由于传动系统作的是回转运动,而钢筋切断机的执行机构需要的直线往复运动,为了实现这种转换,可以采用曲柄滑块机构,盘行凸轮移动滚子从动件机构,齿轮齿条机构。本课题采用曲柄滑块机构作为本机械的执行机构 。关键词:钢筋切断机,曲柄滑块机构,齿轮齿条机构4洛阳理工学院毕业设计(论文)ACCITECTURALLIETYPESTEELCUTTINGMACHINESABSTRACTThisarticleintroducesakindofarchitecturallietypesteelcuttingma
