6、.2.7生产规模中型机械厂，小批量生产。1.3主要技术数据1.3.1输送带工作拉力F=3.6kN；1.3.2输送带工作速度v=0.55m/s；1.3.3滚筒直径D=380mm；1.3.4电机转速n=1500r/min.1.4设计工作及内容：1.4.1传动方案的确定；1.4.2电机选型；1.4.3传动装置的运动和动力参数计算；1.4.4带传动设计；1.4.5减速器设计(51齿轮、轴的设计计算、轴承、连接件、润滑和密封方式选择，机体结构及其附件的设计)；1.4.6联轴器选型设计；1.4.7绘制减速器装配图和零件

7、工作图；1.4.8编写设计说明书；1.4.9设计答辩。1.5传动装置总体设计1.5.1组成：传动装置由电机、减速器、工作机组成。1.5.2特点：齿轮相对于轴承不对称分布，故沿轴向载荷分布不均匀，要求轴有较大的刚度。1.5.3确定传动方案：考虑到电机转速高，传动功率大，将V带设置在高速级。图1-1传动装置总体设计图1.6设计任务：应完成：①减速器装配图一张；②齿轮、轴的零件图2张；③设计计算说明书一份。第一章、传动方案分析已知:已知输送带工作速度为0.55m/s，滚筒直径为380mm,输送带工作拉力为3.6k

8、N。连续单向运转，工作时载荷较平稳有轻微振动，使用寿命为8年。51该传送机有轻微振动，由于V带有缓冲吸振能力，采用V带传动能减小振动带来的影响，并且该工作机属于小功率、载荷变化不大，可以采用V带这种简单的结构，并且价格便宜，标准化程度高，大幅度降低了成本。减速器部分用两级圆柱齿轮减速器。第一章、电机的选择3.1传动装置的总效率＝=0.85为V带的效率,为四对滚动轴承的效率，为每对齿轮啮合的效率，为联轴器的效率，为
