一.传动方案分析：
如图所示减速传动由带传动和单级圆柱齿轮传动组成，带传动置于高速级具有缓冲吸振能力和过载保护作用，带传动依靠摩擦力工作，有利于减少传动的结构尺寸，而圆柱齿轮传动布置在低速级，有利于发挥其过载能力大的优势
二.选择电动机：
（1）电动机的类型和结构形式，按工作要求和工作条件，选用一般用途的Y系列三相异步交流电动机。
（2）电动机容量：
①卷筒轴的输出功率Pw＝FV/1000=1350×1.6/1000=2.16 kw
②电动机输出功率Pd＝Pw/η
传动系统的总效率：η＝
式中……为从电动机至卷筒之间的各传动机构和轴承的效率。
由表查得V带传动＝0.96，滚动轴承＝0.99，圆柱齿轮传动
＝0.97，弹性连轴器＝0.99，卷筒轴滑动轴承＝0.96
于是η=0.96××0.97×0.99×0.96≈0.88
故:
Pd= Pw/η=2.16/0.88≈2.45 kw
③ 电动机额定功率由表取得=3 kw
（3）电动机的转速：由已知条件计算卷筒的转速
即:
=60×1000V/πD=60×1000×1.6/3.14×260=118 r/min
V带传动常用传动比范围=2-4，单级圆柱齿轮的传动比范围=2-4
于是转速可选范围为 ==118×（2～4）×（2～4）
=472～1888 r/min
可见同步转速为 500 r/min和2000 r/min的电动机均合适，为使传动装置的传动比较小，结构尺寸紧凑，这里选用同步转速为960 ×r/min的电动机
传动系统总传动比i= =≈2.04
根据V带传动的常用范围=2-4取=4
于是单级圆柱齿轮减速器传动比 ==≈2.04
把数字改一下就可以了
你按照指导 就计算被 要是不会 我帮你！！！
