  五、V带传动规划·······································8

  六、齿轮传动规划·································11

  输送机传动装置中的一级直齿减速器。运动简图作业条件冲击载荷，单向传动，室内作业。三班制，运用5年，作业机速度差错±5%。

  一、课程规划使命要求····························3

  二、电动机的挑选·································4

  依据电动机所需的功率，并考虑电动机转速越高，总传动比越大，减速器的尺度相应越大，所以选用Y132M2-6.额外功率5.5kw，满载转速960r/min，额外转矩2.0N/m，最大转矩2.2N/m。
