6、、终身免维护等特点。因为这些特点，行星减速机多数是安装在步进电机和伺服电机上，用来降低转速，提升扭矩，匹配惯量。  行星减速机额定输入转速最高可达到18000rpm(与减速机本身大小有关，减速机越大，额定输入转速越小)以上，工业级行星减速机输出扭矩一般不超过2000Nm，特制超大扭矩行星减速机可做到10000Nm以上。工作温度一般在-25℃到100℃左右，通过改变润滑脂可改变其工作温度。　　2齿轮减速器部件的结构设计2.1引言齿轮减速器26山东建筑大学课程设计说明书是利用各级齿轮传动来达到降速的目的.减速器就是由各级齿轮副组成的.比如

7、用小齿轮带动大齿轮就能达到一定的减速的目的,再采用多级这样的结构,就可以大大降低转速了.齿轮减速机一般用于低转速大扭矩的传动设备，把电动机.内燃机或其它高速运转的动力通过减速机的输入轴上的齿数少的齿轮啮合输出轴上的大齿轮来达到减速的目的，普通的减速机也会有几对相同原理齿轮达到理想的减速效果，大小齿轮的齿数之比，就是传动比。2.2结构设计一、齿轮减速器输出轴、输入轴设计如下图：技术要求:1.尖角倒钝。2.线性尺寸的未注公差按GB/T1804-C。3.未注形位公差按GB/T1184-K。二、齿轮减速器的定位销设计如下图：技术要求:1.尖角
