46、传动和行星传动之分。调度绞车的传动齿轮既有内啮合圆柱齿轮传动，又有行星传动，所以调度绞车又称内齿轮行星传动绞车。 调度绞车常用型号主要有JD0.4(JD4.5)、JD1（JD）11.4）、JD1.（JD22）、JD2（JD25）、JD3（JD40）等。 下面以JD3（即JD40）型调度绞车为例介绍调度绞车的组成及传动原理。 （一）JD3型调度绞车的组成 JD3型调度绞车的主要组成部分为滚筒、制动装置机座和电动机。绞车滚筒由铸钢制成，其主要功能是缠绕钢丝绳牵引负荷。滚筒内和大内齿轮下装有减速齿轮。 绞车上共装有两组带式闸，即制动闸2，工作闸3。电动机一侧的制动闸2用来制动滚筒，大内齿轮上的工作闸

47、3用于控制Z7组运转。 机座用铸铁制成，电动机轴承支架及闸带定位板等均用螺栓固定在机座上。电动机为专用隔爆三相笼型电动机。 （二）JD3型调度绞车的传动原理 该型绞车采用两级内啮合传动和一级行星轮传动。Z1/Z2和Z3/Z4为两级内啮合传动，Z5、Z6、Z7组成行星传动机构。 在电动机5轴头上安装着加长套的齿轮Z1，通过内齿轮Z2、齿轮Z3和内齿轮Z4，把运动传到齿轮Z5上，齿轮Z5是行星轮系的中央轮（或称太阳轮），再带动两个行星齿轮Z6和大内齿轮Z7。行星齿轮自由地装在2根与带动固定连接的轴上，大内齿轮Z7齿圈外部装有工作闸，用于控制绞车滚筒运转。 若将大内齿轮Z7上的工作闸3闸住，而将滚筒上的制动闸2松开，此时电动机转动由两级内啮轮传动到齿轮Z5、Z6和Z7。但由于Z7已被闸住，不能转动，所以齿轮Z6只能一方面绕自己的轴线自转，同时还要绕齿轮Z5的轴线（滚筒中心线）公转。从而带动与其相连的带动转动，此时Z6的运行方式很类似太阳系中的行星（如地球）的运动方式，齿轮Z6又称行星齿轮，其传动方式称为行星传动。 反之，若将大内齿轮Z7上的工作闸3松开，而将滚筒上的制动闸2闸住，因Z6与滚筒直接相连，只作自转，没有公转，从Z1到Z7的传动系统变为定轴轮系，齿轮Z7做空转。倒替松开
