[摘要]
本设计是将一对圆锥齿轮传动与NGW行星机构串联，形成一个组合机构，用来传递两相交轴之间的运动和动力，并实现较大的传动比。对齿轮与中心轮组合的受力状况分析时，应引入不均载系数根据传动，工作扭矩，载荷，根据级数转速要求计算出齿轮的齿数，模数，分度圆直径，计算出传动齿的齿厚，齿面硬度，选择齿形，根据上述要求选定达到此要求的材料，并且做出经济效益最好的选择，再根据此材料的弹性影响系数，各传动齿轮接触疲劳强度极限，再对材料的选择正确与否做出校核，并且要满足减速器的使用寿命要求，根据载荷和传动扭矩计算传动主轴的直径及定位，计算中心距，确定行星轮系的周转圆半径及方向，并指定轮系的旋转方向，得到各项数据后，依据设计要求结构大小，确定各部件相对位置，进入外箱体的设计，秉承体积最小，拆装方便的原则，定好主轴位置，窥视孔，润滑口在箱体上的位置，便于维修判断。除齿轮以外，对于承受工作载荷的其他零部件如轴、键、轴承等、也进行了设计校核。减速器箱体采用法兰式结构，用以满足工作环境的安装条件。减速器高速级为圆锥齿轮传动，以实现换向。由于功率、传动比较大，将这对圆锥齿轮设计为斜齿圆锥齿轮。低速级采用NGW行星机构进一步增大传动比，NGW行星机构可以传递较大的功率以及实现较大的传动比，因此在设计中采用直齿圆柱齿轮。

[英 文]This design is a bevel gear transmission with NGW planetary bodies in series, forming a combination of institutions, to transfer the two-axis intersection between the movement and momentum and to achieve greater transmission ratio. Gear and centre round the composition of the force analysis of the situation, should be introduced under the uneven transmission coefficient, the torque, load, in accordance with the requirements in order to speed the gear teeth, module, the circle diameter, calculated Drive Tooth tooth thick, tooth surface hardness, select profile, in accordance with the requirements of the selected material to this request, and make the best choice for cost-effective, then this material under the impact of the flexibility factor, the transmission gear contact fatigue limit , And the choice of materials to check whether or not correct, and to meet the requirements of the life of reducer, according to load and transmission torque spindle drive calculated the diameter and location, from the ICC to identify planets revolving round the circle of radius And direction, and specify the round of the direction of rotation, get the data, based on the design requirements of size, determine the relative position of components into the box, the design is home to the smallest, to facilitate entry to the principle of the spindle good location, Peep hole, I lubrication in the box on the location, ease of main In addition to gear, the work load of other bear parts such as the axis, keys, the bearings, also had a design Reducer a flange-box structure to meet the conditions for the installation of the working environment.for high-speed cone gear trans mission in order to achieve commutation. As power, drive more, on this bevel gear designed to ramp bevel gear. Low level used to further increase NGW planetary transmission ratio, NGW planetary bodies can convey more power and the realization of the larger transmission ratio, used in the design of the spur gear.
