简易地坑式龙门刨床变速箱设计 专业班级： 11机 制 1班 学生姓名： 指导教师： 职称： 摘要 ： 本文主要阐述了简易地坑式龙门刨床变速箱设计过程。 变速箱一般是由齿轮、轴、轴承及箱体 等 组成，用于原动机和工作机或执行结构之间，起匹配转速和传递转矩的作用，在现在机械中应用极为广泛。 变速箱的结构形式各种各样，但其设计方法和过程具有通用性和普遍性。该变速箱来源于生产实际，传动功率较大，属于专用部件。本文在采用传统设计方法的同时，也考虑了一些最新的设计方法。本文主要 由以下部分组成： 变速箱的设计， 包括齿轮、轴、键、花键、轴承及箱体的设计、计算与校核。 相比传统设计，本设计主要有以下特点： 1.以最高转 速和最大输出扭矩为要求，平行计算，并将计算结果加以比较，以安全 可靠为原则选择参数； 2.采用单输入结构，两种转速输出，并由拔叉机构控制其输出 ； 3.箱体采用焊接结构 。 关键词 ： 变速箱 单输入 两种转速输出 焊接结构 ntsThe design of transmission gear box in simply and dyadic planer machine Abstract： This thesis mainly elaborated the design of transmission gear box in simply and dyadic planer machine process. Transmission gear box generally constitutes of wheel gear, stalk, bearings and box body , the box body used for prime mover and work machine, transmission gear box have already and used for among the speed and deliver the turn jug, its application is extremely extensive in the machine in nowadays. The structure form of the transmission gear box is various each kind, but its design method and process have used generally and catholicity. The transmission gear box comes from produce physically and move power bigly, belongs to an appropriation parts. This thesis also considered some latest design methods at the time of adopting a tradition design a method. This thesis mainly constitutes of the following parts: The design of transmission gear box, calculation and school which include wheel gear, stalk, key, the flower key, bearings and box body check. Compare a tradition design; this design mainly includes a following characteristic: 1. With highest speed with the biggest exportation turn Jud for request, parallelism calculation, and take into calculation as a result compare, with safety, credibility as principle to choice parameter; 2 .Used one input structure, 2 kinds of speed as output, and from pull out fork organization to control its exportation. 3. The body of transmission gear box used
