The main purpose is to transfer the motion of the high speed low torque device through relevant mechanical mechanism into a low speed high torque transmission. Main task is to design and complete the reducer gear in computing and assembly, the main task contain the choice of motor to the belt transmission design and calculation, to the design and calculation of gear and shaft design and calculation, finally according to the size of the selected gear and shaft in accordance with the relevant standard complete enclosure design and other related parts and components selection. The most important part of this design is the core of gear transmission part of the selection calculation and design calculation and check of each gear shaft is chosen in the design of helical gear, chose a helical gear is mainly in order to ensure the stability of the transmission and the use of the relationship between the two vice gear and reverse loading offset part of the axial force, residual axial force to offset by selecting the appropriate bearing, tapered roller bearings are the main choice in the design. Another window of this design is to use computer instead of traditional manual calculation, the main use is the Solidworks software, the software is mainly used to complete the 3D entity model, and then through the explosion view more clearly express of the structure principle to this device, and the use of the software of computing functions is to complete the checking calculation of gear and shaft.Keywords： gear； drive shaft； transmission ratio;；transmission efficiency兰州交通大学毕业设计III 620N.m 带式输送机传动装置的设计IV 目 录摘 要.IAbstract .II绪 论.- 2 -1电动机的选择.- 2 -2.传动比的分配及转动校核.- 2 -3.三角带的传动设计.- 2 -3.1 查取系数.- 2 -3.2 选取窄 V 带类型.- 2 -3.3 确定带轮基准直径.- 2 -3.4 确定窄 V 带的基准长度和传动中心距.- 2 -3.5 演算主动轮上的包角.- 2 -3.6 计算窄 V 带的根数.- 2 -3.7 计算预紧力.- 2 -3.8 计算作用在轴上的压轴力.- 2 -4.齿轮传动的设计.- 2 -4.1 高速级齿轮传动的设计.- 2 -4.1.1 按齿面接触疲劳强度进行设计.- 2 -4.1.2 再按齿根弯曲强度设计：.- 2 -4.1.3 几何尺寸计算：.- 2 -4.1.4 高速级齿轮传动的几何尺寸.- 2 -4.1.5 齿轮的结构设计.- 2 -4.1.6 Solidworks 进行齿轮的算例分析.- 2 -4.2 低速齿轮机构设计.
