摘要
本次论文的题目是“带式输送机传动装置的设计计算”。设计的主要目的在于将高转速小扭矩的运动装置通过相关机械机构转换为低转速大扭矩的传动装置。主要任务是进行结构设计并完成减速机中传动装置的计算以及装配,设计主要从电动机的选择到带传动的设计计算,再到齿轮的设计计算以及轴的设计计算,最后根据所选齿轮以及轴的尺寸根据相关标准完成箱体的设计以及其它相关零部件的选择。本次设计最主要的也是最核心的部分是齿轮传动部分的选择计算以及各齿轮轴的设计计算与校核,在这次设计中选用的是斜齿轮,之所以选用斜齿轮主要是为了保证传动的稳定性以及利用两副齿轮正反装的关系相互抵消部分轴向力,剩余轴向力通过选择合适轴承来抵消,在这次设计中主要选用的是圆锥滚子轴承。此次设计的另一亮点在于利用计算机代替传统的人工计算,主要用到的软件是Solidworks,该软件的主要用来完成三维实体的造型,然后通过爆炸视图更加清晰的表达该装置的结构原理,以及利用该软件的运算功能完成齿轮和轴的校核计算。

Abstract
This paper on the topic of " the design and calculation of belt conveyor drive". 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 plete the reducer gear puting 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 plete enclosure design and other related parts ponents 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 puter instead of traditional manual calculation, the main use is the Solidworks software, the software is mainly used plete the 3D entity model, and t
