随着现代工业的发展，电动滚筒作为主动辊子已经广泛的应用于各种生产线中，电动滚筒的优点也不断的凸现出来。由于电动滚筒具有结构紧凑、传动效率高、噪声低、使用寿命长、运转平稳、工作可靠、密封性好、占用空间小、安装维修方便等优点，并且适合各种恶劣的环境条件下工作。电动滚筒的设计制造技术也在不断的提高，制造的材料也在不断的改善，高新技术不断的引入，电动滚筒的应用范围必将越来越广泛，电动滚筒在国民经济中的作用将更大。
本次设计的油冷式电动滚筒是带式输送机的驱动装置，驱动电机和传动机构均置于滚筒体内，依靠油液冷却，电动滚筒要实现把电动机的旋转运动传递给滚筒，使滚筒也转动才能驱动胶带运行。本次毕业设计是围绕油冷式电动滚筒的传动部分进行设计，设计的主要内容有：传动方案设计，分配传动比，零部件设计（包括材料选择、结构设计和强度计算），标准件选择，绘制总装配图和零件图及编写说明书。

With the development of modern industry，electric roller as active roller has been widely used in various production lines，and the advantages of electric roller are constantly highlighted. Because the electric roller has the advantages of compact structure，high transmission efficiency，low noise，long service life，stable operation，reliable work，good sealing，small occupied space，convenient installation and maintenance，and is suitable for working under various harsh environmental conditions. The design and manufacture technology of electric drum is improving constantly，the material of manufacture is improving constantly，the application range of electric drum will be more and more extensive，the work of electric drum in national economy
The designed oil-cooled electric drum is the driving device of the belt conveyor，the driving motor and the transmission mechanism are placed in the drum body，relying on the oil cooling，the electric drum must realize the rotating motion of the motor to the drum，so that the drum can also rotate to drive the tape operation. This graduation design is around the transmission part of the oil-cooled electric drum design，the main contents of the design are: transmission scheme design，distribution transmission ratio，parts design (including material selection，structural design and strength calculation)，standard parts selection，drawing general assembly drawing and part drawing and writing instructions.
