摘 要
电动滚轮减速器作为一种新型的驱动装置,已经广泛的应用于各行各业作为输送机械等设备的驱动装置。
电动滚轮减速器的主要优点是结构紧凑、传动效率高、噪声低、使用寿命长、运转平稳、工作可靠、密封性能好、占据空间小、安装维修方便,适合在各种恶劣的环境条件下工作。它将电动机和减速器共同置于滚筒体内部,从而提高了滚筒传动的效率。
在滚筒体设计中我选用了薄形筒体的经验公式,在传动设计中我选择的是NGW型行星齿轮传动,第一级采用内齿圈固定,行星架输出,第二级采用行星架固定,内齿圈输出。行星齿轮传动中行星轮可以分担负荷,传动结构更为紧凑。为了充分发挥行星齿轮传动的优点,采用了均载机构使各个行星齿轮都能够分担载荷,以补偿不可避免的误差,降低了不均匀系数,提高承载能力。

Abstract
As a new type of driving devices, Electric Roller has been widely applied as transportation equipment such as mechanical devices driven to the various sectors.
The main advantage of the roller is Cohesive, efficient transmission and low noise, long life and smooth operation, working, reliable, good performance sealed, a small space, installation maintenance convenience, and Suitable for the harsh environment in a variety of conditions. Reducer common electric motors and machines will be placed within the body, Thus enhancing the efficiency of roller mill.
In roller I choose a thin-shaped design experience cylinder formula, in transmission design I chose NGW-planetary gear transmission. First-class I use of fixed gear, and the Planet-export. Second-class I Using planetary fixed, and of gear export. Planetary gear transmission can share the load of planetary round, so transmission structure more compact. To bring into full play the advantages of planetary gear transmission and are used to set the various agencies can share the load planetary gear to compensate the inevitable errors and reducing uneven factor increase carrying capacity together.
Keywords: Electric Roller, Planetary gear transmission, Velocity ratio
