双端面轴承研磨机上研磨盘的设计摘要研磨机是保证研磨加工的重要条件,目前国内使用研磨机的种类比较多,但是为了提高研磨加工效率,双面研磨机已经取代了传统的研磨机。
研磨机从加工精度上基本分为两种。
一种是加工不仅对精度要求较高并对面形精度也有所要求的工件。
另外一种是加工只要求表面粗糙度的零件,例如一些钨钢表带和纽扣等。
这种研磨机适合加工一些尺寸较小,而且数量较大的零件。
本文主要是合理的分析了双面研磨机的传动系统和研磨原理,根据研磨功率选择了合理的电动机,并设计了主要的传动零件和上研磨盘主轴。
为了使其具有足够的刚度、强度和稳定性,还对上研磨盘主轴上的主要零部件进行了强度校核、刚度校核以及精度分析。

From processing precision grinding machine on basic there are two kinds. One is processing not only to higher accuracy and precision also has requirements across the fractal work-piece. Another is the only requirement surface roughness processing parts, such as some tungsten steel strap and buttons, etc. This kind of grinding machine is suitable for processing some small in size, and greater number of parts.This paper is mainly reasonable analysis of two-sided grinding machine transmission system and grinding principle, according to the reasonable grinding power selection, and design the main motor on the transmission parts and grinding plate spindle. In order to make it has enough stiffness, strength and stability, also on the main axis grinding plate parts strength check, stiffness checking and precision analysis.KEY WORDS:Double-sided grinding, grinding,main axle目录前言 (1)第1章研磨机的发展历史 (3)研磨技术发展状况 (3)固着磨料高速研磨的研究现状 (4)研磨机的发展情况 (5)第2章研磨原理分析 (7)研磨机的工作原理 (7)研磨网纹分析 (9)研磨速度分析 (9)第3章研磨机传动系统分析 (11)选择电动机的选择 (11)3.1.1 选择电动机的类型 (11)3.1.2 选择电动机功率 (11)3.1.3 确定电动机的转速 (12)计算总传动比并分配各级传动比 (12)3.2.1 上主轴总传动比 (13)3.2.2 上主轴分配各级传动比 (13)3.2.3 下主轴总传动比 (13)3.2.4 下主轴分配各级传动比 (13)3.2.5 更换带轮后的总传动比 (13)计算立柱轴、上研磨盘主轴的运动和动力参数 (13)3.3.1 立柱轴、上研磨盘主轴的转速 (13)3.3.2 立柱轴、上研磨盘主轴的功率 (14)3.3.3 上研磨盘主轴的转矩 (14)与上研磨盘主轴联接得带传动设计 (14)3.4.1 确定计算功率P c (14)3.4.2 选取V带型号 (14)3.4.3 确定带轮基准直径 (14)3.4.4 确定中心距a和V带长度L d (14)3.4.5 校核小带轮包角α1 (15)3.4.6 .......................................................................... 确定V带的根数153.4.7 计算单根V带初拉力F0 (15)3.4.8 ...................................................................... 计算对轴的压力Q 153.4.9 带轮的结构设计 (15)第4章上研磨盘主轴设计 (16)主轴结构设计 (16)4.1.1 按许用扭转剪应力初估轴的直径 (16)4.1.2 主轴的尺寸确定 (17)轴的校核 (17)4.2.1 轴的强度校核 (17)4.2.2 主轴刚度校核 (20)4.2.3 滚动轴承校核 (21)4.2.4 机床主轴系统的精度分析 (22)结论 (25)谢辞 (26)参考文献 (27)前言研磨机是保证研磨加工的重要条件,因此人们专门研究了各种不同的研磨机。
