摘     要
 齿轮泵的概念是很简单的，即它的最基本形式就是两个尺寸相同的齿轮在一个紧密配合的壳体内相互啮合旋转，这个壳体的内部类似“8”字形，两个齿轮装在里面，齿轮的外径及两侧与壳体紧密配合。来自于挤出机的物料在吸入口进入两个齿轮中间，并充满这一空间，随着齿的旋转沿壳体运动，最后在两齿啮合时排出。
 本文阐述了本次课题的选题背景意义；分析了全不锈钢齿轮泵的工作原理，主要结构和要求实现的功能任务；研究了齿轮泵的齿轮传动及流量，各零部件的设计。
 本次课题的重点是设计计算。考虑泵的工作环境，确定泵的材料为1Cr18Ni9Ti；按给定的参数，进行了水力计算，得出泵的输入功率和转矩；对齿轮计算校核，得出齿轮的基本参数；对轴计算校核，并选取轴周向定位零件，包括滑动轴承、机械油封和联轴器；选取精度尺寸，包括配合尺寸公差、表面粗糙度和形位公差；绘制了装配图和零件图。

KCB-33.3 stainless steel gear pump system design

Abstract
 The concept of gear pump is very simple, the Basic form is two gears which have same size rotate with each other in the close engagement  shell,the shell inside is similar to a shape of “8”. Two gears mounted inside ,diameter and the both sides of the gear work closely with the shell .Material gose into the middle of two gears through the intake,then filled the space,with the gear rotary moving along the shell,finally discharged when two gears mesh.
 This paper elaborate the background and significance of my issue; analysis the principl of stainless steel gear pump, the main structure and functions required; research transmission , flow and parts design of this gear pump.
 The emphasis of this issue is design. Determine the material as 1Cr18Ni9Ti because of situations the pump work at; According to the given parameters, carried out hydraulic calculations on the input pump power and torque; Designed and checked the gear to obtain the basic gear parameters; Designed and checked arbor,And selected the parts which contact to the arbor, including bearings, mechanical seals and couplings;Selected precision measurements, including the dimensional tolerances, surface roughness and geometrical tolerance; Drawed a assembly and parts drawings.
 the task of The design is to complete one manual of KCB-33.3 stainless steel gear pump system design, drawings, article Translations contain 18000 characters.
