轴、轴套、孔可以相互配合构成一个转动副,那么请问一下哪个词包含了所有的转动副部件?

对于滑动轴承,轴套和衬套一般是混称的,就是轴套能叫衬套,衬套也能叫轴套.一般壁厚较薄的称为衬套多些,反之则称为轴套多些.
对于一般机械零件,只有轴套,用于轴向定位用.

转向节轴套是在转向节转动部位的轴套,在转向节中起耐磨和减摩作用的.

轴套和轴瓦都相当于滑动轴承的外环,轴套是整体的而轴瓦是分片的.

F=μ(du/dy)A
因为间隙非常小所以间隙间的速度呈线性,即du/dy=u/y.A=πdL=3.14*0.01*0.03=0.000942m^2
y=0.1*10^-3m,μ=1.5Pa•s,u=5cm/s和u=5m/s带入上面的公式得
F=0.7065N（u=5cm/s）
F=70.65N（u=5m/s）
辛苦打出来的.

一次装夹完成外圆、内孔、端面,切断.形状及位置公差就看机床本身的精度了.

你的工艺有问题,应该是：粗车、调质、精车、表面淬火、磨（外径和内孔）、内键槽加工（通槽最好采用线切割,如果是半通内键槽,只好采用插床加工了）

铜合金（copper alloy ）以纯铜为基体加入一种或几种其他元素所构成的合金.纯铜呈紫红色,又称紫铜.纯铜密度为8.96,熔点为1083℃,具有优良的导电性、导热性、延展性和耐蚀性.主要用于制作发电机、母线、电缆、开关装置、变压器等电工器材和热交换器、管道、太阳能加热装置的平板集热器等导热器材.常用的铜合金分为黄铜、青铜、白铜3大类.
黄铜 以锌作主要添加元素的铜合金,具有美观的黄色,统称黄铜.因此不能被磁铁吸附!
白铜 以镍为主要添加元素的铜合金.铜镍二元合金称普通白铜；加有锰、铁、锌、铝等元素的白铜合金称复杂白铜.因此能被磁铁吸附～
建议可以去看一下百度百科的“铜合金”相信对你一定有帮助的!：）

该轴套的配合应该是过度配合,套的孔径要比轴小0.00--0.02,用锤轻打进去即可,（不能漏气和空转它必须跟轴同步转动）他的作用是代替轴本体与填料接触,磨损损坏后,不用换掉整根轴,只要换掉该套即可；有的水泵没有该套,使用磨损后,要把整根轴换掉.

Due to the absorbing by the interference fit between the impeller and the axes,the influence to the axes surface gets rather slight when transfered to the axes.

如果用45号钢的话,精密度会受点影响,很多农用水泵用的都是45号钢,看你的设备要求精度了.
至于公差,内径+0.005---0.02,外径-0.005---0.02就可以了,你用的是6207的轴承,所以这个公差只要不是太大就不会有什么问题的,6207轴承径向游隙有3--4个丝,所以你自己考虑公差值就可以了

Principles of operation
There are at least six common principles of operation:
1.sliding bearings,usually called "bushings","journal bearings","sleeve bearings",or "plain bearings";
2.rolling-element bearings such as ball bearings and roller bearings;
3.jewel bearings,in which the load is carried by rolling the axle slightly off-center;
4.fluid bearings,in which the load is carried by a gas or liquid;
5.magnetic bearings,in which the load is carried by a magnetic field;
6.and flexure bearings,in which the motion is supported by a load element which bends.

上海大学的?

套在转轴上起到定位或保护轴的作用,比如转轴和填料之间就要用轴套,轴套磨损了就更换,成本低；如果轴磨损了更换成本高.一般可以用铸铁做成,也可以用铸钢做成.

磷青铜就好···
牌号这个主要看负载···
不过其实区别不大···

我不太喜欢回答求助.
如果是轴套类零件,选的是铸件,是先粗车外圆和内孔,再精加工内孔然后精加工外圆吗?
没有定式,但有不成文的原则：
1、有利于提高加工效率.
2、有利于工件内外圆交替加工的定位.
3、符合工人的加工习惯.
4、考虑现有工装的利用.
5、根据工件的具体情况.
6、根据设备的具体情况.

The single arm press machine is applied to the correction of axle spare parts and shaped materials, and the press casting of axle sleeve parts, the bending and coining of plates, the stretch plastics of simple parts.It can be used in some industries,such as electrical machine,appliance,and military enterprise,etc.This design will complete the hydraulic system for 5000kn single arm press machine,the check for main engine and parts.By the demonstration of transmission,analysis of control elements and calculations for hydraulic system flow the design for hydraulic system is completed.The main engine of 5000kn single arm press machine with the armed structure can approach works and it’s easy to load and unload the works.Rack and rib can make the whole design for the rack according to the standard and regulations of machine design by reasonably choosing work material.It can finish the force analysis of body.Through the force analysis for the girder and strut it completed the check for other parts.Finally,it can design and check the main cylinder in the body.
In this design the author reasonably designs the hydraulic system,body,main cylinder and all the parts by teacher’s guidance and referring to a large number of document literature.The machine has a large working place,a good guide and rapid speed.
