固体自润滑轴承的优点

he Advantages of the Solid-Lubricant-Inlaid Bearings

1.设计灵活、简单、方便，使用范围广；

供油系统在机械设计上是一件费工，费时的装置，使用固体自润滑轴承在设计时不需要考虑加油装置，节约了加油装置设备，同时可以针对各种特殊场合，把固体自润滑轴承设计成各种形状，以满足各种特殊场合的需要，使用固体自润滑轴承，可以大幅减少机械检修，油料等费用。

2.无油可以使用；

由于固体自润滑剂的线膨胀系数大于金属基体，因此当固体自润滑轴承开始运转时，油膜会转移到对磨件上而实现自润滑，所以固体自润滑轴承可以使用在难以加油以及不能加油或油脂的地方，即使在低速高负载的情况下，也能起到良好的润滑作用。

3.使用成本低；

传统的机械设计，在一定的操作时间内，要经常加油保养，检查油表，供油装置是否畅通，因定期加油导致机体本身及周边环境污染，造成维护保养成本的增加，实现自润滑后，不但可以实现环境整洁，而且大大降低了使用润滑油的成本。

4.高承载、低转速情况下，可发挥优越的性能；

固体自润滑轴承是用离心铸造的高强度合金黄铜作基体，起到承载负荷的作用，用具有良好自润滑性能的特殊配方的石墨作润滑剂，起到自润滑作用，因此它综合了他们的各自优点，即使在高承载，低转速情况下，可发挥优越的性能。

5.往复运动、摇摆运动、起动停止频繁等油膜形成困难的场所，可发挥优越的耐磨性；

固体自润滑轴承润滑剂的排列原则是保证对磨件在运转过程中各个部位都有润滑剂作用，因此排列润滑剂时必须根据对磨件的运动方向来确定润滑剂的排布位置。

6.优越的耐药品性及耐蚀性；

固体自润滑轴承的润滑剂是用特殊配方的石墨、PTFE、二硫化钼等耐磨材料制成的，它具有稳定的分子结构，金属基体可以根据不同金属具有不同的耐药品性和耐蚀性来选择，因此固体自润滑轴承具有优越的耐药品性和耐蚀性。

7.产品成本更具有竞争力，与同类产品相比，工作寿命较长，所需维护保养甚少，替代更换周期长，性能好。

1. Properly and simply designed, widely used;

Oil offering system is an energy waste and time waste set in mechanical design. There is no needs for considering the oil-putting set in design when using the solid lubricant bushing so it can save the oil-putting equipment and at the same time it also design the solid-lubricant-inlaid bushing into alt kinds of shapes in order to meet various needs in special places. Using solid-lubricant. inlaid bushing can reduce the costs of the machinery mending and the oil in wide range.

2. Being used without oil;

Because of the linear coefficient expansion of the solid lubricant is bigger than that of the metal basement, when the solid-lubricant-inlaid bushing starts to operate, the oil film can transfer to the corresponding friction set to make out self-lubricant. So the solid-lubricant-inlaid bushing can be used in places where the oil or grease cannot be added. It can make out the self-lubricant function even though under high load conditions.

3. Low cost for usage;

Traditional mechanical design asks for frequently aiding oil and checking if the oil watch and the offering set are through in certain period. Because adding oil at regular intervals causes the pollution to the machine itself and the nearby surroundings and increase the maintenance cost. And when the self-lubricant is made out, it can not only make the surroundings clean but also decrease the cost of using the lubricant.

4. The superior functions can be brought into play under high load and low rotati ng speed.

The solid-lubricant-inlaid bushing is based on the high intensity brass that is centrifuge cast. And then make out the loading function. Use special graphite that has good self-lubricant properties as lubricant to make out the self-lubricant so that the bushing has included all of their advantages. It can still bring the superior properties into play even under high load and low rotating speed.

5. The wear resistance can be brought into play even In places the oil film form into difficulties because of the reciprocating and rocking movement, starting and stopping;

The arrangement principle of the lubricant of the solid-lubricant-inlaid bushing is to ensure that all the parts of the corresponding friction sets have the lubricant function in the operating procession. So the arrangement place 0f the lubricant should be depended upon the operating direction of the corresponding friction sets.

6. Superior chemical resistance and corrosion resistance;

The lubricant of the solid-lubricant. inlaid bushing is made of special graphite and PTFE. It has steady molecule structures. The metal basement can be chosen according to the different chemical resistance and corrosion resistance of the metal appliance. So the solid-lubricant-inlaid bushing has the superior chemical resistance and corrosion resistance.

7. The products is more competitive, comparing to the similar kinds of products, this kind of products has longer working life and need seldom maintenance. It has longer replacement ci rcle and good properties.

选择使用ACME自润滑轴承的基体材料

轴承的寿命 The Life The Bushing

SPB(650#)固体润滑轴承的寿命，除急剧的烧焦外，通常由轴承内径的磨损量来决定，磨损量主要受摩擦条件的影响，而摩擦又受承载、速度、杂质、材质、表面粗糙度、工作温度、不同运行方式、所使用润滑剂等条件影响，因此，磨损量只能是一个理论估计值，轴承的寿命取决于各种复杂的条件。

The life of SPB(650#) Solid-lubricant-inlaid depends on the wear depth of the inside diameter of the bushing except such condition as acute Singe, etc. The wear depth is influenced by the load speed, foreign matter, material, surface roughness, working temperature, different operating methods and the lubricant used. So the wear depth is only a theoretical estimate value and the life of the bushing depends on all kinds of the complex conditions.

若因供油不良，杂质渗入而使磨损急剧变化时，就很难预测磨损情形。下式为正常情况下由实验得出的磨损量计算式。

If the oil is not provided well, it is hard to estimat the abrasion state when the foreign matters intermingling. the following formula is the computing method.

W=K×P×V×T

K:摩擦系数 Coefficient of Friction[mm/(N/mm²·m/min. hr]

W:磨损量 Wear Depth (mm)

P:承载压力 Load Pressure (N/mm²)

V:线速度 Linear speed (m/min)

T:磨损时间 Wear Time (hr)

从上式中可以看出，若摩擦系数(K)已知，便可根据承载压力(P)、线速度(V)和磨损时间(T)计算出轴承实际磨损量。但是，在各种实际条件下准确计算出摩擦系数K是件非常困难的事情。在理想条件下，摩擦系数K由影响其值的因素因子Ci来决定。

工况条件

Working Conditions

1. 承载压力 Loading pressure

通常所谓承载压力是指轴承承受载荷时，轴承支持的最大载荷除以受压面积。所谓受压面积，当轴承为圆柱时，取与轴承接触部分的载荷方向的投影面积。

The so-called loading pressure generally means that when the bushing is loading, the max load it bears divides the pressed area. And the loading pressed area means the projection area of the connecting parts when the bushing is cylindrical.

2. 线速度 Linear speed

From the above formula you can see that if the coefficient of the friction "K" is known the real wear depth can be computed according to the pressure "P". linear speed "V" and wear time "T". But it is very difficult to calculate "K" under various actual conditions. Under ideal conditions. "K" depends on the factor "Ci" which influences it.

即i.e.K=Ci×k

Ci: 影响磨损量的因素因子Ci=C1 × C2×C 3×……

Ci: Ci=C1 × C2 × C3 × ……Factor genes that influence the wear depth.

K: 理想条件下的摩擦系数 And k is the coefficient of friction under ideal conditions. K=(1-5) × 10⁸[mm/(N/mm²·m/min. hr)]

C：滑动条件系数 Coefficient of sliding conditions

C1：温度条件系数 Coefficient of temperature conditions

C2：环境条件系数 Coefficient of surrounding temperature

C3：使用场所系数 Coefficient of places used

可知，对摩擦面温度的上升，滑动速度V的影响远大于承载压力P的影响。轴承若使用同一PV值，速度V愈大，轴承面温度上升愈快，因此在高温使用时，最好能供给润滑油，增大冷却效果和流体润滑；以求降低摩擦系数，以防高磨损和烧焦现象的发生。

The heat radiated by the bushing is mainly caused by the friction of the bushing. According to the experience we know that the sliding speed "V" affects more than load pressure "P" to the surface temperature. If the bushing uses the same PV value, the higher speed the more quickly temperature ascends. So it would be better to provide lubricant to

工况条件

Working Conditions

enlarge the cooling effect and liquid lubricant by using high temperature in order to reduce the coefficient of the friction and to prevent the high abrasion and burning.

3. PV值 PV value

PV值是衡量轴承磨损极限和使用寿命的重要指标。以承载压力P(N/mm²)和线速度V(m/s)的乘积PV值(N/mm²·m/s)来表示。

PV value is an important guideline to weigh the abrasion limit and the service life of the bushing. It is shown by the load pressure P multiplying the line speed V.

轴承在单位时间，单位面积所产生的摩擦热量Q，以下式表示：

In the unit time the friction heat q caused by the unit area of the bushing can be shown by the following formula.

\mathsf { Q } = \mathsf { / { \partial \mu * \mathsf { p } * \mathsf { v } } { \mathsf { J } } } - kcal/minJ: 热功当量Heat equivalent of work≈4270(N/mm²·Kcal)P: 承载压力 Load Pressure (N/mm²)V: 线速度 Linear speed (m/s)μ：摩擦系数 coefficient of the friction

如果摩擦系数μ略大一些，轴承所产生的摩擦热量跟PV值成正比，这时所产生的热量Q，在经验上就可被认为固体润滑轴承设计时的重要依据。

当轴承运转时，轴承温度受摩擦发生的热量及热量散发情况影响，通常会在一定的温度上稳定下来．若运转持续进行中有杂质渗入，润滑油的性能就会降低，同时由于摩擦粉末的影响，材料的疲劳，此时摩擦面的形态即发生变化，摩擦系数提高，轴承的温度上升，致使摩擦面损伤，而导致烧焦，基于此种情况，轴承的运转温度越低，亦即使用低PV值时，轴承的负荷性较好，寿命延长。所以在设计时，尽可能使用较低的PV值较安全，反之，在详细分析冷却方法，轴的材质，表面粗糙度，配合间隙等因素情况下，欲超越最大PV值使用，也是可能的。

If the coefficient of the friction "μ " is a little bigger, the friction heat and the PV value are in the direct ratio. Then the caused heat Q is commonly considered as the important principle in the solid lubricant bushing design.

When the bushing is running the heat and the heat radiation can be fixed at a certain temperature. If there are foreign matters in the running process, the lubricant property may be reduced and the friction shape may be changed because of the effect of the friction powder and the fatigue of the material. The enhancement of the coefficient of the friction and the ascending of the bushing temperature cause the damage of the friction surface and it will burn at last. Considering such cases, the load property of the bushing will be better and the service life will be longer if the operating temperature of the bushing is lower i.e.using lower PV value. So when designing, use lower PV value to ensure it is safe. Otherwise, it is also possible to use max PV value by carefully analyzing cooling methods, material of the shaft and the roughness of the surface, etc.

F: 垂直承载 uprightness load (N) d: 轴承内径 inside diameter of the bushing (mm) D: 轴承外径 outside diameter of the bushing (mm) B: 滑块宽度 the width of the sliding plate (mm) L: 滑块长度 the length of the sliding plate (mm) N: 回转数 the rotation times (rpm) C: 往复次数 reciprocating times (cpm) θ:摇摆角 the rocking angle (℃) S: 往复长度 the length of the reciprocation (mm) T: 往复一次需要的时间 (sec) time spenging in each reciprocation

4. 最大PV值 Max PV value

所谓最大PV值是在轴承设计时，在轴承的单位投影面积内所承受的载荷及线速度乘积之最大值，使用时请勿超越此值，在设计时应在图1实线范围内.

The so-called max PV value means the max value of the load in the unit projection of the bushing multiplying the linear speed. Do not exceed the value when using it. When designing please be in the range of Fig 1.

对磨轴的条件

The Condition To The Corresponding Frictionshaft

SPB(650#)固体润滑轴承的使用寿命，磨损量，最高PV值，最高使用温度等都受对磨轴材质等条件的影响。

The service life, wear depth, max value and max using temperature of the #650 solid-lubricant-inlaid bushing are all influenced by the corresponding friction shaft material.

1.对磨轴的材质和硬度

The material and hardness of the corresponding bushing

一般情况下使用轴承时，对磨轴的材质可以选用35#以上优质碳素结构钢，Cr12轴承钢或9SiCr合金工具钢等，以上材质经淬火，调质，表面处理后硬度超过轴承硬度，就能收得到比较理想的效果，但当有硬性杂质侵入时，应尽可能选用硬度较高的轴材料，可以得到更好的使用效果。

In most cases, the material of the corresponding friction shaft can be the upwards #35 superior carbon structure steel, Cr12 steel alloy or 9SiCr tool steel alloy. All the above materials are quenched, mixed and surface dealt to reach an ideal effect. But when foreign matters come into, higher hardness bushing materials should be used in order to get better effects.

2. 表面粗糙度 The surface roughness

对磨轴表面粗糙度过大时，轴与轴承的凸起部分会切断油膜，造成两者直接接触，因此，提高对磨轴的表面粗糙度，尽可能缩小油膜间隙，使其接近流体润滑的状态，这样就能提高轴承的使用寿命，一般情况下，我们推荐轴承的表面粗糙度应在Ra0.4以上。

When the surface roughness of the corresponding friction shaft is too large, the bulge of the shaft and the bushing may cut down the oil film so it may cause the direct connection between the two parts. So enhancing the surface roughness of the corresponding. Friction shaft can reduce the space of the oil film and be close to the

lubricant state so that it can prolong the service life of the bushing.
Generally, the surface roughness we recommended is above Ra0.4.

3. 表面处理 The surface treatment

通常情况下，在对磨轴表面所做处理的目的，大致可分为以下三项：

In most cases, the purpose of the treatment to the correspon-ding friction shaft can be divided into 3 items:

a. 提高耐蚀性；

Enhance the corrosion resistance;

b. 提高表面硬度；

Enhance the SU rface hardness of the surface;

c. 使表面光滑，提高润滑性能。

Make the surface flat and enhance the lubricant properties.

对磨轴进行电镀处理，可提高其耐蚀性，而且能够有效防止粗糙磨损，以及提高润滑性能等，同样当对磨轴生锈时，所产生氧化物与异物侵入，同样会出现磨损加剧，因此，我们建议使用者在对磨轴上镀硬铬，另外，在高载荷，微小摇摆运动时，将对磨轴进行适当的热处理也会收到良好的效果，又如在海水中等类似的腐蚀条件下，对磨轴镀上二至三层硬铬，是很有必要的。

It can enhance the corrosion resistance and prevent the roughness wear by the treatment to the corresponding friction shaft, it can also enhance the lubricant property. When the corresponding friction shaft is stain, the coming of the hard oxygen and the foreign matters may also cause an increase in the wear. So we recommend the users plate rigidity chrome on the corresponding friction shaft. Besides, it will get a good result by proper heat treatment on the corresponding friction shaft. It is also necessary to plate two or three rigidity chrome on the corresponding friction shaft.

轴承宽度、厚度

The Wall-Thickness and The Height of The Bushing

1. 轴承高度Theheightofthebushing

轴承内径是由对磨轴的轴径所决定，所以在受载荷条件下，轴承宽度受轴承承载压力P(N/mm)所决定，轴承越宽，其所承受的承载压强相对减小，但此时可能会造成偏位接触，或冷却效果降低，导致轴承寿命减短，相反，轴承宽度太窄时，润滑油会很快从轴承端面流出，因此很难形成油膜，轴承性能相应降低。

The inside diameter of the bushing depends on the shaft diameter of the corresponding friction shaft. So under the load conditions, the heigth of the bushing depends on the load pressure the bushing bears. Thicker the bushing is, lower the intensity of the pressure is. But it may cause the Lean cortact or the decrease of the cooling effect and reduce the bushing life.Contrarily, if the length of the bushing is too short, the lubricant may flow out quickly so that may be difficult to form the oil filmand decrease the bushing property accordingly.

一般轴承以L/D(轴承宽度/轴承内径)的比例在0.5-3的范围内为适当，但应特别注意在高载荷，易引起偏位接触，高转速时引起的发热情形，此时L/D取1以下较适当。

Generally, the proportion of the height of the bushing and the inside diameter of the bushing should be in the scale of 0.5 to 3. But special attention should be paid that heat condition may cause under high load lean contact and high running speed.Then L/d should be below 1.

2. 轴承壁厚 The wall-thickness of the bushing

滑动轴承跟滚动轴承相比，其壁厚限制较小，壁厚薄为其主要的优点之一。

Comparing to the sliding bushing, the wall-thickness of thiskind of
bushing has little limit Thin wall-thickness is one of themain advantage.
一般情况下，壁厚In most cases, the wall-thickness t= (0.05-0.07)d+ (2-5)mm

轴承宽度、厚度

The Wall-Thickness and The Height of The Bushing

当轴承压入座孔后(如图2)，压入时的压力使轴承内外径收缩，这时，外径过盈量δ和内径收缩量△的关系，受座孔强度，材质，表面粗糙度，压入方式等因素而变化。

When the bushing is pressed into the housing, as Fig 2, the pressure put into makes the contraction of both the inside and outside diameter. Then the relation of the OD surplus "δ " and the ID shrinkage "△"is affected by the strength material, the roughness of the surface and the pressing method of the hole.

当座孔强度足够，材质为铁系，轴承材质为铜合金时，内径收缩量 \triangle 可用下式表示式中：
