CRB650GT 钢基铜合金镶嵌型固体润滑轴承 CRB650GT Steel shell cast bronze with graphite plug
基材特征Structure
在优质碳钢表面浇铸高强度铜合金作为轴承的基础材料,这种制造工艺使得铜和钢结合面达到完全的冶金结合,在降低了材料成本的同时也提高了其承载能力;而根据使用工况在其工作面镶嵌固体润滑剂大大降低了轴承的摩擦系数并达到了自我润滑的目的。
Steel shell with cast bronze bearing material liner with specially formulated solid lubricants embedded into the holes in the liner material. The process of casting bronze on steel achieves an integral metallurgical structure between bronze and steel with an increasedcarrying capacity while the material cost is considerably reduced. The solid lubricant can reduce the coefficient of friction and performs the self-lubricating function.
金相组织Features
从金相图可以看出临界区的钢与铜合金之间产生了相互扩散,这种在铸造过程中产生的扩散层大约在3μ\~5μ之间使得两种材料达到了完全的冶金结合形成了很好的结合强度,在任何情况下这种机械强度超过了铜合金本身。
钢和铜相互之间扩散的组织结构提供了这种材料优秀的机械性能,同时可将轴承运作过程中产生的热量及时转移。薄壁的铜合金层使得这种双层材料的热膨胀系数相近,因此650GT材料可以在铸造后根据需要进行热处理,也就是说这种新型的材料可以确保在使用过程中保持很高的精度和机械配合。 in
结合了铜合金的耐磨性和钢的高机械强度性能;
·可以根据工况要求铸造不同的铜合金材料包括低摩擦性能的铅铜合金;
·由于内外层材料具有的不同摩擦系数,可以防止轴承在高载低速工况下的窜动和走外圆;
·可以根据需要在工作面覆着或镶嵌固体润滑剂以达到自我润滑的目的;
·相比纯铜套更具有成本优势,节约利用资源;
·可以进行后期加工,比如钢基体的热处理、合金层车加工等;
·可以根据设计需要在不同的面或者复杂的面上进行一层或多层的铜合金铸造;
·与传统的铜套在使用特性上具有类似的特性,可以适合于不同温度下不同润滑条件下的工况;
·相比纯铜套具有更好的机械承载性能,特别是抗冲击强度
CRB650GT combines the advantages of a metallic bearing and the self lubricating of graphite. It is particularly good for low-speed and high load applications, where external lubrication is not practical. The new based material provides economic solution and even good resistance to shock loads.

材料特性 Material Characteristic
CRB200以优质碳素钢为基体,通过合理的油路设计,在装配时涂上油脂使得其在工作时能较长时间的储存所需要的足够油脂,并且能均匀的分布在轴承及轴的表面上,从而达到了延长使用寿命缩短加油频率的目的;同时由于特殊的油路系统能够存入工作时侵入轴承的灰尘和其它异物,从而最大限度的降低对轴承使用过程中的影响。CRB200另外一个特殊性是在轴承的工作表面经过一种特殊工艺的处理,使其表面覆盖了一层特殊的固体润滑剂,这层特殊的润滑剂在起始动作时能很快的转移到对磨轴的表面上,从而较快的降低了起始摩擦系数,提高了轴承的耐磨性。

P值/V值/PV值的概念
P值:轴承所承载的最大负荷(W)与在轴承上的投影面积(φd×L)相除后即为面压P。 inxin
V值:速度V是对偶轴与轴承之间的相对速度。
PV值:轴承面压P与速度V的乘积为PV值。
P值、V值、PV值并不是各自独立的最大允许值,而是相互关联的设计参数。

自润滑轴承的冷装配要领
冷装配方法
(1) 必须材料
冷媒:液氮、干冰
容器:保温容器(足够大的尺寸,四周敷保温材料的容器)
(2) 作业步骤
①作为冷媒的液氮或干冰的标准冷冻温度为-40\~70℃.
②冷冻时间一般为1小时以上。冷冻时间在配合公差较小的情况下,有必要延长冷冻时间。另外,冷冻时间较短的情况下,和液压压入方法并用也十分有效
③再次测量轴承的外轴尺寸以及套筒的内径尺寸。 JIT在装配过程中,如果异常没有及时发现,可能会造成重大故障。
④将轴套装入套筒时,边转动边迅速装入。
在中途如果中断的话,尺寸将还原,拔出再装配将非常困难。
⑤在摩擦面涂上润滑剂。
注)冬季等温度差不是很大的情况下,将套筒加热至20\~30℃
注)有关不明之处,请咨询晋信轴承销售部。
自润滑轴承的压入方法
自润滑轴承和一般的滑动轴承一样,装配进轴承座后使用的情况较多。压入轴承的情况下,利用心轴或使用液压方式装入轴承座内。压入间隙较小的金属轴承的情况下,对轴承的外径及轴承座的内径进行倒角,使用心轴能轻易压入。
轴承选型Bearing Selection
晋信轴承根据不同的工况条件设计了不同的轴承材料。一般来说,用户在使用和设计时应当根据轴承的使用温度、轴承的承载面压、线速度、耐磨性能要求、运动类型、安装情况、轴承成本等各方面因素综合考虑。
CRB bearing have developed kinds of bearing material According to difference work condition, The user can select the material base on bearing work environment, load, speed, wear resistance request, moving method, installation, the cost of the material etc.
面压计算 Bearing Load:
直套、翻边产品Cylidrncal bushes, flange bushes 止推垫片Thrust washer
F=轴承承载值 Load(N)
L=轴承长度 Bearing Length(mm)
F=垫片承载值 Load(N)
由于受配合间隙、材料强度、轴承倒角、内部油槽等原因的影响,轴承的真正承载面压(Pa)会大于理论计算值(Pmean)。 As the factor of clearance, bushes chamfer, oil groove etc., The actually load ( \mathsf { P } _ { \mathsf { s c t } } )
线速度计算Velocity:
旋转运动Rotating motion
d=轴径Shaft(mm)
n=转数/分 Rpm
往复运动Reciprocating motion
摇摆运动Oscillating motion
d=轴径 Shaft(mm)
C=摇摆频率 frequency(次数/分)
θ=摇摆角度Oscillating angle
s=行程长度 Stoke distance(m)
c=往复频率frequency(次数/分)
PV值计算PV=P×V(N/mm²×m/s)
PV是指轴承在一定的承载和线速度条件下的乘积之和,PV值与轴承的使用寿命成反比关系。因此建议设计时尽量使用比较低的安全的PV值,以确保轴承会有更长的使用寿命。同时在选择材料时也要注意不能超过承载、线速度、使用温度等极限值,并尽可能地小。
PV is the product of the specific bearing load P and the sliding speed V which is very important design data. We recommend design lower PV value will leads to longer service life. Also don't exceed the max. of material load, speed, temp. and lower if possible.
滑动轴承与座孔的装配 The Installation of The Sliding Bushing And The Housing
SF系列轴承在装配前宜先用煤油或柴油清洗干净,然后在机油内浸油、沥干。轴承与座孔装配时,即要保证轴承在座孔中不发生转动和轴向移动,要使轴承外表面与座孔充分接触,一般应保证接触面积大于70%以上,以利于承受载荷和传导摩擦热,SF系列轴承内表面是自润滑塑料,外表面是铜背,钢对钢的摩擦系数比钢对塑料的摩擦系数大,因此采用较轻盈配合,既保证使用时衬衫套不会在座孔内发生相对移动,又不会使衬套外径过大致使衬套内孔变形较大。
对于工作压力较高的场合为避免轴套走外圆,推荐用以下二方法:
1、加大轴套外径尺寸,内孔变形用较正芯棒校正。
2、安装时,座孔涂ZY801厌氧胶,增强轴套与座孔的结合强度。
对于外<55cm的轴承可按图A所示,利用一个带有手柄的压头轴芯,小心操作轻轻压力座孔中。
当轴承外径>55cm时可按图B所示,利用带台肩的手柄以及一个“O”形圈和一个辅助圈小心操作,将轴承压入座孔中。
The Installation of SF Bush
SF bushes should de cleaned in kerosene or diesel oil first, immersed in engine oil and then dried up. When the bush is installed into housing, make sure the bush not rotatingin the housing or moving in the axial direction and at the same time make the

outer surface surface fully contact to the base hole, generally guarantee the contact area over 70%,thus to improve load capacity and transmission of friction heat. The inner surface of SF bush is made of self-lubricating plastic, the outer surface steel backing, The friction coefficient of steel to steel is bigger that of steel to plastic, So we should choose the light-graded tight fit, preventing the axle sleeve from moving in the base when working, and also preventing the inner holes from getting deformed and too big because of the large tight fit of the outer diameter.
Out circle of the axle sleeve should be avoided in the high-pressure working conditions. Two methods are recommended here:
1. Increase the outer dia meter of the axle sleeve, and the deformation of inner holes can be calibrated with calibrating core stick.
2. When installing, apply ZY 801Oxygen-hatred glue in the housing to streng then the combination strength between the axle sleeve and base hole.
For bush (outer diameter<55mm), press the bush into the housing gently and carefully using an core axle with a handle. Fig A.
For bush (outer diameter >55mm), press the bush into the housing gently and carefully using a handle with a shoulder, { \mathsf { a n } } \ { } ^ { \mathfrak { n } } { \mathsf { O } } ^ { \mathfrak { n } } ring and an assisting circle. Fig
