培训材料滚动轴承的硬度关于轴承的硬度，滚动轴承的内外圈和滚动体采用高铬钢GCr15或GCr15SiMn两种轴承钢制造，成品轴承套圈的硬度在洛氏HRC60-65；成品轴承滚动体硬度在洛氏HRC60-66。
其中，GCr15轴承钢制造的钢球硬度在洛氏HRC62-66范围内；GCr15SiMn轴承钢制造的滚子的硬度在洛氏HRC60-64、钢球在洛氏HRC60-66范围内。
也许你不了解是什么洛氏硬度HRC是什么概念，举个例子:家庭用的菜刀的刀锋的硬度一般在HRC50左右，手术刀具和军用刀具的钢材要精纯一些，硬度也在洛氏HRC60以内。
机床金属车削用的合金刀头的硬度常规的也就在洛氏HRC62~65左右。
滚动轴承的硬度相对是比较硬的，成品轴承想再深加工必须用专用设备和工具加工。
轴承热处理发展历程及技术应用效果热处理发展历程（1）清洁热处理热处理生产形成的废水、废气、废盐、粉尘、噪声及电磁辐射等均会对环境造成污染。
解决热处理的环境污染问题，实行清洁热处理（或称绿色环保热处理）是发达国家热处理技术发展的方向之一。
为减少SO2、CO、CO2、粉尘及煤渣的排放，已基本杜绝使用煤作燃料，重油的使用量也越来越少，改用轻油的居多，天然气仍然是最理想的燃料。
燃烧炉的废热利用已达到很高的程度，燃烧器结构的优化和空-燃比的严格控制保证了合理燃烧的前提下，使NOX和CO降低到最低限度；使用气体渗碳、碳氮共渗及真空热处理技术替代盐浴处理以减少废盐及含CN-有毒物对水源的污染；采用水溶性合成淬火油代替部分淬火油，采用生物可降解植物油代替部分矿物油以减少油污染。
（2）精密热处理精密热处理有两方面的含义：一方面是根据零件的使用要求、材料、结构尺寸，利用物理冶金知识及先进的计算机模拟和检测技术，优化工艺参数，达到所需的性能或最大限度地发挥材料的潜力；另一方面是充分保证优化工艺的稳定性，实现产品质量分散度很小（或为零）及热处理畸变为零。
（3）节能热处理科学的生产和能源管理是能源有效利用的最有潜力的因素，建立专业热处理厂以保证满负荷生产、充分发挥设备能力是科学管理的选择。

轴承型号及其含义资料
轴承型号及其含义内径代号：一般情况下轴承内径用轴承内径代号（基本代号的后两位数）×5=内径(mm，例：轴承6204的内径是04×5=20mm。
常见特殊情况：㈠当轴承内径小于20mm轴承内径尺寸为(mm10121517对应内径代号为00010203㈡当轴承内径小于10mm，直接用基本代号的最后一位表示轴承内径尺寸；例：轴承608Z，用基本代号‘608’的最后一位8作内径尺寸，轴承608Z 的内径为8mm。
以此类推627的内径为7mm，634的内径为4mm。
㈢轴承的内径不是5的倍数或者大于等于500mm，内径代号用斜杠‘/’隔开。
另一种情况：有部分滚针轴承旧代号内径代号直接用‘/’隔开。
这几种情况‘/’后边的几位数值为轴承内径尺寸。
见下表示例：轴承型号619/1.562/2260/5003519/11207943/25内径尺寸(mm1.522500112025以上是几种轴承内径常见的表示方法，国际上有些公司的代号都不尽相同；要以实际情况为准。
具体要参考各种资料和各厂家样本。
尺寸系列代号：用于表达相同内径但外径和宽度不同的轴承，见图。
直径代号宽度代号外径系列代号：特轻(0,1,轻(2,中(3,重(4宽度系列代号：一般正常宽度为“0”,通常不标注。
但对圆锥滚子轴承(7类和调心滚子轴承(3类等类型不能省略“0”6010为轻薄系列，应用于轻载荷、高转速；6210是轻型系列，轻型负荷转速最合理，是应用面最广的类型；6310是中重型系列；6410是重系列，用于重载低速。
中型和中重型应用最广，如各类机械传动部件、中小型电动机、流水线传送带、摩托车等等各种机械设备几乎都有用到这两种类型。
类型代号：应记住常用的轴承代号：3,5,6,7,N五类，对应老代号为7，8，0，6，2类。
.公差等级代号见表:向心轴承和角接触球轴承分五级见下表（高→低）新等级代号P2P4P5P6P0旧等级代号B C D E G圆锥滚子轴承分四级见下表（高→低）新等级代号P4P5P6x P015mm 和17mm 的轴承，内径代号依次为00、01、02和03。

INA FAG轴承样本中文版-圆锥滚子轴承
圆锥滚子轴承 JK0S 为单侧密封的即装即用单元，主要用于 O 型 布置配对安装。它们是不可分离轴承，且不需要再注脂。
无需设定轴承对的内部轴向游隙。是因为当用轴螺母或轴端盖 夹紧内圈时，内外圈之间存在非常小的突出量 ( 尺寸 u)。 为了获得正确的安装后轴向游隙，内圈和外圈需要采用紧配合。 整体式圆锥滚子轴承以 O 型布置配对使用时，外圈会形成一个 适宜的环形槽以供卡环 BR 定位。卡环必须单独订购。

The contact angle makes this bearingsuitable for accommodating radial loads, single direction axialloads, and a combination of both. Furthermore, since an axialcomponent is generated when a radial load is applied, thesebearings are generally used in pairs, triplex sets, quadruplexsets, or multiplex sets.Contact AngleWhen a load is applied to an angular contact ball bearing,elastic deformation and the amount of stress at the contactpoint changes as a result of the varying load conditions of theballs, inner ring, and outer ring according to the contact angleof the bearing.Figure 1.2 illustrates loads acting on two rolling elements for a30˚ contact angle, and a 15˚ contact angle. The relationbetween an axial load being applied to the bearing and resultingload acting on the rolling element can be formulated as:F a/(Number of balls ×sinα).Therefore, the larger the contact angle, the smaller the loadacting on the rolling element. Load at the contact point, and itsconsequential deformation, is reduced thus resulting in longerlife. When a radial load is applied, the smaller the contactangle, the smaller the load acting on the rolling element, thusresulting in reduced load at the contact point.(See Pages 42 and 43 for contact angle specifics.)Dimension Series7Bearing type7: single-row angular contact ball bearing42-43, 480Dimension9: 19 series, 0: 10 series, 2: 02 series42-43, 48C Contact angle C: 15˚, A5: 25˚, A: 30˚42-43, 48Material No symbol: bearing steel (SUJ2) SN24: ceramic ball (Si3N4) (1)14-1713Bore numberLess than 03, Bearing bore 00: 10 mm, 01: 12 mm 02: 15 mm, 03: 17 mm50-60Over 04, Bearing bore Bore number × 5 (mm)TYN Cage TYN: ball guided polyamide resin cage; limiting speed d m n= 1 400 000; operational temperature limit = 120˚C18-19TR: outer ring guided phenolic resin cage; operational temperature limit = 120˚CSeal No symbol: open type V1V: non-contact rubber seal (2)32L Preload EL: extra light preload, L: light preload, M: medium preload, H: heavy preload42-43CP: special preload, CA: special axial clearance152-160DB ArrangementSU: universal arrangement (single row) DU: universal arrangement (double row)42-43DB: Back-to-back arrangement DF: Face-to-face arrangement DT: tandem arrangementDBD, DFD, DTD, DUD: triplex set arrangement •DBB, DFF, DBT, DFT, DTT, QU: quadruplex set arrangement148-151P4AccuracyP2: ISO Class 2, P4: ISO Class 4, P5: ISO Class 5151P3: special class (dimensional accuracy: ISO Class 4; rotating accuracy: ISO Class 2)176-179P4Y: special class (Bore diameter and outside diameter are exclusive to NSK.

产品表面采用先进磷化特殊处理，使产品表面形成一层致密、均匀，附着 力好，耐蚀力强的钝化磷化膜，从而增强了轴承与门架间的结合力，提高轴承 表面耐蚀性、耐磨性与润滑性能。

叉车门架链轮轴承的工作原理
9
叉车门架链轮轴承为 抬高货物的主要受力轴 承，传动链条与轴承外 圈链槽配合，轴承内圈 与门架固定连接，要求 轴承有足够的承载能力 和小的摆动量，轴承能 够平稳、灵活运转。

叉车侧链轮轴承
各种结构的叉车侧链轮轴承 包括双列球式、嵌套轴承式、 滚子式、滚针式等。
11
轴承原材料
叉车滚轮轴承内、外圈采用优质真空精炼轴承钢 C&U3或中碳钢，采用定炉质量监控，对非金属夹杂物 的控制要求相当严格，氧含量小于10PPM，毛坯成型采 用哈特贝尔高速镦锻后一次冷辗扩加工工艺，使轴承内 部组织致密、晶粒细小，并具有理想的金属纤维流线分 布，提高了轴承滚道表面的抗疲劳性能。
产品采用现行行业先进的极限载荷设计方案，比一般 轴承额定载荷增加5%；采用优质轴承钢材C&U3，高速 锻工艺，所以轴承实际承载能力通常比其额定载荷大5% 左右，而实际寿命通常为其额定寿命的5～8倍。
双硬度工艺设计：先整体调质处理，使轴承套圈具有一 定的韧性和足够的强度，具有优良的综合机械性能，其调 质硬度30～ 42HRC，调质后再对滚道进行感应淬火处理， 使滚道硬度达到58～ 62HRC，滚道淬硬层3mm以上。然 后去应力回火。保证了轴承滚道与钢球之间的接触疲劳强 度，进而保证了轴承的寿命。由于轴承外表面硬度相对较 低，可以有效降低叉车门架的磨损，提高门架的寿命。
