轴承表面热处理可分为两类：一类是表面淬火和回火热处理，采用振动吸收或隔离装置降低淮安SKF轴承噪音或隔离噪音；另一类是化学热处理。
Bearing surface heat treatment can be divided into two categories: one is surface quenching and tempering heat treatment, using vibration absorption or isolation device to reduce the noise or isolation noise of Huaian SKF bearing; the other is chemical heat treatment.
轴承的化学热处理是将一种或几种化学元素的原子渗入工件表面，从而改变工件表面的化学成分、结构和性能。经淬火和低温回火后，工件表面.具有较高的硬度、耐磨性和接触疲劳强度，而工件的核心具有较高的韧性。
Chemical heat treatment of bearings is to infiltrate atoms of one or several chemical elements into the surface of workpieces, thus changing the chemical composition, structure and properties of the workpiece surface. After quenching and low temperature tempering, the surface of the workpiece has higher hardness, wear resistance and contact fatigue strength, while the core of the workpiece has higher toughness.
轴承化学热处理工件的主要技术参数是淬火深du和表面硬度。用维氏硬度计测定了硬化层深du。you效硬化深du是从工件表面到硬度50 HRC点的距离。
The main technical parameters of bearing chemical heat treatment workpiece are quenching depth Du and surface hardness. The hardening depth Du was measured by Vickers hardness tester. You effect hardening depth Du is the distance from workpiece surface to hardness 50 HRC point.
轴承和化学热处理工件的表面硬度试验与表面淬火热处理工件相似。滚动轴承的噪声之一是轴承本身可以通过维氏硬度计、表面洛氏硬度计或洛氏硬度计进行试验，但渗氮厚度相对较薄，一般不超过0.7mm。此时，洛氏硬度计已不能再使用。
The surface hardness test of bearing and chemical heat treatment workpiece is similar to that of surface quenching heat treatment workpiece. One of the noise of rolling bearing is that the bearing itself can be tested by Vickers hardness tester, surface Rockwell hardness tester or Rockwell hardness tester, but the nitriding thickness is relatively thin, generally not more than 0.7mm. At this time, Rockwell hardness tester can no longer be used.
如果淮安SKF轴承零件局部硬度要求较高，可采用感应加热进行局部淬火热处理。这些零件通常需要在图纸上标明局部淬火热处理的位置和局部硬度值。零件硬度试验应在指定区域进行。洛氏硬度计可用来测试HRC硬度值，如热处理硬化层较浅，表面洛氏硬度计可用来测试HRN硬度值。
If the local hardness requirement of Huaian SKF bearing parts is high, induction heating can be used for local quenching heat treatment. These parts usually need to indicate on the drawing the location of the local quenching heat treatment and the local hardness value. Hardness test of parts should be carried out in designated area. Rockwell hardness tester can be used to test HRC hardness value, such as heat treatment hardening layer is shallow, surface Rockwell hardness tester can be used to test HRN hardness value.
即使烘干机的长度变化很大，也可以通过内滚道和滚动体之间的相对运动进行补偿。无需摆动轴承座；
Even if the length of the dryer varies greatly, it can be compensated by the relative motion between the inner raceway and the rolling body. No need to swing the bearing seat;
球面外圈和与其配合的滑动轴承圈使轴承具有对中能力。
The spherical outer ring and the sliding bearing ring matched with it enable the bearing to h***e alignment ability.
通过直接向轴承供油和从两侧排油，可以获得适当的润滑。
Appropriate lubrication can be obtained by directly supplying oil to bearings and discharging oil from both sides.
用螺栓将圆柱滚子淮安SKF轴承和轴承座固定在机架上，可以减小轴承系统的振动。
The vibration of the bearing system can be reduced by fixing the cylindrical roller Huaian SKF bearing and bearing seat on the frame with bolts.
其余尺寸系列30、22和31的轴承可与自调心圆柱滚子轴承互换，无需修改轴承座。调心圆柱滚子轴承在极.端恶劣的条件下工作。
Bearings of other sizes series 30, 22 and 31 can be interchanged with self-aligning cylindrical roller bearings without modification of the bearing seat. The self-aligning cylindrical roller bearings work under extreme and extreme conditi***.
尺寸稳定性高达200摄氏度。
Dimensional stability up to 200 degrees Celsius.
它能承受来自四面八方的径向力。
It can withstand radial forces from all sides.
在轴向位移较大的情况下，每排滚子上的载荷仍然是均匀的。
In the case of large axial displacement, the load on each row of rollers is still uniform.
附加倾覆力矩，如绳轮力矩或蒸汽接头力矩，可用螺栓将轴承座固定在机架上进行补偿。
Additional overturning moment, such as rope wheel moment or steam joint moment, can be compensated by fixing the bearing seat on the frame with bolts.
螺栓确保淮安SKF轴承座不会在Di震多发地区被提升。
Bolts ensure that Huaian SKF bearings will not be lifted in areas prone to Di earthquakes.
