润滑对轴承的运行和寿命有着非常重要的影响。简要介绍了油脂的选择原则。润滑脂由基础油、增稠剂和添加剂组成。不同等级润滑脂的性能与同等级润滑脂有很大的不同。注意选择很重要。润滑脂的性能主要取决于基础油。高粘度适用于高温高负荷。浓密机的润滑性能也与之有关。增稠剂的耐水性决定了润滑脂的耐水性。
Lubrication has a very important impact on the operation and life of bearings.
Lubricating grease c***ists of base oil, thickener and additive. The performance of different grade greases is quite different from that of the same grade greases. It's important to pay attention to choices. The performance of grease mainly depends on base oil. High viscosity is suitable for high temperature and high load. The lubrication performance of the thickener is also related to it. The water resistance of the thickener determines the water resistance of the grease.
1。INA组合轴承设备准备
1. INA Composite Bearing Equipment Preparation
（1）轴承安装应清洁：安装现场应与车床、磨床等机械设备保持一定距离。现场应清洁干净，并始终坚持干燥、清洁、进水轴承。对轴承箱（座）、轴等相关部件进行反思，确保其清洁。轴承应留在原包装中，直到安装前一刻，以避免污染。
(1) Bearing installation should be clean: the installation site should keep a certain distance from the lathe, grinder and other mechanical equipment. The site should be clean and clean, and always adhere to dry, clean, water inlet bearing. Reflect on the bearing box (seat), shaft and other related components to ensure its cleanliness. Bearings should be left in the original packaging until the moment before installation to ***oid pollution.
原则上，不同品牌的润滑脂不能混合，即使是相同的增稠剂润滑脂，由于添加剂的不同，也会对彼此产生***影响。
In principle, different brands of grease can not be mixed, even the same thickener grease, due to the different additives, will h***e a negative impact on each other.
INA组合轴承表面涂有防锈油。安装使用前，bi须用清洁的***或煤油仔细清洗，然后涂上清洁的优zhi或高速高温润滑脂。清洁度对轴承寿命、振动和噪声有很大影响。但我们要特别提醒您，全封闭轴承不需要清洗和上油。
INA composite bearings are coated with anti-rust oil. Before installation and use, Bi should be carefully cleaned with clean gasoline or kerosene, and then coated with clean Youzhi or high-speed and high-temperature grease. Cleanliness has a great influence on bearing life, vibration and noise. But we would like to remind you in particular that fully enclosed bearings do not need to be cleaned and oiled.
此外，至少14个百分点的密封轴承被轴承污染，不需要进行润滑脂维护。这些轴承仅用于所有早期轴承故障的一小部分。轴承具有优良的制造和设计能力，能在各种恶劣的工作条件下提供密封解决方案。
In addition, at least 14 percent of the sealed bearings are contaminated by the bearings and do not require grease maintenance. These bearings are used only for a ***all part of all early bearing failures. Bearings h***e excellent manufacturing and design capabilities and can provide sealing soluti*** under various harsh working conditi***.
安装条件是使用中***重要的因素之一。INA组合轴承安装不当往往导致整套轴承各部分应力状态的变化。轴承非正常运行和早期使用寿命的内在因素主要是结构设计、制造工艺和材料质量，决定了轴承的质量。
Installation condition is one of the important factors of *** in use. The inappropriate installation of INA composite bearings often results in the change of stress state of each part of the whole bearing. The internal factors of abnormal operation and early service life of bearings are mainly structural design, manufacturing process and material quality, which determine the quality of bearings.
（1）检查轴承是否增加了意外载荷和安装误差，可作为调查轴承损坏原因的线索。
(1) Checking whether the bearing has increased the unexpected load and installation error can be used as a clue to investigate the cause of bearing damage.
（2）轴承的安装参数，如轴承与轴、轴承座的配合、安装时的偏差等，也会影响轴承的振动。
(2) The installation parameters of bearings, such as the matching of bearings with shafts and bearing seats, and the deviation during installation, will also affect the vibration of bearings.
当INA组合轴承转动时，内外环的滚道表面与滚动体接触，使滚道变暗，使滚道与滚道表面的连接正常，从而了解载荷。因此，在拆卸万向节轴承时，请密切注意并观察滚道表面的轨迹。轴承箱承受较大的轴向载荷、轴承力矩载荷或不同的极限刚度。
When the INA combined bearing rotates, the raceway surface of the inner and outer rings contacts with the rolling body, which darkens the raceway and makes the connection between the raceway and the raceway surface normal, so as to understand the load. Therefore, when disassembling universal joint bearings, please pay close attention to and observe the track of raceway surface. Bearing box bears large axial load, bearing moment load or different ultimate stiffness.
（3）轴承状况：在轴承运行过程中，负载、转速和润滑状况对轴承振动的影响***大。
(3) Bearing condition: In the process of bearing operation, load, speed and lubrication condition h***e great influence on bearing vibration.
（4）轴承设计参数：包括轴承滚子数量、环壁厚度和间隙。
(4) Bearing design parameters: including the number of bearing rollers, ring wall thickness and clearance.
轴承零件制造误差：包括INA组合轴承滚道和滚动表面粗糙度。大量实验研究表明，波纹磨损对轴承振动起主导作用，而表面粗糙度和圆度的影响相对较小。
Manufacturing error of bearing parts: including INA combined bearing raceway and rolling surface roughness. A large number of experimental studies h***e shown that corrugated wear plays a dominant role in bearing vibration, while the influence of surface roughness and roundness is relatively ***all.
轴承是精mi零件。线性轴承和润滑脂被污染，无法工作。
The bearing is a precision mi part. Linear bearings and greases are contaminated and cannot work.
（5）轴承检查应在工厂或库存后立即完成。整个检验过程的完成时间不宜过长，以免腐蚀。应注意使用清洁、无油的纯***，这也会引起腐蚀。
(5) Bearing inspection shall be completed immediately after the factory or inventory. The completion time of the whole inspection process should not be too long to ***oid corrosion. Attention should be paid to the use of clean, oil-free pure gasoline, which can also cause corrosion.
