南京INA轴承润滑方法常用润滑脂润滑效益！
Nanjing INA bearing lubrication methods commonly used grease lubrication benefits!
与润滑油相比，南京INA轴承润滑脂具有附着力好、无损耗、不滴水、耐压、密封防尘、耐腐蚀等优点。由于润滑脂不易泄漏，润滑脂几乎是持续性润滑，特别是对于立式或斜式机床，采用润滑脂润滑实现连续润滑效果。然而，其主要缺点是，与油润滑耐磨性相比，功率损失较大。并且不能起到良好的摩擦散热效果。影响南京INA轴承选择的主要因素有三个。
Compared with lubricating oil, Nanjing INA bearing grease has the advantages of good adhesion, non-loss, non-dripping, pressure resistance, sealing and dust-proof, corrosion resistance and so on. Because grease is not easy to leak, grease is almost continuous lubrication, especially for vertical or inclined machine tools, using grease lubrication to achieve continuous lubrication effect. However, the main drawback is that compared with the oil lubricated wear resistance, the power loss is large. And can not play a good friction heat dissipation effect. There are three main factors that affect the INA bearing selection in Nanjing.
1，工作速度
1, working speed
工作速度是选择润滑脂的重要因素。公式d n d（mm）可以用来表示轴承内圈的直径，N（r/min）可以用来表示速度。对于轴承，润滑脂的DN值约为0.3×106。
Working speed is an important factor in choosing grease. The formula d n d (mm) can be used to represent the diameter of the bearing inner ring, and N (r/min) can be used to express speed. For bearings, the DN value of grease is about 0.3 * 106.
2，工作负荷
2, workload
当南京INA轴承承受重负荷时，应选择高粘度润滑脂和低渗透性润滑脂，以在接触表面之间形成良好的润滑膜。随着轴承载荷的减小，润滑脂的粘度降低。
When Nanjing INA bearings bear he***y loads, high viscosity grease and low permeability grease should be selected to form a good lubrication film between the contact surfaces. As the bearing load decreases, the viscosity of the grease decreases.
3，工作温度
3, working temperature
润滑脂的选择受温度的影响，温度的变化会引起轴承粘度的变化，从而影响其润滑性能。南京INA轴承润滑脂的粘度不应低于20mm2/S，在选择润滑脂时，应注意润滑脂的滴点、渗透性和低温性能。
The selection of grease is affected by temperature, and the change of temperature will cause the change of bearing viscosity, thus affecting its lubrication performance. The viscosity of Nanjing INA bearing grease should not be lower than 20mm2/S. When selecting grease, the dropping point, permeability and low temperature performance of grease should be paid attention to.
这些都是影响油脂选择的主要因素，但在实践中，很多因素，而且通过选择不同的润滑脂性质，如润湿条件或各种润湿条件，不溶性油应是优先选择，水溶性油应该是。
These are the main factors affecting the choice of grease, but in practice, many factors, and by choosing different grease properties, such as wetting conditi*** or various wetting conditi***, insoluble oil should be the priority, water-soluble oil should be.
