重型南京nsk轴承一般用于铁路车辆、设备和重工业中，但由于其轴载范围较大，即使同一系列轴承，在不同的情况下，载荷也是的。原因包括使用、维护和长期需求。因此，这些因素对于重载轴承的选择是非常重要的。
heavy-duty nanjing nsk bearings are generally used in railway vehicles, equipment and heavy industry, but because of their large axle load range, even if the same series of bearings, in different circumstances, the load is the largest. the reasons include usage, maintenance and long-term demand. therefore, these factors are very important for the selection of heavy-duty bearings.
重型南京nsk轴承必须与重型轴承相结合。重载轴承经常在高应力条件下工作，而轴承的高应力非常敏感，因此各方面的应用技术主要是应力，而慢、慢则有利于延长轴承的使用寿命。
heavy duty nanjing nsk bearings must be combined with heavy duty bearings. heavy-duty bearings often work under high stress conditions, and the high stress of bearings is very sensitive, so all aspects of the application technology is mainly stress, and slow, slow is conducive to extending the service life of bearings.
例如，允许轴向位置的高载荷的机器将使用单个支撑点来增加两个径向载荷，尽管在相同的冲击载荷条件下，两个枢轴南京nsk轴承的寿命不同于原来的单个轴承箱的寿命，并且与预期的相同。ed增量。不止两次。事实上，重载经常使用多个轴承或轴承来支撑枢轴点。
for example, a machine with a high axial load will use a single support point to increase two radial loads, although under the same impact load conditions, the life of the two pivoted nanjing nsk bearings is different from that of the original single bearing box and is the same as expected. ed increments. more than two times. in fact, heavy loads often use multiple bearings or bearings to support pivot points.
为了减少轴承的应力和润滑油膜厚度，所以使用高粘度的润滑剂或润滑脂基础油，并保证良好的润滑条件，粘性润滑剂不会造成过大的摩擦力矩。
in order to reduce bearing stress and lubricant film thickness, so the use of high viscosity lubricant or grease base oil, and ensure good lubrication conditions, viscous lubricant will not cause excessive friction torque.
南京nsk轴承旋转圈的正常干涉比会影响滚道变形和轴承寿命。因此，如果可能的话，可以适当地减少干扰，需求低，表面粗糙度低，并且在故障的情况下可以正常地保持润滑剂润滑。
the normal interference ratio of nanjing nsk bearing rotating ring will affect raceway deformation and bearing life. therefore, if possible, interference can be reduced appropriately, demand is low, surface roughness is low, and lubricant lubrication can be maintained normally in case of failure.
重载滚道的表面摩擦力矩较大，发生啮合表面的蠕动倾向，甚至发生滑动现象。虽然这些现象在滚道中发生，但内部滚道不可避免地是严重的。外环的实际匹配要注意避免过多的间隙，以免油渗入表面，促进打滑，使环易变形，减少南京nsk轴承面积。
the surface friction moment of heavy-duty raceway is large, and the creeping tendency of meshing surface occurs, even the sliding phenomenon occurs. although these phenomena occur in raceway, the internal raceway is inevitably serious. the actual matching of the outer ring should pay attention to avoid excessive clearance, so as to avoid oil infiltration into the surface, promote skidding, make the ring easy to deformation, reduce the area of nanjing nsk bearing.
旋转轴承是小提醒，只有采取有效措施才能关闭它们，允许适当减少重载轴承的干扰，并稍微减少干扰，轴承应力大大增加，当然，厚膜油将受益更多。大型滚动轴承具有滚动面大、配合紧密、密封圈大、变形大、间隙大、接触面积大等特点。
rotary bearings are small reminders that only effective measures can be taken to close them, allowing proper reduction of interference from heavy-duty bearings, and a slight reduction in interference, bearing stress greatly increased, of course, the thick film oil will benefit more. large-scale rolling bearing has the characteristics of large rolling surface, tight fit, large sealing ring, large deformation, large clearance, large contact area and so on.
此外，轴承的承载能力和疲劳寿命被认为是轴承重设备选择的关键步骤，但必须注意的是，随着使用的增加，预测水平将改变轴承的可靠性。
in addition, bearing capacity and fatigue life are considered to be key steps in the selection of bearing heavy equipment, but it must be noted that the predicted level will change the reliability of the bearing as the use increases.
