球面滚子轴承用作***端轴承。位于发电机侧的南京NSK轴承位于轴承的正确距离处。这种尺寸的轴承的间隙选择需要结合传动链更充分和动态地考虑，并且与行星架轴承及其齿轮箱在齿轮箱中的安装有关。
Spherical roller bearings are used as locating end bearings. The Nanjing NSK bearing on the generator side is located at the right distance from the bearing. The clearance selection of bearings of this size needs to be c***idered more fully and dynamically in conjunction with the tran***ission chain, and is related to the installation of planetary frame bearings and their gearboxes in gearboxes.
这种自调心轴承有助于容纳两个轴承，主轴偏转，角度偏差和偏心。由于滚动元件是自对准的，所以滚动元件总是在适当的位置，所以负载均匀地分布在滚动元件的长度上。即使发生挠度或轴向位移，轴承仍能保持较高的承载能力。
This self aligning bearing helps to accommodate two bearings, spindle deflection, angular deviation and eccentricity. Since the rolling element is self-aligned, the rolling element is always in place, so the load is evenly distributed over the length of the rolling element. Even if deflection or axial displacement occurs, the bearing can still maintain a high bearing capacity.
由于良好的性能，两点南京NSK轴承环滚子轴承和球面滚子轴承被预先指定用于新的8MW模块化风力涡轮机和齿轮箱。基于空心轴设计，可以使用直径为1700至1800mm的滚子轴承和直径为1200至1300mm的球面滚子轴承。轴承。它还提供了新一代滚子轴承和球面滚子轴承。轴承的性能参数在耐久性、操作能力和动态承载能力方面都有很大的提高。性能改进归功于使用高质量的钢，导致更高的疲劳强度，优化的X位置热处理和均匀的南京NSK轴承负荷分布。
Due to good performance, two-point Nanjing NSK bearing ring roller bearings and spherical roller bearings were pre-assigned for use in new 8MW modular wind turbines and gearboxes. Based on the hollow shaft design, roller bearings of 1700 to 1800 mm in diameter and spherical roller bearings of 1200 to 1300 mm in diameter can be used. Bearing. It also provides a new generation of roller bearings and spherical roller bearings. The performance parameters of bearing h***e been greatly improved in durability, operation ability and dynamic bearing capacity. Performance improvements are attributed to the use of high quality steel, resulting in higher fatigue strength, optimized X-position heat treatment and uniform load distribution for Nanjing NSK bearings.
它还面临着为轴承尺寸提供个性化轴承座设计的挑战。在设计中，充分考虑了支承块的受力和变形，获得了更效率的载荷分布。此外，接触式或迷宫式密封可以根据润滑或（可能将来使用油润滑）集成到轴承座中。
It also faces the challenge of providing personalized bearing block design for bearing dimensi***. In the design, the load and deformation of the supporting block are fully taken into account, and a more efficient load distribution is obtained. In addition, contact or labyrinth seals can be integrated into the bearing seat according to lubrication or (possibly future use of oil lubrication).
一般来说，在运行之前，南京NSK轴承设备的转子须是静态的和动态的。万向轴承没有问题。但是，一些转子在运行中由于腐蚀或固体杂质磨损，或轴弯曲，会导致离心力不平衡，使轴承发热、振动、滚道磨损严重，直至损坏。
Generally speaking, before running, the rotor of Nanjing NSK bearing equipment must be static and dynamic. There is no problem with universal bearings. However, some rotors in operation due to corrosion or solid impurities wear, or shaft bending, will lead to unbalanced centrifugal force, so that bearing heating, vibration, raceway wear serious, until damage.
操作时，按规定定期检查万向节轴承。如有发热、异常声音和振动，及时停机，查明原因并排除故障。如果严重的疲劳剥落、氧化锈、磨损坑、裂纹、轴承硬度降低到HRC<60，或者噪声太大，不能调节，则应停止。时间的变化。如果检查和更换不及时，将造成严重的损坏甚至轴承转子，从而影响正常生产。此外，南京NSK轴承拆卸不当，设备脚螺栓因振动松动，还会导致轴承滚道和滚动压痕，轴承内外座圈产生裂纹。
During operation, the universal joint bearings are regularly checked according to the regulati***. If there is fever, abnormal sound and vibration, stop in time, identify the cause and troubleshoot. If serious fatigue spalling, oxidation rust, wear pits, cracks, bearing hardness is reduced to HRC < 60, or the noise is too large to adjust, it should be stopped. The change of time. If the inspection and replacement is not timely, it will cause serious damage or even bearing rotor, thus affecting normal production. In addition, Nanjing NSK bearing disassembly improper, equipment foot bolt vibration loosening, but also lead to bearing raceway and rolling indentation, bearing inner and outer seat ring cracks.
