重载轴承运转的游隙调整.docVIP

重载轴承运转的游隙调整 良好的润滑不仅可以起到减小摩擦的作用，同时还对轴承和轴上零件具有冷却作用。滚动轴承游隙进行调整以后，摩擦会有所加剧，产生的热量会使整个传动系统温度有所升高。在进行空运转试验之前，一定要首先检查润滑系统各部位供油是否正常，特别是经过预紧的轴承部位，更需要特别留意其润滑油供给充足，工作状况良好。 Good lubrication can not only play a role in reducing friction, but also has a cooling effect on bearing and shaft parts. After rolling bearing clearance adjustment, friction will be intensified, the heat generated by the rising temperature will make the whole transmission system. Before the idle running test, be sure to first check each part of the lubrication system oil supply is normal, especially after a preloaded bearing parts, more in need of special attention to the lubricating oil supply is adequate, working in good condition. 在滚动轴承装配中是否进行游隙的调整和预紧，要根据技术文件提出的装配技术要求决定。具体地说，在装配技术要求中，一般对于高速、重载或旋转精度要求较高的轴承会有调整轴承游隙或预紧的要求，反之，则会保持轴承游隙，装配时仅作轴向固定即可。从轴承的种类上看，对于圆锥滚子轴承、角接触轴承、推力轴承均需要对其游隙进行调整； Whether to proceed with clearance in the bearing assembly, adjustment and preload technical documents according to the request of assembly technology decisions. Specifically, in the assembly technical requirements, generally for high speed and overloaded or rotating accuracy requirement high bearing will be adjust bearing clearance or preload requirement, on the other hand, it will keep the bearing clearance, for axial fixed only when assembly. Look from the kinds of bearings for tapered roller bearings, angular contact bearings, thrust bearings are necessary to adjust the clearance; 产生更多的热量，形成恶性循环。因此，对于经过游隙调整的滚动轴承，必须要保持良好的润滑，以减少摩擦，更重要的是用不断循环流动的润滑油带走大量的热，控制温度的升高，实现传动系统的热平衡。 Produce more heat, forming a vicious cycle. So, for after clearance adjustment of rolling bearings, must want to keep good lubrication, to reduce friction, more important is to take away a large amount of heat with continuously circulating oil, control the rise of temperature, realize the transmission system of the thermal equilibrium. 滚动轴承游隙的调整和预紧工艺，是提高轴承旋转精度和承载能力、降低传动系统振动和噪声的有效手段，操作中除了应达到滚动轴承装配的一般技术要求外，还要重点考虑轴承温升和润滑对调整工作的影响，并且在进行空运转试验之后还要进行细致的检查和二次调整，耐心
