与无内圈滚针轴承配合的轴有什么要求?除了滑动轴承本身以外，轴是一个轴承

What are the requirements for a shaft that matches needle roller bearings without an inner ring? <br>In addition to the plain bearing itself, the shaft is the most important factor in a bearing system. It is in direct contact with the bearing and is affected by the movement of the bearing as well as the bearing. Under normal circumstances, the shaft will also be worn, but the design of the latest bearing series has minimized the amount of bearing wear, which can hardly be measured by traditional measurement methods. The shaft can be distinguished and classified according to the hardness and surface finish of the shaft. The hardness of the shaft is also a very important parameter. When the hardness of the shaft is not enough, the shaft will be run in during the starting phase. It is difficult to form an abrasive surface due to frequent wear. It will also have a positive effect on certain materials, and the wear resistance of plastic bearings will also be strengthened. <br><br>In particular, the wear with the hard chromium alloy shaft is minimal. This optical axis performs best in cooperation with many bearings. In the test, the wear of sliding bearings fitted with this shaft is smaller than that of other shafts. However, it should be noted that if the surface finish of the shaft is high, the chance of crawling of the hard chrome alloy shaft is also high. A decisive influence like this is not suitable for other shaft materials.

与无内圈滚针轴承配合的轴有什么要求?<br>除了滑动轴承本身以外，轴是一个轴承系统当中最重要的因素。它与轴承直接接触，而且与轴承一样受轴承运动的影响。在正常情况下，轴也会被磨损，但是，最新轴承系列的设计已经将轴承的磨损量降到了最小，用传统的测量方法几乎测量不到。根据轴的硬度和表面光洁度可以把轴进行区别和分类。轴的硬度也是一个很重要的参数。当轴的硬度不够时，在起动阶段，轴会被磨合。经常磨损很难形成研磨面。对某一些材料也会产生积极的影响，塑料轴承的耐磨性也会加强。<br><br>特别指出，与硬铬合金轴配合的磨损最小。在与很多轴承的配合中这种光轴表现最好。在测试中与这种轴配合滑动轴承的磨损量比与其它轴配合的磨损量要小。然而， 需要指出的是如果轴的表面光洁度较高， 那么硬铬合金轴出现爬行的机会也较高。像这种决定性的影响并不适合于其它轴材料。
