项目摘要

The angular contact ball bearings are frequently adopted as the bearing for the spindle of the machine tools. In recent years, these bearings used in machine tools such as machining centers have been required to operate under extremely high speed and heavy load conditions. In order to make clear the causes of heat generation, friction loss and tribo-failures such as smearing in high speed ball bearings, it is indispensable to grasp the contact conditions between ball and races or between ball and separator, and the development of measuring method of the actual ball motion has been desired. Using a magnetized ball and hall elements arranged on the fixed oblique coordinates, the authors tried to measure the behaviour of the ball motion in the angular contact ball bearing 7209A. The results were compared with those of the conventional method with a moving orthogonal coordinate system. Furthermore, the ball motions in the angular contact ball bearing under combined radial and axial loads were also measured. The results obtained are summarized as follows.1.It was confirmed that the measured values such as the rotational speed of the ball and the separator almost agree by two different methods and it was recognized that the prepositional method is practical use and useful.2.Especially, it was recognized that the rotating speed of ball extremely decreased under high speed and light load conditions.3.The ball motion of the angular contact ball bearing is affected by the combined load, and this tendency became remarkably with increase in the shaft speed.4.Furthermore, it was recognized that the load distribution obtained by the numerical analysis has a close relation to the ball motion.

角接触球轴承经常采用作为机床主轴的轴承。近年来，加工中心等机床上使用的这些轴承被要求在极高的速度和重负载条件下运行。为了弄清楚高速球轴承中发热、摩擦损失和擦伤等摩擦故障的原因，必须掌握球与座圈之间或球与分离器之间的接触条件，并且需要开发实际球运动的测量方法。作者使用布置在固定斜坐标上的磁化球和霍尔元件，尝试测量角接触球轴承 7209A 中球运动的行为。将结果与移动正交坐标系的传统方法的结果进行了比较。此外，还测量了角接触球轴承在径向和轴向联合载荷下的球运动。所得结果总结如下： 1. 证实了两种不同方法测量的球和分离器的转速等测量值几乎一致，并认识到前置法是实用且有用的。 2. 特别是，认识到在高速和轻载荷条件下，球的转速急剧下降。 3. 角接触球轴承的球运动受到组合载荷的影响，并且随着载荷的增加，这种趋势变得显着。 4.此外，人们认识到，通过数值分析获得的载荷分布与球的运动有着密切的关系。
