A seizure-tester for bearing materials was newly designed. A rotating ho11ow cylinder is pressed and rubbed against a stational hollow cylinder, so that the seizure caught be occure between the contact interface of the two cylinders. The contact load is given through a coil spring with various compliance, then the upward moving resistance of upper cylinder specimen can be controlled. After the seizure tests for various bearing materials, it was understood that the seizure is a phenomenon in which the upper component of rubbing pair is lifted up with a grown big-sized adhered particle interposed between the rubbing interface to opposite end of sliding clearance. This fact means that the seizure of materials is one of the formation process of wear particles through mutual material transfer and growth mechanism. Accordingly, it becomes obvious that a strong countermeasure for seizure of materials is to select the material combination as only so-called mild wear, in which the mutual transfer and glowth of adhered partcles scarecely observed at a big scale, is revealed during rubbing, even if the lubrication state becomes poor. As a result, it is seen that the seizure tester designed here is useful to evaluate the antiseizure property of bearing materials.

介绍了一种新型的轴承材料硬度测试仪。一个旋转的空心圆柱体被压靠在一个旋转的空心圆柱体上并与之摩擦，从而在两个圆柱体的接触界面之间发生卡住。通过一个具有不同柔度的螺旋弹簧来施加接触载荷，从而控制上圆柱试样向上移动的阻力。通过对各种轴承材料的咬合试验，了解到咬合是指摩擦副的上部构件被抬起，在摩擦界面与滑动间隙的相对端之间夹有长大的大尺寸粘附颗粒的现象。这一事实意味着，材料的咬合是通过相互的材料转移和生长机制形成磨粒的过程之一。因此，显而易见的是，对于材料的咬合的强有力的对策是选择仅为所谓的轻度磨损的材料组合，其中在摩擦期间，即使润滑状态变差，也显示出在大尺度上难以观察到的粘附颗粒的相互转移和发光。结果表明，本文设计的咬合试验机可用于评价轴承材料的抗咬合性能。
