一轴承的一般性质在高速度的转动机器上,轴承是不可缺少的重要零件之一。除了要求有很高的加工尺寸准确精度、和工作表面的精度以外,对于制造轴承材料的品质和热处理方法,也是直接决定它使用寿命的主要因素。轴承在工作的时候,内圈、环圈、滚柱、和滚柱受到下面几种作用: (1)每单位面积受到很大的重复负荷,使金属发生疲劳现象。 (2)由于尺寸制造的不够精确或装配不好,使发生磨擦作用而损坏。 (3)和空气或者润滑油中的杂质接触,发生化学磨损作用。 (4)磨料的磨损作用。 (5)滚珠和滚柱受到外加负荷的压碎作用。是苏联滚珠轴承钢的化学成分。
A bearing of the general nature of the machine in the high-speed rotation, the bearing is an indispensable one of the important parts. In addition to requiring high accuracy of the machining dimensions and accuracy of the working surface, the quality of the bearing material and the heat treatment method are also the main factors that directly determine its service life. Bearing at work, the inner ring, ring, roller, and roller by the following several effects: (1) per unit area subject to a large repetitive load, the metal fatigue phenomenon. (2) due to the size of the manufacturing is not precise enough or assembly is not good, so that the role of friction and damage. (3) In contact with air or oil impurities, chemical wear occurs. (4) abrasive wear effect. (5) balls and rollers subjected to an applied load crushing effect. Is the chemical composition of the Soviet ball bearing steel.
