一、接触疲劳强度
Contact fatigue strength
轴承在周期负荷的作用下,接触外表很轻易发作疲惫破坏,即涌现龟裂剥落,这是轴承的重要破坏情势。因而,为了进步轴承的运用寿命,轴承钢必需具备很高的接触疲惫强度。
Bearing in the role of periodic load, contact appearance is very easy to break out of fatigue, that is, the emergence of cracking and spalling, which is an important damage to the bearing situation. Therefore, in order to improve the service life of bearing, bearing steel must have very high contact fatigue strength.
二、耐磨性能
Two. Wear resistance
轴承任务时,套圈、滚动体和维持架之间不只发作滚动摩擦,而且也会发作滑动摩擦,从而使轴承零件一直地磨损。为了增加轴承零件的磨损,维持轴承精度稳固性,延伸运用寿命,轴承钢应有很好的耐磨性能。
During the bearing task, not only rolling friction occurs between the ring, the roller and the maintainer, but also sliding friction occurs, so that the bearing parts have been worn out. In order to increase the wear of bearing parts, maintain the stability of bearing accuracy and extend the service life, bearing steel should have good wear resistance.
三、硬度
Three, hardness
硬度是轴承质量的重要质量之一,对接触疲惫强度、耐磨性、弹性极限都有间接的影响。轴承钢在运用状况下的硬度个别要到达HRC61~65,能力使轴承取得较高的接触疲惫强度和耐磨性能。
Hardness is one of the important qualities of bearing quality, which has indirect influence on contact fatigue strength, wear resistance and elastic limit. The hardness of bearing steel should reach HRC61 ~ 65 in operation, which makes the bearing obtain higher contact fatigue strength and wear resistance.
四、防锈性能
Four. Rust preventive properties
为了避免轴承零件和成品在加工、寄放和运用历程中被侵蚀生锈,请求轴承钢应具备良好的防锈性能。
In order to avoid corrosion and rust of bearing parts and finished products during processing, storage and operation, it is required that bearing steel possess good anti-rust performance.
五、加工性能
Five, processing performance
轴承零件在消费历程中,要经过许多道冷、热加工工序,为了满意少量量、高效力、高质量的请求,轴承钢应具备良好的加工性能。例如,冷、热成型性能,切削加工性能,淬透性等。
In the course of consumption, bearing parts have to go through many cold and hot working procedures. In order to satisfy the requirements of small quantity, high efficiency and high quality, bearing steel should have good processing performance. For example, cold, hot forming, cutting performance, hardenability and so on.
轴承钢除了上述基础请求外,还应当到达化学成分恰当、外部组织平均、非金属搀杂物少、外部外表缺点契合规范以及外表脱碳层不超越规则浓度等请求。
In addition to the above basic requirements, bearing steels should also meet the requirements of proper chemical composition, average external microstructure, less non-metallic dopants, conformity to the specification of external appearance shortcomings and non-exceeding the regular concentration of decarbonization layer.
