一般来说,NSK轴承中的滚动轴承本身不产生噪音。通常感觉到的“轴承噪音”事实上是NSK轴承直接或间接地与周围结构产生振动的声音效应。
In General, NSK bearings of rolling bearing in itself does not produce noise. Often feel "bearing noise" is in fact NSK bearing directly or indirectly to the surrounding structure have a vibration sound effect.
这就是为什么许多时候噪音问题可被视为涉及到整个NSK轴承应用的振动问题。因加载滚动体数量变化而产生的激振当一个径向负荷加载于某个轴承时,其承载负荷的滚动体数量在运行中会稍有变化,即:2-3-2-3....这引起了负荷方向的偏移。由此产生的振动是不可避免的,但可通过轴向预加载来减轻,加载于所有滚动体。
This is why many noise problems can be viewed as involving the entire application of NSK bearings vibration problems. Result of loaded rolling quantity change vibration when a radial load is loaded at the time of a bearing, its bearing load of scroll amount may vary slightly in the running, namely: 2-3-2-3 .... Cause a load offset in that direction. The resulting vibration is inevitable, but provide an axial preload to reduce load all the rolling.
部件的波度在轴承圈与轴承座或传动轴之间密配合的情况下,NSK轴承圈有可能与相邻部件的外形相配合而变形。如果出现变形,在运行中便可能产生振动。因此,把轴承座和传动轴进行机加工到所需的公差很重要。
Parts of wave in snug fit between the bearing rings and bearings or shafts cases, NSK bearing ring might dovetail shape and deformation of the adjacent parts. If the deformation occurs, there may be in the running vibration. Therefore, and drive shaft housings are machined to required tolerance is very important.
局部损坏由于操作或安装错误,小部分NSK轴承滚道和滚动体可能会受损。在运行中,滚过受损的轴承部件会产生一特定的振动频率。振动频率分析可识别出受损的轴承部件。应用场合中的振动行为在许多应用中,NSK轴承的刚度与周围结构的刚度相同。由于这个特点,只要正确地选择轴承(包括预负荷和游隙)及其在应用中的配置,就有可能减低应用中的振动。
Partial damage because the operation or installation errors, a small number of NSK bearing raceways and rolling elements may be damaged. Running, scroll past the damaged bearing part leads to a specific vibration frequency. Bearings vibration frequency analysis can identify damaged parts. Vibration behavior of applications in many applications, the NSK bearing stiffness and rigidity of the structure around the same. Because of this feature, as long as the proper selection of bearings (including preload and clearance) and its application in the configuration, it is possible to reduce vibrations in the application.
