固有震动所致江苏INA轴承中的发生源

滚道噪声的来源是由于加载后的环的固有振动。由于江苏INA轴承套圈与滚动体之间的弹性接触，形成了非线性振动系统。当光滑或加工精度不高时，会引起与此弹性特性相关的固有振动，并转移到空气中会成为噪声。
The origin of raceway noise is due to the natural vibration of the loaded ring. Due to the elastic contact between Jiangsu INA bearing ring and rolling element, a nonlinear vibration system is formed. When smooth or machining accuracy is not high, it will cause natural vibration associated with this elastic property and transfer to air will become noise.
众所周知，即使是较先进的制造轴承零件，具有较先进的制造技能，在任务表面总是会有小的几何误差，然后滚道和滚动体之间的微小摇摆引起振动系统的振动。
It is well known that even the most advanced manufacturing bearing parts, with the most advanced manufacturing skills, always have small geometric errors on the task surface, and then the small swing between the raceway and the rolling body causes vibration of the vibration system.
虽然江苏INA轴承的滚道噪声是不可防止的，但它能接受高精度加工零件的外观，选择轴承并准确地使用轴承，以减少噪声和振动。轴承主要是在NNU设计（图1）和双列SKF圆柱滚子轴承（图2）中生产的。
Although the raceway noise of Jiangsu INA bearing is not prevented, it can accept the appearance of high precision machining parts, select bearings and use bearings accurately to reduce noise and vibration. The bearings are mainly produced in NNU design (Figure 1) and double row SKF cylindrical roller bearings (Figure 2).
这些江苏INA轴承可以分开，也就是说，带有整个凸缘的轴承环、滚子和齿条部件可以用其它轴承环来识别，并且可能所有轴承部件都可以被识别。这使得这些轴承的安装、反射和维护成为可能。双列圆柱滚子轴承有圆柱孔和圆锥孔，用神经网络设计的江苏INA轴承通常具有锥形孔。当安装有锥形孔的轴承时，可以达到必要的径向内部间隙或不可避免的预载荷。
These Jiangsu INA bearings can be separated, that is to say, bearing rings, rollers, and rack parts with the entire flange can be identified with other bearing rings, and all bearing parts may be identified. This makes installation, reflection and maintenance of these bearings possible. Double row cylindrical roller bearings have cylindrical holes and tapered holes, and the Jiangsu INA bearing designed by neural network usually has tapered holes. When bearings with tapered holes are mounted, the necessary radial internal clearance or unavoidable preload can be achieved.
预紧意味着在接收负载之前，江苏INA轴承可以在改变工作台环的相对位置之前用于间隙。对于家用轴承，预紧的主要影响是渐进轴承刚度，当径向载荷受到振动和噪声NSK轴的抑制时，由于存在径向间隙，只有局部钢球接受载荷（ABC），称为轴承区域，而另一个则称为轴承区域。
Preload means that before the load is received, the INA bearing of Jiangsu can be used for clearance before changing the relative position of the table ring. For household bearings, the main effect of pre tightening is progressive bearing stiffness. When radial loads are suppressed by vibration and noise NSK axes, only local steel balls accept load (ABC) due to the existence of radial clearance, which is called bearing area, and the other is called bearing area.
被称为非承载区。在钢球从非承载区到D′D的运动过程中，钢球的自重与离心力之间的连接力的大小和偏转不时发生变化。江苏INA轴承钢球被内圈滚道代替，然后发生轴承内部的声音。这种异常声音可以通过预紧轴承来消除。
It is called a non - bearing area. During the movement of the ball from the non load zone to the D 'D, the magnitude and deflection of the connection force between the gravity and centrifugal force of the steel ball change from time to time. Jiangsu INA bearing steel ball is replaced by inner race raceway, and then the internal sound of the bearing is generated. This abnormal sound can be eliminated by pre tightening bearings.
