泰州INA轴承NKI75/35对齿轮工作的辅助振动的影响

对于轴承，在工作过程中有许多因素导致其不*良状态。和平时期，我们会遇到一些问题。但是，我们必*须尽快解决这些问题，以避免泰州INA轴承工作出现更多的不利条件。因此，在轴承工作中，会不会出现齿轮不*良问题？这有什么不对吗？今天，工程师安会和你一起解释这个问题。

For bearings, there are many factors leading to their bad state in the working process. In peacetime, we will encounter some problems. However, we must solve these problems as soon as possible in order to ***oid more unf***orable conditi*** for INA bearing work in Taizhou. Therefore, in the bearing work, will there be bad gear problems? Is there anything wrong with that? Today, Engineer Ann will join you in explaining this problem.

当轴承出现严重故障时，轴承可能有显著的特征频率。这些部件单独出现，偶尔作为齿轮振动部件的交叉调制，表面和组成，以及频率差，并且频率会发生变化。

When there is a serious failure of the bearing, the bearing may h***e a significant characteristic frequency. These components appear separately, occasionally as cross-modulation of gear vibration components, surface and composition, as well as frequency difference, and the frequency will change.

轴承的特征频率范围比齿轮宽。因此，泰州INA轴承振动诊断不应在内齿轮范围内进行，而应接受高频等因素的影响。通常选择初始间隙，并且所需的操作间隙仅略大于零。

The characteristic frequency range of bearing is wider than that of gear. Therefore, the vibration diagnosis of INA bearing in Taizhou should not be carried out within the range of internal gears, but should accept the influence of high frequency and other factors. Initial clearance is usually chosen, and the required operating clearance is only slightly greater than zero.

在轴承运行中，滚道声是由轴承环在加载后的固有振动产生的。环与滚动体之间的弹性接触构成了非线性振动系统。当润滑或加工精度不高时，与这种弹性特性相关的固有振动将作为噪声激发并传递到空气中。众所周知，即使采用*****的制造技术对整个偏心轴承零件进行加工，在工作表面也会有不同程度的小几何误差，从而引起滚道与滚动体之间的微小波动和激励。身体。身体。泰州INA轴承振动系统的固有振动。

In the operation of bearings, the raceway sound is generated by the inherent vibration of the bearing ring after loading. The elastic contact between the ring and the rolling body c***titutes a nonlinear vibration system. When the lubrication or processing accuracy is not high, the inherent vibration associated with this elastic property will be excited as noise and tran***itted to the air. It is well known that even if the whole part of eccentric bearing is machined by ** advanced manufacturing technology, there will be different degrees of ***all geometric errors on the working surface, which will cause ***all fluctuati*** and excitati*** between the raceway and the rolling body. Body. Body. The inherent vibration of INA bearing vibration system in Taizhou.

对于普通轴承，建议使用振动控制测试工具。建立噪声质量标准是不适当的。当然，根据国外经验，对于特殊产品，如计算机硬盘驱动系统中的轴承和录像机的CD驱动系统，当使用振动评价不方便时，可以制定噪声测量标准进行评价。

For ordinary bearings, it is recommended to use vibration control testing tools. It is inappropriate to establish noise quality standa***. Of course, according to foreign experience, for special products, such as bearings in computer hard drive system and CD drive system of video recorder, when using vibration evaluation is not convenient, noise measurement standa*** can be formulated to evaluate.

Vibration Control Method for Rolling Bearing of Vibrating Screen

1。轴承的合理选择

1. Reasonable selection of bearings

2。轴承与相关零件的合理匹配

2. Reasonable Matching of Bearing and Relevant Parts

3。提高轴承刚度和必要的预紧措施

3. Improving Bearing Stiffness and Necessary Pre-tightening Measures

4。润滑性好。

4. Good lubricity.

一种是泰州INA轴承外激励引起的固有振动，即轴承内圈、外圈、滚动体、保持架的固有振动。

One is the inherent vibration caused by the external excitation of Taizhou INA bearing, that is, the inherent vibration of bearing inner ring, outer ring, rolling element and cage.

其次，由于滚动体不是理想球体，内外通道的接触点轨迹不是理想圆(圆)，即由运动部件的接触和碰撞引起的强迫振动，包括滚动体和ca的冲击和润滑。通用电器公司。离子。轧辊表面不理想、光滑（粗糙度）。杂质引起的强迫振动与声音密切相关。

Secondly, because the rolling body is not an ideal sphere, the contact point trajectory of the inner and outer passages is not an ideal circle (circle), that is, the forced vibration caused by the contact and collision of moving parts, including the impact and lubrication of the rolling body and ca. General Electric Co. I***. The surface of the roll is not ideal and ***ooth (roughness). The forced vibration caused by impurities is closely related to sound.
