1. Excitation due to changes in the number of loaded rolling elements <br><br>When a radial load is loaded on a bearing, the number of rolling elements carrying the load will change slightly during operation, namely: 2-3-2-3 ... This causes a deviation in the load direction. The resulting vibration is inevitable, but it can be reduced by axial preloading, which is applied to all rolling elements. <br><br>2. Local damage <br><br>Due to operation or installation errors, a small part of the bearing raceways and rolling elements may be damaged. During operation, rolling over damaged bearing components will produce a specific vibration frequency. Vibration frequency analysis can identify damaged bearing components. This principle has been applied to XEZ condition monitoring equipment to detect bearing damage. <br><br>3. The accuracy of the relevant components <br><br>may be deformed due to the shape of the adjacent components when the bearing ring is closely matched with the bearing seat or the transmission shaft. If deformation occurs, vibration may occur during operation. Therefore, it is important to machine the bearing housing and the drive shaft to the required tolerances. Please refer to the section "Dimension, shape and running accuracy of the bearing base and support". <br><br>4. <br><br>If the pollutants operate in a polluted environment, the impurities may enter the bearings and be crushed by the rolling elements. The degree of vibration generated depends on the number, size and composition of the crushed foreign particles. Although it does not produce the typical frequency form, it can hear an irritating noise.

1, due to the load of scroll synthe stousten changes caused by the vibration<br><br>When a radial load is loaded on a bearing, the number of rolling bodies carrying the load changes slightly in operation, i.e. 2-3-2-3.... This causes the shift in the direction of the load. The resulting vibration is inevitable, but can be mitigated by axially preloaded and loaded on to all scrolls.<br><br>2, local damage<br><br>A small number of bearing raceways and rolling bodies may be damaged due to operation or installation errors. During operation, rolling over damaged bearing components produces a specific vibration frequency. Vibration frequency analysis identifies damaged bearing components. This principle has been applied to XEZ condition monitoring equipment to detect bearing damage.<br><br>3, the accuracy of the relevant parts<br><br>In the case of tight fit between the bearing ring and the bearing seat or drive shaft, the bearing ring may be deformed by matching the shape of the adjacent components. If deformation occurs, vibration may occur during operation. Therefore, it is important to machine the bearing holder sands and drive shafts to the required tolerances, please refer to the section "Size, shape and operating accuracy of the bearing base and mount".<br><br>4, pollutants<br><br>If operating in a contaminated environment, impurities may enter the bearing and be crushed by the rolling body. The degree of vibration produced depends on the number, size and composition of the crushed impurity particles, which, although not producing a typical frequency form, can be heard in a disturbing noise.

Local damage<br>Due to incorrect operation or installation, a small number of bearing raceways and rolling elements may be damaged. In operation, rolling through the damaged bearing parts will produce a specific vibration frequency. Vibration frequency analysis can identify damaged bearing components.

Accuracy of related parts<br>When the bearing ring is closely matched with the bearing seat or transmission shaft, the bearing ring may be deformed by matching with the shape of adjacent components. In case of deformation, vibration may occur during operation. Therefore, it is important to machine the bearing pedestal and drive shaft to the required tolerances, refer to the section "dimensions, shape and running accuracy of bearing pedestal and support".<br>4.
