Problems solved by technology
If the tension is insufficient, the transmission belt will be easily broken due to the impact when the unit is running; if the tension is too high, the transmission belt and the tooth groove of the driving wheel will not mesh well, which will also reduce the service life of the transmission belt.
In addition, under harsh environmental conditions, the transmission belt will undergo changes such as oxidation, corrosion, and aging, which will reduce the stiffness and tension of the transmission belt. When the tension decreases to a certain extent, the transmission belt will also break and cause power generation. unit failure
[0003] Existing transmission belt inspection methods are to calculate the natural frequency limits of the long side and short side of the transmission belt with the required tension limit when the transmission belt is installed, and measure the long side and short side of the transmission belt with a frequency meter while adjusting the pretensioner. The natural frequency of the side will eventually make it meet the frequency requirements, so that the transmission belt can reach the best operating state. However, after the generator set has been running for a period of time, there is no corresponding method and standard to detect whether the transmission belt is invalid except for visual inspection. Know the failure risk of the drive belt during use, so as to avoid the loss caused by the breakage of the drive belt

The invention provides a method and device for detecting the abnormity of a driving belt in a driving assembly. The method comprises the steps: obtaining the current inherent frequency of the drivingbelt is obtained; comparing the current inherent frequency with a limit frequency threshold, wherein the limit frequency threshold value is the inherent frequency when the driving belt almost fails; responding to the comparison to judge whether the driving belt is abnormal or not. Through the implementation of the invention, the method and device can detect whether the driving belt may fail in theworking process of a generator set, and timely detect the possible failure risk of the driving belt in time.
Description
technical field [0001] The invention relates to the technical field of fault detection, in particular to a method and device for detecting abnormality of a transmission belt in a drive assembly. Background technique [0002] The driving components such as generator sets must have a certain tension when installing the transmission belt to ensure the transmission performance and pitch efficiency of the transmission belt. If the tension is insufficient, the transmission belt will be easily broken due to the impact when the unit is running; if the tension is too high, the transmission belt and the tooth groove of the driving wheel will not mesh well, which will also reduce the service life of the transmission belt. In addition, under harsh environmental conditions, the transmission belt will undergo changes such as oxidation, corrosion, and aging, which will reduce the stiffness and tension of the transmission belt. When the tension decreases to a certain extent, the transmissio...
