customized ASA sprocket tells: vibration signal from sprocket failure!

(Summary description)A sprocket is a wheel with cog-type buckle teeth, which is used to mesh with a block with an accurate pitch on a link chain or a cable. Sprockets are widely used in mechanical transmission in chemical, textile machinery, escalators, wood processing, three-dimensional parking garages, agricultural machinery, food processing, instrumentation, petroleum and other industries.

Information

A sprocket is a wheel with cog-type buckle teeth, which is used to mesh with a block with an accurate pitch on a link chain or a cable. Sprockets are widely used in mechanical transmission in chemical, textile machinery, escalators, wood processing, three-dimensional parking garages, agricultural machinery, food processing, instrumentation, petroleum and other industries. So do you know what the vibration signal is about the sprocket failure? Follow the customized ASA sprocket editor to have a simple look at it!
1. Time domain characteristics
When the sprocket is symmetrically worn, the tooth side gap becomes larger, and the sine wave-like meshing waveform is usually destroyed, which is the high-frequency and low-frequency vibration caused by the wear of the gear. The percussion vibration frequency that occurs in this environment is a high frequency above 1 kHz, and at the same time, the frequency component of the low frequency meshing in the sine wave also becomes larger.


2. Frequency domain characteristics
When the tooth surface is uniformly worn, the meshing frequency and its harmonic weight nf.(n = 1,2-The position on the spectrogram remains unchanged, but its amplitude changes, and the amplitude of higher harmonics becomes larger More. When analyzing, it is necessary to analyze the amplitude changes of more than 3 harmonics to test this characteristic from the spectrum. It reflects the changes in the meshing frequency and harmonic value of the gear after wear.
In summary, the editor of the customized ASA sprocket tells: about the relevant knowledge of the vibration signal emitted by the sprocket failure.
