| Abstract: | The powder metallurgy helical gears manufactured in warm compaction technique have good wearability and low cost. The vibration of operation has the characteristic of frequency band . Wavelet analysis has the advantage of no special limit on noise .Labview is used to design the virtual instrument system for gear vibraion signal and the collected signal will be realtime processed, so the gear transmission system can be monitored and diagnosed. |
