Multi-parameter Test and Analysis of Dynamic Performance for Helical Gearboxes
In order to evaluate the gearbox condition based on dynamic response
a helical gearbox test platform is built in the present work to test and analyze diverse physical parameters
including rotational speed
dynamic transmission error
axis orbit
vibration acceleration
sound pressure and load torque. By adjusting the working condition (shaft speed and load torque) of the gearbox
the assembly accuracy among the components of the gearbox is assessed
and the correlation between different physical parameters is revealed. The results show that the input shaft is misaligned with the motor shaft
and the output shaft suffers the dynamic unbalance; the peak-to-peak value of transmission error is positively correlated with rotational speed
and has a significant correlation with the root mean square value of acceleration and the peak-to-peak value of radial component of the output axis runout at different speeds.
