Summary:In order to obtain the vibration characteristics of helical gear transmission system in actual working conditions, two kinds of CAE software are combined to analyse the helical gear vibration with prestress. CAD software interface is used to import the model into ANSYS, and then multi-point coupling constraint is proposed to obtain the first six natural frequencies and main modes of the plastic and steel gears with speed and load. The results suggest that the design of plastic gears meets the requirement of bending strength, and prestress causes the natural frequency of the plastic gears to increase faster than that of the steel gears. The dynamics simulation of ADAMS multi-body system shows that the meshing frequency of plastic gear is obviously lower than the natural frequency, so the system will not resonate. Research shows that plastic helical gears can replace steel gears for low-speed gear pumps, which provides a research method for miniaturization, lightweight and precision designing of low-speed gear pumps.
