Abstract: A few researches have been carried out in dynamic analysis of gear pump. This work concerns external gear pumps for automotive applications, which operate at high speed, low pressure and presents a sensitivity analysis about the influence of design and operational parameters on the pump dynamic behavior. In previous work, a mathematical modeling was developed for eccentricity of shaft and pump, with the aim of including all the important effects, as well as to get a rather simple model. There are three main sources of noise, vibration and friction considered: Angle of pressure variation and gear meshing. The model has been taken in to account for comparison with experimental vibration data, in a wide range of operational parameters conditions for several profile errors. This paper is concentrated on dynamic analysis of the influence of the main design and operational parameters of the pump dynamic behavior. In particular, the effect of operational pressure, speed and friction, the influence of the clearance in the hydrodynamic bearing and between tooth tip and pump case, and the effect of the operational parameters like stiffness, damping, coefficient of friction, film thickness, speed, friction, load, and torque of the gear will be thoroughly discussed in the paper. Finally, the mathematical model and design could be a very useful and powerful tool in order to evaluate the dynamic improvements for noise, vibration and friction reduction.
Keywords: Gear pump-modeling, control volumes, pressure distribution, radial force on shaft
