Research on the Injection Performance of a Novel Lubricating Device Based on Piezoelectric Micro-Jet Technology

In order to solve the problem of lubrication failure in bearing systems, a novel lubricating device which can achieve drop-on-demand lubrication is proposed based on piezoelectric micro-jet technology. The injection performance of the novel piezoelectric micro-jet lubricating device are analyzed in... Full description

description: In order to solve the problem of lubrication failure in bearing systems, a novel lubricating device which can achieve drop-on-demand lubrication is proposed based on piezoelectric micro-jet technology. The injection performance of the novel piezoelectric micro-jet lubricating device are analyzed in this paper. The influences of the fluid–structure interaction to the working frequency are studied by comparing the results of tests with simulations. A method used to forecast the working frequency of the micro-jet is proved to be available. A velocity inlet boundary model at the nozzle is derived under the assumption that the lubricating oil cannot be pressed. Combined with this model, the influences of density, dynamic viscosity and surface tension of the lubricating oil on the injection performance are discussed according to the simulation results. An experiment on the injection performance of the micro-jet for ejecting lubricating oil with different dilution ratios is performed. The recommended excitations are given for ejecting lubricating oil with different properties by analyzing the results.
