Abstract: In order to achieve non-contact transportation of heavy load objects, a new non-contact automatic transportation device using aerostatic suspension is proposed. The working principle of the aerostatic bearing and non-contact transportation is studied, and the relative force analysis is carried out. Then, the physical model of the suspension structure and transport structure is established and the experimental prototype is manufactured. The electronic control system of stepping motor is set up and PLC program is designed using WPLSoft software. In addition, the influence of transport pressure and nozzle rotation angle on the transport velocity of heavy load objects is investigated by experiments. The experiment results show that the capability of the aerostatic bearing is enhanced sharply, and the heavy load objects can be transported steadily. When both suspension pressure and transport pressure are 0.2 MPa and the nozzle rotation angle is 32.4°, an object with mass of 1 kg can be transported steadily at velocity of 62.5 mm/s.

Key words: fluid power transmission and control, aerostatic bearing, non-contact transportation, stepping motor, PLC controlling
