Problems solved by technology

The structure design of the elastically supported painting turbine is unreasonable, and the vibration amplitude exceeds the standard during start-stop and working conditions
The air-floating-supported painting turbine has the phenomenon of gas vortex causing irregular vibration of the rotor shaft in the air-floating bushing, causing uneven paint film thickness and "orange peel" phenomenon on car panels, and causing turbine discs and rotors to lose stability. Reduced shaft life

Abstract

The invention relates to a high-speed air floatation turbine device, mainly comprising a turbine disk, an end cap of the turbine disk, a hollow shaft, an air flotation bush, a bearing front cap and a bearing rear cap; among the components, the hollow shaft rear is provided with a shaft shoulder; the clearance of the shaft shoulder is embedded between the end cap of the turbine disk and the air floatation bush in a matching way; the front circumference of the end cap of the turbine disk is provided with an axial air floatation supporting air inlet that communicates an intake chamber of floating air to the back end surface of the shaft shoulder of the hollow shaft, and the rear circumference of the air flotation bush is provided with an axial air floatation supporting air inlet that communicates the intake chamber of floating air to the front end surface of the shaft shoulder of the hollow shaft. The device is the highly innovative high-speed air floatation turbine device, and has the advantages of compact structure, scientific and reasonable design, high reliability and long service life; and by providing radial and axial stable support for the hollow shaft by floating air, the device is effectively ensured to operate smoothly at high speed.

Description

technical field [0001] The invention relates to an air-floating turbine device, in particular to a high-speed air-floating turbine device. Background technique [0002] Automatic electrostatic spraying is an important process in the production of medium and high-end cars. At present, automatic electrostatic spraying is mainly realized by the spraying turbine, which drives the spray cup to rotate at a high speed of 35,000 to 40,000 rpm, so that the paint forms extremely fine mist particles under the action of strong centrifugal force, and with the help of high pressure The electrostatic field is evenly attached to the body panels. It can be seen that the working state of the painting turbine plays a vital role in the appearance quality of the automobile panel. Therefore, in order to ensure the continuous normal operation and spraying quality of the automatic electrostatic spraying line under the condition of large-scale production, the spraying turbine is required to have t...
