Abstract

The invention discloses a static pressure air floatation supporting device with an extrusion film assisting in pressure stabilization. The static pressure air floatation supporting device comprises an air supply device, a floating body and a carrier, wherein the floating body and the carrier are oppositely arranged, and the air supply device introduces air flow between the floating body and the carrier to form a static pressure bearing air film between the floating body and the carrier. The static pressure air floatation supporting device further comprises a high-frequency vibration generator mounted on the carrier, and the high-frequency vibration generator drives the carrier to vibrate at high frequency. According to the static pressure air floatation supporting device, the effect of restraining low-frequency vibration of the static pressure bearing air film can be achieved, it can be further avoided that the floating body generates resonance along with the static pressure bearing air film, and then the stability of air floatation bearing resonance is improved.

Description

technical field [0001] The invention relates to the field of air-floating supports, in particular to a static-pressure air-floating supporting device and a control method for assisting pressure stabilization by extruding membranes. Background technique [0002] Gas bearings and air bearings are commonly used support methods in modern industries. They generally include a carrier and a floating body. The carrier and the floating body face each other up and down. A constant-pressure airflow is introduced to form a static pressure bearing air film between the carrier and the floating body, and the static pressure bearing air film makes the floating body float upward relative to the carrier, thereby forming a support for the floating body. [0003] In the application of air bearing technology such as gas bearing and air bearing and transmission, the stability control of air bearing is one of the technical difficulties. Due to the low stiffness of the static pressure-bearing air ...
