Abstract

The invention discloses a fin type ultraprecise air static pressure coupling device. A transmission structure is designed through the air static pressure technology. Driving force is transmitted between a driving system and a driven component through an air film formed by high-pressure air, and the effect to the movement of the driven component from vibration, impact and the like produced by the driving system is easily and effectively reduced. Due to the fact that the fin type ultraprecise air static pressure coupling device can carry out tiny position adjustment through the air film, the demand for installation precision can be lowered appropriately. Due to the fact that the characters of the air static pressure, a whole set of air supplying device needs to be arranged, the demand for the environment is high, and using is limited to some degree.

Description

technical field [0001] The invention relates to the technical field of ultra-precision transmission, in particular to a finned ultra-precision aerostatic coupling device. Background technique [0002] In the field of ultra-precision transmission technology, how the transmission system can accurately transmit the driving force of the drive system to the driven part without affecting the self-motion of the driven part is the principle that the transmission device must abide by. However, due to its structural characteristics, the traditional rigid and elastic transmission structure requires high installation precision of the transmission structure, complex assembly and adjustment process, and adverse effects such as vibration and impact are transmitted directly to the movement accuracy of the driven part through the transmission structure. The existing transmission structure is inevitable. Contents of the invention [0003] The purpose of the present invention is to overcome...
