Abstract
The invention relates to a mixed type helical groove dynamical and static pressure gas composite thrust bearing, which is high speed, high rigidity, big load and ultraprecise. On the working surface of the thrust bearing, static pressure air-floating air feed point distributed at two sides of the circle respectively opens herringbone dynamical pressure groove. The bearing capacity of the bearing is improved more than 30% compared to the traditional static pressure air-floating bearing in the circumstance of not adding the gas consumption of the air-floating bearing and the bearing rigidity is improved more than 15% compared to the static pressure air-floating bearing.
