Aerostatic pressure bearing with integrated pneumatic tension spring - is for use in a tensioned aerostatically located sledge with separation of sledge and running track by means of air film

摘要

The supply of an automatic adjustment of a constant tension force, the placing of low demands on measurement tolerances for the sledge and the conductor, secure and simple assembly and dismantling, the existence of small tipping movements which the pressure bearing needs to accommodate in order to follow small running track deviations are all factors in the function of the bearing. - The pressure bearing can become powerless on loss of air pressure in the screening of the conductor. An air cylinder is fitted in the feed conduit to the pressure bearing behind the bearing disc, whereby the axial rigidity of the air in the cylinder is only slightly less than that of the air film of the air bearing.
