Abstract

The invention provides an air bearing with reinforced heat conduction. The air bearing with reinforced heat conduction comprises a stator and a rotor rotatably connected with the stator. Intra-stator micro heat pipes are arranged in the stator, and intra-rotor micro heat pipes are arranged in the rotor. The air bearing with reinforced heat conduction has the beneficial effects that conduction of heat in the air bearing can be improved through the intra-stator micro heat pipes and the intra-rotor micro heat pipes, and the temperature gradient and temperature stress inside a structure can be better balanced.

Description

technical field [0001] The invention relates to a bearing, in particular to an air bearing with enhanced heat conduction. Background technique [0002] In addition to the mechanical force, the bearings of the rotating machinery will inevitably generate a lot of heat due to the relative high-speed rotation of the static and dynamic, which will lead to high temperature and thermal stress problems. Too high a temperature will "burn out" the bearing, so the heat must be conducted away to cool the bearing. At the same time, the temperature gradient formed by the uneven temperature field will form thermal stress, and the overload of thermal stress will also damage the bearing, including plastic deformation and cracks. [0003] The air bearing is composed of a rotor and a stator, and the gap between the rotor and the stator is generally tens of microns. Because the heat capacity of the air medium is small, the heat transfer and cooling of air bearings is more difficult than lubri...
