Integrated gas bearing structure

Abstract

The invention provides an integrated gas bearing structure. The integrated gas bearing structure composed of a bearing sleeve and a bearing which are integrally assembled can be directly manufactured in a one-time forming mode through a traditional machining method or a 3D printing method, according to the integrated gas bearing structure, the follow-up machining amount is small, the machining precision is guaranteed, meanwhile, the machining efficiency is obviously improved, and different metal materials can be selected according to the working environment of the required gas bearing. An air inlet hole is formed in the bearing sleeve, a plurality of ventilation pipelines are arranged on the bearing from the edge of the bearing to the center of the bearing, air circularly flows along an air cavity channel through the air inlet hole and enters the interior of the bearing through the ventilation pipelines, and therefore the air is effectively conveyed to the interior of the bearing, and working heat in the interior of the bearing is reduced; and compared with a solid bearing product, the interior of the bearing is more stable in quality, small in heat affected zone and higher in thermal deformation resistance, and compared with a traditional bearing structure, the structure has the advantages that the machining cost is reduced, the use reliability is high, and the application prospect is wide.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to an integrated gas bearing structure. Background technique [0002] Air bearings mainly refer to making full use of gas as a lubricant. The advantage of using gas as a lubricant is that the friction torque and friction coefficient are very small, and this benefit will not cause any pollution to the environment in which it is used and the parts that need to be used. . At the same time, compared with rolling bearings and oil sliding bearings, air bearings have many advantages such as high movement speed, good accuracy, low power, and short service life. They are an ideal supporting part. [0003] Gas bearing mainly refers to making full use of gas as a lubricant. The advantage of using gas as a lubricant is that the friction torque and friction coefficient are very small, and this benefit will not cause any pollution to the environment in which it is used and the parts that need t...
