AIRFOIL JOUNAL BEARING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18091841 titled 'AIRFOIL JOUNAL BEARING
Simplified Explanation
The abstract describes an airfoil journal bearing design for a rotation shaft. The bearing housing has a hollow inner surface where the rotation shaft can be inserted. The airfoil is positioned in the hollow, enclosing a significant portion of the rotation shaft's circumference. A ring member encloses the outer surface of the bearing housing. The bearing housing has an insert slit that extends from the inner surface to the outer surface. The airfoil has an insert part that is bent from the circumferential direction to the radial direction of the bearing housing, extending through the insert slit to the outer surface. The airfoil is engaged with the outer surface of the ring member through the insert part.
- The airfoil journal bearing design encloses a large portion of the rotation shaft's circumference, providing enhanced stability and support.
- The insert slit and insert part allow for easy installation and engagement of the airfoil with the ring member.
- The design simplifies the construction and assembly of the bearing, potentially reducing manufacturing costs.
Potential Applications
- This airfoil journal bearing design can be used in various rotating machinery applications, such as turbines, engines, and pumps.
- It can be particularly beneficial in high-speed applications where stability and support are crucial.
Problems Solved
- The design solves the problem of inadequate stability and support in traditional journal bearings by enclosing a larger portion of the rotation shaft's circumference.
- It also addresses the challenge of complex assembly and installation by incorporating the insert slit and insert part.
Benefits
- Enhanced stability and support for the rotation shaft, reducing the risk of vibration and damage.
- Simplified construction and assembly process, potentially reducing manufacturing costs.
- Improved performance and reliability in high-speed rotating machinery.
Original Abstract Submitted
An airfoil journal bearing including a bearing housing having an inner surface forming a hollow so that a rotation shaft is insertable in the hollow; an airfoil in the hollow so that, when the rotation shaft is inserted in the hollow, the airfoil encloses at least 180 to 360 degrees of a circumference of the rotation shaft; and a ring member enclosing an outer surface of the bearing housing. The bearing housing includes an insert slit formed through the bearing housing from the inner surface of the bearing housing to the outer surface of the bearing housing. The airfoil includes an insert part bent from a circumferential direction of the airfoil to a radial direction of the bearing housing and extending, through the insert slit, to the outer surface of the bearing housing. The airfoil is engaged with an outer surface of the ring member through the insert part.
