Description

Technical Field [0001] The present invention relates to a metal mesh bearing damper device,

The present invention relates to a metal mesh bearing damper manufacturing apparatus, and more particularly, to an apparatus for manufacturing a damper of a bearing capable of simultaneously acting as a thrust bearing and a radial bearing by using a metal press- It is possible to provide a damper having a constant density occupied by a metal mesh in accordance with the volume of a damper assembly part as well as maintaining a circular state by absorbing the shock of the rotating body and having a durability sufficient to withstand the axial load, It is possible to easily and quickly manufacture the damper of the metal mesh material according to the size and density, thereby saving manpower and physical time, and it is possible to provide a damper having a metal mesh To a bearing damper manufacturing apparatus.

In the case of a high-speed rotating body, it is required to have a damping effect of vibration generated at a high-speed rotation, and it must not only be used at a high temperature but also requires durability so as to prevent bearing damage due to axial load. There is a growing demand for contactless oil-free thrust bearings.

Various noncontact oil-less bearing technologies have been proposed according to the above requirements, and airfoil bearings and electromagnet bearings are representative examples.

In the case of an airfoil bearing, it is proposed in Korean Patent No. 1204194 entitled " Gas Foil Thrust Bearing and Centrifugal Compressor Including It ", and in the case of an electromagnet bearing, it is proposed in US Patent Publication No. 2009-0039740 "Magnetic Bearing ".

However, since the thrust bearing is different from the radial bearing in which the supporting direction is the axial direction and the supporting direction is the radial direction, the thrust bearing and the radial bearing are constituted by separate systems.

Since the two bearings must be fabricated and assembled separately, a separate backstroke bearing backplate is required, which complicates the process and requires procedures to assure assembly accuracy during assembly.

In addition, the airfoil thrust bearing applied to the thrust bearing has a problem that the limit of the axial load is very small.

In addition, there is a need for a fabrication process that requires the use of tricky bump shapes and thrust foils and bumps to the bearing housing.

That is, the thrust bearing and the radial bearing are constituted by a separate system, which causes a problem that the volume of the bearing portion must be increased.

Particularly, in the case of the small rotating body including the compressor turbine impeller, since the volume becomes large when the radial bearing and the thrust bearing are applied, it is necessary to construct the thrust bearing in the back plate portion of the turbine or the impeller in order to increase the first bending mode There is no problem.

Although the necessity of using a bearing using a metal mesh damper is increasing due to the above problems, a systematic method for manufacturing a metal mesh damper is not established and many problems arise.

Particularly, in the process of compressing the metal mesh to control the density, the metal mesh is not torn or the density is not uniformly generated, and the shape of the damper is deformed in the process of removing the compressed damper, Is different from the design dimension.

Further, there is a problem that it is difficult to easily adjust the thickness of a damper to be manufactured.
