Hydrostatic Support Design of Cooling Copper Roller with Inner Pressure Feedback in Forming Amorphous Ribbon

Abstract:

Cooling copper roller is the key technology and equipment to amorphous ribbon forming. Rolling bearing support is difficult to obtain high rotation accuracy. A new inner pressure feedback hydrostatic journal bearing is proposed with different recess area. The load capacity and film stiffness mathematical model of hydrostatic journal bearing are established. The Inner pressure feedback hydrostatic journal bearing with different recess area at the diameter of 200mm is designed and manufactured for amorphous ribbon cooling copper roller support structure. The operation tests demonstrate that the rotation accuracy of the cooling copper roller shaft is less than 2μm, which in accordance with the requirements of amorphous ribbon production process.
