Title:
DYNAMIC PRESSURE BEARING AND MANUFACTURE THEREOF
Document Type and Number:
Japanese Patent JPH08196056
Kind Code:
A
Abstract:
PURPOSE: To form a dynamic pressure plane and a dynamic pressure generation groove efficiently at a predetermined accuracy.
CONSTITUTION: A shaft body 21 and a shaft fitting body 31 constituting a dynamic pressure plane are made of aluminum or an alloy thereof excellent in machinability. Both the dynamic pressure planes 21, 31 and a dynamic pressure generating groove 25 are formed by cutting using a same cutting machine without requiring any mounting/demounting. With such method, both the dynamic pressure planes 21, 31 and the dynamic pressure generating groove 25 can be formed well without decrease of the machining accuracy.
