Abstract: PURPOSE: An air foil bearing with a divided structure is provided to easily assemble and disassemble the air foil bearing to/from a rotary shaft and to reduce costs for maintenance and repair by disassembling only the air foil bearing without disassembling an impeller or a blade when replacing the air foil bearing from the rotary shaft. CONSTITUTION: An air foil bearing with a divided structure comprises a top foil(10), a bump foil(20), a first housing unit(30), and a second housing unit(40). The top foil surrounds a rotary shaft and forms an air layer between the rotary shaft and the top foil when rotating the rotary shaft so that the rotary shaft rises. The top foil includes a fixing unit. The bump foil surrounds the top foil and reduces the vibration of the rotary shaft. The first housing unit covers a part of the bump foil and includes a fixing groove where the fixing unit is received. The second housing unit covers the other part of the bump foil and pressurizes the fixing unit when joining to the first housing unit so that the top foil is fixed.
