<P>PROBLEM TO BE SOLVED: To provide a press-fitting device that enables smooth press fitting with high accuracy by preventing burrs or galling. <P>SOLUTION: The press-fitting device includes a pushing mechanism 10 pushing a bearing assembly 5 to a press-fitting part of a crankshaft 2, and a driving mechanism 11 applying a pushing force to the pushing mechanism 10. The pushing mechanism 10 includes a first pushing jig 12 to be brought into contact with the bearing assembly 5, and a second pushing jig 13 in contact with the first pushing jig 12 to transmit a pushing force received from the driving mechanism 11 to the first pushing jig 12. The first pushing jig 12 is configured to come in contact with a bearing assembly 5, while being inclined toward the second pushing jig 13. Partially spherical surfaces 19, 20 to be brought into contact with each other are arranged in the first pushing jig 12 and the second pushing jig 13, respectively. The second pushing jig 13 can slide relative to the driving mechanism 11 in a direction crossing the pushing force. <P>COPYRIGHT: (C)2012,JPO&INPIT |
