BEARING DECOMPOSING DEVICE

PROBLEM TO BE SOLVED: To easily perform bearing change providing a chuck to be brought into contact with the inner peripheral surface of a bearing by the operation of a handle and for holding the bearing bottom part. SOLUTION: In this bearing decomposing device, each one end of hydraulic rams 3 are installed on a fixed body 2 in which a bearing 1 is inserted, and an upper base 4 is fastened to the other ends of the hydraulic rams 3. A hinge 5 is brought into rotatable-contact with the upper base 4, and one end of a shaft 6 is connected to the hinge 5. The bearing decomposing device is constituted of a downward inclined surface guide cam 7 having a downward-inclined surface on the other end of the shaft 6, an upward inclined surface guide cam 8 installed above the downward inclined surface guide cam 1 and having an upward inclined surface, and a chuck 9 having the same inclination as the downward inclined surface guide cam 7 and the upward inclined surface guide cam 8. Therefore, bearing replacing work can be easily performed without distorting the bearing.
