2. The utility model discloses rotor bearing dismantles frock, according to the length of dismantling rotor bearing, adjustable U type bracket is apart from the base height, and adjusting position back both sides insert fixing bolt, make tip and bracing piece surface contact through rotatory fixing bolt, extrude mutually with the bracing piece through both ends fixing bolt, realize fixed locking completely.

3. The utility model discloses rotor bearing dismantles frock, dismantles the bearing and need make the bearing break away from through hitting the axle, therefore U type bracket still is equipped with the balancing weight, through the external force of knocking and demolish the bearing and decide to increase an amount of balancing weight, offsets the power of hitting the axle, prevents that the frock from inclining and damaging.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Embodiment 1, as shown in fig. 1, a rotor bearing dismounting tool includes a base 1, a support rod 2 is arranged on the base 1, a U-shaped bracket 3 is arranged on the support rod 2, and the U-shaped bracket 3 is provided with a clamping groove 31; the U-shaped bracket 3 comprises a front support 32 and a rear support 33 which are integrally formed, the clamping groove 31 is formed in the front support 32, a supporting rod mounting hole 331 is formed in the rear support 33, and the supporting rod mounting hole 331 is formed in the supporting rod 2. The clamping groove 31 is used for placing a rotor bearing to be disassembled. The front tray 32 is shorter in height than the rear tray 33.
