(1) bearing outer ring disassembly
Referring to fig. 7, the bearing block 5 is installed at the central hole position of the upper housing 6; mounting the spring 16 at an inner position of the slider 14;
releasing the three sliding blocks 14, driving the claw arms 10 to move outwards under the action of the springs 16, enabling the three claw teeth 11 to abut against the bearing holes of the gearbox shell to tightly buckle the edge of the outer ring of the bearing, and automatically correcting the tool due to the balance action of the springs 16 almost without eccentricity;
the driving screw rod 1 is driven to move downwards by using power tools such as an air gun and the like, and is driven continuously after being abutted against the upper part of the bearing block 5, and at the moment, the bearing block 5, the upper shell 6 and the lower shell 9 are matched with each other to play a role in supporting the driving screw rod 1 in the center.
And (3) continuing driving, wherein the upper pull disc 2 moves upwards due to the continuous driving of the driving screw rod 1, the track pull disc 7 is driven to move upwards under the transmission action of the pull rod 4, then the movement is transmitted to the claw arm 10 and the claw tooth 11, and the outer ring of the bearing gradually moves under the action of force, is separated from the mounting hole and is detached.
(2) Bearing outer ring installation
Replacing the tooling claw teeth 11 with larger claw teeth, and replacing the lower shell 9 with the diameter consistent with that of the bearing outer ring;
sleeving the outer ring of the bearing on the three claw arms 10, extending the claw teeth 11 into the wall of the shell of the gearbox, and tightly buckling the claw teeth on the shell of the gearbox;
the driving screw 1 is driven, the driving screw 1 is driven to move downwards by using power tools such as an air gun and the like, the driving screw 1 is continuously driven after being abutted to the upper part of the bearing block 5, at the moment, the moving parts are the driving screw 1, the bearing block 5, the upper shell 6 and the lower shell 9, the lower shell 9 pushes the outer ring of the bearing to gradually move to a required position, and the installation is completed.
(3) Change the mode of operation
Removing the bearing block, adjusting the direction of the claw teeth 11 to turn to the inner side, and installing a spring 16 on the outer side of the spring guide rod 13;
at the moment, the upper shell 6 and the lower shell 9 do not participate in the working process and can be detached as appropriate, and the state of the tool is converted into a common three-jaw chuck tool mode and can be used for detaching parts such as a bearing inner ring and a gear which are arranged on a shaft. Due to the existence of the structures such as the sliding block 14 and the spring 16, the safety of the chuck is better than that of a common chuck, and the upper shell 6 can play a role in protection if not detached, so that part of flying objects when parts are damaged can be blocked.
The claw arm 10 and the claw teeth 11 are tightly buckled and arranged on the side surface of a bearing inner ring (or a gear) on the shaft, and the driving screw rod 1 is driven to penetrate through a central hole of the track pull disc 7 until the lower end of the driving screw rod is abutted against the shaft;
and continuously driving the driving screw rod 1 to gradually separate the bearing inner ring from the shaft, and finishing the disassembly.
