Description

Technical Field

[0001] This invention relates to the field of motor assembly technology, and more particularly to a motor coupling and bearing disassembly device. Background Technology

[0002] When assembling motor couplings and bearings, couplings are typically fixed and aligned with the shaft using screws, or secured with keyways and clamping mechanisms for a tight fit before assembly. Disassembly is then performed manually by hammering or heating. Bearings are installed using heating or press-fitting methods, and disassembly is also done manually or with heating. These assembly methods can lead to scratches on the shaft and make disassembly difficult. Heating, in particular, can cause uneven stress on the shaft, affecting the performance of the coupling and bearings, and further complicating the disassembly of the motor coupling and bearings.

[0003] Chinese patent CN213005060U discloses a mobile motor coupling disassembly device. This device includes a support frame, a lifting mechanism, and a retractable top pressure head at its output end. Rollers are installed at the bottom of the support frame. The lifting mechanism is mounted on the support frame, and the top pressure head is installed at the output end of the lifting mechanism. The top pressure head is used to press against the motor spindle. A counter-pull mechanism for hooking and pulling the back of the coupling is provided on the outer wall of the top pressure head or on the lifting mechanism. The height of the top pressure head and the counter-pull mechanism are adjusted using the lifting mechanism to adapt to disassembly work of couplings at different installation heights. The cooperation of the top pressure head and the counter-pull mechanism can effectively pull the coupling out of the motor spindle. However, this device requires adjusting the top pressure head and the counter-pull mechanism one by one, resulting in low efficiency. The sequential pressing of the top pressure head against the motor bearing can easily cause damage.

[0004] Therefore, it is necessary to develop a motor coupling and bearing disassembly device to solve the above problems. Utility Model Content

The first transmission component is sleeved on the main shaft and moves along the main shaft. A connecting rod is movably mounted on its outer side, and the outer end of the connecting rod is movably connected to the gripper.

One end of the gripper 23 is placed in the recessed groove 24, and the other end extends along the curve of the main shaft 21, with the end gradually approaching the axis of the main shaft 21.

[0028] Preferably, the end of the gripper 23 extends toward the axis of the main shaft 21 to form a protrusion 26. The outer end of the protrusion 26 is fixedly connected to the gripper 23, and its inner end is close to the axis of the main shaft 21. The outer surface of the protrusion 26 is arc-shaped to facilitate gripping. Furthermore, there are three grippers 23, which are arranged equidistantly around the main shaft 21.

[0029] Please refer to Figures 1 to 2 The drive assembly 3 includes a first drive unit 31, which includes a first drive source 311, a first transmission rod 312 driven by the first drive source 311, and a first transmission component 313 sleeved on the first transmission rod 312. The first drive source 311 is fixedly installed on the fixed plate 22. One end of the first transmission rod 312 is connected to the first drive source 311, and the other end passes through the fixed plate 22 and is connected to the first transmission component 313. The first transmission component 313 includes a movable plate 314 and a connecting rod 315 connected to the movable plate 314. The movable plate 314 is sleeved on the main shaft 21. The shape of the movable plate 314 changes according to the suction. In this embodiment, the movable plate 314 is a cylinder, and its center is sleeved on the main shaft 21. A connecting movable block 316 is provided on the outer side of the movable plate 314. One end of the movable block 316 is fixedly connected to the movable plate 314, and the other end extends radially outward. The position of the movable block 316 corresponds to the position of the gripper 23. The two ends of the connecting rod 315 are connected to the movable block 316 and the gripper 23 respectively through the fixing component 25.

The first drive source 311 drives the gripper 23 away from the main shaft 21 through the first transmission rod 312 and the first transmission component 313. Pulling the handle 12 causes the moving platform 11 to be adjusted to a predetermined position through the moving wheel 13, and the coupling enters between several grippers 23. The first drive source 311 drives the gripper 23 to move in the opposite direction through the first transmission rod 312 and the first transmission component 313. The gripper 23 approaches the main shaft 21 and clamps the coupling. Pulling the handle 12 causes the moving platform 11 to move outward, and the coupling is disengaged from the bearing, completing the disassembly or assembly.

[0033] This utility model is a motor coupling and bearing disassembly device, which has the feature of avoiding damage to the motor. The first drive source drives the gripper to open or close through the first transmission component to clamp the coupling. The moving platform disengages the coupling from the bearing without the need for adjustment of the gripper, thus avoiding contact with the bearing and reducing bearing damage.
