[0002] Couplings and bearings, as core components of power transmission systems, are crucial for ensuring the stable operation of factory equipment.

[0003] However, in actual production, the couplings and bearings of large motors face significant technical challenges during maintenance: due to their special structural design, high precision requirements, and the tendency to develop interference fits after long-term operation, disassembly is extremely difficult, which greatly prolongs equipment maintenance time. Therefore, this solution proposes a bearing puller to solve the above problems. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This utility model provides, for example Figure 1-4 The bearing puller shown includes:

[0031] Circular plate 1;

[0032] Fixing plate 2 is set on one side of circular plate 1, and locking components 6 are symmetrically arranged on both sides of fixing plate 2;

[0033] Connecting component 3 is disposed on the side opposite to the circular plate 1 and the fixed plate 2. Connecting component 3 is used to fix the circular plate 1 and the fixed plate 2.

[0034] Jack 4 is fixedly connected to one side of the circular plate 1;

[0035] Limiting component 5 is fixedly connected to the output end of jack 4. Limiting component 5 is used to connect the bearing and jack 4.

[0036] It should be noted that the electric jack 4 is an existing device. In use, it is driven by an electric motor to rotate. After the torque is increased by the reduction mechanism, the transmission device is driven to convert the rotational motion into linear lifting motion. When the motor rotates forward, the screw extends and when it rotates in reverse, it slowly retracts, thereby moving the limiting component 5 at its output end. There are two fixed plates 2. The fixed plates 2 are fixed to the motor shaft by the locking component 6. The limiting component 5 is connected to the jack 4 and the bearing. The circular plate 1 and the fixed plate 2 are fixed by the connecting component 3. In use, the jack 4 directly moves the limiting component 5 and the bearing, and the jack 4 also drives the bearing to separate from the motor shaft, avoiding the situation where it is difficult to separate the bearing from the motor shaft.

[0037] Specifically, connection component 3 includes:

[0038] Connecting rod 301 is fixedly connected to one side of circular plate 1;

[0039] Threaded rod 302 is fixedly connected to one end of connecting rod 301;

[0040] The first nut 303 is threaded onto the middle part of the threaded rod 302.

[0041] Specifically, a positioning groove 201 is provided at the bottom of the fixing plate 2, and the horizontal longitudinal section of the positioning groove 201 is set as a semi-circle.

[0042] Specifically, a positioning hole 202 is provided in the middle of the fixing plate 2, and the threaded rod 302 is inserted and connected inside the positioning hole 202.

[0043] It should be noted that there are two connecting rods 301. Each connecting rod 301 has a threaded rod 302 fixedly connected to its end. The diameter of the positioning hole 202 is smaller than the diameter of the connecting rod 301, so that the connecting rod 301 cannot pass through the positioning hole 202. When it is necessary to fix the circular plate 1 and the fixed plate 2, first align the threaded rod 302 on one side of the circular plate 1 with the positioning hole 202 on the fixed plate 2, then pass the threaded rod 302 through the positioning hole 202, so that the connecting rod 301 is connected to one side of the fixed plate 2, and finally thread the first nut 303 onto the threaded rod 302, thereby fixing the fixed plate 2 and the connecting rod 301.

[0044] Specifically, locking component 6 includes:

[0045] The fixing cylinder 602 is fixedly connected to one side of the fixing plate 2;

[0046] Bolt 601 is inserted and connected to the middle of the fixed cylinder 602;

[0047] The second nut 603 is threaded onto one end of the bolt 601.

[0048] It should be noted that there are two fixing plates 2. Each fixing plate 2 has a fixing cylinder 602 fixedly connected to both sides. When it is necessary to fix the fixing plate 2 to the motor shaft, first put both fixing plates 2 on the motor shaft, align the fixing cylinders 602 on the two fixing plates 2, and finally pass the bolts 601 through the aligned fixing cylinders 602 in sequence, and fix the two fixing plates 2 with the second nut 603, so that the two fixing plates 2 are fixed to the motor shaft.

[0049] Specifically, the limiting component 5 includes a connecting plate 501 fixedly connected to the output end of the jack 4, an arc-shaped plate 502 fixedly connected to one side of the connecting plate 501, and a pulling plate 503 fixedly connected to one side of the arc-shaped plate 502.

[0050] It should be noted that the connecting plate 501 is used to connect the arc plate 502 and the output end of the jack 4. The top of the pulling plate 503 is provided with an arc groove that matches the motor shaft. In use, the circular plate 1 drives the limiting component 5 to move, so that the arc plate 502 is sleeved on the outer wall of the bearing or coupling, so that the bearing or coupling is located between the connecting plate 501 and the pulling plate 503, and the pulling plate 503 is sleeved on the motor shaft through the arc groove. Then, the jack 4 drives the limiting component 5 to move, and the pulling plate 503 drives the bearing or coupling to move away from the motor shaft, thereby completing the separation of the bearing or coupling from the motor shaft.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
