[0002] In the field of machinery, bearings are key components, and their maintenance and replacement often require precise and efficient operations. Among them, removing the inner ring of the bearing is a challenging task. Existing bearing inner ring removal tools are relatively simple, generally using a gripping structure that combines multi-point elastic fitting with toothed bite. The structure is relatively complex and difficult to disassemble. Workers need to undergo complex training and learning when disassembling. In addition, the inner ring is prone to slipping during the disassembly process, making it more difficult to remove the inner ring that falls into the equipment, and even affecting the operation of the equipment. Summary of the invention

[0003] The purpose of the present invention is to provide a stable and reliable bearing inner ring removal tool to solve the problem that the bearing inner ring is difficult to remove in the prior art and the inner ring is prone to slipping during the removal process.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A stable and reliable bearing inner ring removal tool comprises an adjusting screw, a fixing seat, a connecting rod and a semicircular locking ring, wherein two semicircular locking rings are provided and the two semicircular locking rings cooperate to form a sleeve hole, the sleeve hole is sleeved on the outside of the bearing inner ring and is in frictional contact with the bearing inner ring; the two semicircular locking rings are respectively connected to the lower part of a connecting rod, and the upper parts of the two connecting rods are connected to the fixing seat; the diameter of the adjusting screw is smaller than the inner diameter of the sleeve hole, the adjusting screw is provided above the sleeve hole, and the middle part of the adjusting screw is threadedly connected to the fixing seat.

[0006] As a preferred technical solution in the present invention, the adjusting screw is coaxially arranged with the sleeve hole.

[0007] As a preferred technical solution in the present invention, the lower parts of the two connecting rods are threadedly connected to the corresponding semicircular locking rings.

[0008] As a preferred technical solution in the present invention, the connecting rod is a vertically arranged threaded rod, and the upper part of the connecting rod is threadedly connected to the fixing seat.

[0009] As a preferred technical solution in the present invention, two locking nuts are threadedly connected to each connecting rod, and the two locking nuts are clamped at the upper and lower ends of the fixing seat.

[0010] As a preferred technical solution in the present invention, a positioning nut is fixed to the upper end of the middle part of the fixing seat, and the middle part of the adjusting screw is threadedly connected to the positioning nut.

[0011] As a preferred technical solution in the present invention, the upper end of the adjusting screw is threadedly connected with a holding nut.

[0012] As a preferred technical solution in the present invention, the semicircular locking ring is supported by an alloy material, and the surface of the semicircular locking ring is provided with an anti-rust layer and an anti-corrosion layer.

[0013] Beneficial effect: When the present invention is operated, firstly two semicircular locking rings are used to be sleeved on the inner ring of the bearing outside the cylinder, and then the lower end of the adjusting screw is used to press against the upper end of the cylinder, and the adjusting screw is rotated downwardly. When the inner ring of the bearing and the semicircular locking ring do not rotate, the fixing seat can be moved vertically upward relative to the adjusting screw, and then the two semicircular locking rings are driven to move vertically upward through the connecting rod. The two semicircular locking rings simultaneously drive the inner ring of the bearing to move vertically up and down until the inner ring of the bearing is removed from above the cylinder. The operation of the present invention is simple. Compared with the prior art, the inner ring of the bearing is clamped by two semicircular locking rings, which can more effectively prevent the inner ring of the bearing from slipping on the basis of relatively protecting the inner ring structure of the bearing, thereby improving the protection rate of the inner ring of the bearing for reuse. Moreover, the whole process only requires rotating the adjusting screw, which is simple and easy to learn, reduces the difficulty of disassembly, shortens the maintenance time, and thereby improves the production efficiency.

[0017] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0018] Example:

[0019] like Figure 1 and Figure 2As shown, this embodiment provides a stable and reliable bearing inner ring removal tool, including an adjusting screw 1, a fixing seat 2, a connecting rod 3 and a semicircular locking ring 4, wherein two semicircular locking rings 4 are provided, and when the two semicircular locking rings 4 are assembled, the two semicircular locking rings 4 cooperate to form a sleeve hole, and the sleeve hole is sleeved on the outside of the bearing inner ring and in friction contact with the bearing inner ring, so that the two semicircular locking rings 4 can clamp the bearing inner ring under normal circumstances without rotating relative to the bearing inner ring; the two semicircular locking rings 4 are each connected to the lower part of a connecting rod 3, and the upper parts of the two connecting rods 3 are connected to the fixing seat 2, so that the semicircular locking ring 4 is stably connected to the fixing seat 2 through the connecting rod 3; the diameter of the adjusting screw 1 is smaller than the inner diameter of the sleeve hole, and can pass through the inner ring of the bearing for operation. The adjusting screw 1 is arranged above the sleeve hole, which does not affect the two semicircular locking rings 4 being sleeved outside the inner ring of the bearing, and the middle part of the adjusting screw 1 is threadedly connected to the fixing seat 2, which is convenient for adjusting the relative position of the adjusting screw 1 on the fixing seat 2.

[0020] It should be noted that, preferably, a support plate can be provided at the lower end of the two semicircular locking rings 4, and then when the two semicircular locking rings 4 are sleeved on the outside of the bearing inner ring, the support plate can be used to abut the lower end of the bearing inner ring, thereby making it easier for the semicircular locking ring 4 to drive the bearing inner ring to realize the disassembly operation.

[0021] When the present invention is operated, two semicircular locking rings 4 are firstly used to be sleeved on the inner ring of the bearing outside the cylinder, and then the lower end of the adjusting screw 1 is used to press against the upper end of the cylinder, and the adjusting screw 1 is rotated downwardly. When the inner ring of the bearing and the semicircular locking ring 4 do not rotate, the fixing seat 2 can be moved vertically upward relative to the adjusting screw 1, and then the two semicircular locking rings 4 are driven to move vertically upward through the connecting rod 3. The two semicircular locking rings 4 simultaneously drive the inner ring of the bearing to move vertically up and down until the inner ring of the bearing is removed from the top of the cylinder. The operation of the present invention is simple. Compared with the prior art, the inner ring of the bearing is clamped by two semicircular locking rings 4, which can more effectively prevent the inner ring of the bearing from slipping on the basis of relatively protecting the inner ring structure of the bearing, thereby improving the protection rate of the inner ring of the bearing for reuse, and the whole process only needs to rotate the adjusting screw 1, which is simple and easy to learn, reduces the difficulty of disassembly, shortens the maintenance time, and thereby improves the production efficiency.

[0022] As a preferred implementation scheme in this embodiment, it needs to be further explained that the adjusting screw 1 is coaxially arranged with the sleeve hole, so that while the adjusting screw 1 can pass through the inner ring of the bearing, the thickness of the adjusting screw 1 can be controlled as much as possible, thereby ensuring that the adjusting screw 1 has sufficient strength.

[0023] As a preferred implementation scheme in this embodiment, it needs to be further explained that the lower parts of the two connecting rods 3 are threadedly connected to the corresponding semicircular locking rings 4, and different semicircular locking rings 4 can be selected according to actual conditions to adapt to bearing inner rings of different sizes and improve applicability.

[0024] As a preferred implementation scheme in this embodiment, it needs to be further explained that the connecting rod 3 is a vertically arranged threaded rod, and the upper part of the connecting rod 3 is threadedly connected to the fixing seat 2, so that the spacing between the fixing seat 2 and the semicircular locking ring 4 can be adjusted according to actual conditions, so as to adapt to the disassembly work of the bearing when it is installed in different positions on the cylinder. At the same time, the detachable connection method of the connecting rod 3 can solve some problems that are difficult to disassemble due to space limitations, such as avoiding obstacles such as transmission parts, and can still successfully complete the disassembly work under limited space conditions, which increases the applicable scenarios and flexibility of the technology.

[0025] As a preferred implementation scheme in this embodiment, it needs to be further explained that each connecting rod 3 is threadedly connected to two locking nuts 5, and the two locking nuts 5 are clamped at the upper and lower ends of the fixing seat 2 to ensure that the connecting rod 3 and the fixing seat 2 are relatively fixed and there is no relative movement between the two.

[0026] As a preferred implementation scheme in this embodiment, it needs to be further explained that a positioning nut 6 is fixed to the upper end of the middle part of the fixing seat 2 , and the middle part of the adjusting screw 1 is threadedly connected to the positioning nut 6 .

[0027] As a preferred implementation scheme in this embodiment, it needs to be further explained that the upper end of the adjusting screw 1 is threadedly connected with a holding nut 7, so that the adjusting screw 1 can be conveniently controlled to rotate by holding the holding nut 7 by hand.

[0028] As a preferred implementation scheme in this embodiment, it needs to be further explained that the semicircular locking ring 4 is supported by an alloy material, which ensures durability and deformation resistance during use. The surface of the semicircular locking ring 4 is provided with an anti-rust layer and an anti-corrosion layer, which can work reliably for a long time under harsh conditions, reducing the frequency of maintenance and replacement and reducing costs.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
