Description

Technical Field

[0001] The invention relates to the technical field of removing an electric wheel bearing sleeve, in particular to a tool and a method for removing an electric wheel bearing sleeve. Background Art

[0002] During the replacement of electric wheel bearings, traditional bearing removal methods usually rely on manual operations, including using a copper rod to knock on the bearing sleeve bit by bit or using a crowbar to pry along the edge. These methods are not only time-consuming, but also pose significant safety hazards. For example, in the process of removing the bearing, two staff members are often required to cooperate: one person is responsible for carefully knocking out the bearing with a crowbar or copper rod, and the other person needs to hold the bearing tightly with both hands to prevent it from accidentally falling, avoiding safety accidents caused by this and possible damage to the bearing.

[0003] In addition, this manual method may also cause injuries to the operator, such as hands being hit by tools or feet being injured by the sudden fall of the bearing. Even if other special bearing removal devices are used, it is difficult to provide effective external protection for the bearing during the removal process, resulting in damage to the bearing surface or internal structure, thereby increasing the risk of the bearing slipping. Therefore, the bearing removal methods in the prior art are not only inefficient, but also have poor safety. A safer, more efficient and effective bearing protection method is urgently needed to solve these problems. Summary of the invention

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0040] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0041] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0042] Example 1

[0043] Reference Figure 1-2 , which is the first embodiment of the present invention, and provides a tool for removing a bearing sleeve of an electric wheel, including a bearing M and an object to be disassembled;

[0044] The driving unit 100 includes a take-out shaft 101, a driving head 102 disposed at the end of the take-out shaft 101, and a limit head 103 disposed at the bottom of the take-out shaft 101;

[0045] The removal shaft 101 includes a driving section 101a disposed at the end of the limiting head 103, and a clamping section 101b disposed at the end of the driving section 101a;

[0046] The driving section 101a drives the inner pulling unit 300 to move along the inside of the bearing M;

[0047] The clamping section 101b limits the outer pull unit 200 to assist the inner pull unit 300 in taking out the bearing M;

[0048] The outer pull unit 200 is hollow inside and can be sleeved with the bearing M.

[0049] It should be noted that the device is used to disassemble and remove the bearing M that is tightly clamped in the bearing sleeve. The diameter of the removal shaft 101 should be much smaller than the inner diameter of the bearing M to ensure that the inner pulling unit 300 connected to the removal shaft 101 can smoothly enter the inner side of the bearing M and move to the bottom of the bearing M.

[0050] Preferably, the removal shaft 101 includes two groups of structures, one of which is a driving section 101a for driving the inner pull unit 300 to remove the bearing M. Under the rotation force, the driving section 101a can make the inner pull unit 300 press against the bottom of the bearing M and slowly pull it out. The other is a clamping section 101b, which limits the outer pull unit 200 at a fixed position to ensure that the clamping section 101b always limits the outer pull unit 200 when the driving section 101a rotates, assisting the inner pull unit 300 to remove the bearing M, providing a supporting force for the inner pull unit 200 to remove the bearing M, and the outer pull unit 200 wraps the bearing M after removal to prevent the bearing M from slipping or the center of the circle from offsetting and hitting the inner structure of the bearing M after removal.

[0051] Preferably, the outer pull unit 200 is sleeved on the outer side of the clamping section 101b and cannot move relative to it. In the process of removing the bearing M, the outer pull unit 200 can be pressed against the bearing sleeve to provide a supporting force for the inner pull unit 300. After the bearing M is removed, the bearing M enters the inner cavity of the outer pull unit 200 to clamp the bearing M and prevent the center of the bearing M from shifting.

[0052] Preferably, the removal shaft 101, the drive head 102, and the stopper head 103 are an integrated structure, all of which are cylindrical. The drive head 102 is in a form that is convenient for manual or mechanical rotation to generate the required rotational torque. The stopper head 103 limits the movement range of the removal shaft 101 to ensure stability during operation.

[0053] Preferably, the removal shaft 101 is made of high-strength alloy steel, and the surface is heat-treated and plated to enhance wear resistance and corrosion resistance. The drive section 101a has a uniform spiral pattern to facilitate the axial movement of the inner pull unit 300 during rotation. The clamping section 101b has multiple grooves or keyways to tightly connect with the outer pull unit 200 to ensure that it will not loosen during the removal process. The drive head 102 is a hexagonal handle or other form that is easy to rotate manually or mechanically, and can be rotated using tools such as a wrench.

[0054] In summary, compared with the traditional manual knocking or prying method, the present device provides continuous and uniform thrust through mechanical means, so that a single person can easily complete the bearing removal work, which significantly improves the work efficiency. Through the cooperation of the inner and outer pull units 300 and the outer pull unit 200, the stability of the bearing M during the removal process is ensured, and the safety accidents caused by the bearing slipping are avoided, while also reducing the risk of injury to the operator.

[0055] Example 2

[0056] Reference Figure 2 to Figure 5 , which is the second embodiment of the present invention, and is different from the first embodiment in that it includes an external pull unit 200, including a connecting plate 201 hinged to the inner side of the clamping section 101b, and supporting columns 202 arranged in a circumferential array at the bottom of the connecting plate 201;

[0057] The inner pull unit 300 can pass through the inner side of the bearing M and be supported on the bottom of the bearing M.

[0058] It should be noted that the connection disk 201 is in the shape of a disk, the center of which is set through the clamping section 101b, and the clamping section 101b hinges and limits the connection disk 201 through the upper and lower baffles. The support column 202 is connected to the bottom of the connection disk 201 by welding or other fixed connection methods. The support column 202 is an arc-shaped plate, and its diameter is consistent with the diameter of the connection disk 201, which can wrap and limit the bearing M after it is taken out.

[0059] Furthermore, the inner pulling unit 300 includes a connecting ring 301 sleeved on the driving section 101a, a plurality of support plates 302 arranged in a circumferential array around the connecting ring 301, a reinforcing plate 303 arranged on the end surface of the support plate 302, and a stopper 304 arranged on the outside of the support plate 302.

[0060] Preferably, the driving section 101a is a screw rod, and the inner side of the connecting ring 301 is a threaded hole, which is threadedly connected to the outer side of the driving section 101a. The outer side of the connecting ring 301 is connected to the support plate 302 by fixed welding or other fixed connection methods. The support plates 302 are arranged in a circular array at the bottom of the connecting ring 301, and the reinforcing plate 303 is welded on the end surface of the support plate 302. The petal-shaped structure of the support plate 302 and the reinforcing plate 303 can improve the pulling rigidity of the support plate 302.

[0061] Preferably, a slot 302a is provided at the end of the support plate 302, into which a stopper 304 can be inserted. The stopper 304 is in the shape of a T-block for easy installation.

[0062] Furthermore, the clamping section 101b includes a slide bar 101b-1, and washers 101b-2 fixedly connected to the upper and lower sides of the slide bar 101b-1;

[0063] The axis of the connecting disk 201 is a circular groove 201a, and is slidably connected to the sliding rod 101b-1;

[0064] The connection plate 201 is restrained on its inner side by the gasket 101b-2.

[0065] It should be noted that the sliding rod 101b-1 is smooth, and two sets of washers 101b-2 are welded at specific positions, and the two sets of washers 101b-2 can clamp the connecting plate 201. The connecting plate 201 has a circular groove 201a extending through the axis thereof, and the connecting plate 201 is hinged to the inner side of the washer 101b-2 through the center of the circle 201a and cannot be displaced, so as to provide a supporting force for the support plate 302 to be pressed against the bottom side of the bearing M during the removal process.

[0066] Further, the support column 202 includes a support platform 202a disposed at the bottom thereof, and a wrapping plate 202b disposed at the top of the support platform 202a;

[0067] The support platform 202a is provided with a positioning hole 202a-1;

[0068] The wrapping plate 202b can wrap the bearing M.

[0069] Furthermore, a slot 302a is provided at the end of the support plate 302;

[0070] The diameter of the support plate 302 is smaller than the diameter of the bearing M;

[0071] The diameter of the stopper 304 after being plugged into the slot 302a is larger than the diameter of the bearing M, and can be supported on the bottom of the bearing M.

[0072] It should be noted that the wrapping plate 202b is welded to the bottom of the connecting plate 201, and the bottom of the wrapping plate 202b is also on the support platform 202a. A positioning hole 202a-1 is provided on the surface of the support platform 202a, and the positioning hole 202a-1 can be connected to the flange hole on the outer bearing sleeve of the bearing M by bolts to ensure the stability of the bearing M during the removal process.

[0073] Preferably, each set of support plates 302 has a slot 302a at its end face, and the stopper 304 is a T-shaped block, which can be connected together by plugging, and the arm length of the support plate 302 can be extended. When the bearing M is taken out, the stopper 304 is not plugged into the slot 302a, and the length of the support plate 302 is smaller than the inner diameter of the bearing M. The driving section 101a is rotated to drive the connecting ring 301 and the support plate 302 to the bottom position of the bearing M, and then the stopper 304 is plugged into the slot 302a to intercept the support plate 302 at the bottom of the bearing M; then the driving section 101a is reversed, the connecting ring 301 and the support plate 302 are retracted, and the bearing M is ejected. During the ejection process of the bearing M, the support platform 202a is supported at the end of the bearing sleeve, and the bearing M is continuously wrapped by the wrapping plate 202b, which fixes it in the wrapping plate 202b to prevent the bearing M from slipping.

[0074] Furthermore, the limiting head 103 includes a threaded end 103a, a nut 103b disposed on the threaded end 103a, and a gasket 103c disposed inside the nut 103b.

[0075] Furthermore, the diameter of the threaded end 103 a is smaller than the diameter of the removal shaft 101 .

[0076] Furthermore, the driving head 102 includes a rotating rod 102a disposed at the end of the sliding rod 101b-1, and a sleeve shaft end 102b disposed at the end of the rotating rod 102a.

[0077] Preferably, the diameter of the threaded end 103a is smaller than the diameter of the removal shaft 101, so as to ensure that the limit head 103 can smoothly pass through the inner side of the bearing M and will not interfere with the bearing M during operation. The nut 103b is arranged on the threaded end 103a and is made of high-strength material to ensure a firm connection between the limit head 103 and the removal shaft 101. The nut 103b can be tightened or loosened by tools such as a wrench, which is convenient for disassembly and maintenance. The gasket 103c is arranged on the inner side of the nut 103b to reduce shock and disperse pressure, prevent the nut 103b from loosening due to long-term use, and reduce wear and extend the service life.

[0078] The rotating rod 102a is disposed at the end of the sliding rod 101b-1 and is used to transmit the rotation torque. The design of the rotating rod 102a enables it to be used in conjunction with various manual or mechanical rotating tools such as a wrench to generate the required rotation force.

[0079] The sleeve shaft end 102b is arranged at the end of the rotating rod 102a, and is designed to be hexagonal or other forms that are convenient for manual or mechanical rotation. The sleeve shaft end 102b can be rotated using a tool such as a wrench, thereby driving the entire removal shaft 101 to rotate and pushing the inner pull unit 300 to move along the inside of the bearing M.

[0080] When in use, the inner pull unit 300 is placed inside the bearing M, and the drive section 101a of the removal shaft 101 is inserted into the inner pull unit 300, so that the inner pull unit 300 can move to the bottom of the bearing M with the removal shaft 101. Insert the stopper 304 into the slot 302a and press it against the bottom of the bearing M. Adjust the position of the outer pull unit 200 so that it presses against the bearing sleeve to provide a stable supporting force for the inner pull unit 300. Use a wrench or other tool to clamp the sleeve shaft end 102b of the drive head 102 and start rotating. The drive section 101a of the removal shaft 101 will push the inner pull unit 300 to move outward along the inside of the bearing M, thereby gradually pulling the bearing M out of its position until the bearing M is completely out of place. At this time, the bearing M enters the inner cavity of the outer pull unit 200 and is wrapped by the outer pull unit 200 to prevent the bearing M from slipping or the center of the circle from shifting.

[0081] In summary, compared with the traditional manual knocking or prying method, this tool provides continuous and uniform thrust through mechanical means, so that a single person can easily complete the removal of the bearing, which significantly improves work efficiency. Through the cooperation of the inner pull unit 300 and the outer pull unit 200, the stability of the bearing M during the removal process is ensured, safety accidents caused by the bearing slipping are avoided, and the risk of injury to the operator is also reduced. Local overpressure on the inner wall of the bearing is avoided, which effectively prevents damage to the bearing during the removal process and extends the service life of the bearing.

[0082] Example 3

[0083] This is the third embodiment of the present invention, which is different from the first two embodiments in that it also includes a method for removing a tool for an electric wheel bearing sleeve, specifically:

[0084] Place the inner pull unit 300 into the bearing M to be disassembled, and enable it to expand on the outside to fix the bearing M;

[0085] Positioning and fixing the outer pull unit 200 to provide stable support for the inner pull unit 300;

[0086] By operating the driving unit 100, the removal shaft 101 generates an axial thrust, thereby pushing the inner pulling unit 300 to drive the bearing M to move outward;

[0087] Continue to apply the thrust until the bearing M is completely removed from the mounting position and wrapped by the wrapping plate 202b.

[0088] It should be noted that the inner pull unit 300 is placed inside the bearing M to be disassembled, and is able to expand outside to fix the bearing M and insert the stopper 304 into the slot 302a at the end of the support plate 302. In this way, the support plate 302 will expand at the bottom of the bearing M and firmly grasp the bearing M.

[0089] Position and fix the outer pull unit 200 to provide stable support for the inner pull unit 300. Install the outer pull unit 200 to a suitable position. The outer pull unit 200 includes a connecting plate 201 and a support column 202. The connecting plate 201 is slidably connected to the clamping section 101b of the removal shaft 101 through a circular groove 201a and is limited by a washer 101b2. Adjust the position of the outer pull unit 200 so that it rests on the bearing sleeve to ensure that it does not move during operation. If necessary, the outer pull unit 200 can be fixed to the bearing sleeve using bolts through the positioning holes 202a1 on the support platform 202a.

[0090] By operating the driving unit 100, the removal shaft 101 generates an axial thrust, thereby pushing the inner pull unit 300 to drive the bearing M to move outward. Use a wrench or other tools to clamp the sleeve shaft end 102b of the driving head 102 and start rotating. The driving head 102 includes a rotating rod 102a and a sleeve shaft end 102b. As the driving head 102 rotates, the driving section 101a of the removal shaft 101 will push the inner pull unit 300 to move outward along the inside of the bearing M. Since the inner pull unit 300 has been fixed to the bottom of the bearing M by the stopper 304, the inner pull unit 300 will drive the bearing M to move outward together.

[0091] Continue to apply thrust until the bearing M is completely removed from the installation position and wrapped by the wrapping plate 202b. Continue to rotate the drive head 102 until the bearing M is completely out of position. At this time, the bearing M will be wrapped by the wrapping plate 202b of the outer pull unit 200 to prevent it from slipping or center deviation. When the bearing M is completely removed, carefully remove the tool, check whether the bearing M is intact, and further process or replace it.

[0092] It is important to note that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
