A bearing remover

Abstract

This utility model provides a bearing dismantling device, comprising: a guide rod; an iron disc, the iron disc being disposed at one end of the guide rod; a sliding hammer, the sliding hammer being slidable along the axial direction of the guide rod for impacting the iron disc; and a semi-enclosed structure, the semi-enclosed structure being disposed at the other end of the guide rod, the inner side of the semi-enclosed structure forming a receiving cavity. This utility model, through the "U"-shaped arrangement of the blocking member, allows the blocking member to form surface contact with the outer wall of the bearing. Compared to the existing dismantling methods using pullers or hammers, where pullers grip the outer wall of the bearing (point contact) and hammers directly strike (also point contact), this device, by forming surface contact between the blocking member and the outer wall of the bearing, allows the bearing to be subjected to force from multiple directions during dismantling, resulting in more even force distribution, improving the efficiency of bearing dismantling, and reducing the risk of damaging the rubber roller, the bearing center hole, or the bearing itself.

Description

Technical Field

[0001] This utility model relates to the technical field of bearing disassembly, and in particular to a bearing disassembly device. Background Technology

[0002] The bearings at both ends of various rubber rollers on the foil making machine need to be removed frequently, so that the bearings can be reworked on the grinding machine. The traditional method of removing the bearings involves using a puller or a hammer, which is time-consuming and laborious, and can easily damage the rubber rollers, the bearing center hole, and the bearing. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a bearing remover.

[0004] This utility model provides the following technical solution: a bearing disassembler, comprising:

[0005] Guide rod;

[0006] Iron disc, the iron disc disposed on one end of the guide rod;

[0007] A sliding hammer, which can slide along the axial direction of the guide rod, is used to strike the iron disc;

[0008] A semi-enclosed structure is provided on the other end of the guide rod, and a receiving cavity is formed inside the semi-enclosed structure. The semi-enclosed structure is used to confine the bearing to be disassembled within the receiving cavity.

[0009] By sliding the hammer to strike the iron disc, a pulling force is applied to the semi-enclosed structure, which in turn causes the semi-enclosed structure to pull the bearing, thus disassembling the bearing.

[0010] Furthermore, the semi-enclosed structure includes:

[0011] A receiving element, which is connected to the end of the guide rod;

[0012] A blocking member, the blocking member being U-shaped, is disposed on the side of the receiving member away from the guide rod; a receiving cavity for restricting the bearing is formed between the receiving member and the blocking member;

[0013] A reinforcing member disposed between the receiving member and the blocking member.

[0014] Furthermore, the receiving member includes a disc portion fixedly connected to the end of the guide rod, and a first arc-shaped portion disposed on the side of the disc portion away from the guide rod;

[0015] The blocking member includes a second arc portion connected to the first arc portion, and two vertical portions extending upward from both ends of the second arc portion;

[0016] The reinforcing member is in a "U" shape and includes a horizontal straight portion and two connecting portions extending from both ends of the horizontal straight portion. The horizontal straight portion is connected to one side of the disc portion close to the guide rod, and the two connecting portions are respectively connected to the two vertical portions.

[0017] Further, a through hole is formed through the sliding hammer, and the sliding hammer is sleeved on the outer wall of the guide rod through the through hole.

[0018] Further, an anti-slip pattern in a grid shape is formed on the outer wall of the sliding hammer.

[0019] Further, the iron disc is welded to one end of the guide rod, and the semi-enclosed structure is welded to the other end of the guide rod.

[0020] Further, the first arc portion is welded to the second arc portion, the two vertical portions are respectively welded to the two connecting portions, and the horizontal straight portion is welded to the disc portion. [[ID=十七]]

[0021] The beneficial effects of this utility model are as follows:

[0022] Through the semi-enclosed structure, finally when the bearing is disassembled, it will directly fall into the semi-enclosed structure, which can avoid the bearing from falling during the disassembly process, thereby damaging the bearing or injuring the staff;

[0023] Through the setting that the blocking member is in a "U" shape, the blocking member can form a surface contact with the outer wall of the bearing. Compared with the disassembly methods of a puller or a hammer in the prior art, the puller grabs the outer wall of the bearing through a gripper, which is a point contact, and the hammer directly hammers also is a point contact. Thus, by forming a surface contact between the blocking member and the outer wall of the bearing, when disassembling the bearing, the bearing can be stressed in multiple directions and the stress is more uniform, improving the efficiency of disassembling the bearing and not easily damaging the rubber roller, damaging the center hole of the bearing and breaking the bearing;

[0024] Through the setting of the reinforcing member, the blocking member can be connected to the disc portion together, thereby improving the firmness of the upper part of the blocking member. During long-term use, the blocking member is not easily damaged, improving the service life of this bearing disassembly tool;

[0025] All components in this bearing disassembly tool are connected by welding. Compared with bearing disassembly tools such as pullers in the prior art, which are connected by threads, the threads are prone to slipping due to impact force during use, resulting in connection failure and inability to use. However, the components in this bearing disassembly tool are connected by welding, which can improve the service life. Description of the Drawings

[0034] This embodiment provides a bearing remover, such as Figure 1 As shown, it includes: guide rod 1, iron plate 3, sliding hammer 2, and semi-enclosed structure 4;

[0035] Guide rod 1

[0036] In this embodiment, as Figure 1 As shown, guide rod 1 is a circular rod with a length of 500 mm and a diameter of 12 mm, and is made of steel;

[0037] Iron plate 3, an iron plate 3 installed on one end of guide rod 1;

[0038] In this embodiment, as Figure 1 As shown, an iron disc 3 is welded to the left end of the guide rod 1. The iron disc 3 is in the shape of a disc, and its axis is on the same straight line as the axis of the guide rod 1. The thickness of the iron disc 3 is 10 mm and its diameter is 45 mm.

[0039] Sliding hammer 2, which can slide along the axial direction of guide rod 1, is used to strike iron disc 3;

[0040] In this embodiment, as Figure 1 and Figure 2 As shown, through holes are formed on both sides of the sliding hammer 2. The sliding hammer 2 is sleeved on the outer wall of the guide rod 1 through the through holes and can slide along the axial direction of the guide rod 1. The sliding hammer 2 is cylindrical and has anti-slip texture in a grid shape on its outer wall so that the operator can push the sliding hammer 2 to slide on the outer wall of the guide rod 1 to hammer the iron plate 3. The diameter of the sliding hammer 2 is 50 mm, the length is 180 mm, and the diameter of the through hole is 13 mm.

[0041] The semi-enclosed structure 4 is provided on the other end of the guide rod 1. The semi-enclosed structure 4 forms a receiving cavity 44 on the inner side of the semi-enclosed structure 4. The semi-enclosed structure 4 is used to restrict the bearing 6 to be disassembled within its receiving cavity 44. By the sliding hammer 2 striking the iron plate 3, a pulling force is applied to the semi-enclosed structure 4, thereby causing the semi-enclosed structure 4 to pull the bearing 6 and disassemble the bearing 6.

[0042] In this embodiment, as Figure 2 As shown, the semi-enclosed structure 4 includes: a receiving member 41, a blocking member 42, and a reinforcing member 43;

[0043] Receiving component 41 is connected to the end of guide rod 1;

[0044] Specifically, such as Figure 3 As shown, the receiving member 41 includes a disc portion 411 fixedly connected to the end of the guide rod 1, and a first arc-shaped portion 412 provided on the side of the disc portion 411 away from the guide rod 1;

[0045] More specifically, the disc portion 411 is welded to the end of the guide rod 1, and the axis of the disc portion 411 is on the same straight line as the axis of the guide rod 1. The disc portion 411 extends outward from the side away from the guide rod 1 to form a semi-circular first arc-shaped portion 412. When the bearing 6 is placed into the receiving cavity 44, the lower outer wall of the bearing 6 contacts the inner wall of the first arc-shaped portion 412. The first arc-shaped portion 412 is located on the lower side of the disc portion 411.

[0046] A blocking member 42, the blocking member 42 is in a "U" shape, and the blocking member 42 is arranged on the side of the receiving member 41 away from the guide rod 1; a receiving cavity 44 for restricting the bearing 6 is formed between the receiving member 41 and the blocking member 42;

[0047] Specifically, as Figure 3 shown, the blocking member 42 includes a second arc portion 421 connected to the first arc portion 412, and two vertical portions 422 extending upward along both ends of the second arc portion 421;

[0048] More specifically, the second arc portion 421 is welded to the side of the first arc portion 412 away from the disc portion 411, and two vertical portions 422 are formed by extending upward along both ends of the second arc portion 421, thereby forming the blocking member 42 into a "U" shape. The thickness of the blocking member 42 is 10 mm, and the width of the middle hollow part is 26 mm; the diameter of the rubber roller 5 is smaller than the width of the middle hollow part of the blocking member 42, so that the rubber roller 5 can enter the middle hollow part of the blocking member 42; the diameter of the bearing 6 is larger than the width of the middle hollow part of the blocking member 42, so that the blocking member 42 blocks the bearing 6 to apply a pulling force to the bearing 6;

[0049] A reinforcing member 43, the reinforcing member 43 is arranged between the receiving member 41 and the blocking member 42;

[0050] Specifically, as Figure 3 shown, the reinforcing member 43 is in a "凵" shape, including a horizontal straight portion 431 and two connecting portions 432 extending from both ends of the horizontal straight portion 43; the horizontal straight portion 431 is connected to the side of the disc portion 411 close to the guide rod 1, and the two connecting portions 432 are respectively connected to the two vertical portions 422;

[0051] More specifically, the horizontal straight portion 431 is welded to the side of the disc portion 411 close to the guide rod 1, the two vertical portions 422 are respectively welded to the two connecting portions 432, and the distance between the two connecting portions 432 is greater than that between the bearings 6, so that the bearing 6 can enter the receiving cavity 44 from between the two connecting portions 432;

[0052] Further explanation: The disc portion 411 forms the left side wall of the semi-surrounding structure 4, the first arc portion 412 forms the lower side wall of the semi-surrounding structure 4, the blocking member 42 forms the right side wall of the semi-surrounding structure 4, the reinforcing member 43 forms the upper side wall of the semi-surrounding structure 4, and the reinforcing member 43 can connect the blocking member 42 and the disc portion 411, thereby increasing the reliability of the upper part of the blocking member 42;

[0053] Working principle: As Figure 4As shown, the operator can first insert the bearing 6 on the rubber roller 5 into the receiving cavity 44 through the gap between the two connecting parts 432. At this time, the lower outer wall of the bearing 6 contacts the inner wall of the first arc-shaped part 412, and the right side wall of the bearing 6 contacts the blocking part 42. Then, the operator can slide the sliding hammer 2 to strike the iron plate 3. The iron plate 3 is struck and a pulling force is generated, which is transmitted to the receiving part 41, the blocking part 42 and the bearing 6 in sequence through the guide rod 1, thereby removing the bearing 6 from the rubber roller 5. Finally, after the bearing 6 is removed, it will fall into the receiving cavity 44 in the semi-enclosed structure 4.

[0054] In summary, by using the semi-enclosed structure 4, the bearing 6 can be disassembled and fall directly into the semi-enclosed structure 4, which can prevent the bearing 6 from falling during the disassembly process and thus damaging the bearing 6 or injuring the staff.

[0055] By using a U-shaped arrangement for the blocking member 42, a surface contact can be formed between the blocking member 42 and the outer wall of the bearing 6. Compared to the existing disassembly methods using a puller or hammer, where the puller grips the outer wall of the bearing 6 (point contact) and the hammer strikes directly (also point contact), the surface contact formed by the blocking member 42 allows the bearing 6 to be subjected to force from multiple directions during disassembly, resulting in more even force distribution, improved disassembly efficiency, and reduced risk of damaging the rubber roller 5, the center hole of the bearing 6, or the bearing 6 itself.

[0056] By providing the reinforcing member 43, the blocking member 42 can be connected to the disc part 411, thereby improving the firmness of the upper part of the blocking member 42. During long-term use, the blocking member 42 is not easily damaged, thus increasing the service life of this bearing remover.

[0057] All components in this bearing remover are welded together. In contrast, existing bearing removers such as pullers use threaded connections, which are prone to stripping under impact during use, leading to connection failure and unusability. The welded connections in this bearing remover improve its service life.
