Description

Technical Field

[0001] This utility model relates to the field of bearing disassembly tooling technology, and in particular to a special tooling for disassembling the outer ring of the differential tapered bearing of a new energy reducer. Background Technology

[0002] Generally, bearing disassembly fixtures refer to the fixtures used to remove scrapped bearings from the equipment. If the main shaft is scrapped, the bearing on it must also be replaced. This is because the bearing and the main shaft are assembled using a hot-fitting method, which means they are hammered in by heating. When removing them, they need to be heated and hammered again. As a result, the performance of the bearing is damaged and it is no longer suitable for use. Of course, in actual operation, in order to save working time, the bearing may be cut off directly. In this way, a perfectly good bearing is scrapped, resulting in waste and greatly increasing construction costs.

[0003] Existing bearing disassembly fixtures are space-consuming and difficult to carry, and require considerable effort to use. Each fixture can only disassemble one type of bearing and lacks expandability, which makes them unsuitable for users' needs and increases the cost of use. On the other hand, existing fixtures are weak in fixing the position of the device, so the manpower required for use increases.

[0004] Chinese utility model patent application (publication number CN209520840U) discloses a bearing outer ring disassembly tool. Although the bearing outer ring disassembly tool has a simple structure and can disassemble the bearing outer ring, it is only applicable to the case where the bearing ring hole below the pump structure is a through hole, and is not applicable to the case where the bearing ring hole below the solid plane. Its scope of application is narrow, and it is not applicable to the disassembly of bearing outer rings with different hole diameters.

[0005] To address this issue, we propose a special tooling for disassembling the outer ring of the differential cone bearing in a new energy reducer. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a special tooling for disassembling the outer ring of the differential cone bearing of a new energy reducer.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A special tooling for disassembling the outer ring of the tapered bearing of the differential of a new energy reducer includes a tooling body. The top of the tooling body has a vertical through hole in the middle and a pull rod is inserted through it. The tooling body has a detachable rotating body in the middle. The detachable rotating body is composed of two half-structures. The half-structures are semi-cylindrical. The middle of the two half-structures has a slot. The pull rod can pass through the slot and be threaded to a tapered sleeve. The bottom of the half-structure has a cavity that matches the tapered sleeve. The outer edge of the half-structure away from the cavity has a downwardly sloping edge protrusion.

[0009] The upper surface of the pull rod is threaded, and the pull rod is provided with a propulsion limiting mechanism for restricting and pushing the detachable rotating body to move downward. The top of the tooling body is provided with a drive mechanism for driving the pull rod to rise.

[0010] Preferably, the tooling body is provided with an inverted U-shaped frame, and both ends of the bottom of the inverted U-shaped frame are fixedly connected to an annular block. The through hole for inserting the pull rod is set in the middle of the top of the inverted U-shaped frame. The pull rod is coaxially aligned with the annular block and is detachably rotatably set inside the inverted U-shaped frame.

[0011] Preferably, the lower end of the pull rod is provided with a columnar platform that can abut against the top of the cavity. The radius of the columnar platform is larger than the radius of the pull rod, and the tapered sleeve is threadedly fixed to the bottom of the columnar platform.

[0012] Preferably, the propulsion limiting mechanism includes a locking nut, which is threaded onto the pull rod. The bottom of the locking nut is provided with a locking cover, which has a round hole for the pull rod to pass through. The locking cover is coaxially aligned with the pull rod. The locking nut can move and abut against the top of the locking cover, and the locking cover can abut against the top of the detachable rotating body.

[0013] Preferably, the driving mechanism includes a force-bearing nut, which is threaded onto the pull rod and located at the top of the tooling body, and is rotatably connected to the tooling body.

[0014] Preferably, the top of the pull rod is provided with a pivot, and the top of the pull rod is provided with a transverse insertion hole, through which the pivot can pass and be mounted on the pull rod.

[0015] Preferably, the two halves of the detachable rotating body can be installed in the bearing hole of the product shell, and the bearing outer ring is installed in the bearing hole. The protrusions on the edges of the two halves can abut against the inner diameter edge of the bearing outer ring.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention improves the efficiency of disassembling fixtures for changing bearing outer rings of different outer diameters by setting the detachable rotating body into a two-half structure, effectively simplifying the design process. By setting the tapered sleeve into a tapered structure, the maximum outer diameter of the detachable rotating body is determined according to the thread distance of the downward tightening of the locking nut, adapting to bearing outer rings of different bore diameters and effectively increasing the flexibility of the disassembly fixture. By setting the pull rod into a threaded feature, unnecessary force is effectively saved when manually using the fixture to disassemble the bearing outer ring. By setting a force-bearing nut, when the fixture rotates upward, the force-bearing nut presses down on the fixture body, greatly improving the stability of the disassembly fixture during operation.

[0023] 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.

[0024] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0025] Reference Figure 1 , Figure 2 as well as Figure 3 A special tooling for disassembling the outer ring of a tapered bearing in a new energy reducer includes a tooling body 8. A through hole is vertically provided in the center of the top of the tooling body 8, through which a pull rod 5 passes. A detachable rotating body 4 is provided in the center of the tooling body 8. The detachable rotating body 4 consists of two semi-cylindrical structures 401. The two semi-cylindrical structures 401 have slots 402 in the middle, through which the pull rod 5 passes and is threadedly connected to a tapered sleeve 3. The tapered sleeve 3 is a tapered structure with its tip pointing upwards. After the two semi-cylindrical structures 401 are combined, the pull rod 5 can pass between the two slots 402. The bottom of the semi-cylindrical structures 401 has a cavity 403 that matches the tapered sleeve 3. After the two semi-cylindrical structures 401 are combined, the tapered sleeve 3 moves upwards, allowing the two semi-cylindrical structures 401 to separate by pushing them through the cavity 403. The outer edge of the semi-cylindrical structure 401 facing away from the cavity 403 has a downwardly sloping edge protrusion 404, specifically as shown below. Figure 1 and Figure 3 As shown.

[0026] The two halves 401 of the detachable rotating body 4 can be installed into the bearing bore of the product housing 2, where the outer ring of the bearing is installed. The edge protrusions 404 of the two halves 401 can abut against the inner diameter edge of the outer ring of the bearing 1. The separation and movement of the two halves 401 can adjust the outer diameter of the detachable rotating body 4, thereby accommodating bearing outer rings 1 with different bore diameters, effectively increasing the flexibility of the disassembly fixture.

[0027] As a technical optimization of this utility model, the tooling body 8 is provided with an inverted U-shaped frame. Both ends of the bottom of the inverted U-shaped frame are fixedly connected to an annular block. A through hole for inserting the pull rod 5 is located in the middle of the top of the inverted U-shaped frame. The pull rod 5 is coaxially aligned with the annular block. A detachable rotating body 4 is located inside the inverted U-shaped frame. The inverted U-shaped frame and the annular block effectively ensure the stable placement of the tooling body 8 on the product shell 2, specifically as follows... Figure 2 As shown.

[0028] As a technical optimization of this utility model, the upper surface of the pull rod 5 is threaded, and the lower end of the pull rod 5 is provided with a cylindrical platform that can abut against the top of the cavity 403. The pull rod 5 is threaded above the cylindrical platform. The radius of the cylindrical platform is larger than the radius of the pull rod 5, and the tapered sleeve 3 is threadedly fixed to the bottom of the cylindrical platform.

[0029] As a technical optimization of this utility model, the pull rod 5 is provided with a propulsion limiting mechanism for restricting and pushing the detachable rotating body 4 downward. The propulsion limiting mechanism includes a locking nut 7, which is threaded onto the pull rod 5. The bottom of the locking nut 7 is provided with a locking cover 6, and the bottom edge of the locking cover 6 is provided with an annular stop. The locking cover 6 has a circular hole for the pull rod 5 to pass through. The locking cover 6 is coaxially aligned with the pull rod 5. The locking nut 7 can move and abut against the top of the locking cover 6, and the locking cover 6 can abut against the top of the detachable rotating body 4 to restrict its movement. The locking nut 7 can be turned with a matching wrench. Turning the locking nut 7 can push the locking cover 6 downward.

[0030] The height of the cavity 403 is greater than the height of the columnar platform. When the pull rod 5 is lifted, it can drive the columnar platform to move upward. The columnar platform can abut against the top of the cavity 403 of the two half-structures 401, and thus, in conjunction with the abutting effect of the locking cover 6, the two half-structures 401 can be brought out as a whole.

[0031] As a technical optimization of this utility model, the top of the tooling body 8 is provided with a driving mechanism for driving the pull rod 5 to rise. The driving mechanism includes a force-bearing nut 9, which is threaded onto the pull rod 5. The force-bearing nut 9 is located at the top of the tooling body 8 and is rotatably connected to the tooling body 8. The force-bearing nut 9 can be turned by a matching wrench tool.

[0032] As a technical optimization of this utility model, a rotating shaft 10 is matched to the top of the pull rod 5, and a horizontal insertion hole is provided on the top of the pull rod 5. The rotating shaft 10 can pass through the insertion hole and be mounted on the pull rod 5. The rotating shaft 10 is used to stabilize the pull rod 5.

[0033] In this invention, the working principle of the device is as follows:

[0034] When the equipment is not in operation, the tooling body 8 is manually placed above the bearing hole plane of the product housing 2, ensuring that the two halves 401 of the detachable rotating body 4 are positioned within the bearing holes of the product housing 2. After completing the above operations, the pull rod 5 is fixed by the rotating shaft 10, and then the locking nut 7 is tightened using a wrench, causing it to move downwards along the thread of the pull rod 5. This pushes the locking cover 6, which in turn pushes the detachable rotating body 4 downwards. At this point, the tooling body 8 achieves a stable effect, allowing the two halves 401 of the detachable rotating body 4 to move downwards at any time. The tapered sleeve 3 causes the two halves 401 of the detachable rotating body 4 to move outwards, thus expanding the bottom diameter of the detachable rotating body 4. When the diameter of the rotating body 4 is enlarged to be larger than the inner diameter of the bearing outer ring 1, the edge protrusions 404 of the two half-structures 401 can abut against the inner diameter edge of the bearing outer ring 1, thus locking the bearing outer ring 1, and ensuring that the relative distance between the end faces of the detachable rotating body 4 and the tooling body 8 is slightly greater than the thickness of the bearing outer ring 1; then, first use the rotating shaft 10 to fix the pull rod 5, and then tighten the force nut 9, so that the pull rod 5 moves vertically upward, thereby causing the tapered sleeve 3 to squeeze and drive the detachable rotating body 4 to move upward. Since the detachable rotating body 4 locks the bearing outer ring 1, as it moves upward, the bearing outer ring 1 separates from the product housing 2. After the bearing outer ring 1 is taken away from the bearing hole, the locking nut 7 is loosened upward, and the bearing outer ring 1 can be removed, thus ending the process.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
