Description

Technical Field

[0001] This utility model relates to the field of bearing installation technology for mechanical equipment, specifically to a bearing installation structure for mechanical equipment and a matching bearing disassembly fixture. Background Technology

[0002] Bearings are commonly used rotating components in mechanical equipment. Their main function is to support rotating mechanical bodies and reduce the coefficient of friction during movement. Bearings are used very frequently and require regular maintenance and replacement to ensure the stable operation of the mechanical equipment. Large mechanical equipment typically has bearing housings to accommodate larger bearings and support heavier loads. Figure 1 As shown, compared with small bearings installed in ordinary bearing housings, large bearings installed in bearing housings are difficult to disassemble due to the confinement of the bearing housing at one end and the bearing being close to the bottom of the bearing housing. This makes maintenance and replacement time-consuming and affects production progress. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a bearing installation structure for mechanical equipment and a matching bearing disassembly fixture, which can solve the problem that the bearing cannot be quickly removed due to the special structure of the bearing chamber.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] In a first aspect, this utility model provides a bearing mounting structure for mechanical equipment, used for mounting bearings, comprising:

[0006] The bearing housing has an open end and a closed end at the other end.

[0028] This utility model provides a bearing mounting structure for mechanical equipment and a matching bearing disassembly fixture. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following provides a more detailed description. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit its scope.

[0029] In the description of this utility model, it should be understood that the terms "upper", "lower", "inner", "outer", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] The present invention will now be described in detail with reference to the accompanying drawings:

[0031] Reference Figure 2This embodiment provides a bearing mounting structure for mechanical equipment, including: a bearing chamber 1, a disassembly ring 2, and a bearing end cover 3. The bearing chamber 1 has an open end and a closed end; the disassembly ring 2 is disposed inside the bearing chamber 1, with one end face of the disassembly ring 2 contacting the closed end of the bearing chamber 1, i.e., the disassembly ring 2 is installed at the inner bottom of the bearing chamber 1; the bearing end cover 3 is fixed to the open end of the bearing chamber 1 by bolts.

[0032] Reference Figure 3 The above-mentioned bearing mounting structure is used to install bearings. During installation, the disassembly ring 2 is first installed in the bearing chamber 1, and then the bearing 4 equipped with the mandrel 5 is installed. After the disassembly ring 2, bearing 4 and mandrel 5 are installed, the bearing end cover 3 is fixed to the open end of the bearing chamber 1 with bolts.

[0033] In this embodiment, refer to Figure 5 To facilitate the disassembly of bearing 4 without affecting its installation, the inner ring of the disassembly ring 2 is provided with an internal thread, and the outer diameter of the disassembly ring 2 is equal to the outer diameter of bearing 4, the inner diameter of the disassembly ring 2 is smaller than the inner diameter of bearing 4, and the disassembly ring 2 meets the machining accuracy required by bearing 4.

[0034] In this embodiment, refer to Figure 4 To facilitate faster disassembly of bearing 4, the contact area between the outer ring of disassembly ring 2 and bearing chamber 1 can be reduced. Specifically, a bearing chamber flare 101 is provided at one end of bearing chamber 1 near its closed end, and the height of bearing chamber flare 101 is lower than the height of disassembly ring 2.

[0035] In this embodiment, refer to Figure 5 To facilitate the disassembly of bearing 4, the disassembly ring 2 can be completely fitted onto the disassembly rod of the disassembly fixture described below, so that the bottom surface of the disassembly ring 2 can be more easily separated from the bearing chamber 1. A first stepped surface 201 is provided on the outer edge of the disassembly ring 2 near the closed end of the bearing chamber 1.

[0036] In this embodiment, refer to Figure 5 To prevent the disassembly ring 2 from rubbing against the end of the mandrel 5, a second stepped surface 202 is provided on the outer edge of the disassembly ring 2 on the side away from the closed end of the bearing chamber 1. The second stepped surface 202 provides a certain gap between the end of the mandrel 5 and the disassembly ring 2, preventing them from contacting each other.

[0037] In this embodiment, refer to Figure 2 In order to securely install the bearing 4, an end cap ring 301 is provided on one end face of the bearing end cap 3 near the bearing chamber 1, and the outer diameter of the end cap ring 301 matches the inner diameter of the bearing chamber 1; and in order to prevent the setting of the disassembly ring from affecting the bearing installation, the depth of the bearing chamber 1 is increased, and the depth of the bearing chamber 1 is equal to the sum of the height of the disassembly ring 2, the height of the bearing 4, and the height of the end cap ring 301.

[0038] Reference Figure 6 This embodiment also provides a bearing disassembly fixture that is compatible with the above-mentioned bearing mounting structure. The bearing disassembly fixture includes a disassembly rod 6. One end of the disassembly rod 6 is provided with an external thread that matches the internal thread of the disassembly ring 2, and the height of the external thread is not less than the depth of the bearing chamber 1. The other end of the disassembly rod 6 is provided with an external hexagonal boss 601.

[0039] The aforementioned external hexagonal boss 601 is of standard size and can be adapted to the internal hexagonal socket. During disassembly, an internal hexagonal socket wrench can be fitted onto the end of the disassembly rod 6 where the external hexagonal boss 601 is located, and the disassembly rod 6 can be rotated by the wrench.

[0040] In addition, a steel ball 602 is embedded in the center of the end face of the disassembly rod 6 away from the external hexagonal boss 601, which can reduce the frictional resistance when the disassembly rod 6 rotates.

[0041] Both the disassembly ring 2 and the disassembly rod 6 mentioned above undergo heat treatment to ensure hardness and strength.

[0042] Reference Figure 7 The process of disassembling the bearing installed in the bearing mounting structure of this embodiment using the matching bearing disassembly tool is as follows:

[0043] First, remove the bearing end cover and take out the mandrel that mates with the inner ring of the bearing. Insert the threaded end of the disassembly rod into the bearing and rotate the disassembly rod so that the threaded end of the disassembly rod is screwed into the disassembly ring. Continue to turn the disassembly rod. When the steel ball on the end face of the disassembly rod contacts the bottom surface of the bearing housing, use the reaction force of the thread to push the disassembly ring and the bearing outward together until the outer ring of the bearing is disengaged from the bearing housing, thus completing the disassembly. This allows the bearing to be removed quickly without damaging it.

[0044] It should be noted that any parts not mentioned in this utility model can be achieved by adopting or referencing existing technologies.

[0045] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
