Description

Technical Field

[0001] The utility model relates to the field of bearing disassembly, in particular to a hydraulic bearing disassembly device. Background Art

[0002] In the field of mechanical manufacturing and maintenance, the disassembly of bearings and shafts is a common and important task. Bearing disassembly often relies on manual labor or the use of special pulling tools and other methods.

[0003] However, manual labor is not efficient in disassembling large bearings, and is time-consuming and labor-intensive. Utility Model Content

[0004] In order to overcome the above-mentioned deficiencies, the present invention provides a hydraulic bearing disassembly device.

[0005] The technical solution adopted by this utility model:

[0006] A hydraulic bearing disassembly device includes a top plate, the four corners of the bottom of the top plate are fixedly connected to support legs, a support platform is fixedly connected between the middle parts of the four support legs, a fixing hole is opened in the center of the top of the support platform, the middle part of the top plate is fixedly embedded in the hydraulic cylinder, the top plate is fixedly connected to the outer wall of the cylinder barrel of the hydraulic cylinder, and the bottom end of the hydraulic rod of the hydraulic cylinder is located directly above the center of the fixing hole.

[0007] Beneficial effects of the utility model:

[0008] The utility model utilizes the powerful thrust generated by the hydraulic cylinder to quickly and efficiently separate the bearing from the shaft, greatly improving the disassembly efficiency. The entire disassembly process is highly automated and can be completed by simply operating the switch of the hydraulic cylinder, reducing the complexity and labor intensity of manual operation.

[0013] like Figure 1-3As shown: A hydraulic bearing disassembly device includes a top plate 1, the four corners of the bottom of the top plate 1 are fixedly connected to support legs 2, a support platform 3 is fixedly connected between the middle parts of the four support legs 2, a fixing hole 4 is opened in the center of the top of the support platform 3, a hydraulic cylinder 5 is fixedly embedded in the middle of the top plate 1, the top plate 1 is fixedly connected to the outer wall of the cylinder barrel of the hydraulic cylinder 5, and the bottom end of the hydraulic rod of the hydraulic cylinder 5 is located directly above the center of the fixing hole 4.

[0014] First, insert the shaft 6 to be disassembled into the fixing hole 4 at the top of the support platform 3 to ensure that the shaft 6 is stable and placed vertically. At this time, the bearing 7 sleeved on the top of the outer wall of the shaft 6 will be clamped on the upper surface of the support platform 3.

[0015] After confirming that the shaft 6 and the fixing hole 4 are correctly aligned, the bottom of the bearing 7 is firmly supported to prevent displacement or shaking during the disassembly process. Then, the hydraulic cylinder 5 fixedly installed in the middle of the top plate 1 is started. The hydraulic cylinder 5 starts to work, and its output shaft (hydraulic rod) gradually extends downward until the bottom end of the output shaft contacts the top end of the shaft 6 and applies pressure.

[0016] As the output shaft of the hydraulic cylinder 5 continues to press downward, a thrust is generated on the shaft 6. Due to a certain interference fit or friction between the bearing 7 and the shaft 6, this thrust needs to gradually overcome these resistances. When the thrust is large enough, the shaft 6 will begin to be gradually pressed out of the inner ring of the bearing 7 until it is completely separated.

[0017] When the shaft 6 is completely separated from the bearing 7, the hydraulic cylinder 5 stops working and the output shaft retracts. At this time, the shaft 6 and the bearing 7 can be easily removed to complete the disassembly process.
