[0002] At present, bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Bearings will be worn and damaged during long-term use, and equipment maintenance personnel are required to dismantle the bearings in time for replacement. Ceramic bearings are widely used in precision machinery, aerospace, medical equipment and other fields due to their good wear resistance, high temperature resistance, and superior high-speed performance. When disassembling ceramic bearings, due to the high hardness and fragility of the material, specially designed tools are usually required to avoid damaging the bearings.

DETAILED DESCRIPTION

[0019] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0020] like Figure 1-5 As shown, a ceramic bearing removal tool comprises: a frame 1 and a pull rod 5, the frame 1 is provided with multiple groups of connecting grooves 2, the frame 1 is meshingly installed with threaded rods 3, the inside of the connecting grooves 2 is movably provided with a first connecting piece 4, and the top of the pull rod 5 is fixedly provided with a second connecting piece 10. The ceramic bearing removal tool is mainly composed of the frame 1, the pull rod 5 and the threaded rod 3. Through the installation of the first connecting piece 4 and the second connecting piece 10, the multiple groups of pull rods 5 can be more conveniently installed on the frame 1 through the connecting grooves 2, thereby improving the assembly efficiency of the ceramic bearing removal tool, enabling the staff to more quickly remove the ceramic bearings, and improving the working efficiency and practicality of the removal tool.

[0021] like Figure 1As shown, a limit piece 6 is installed at the bottom of the pull rod 5. When in use, the bottom end of the pull rod 5 can be inserted into the middle of the inner ring and the outer ring of the ceramic bearing through the limit piece 6 installed at the bottom. When the bottom end of the pull rod 5 is inserted into the inside of the ceramic bearing and the top end is connected to the frame 1 through the first connecting piece 4 and the second connecting piece 10, the staff only needs to rotate the threaded rod 3 to move the threaded rod 3. Because the bottom end of the threaded rod 3 is in contact with an external object, as the threaded rod 3 moves, the multiple groups of pull rods 5 on the frame 1 will move upward, generating a pulling force, thereby smoothly removing the bearing from the journal.

[0022] like Figure 3 As shown, the outside of the first connecting member 4 is provided with a threaded outer groove 7, and a limiting ring 8 is provided on the first connecting member 4. A threaded inner groove 9 is provided on the limiting ring 8, and the threaded inner groove 9 can mesh with the threaded outer groove 7. The first connecting member 4 is movably installed in the connecting groove 2 of the frame 1 through the limiting ring 8, and the limiting ring 8 is installed on the first connecting member 4 through the meshing of the threaded inner groove 9 and the threaded outer groove 7. After the limiting ring 8 is disassembled, the first connecting member 4 can be taken out from the connecting groove 2, so that the first connecting member 4 can be disassembled and assembled while being not easily lost during use.

[0023] like Figure 4 and Figure 5 As shown, the first connecting member 4 is provided with an installation groove 12, and two groups of blocks 13 are fixedly provided inside the installation groove 12. A limiting groove 11 is provided inside the second connecting member 10. When the pull rod 5 is installed, the second connecting member 10 fixedly installed on the pull rod 5 will enter the first connecting member 4 through the installation groove 12. When the second connecting member 10 enters the installation groove 12, as the staff rotates the first connecting member 4, the two groups of blocks 13 fixedly installed in the installation groove 12 will be inserted into the upper limit groove 11 of the second connecting member 10, so that the pull rod 5 can be fixed to the first connecting member 4 through the second connecting member 10, so that the pull rod 5 can be more conveniently installed on the frame 1 through the connecting groove 2, thereby improving the assembly efficiency of the ceramic bearing disassembly tool, enabling the staff to disassemble the ceramic bearing more quickly, and improving the working efficiency and practicality of the disassembly tool.

[0024] Working principle: The ceramic bearing removal tool is mainly composed of a frame 1, a pull rod 5 and a threaded rod 3.

When in use, the bottom end of the pull rod 5 can be inserted into the middle of the inner ring and the outer ring of the ceramic bearing through the limit piece 6 installed by the bottom engagement. When the bottom end of the pull rod 5 is inserted into the inside of the ceramic bearing and its top end is connected to the frame 1 through the first connecting piece 4 and the second connecting piece 10, the staff only needs to rotate the threaded rod 3 to move the threaded rod 3. Because the bottom end of the threaded rod 3 is in contact with an external object, as the threaded rod 3 moves, the multiple groups of pull rods 5 on the frame 1 will move upward, causing it to generate tension, thereby smoothly removing the bearing from the journal. The first connecting piece 4 is movably installed on the frame through the limit ring 8. 1, the limiting ring 8 is installed on the first connecting member 4 through the meshing of the inner thread groove 9 and the outer thread groove 7. After the limiting ring 8 is disassembled, the first connecting member 4 can be taken out from the connecting groove 2, so that the first connecting member 4 can be disassembled and assembled, and it is not easy to lose when in use. When the pull rod 5 is installed, the second connecting member 10 fixedly installed on the pull rod 5 will enter the interior of the first connecting member 4 through the installation groove 12. After the second connecting member 10 enters the installation groove 12, as the staff rotates the first connecting member 4, the two groups of card blocks 13 fixedly installed in the installation groove 12 will be inserted into the interior of the upper limit card groove 11 of the second connecting member 10, so that the pull rod 5 can be fixed to the first connecting member 4 through the second connecting member 10, so that the pull rod 5 can be more conveniently installed on the frame 1 through the connecting groove 2, thereby improving the assembly efficiency of the ceramic bearing removal tool, enabling the staff to more quickly remove the ceramic bearing, and improving the working efficiency and practicality of the removal tool.
