[0025] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. In this specification, "in one embodiment" does not mean the same embodiment, nor is it an independent or alternative embodiment.

[0026] Embodiment

[0027] Reference Figures 1-5 For the embodiments of the present application, the embodiments provide a double-row tapered roller bearing which is convenient to disassemble, comprising,

[0028] The bearing mechanism 100 comprises two inner rings 101, a plurality of rollers 102 arranged on the surface of the inner ring 101, and an outer ring 103 sleeved on the outer side of the inner ring 101.

[0029] The dismounting mechanism 200 comprises a heating component 201 for uniformly heating the inner ring 101, and an electrified component 202 for conveniently electrifying and heating the pipe body 201a.

[0030] Wherein, through the cooperation between the heating component 201 and the electrified component 202, the inner ring 101 can be uniformly heated to cause thermal expansion, thereby reducing the interference between the inner ring 101 and the shaft, reducing the friction, facilitating the dismounting of the bearing, solving the problem that the traditional bearing is difficult to dismount when cooperating with the shaft too tightly, improving the efficiency of dismounting the bearing, and providing convenience for the maintenance and replacement of the bearing.

[0031] Specifically, the heating component 201 comprises a pipe body 201a for heating the inner ring 101, and a mounting hole 201b arranged inside the inner ring 101 and cooperating with the pipe body 201a.

[0032] Further, the pipe body 201a is arranged in a spiral shape, and the pipe body 201a is located inside the mounting hole 201b.

[0033] The surface of the pipe body 201a is attached to the hole wall of the mounting hole 201b, the pipe body 201a is arranged in a spiral shape, the contact area between the pipe body 201a and the inner ring 101 is increased, and the heating effect on the inner ring 101 is improved. The mounting hole 201b installs and accommodates the pipe body 201a, and improves the use stability of the pipe body 201a.

[0034] Preferably, the heating component 201 further comprises two sealing plugs 201c for sealing the end of the pipe body 201a, and the two sealing plugs 201c are respectively clamped on the end of the pipe body 201a.

[0035] The sealing plug 201c is used to block and seal the end of the pipe body 201a, so as to prevent dust from entering the inside of the pipe body 201a and affecting the heating effect of the pipe body 201a.

[0036] Further, the pipe body 201a is made of nickel-chromium alloy, and the sealing plug 201c is made of rubber.

[0037] The nickel-chromium alloy has high heating efficiency, can quickly generate a large amount of heat after being electrified due to its high resistivity, and has good high-temperature resistance and is not easy to oxidize or deform at high temperature. The sealing plug 201c made of rubber can better seal the end of the pipe body 201a and prevent dust from entering the inside of the pipe body 201a.

[0038] Specifically, the electrified component 202 comprises a connecting frame 202a fixedly installed in the inside of the pipe body 201a, a cylinder 202b fixedly installed on the surface of the connecting frame 202a, and a connecting column 202c elastically installed in the inside of the cylinder 202b.

[0039] The end of the connecting column 202c extends to the outside of the cylinder 202b, and the connecting frame 202a, the spring 202d and the connecting column 202c are all conductive metals.

[0040] Further, the electrified component 202 further comprises a spring 202d fixedly installed on the surface of the connecting frame 202a, and the connecting column 202c is fixedly connected with the end surface of the spring 202d.

[0041] The spring 202d is used to elastically apply to the connecting column 202c, so that when the sealing plug 201c is opened, the connecting column 202c can be automatically popped out, and the wire can be connected with the connecting column 202c.

[0042] In use, when the bearing is disassembled, the two sealing plugs 201c at the end of the pipe body 201a are removed, so that the two ends of the pipe body 201a are open. When the sealing plug 201c is removed, the connecting column 202c is popped out under the elastic force of the spring 202d, and there are two ways to uniformly heat the inner ring 101.

[0043] First, connect the conduit to one end of the pipe body 201a, and heat the oil through the pipe into the inside of the pipe body 201a, and discharge from the other end of the heating component 201, and heat the oil when it passes through the inside of the pipe body 201a, and the pipe body 201a is designed in a spiral, so that the inner ring 101 is uniformly heated, and the material of the inner ring 101 expands after being heated, causing the inner diameter of the inner ring 101 to increase slightly, and because the inner ring 101 is interference fit with the shaft, the interference between the inner ring and the shaft decreases after the inner diameter increases, thereby reducing the contact pressure between the two, so as to achieve the purpose of facilitating the disassembly of the bearing;

[0044] Second, connect the wire to the two connecting columns 202c to form a circuit, and power the circuit, and the pipe body 201a will generate heat when powered, which will uniformly heat the inner ring 101.

[0045] In summary, through the cooperation between the heating component 201 and the powered component 202, the inner ring 101 can be uniformly heated to cause thermal expansion, thereby reducing the interference between the inner ring 101 and the shaft, reducing the friction, facilitating the disassembly of the bearing, solving the problem that the traditional bearing is difficult to disassemble when it is too tightly fitted with the shaft, improving the efficiency of bearing disassembly, and providing convenience for bearing maintenance and replacement.
