Description

Technical Field

[0001] The utility model relates to the technical field of bearing disassembly tools, in particular to a special disassembly instrument for NU bearings. Background Art

[0002] NU bearings are cylindrical roller bearings. During the maintenance of mechanical equipment, it is often necessary to disassemble the bearings for routine inspection or replacement.

[0003] The existing method is to heat the aluminum ring with a flame or a heating furnace, and then use the high-temperature aluminum ring to heat the inner ring of the cylindrical roller to cause it to expand and fall off. During the operation, the aluminum ring heats up slowly and the temperature is difficult to effectively control.

[0004] Therefore, a special disassembly instrument for NU bearings is proposed. Utility Model Content

[0007] A special disassembly instrument for NU bearings includes a heating aluminum ring, which is sleeved on the bearing surface. The surface of the heating aluminum ring is provided with a heating component for heating the heating aluminum ring. A positioning component is provided on the outside of the heating aluminum ring, and a bracket is provided below the positioning component.

[0008] Furthermore, the heating component includes a console, the interface of the console is fixedly connected with electric wires and a temperature sensing integrated wire, the ends of the electric wires and the temperature sensing integrated wire are fixedly connected with terminal posts, the heating aluminum ring has an internal heating wire built in, the end of the internal heating wire is fixedly connected with a power connector, and the power connector is electrically connected to the terminal post.

[0009] Furthermore, the positioning assembly includes a shell, which includes a Y-shaped shell and two arc shells, and the two arc shells are respectively hinged to the two ends of the Y-shaped shell, and the heating aluminum ring is located inside the Y-shaped shell and the two arc shells.

[0010] Furthermore, a first handle is fixedly connected to the surface of the Y-shaped shell, and a second handle and a third handle are fixedly connected to the ends of the two arc shells respectively.

[0011] Furthermore, handle covers are fixedly sleeved on the surfaces of the first handle, the second handle and the third handle, and the handle covers are made of rubber.

[0012] Furthermore, the top surface of the housing is fixedly connected to a line card, and the wires and the temperature sensing integrated line card are connected to the inner wall of the line card.

[0013] The beneficial effects of the utility model are as follows:

[0014] The bearing is clamped into the inner wall of the heated aluminum ring, and the heating temperature is preset by the heating component to heat the heated aluminum ring, thereby heating the bearing. The heating component can monitor the heating temperature and automatically stop heating when the preset temperature is reached. The heating aluminum ring can be limited by the positioning component so that the heating aluminum ring is stably maintained outside the bearing.

[0023] like Figure 1 、 Figure 2 As shown, a special disassembly instrument for NU bearings includes a heated aluminum ring 2, which is mounted on the bearing surface. The surface of the heated aluminum ring 2 is provided with a heating component for heating the heated aluminum ring 2. The exterior of the heated aluminum ring 2 is provided with a positioning component, and a bracket 10 is provided below the positioning component. More specifically, the bearing is inserted into the inner wall of the heated aluminum ring 2. The heating component presets the heating temperature, thereby heating the heated aluminum ring 2. The heating component is capable of monitoring the heating temperature and automatically stops heating when the preset temperature is reached. The positioning component can limit the heated aluminum ring 2 to ensure that the heated aluminum ring 2 is stably maintained outside the bearing. The positioning component is supported by the bracket 10.

[0024] The heating assembly includes a console 1, the interface of which is fixedly connected to an electric wire and a temperature sensing integrated line 9, the ends of which are fixedly connected to a terminal 4. The heated aluminum ring 2 has an internal heating wire 12 built into it, the end of which is fixedly connected to a power connector 13, which is electrically connected to the terminal 4. It should be noted that by achieving circuit connectivity through the console 1, the electric wire and temperature sensing integrated line 9, the terminal 4, and the power connector 13, the internal heating wire 12 is heated, thereby increasing the temperature of the heated aluminum ring 2 and heating the bearing. At the same time, the electric wire and temperature sensing integrated line 9 can provide real-time feedback on the temperature of the heated aluminum ring 2, making it convenient for the user to control the temperature.

[0025] The positioning assembly includes a housing 3, which comprises a Y-shaped shell and two circular shells, each hingedly connected to the ends of the Y-shaped shell. The heating aluminum ring 2 is located within the Y-shaped shell and the two circular shells. More specifically, the Y-shaped shell and the two circular shells can secure and clamp the heating aluminum ring 2, ensuring that the heating aluminum ring 2 fits tightly against the bearing surface, thereby heating the bearing.

[0026] A first handle 5 is fixedly connected to the surface of the Y-shaped housing, and a second handle 7 and a third handle 8 are fixedly connected to the ends of the two arc-shaped housings, respectively. The first handle 5, the second handle 7, and the third handle 8 are all placed on the top of the bracket 10. It should be noted that the provision of the first handle 5, the second handle 7, and the third handle 8 facilitates the handling of the housing 3 and avoids burns caused by direct contact with the housing 3.

[0027] The surfaces of the first handle 5, the second handle 7 and the third handle 8 are all fixedly sleeved with a handle cover 6, and the handle cover 6 is made of rubber. More specifically, by providing the handle cover 6 of rubber material, the user can hold it more stably and the hand is not likely to slip.

[0028] A cable clip 11 is fixedly connected to the top surface of the housing 3, and the wires and the temperature sensing integrated cable 9 are clipped to the inner wall of the cable clip 11. It should be noted that the cable clip 11 can organize and store the wires and the temperature sensing integrated cable 9, preventing them from getting tangled.

[0029] In summary: the bearing is clamped into the inner wall of the heated aluminum ring 2, and the heating temperature is preset by the heating component to heat the heated aluminum ring 2, thereby heating the bearing. The heating component can monitor the heating temperature and automatically stop heating when the preset temperature is reached. The heating aluminum ring 2 can be limited by the positioning component so that the heated aluminum ring 2 is stably maintained outside the bearing. The positioning component can be supported by the bracket 10, which achieves the effect of quickly heating the cylindrical roller of the bearing during use, and can stably control the temperature, making the disassembly of the bearing more convenient.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention.
