Specific implementation method one:

[0030] like Figure 1 and Figure 2 As shown, a bearing heating device includes a main engine base 1, the upper end of the main engine base 1 is rotatably electrically connected to a magnetic induction core 2, a heating object 3 is sleeved on the magnetic induction core 2, the heating object 3 is rotatably fitted between a fixed roller 4 and a driving turntable 5, the fixed roller 4 is fixed to the main engine base 1 through a bracket, and the driving turntable 5 is insulated and fixed to the magnetic induction core 2.

[0031] The working principle and beneficial effects of this embodiment are as follows: the heating object 3 to be heated is placed on the magnetic induction core 2 by adding a sleeve at the lower end of the magnetic induction core 2. The heating object 3 can be a variety of metal parts such as commonly used bearings, gears, bushings, sleeves, diameter rings, pulleys, shrink rings, connectors, etc.

[0032] The magnetic core 2 is wound with a coil rod of an electromagnetic coil, and the host base 1 contains an AC power supply that is energized with the electromagnetic coil in the magnetic core 2. Through the principle of electromagnetic induction, the metal generates eddy currents in the alternating magnetic field to generate heat. When the metal is in the alternating magnetic field, it will generate current due to the electromagnetic induction phenomenon. After the metal generates current, the current will form a spiral flow path inside the metal, so that the heat generated by the flow of current is absorbed by the metal itself, which will cause the metal to heat up quickly.

[0033] During the heating process, the heating object 3 is rotated and fitted between the fixed roller 4 and the driving turntable 5, and then the driving turntable 5 is rotated, which drives the heating object 3 to rotate between the fixed roller 4 and the driving turntable 5, so that the heating object 3 is heated evenly, avoiding the situation of overtemperature and uneven heating during the heating process, thereby reducing the need for manual rotation, avoiding safety hazards and affecting the actual installation effect. Specific implementation method 2:

[0035] like Figure 1 — Figure 5As shown, a bearing heating device is provided, wherein a display 6 is electrically plugged into the front end surface of the main engine base 1, a base 7 is fixed to the upper end of the main engine base 1; a temperature sensor 8 for temperature detection is fixed to the middle end of the base 7, and the temperature sensor 8 is electrically connected to the display 6.

[0036] The working principle and beneficial effects of this embodiment are as follows: a temperature sensor 8 for temperature detection is fixed at the middle end of the base 7, so that the temperature sensor 8 can detect the temperature of the rotating heating object in real time, and the data obtained from the signal is displayed on the display 6, so as to facilitate the determination of the expansion effect, obtain data, and complete the heating. Specific implementation method three:

[0038] like Figure 1 — Figure 5 As shown, a bearing heating device is provided, wherein one end of the base 7 is provided with a slot, one end of the magnetic induction core 2 is fitted and inserted into the slot of the base 7, and the other end of the magnetic induction core 2 is rotatably connected to the base 7 via a rotating shaft.

[0039] The working principle and beneficial effects of this embodiment are as follows: the other end of the magnetic core 2 is rotatably connected to the base 7 via a rotating shaft, which facilitates the removal of one end of the magnetic core 2 from the slot of the base 7, thereby facilitating the installation and disassembly of the heating object 3. At the same time, the magnetic core 2 fits tightly in the slot of the base 7, making it easy for current to pass through for heating. Specific implementation method four:

[0041] like Figure 1 — Figure 5 As shown, a bearing heating device is provided, wherein a side plate 9 is fixed to the side end of the base 7, and a threaded stopper 10 is rotatably inserted on the side plate 9, the threaded stopper 10 being fitted and inserted into the magnetic induction core 2 in the slot of the base 7.

[0042] The working principle and beneficial effects of this embodiment are as follows: the material of the threaded stopper 10 is an insulating material, and the threaded stopper 10 is rotated on the side plate 9, thereby moving the threaded stopper 10 inward or outward, so as to block and disengage the magnetic induction core 2 from being inserted into the slot of the base 7, thereby preventing it from disengaging during the heating process, and facilitating the blocking and control of the displacement of the magnetic induction core 2 in the slot of the base 7. Specific implementation method five:

[0044] like Figure 1 — Figure 5 As shown, a bearing heating device, the fixed roller 4 rotates at the middle end of the bracket, and the bracket is fixed to the rear end of the main machine base 1 by bolts.

[0045] The working principle and beneficial effects of this embodiment are as follows: the fixed roller 4 rotates on the bracket, so as to drive the heating object 3 to rotate between the fixed roller 4 and the driving turntable 5, thereby making the heating object 3 heated evenly. Specific implementation method six:

[0047] like Figure 1 — Figure 5 As shown, a bearing heating device, the driving turntable 5 includes a driving roller connecting bracket 11, a driving roller driver 12 and a driving roller 13, the driving roller connecting bracket 11 is connected to the rotating side of the magnetic induction core 2 by bolts, the driving roller driver 12 is fixed to the driving roller connecting bracket 11 through a motor seat, and the transmission shaft of the driving roller driver 12 rotates the driving roller 13 on the driving roller connecting bracket 11 through a coupling; the material of the driving roller connecting bracket 11 is an insulating material.

[0048] The working principle and beneficial effects of this embodiment are as follows: the driving roller connecting bracket 11 avoids affecting the heating of the actual heated object 3 during the heating process through the characteristics of its insulating material. At the same time, when the magnetic induction core 2 is displaced, the driving roller connecting bracket 11 synchronously drives the driving roller driver 12 and the driving roller 13 to be displaced, thereby avoiding affecting the installation and disassembly of the heated object 3; when heating is required, after the AC power supply is turned on, the driving roller driver 12 on the driving roller connecting bracket 11 drives the driving roller 13 to rotate, and then the driving roller 13 rotates, and the driving roller 13 and the fixed rotating roller 4 clamp the heated object 3, thereby realizing the rotation of the heated object 3 during the heating process, and then the heated object 3 generates current uniformly in the alternating magnetic field, thereby heating itself uniformly, and then making it expand more uniformly due to heat, thereby ensuring the use of on-site interference fit installation. Specific implementation method seven:

[0050] like Figure 1 — Figure 5 As shown, a bearing heating device is provided, wherein one side of the lower end of the driving roller connecting bracket 11 is an arc-shaped end surface, and the other side of the lower end of the driving roller connecting bracket 11 is arc-shaped and inserted into the main machine base 1.

[0051] The working principle and beneficial effects of this embodiment are as follows: one side of the lower end of the driving roller connecting bracket 11 is an arc-shaped end face to avoid affecting the rotation of the driving roller connecting bracket 11 at the joint of the main engine base 1 when it is displaced synchronously with the magnetic induction core 2, thereby avoiding interference; the other side of the lower end of the driving roller connecting bracket 11 is arc-shaped and inserted into the main engine base 1 to ensure its symmetrical support during the displacement process and avoid fixed offset. Specific implementation eight:

[0053] like Figure 1 — Figure 5As shown, a bearing heating device, the end faces of the fixed roller 4 and the driving roller 13 are both concave arc shapes, and the fixed roller 4 and the driving roller 13 are symmetrically arranged; the material of the fixed roller 4 and the driving roller 13 is high temperature resistant acrylic.

[0054] The working principle and beneficial effects of this embodiment are as follows: the end faces of the fixed roller 4 and the driving roller 13 are both in a concave arc shape, and during the rotation process of the clamped heated object 3, the heated object 3 can be clamped according to different widths, which is convenient for driving; the material of the fixed roller 4 and the driving roller 13 are both high-temperature resistant acrylic, not metal material to avoid self-heating, and at the same time, as the temperature of the heated object 3 increases, the fixed roller 4 and the driving roller 13 need to be high-temperature resistant to avoid high-temperature damage.

[0055] The above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention also fall within the protection scope of the present invention.
