[0055] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0056] Example 1
[0057] Please refer to Figure 1 , Figure 2 , Figure 9 This utility model provides a cooling device for the motor of a tire vulcanizing machine, which can cool and dissipate heat from the motor of the tire vulcanizing machine. Figure 9 The image shows a tire vulcanizing machine. The vulcanizing bladder is filled with a high-pressure medium, such as nitrogen. An electric heater heats the medium, and an impeller and other air outlet components are included. The rotation of the impeller agitates the medium inside the bladder, ensuring it fills the vulcanizing bladder evenly and preventing localized overheating or underheating, thus providing uniform heating of the tire. The impeller rotation requires a motor, which can directly drive the impeller or drive it via gears or other transmission methods. Maintaining a tight seal between the high-temperature, high-pressure medium inside the bladder during impeller rotation is difficult, and since the components are typically made of steel, heat is easily conducted towards the motor, causing its temperature to rise.
[0058] To prevent the medium from escaping from the vulcanizing machine, a motor with good sealing performance is generally used. The drive shaft 1 is located outside the transmission housing 5 and is suitable for connecting to the output shaft of the drive component. The driven shaft 3 is located inside the transmission housing 5 and is suitable for driving the rotating component to rotate. A drive shaft magnet seat 11 is provided at the end of the drive shaft 1 facing the driven shaft 3. A driven shaft magnet seat 31 is provided at the end of the driven shaft 3 facing the drive shaft 1. The drive component drives the driven shaft 3 to rotate through a magnetic component. The magnetic component includes a first magnetic body 12 and a second magnetic body 32. The first magnetic body 12 is located at the drive shaft magnet seat 11. The second magnetic body 32 is disposed on the driven shaft magnet seat 31, and the first magnetic body 12 and the second magnetic body 32 are disposed correspondingly. The sealing cover 2 is disposed on the transmission box 5 and protrudes outward toward the transmission box 5. The driven shaft magnet seat 31 extends into the sealing cover 2 and is located between the drive shaft magnet seat 11 and the driven shaft magnet seat 31, separating the drive shaft 1 and the driven shaft 3 and sealing the inner and outer spaces of the transmission box 5. Furthermore, a heat dissipation device 4 is disposed on the sealing cover 2 and / or the drive shaft magnet seat 11 to conduct the temperature of the motor to the ambient air and reduce the temperature of the motor.
[0059] Furthermore, the second magnetic body 32 is made of a high-temperature resistant magnetic material, such as neodymium iron boron, samarium cobalt, or alnico magnets, to meet the requirements of high-temperature operating environments.
[0060] Specifically, in this embodiment, the first magnetic body 12 is disposed on the end face of the active shaft magnet seat 11, and the second magnetic body 32 is disposed on the end face of the driven shaft magnet seat 31, and the two are arranged along the axial direction of the active shaft 1.
[0061] The heat dissipation device 4 can be a pleated structure on the outer peripheral surface of the sealing cover 2, or it can be a heat dissipation fin 41. Several heat dissipation fins 41 are spaced apart on the outer peripheral surface of the sealing cover 2 and are in direct contact with the sealing cover 2. The pleated or finned structure can increase the contact area with the surrounding air, increase the heat dissipation area, and improve the heat dissipation performance.
[0062] Please refer to Figure 2 The heat dissipation fins 41 can be arranged along the axial direction of the driven shaft 3. Please refer to [reference needed]. Figure 3 The heat dissipation fins 41 can also be arranged circumferentially along the sealing cover 2, as long as it facilitates heat transfer. The processing method is simple and easy to control costs.
[0063] The heat dissipation device 4 can use materials with good thermal conductivity, preferably aluminum or silicon carbide, as good thermal conductivity is more conducive to heat conduction.
[0064] Example 2
[0065] Please refer to Figure 4 , Figure 5 , Figure 6Similar to Embodiment 1, the description will not be repeated. In this embodiment, the driving shaft 1 is located outside the driven shaft 3; the first magnetic body 12 is disposed on the outer peripheral surface of the driving shaft magnet seat 11, and the second magnetic body 32 is disposed on the outer peripheral surface of the driven shaft magnet seat 31, and the two are arranged radially opposite to each other; the heat dissipation device 4 can be a pleated structure disposed on the lower end face of the sealing cover 2, or it can be a heat dissipation fin 41, and a plurality of heat dissipation fins 41 are spaced apart on the lower end face of the sealing cover 2.
[0066] Please refer to Figure 5 The heat dissipation fins 41 can be arranged radially along the driven shaft 3, please refer to... Figure 6 The heat dissipation fins 41 can also be arranged concentrically with the driven shaft 3 along the circumference of the sealing cover 2.
[0067] Example 3

The heat dissipation device 4 can be a heat dissipation hole 42, which penetrates the drive shaft magnet seat 11 and connects the sealing cover 2 with the external environment. The heat of the sealing cover 2 is conducted into the receiving recess 13, and its heat can be further conducted into the environment below the drive shaft magnet seat 11 through the heat dissipation hole 42.
[0069] like Figure 8 As shown, the four heat dissipation holes 42 are arranged in an array with the axis of the drive shaft 1 as the center. The processing method is simple and does not affect the rigidity of the drive shaft magnet seat 11.
