Description

Technical Field

[0001] The invention belongs to the technical field of motors, and in particular relates to a detachable bladeless fan cooler for a motor. Background Art

[0002] Servo motor refers to the engine that controls the operation of mechanical elements in the servo system. It is an auxiliary motor indirect speed change device. The servo motor can control the speed and position accuracy very accurately. It can convert the voltage signal into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator and has the characteristics of small electromechanical time constant and high linearity. It can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. It is divided into two categories: DC motor and AC servo motor. Its main characteristics are that there is no self-rotation when the signal voltage is zero, and the speed decreases at a uniform speed as the torque increases. As one of the important components of the electrical servo system, the servo motor has been widely used in the industrial field with its advantages of small size, large torque and high efficiency. The loss generated during the operation of the servo motor will cause the temperature of the motor to rise. If the operating temperature exceeds the maximum temperature allowed by the insulation material, the aging process of the insulation layer will be accelerated, shortening the life of the motor, or even damaging the motor; if the operating temperature of the permanent magnet exceeds its maximum allowable temperature, it may cause the permanent magnet to demagnetize and affect the performance of the motor. Therefore, the motor must be cooled so that the temperature rise of its various structures can be kept within the allowable range to ensure the safe and normal operation of the motor.

[0003] However, the existing servo motor air cooling device is not easy to install and disassemble, and it is not convenient for people to quickly and effectively install the servo motor with the air cooling device, which increases the time required for installation, increases people's work pressure, and does not meet people's work needs; when the servo motor needs to be inspected, the servo motor air cooling device that is not easy to disassemble further reduces the work efficiency during the inspection, bringing inconvenience to people's work.

[0004] The bladeless fan uses technology from jet engines and automobile turbochargers to draw in air through the air intake holes at the bottom. An impeller hidden inside the edge of the ring ejects the air in a circular trajectory, ultimately forming an uninterrupted stream of cold air. Summary of the invention

[0005] In order to solve the above technical problems, the present invention proposes a detachable bladeless fan cooler for a motor. The loss generated when the servo motor is running will cause the temperature of the motor to rise. If the operating temperature exceeds the maximum temperature allowed by the insulating material, the aging process of the insulation layer will be accelerated, shortening the life of the motor, or even damaging the motor; if the operating temperature of the permanent magnet exceeds its maximum allowable temperature, it may cause the permanent magnet to demagnetize and affect the performance of the motor. Therefore, the motor must be cooled so that the temperature rise of its various structures can be kept within the allowable range to ensure the safe and normal operation of the motor. The present invention can use a bladeless fan to cool the servo motor, align the air outlet of the bladeless fan with the gap between the servo motor housing and the windshield, improve the heat dissipation efficiency, and change its appearance structure so that the detachable servo motor bladeless fan cooler is easy to install and disassemble.

[0006] To achieve the above object, the technical solution adopted by the present invention is: A detachable bladeless fan cooler for a motor comprises a windshield, an annular nozzle and a base with a centrifugal compressor, wherein the windshield is mounted at the rear end of a servo motor to be cooled, the servo motor to be cooled is supported by a motor support seat below, a combined structure with the servo motor to be cooled is arranged in the windshield and is combined with a mortise and tenon structure, the windshield is mounted on the front side of the annular nozzle, an annular nozzle is arranged on the rear side of the windshield, and the annular nozzle is connected to the base with the centrifugal compressor through a hollow threaded connection structure.

[0007] As a further improvement of the present invention, the hollow threaded connection structure includes a hollow outer spiral connection column and an inner spiral connection column, and the hollow outer spiral connection column at the upper end of the base with the centrifugal compressor is spirally combined with the inner spiral connection column at the lower end of the annular nozzle.

[0008] As a further improvement of the present invention, in the step, there are two internal threaded columns on the upper rear plane of the wind shield and the supporting structure that contacts the servo motor to be cooled. When the wind shield and the servo motor to be cooled are combined, the internal threaded columns are aligned with the internal threaded columns on the servo motor housing and are fixed by bolts. The bolts can better fix the wind shield.

[0009] As a further improvement of the present invention, the four corners of the windshield plate are provided with heat dissipation structures, so as to achieve the purpose of enhancing heat dissipation by increasing the contact area.

[0010] As a further improvement of the present invention, one side of the motor support seat has a long strip with a circular arc depression that conforms to the outer contour of the servo motor to be cooled, and the other side has two square blocks that match the servo motor to be cooled, so that this support seat can fix the servo motor.

[0011] The beneficial effects of the present invention are: The bladeless fan is used in the forced air cooling of the servo motor, and its air outlet is aimed at the gap between the servo motor housing and the wind shield to improve the heat dissipation efficiency. The blades are inside the base, which is safer than the previous air cooling device with the fan at the rear of the servo motor.

[0012] The windshield and the nozzle are combined into one body, connected with the base with the centrifugal compressor through threads, supporting one side, and the other side is fixed with a support base to support the servo motor, so that the modified detachable servo motor bladeless fan cooler can be easily transported, installed and disassembled.

[0013] A fixing hole is provided at a position of the servo motor housing corresponding to the rear end of the wind shield. The wind shield is movably connected to the housing through fixing bolts. The fixing bolts are used to facilitate installation and fixing of the wind shield. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1-9 As shown, the lower end of the annular nozzle 4 has a hollow external spiral connecting column 6-1 engraved with an external spiral, which can be connected with Figure 5 The inner spiral connecting column 5-2 with an inner spiral is engraved on the upper end of the base 5 with the centrifugal compressor. Figure 7 The integral part of the windshield 3 and the annular nozzle 4 shown in the figure is combined with the servo motor. The supporting structure 3-3 of the windshield 3 can support the servo motor 1 to be cooled, and increase its air cooling area, while increasing its heat dissipation area, so as to better dissipate heat and cool the servo motor 1 to be cooled. The combined structure 3-2 of the windshield 3 can firmly combine the windshield 3 and the servo motor 1 to be cooled together. The heat dissipation structure 3-1 of the windshield 3 achieves the purpose of enhancing heat dissipation by increasing the contact area. There are two internal threaded columns on the supporting structure 3-3 where the upper rear plane of the windshield 3 and the servo motor 1 to be cooled are in contact. When the windshield 3 and the servo motor 1 to be cooled are combined, they are aligned with the internal threaded columns on the housing of the servo motor, and the windshield 3 is better fixed by bolts 7. Then, Figure 5 The hollow outer spiral connecting column 6-1 at the upper end of the base 5 with the centrifugal compressor is spirally connected with the inner spiral connecting column 5-2 at the lower end of the annular nozzle 4, and finally Figure 6 As shown, the rear end of the servo motor 1 to be cooled is mounted on a motor support seat 2.
