Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to an axial positioning device motor. Background Technology

[0002] Traditional axial positioning devices for motors have a series of problems. From the perspective of axial positioning, the positioning accuracy is insufficient. During motor operation, the rotor is prone to axial movement, which not only affects the stability of the motor output, but may also lead to accelerated wear of internal motor components and reduce the service life of the motor. At the same time, due to inaccurate positioning, the motor will generate additional vibration and noise during operation, interfering with the normal operation of the equipment. This effect is more obvious, especially in working scenarios where high precision and quiet environment requirements are required.

[0003] In terms of vibration reduction, existing motor vibration reduction measures are not very effective. The vibration generated by the motor during operation will be transmitted to other parts of the equipment through the motor casing, thereby affecting the stability and reliability of the entire equipment. Long-term vibration may also cause equipment parts to loosen, causing safety hazards. Moreover, existing vibration reduction structures are often quite complex, increasing the manufacturing cost and maintenance difficulty of the motor.

[0004] Publication number: CN217388493U. The installation guide device of this utility model can more easily realize the assembly of motor rotors and stators with larger volume and weight, making the operation simpler and faster for workers, shortening the installation time and thus improving work efficiency.

[0005] To address the aforementioned issues, traditional motors suffer from poor shock absorption, which can affect other components and cause safety hazards. Therefore, we propose an axial positioning device for motors. Utility Model Content

[0015] Compared with the prior art, the present invention provides an axial positioning device motor, which has the following advantages:

[0032] Fixed base 2: Installed on the outside of output end 1, with multiple toothed grooves on the outer surface and a retaining ring 8 inside. The toothed grooves cooperate with the holes on the limiting block 7 to axially position the output end 1 and limit its axial displacement. At the same time, it provides an installation position for the retaining ring 8 and enhances the stability of the overall structure.

[0033] Rotor 3: One of the core components of the motor to achieve energy conversion. It is located inside the motor and has multiple tooth slots on the outside and multiple holes on the surface.

It rotates under the action of electromagnetic induction to realize the conversion of electrical energy and mechanical energy. The design of its tooth slots and holes may be related to the magnetic field distribution, heat dissipation or weight reduction of the motor.

[0034] First heat dissipation ring 4: Installed on the outside of rotor 3 at the end away from limit ring 10, with multiple irregular ventilation holes inside. When the motor is running, it absorbs the heat generated by rotor 3 through heat conduction, and uses the ventilation holes to exchange heat with the outside air to dissipate the heat, reduce the temperature of rotor 3, and ensure the normal operation of the motor.

[0046] Nut 16: Threaded connection at both ends of bolt 15, externally fixed connection to fixing ring 5 and fixing ring 11, which cooperate with bolt 15 to tighten the various parts of the shock absorption assembly, prevent the parts from loosening, and ensure that the shock absorption assembly can work normally during motor operation.

[0047] Instructions for use

[0048] As a key component for motor power output, the output end 1 is fitted with a limiting block 7 and a fixed seat 2, which play a crucial positioning role. Multiple holes on the limiting block 7 engage with the toothed grooves on the outer surface of the fixed seat 2. This special design precisely limits the axial displacement of the output end 1. When the motor is running, if the output end 1 attempts to move axially, the engaging structure between the limiting block 7 and the fixed seat 2 generates a force to prevent displacement, ensuring that the output end 1 remains in its predetermined axial position. The collar 8 is engaged inside the fixed seat 2, further enhancing the overall positioning stability and preventing relative sliding between the fixed seat 2 and the output end 1. This ensures the stability and accuracy of the motor's power output during operation. The vibration damping assembly is a key component for reducing vibration in this motor. The spring 12 within the vibration damping assembly plays a crucial role; it is housed within a hole in the second fixed ring 11. When the motor vibrates during operation, the vibration is first transmitted to the second fixed ring 11, which is connected to the first heat dissipation ring 4. The second fixed ring 11 then transmits the vibration to the spring 12. The spring 12 utilizes its elastic properties to deform and absorb the vibration energy, thereby reducing the transmission of vibration to other parts of the motor. The rubber sleeve 14 also plays an important role in vibration damping; it possesses good flexibility and damping characteristics, enabling... To further buffer vibration, the grooved design at both ends of the rubber sleeve 14 allows it to deform better under vibration, enhancing the shock absorption effect. Furthermore, the flange 13 fixedly connected internally to the rubber sleeve 14 and the fixing plates 6 fixedly connected externally to both ends tightly connect the shock absorption assembly with other components of the motor, ensuring effective transmission of the shock absorption effect and making the motor run more smoothly, reducing the impact of vibration on the overall equipment. The first heat dissipation ring 4 and the second heat dissipation ring 9 are important components for motor heat dissipation; the irregular ventilation openings inside them are key to achieving efficient heat dissipation. The motor generates heat during operation, and this heat is dissipated through heat transfer... The heat is conducted to the first heat dissipation ring 4 and the second heat dissipation ring 9. Due to the presence of the vents, the air can flow freely inside the heat dissipation rings. When the cool air around the motor flows through the vents, it will carry away the heat on the heat dissipation rings, thus dissipating the heat. The irregular vent design increases the contact area between the air and the heat dissipation rings, improving the heat dissipation efficiency. At the same time, the irregular shape of the vents can also disrupt the airflow and form turbulence, further enhancing the heat dissipation effect. This heat dissipation design can dissipate the heat generated by the motor in a timely manner, preventing the motor from degrading or being damaged due to overheating, and ensuring the stability and reliability of the motor during long-term operation.
