Description

Technical Field

[0001] This utility model relates to the field of vibration motor technology, specifically to an air-cooled vibration motor. Background Technology

[0002] Vibratory motors are widely used in industrial production, especially in equipment that requires continuous or periodic vibration, such as vibrating screens, vibrating feeders, and vibration test benches. With continuous technological advancements, the application range of vibratory motors is gradually expanding, particularly in high-efficiency, stable, and reliable operating environments, which place higher demands on the heat dissipation and vibration control of vibratory motors.

[0003] Traditional vibratory motors mostly rely on built-in fans or external air-cooling systems to ensure stable motor temperatures. However, because vibratory motors generate significant vibrations during operation, these traditional cooling systems are easily affected over long-term use, leading to reduced heat dissipation efficiency and consequently impacting the motor's operational stability and lifespan. Furthermore, the vibrations generated by vibratory motors not only affect equipment performance but may also cause noise pollution to the surrounding environment.

[0004] To address the aforementioned issues, most existing air-cooled vibratory motors suffer from the following drawbacks:

[0005] Insufficient heat dissipation: The airflow guidance effect in the existing air-cooling system is poor, resulting in uneven heat dissipation. The temperature in some areas rises too quickly, and the motor may fail due to overheating.

[0006] Poor vibration control: Traditional designs have relatively simple control over motor vibration, which cannot effectively eliminate the unbalanced load of the motor during high-speed operation. This can easily cause unstable operation of the vibrating motor and even affect the overall reliability of the equipment.

[0007] Complex structure and excessive weight: Some traditional vibration motors have overly complex structures, resulting in excessive weight of the equipment, which increases the difficulty of installation and maintenance, and consumes more energy.

[0008] Therefore, in order to improve the performance and working stability of vibration motors, there is an urgent need for an air-cooled vibration motor that can effectively solve problems such as uneven heat dissipation, poor vibration control, and complex structure. Utility Model Content

[0009] This utility model relates to an air-cooled vibration motor, aiming to improve the heat dissipation efficiency and optimize its operational stability through improved structural design. Specifically, this utility model includes the following key components and their functional layout:

[0010] Motor housing: The core component of this invention is the motor housing, which houses the drive motor. The motor housing is made of robust metal, effectively supporting the drive motor and other components, and withstanding external vibration loads. Protective wind shields are installed on both sides of the motor housing to protect the motor from external environmental influences.

[0011] Drive motor: The drive motor is installed inside the motor housing. Its function is to provide a power source and drive the entire system through connection with the rotary disc assembly. The surface of the drive motor has several finned channels. These finned channels can effectively promote airflow, enhance heat dissipation, and ensure that the motor will not be damaged by overheating when operating at high speed.

[0012] Rotary disk assembly: The rotary disk assembly is an important component of this utility model. By being fixed to the output shaft surfaces on both sides of the drive motor, the rotary disk assembly can achieve stable rotational motion and generate the required wind power. Inside the rotary disk assembly, turbine blades and intake fan blades are provided to guide and accelerate airflow, thereby enabling effective heat dissipation for the motor.

[0013] Bearing rings and moving rings: The two sides of the motor housing are fixedly connected by bearing rings to ensure the stability of the motor. In the rotor assembly, the moving ring and bearing ring are smoothly connected by ball bearings to achieve rotation. This design effectively reduces rotational friction and improves the operating efficiency of the motor.

[0014] Offset weight: The offset weight is mounted on the surface of the rotary disk assembly and is made of high-density metal alloy. Its center of gravity is offset from the center of the rotary disk assembly. This design effectively compensates for vibrations that may occur during system rotation, enhancing the stability and shock resistance of the vibratory motor.

[0015] This invention optimizes the heat dissipation structure of the motor through the rational configuration of its components, thereby improving its working efficiency and stability. In particular, the rational layout of the finned flow channels, turbine blades, and intake fan blades effectively ensures efficient airflow and heat dissipation, providing a solid technical foundation for the widespread application of air-cooled vibratory motors.

[0016] The beneficial effects achieved by this utility model are as follows:

[0017] 1. In this utility model, the design of incorporating finned flow channels and a protective shroud within the motor housing effectively promotes airflow, improves the motor's heat dissipation efficiency, and prevents damage from overheating. Especially in high-frequency vibration environments, the heat dissipation effect significantly enhances the motor's operational stability.

[0018] 2. In this invention, the ball bearing design between the bearing ring and the moving ring reduces friction and wear between components, improves the motor's working efficiency, and extends its service life. Furthermore, the configuration of the turbine blades and intake fan blades in the rotor assembly effectively promotes airflow, reduces temperature rise, and further improves the motor's durability.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0027] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0028] The following is in conjunction with the appendix Figures 1-5 This invention describes an air-cooled vibration motor provided by some embodiments of the present invention.

[0029] This embodiment employs the following configuration: the motor housing 100 is an integral metal casting, cylindrical in shape, with a high-temperature resistant and corrosion-resistant coating on its outer surface. A drive motor 120 is mounted inside, and connected to protective shrouds 110 on both sides of the motor housing 100 via finned flow channels 121. The protective shrouds 110 have multiple air vents and grilles on their surface to enhance airflow and ensure good heat dissipation during motor operation.

[0030] The drive motor 120 is a common type of electric motor, capable of providing the necessary power output. Several finned flow channels 121 are fixed inside the motor, and these finned flow channels 121 communicate with the inner cavity of the motor housing 100. The drive motor 120 drives the rotary disk assembly 200 to operate by rotating.

[0031] The rotary disk assembly 200 includes multiple turbine blades 220 and intake fan blades 230, which are fixedly connected to the motor housing 100 and the drive motor 120 via a bearing ring 130. The rotation of the rotary disk assembly 200 promotes airflow, thereby improving the air-cooling effect and preventing the motor from overheating. The turbine blades 220 are arranged in a spiral shape, which can guide airflow into the interior of the rotary disk assembly 200 during rotation and guide the airflow through the heat dissipation path.

[0032] The bearing ring 130 and the moving bearing ring 210 are respectively installed on both sides of the motor housing 100. The bearing ring 130 achieves rotational contact with the moving bearing ring 210 through the ball bearings 211, ensuring the smooth rotation of the rotary disc assembly 200. The ball bearings 211 can effectively reduce friction, reduce wear, and improve the service life of the motor.

[0033] The offset block 300 is fixed to the surface of the rotary disk assembly 200 and is made of high-density metal alloy. Its center of gravity is offset from the center of the rotary disk assembly 200, which plays a role in balancing rotational vibration. The offset block 300 ensures the stability of the motor during operation and reduces vibration and noise caused by unbalanced load.

[0034] In this embodiment, to further improve heat dissipation, the turbine blades 220 are arranged in a spiral shape and work together with the intake fan blades 230 to form a highly efficient airflow guiding system. During the rotation of the rotor assembly 200, the airflow is first guided into the rotor assembly by the turbine blades 220, and then further accelerated by the intake fan blades 230, enhancing the airflow circulation. When the airflow passes through the inner cavity of the motor housing 100, the finned flow channels 121 effectively guide the airflow to exchange heat with the heat generated inside the motor, carrying away heat and ensuring that the motor can operate stably at lower temperatures.

[0035] The key components of this invention are all made of high-temperature resistant and corrosion-resistant metal materials, especially the materials used for the counterweight 300 and the rotary disc assembly 200. The counterweight 300 is made of a high-density metal alloy, which provides sufficient mass to offset vibrations and withstands the thermal stress generated by high temperatures and long-term operation. The rotary disc assembly 200 is made of a lightweight alloy material, ensuring the stability of the rotary disc assembly 200 during high-speed rotation and reducing the overall weight.

[0036] In the description of this specification, the terms "one embodiment," "some embodiments," "specific embodiment," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0037] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
