Description

Technical Field

[0001] This utility model relates to the field of motor technology for garden machinery, and in particular to a high-efficiency, low-vibration, and low-noise motor for garden machinery. Background Technology

[0002] With the acceleration of urbanization and the increasing demands for quality of life, landscaping plays an increasingly important role in modern urban construction. As the core equipment for landscaping operations, garden machinery is used in various stages, including pruning, cleaning, and planting. Among these, the motor, as the core power component, plays a decisive role in the overall performance of the equipment. An ideal garden machinery motor not only needs to have high-efficiency power output but also meet the requirements of low vibration and low noise to improve operational comfort and work efficiency. However, current garden machinery motor technology still faces many technical bottlenecks in practical applications, making it difficult to fully meet the increasingly diverse needs of garden operations. For example:

[0003] Lack of vibration control: During operation, garden machinery motors are prone to significant vibration due to the inertial force generated by the rotation of the output shaft, coupled with uneven mechanical load. This not only affects the stability and operational comfort of the equipment but also accelerates the wear of motor components and shortens their service life.

[0004] Inadequate noise control: The noise sources of garden machinery motors mainly include mechanical vibration noise, motor operation noise, and cooling gas flow noise. While traditional technologies have improved the sound insulation design of the motor housing, they have paid less attention to addressing the high-frequency noise generated by cooling airflow and gas emission noise. The use of such equipment in garden environments causes noise pollution to operators and the surrounding environment, affecting user experience and environmental performance.

[0005] Insufficient efficiency and environmental adaptability: Garden machinery is frequently used in outdoor environments and is easily affected by external factors such as dust and moisture. The inadequacy of existing motor protection design makes it easy for dust to enter and cause wear on components such as output shafts and bearings, reducing the efficiency of the equipment. At the same time, the lack of effective modular structure design makes the maintenance and repair of motors more difficult, further increasing the operating cost of the equipment.

[0006] Therefore, it is essential to invent a high-efficiency, low-vibration, and low-noise motor for garden machinery. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model provides a high-efficiency, low-vibration, and low-noise motor for garden machinery, solving the issues of high noise levels, significant vibrations, and reduced efficiency due to environmental factors in existing garden machinery motors. The high-efficiency, low-vibration, and low-noise motor for garden machinery includes a stable mounting bracket, a stable base, a motor housing, an output shaft, a stable protective cover, a fan housing, a junction box, and lifting lugs. The stable base is fixedly mounted on the surface of the stable mounting bracket, and the motor housing is fixedly mounted on the surface of the stable base. The output shaft is fixedly mounted on the front end of the rotor inside the motor housing. The stable protective cover is fixedly mounted on the front end of the motor housing, and the fan housing is fixedly mounted on the rear end of the motor housing. The junction box and lifting lugs are fixedly mounted on the surface of the motor housing.

[0008] The motor housing includes a shell, an air chamber, an air outlet pipe, an air outlet silencer pipe, and an auxiliary air outlet structure. The shell is fixedly installed on the surface of the stable base, and the air chamber is fixedly installed on both sides of the shell.

The dustproof support cover is fixedly installed at the top end of the base support frame by connecting bolts, and the second stabilizing bearing is fixedly installed at the middle position of the dustproof support cover, with an output shaft slidably installed inside it.

[0010] The motor housing has a double-layered metal shell, with sound-absorbing cotton filling the interlayer. The air chamber consists of two outwardly extending rectangular spaces, and the exhaust pipe has two bent pipes with the outlet facing rearward and extending diagonally upward. The exhaust silencer consists of two sets of gas silencers, and the auxiliary exhaust structure has two sets of cylindrical shells. An auxiliary exhaust fan is installed inside the auxiliary exhaust structure, serving the following functions: ① Protecting performance and improving efficiency: The fan casing inside the housing guides the flow of cooling gas, cooling the rotor and stator inside the motor, reducing operating temperature, and preventing high temperatures from affecting motor performance.

[0011] The internal support frame of the stabilizing protective cover uses a set of annular metal seats, and the first stabilizing bearing uses a set of ceramic bearings. The center of the first stabilizing bearing is collinear with that of the rotor bearing. The dustproof support cover uses a cover-shaped metal structure, and the second stabilizing bearing uses a set of dustproof high-precision ball bearings. The center of the second stabilizing bearing is collinear with that of the first stabilizing bearing and the rotor bearing. This has the following functions: ① Improved working efficiency: The stabilizing protective cover effectively prevents external dust or particles from entering the motor by fixing and supporting the output shaft, thereby avoiding impurities from interfering with the rotation of the bearings, output shaft, and rotor, ensuring stable operation of the motor under high load, and improving working efficiency.
