Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a special-shaped motor for garden tools. Background Art

[0002] A motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. The motors used in garden tools require special-shaped motors due to the limited space and installation requirements of garden tools, and they need to provide sufficient torque. Conventional motors cannot meet the usage requirements.

[0003] In view of the above-mentioned defects, the designer actively conducts research and innovation in order to create a special-shaped motor for garden tools to make it more valuable for industrial use. Summary of the invention

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide a special-shaped motor for garden tools.

[0005] The utility model discloses a special-shaped motor for garden tools, comprising a stator seat, an adapter seat is fixed above the stator seat, a gear set is installed in the adapter seat, a rotor is movably installed in the gear set and the stator seat through bearings, the end of the rotor is tooth-shaped and meshes with the gear set, and an output rod is fixed on the gear set.

[0006] This garden tool uses a special-shaped motor. The rotor is movably installed in the middle of the stator seat through a bearing. The end of the rotor is engaged with the gear set. After the motor is energized, the rotor rotates, driving the gear set to rotate, and finally the output rod fixed on the gear set rotates to complete the transmission.

[0007] Furthermore, the stator seat is a polygonal structure, with a through hole in the middle for the rotor to pass through, and a plurality of raised positioning platforms on the outer ring of the stator seat. The bolts pass through the positioning platforms and are screwed into the screw holes on the outer ring of the adapter seat.

[0008] The adapter is fixed to the stator seat by bolts to complete the fixed installation of the adapter, making it convenient to adjust the output angle.

[0009] Furthermore, the gear set includes a coaxial gear whose lower end is meshed with the end of the rotor, and an upper end of the coaxial gear is meshed with a transmission tooth fixed on the output rod.

[0010] The coaxial gears mesh with the rotor and the transmission teeth respectively, transmitting the power of the rotor to the transmission teeth, and the output rod installed in the middle of the transmission teeth completes the power output.

[0011] Furthermore, the coaxial gear and the transmission tooth are fixed in the adapter through the shaft and the bearing.

[0012] The coaxial gear and the transmission tooth are concealed in the adapter through the shaft and the bearing for easy rotation.

[0013] Furthermore, an axial flow fan is fixed to the tail end of the rotor by bolts.

[0014] The axial flow fan installed at the tail end of the rotor rotates simultaneously with the rotor to facilitate air circulation and improve heat dissipation efficiency.

[0015] Furthermore, the bottom end of the rotor expands outward and forms an annular support plate, on which there are evenly spaced first protrusions, and the lower end of the magnetic steel is clamped between the first protrusions of the support plate. The outer side of the support plate is wrapped with an outer ring, and the upper cover has a second protrusion that cooperates with the first protrusion. The upper end of the upper cover is an inward-buckled structure, and the upper edge of the outer ring is clamped in the upper cover.

[0016] The rotor forms a mounting ring through the support plate, the upper cover and the outer ring, which is used to fix the magnetic steel.

[0017] Through the above scheme, the present invention has at least the following advantages: this special-shaped motor for garden tools has an external rotor, which can increase the output torque, and at the same time, the output shaft of the motor is conveniently positioned, and the motor is designed into a structural form that is convenient for installation in garden tools, meeting the use requirements of garden tools.
