Description

Technical Field

[0001] This utility model relates to the technical field of rotor end plate tools, and in particular to a unidirectional rotating rotor end plate with vortex fan blades. Background Technology

[0002] During the operation of motor equipment, efficient heat dissipation of the rotor and reasonable rotation control are crucial to ensuring motor performance and extending its service life. Traditional rotor end plates have certain limitations in functional design and cannot fully meet the current demand for high performance and high stability of motors.

[0003] From a heat dissipation perspective, ordinary rotor end plates can rotate in both directions with a constant airflow, but lack effective heat dissipation enhancement structures. When the motor is running, the rotor generates a large amount of heat due to current passing through the windings and mechanical friction. If this heat cannot be dissipated in time, the rotor temperature will continue to rise. Excessive temperature will not only increase the winding resistance, increase energy loss, and reduce motor efficiency, but may also affect the performance of the magnets, causing a decrease in the motor's output torque and power, and in severe cases, even motor failure. Although some existing rotor end plates have simple heat sinks, the shape, layout, and size of the heat sinks are often not optimized, and they cannot efficiently guide airflow to form an effective cooling airflow during rotor rotation, resulting in unsatisfactory heat dissipation. Therefore, the above problems need to be addressed. Utility Model Content

[0006] Preferably, the heat dissipation mechanism includes turbine fan blades mounted on the output shaft and an exhaust ring mounted on the front end of the end plate housing, wherein multiple exhaust slots are equidistantly opened on the inner side of the exhaust ring.

[0007] Preferably, the limiting mechanism includes a mounting block obliquely fixed to the top of the end plate housing and a limiting ring mounted on the output shaft. Multiple sets of oblique limiting blades are equidistantly mounted on the side of the limiting ring. A limiting block is hinged to the bottom of the mounting block. Both the limiting block and the limiting blades have abutting oblique sections. A torsion spring is installed at the hinge of the mounting block and the limiting block.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example: See Figure 1-6 This utility model discloses a unidirectional rotating rotor end plate with vortex fan blades, comprising a rotor housing 1 and an end plate housing 2. The rotor housing 1 facilitates the installation of a rotor 3; the end plate housing 2 facilitates the installation of a limiting mechanism; the rotor 3 is installed inside the rotor housing 1, and the rotor 3 facilitates the rotation of an output shaft 4; the output shaft 4 is installed at the front end of the rotor 3, and the output shaft 4 facilitates the rotation of the limiting mechanism and the turbine fan blades 5; the output shaft 4 is equipped with a limiting mechanism and a heat dissipation mechanism; the end plate housing 2 is equipped with a dustproof mechanism; the heat dissipation mechanism includes the turbine fan blades 5 installed on the output shaft 4 and an exhaust ring 6 installed at the front end of the end plate housing 2; the turbine fan blades 5 facilitate heat dissipation and cooling of the device; the exhaust ring 6 facilitates the increase of airflow in conjunction with the turbine fan blades 5; multiple exhaust grooves 7 are equidistantly opened on the inner side of the exhaust ring 6, and the exhaust grooves 7 facilitate the coordination with the exhaust ring 6.

[0022] In this utility model, the limiting mechanism includes a mounting block 8 obliquely fixed to the inner top of the end plate housing 2 and a limiting ring 9 mounted on the output shaft 4. The limiting ring 9 facilitates the installation of limiting blades 10. Multiple sets of oblique limiting blades 10 are equidistantly mounted on the side of the limiting ring 9, which facilitates the engagement of the limiting block 11. The bottom end of the mounting block 8 is hinged to the limiting block 11, which prevents the limiting blades 10 from rotating in the opposite direction. Both the limiting block 11 and the limiting blades 10 have abutting oblique sections, and a torsion spring 12 is installed at the hinge of the mounting block 8 and the limiting block 11. 2. Facilitates the reset of the limiting block 11; a limiting plate is fixedly attached to one side of the bottom end of the mounting block 8. The dustproof mechanism includes a first filter 13 installed at the rear end of the limiting mechanism and a second filter 14 installed at the front end of the limiting mechanism. The first filter 13 and the second filter 14 facilitate the prevention of dust from entering the device. The first filter 13 and the second filter 14 are connected to the inner side of the end plate housing 2, and the inner rings of the first filter 13 and the second filter 14 are rotatably connected to the outer ring surface of the output shaft 4. The turbine fan blade 5, the limiting ring 9, the second filter 14 and the first filter 13 are installed on the output shaft 4 in the following order from front to back:

[0023] Working principle: When using this utility model, the device is first powered on. After the device is powered on, the copper wire and magnetic ring drive the rotor 3 to rotate the output shaft 4, which in turn drives the turbine fan blade 5 to rotate, drawing out the hot air inside the device. At the same time, the exhaust ring 6 and exhaust slot 7 work together to expel the hot air at the fastest speed, thereby achieving a rapid cooling effect on the device. During the rotation, the first filter 13 and the second filter 14 can prevent dust from entering the device. During the rotation of the output shaft 4, the limiting blade 10 rotates, continuously pushing the limiting block 11 to rotate. Then the torsion spring 12 drives the limiting block 11 to reset. When the device reverses, the limiting blade 10 and the limiting block 11 abut against each other. Since the limiting plate cannot rotate, the output end of the limiting block 11 stops rotating, thereby realizing the unidirectional rotation of the device.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
