Description

Technical Field

[0001] This utility model relates to the field of motor rotor technology, and in particular to a motor rotor that prevents the rotor windings from being thrown out. Background Technology

[0002] The motor rotor is also a rotating part in a motor. A motor consists of two parts: a rotor and a stator. It is a device used to convert electrical energy into mechanical energy and mechanical energy into electrical energy. Motor rotors are divided into motor rotors and generator rotors. In the middle of the motor rotor, the windings need to be wound on the rotor core. In order to ensure that the motor rotor can work normally, the windings inside the motor rotor need to be protected to prevent the windings from being thrown out of the rotor after frictional breakage.

[0003] Existing motor rotors have several problems during use. During prolonged operation, the rotor is connected to the motor housing and other components via bearings. Over time, the bearings wear due to continuous friction. This can lead to increased bearing clearance, resulting in increased radial and axial runout of the rotor during rotation. This affects the smooth operation of the motor, causing vibration and noise, and further exacerbates wear on the rotor and other components, reducing the rotor's lifespan. Existing rotors are often secured with bolts, making disassembly relatively difficult and cumbersome, hindering maintenance. To address these issues, an improved and upgraded motor rotor designed to prevent rotor winding ejection is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a motor rotor that prevents the rotor windings from being thrown out, so as to solve the problems mentioned in the background art.

[0005] To solve the above problems, the following technical solutions are provided:

[0007] Furthermore, the outer wall of the motor housing is provided with three sets of hinge seats, each of the three sets of hinge seats is internally threaded with a threaded rod, and one end of the threaded rod is fixedly connected to a threaded knob. One end of the threaded rod is connected to the inside of the heat sink.

[0008] Furthermore, an installation groove is provided inside one side of the motor housing, a sealing ring is provided inside the installation groove and a sealing gasket is provided outside the sealing ring, and a protruding plate is fixedly provided on the outer wall of the snap-fit ​​plate and the protruding plate is located inside the installation groove.

[0009] Furthermore, a threaded post is fixedly provided in the middle of the snap-fit ​​plate, and a snap-fit ​​groove is provided on the inner wall of the threaded post. One end of the rotating shaft is threadedly connected to the threaded post.

[0010] Furthermore, a guide rod is fixedly installed inside the adjusting plate, and a positioning rod is rotatably installed on the outer wall of the guide rod.

[0013] 1. This utility model device includes components such as a rotor shaft, threaded rod, adjusting plate, positioning rod, snap-fit ​​plate, return spring, and limiting cylinder. Rotating three sets of threaded knobs drives the threaded rod to rotate on the hinge seat. Then, manually moving the adjusting plate moves the positioning rod on the guide rod.

When the snap-fit ​​plate is installed with the motor housing, it is sealed by the convex plate, sealing ring, and sealing gasket. This facilitates quick rotor assembly and disassembly while improving the sealing effect. It is easy to operate, extends the rotor's service life, saves time and effort, and has a simple structure.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1 - Figure 4 As shown, this embodiment provides a design for a motor rotor that prevents the rotor winding from being thrown out. It includes a motor housing 1, a heat sink 2 on the rear side of the motor housing 1, and a winding wire 4 on the inner wall of the motor housing 1. A limiting sleeve 5 is attached to the outer wall of the winding wire 4 to limit the winding wire 4 and prevent the winding wire from being thrown out during rotation. A rotating shaft 6 is provided inside the motor housing 1, and a rotor shaft 7 is sleeved on the outer wall of the rotating shaft 6. A positioning component 9 is provided on one side of the outer wall of the rotating shaft 6 and located on the rotor shaft 7. The positioning component 9 includes an adjusting plate 91, a positioning rod 93, and a return spring 95. A snap-fit ​​plate 8 is provided on one side of the rotating shaft 6, and a cooling fan 10 is provided on the outer side of the snap-fit ​​plate 8.

[0023] Preferably, the outer wall of the motor housing 1 is provided with three sets of hinge seats 3, each set of hinge seats 3 is internally threaded with a threaded rod 32, and one end of the threaded rod 32 is fixedly connected to a threaded knob 31. One end of the threaded rod 32 is connected to the inside of the heat sink 2. A mounting groove 16 is opened inside one side of the motor housing 1. A sealing ring 15 is provided inside the mounting groove 16, and a sealing gasket 14 is provided outside the sealing ring 15. A protruding plate 13 is fixedly provided on the outer wall of the snap-fit ​​plate 8 and is located inside the mounting groove 16. A threaded post 11 is fixedly provided in the middle of the snap-fit ​​plate 8. A snap-fit ​​groove 12 is opened on the inner wall of the threaded post 11. One end of the rotating shaft 6 is threadedly connected to the threaded post 11.

[0024] By pressing the sealing ring 15 and sealing gasket 14 on the mounting groove 16 with the protruding plate 13 on the snap-fit ​​plate 8, the snap-fit ​​plate 8 is relatively sealed to the motor housing 1 during installation. This facilitates the relative sealing between the heat sink 2 and the motor housing 1 during installation, prevents dust from entering and affecting use, and improves its sealing effect.

[0025] Preferably, a guide rod 92 is fixedly installed inside the adjusting plate 91, and a positioning rod 93 is rotatably installed on the outer wall of the guide rod 92. One end of the positioning rod 93 is fixedly connected to a snap-fit ​​block 94, and a return spring 95 is sleeved on the outer wall of the positioning rod 93. One end of the return spring 95 is snapped into the inside of the limiting cylinder 96. The limiting cylinder 96 is fixedly installed on the outer wall of the rotating shaft 6, and one end of the snap-fit ​​block 94 is installed on the snap-fit ​​groove 12.

[0026] By manually moving the adjusting plate 91, the adjusting plate 91 drives the positioning rod 93 on the guide rod 92 to move. At the same time, one end of the adjusting plate 91 presses against the limiting cylinder 96. The positioning rod 93 is compressed by the return spring 95, so that the positioning rod 93 drives the snap-fit ​​block 94 to be misaligned from the snap-fit ​​groove 12 on the threaded column 11, which is convenient for disassembly.

[0027] The working principle and process of this utility model: After long-term use, the internal rotor of the motor will experience wear and tear, requiring disassembly by the operator. First, the operator rotates the three sets of threaded knobs 31 to drive the threaded rod 32 to rotate on the hinge seat 3, thus removing the heat sink 2. Then, by manually moving the adjusting plate 91, the operator moves the positioning rod 93 on the guide rod 92. At the same time, one end of the adjusting plate 91 presses against the limiting cylinder 96, and the positioning rod 93 is compressed by the return spring 95. As a result, the positioning rod 93 causes the locking block 94 to be displaced from the locking groove 12 on the threaded post 11. Then, the operator moves the rotating shaft 6 away by rotating the threaded post 11 on the snap-fit ​​plate 8, removes the snap-fit ​​plate 8, and finally pulls the rotor shaft 7 on the rotating shaft 6 out of the motor housing 1. The operation is easy and facilitates rotor maintenance to prevent wear. During installation, the adjusting plate 91 drives the snap-fit ​​block 94 on the positioning rod 93 to snap onto the snap-fit ​​groove 12. By pressing the sealing ring 15 and sealing gasket 14 on the mounting groove 16 with the protruding plate 13 on the snap-fit ​​plate 8, the snap-fit ​​plate 8 is relatively sealed to the motor housing 1 during installation. Finally, the heat sink 2 is connected, which facilitates quick rotor disassembly while effectively sealing the rotor.
