Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a stator and rotor of a vibration motor. Background Technique

[0002] The motor stator is the stationary part of a motor or generator, while the rotor core is the rotating part. The stator consists of three parts: the stator core, the stator winding, and the frame, and its main function is to generate a rotating magnetic field. The rotor core is cut by magnetic lines of force in the rotating magnetic field, thereby generating (outputting) current. The interaction between the stator and rotor cores realizes the energy conversion of the motor.

[0003] For example, the existing patent (publication number: CN212258605U) discloses a motor rotor and its motor structure, including a rotor core, on the surface of which a stator is fixedly connected, on the surface of which a housing is fixedly connected. The housing includes a base layer, on the top of which an anti-corrosion layer is fixedly connected, on the top of which a wear-resistant layer is fixedly connected, on the bottom of which a housing is fixedly connected, on the bottom of which a waterproof layer is fixedly connected. Rotor core windings are fixedly connected to both sides of the rotor core, a rotating shaft penetrates through the inner cavity of the rotor core, and a commutator is arranged on the surface of the rotor core.

[0004] However, the above-designed motor rotor and its motor structure still have some disadvantages in actual use: Although the motor rotor core and its motor structure can have the advantages of wear resistance and anti-corrosion through the cooperation of the housing, the base layer, the anti-corrosion layer, the wear-resistant layer, the housing, and the waterproof layer, and solve the problems that the existing motors have poor wear resistance and anti-corrosion properties, and the outer shell is easily damaged after long-term use, thus affecting the service life of the motor. However, when the motor rotor core rotates, it will generate vibrations in the horizontal direction, which are caused by the unbalance in the static balance of the rotor core. The vibrations will cause friction between the rotor core and the stator of the motor, resulting in motor damage and affecting the service life of the motor.

[0005] Therefore, we designed a stator and rotor of a vibration motor to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a stator and rotor of a vibration motor to solve the problems raised in the above background technique.

[0007] To solve the above technical problems, a stator and rotor of a vibration motor provided by the utility model includes a rotor core, grooves are provided at both ends of the rotor core, a plurality of clamping blocks are arranged in the grooves, and a shock absorption assembly is arranged at one end of the rotor core;

[0008] The shock-absorbing assembly includes two connecting plates, and four connecting rods are arranged between the two connecting plates. Rotating shafts are arranged on both side surfaces of the connecting plates. One end of each connecting rod is rotatably connected to the surface of the rotating shaft, and the other ends of the four connecting rods are commonly connected to a pin shaft. A damper is arranged between the interiors of the two connecting plates.

[0009] Further, one end of the connecting plate abuts against one end of the rotor core, and an end cover is arranged at the other end of the connecting plate. The surface of the end cover abuts against the surface of the other end of the connecting plate, so that the shock-absorbing assembly can be fixed to one end of the rotor core.

[0010] Further, a stator is arranged on the surface of the rotor core, and sealing rings are arranged at both ends of the stator.

[0011] Further, a housing is sleeved on the surface of the stator. The stator includes a base layer, an anti-corrosion layer, a wear-resistant layer, and an anti-rust layer, which are used to protect the rotor core and the stator.

[0012] Further, sliding grooves are arranged around the inner wall of the housing, and sliding strips are correspondingly arranged on the outer surface of the stator. The sliding strips are slidably connected in the sliding grooves, which is convenient for connecting the stator to the inside of the housing.

[0013] Further, a plurality of dowel pins are arranged around one end of the rotor core, and a plurality of slots are correspondingly arranged at one end of the housing. The dowel pins are inserted into the slots.

[0014] Further, one end of the clamping block is fixedly connected to the inside of the housing, and the other end of the clamping block is placed in the groove and has a certain distance from the surface of the rotor core.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: By arranging a shock-absorbing assembly at one end of the rotor core, the connecting plates of the shock-absorbing assembly respectively abut against the surface of one end of the rotor core and the surface of the end cover, which is used to relieve the vibration generated during the rotation of the rotor core.

While determining the installation position of the rotor core, it does not affect the rotation of the rotor core.

At the same time, the stator is slidably inserted into the inside of the housing. Under the action of the sliding strips and the slots, the connection is smoother. Then, the dowel pins are inserted into the slots to make the device completely installed. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] During specific implementation, by arranging a shock absorption assembly at one end of the rotor core 1, the connecting plates 5 of the shock absorption assembly respectively abut against the surface of one end of the rotor core 1 and the surface of the end cover 4, which is used to relieve the vibration generated during the rotation of the rotor core 1. At the same time, grooves 2 are arranged on the surface of the rotor core 1, a plurality of grooves 2 are arranged in the grooves 2 and one end surface of the grooves 2 does not contact the surface of the rotor core 1. While determining the installation position of the rotor core 1, it does not affect the rotation of the rotor core 1.

[0025] Refer to Figures 1-4 As shown, a stator 10 is provided on the surface of the rotor core 1. Sealing rings 11 are provided at both ends of the stator 10. A housing 12 is sleeved on the surface of the stator 10. Sliding grooves 13 are provided around the inner wall of the housing 12.

The dowel pins 16 are inserted into the slots 15.

[0026] In specific implementation, by providing the sealing rings 11 at both ends of the stator 10, it is ensured that the lubricating oil between the stator 10 and the rotor core 1 will not leak. At the same time, the stator 10 is slidably inserted into the interior of the housing 12. Under the action of the sliding bars 14 and the slots 15, the connection is smoother.

The vibration will cause friction between the rotor core 1 and the stator 10 of the motor, resulting in motor damage and affecting the service life of the motor. By providing a shock-absorbing component at one end of the rotor core 1, the connecting plates 5 of the shock-absorbing component are respectively abutted against the surface of one end of the rotor core 1 and the surface of the end cover 4, which is used to relieve the vibration generated during the rotation of the rotor core 1.

[0030] By setting sealing rings 11 at both ends of the stator 10, it is ensured that the lubricating oil between the stator 10 and the rotor core 1 will not leak out. At the same time, the stator 10 is slidably inserted into the interior of the housing 12. Under the action of the slide bar 14 and the slot 15, the connection is made smoother. Then, the dowel pin 16 is inserted into the slot 15 to complete the installation of the device.
