Description

Technical Field

[0001] The utility model relates to the technical field of stator shafts, in particular to a stator shaft capable of damping vibration. Background Art

[0002] The stator shaft is a core component in the motor. It supports and fixes the stator core. The stator core is the part of the motor used to generate the magnetic field, while the stator shaft ensures that it can operate stably. When the motor is working, the stator shaft will also bear a certain torque and load, so its quality and performance have an important impact on the overall operation of the motor.

[0003] The current stator shaft has a poor shock-absorbing effect when in use and cannot disperse and absorb vibration energy well, so it is impossible to maintain the stability of the stator shaft, which will affect the service life of the stator shaft. Therefore, we propose a shock-absorbing stator shaft to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 In the utility model, a shock-absorbing stator shaft comprises a stator shaft body 1, an annular plate 2 is provided on the outside of the stator shaft body 1, two groups of pillars 14 are fixedly connected to the inner wall of the annular plate 2, and one end of each group of pillars 14 close to each other is fixedly connected to a connecting plate 15, and one side of each connecting plate 15 is provided with two groups of jacks 13, and a plug rod 16 is inserted in the inside of each jack 13, and the ends of the two groups of plug rods 16 close to each other are respectively fixedly connected to a top plate 12, and the outer surface of the stator shaft body 1 is fixedly connected to a first bearing 7, and the outer surface of the first bearing 7 is fixedly connected to two groups of fixed cylinders 9, and the inner wall of each fixed cylinder 9 is fixedly connected to a spring 10, and the end of each group of springs 10 away from each other is fixedly connected to a push rod 11, and the end of each group of push rods 11 away from each other is respectively connected to the side of each group of top plates 12 close to each other.

[0021] Two groups of first threaded cylinders 19 are fixedly connected to the outer surface of the first bearing 7, and the inner wall of the annular plate 2 is fixedly connected to the second threaded cylinder 17. The inner wall of each first threaded cylinder 19 and the inner wall of each second threaded cylinder 17 are commonly threadedly connected with a threaded rod 18. The thread direction of the threaded rod 18 is the same as the thread direction of the first threaded cylinder 19 and the second threaded cylinder 17, thereby ensuring that the threaded rod 18 can connect the first threaded cylinder 19 and the second threaded cylinder 17.

[0022] A group of fixing plates 8 are fixedly connected to the upper surface and the bottom surface of the annular plate 2. A fixing hole 3 is opened on one side of each fixing plate 8. The fixing plates 8 are used to facilitate the staff to fix the annular plate 2, which can enhance the stability of the annular plate 2 in reinforcing the stator shaft body 1.

[0023] A second bearing 6 is fixedly connected to the outer surface of the stator shaft body 1, and two groups of stabilizing rods 4 are fixedly connected to the outer surface of the second bearing 6. An arc plate 5 is fixedly connected to one end of each group of stabilizing rods 4 that is away from each other. By utilizing the cooperation between the stabilizing rods 4 and the arc plate 5, the bottom of the stator shaft body 1 can be stabilized to prevent the bottom from deviating.

[0024] A side surface of each connecting plate 15 close to the stator shaft body 1 is in contact with a side surface of each top plate 12 away from the stator shaft body 1 . The connecting plate 15 is in close contact with the top plate 12 , thereby ensuring the stability of the top plate 12 when moving.

[0025] One end of each push rod 11 close to the stator shaft body 1 extends into the interior of the fixing tube 9. When the spring 10 is extended, the push rod 11 will not separate from the fixing tube 9, thereby preventing the push rod 11 from being pushed out of the fixing tube 9 when the spring 10 is compressed and expanded.

[0026] The working principle of the utility model is as follows: when in use, the annular plate 2 can be sleeved on the outside of the stator shaft body 1, and then the top plate 12 can be pressed, the top plate 12 will push the push rod 11 to move, the push rod 11 will enter the inside of the fixed tube 9, and at the same time, the spring 10 will be compressed, and then the connecting plate 15 and the top plate 12 are aligned, and the top plate 12 is pressed and held, and the elasticity of the spring 10 is used to push the push rod 11, and the insertion rod 16 will enter the inside of the insertion hole 13, and finally the threaded rod 18 is connected to the first threaded tube 19 and the second threaded tube 17. When the stator shaft body 1 vibrates, the fixed tube 9 will be pushed, and the spring 10 will shrink. When the spring 10 shrinks, it will absorb the vibration force, thereby ensuring the stability of the stator shaft body 1 and extending its service life.
