A rotor shaft system structure 100, a motor, and an electric appliance according to some embodiments of the present embodiment are described below with reference to fig. 1 and 2.

As shown in fig. 1 and fig. 2, a first aspect of the present embodiment provides a rotor shaft system structure 100, which includes a rotating shaft 110, a blocking component 120, a supporting assembly 130, and an elastic component 140; the blocking member 120 is connected to the rotating shaft 110 and protrudes from the surface of the rotating shaft 110 in the radial direction of the rotating shaft 110; the supporting component 130 is connected with the rotating shaft 110, the supporting component 130 comprises a cylinder 132, and the rotating shaft 110 can rotate relative to the cylinder 132; the elastic member 140 is disposed along the axial direction of the rotating shaft 110, a first end of the elastic member 140 abuts against the blocking member 120, and a second end of the elastic member 140 abuts against the cylinder 132.

In this embodiment, the rotor shaft system structure 100 includes a rotating shaft 110, a blocking member 120, a support assembly 130, and an elastic member 140. The blocking member 120 is coupled to the rotation shaft 110 to protrude from a surface of the rotation shaft 110 in a radial direction of the rotation shaft 110, so that the blocking member 120 is mounted. The supporting component 130 is connected with the rotating shaft 110, so that the supporting component 130 can support the rotating shaft 110, and the stability of the rotating shaft 110 during rotation is ensured, the supporting component 130 comprises a cylinder 132, and the rotating shaft 110 can rotate relative to the cylinder 132; the elastic member 140 is disposed along the axial direction of the rotating shaft 110, a first end of the elastic member 140 abuts against the blocking member 120, and a second end of the elastic member 140 abuts against the cylinder 132, so that the elastic member 140 is disposed between the cylinder 132 and the blocking member 120 to achieve the installation of the blocking member 120. By disposing the elastic member 140 between the blocking member 120 and the cylinder 132, when the motor is started, since two ends of the elastic member 140 abut against the blocking member 120 and the cylinder 132, the elastic member 140 has elasticity, which enables the elastic member 140 to apply an axial pressure to the cylinder 132, so that the cylinder 132 has an initial pre-pressure at the stage of starting the rotation of the rotating shaft 110, thereby preventing the cylinder 132 from being in an irregular free sliding state on the rotating shaft 110, and eliminating the play by preventing the cylinder 132 from moving in the axial direction relative to the rotating shaft 110, thereby reducing the noise caused by the play.

Specifically, the elastic member 140 is a spring, a first end of the spring abuts against the blocking member 120, and a second end of the spring abuts against the cylinder 132, so that the spring can apply an axial pressure to the cylinder 132 when the motor is started.

Further, the magnitude of the initial preload applied to the cylinder 132 by the elastic member 140 can be adjusted according to the magnitude of the elastic force of the elastic member 140. The initial pre-pressure of the motor in the beginning of rotation is ensured, the cylinder 132 is prevented from being abraded and generated due to the fact that the cylinder 132 is in an irregular free sliding state, the problem that abnormal noise is generated in the beginning of rotation of the motor is solved, the abnormal noise generated by the cylinder 132 when the motor is started and stopped is effectively avoided, and the service life of the rotor shafting structure 100 is prolonged.

Further, when the motor is in a loaded operating state, that is, when the rotating shaft 110 rotates normally, and an axial load is generated under the action of a load of the motor, the generated axial load can play a role of axial pre-pressing, and further an axial pre-pressing force can be generated to the cylinder 132, the elastic member 140 and the axial load provided by the load jointly generate a pre-pressing force function, and meanwhile, the axial pre-pressing force is applied to the cylinder 132, so that the cylinder 132 is in a stable operating state, the operation of the motor is more stable, and noise generated by the motor can be further reduced.

Specifically, by adjusting the stiffness of the elastic member 140, the initial pre-pressure applied to the cylinder 132 by the elastic member 140 can be adjusted at the stage when the rotor shafting structure 100 starts to rotate, so as to ensure that the elastic member 140 can achieve the stability of reducing noise.

Specifically, the motor can produce axial load when normally working, and the axial load that produces can play the effect of axial pre-compaction, exerts axial pretightning force for barrel 132, makes barrel 132 be in normal rolling state, and the state is good, and no abnormal noise appears. However, when the motor is started, no axial pre-pressure is applied to the cylinder 132, so that the cylinder 132 slides freely, and the generated noise is obvious. The elastic member 140 is arranged on the cylinder 132 and the blocking component 120, that is, the first end of the elastic member 140 abuts against the blocking component 120, and the second end of the elastic member 140 abuts against the cylinder 132, so that the centering performance of the supporting component 130 when the rotating shaft 110 rotates can be ensured, the stress of the cylinder 132 is more uniform, the operation is stable, and the stability of the rotor shaft system structure 100 during operation can be improved; meanwhile, the initial pre-pressure when the motor is started is ensured, the supporting component 130 is prevented from being in an irregular free sliding state, and abnormal noise generated by the supporting component 130 when the motor starts to rotate is effectively avoided.
