As an efficient kinetic energy storage device, the motor flywheel is widely used in various fields, bringing a more stable and reliable operation mode to the system.

[0004] However, in the above-mentioned prior art, the kinetic energy loss of the existing flywheel with a motor shaft is relatively large during rotation, resulting in poor energy storage effect of the flywheel. Content of the Utility Model

[0005] The purpose of the utility model is to provide a flywheel with a motor shaft, which solves the technical problem that the kinetic energy loss of the existing flywheel with a motor shaft is relatively large during rotation, resulting in poor energy storage effect of the flywheel in the prior art.

[0006] To achieve the above purpose, a flywheel with a motor shaft adopted by the utility model comprises a vacuum shell, an air extraction pipe, an air extraction cover and a rotating assembly. The rotating assembly comprises a first fixing block, a first radial bearing, a second fixing block, a second radial bearing, a rotating shaft, a flywheel and an auxiliary component.

The first fixed ring is fixedly connected to the vacuum shell and is located inside the vacuum shell, and the first fixed ring is located below the axial magnetic levitation bearing. The second fixed ring is fixedly connected to the vacuum shell and is located inside the vacuum shell. The reciprocal two-way motor stator is detachably connected to the fixed ring and is located between the first fixed ring and the second fixed ring.

[0009] Among them, the auxiliary component further includes a motor rotor. The motor rotor is detachably connected to the rotating shaft and is located inside the rotating shaft, and the motor rotor corresponds to the reciprocal two-way motor stator.

The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0020] The first embodiment of the present application is as follows:

[0021] Please refer to Figures 1 to 3 , where Figure 1 is a schematic structural diagram of the first embodiment of the present invention, Figure 2 is a front view of the first embodiment of the present invention, Figure 3 is of the present invention Figure 2 structural cross-sectional view taken along line A-A.

[0022] The utility model provides a flywheel with a motor shaft, which includes a vacuum shell 101, an air extraction pipe 102, an air extraction cover 103, a first fixing block 104, a first radial bearing 105, a second fixing block 106, a second radial bearing 107, a shaft 108, a flywheel 109, an axial magnetic levitation bearing 110, a first fixing ring 111, a second fixing ring 112, a reciprocating two-way motor stator 113 and a motor rotor 114. The foregoing solution solves the problem in the prior art that the kinetic energy loss is relatively large when the existing flywheel with a motor shaft rotates, resulting in poor energy storage effect of the flywheel 109.

[0023] For this specific embodiment, the air extraction pipe 102 is fixedly connected to the vacuum shell 101 and is located on the outer surface of the vacuum shell 101. The air extraction cover 103 is detachably connected to the air extraction pipe 102 and is located at one end of the air extraction pipe 102. The first fixing block 104 is fixedly connected to the vacuum shell 101 and is located inside the vacuum shell 101. The first radial bearing 105 is detachably connected to the first fixing block 104 and is located inside the first fixing block 104. The second fixing block 106 is fixedly connected to the vacuum shell 101 and is located inside the vacuum shell 101. The second radial bearing 107 is detachably connected to the second fixing block 112 and is located inside the second fixing block 106. The shaft 108 is rotatably connected to the first radial bearing 105 and is located inside the first radial bearing 105 and the second radial bearing 107. The flywheel 109 is fixedly connected to the shaft 108 and wraps the shaft 108. The first fixing block 104 and the second fixing block 106 fix the first radial bearing 105 and the second radial bearing 107 on the inner wall of the vacuum shell 101. Open the air extraction cover 103 to connect the air extraction pipe 102 to an external vacuum pumping device, and pump the inside of the vacuum shell 101 to a vacuum, so that in a vacuum environment, in cooperation with the first radial bearing 105 and the second radial bearing 107, the kinetic energy loss during the rotation of the shaft 108 is greatly reduced.

[0024] Among them, the axial magnetic levitation bearing 110 is fixedly connected to the vacuum shell 101 and is located inside the vacuum shell 101, and the axial magnetic levitation bearing 110 is located below the flywheel 109. The axial magnetic levitation bearing 110 can fix the axial position of the flywheel 109 to prevent the flywheel 109 from contacting the vacuum shell 101, so that the friction force received by the flywheel 109 is reduced, and the power loss is further reduced.

[0025] Secondly, the first fixing ring 111 is fixedly connected to the vacuum housing 101 and is located inside the vacuum housing 101. Moreover, the first fixing ring 111 is positioned below the axial magnetic levitation bearing 110. The second fixing ring 112 is fixedly connected to the vacuum housing 101 and is located inside the vacuum housing 101. The reciprocal two-way motor stator 113 is detachably connected to the fixing ring and is located between the first fixing ring 111 and the second fixing ring 112. The first fixing ring 111 and the second fixing ring 112 fix the position of the reciprocal two-way motor stator 113 within the vacuum housing 101.

[0026] Meanwhile, the motor rotor 114 is detachably connected to the rotating shaft 108 and is located inside the rotating shaft 108. Moreover, the motor rotor 114 corresponds to the reciprocal two-way motor stator 113. When the reciprocal two-way motor stator 113 is energized to generate a magnetic field, it interacts with the conductors on the motor rotor 114, thereby causing the conductors on the motor rotor 114 to generate induced current, and further generating torque to drive the rotation of the motor rotor 114, thus driving the rotation of the rotating shaft 108. At the same time, when the rotating shaft 108 rotates, it will drive the flywheel 109 to rotate. The kinetic energy loss during the rotation of the flywheel 109 is relatively small, and it can store more kinetic energy.

[0027] Using a flywheel with a motor shaft in this embodiment, by setting a vacuum shell 101, an air extraction pipe 102, an air extraction cover 103, a first fixing block 104, a radial bearing 105, a second fixing block 106, a radial bearing 107, a shaft 108, a flywheel 109, an axial magnetic levitation bearing 110, a first fixing ring 111, a second fixing ring 112, a reciprocating two-way motor stator 113 and a motor rotor 114, the air extraction pipe 102 is fixedly connected to the vacuum shell 101 and is located on the outer surface of the vacuum shell 101. The air extraction cover 103 is detachably connected to the air extraction pipe 102 and is located at one end of the air extraction pipe 102. The first fixing block 104 is fixedly connected to the vacuum shell 101 and is located inside the vacuum shell 101. The radial bearing 105 is detachably connected to the first fixing block 104 and is located inside the first fixing block 104. The second fixing block 106 is fixedly connected to the vacuum shell 101 and is located inside the vacuum shell 101. The radial bearing 107 is detachably connected to the second fixing block 112 and is located inside the second fixing block 106. The shaft 108 is rotatably connected to the radial bearing 105 and is located inside the radial bearing 105 and the radial bearing 107. The flywheel 109 is fixedly connected to the shaft 108 and wraps the shaft 108. When the reciprocating two-way motor stator 113 is energized to generate a magnetic field, it interacts with the conductor on the motor rotor 114, so that an induced current is generated in the conductor on the motor rotor 114, and then a torque is generated to drive the motor rotor 114 to rotate, thereby driving the shaft 108 to rotate. At the same time, when the shaft 108 rotates, it will drive the flywheel 109 to rotate. The kinetic energy loss of the flywheel 109 during rotation is small, and it can store more kinetic energy. Open the air extraction cover 103 to connect the air extraction pipe 102 to an external vacuum pumping device, and pump the inside of the vacuum shell 101 to a vacuum, so that in a vacuum environment, in cooperation with the radial bearing 105 and the radial bearing 107, the kinetic energy loss during the rotation of the shaft 108 is greatly reduced. The axial magnetic levitation bearing 110 can fix the axial position of the flywheel 109 to prevent the flywheel 109 from contacting the vacuum shell 101, so that the friction force received by the flywheel 109 is reduced, and the power loss is further reduced, thus solving the problem that the kinetic energy loss of the existing flywheel with a motor shaft is large during rotation, resulting in poor energy storage effect of the flywheel 109.

[0028] The second embodiment of this application is as follows:

[0029] On the basis of the first embodiment, please refer to Figures 4 to 5 , Figure 4 is the front view of the second embodiment of the present utility model, Figure 5 is the Figure 4 structural sectional view taken along line B-B of

[0030] The utility model provides a flywheel with a motor rotating shaft, further comprising a connecting plate 201, a connecting hole 202 and a sealing ring 203. The foregoing solution solves the problem of poor sealing when the air extraction pipe 102 is connected to an external vacuum pumping device in the prior art.

[0031] Wherein, the connecting plate 201 is fixedly connected to the air extraction pipe 102 and wraps the air extraction pipe 102. The connecting hole 202 is arranged on the surface of the connecting plate 201 and penetrates through the connecting plate 201. The sealing ring 203 is fixedly connected to the air extraction pipe 102 and is located inside the air extraction pipe 102. A fixing nail is passed through the connecting hole 202 to connect the connecting plate 201 to the output end of the external vacuum pumping device, and the cooperation with the sealing ring 203 can increase the sealing performance during vacuum pumping.

[0032] When using the flywheel with a motor rotating shaft of this embodiment, by setting the connecting plate 201, the connecting hole 202 and the sealing ring 203, and passing a fixing nail through the connecting hole 202 to connect the connecting plate 201 to the output end of the external vacuum pumping device, the gap between the air extraction pipe 102 and the external vacuum pumping device is reduced, and the cooperation with the sealing ring 203 can effectively increase the sealing performance during vacuum pumping, thereby solving the problem of poor sealing when the air extraction pipe 102 is connected to the external vacuum pumping device.
