Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of motor rotors, in particular to a motor rotor and a motor. Background Art
[0002] When the main rotor rotates at high speed, the shaft deflects and deforms when its speed approaches the critical speed. This can even lead to mechanical damage due to resonance. The rotor's lateral vibration has multiple natural frequencies, and therefore multiple corresponding critical speeds. A rotor operating at a speed below the first critical speed is called a rigid rotor, while one operating above the first critical speed is called a flexible rotor.
[0003] During use, the motor rotor is usually driven by electricity to rotate. When the motor drives the rotor to rotate, the rotor is gear-shaped and is made of solid plastic. Although this can improve the stability of the rotor during operation, the solid structure will increase the burden and resistance during the rotor rotation, thereby reducing the operating efficiency of the motor.
[0004] To this end, we designed a motor rotor and a motor. Utility Model Content

[0016] 1. The utility model provides the second through hole and the third through hole, so that after the swivel receives the electric drive signal from the motor, the rotation efficiency at the wind-breaking angle can be effectively improved during the rotation process, further reducing the resistance and burden existing in the prior art.

[0023] Reference Figures 1-4 A motor rotor includes a rotor 1. The rotor 1 is a rotor component existing inside the motor in the prior art. It is driven by electricity to rotate, thereby generating a driving force. The windbreak angles 2 are triangular in shape as a whole and are evenly arranged on the outer wall of the rotor 1. When the rotor rotates too long, the overall rotation efficiency can be improved. The first through-hole 3 is opened on the side wall of the windbreak angle 2 and is in a through-shape as a whole, which is used to improve the air circulation effect and reduce the wind resistance when the rotor 1 rotates too long.
[0024] The swivel 1 is provided with a plurality of second through holes 4 for improving air flow.

The third through holes 5 are rectangular as a whole, which can improve the circulation efficiency of the second through holes 4.
[0025] Extension shafts 7 for improving rotation efficiency are symmetrically provided in the swivel 1. The extension shaft 7 is an extension structure of the central shaft 6, which is used to increase the transmission range to improve the overall operating efficiency of the motor. The swivel 1 is provided with a central shaft 6 for connecting the motor. The central shaft 6 is the structure of the middle section of the rotor in the prior art, which is used to receive electric drive to rotate it. The extension shaft 7 is fixedly connected to the central shaft 6 through fasteners. The fasteners are auxiliary connecting components in the prior art. While effectively improving the connection strength, they also facilitate the later disassembly of the two. A hole is opened in the extension shaft 7, and an auxiliary shaft 8 for improving stability is provided in the hole. The auxiliary shaft 8 is used to improve the overall stability and avoid deviation under the influence of centrifugal force.
[0026] The extension shaft 7 is provided with a plurality of first connecting plates 9 for reducing wind resistance. The first connecting plates 9 are arranged on the side wall of the extension shaft 7, and there are six first connecting plates 9 as a whole, which are used to improve the rotation efficiency and support strength inside the swivel 1. The first connecting plate 9 is fixedly connected to the extension shaft 7 by welding. Welding is an existing connection technology. The two are welded by a welding machine and a welding rod, which can effectively improve the connection strength and service life of the two. The extension shaft 7 is symmetrically provided with a second connecting plate 10, and the second connecting plate 10 is provided with a through hole for improving air penetration. The second connecting plate 10 is hollowed out on the basis of the first connecting plate 9, so that the two second connecting plates 10 are in a hollow state, which is convenient for wind resistance pressure relief when the first connecting plate 9 rotates.
[0027] A plurality of connecting rods 11 are provided on the first connecting plate 9 and the second connecting plate 10. The connecting rods 11 are used to improve the wind-breaking effect of the first connecting plate 9 and the second connecting plate 10, and one end of the connecting rod 11 is fixedly connected to the first connecting plate 9 by welding. Welding is an existing connection technology. The two are welded by a welding machine and a welding rod, which can effectively improve the connection strength and service life of the two. One end of the connecting rod 11 is fixedly connected to the second connecting plate 10 by welding. Welding is an existing connection technology. The two are welded by a welding machine and a welding rod, which can effectively improve the connection strength and service life of the two.
[0028] One end of the extension shaft 7 is provided with a plurality of buffer springs 13 for absorbing impact. The buffer spring 13 is a buffer structure in the prior art, which has a telescopic effect to reduce the impact of the impact. A plurality of long grooves 12 are opened on the extension shaft 7. The long grooves 12 are grooves for accommodating the buffer springs 13. The two ends of the buffer spring 13 are fixedly connected to the inner wall of the long groove 12 by welding.
[0029] A motor is an electric drive device for driving a rotor in the prior art, and the entire motor needs to be driven by an external power supply.
[0030] The working principle of this utility model is as follows:
[0031] Before you start using the motor, you need to make sure that all components are correctly installed. Check that all components are intact and that the connections between them are firm and reliable, and use electricity to drive the central axis 6 to rotate it. The central axis 6, as the structure of the middle section of the rotor in the prior art, is responsible for receiving electricity and converting it into mechanical energy, thereby driving the entire rotor system to rotate. At this time, the design of the windbreak angle 2 helps to improve the overall rotation efficiency while reducing wind resistance. During the operation of the motor, the performance can be further optimized by adjusting the air circulation on the first connecting plate 9 and the second connecting plate 10. For example, the number and position of the connecting rods 11 can be adjusted to reduce wind resistance, or the position of the auxiliary shaft 8 can be changed to enhance stability.
