Description

Technical Field

[0001] The utility model belongs to the technical field of wind energy motors, and in particular relates to a rotor base of a wind energy motor. Background Art

[0002] The rotor frame is connected to the bearing on the main shaft through the bearing sleeve on it. The rotor frame is also used to support and fix the permanent magnet poles. The rotor frame serves as the rotor frame of the wind turbine to support and stabilize the rotor poles. The rotor frame of traditional technology usually adopts a simpler structural design, which may be composed of several support beams or support rods to connect the bearings on the main shaft and other components of the rotor. This rotor frame design is relatively simple and low cost;

[0003] The stability of the rotor frame may be affected due to the simple design of the support structure. Simple support structures are difficult to provide adequate support and fixation, so vibration and noise problems are prone to occur during high-speed operation. Vibration and noise will affect the balance and axial stability of the rotor, resulting in reduced operating efficiency of the rotor. This type of rotor frame may not be structurally strong enough to withstand greater torque and pressure. The support beams or support rods used for connection and support may not be sufficiently reinforced and optimized in design, so they cannot provide sufficient structural strength. This may cause the rotor frame to deform or even be damaged when operating at high loads and high power, reducing the load-bearing capacity and vibration resistance of the rotor frame.

[0018] Compared with the prior art, the technical effects and advantages of the utility model are as follows: the front and rear ends of the bearing sleeve of the wind power generator rotor base are respectively connected to the mounting ring through two sets of support members, which enhances the stability of the rotor, can effectively reduce vibration and noise, and improve the operating efficiency of the rotor.

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.

[0028] The following is combined with Figure 1-5 To further explain this application in detail,

[0029] The embodiment of the present application discloses a wind power generator rotor base, comprising a bearing sleeve 1 connected to a bearing on a main shaft, wherein the front and rear ends of the bearing sleeve 1 are respectively connected to a mounting ring 3 through two sets of support members 2, and a yoke 4 is fixedly disposed on the outer side of the mounting ring 3;

[0030] The support member 2 includes a plurality of I-shaped support rods 21 which are arranged in a ring shape with equal distances and whose two ends are respectively limitedly inserted into the bearing sleeve 1 and the mounting ring 3, and an annular plate 22 connecting the plurality of I-shaped support rods 21. A reinforcing rod 23 is provided between two adjacent I-shaped support rods 21. The I-shaped support rod 21 and the reinforcing rod 23, the bearing sleeve 1 and the mounting ring 3 are formed into a whole by full penetration groove welding.

[0031] The front and rear ends of the bearing sleeve 1 are connected to the mounting ring 3 through two groups of support members 2, respectively, which enhances the stability of the rotor, can effectively reduce vibration and noise, and improve the operating efficiency of the rotor. The support members 2 include I-shaped support rods 21 arranged in a ring with equal distances. The outer sides of these support rods are fixed with yokes 4, which can support and fix the permanent magnet poles to ensure the stability of the position of the poles on the rotor, which is conducive to generating a stable magnetic field. Full penetration groove welding is adopted between the I-shaped support rods 21 and the reinforcing rods 23, the bearing sleeve 1, and the mounting ring 3 to form a whole, which enhances the structural strength of the rotor and can withstand greater torque and pressure.

[0032] The annular plate 22 is threadedly connected to the I-shaped support rod 21 through bolts 6 , and the annular plate 22 is located at the bottom of the reinforcing rod 23 , and the annular plate 22 and the reinforcing rod 23 are welded.

[0033] The annular plate 22 and the reinforcing rod 23 are welded together, which can enhance the stability of the entire supporting structure, improve the bearing capacity and vibration resistance of the rotor, and at the same time, through the connection method of bolts 6, this design is conducive to manufacturing and installation, which can improve production efficiency and reduce manufacturing costs.

[0034] The bearing sleeve 1 is provided with closing grooves A7 arranged at equal intervals in an annular pattern for limiting and inserting with the I-shaped support rod 21, and the mounting ring 3 is provided with closing grooves B8 arranged at equal intervals in an annular pattern for limiting and inserting with the I-shaped support rod 21;

[0035] The closing groove A7 is closed from the bearing sleeve 1 toward the direction of the I-shaped support rod 21 , and the closing groove B8 is closed from the mounting ring 3 toward the direction of the I-shaped support rod 21 .

[0036] The design of the closing groove can improve the connection accuracy between the bearing sleeve 1 and the mounting ring 3 and the I-shaped support rod 21. Through the limited insertion of the closing groove, it can ensure that the I-shaped support rod 21 is installed in the correct position, reducing the structural instability and performance degradation caused by installation errors. The design of the closing groove makes the connection between the bearing sleeve 1 and the mounting ring 3 and the I-shaped support rod 21 more firm, thereby improving the stability of the entire rotor base. This structural design can effectively bear the weight of the rotor and the magnetic poles, and resist the vibration and impact caused by the rotation of the rotor.

[0037] The design of the closing groove helps to simplify the installation process. Due to the limiting effect of the groove, the I-shaped support rod 21 can be quickly and accurately positioned during installation, which improves the installation efficiency and reduces the possibility of manual operation errors. The structure of the closing groove can improve the durability of the entire rotor base. By closing the bearing sleeve 1 and the mounting ring 3, the fatigue resistance of these components can be enhanced and the service life of the motor can be extended.

[0038] The welding point between the I-shaped support rod 21 and the bearing sleeve 1 is a full penetration groove weld A9, and the welding point between the I-shaped support rod 21 and the mounting ring 3 is a full penetration groove weld B10.

[0039] The welding point between the reinforcing rod 23 and the I-shaped support rod 21 is a full penetration groove weld C11.

[0040] Full penetration groove welding is a high-strength welding method that ensures full penetration of the weld, thereby improving the strength of the weld. This can enhance the stability and load-bearing capacity of the rotor base. The full penetration groove welding method can improve the stability of the weld and reduce the loosening and deformation of the weld. This can reduce the vibration and noise of the rotor base and improve its operational stability and efficiency. The full penetration groove welding method can ensure uniform load distribution of the weld and reduce stress concentration at the weld, thereby improving the durability and life of the rotor base. The welded joints of the full penetration groove welding are easier to repair and replace, and the weld can be repaired or replaced when necessary. This can improve the maintainability and reliability of the rotor base.

[0041] The magnetic yoke 4 is provided with T-shaped slots 5 arranged in an annular manner and at equal intervals, and are plugged and positioned to match the tenons on the magnetic poles.

[0042] The T-slot 5 cooperates with the tenon on the pole to achieve precise positioning. This can ensure the correct alignment between the pole and the yoke 4, maintain a stable magnetic field distribution and working effect, and by using the plug-in positioning of the T-slot 5, the installation of the pole becomes simpler and more convenient. The staff only needs to insert the tenon of the pole into the corresponding T-slot 5 for positioning, and the pole can be accurately positioned without the need for additional complicated steps. The design of the T-slot 5 can enhance the connection stability between the pole and the yoke 4. Through the tenon plug-in positioning, the shaking and displacement of the pole during operation can be reduced, and the stable magnetic force output and work efficiency can be maintained. The use of the T-slot 5 plug-in positioning can facilitate the maintenance and replacement of the pole. When the pole needs to be repaired or replaced, it is only necessary to release the plug-in positioning to easily disassemble and replace the pole, thereby improving the convenience of maintenance.

[0043] The rotor base of the wind power generator is connected to the main shaft through the bearing sleeve 1, and the front and rear ends of the bearing sleeve 1 are respectively connected to the mounting ring 3 through two sets of support members 2, which enhances the stability of the rotor. The yoke 4 is fixed to the outside of the mounting ring 3, and the support member 2 includes an I-shaped support rod 21, an annular plate 22, a reinforcing rod 23, etc. The I-shaped support rod 21 can support and fix the permanent magnet poles to ensure that the position of the poles on the rotor is stable, which is conducive to generating a stable magnetic field. The annular plate 22 is connected to the I-shaped support rod 21 by bolts 6, and the annular plate 22 is located at the bottom of the reinforcing rod 23, which enhances the stability of the entire support structure. The design of the closing groove helps to simplify the installation process. The staff only needs to insert the tenon of the pole into the corresponding T-slot 5 for positioning to accurately position the pole.

[0044] In summary, the wind power generator rotor frame is designed to enhance the stability of the rotor, the magnetic pole positioning accuracy and the magnetic field stability, while improving the durability, maintainability and reliability of the rotor frame, which helps to improve the performance and reliability of the wind power generator.
