Embodiment two: as shown in fig. 1 to 6, in a fan for testing a synchronous motor according to this embodiment, a screw hole is formed in a rotor bracket of the synchronous motor for mounting a fan base and a mounting base. The fan base is linked on the rotor support through bolts, and meanwhile, the installation seat is installed on the rotor support through bolts. Screw holes are arranged on the upper and lower sides of the notch of the fan base. The through holes of the fan adjusting blades are aligned with the threaded holes at the notch of the fan base. The first connecting bolt is inserted to enable the first connecting bolt to penetrate through the fan adjusting blade and the fan base.

Different mounting holes exist due to the mounting base itself. When the mounting angle is desired to be adjusted, the second connecting bolt on the mounting seat can be unscrewed. The second connecting bolt is re-screwed after aligning the connecting rod to the mounting hole of the desired angle. Thereby realizing the adjustment of the angle of the fan blade.
There are n flabellum on the unilateral on synchronous motor's the rotor support, there are 2n flabellums in bilateral symmetry, only illustrate the structural feature of a flabellum here. The qualitative requirements on the number and distribution of the fan blades are not made.
The patent is mainly used for the condition that the angle of the fan blade needs to be adjusted in the experimental process of the synchronous motor.
The synchronous motor is used for adjusting the angle of the fan blade, and is an effective technical means for controlling shaft channeling. In many cases, the fan blade angle needs to be adjusted to control axial movement. Simultaneously, the adjustment of the angle of the fan blade is also an effective technical means for controlling the cooling capacity of the synchronous motor cooling system.
In embodiment three: as shown in fig. 1 to 6, a fan for testing a synchronous motor according to this embodiment is described in brief as follows:
if the synchronous motor generates the shaft channeling phenomenon in the test process, the shaft channeling phenomenon needs to be improved by adjusting the angle of the fan blade. In the past, blades with different angles need to be manufactured again, and after the manufacture is completed, the fan blades on the original motor are detached, and new fan blades are replaced again. The worker is cumbersome to operate and has to wait for a complete manufacturing cycle of the blade each time the blade is made. And each test can only verify whether one angle improves the shaft channeling phenomenon. And sometimes require multiple changes, even 4 or 5 changes of angle. A great deal of time waste can be caused when the angle is changed every time, and the disassembly and the assembly are troublesome. The construction period is often seriously affected. And the fan blade with failed test results can cause stock waste.
The test fan of this application is in the use, is fixed the fan base on synchronous machine rotor support earlier, also fixes the mount pad on rotor support simultaneously, and the tap hole has all been bored in advance to the mounted position of fan base and the mounted position of mount pad on rotor support, has had the location in advance. After the fan base is fixed, fan adjusting blades are fixed on the side face of the fan base, one end of a connecting rod is fixed on a middle threaded hole of a connecting block on the fan adjusting blades, and the other end of the connecting rod is connected with a mounting seat fixed on the rotor support in advance through bolts. Wherein the connecting rod is correspondingly installed with the initial installation hole of the installation seat. Thereby ensuring the initial angle of the fan blade which is installed for the first time. The test fan is installed; one end of the connecting rod is connected with the adjusting fan blade, and the other end is connected with the mounting seat. The angle can be adjusted by adjusting the position of the mounting hole of the connecting rod on the mounting seat, which is close to one end of the mounting seat. When moving towards the mounting hole on one side close to the fan blade, the fan blade angle can be increased, and when moving towards the mounting hole on one side far away from the fan blade, the fan blade angle can be reduced. The angle of the fan adjusting blade can be changed by changing the installation position of the connecting rod.
According to the invention, the test steps are changed into the replacement of the fan under the condition that the shaft of the synchronous motor is in a channeling state. And (3) performing a test to measure shaft channeling, and if the shaft channeling is not improved, stopping the test to change the angle of the fan blade and increasing or decreasing the fixed angle. And (5) testing again. The test again measures shaft channeling, and the degree of shaft channeling is changed due to the change of the angle of the fan blade. The fan blade angle can be changed again through the rule. Thereby improving the shaft channeling condition. When the shaft channeling is improved, the conventional fan blade can be produced according to the angle for installation and replacement. The fan of the invention is continuously used for the next time of the shaft channeling test of the synchronous motor.
The test comparison of the two fans shows that the angle of the fan can be freely adjusted, and the time in the experimental process is greatly shortened. Omitting a whole manufacturing period for waiting for fan blade manufacture. And no waste is caused. The invention can complete the angle adjustment without frequently disassembling the fan blades, namely, the fan arranged on the rotor bracket is not required to be disassembled. The operation is convenient.
In the foregoing, the present invention is merely preferred embodiments, which are based on different implementations of the overall concept of the invention, and the protection scope of the invention is not limited thereto, and any changes or substitutions easily come within the technical scope of the present invention as those skilled in the art should not fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
