Description

Technical Field

[0001] The utility model relates to the technical field of motor rotors, in particular to a plum blossom-shaped rotor structure. Background Art

[0002] The rotor of the motor is usually a plum blossom-shaped structure, which is used for winding enameled wire, so that the rotor can generate a magnetic field, transfer energy and drive the load in the motor, thereby driving the device connected to the shaft rod of the rotor to rotate.

[0003] When the shaft of the existing plum blossom-shaped rotor with direct plug-in connection is used to transmit high-torque equipment, the friction between the shaft and the silicon steel sheet is insufficient, and it is easy to slip due to asynchronous rotation, which affects the stability and reliability of the motor. Therefore, a plum blossom-shaped rotor structure is proposed to provide the motor with a set of plum blossom-shaped rotor structures with good integration of steel sheets and shaft rods and high torsion resistance. After the rotor is working and generating rotational force, the torsional force between the shaft and the stacked silicon steel sheets is better. Utility Model Content

[0004] In response to the problems in the prior art, the utility model provides a plum blossom-shaped rotor structure to provide a motor with a set of steel sheets and shafts with good integrity and high torsional resistance. After the rotor is working and generating rotational force, the torsional force between the shaft and the stacked silicon steel sheets is better.

[0005] The technical solution adopted by the utility model to solve the technical problem is a plum blossom-shaped rotor structure, comprising:

[0006] Rotor seat;

[0007] A stacking portion, disposed on the rotor seat;

[0008] The shaft portion is connected to the stacking portion.

[0009] By adopting the above technical scheme, through the components consisting of the rotor seat, the stacking part and the shaft rod part, it is achieved to provide the motor with a set of plum blossom-shaped rotor structures with good integrity of steel sheets and shaft rods and high torsional resistance, which effectively avoids slipping between the shaft part and the stacked silicon steel sheet parts. After the rotor is working and generates rotational force, the torsional force between the shaft part and the stacked silicon steel sheet parts is better, so that the stability of the rotor is improved and the motor as a whole is more reliable.

[0010] Specifically, the shaft portion includes:

[0011] A rotating shaft is arranged on the stacking portion;

[0012] Anti-slip texture, set on the shaft;

[0013] At least one anti-falling structure is provided and arranged on the rotating shaft.

[0014] Specifically, the anti-falling structure includes:

[0015] A pin hole is provided on the rotating shaft;

[0016] A spring is arranged in the pin hole and connected to the rotating shaft;

[0017] The pin is arranged in the pin hole and connected with the spring.

[0018] By adopting the above technical solution, the anti-slip performance of the shaft can be improved.

[0019] Specifically, the stacking portion includes:

[0020] Plum blossom shaped silicon steel sheet;

[0021] The shaft hole is arranged at the center of the plum blossom-shaped silicon steel sheet;

[0022] At least one group of pin holes is provided and opened on the inner wall of the shaft hole.

[0023] Specifically, the diameter of the pin hole is consistent with the diameter of the pin column, the end face of the pin column is an inner chamfer, and the end face of the pin hole is an outer chamfer.

[0024] Specifically, the sum of the lengths of the pin and the spring is less than the depth of the pin hole, and the depth of the pin hole is less than the length of the pin.

[0025] By adopting the above technical solution, under the action of centrifugation, the pin column can be inserted between the pin hole and the column pin hole.

[0026] The beneficial effects of the utility model are as follows: through the components consisting of the rotor seat, the stacking part and the shaft rod part, a plum blossom-shaped rotor structure with good integration of steel sheets and shaft rods and high torsion resistance is provided for the motor, which effectively avoids slipping between the shaft part and the stacked silicon steel sheet part. After the rotor is working and generates rotational force, the torsional force between the shaft part and the stacked silicon steel sheet part is better, so that the stability of the rotor is improved and the motor as a whole is more reliable. The problem that the shaft of the existing plum blossom-shaped rotor with direct plug-in connection is not sufficiently frictional with the silicon steel sheet when transmitting large torque equipment is solved, and the phenomenon of slipping due to asynchronous rotation is prone to occur, which affects the stability and reliability of the motor.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] In order to improve the reliability of use, Figure 1-5 As shown, the utility model is a plum blossom-shaped rotor structure, comprising:

[0036] Rotor seat 1;

[0037] The stacking part 2 is arranged on the rotor seat 1, and the tail of the stacking part 2 is connected to the rotor seat 1 through a bearing;

[0038] The shaft portion 3 is connected to the stacking portion 2 .

[0039] When in use, the assembly consisting of the rotor seat 1, the stacking part 2 and the shaft rod part 3 is used to provide the motor with a set of plum blossom-shaped rotor structures with good integration of steel sheets and shaft rods and high torsional resistance, thereby improving the reliability of use.

[0040] To improve stability, for example, Figure 3 As shown, the utility model also includes that the shaft portion 3 includes:

[0041] The rotating shaft 301 is arranged on the stacking part 2;

[0042] Anti-slip pattern 302, provided on the rotating shaft 301;

[0043] At least one anti-falling structure 303 is provided and is disposed on the rotating shaft 301 .

[0044] When in use, the rotating shaft 301 with the anti-drop structure 303 and the anti-skid pattern 302 is inserted into the stacking part 2. The anti-skid pattern 302 and the anti-drop structure 303 increase the friction between the rotating shaft 301 and the stacking part 2, thereby improving the stability in use.

[0045] For example, Figure 3 , 4 As shown, the utility model also includes that the anti-falling structure 303 includes:

[0046] A pin hole 3031 is provided on the rotating shaft 301;

[0047] The spring 3032 is disposed in the pin hole 3031 and connected to the rotating shaft 301;

[0048] The pin 3033 is disposed in the pin hole 3031 and connected to the spring 3032 .

[0049] When in use, the pin 3033 is pulled into the pin hole 3031 of the rotating shaft 301 by the spring 3032, and an elastically retractable and displaceable structure is formed between the pin 3033 and the rotating shaft 301. In the non-rotating state, the pin 3033 is retracted in the pin hole 3031 and will not affect the assembly of the rotating shaft 301 to the stacking part 2.

[0050] For example, Figure 5 As shown, the utility model also includes that the stacking portion 2 includes:

[0051] Plum blossom shaped silicon steel sheet 201;

[0052] The shaft hole 202 is arranged at the center of the plum blossom-shaped silicon steel sheet 201, and the rotating shaft 301 is inserted into the shaft hole 202, and the shaft hole 202 and the rotating shaft 301 are interference fit;

[0053] At least one group of pin holes 203 is provided and opened on the inner wall of the shaft hole 202 .

[0054] When in use, when the rotor of the present application is in a rotating state, the end of the pin 3033 will be thrown out of the pin hole 3031 due to the centrifugal force and enter the pin hole 203, so that the torsion resistance between the stacking part 2 and the shaft part 3 is better, and the rotating shaft 301 can better drive the connected equipment to rotate, with good stability and high reliability.

[0055] The diameter of the pin hole 203 is consistent with the diameter of the pin column 3033, the end face of the pin column 3033 is an inner chamfer, and the end face of the pin hole 203 is an outer chamfer. The sum of the lengths of the pin column 3033 and the spring 3032 is less than the depth of the pin hole 3031, and the depth of the pin hole 203 is less than the length of the pin column 3033.

[0056] When the utility model is in use, the plum blossom-shaped rotor of the present application is inserted into the stator housing of the motor, and the rotor seat 1 is riveted to the housing, and then the shaft 301 is connected and fixed to the equipment to be driven. After power is turned on, the shaft 301 of the rotor of the present application will provide driving force for the equipment. Based on the anti-slip pattern 302 and the anti-falling structure 303, the friction between the shaft 301 and the stacking part 2 is improved, and the stability of use is improved. The pin 3033 is pulled into the pin hole 3031 of the shaft 301 by the spring 3032, and an elastic and retractable displacement structure is formed between the pin 3033 and the shaft 301. During operation, after the rotation force is generated, the pin 3033 is acted on by the centrifugal force, and the end of the pin 3033 will be thrown out of the pin hole 3031 and enter the pin hole 203, so that the torsion resistance between the stacking part 2 and the shaft part 3 is better, so that the shaft 301 can better drive the connected equipment to rotate, with good stability and high reliability.
