Description

Technical Field

[0001] The utility model relates to the technical field of motor design and manufacturing, in particular to a motor rotor mechanism equipped with a balancing block. Background Art

[0002] The motor is used in a special environment. The operation of the motor is an energy conversion function, which converts electrical energy into mechanical energy or mechanical energy into electrical energy. In the process of transmitting mechanical energy, the rotor rotates and outputs it to the shaft. The rotor will be eccentric during the manufacturing process, so that the rotor cannot rotate around the axis when rotating. From the outer surface of the rotor, the rotation trajectory is not circular, but elliptical. This is caused by the eccentricity of the rotor. Now it is necessary to design a balance block to be installed on the rotor, so that the eccentric part of the rotor can be counterweighted, so that the rotor rotates according to a circular trajectory. It is important that the balance block cannot fall off during high-speed rotation, otherwise it will damage the motor. Therefore, a balance block with a self-locking function should be designed. Summary of the invention

[0003] The utility model aims to provide a motor rotor mechanism equipped with a balancing block, wherein the balancing block has a self-locking function.

[0004] A motor rotor mechanism equipped with a balancing block comprises a copper bar rotor body, a motor shaft, a balancing frame and a self-locking balancing block. The copper bar rotor body is equipped with the motor shaft, two balancing frames are respectively equipped on the motor shaft and located at both ends of the copper bar rotor body, and each balancing frame is equipped with a self-locking balancing block.

[0005] Preferably, the balancing frame is a convex structure, a shaft mounting hole is provided at the center of the balancing frame, a plurality of self-locking balancing block mounting holes are provided at the edge of the balancing frame, and the self-locking balancing block mounting holes are arranged in a circle.

[0006] Preferably, the self-locking balancing block includes a plurality of protrusions, a connecting portion and a tightening portion, wherein the plurality of protrusions are connected to the connecting portion and the tightening portion, the plurality of protrusions are arranged in a circle, a groove is provided at the top of the tightening portion, and the connecting portion is mounted in the mounting hole of the self-locking balancing block.

[0007] The self-locking balancing block of the utility model needs to be quenched to increase the hardness of the self-locking balancing block, and the tightening craftsman is inserted into the top groove of the tightening part to tighten the self-locking balancing block on the balancing frame. The hardness of the protrusion of the self-locking balancing block is higher than the hardness of the plane of the balancing frame, which destroys the plane of the balancing frame, causing obstruction of the plane of the balancing frame, and generating protrusions and concave points, thereby locking the self-locking balancing block.

[0008] Small motors have cast aluminum rotors with balance columns on the rotor circumference for easy weight balance, while large motors have copper bar rotors without balance columns, making it difficult to balance the rotor circumference. The self-locking balance block designed in the utility model is installed in conjunction with the balance frame on both sides of the copper bar rotor body, which effectively ensures that the rotor rotation trajectory is circular.

[0009] The self-locking balancing block required for dynamic balancing can be installed on the copper bar rotor body, and the rotor will not rotate with unbalanced weight. During the high-speed rotation of the rotor, the self-locking balancing block will not fall off due to its self-locking function. In this way, the utility model can effectively prevent the eccentricity of the rotor rotating part and the falling of the balancing block, thereby reducing the number of motor damages.

DETAILED DESCRIPTION

[0016] In order to make the technical solution of the present utility model easier to understand, the technical solution of the present utility model is now clearly and completely described in the form of specific embodiments in combination with the accompanying drawings.

[0017] Please also see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The motor rotor mechanism equipped with a balancing block includes a copper bar rotor body 1, a motor shaft 2, a balancing frame 3 and a self-locking balancing block 4. The copper bar rotor body 1 is assembled with the motor shaft 2. Two balancing frames 3 are respectively assembled on the motor shaft 2 and are located at both ends of the copper bar rotor body 1. Each balancing frame 3 is equipped with a self-locking balancing block 4.

[0018] The balancing frame 3 is a convex structure, a shaft fitting hole 30 is provided at the center of the balancing frame, and a plurality of self-locking balancing weight mounting holes 31 are provided at the edge of the balancing frame. The self-locking balancing weight mounting holes 31 are arranged in a circle.

[0019] The self-locking balancing weight 4 includes a plurality of protrusions 40, a connecting portion 41 and a tightening portion 42. The plurality of protrusions 40 are connected to the connecting portion 41 and the tightening portion 42. The plurality of protrusions 40 are arranged in a circle. A groove 43 is provided at the top of the tightening portion 42. The connecting portion 41 is mounted in the self-locking balancing weight mounting hole 31.

[0020] The self-locking balancing weight 4 of the present invention needs to be quenched to increase the hardness of the self-locking balancing weight 4. The tightening craftsman inserts the tightening part into the top groove 43 of the tightening part 42, and tightens the self-locking balancing weight 4 on the balancing frame 3. The hardness of the protrusion 40 of the self-locking balancing weight 4 is higher than the hardness of the plane of the balancing frame 3, which destroys the plane of the balancing frame 3, causing obstruction on the plane of the balancing frame 3, and generating protrusions and concave points, thereby locking the self-locking balancing weight 4.

[0021] Small motors are cast aluminum rotors with balance columns on the rotor circumference for easy weight balance, while large motors are copper bar rotors without balance columns, making it difficult to balance the rotor circumference. The self-locking balance block 4 designed in the utility model is installed on both sides of the copper bar rotor body 1 in cooperation with the balance frame 3, which effectively ensures that the rotor rotation trajectory is circular.

[0022] The self-locking balancing block 4 is required for dynamic balancing. After the self-locking balancing block 4 is installed on the copper bar rotor body 1, the rotor rotates without eccentricity. During the high-speed rotation of the rotor, the self-locking balancing block 4 will not fall off due to its self-locking function. In this way, the utility model can effectively prevent the eccentricity of the rotor rotating part and the falling of the balancing block part, thereby reducing the number of motor damages.
