Description

Technical Field

[0001] The utility model relates to the technical field related to motor rotors, and in particular to a rotor structure of a motor. Background Art

[0002] Working process of the powder suction gas mixer: centrifugal force is generated in the high-speed rotor, and the material is sucked from the upper and lower feeding areas of the working head (two-way suction) and the working chamber from the axial direction or from the bottom of the working head (one-way suction). The strong centrifugal force will throw the material from the radial direction into the narrow and precise gap between the stator and the rotor. At the same time, the material is initially dispersed and emulsified through centrifugal extrusion, impact and other forces.

[0003] At present, the rotor structure in the prior art powder suction gas mixer has the following disadvantages during use: the multiple external gear blocks installed on the rotor structure are an integrated structure with the rotor structure, which makes it impossible to disassemble or install the external gear blocks individually, so that when the external gear blocks need to be replaced later, they need to be replaced as a whole, thereby increasing the replacement cost. For this reason, we have designed a motor rotor structure to solve the above problems. Summary of the invention

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a rotor structure of a motor.

[0007] The disassembly and assembly component is installed between the outer gear block and the rotor body, and is used to realize the disassembly or installation of a single outer gear block.

[0008] Preferably, the cross-section of the outer tooth block is a C-shaped structure.

[0009] Preferably, the number of the outer tooth blocks is six, and the width of the outer tooth blocks is 10.5 mm to 10.65 mm.

[0010] Preferably, the disassembly and assembly assembly comprises an insert block with a convex cross-section, and the insert block is fixed to a side wall of the outer gear block that is attached to the outer surface of the rotor body.

[0011] Preferably, the insert block is movably inserted into a slot provided on the outer side of the rotor body, and the length of the insert block is equal to the length of one end of the outer gear block affixed to the outer surface of the rotor body.

[0012] Preferably, a T-shaped hole is provided on the outer side wall of the rotor body away from the outer gear block, the T-shaped hole is connected to the slot, a screw is connected to the inner thread of the T-shaped hole, and the insert block will be locked in the slot when the screw is tightened.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: in the present invention, the rotor structure can improve equipment reliability and process capability, and improve labor productivity, while also reducing operating labor intensity and improving the degree of equipment automation; secondly, by providing a disassembly and assembly component, it is not only convenient for assembling the rotor structure, but also convenient for disassembling and replacing a single outer gear block, thereby greatly reducing the overall replacement cost.

[0019] In order to make the technical means, creative features, objectives and effects of the utility model easy to understand, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments.

[0020] Example

[0021] The multiple outer gear blocks 3 installed on the rotor structure are integrated with the rotor structure, which makes it impossible to remove or install the outer gear blocks 3 individually. When the outer gear blocks 3 need to be replaced later, they need to be replaced as a whole, which increases the cost of replacement.

[0022] Reference Figure 1-4 , a rotor structure of a motor, comprising a rotor body 1, a mounting shaft hole 2 is opened at the center of the rotor body 1, and a plurality of outer gear blocks 3 arranged in a ring array are installed on the outer side of the rotor body 1;

[0023] The disassembly assembly is installed between the outer gear block 3 and the rotor body 1 , and is used to realize the disassembly or installation of a single outer gear block 3 .

[0024] In this embodiment, the cross section of the outer gear block 3 is a C-shaped structure.

[0025] In this embodiment, the number of the outer tooth blocks 3 is six, and the width of the outer tooth blocks 3 is 10.5 mm to 10.65 mm.

[0026] The best width of the outer tooth block 3 is 10.6 mm, which can better match the technical requirements for use in a powder suction type gas mixer.

[0027] In this embodiment, in order to facilitate the disassembly and assembly of a single external gear block 3 and reduce the cost of replacement, a disassembly and assembly component is provided, including an insert block 31 with a convex cross-section. The insert block 31 is fixedly connected to a side wall of the external gear block 3 that is attached to the outer surface of the rotor body 1. The insert block 31 is movably inserted into a slot provided on the outer side of the rotor body 1. The length of the insert block 31 is equal to the length of one end of the external gear block 3 that is attached to the outer surface of the rotor body 1. A T-hole 32 is provided on the outer side wall of the rotor body 1 away from the external gear block 3. The T-hole 32 is connected to the slot. A screw 33 is connected to the inner thread of the T-hole 32. After the screw 33 is tightened, the insert block 31 will be locked in the slot.

[0028] The length of the slot is equal to the length of the insert block 31 .

[0029] Working principle: When using the rotor structure of the motor, when a single damaged outer gear block 3 needs to be replaced, the rotor body 1 is disassembled from the powder suction gas mixer, and by loosening the screws 33 at the corresponding outer gear block 3 that needs to be replaced, the plug block 31 connected to the corresponding outer gear block 3 can be pulled out from the slot, thereby facilitating the replacement of the single outer gear block 3 and greatly reducing the cost of replacing the outer gear block 3.
