Description

Technical Field

[0001] This invention belongs to the field of motor technology, and particularly relates to a heat dissipation structure for a high-speed motor. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It utilizes a rotating magnetic field generated by energized coils (stator windings) that acts on a rotor (such as a squirrel-cage closed aluminum frame) to create magnetoelectric torque. Electric motors are classified into DC motors and AC motors based on the power source used. Most motors in power systems are AC motors, which can be synchronous or asynchronous (the stator magnetic field speed and rotor rotation speed are not synchronized). An electric motor mainly consists of a stator and a rotor. The direction of the force on a current-carrying conductor in a magnetic field depends on the direction of the current and the direction of the magnetic field lines. The working principle of an electric motor is that the magnetic field exerts a force on the current, causing the motor to rotate.

[0003] Existing motors, such as the one described in Chinese Utility Model Patent Publication No. CN219513914U, use a fan at the front end of the motor to dissipate heat. However, during use, due to the high speed of the motor, the cooling efficiency of a single fan often cannot keep up with the heat generation rate of the motor, resulting in overheating. Therefore, we have specially designed a high-speed motor cooling structure. Summary of the Invention

The locking bolt passes through the locking hole and abuts against the wall surface at the collapsed part of the main body.

[0009] In the above technical solution, the base further includes: A base is set on a fixed end face, and a connecting hole is formed on the base; Positioning protrusions are formed on the base body; The fixed end face that mates with the base has a positioning groove formed therein, and the positioning groove and the positioning protrusion mate to make the connecting hole and the fixing hole concentric.

[0010] Furthermore, the above technical solution also includes: The external shock absorption assembly includes a left shock absorber plate, a right shock absorber plate, and a compensation component.

The motor component 10 is connected to the rear heat dissipation component 4 and enters the mounting cavity 5, extending forward to cooperate with the front heat dissipation component 3. In use, the rear heat dissipation component 4 sends air into the mounting cavity 5, and the front heat dissipation component 3 draws the gas out of the mounting cavity 5, thereby enhancing the air circulation rate inside the housing 1 and enabling rapid heat dissipation of the motor component 10. Furthermore, both the front heat dissipation component 3 and the rear heat dissipation component 4 are connected to the motor component 10 and are driven synchronously during the operation of the motor component 10, thereby saving energy consumption.

[0021] Example 2:

[0022] This embodiment provides a heat dissipation structure for a high-speed motor, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0023] The front heat dissipation component 3 includes: The front end 31 is connected to the machine cover 1. The front end 31 has a first shaft hole 311 formed in the center, and a first flange 312 is formed on the outer side of the first shaft hole 311 facing the inside of the machine cover 1. A bearing is provided on the inner side of the first flange 312. A connecting end 313 is formed on the periphery of the front end 31, and a threaded hole is provided on the connecting end 313. The fan cover 32 is disposed on the outside of the front end seat 31 and fixed to the cover 1. The fan cover 32 and the front end seat 31 form a first heat dissipation cavity 7. The first fan assembly 33 is disposed in the first heat dissipation cavity 7 and is connected to the motor component 10.

A first bearing 6 is installed on the inner side of the first flange 312. The first bearing 6 is used to connect the motor component 10. Thus, the front end seat 31 will not rotate with the motor component 10 under the action of the first bearing 6. A plurality of first air passage holes 314 are formed on the front end seat 31. The first air passage holes 314 are connected to the mounting cavity 5. The fan cover 32 is connected to the outside of the front end seat 31, and a through groove is formed on the fan cover 32.

The first fan assembly 33 is set to the mode of extracting air from the mounting cavity 5, i.e., the output mode. In use, the motor component 10 drives the first fan assembly 33 to rotate, drawing air out of the casing 1 into the first heat dissipation cavity 7, and then escaping through the through slot of the fan shroud 32, thereby achieving the effect of heat dissipation.

[0025] Example 3:

[0026] This embodiment provides a heat dissipation structure for a high-speed motor, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0027] The rear heat dissipation component 4 includes: The rear end seat 41 is connected to the machine cover 1. A second shaft hole 411 is formed in the center of the rear end seat 41. A second flange 412 is formed on the outer side of the side port of the second shaft hole 411 facing the inside of the machine cover 1. A second bearing 8 is provided on the inner side of the second flange 412. The second bearing 8 cooperates with the motor component 10. A mounting groove 413 is formed on the outer side of the side port of the rear end seat 41. A limit groove 414 is formed on the inner side of the mounting groove 413. The flange cover plate 42 has one end connected to the mounting groove 413 and has a limiting protrusion 421 formed therein. The limiting protrusion 421 cooperates with the limiting groove 414 to fix the flange cover plate 42 to the rear end seat 41. The other end of the flange cover plate 42 is provided with a third shaft hole 422. A second heat dissipation cavity 9 is formed between the flange cover plate 42 and the rear end seat 41. The second fan assembly 43 is disposed in the second heat dissipation cavity 9 and is fixed to the motor component 10; The motor component 10 extends through the third shaft hole 422 into the second heat dissipation cavity 9 and is connected to the second fan assembly 43.

[0028] As can be seen from this embodiment, the rear heat dissipation assembly 4 includes a rear end base 41, a flange cover plate 42, and a second fan assembly 43; The rear end seat 41 is connected to the rear end of the housing 1, and a second shaft hole 411 is formed on the rear end seat 41. A second flange 412 is formed on the outer wall of the side of the second shaft hole 411 facing the housing 1. The second flange 412 extends into the housing 1, and a second bearing 8 is installed inside the second flange 412. The second bearing 8 is used to connect the motor component 10. Thus, the rear end seat 41 will not rotate with the motor component 10 under the action of the second bearing 8. A mounting groove 413 is formed on the wall of the rear end seat 41 facing away from the housing 1. A flange cover plate 42 and a second fan assembly 43 are installed in the mounting groove 413, and the side wall of the mounting groove 413 corresponds to the second fan assembly 43. The fan assembly 43 is provided with multiple second air passages for air circulation. Furthermore, a limiting groove 414 is formed on the outer wall of the mounting slot 413 port. The limiting groove 414 is used to cooperate with the flange cover plate 42 for fixation. A second air passage is formed on the groove wall of one side of the limiting groove 414. The second air passage connects to the mounting cavity 5 and is used for air intake. Furthermore, a retaining groove is also formed on the second flange 412. A shaft elastic retaining ring 152 is connected to the retaining groove. After the second bearing 8 is installed in the second flange 412, the shaft elastic retaining ring 152 is connected to the retaining groove and fixes the second bearing 8 in the second flange 412. The flange cover plate 42 is connected to the mounting groove 413 and seals the mounting groove 413 to form the second heat dissipation cavity 9 to protect the second fan device. The flange cover plate 42 is cylindrical and has a third shaft hole 422 formed on it. The third shaft hole 422 is larger than the size of the motor component 10 and serves to allow air to enter. The three shaft holes are used to allow the motor component 10 to pass through. A limiting protrusion 421 is formed on one end of the flange cover plate 42 connected to the mounting cavity 5. During installation, the flange cover plate 42 connects one end of the limiting protrusion 421 to the mounting groove 413 and makes the limiting protrusion 421 snap into the limiting groove 414 to achieve fixation. The second fan assembly 43 is installed in the second heat dissipation cavity 9 and connected to the motor component 10. During use, the second fan assembly 43 draws air into the second heat dissipation cavity 9 through the third shaft hole 422. The air then flows into the mounting cavity 5 through the second air passage. Furthermore, since the second air passage is not opposite to the second fan assembly 43, the air will first come into contact with the wall of the mounting groove 413 before flowing into the mounting cavity 5 during the flow process. This can reduce the amount of dust entering the mounting cavity 5 and affecting the operation of the motor component 10.

After the abutting frame is engaged with the flat end, the wind cover 32 is locked on the body 11. A locking hole is formed on the wall at the junction of the protruding cover bodies 321. A locking bolt 13 is connected to the locking hole. The locking bolt passes through the locking hole and abuts against the wall at the collapsed part of the body 11.

[0032] As can be seen from this embodiment, the housing 1 includes a body 11 and four protruding end faces 12. The body 11 has a cylindrical structure, and the four end faces 12 are respectively formed on the four quadrant points of the body 11. The overall cross-sectional shape of the housing 1 is a rectangle with missing corners. Multiple grooves are formed on the left and right corresponding surfaces of the four end faces 12. The grooves cut the end faces 12 to form a sheet-like structure. The end faces 12 with the sheet-like structure are set as heat dissipation end faces 121. The other two corresponding end faces 12 are flat but have multiple fixing blocks. Multiple fixing holes 1221 are used to connect the base 2 and the motor component 10. The heat dissipation end face 121 includes a plate structure comprising a connecting part, a mating part, and a heat dissipation part. The connecting part is relatively wide and has a countersunk hole, which is used to fix it to the mounting hole 315 on the front end seat 31.

The heat dissipation part is a vertical plate that is relatively narrow and flat, thus facilitating heat dissipation during use. The fan cover 32 has protruding parts corresponding to the heat dissipation end face 121 and the fixed end face 122. The protruding cover 321 has abutting frames corresponding to the four end faces 12. The abutting frames abut against the mating parts on the heat dissipation end face 121 and the fixed end face 122 respectively, so that the fan cover 32 can be snapped on the end face 12 and initially fixed to the body 11. Furthermore, the wall surface of the protruding cover 321 on the fan cover 32 has locking holes formed. Locking bolts 13 are provided in the locking holes. The locking bolts 13 connect to the locking holes and gradually abut against the wall surface of the body 11 between adjacent end faces 12.

One side wall of the elastic element 1431 is used to connect the left damping plate 141 and the right damping plate 142. The other side wall of the elastic element 1431 is formed with protrusions 1432 of different heights. The multiple protrusions 1432 have different heights. When in use, under the action of the left damping plate 141 and the right damping plate 142, the side wall of the elastic element 1431 with the protrusions 1432 abuts against the end faces 12 on both sides of the cover 1, and the higher of the protrusions 1432 abuts against the end face 12. When vibration occurs, it deforms due to the force, so that the other protrusions 1432 abut against the end face 12, thereby absorbing the vibration and reducing the vibration.

[0045] Example 8:

[0046] This embodiment provides a heat dissipation structure for a high-speed motor, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0047] The built-in shock absorption assembly 15 includes a wave spring sheet 151 and a shaft elastic retaining ring 152. The wave spring sheet 151 is disposed between the first bearing 6 and the first flange 312, and the shaft elastic retaining ring 152 is disposed on the mating surface between the motor component 10 and the rear end seat 41.

[0048] As can be seen from this embodiment, the built-in shock absorption assembly 15 includes a wave spring sheet 151 and a shaft elastic washer; The wave-shaped elastic sheet is installed on the inner wall of the first flange 312 and abuts against the inner side of the first bearing 6. After the first bearing 6 and the motor component 10 are engaged, the wave-shaped elastic sheet absorbs the vibration generated by the operation of the motor component 10 and releases it through its own synchronous vibration, thereby effectively reducing the vibration impact of the operation of the motor component 10 on the first bearing 6. The shaft elastic washer is installed on the inner wall of the second flange 412 and abuts against the inner side of the second bearing 8. The shaft elastic washer is made of rubber material and absorbs the vibration generated by the motor component 10 during operation through its own elastic force, thereby effectively reducing the vibration impact of the motor component 10 on the second bearing 8.

The dustproof plate 161 has fine holes and is disposed on the wall of the mounting groove 413. The dustproof plate 161 seals the second air passage. The dust suction cylinder 162 is movably disposed in the through hole 415 and extends into the second heat dissipation cavity 9, abutting the lower side of the limiting protrusion 421.

[0052] As can be seen from this embodiment, the dustproof component 16 includes a dustproof plate 161 and a dust suction cylinder 162. The dustproof plate 161 is installed on the wall of the mounting groove 413 outside the second air passage and seals the second air passage. The dust suction cylinder 162 is installed in the through hole 415. The dust suction cylinder 162 is made of dust-absorbing material and absorbs dust in the air. During use, after the second fan assembly 43 draws air into the second heat dissipation cavity 9, the air collides with the wall of the mounting groove 413 and is guided to the second air passage on the periphery of the mounting groove 413. At the same time, the dustproof plate 161 filters the air.
