Description

Technical Field

[0001] The present invention relates to the technical field of motors, and in particular to a starting control device for a three-phase asynchronous motor. Background Art

[0002] A three-phase asynchronous motor is a type of induction motor. When current flows through the stator, part of the magnetic flux passes through the short-circuit ring, generating an induced current. The current in the short-circuit ring impedes the change in magnetic flux, causing a phase difference between the magnetic flux generated by the short-circuit ring and the flux generated by the non-short-circuit ring, thus forming a rotating magnetic field. After power is applied and started, the rotor windings induce an electromotive force and current due to the relative motion between the rotor windings and the magnetic field. This means that the rotating magnetic field and the rotor have a relative speed, and the interaction with the magnetic field generates electromagnetic torque, which rotates the rotor and achieves energy conversion. Three-phase asynchronous motors are widely used in industrial production and mechanical equipment due to their simple structure and reliable operation.

[0003] However, the existing three-phase asynchronous motor starting control device still has many problems. Traditional starting devices focus more on the electrical control part and pay insufficient attention to the coordinated optimization of the mechanical structure. As a result, during the starting process, the connection between the motor and the transmission mechanism is not stable enough, which is prone to vibration and impact, affecting the service life and operating accuracy of the equipment. In addition, as the motor is continuously used, the transmission coupling connected to the motor output shaft has the problem of wear and tear. After wear, gaps will be generated at its connection, which will intensify the vibration at the subsequent transmission. At the same time, the heat dissipation performance of the existing device is poor. When the current increases and the heat is intensified at the moment of motor starting, it cannot dissipate heat in a timely and effective manner, further reducing the reliability and stability of the equipment. In view of this, we propose a starting control device for a three-phase asynchronous motor. Summary of the Invention

The main bevel gear 27 is threadedly connected to the surface of the main screw 24 through the thread groove. By driving the rotation of the main bevel gear 27, the main screw 24 whose internal thread connection and linear limit are adjusted to move, thereby achieving the effect of position adjustment of the airbag rubber clamping wheel 26, and achieving the effect of adaptive clamping of the surfaces of couplings of different sizes and models; two sets of auxiliary clamping devices 3, two sets of auxiliary clamping devices 3 are symmetrically arranged at one end of the motor body 1; the adjusting device 4, the adjusting device 4 is arranged on the main connecting base 21; the cold cycle cooling device 5, the cold cycle cooling device 5 is arranged on the motor body 1. The coupling at the output shaft connection of the motor body 1 is clamped and fixed by a combination of a main power clamping device 2 and two sets of auxiliary clamping devices 3. Three sets of rollers are formed by the airbag rubber clamping wheel 26 and the internal structure of the two sets of auxiliary clamping devices 3. The roller positioning method is adopted to ensure the normal transmission operation of the coupling surface while achieving stable clamping, thereby avoiding the problem of unstable connection between the output shaft of the motor body 1 and the transmission mechanism due to factors such as loss, thereby avoiding vibration and impact. At the same time, the speed of the airbag rubber clamping wheel 26 is regulated according to the speed of the motor body 1, and then combined with the cold cycle cooling device 5 to achieve the effect of adaptive circulation supply of cold air flow, fully utilizing the transmission kinetic energy of the output shaft of the motor body 1, driving the cooling cycle to achieve the effect of uniform heat dissipation and cooling of the entire motor body 1.

[0036] In this embodiment, the airbag rubber clamping wheel 26 includes a central through shaft 261, both ends of which are rotatably connected to the inside of the main clamping seat 25, and a rubber wheel 262 is fixedly connected to the central through shaft 261. The surface of the rubber wheel 262 is fixedly connected to a plurality of elastic airbags 263 distributed in a circular array, and the plurality of elastic airbags 263 are respectively fixedly connected to the surface of the central through shaft 261 through the connecting seat 264. The airbag rubber clamping wheel 26 is used to position and clamp the coupling, and the airbag rubber clamping wheel 26 as a whole adopts the shape of a roller, which ensures the normal transmission of the coupling surface while achieving stable clamping. By setting up multiple elastic airbags 263, it is possible to achieve that when the rubber wheel 262 rotates, the properties of the multiple elastic airbags 263 continuously squeeze, release, rebound and replenish air to provide circulation power for the cold air flow in the cold cycle cooling device 5.

[0037] Furthermore, a plurality of connecting grooves corresponding to the number and position of the connecting seat 264 are provided on the central shaft 261. The two ends of the central shaft 261 are fixedly connected with a one-way air inlet pipe 265 and a one-way air outlet pipe 266 respectively. The surface of the main clamp seat 25 close to the one-way air inlet pipe 265 is fixedly connected with a protective mesh cover 251. The protective mesh cover 251 is used to filter the gas that is one-way supplied to the one-way air inlet pipe 265. A guide groove 252 is provided inside the side of the main clamp seat 25 close to the one-way air outlet pipe 266. The air flow path is: outside the main clamp seat 25, inside the one-way air inlet pipe 265, through the central shaft 261, and in the elastic air bag 263. After being squeezed, the air returns from the elastic air bag 263 to the central shaft 261, and is then discharged to the guide groove 252 through the one-way air outlet pipe 266.

[0038] Furthermore, the cold cycle cooling device 5 includes a starting chamber 51, which is fixedly mounted on the motor body 1, and a motor protection sleeve 52 is fixedly connected to the starting chamber 51. A cooling base 53 is fixedly connected to the inside of the starting chamber 51, and a semiconductor refrigerator 54 is fixedly mounted on one side of the cooling base 53. A plurality of diversion plates 55 are fixedly connected to the other side of the cooling base 53. The plurality of diversion plates 55 are respectively arranged in an array of a plurality of groups of two baffles, and the positions of the two baffles are staggered, thereby achieving the effect of increasing the gas flow path in the cooling base 53. The semiconductor refrigerator 54 fully cools the circulating air flow, and a connecting pipe 57 is fixedly connected to the cooling base 53. The connecting pipe 57 is fixedly connected to an inner tube 58 at one end away from the cooling base 53. The inner tube 58 passes through the main limit head 23 and is slidably connected inside the main screw 24. The inner tube 58 is connected to the interior of the guide groove 252 through the main screw 24. One side of the cooling base 53 is connected to the interior of the motor protection sleeve 52 through the hole groove 56. The other side of the motor protection sleeve 52 close to the cooling base 53 is fixedly connected to the exhaust seat 59. The interior of the motor protection sleeve 52 is provided with a circulation cavity. 2 sets are set on the motor body 1, and the flow path of the gas in the guide groove 252 is: the interior of the main screw 24, the internal through pipe 58, the connecting pipe 57, the cooling base 53, the cavity inside the motor protective sleeve seat 52, and finally discharged from the exhaust seat 59 to the interior of the motor protective sleeve seat 52. During the gas circulation, it passes through the cooling base 53 and is assisted by the semiconductor refrigerator 54 in the cooling base 53 to cool down. When the cooled cold air flow flows through the interior of the motor protective sleeve seat 52, the motor protective sleeve seat 52 is cooled. The motor protective sleeve seat 52 is close to the motor body 1, thereby transferring the temperature of the cold air flow to the motor body 1. The temperature transferability is utilized to achieve the effect of quickly cooling the motor body 1. At the same time, the kinetic energy of the output shaft of the motor body 1 is fully utilized, and the interior of the motor protective sleeve seat 52 is fixedly connected to the surface of the starting chamber 51. The rotational speed of the output shaft of the motor body 1, the rotational speed of the coupling, and the rotational speed of the airbag rubber clamping wheel 26 are proportional, and the rotational speed of the rubber wheel 262 positively affects the frequency of squeezing of the elastic airbag 263, and then affects the frequency and flow rate of the one-way airflow replenishment, so that when the power of the motor body 1 is greater and the heat accumulation is more serious, the airflow circulation and cooling rate is higher, thereby achieving the purpose of adaptively cooling the motor body 1 as a whole.

[0039] In addition, the adjusting device 4 includes an engaging bevel gear disc 41, one end of the engaging bevel gear disc 41 is rotatably connected to the inside of the main connecting base 21, and the other end of the engaging bevel gear disc 41 engages the main bevel gear 27 through bevel teeth. The surface of the engaging bevel gear disc 41 is clamped with a positioning gear seat 42 through teeth, and the positioning gear seat 42 is slidably connected to the main connecting base 21. The main bevel gear 27 is rotated by the rotation of the engaging bevel gear disc 41. When the main bevel gear 27 rotates, it drives the main screw 24 with its internal thread connection and linear limit to move. The main screw 24 drives the airbag rubber clamping wheel 26 as a whole to move toward the coupling through the main clamping seat 25. By adjusting the rotation angle of the engaging bevel gear disc 41, the position of the airbag rubber clamping wheel 26 is adjusted, and then the effect of adaptive clamping of the coupling surfaces of different sizes and models is achieved.

[0040] It is worth noting that the main connecting base 21 is respectively fixedly connected with a magnetic plate 1 211 and a magnetic plate 2 212. The interior of the positioning gear seat 42 is magnetically connected to the surface of the magnetic plate 1 211. By moving the positioning gear seat 42, the positioning gear seat 42 that was originally magnetically fixed to the magnetic plate 1 211 is transferred to the magnetic plate 2 212 for magnetic fixation. After the movement, the positioning gear seat 42 loses the clamping effect with the meshing bevel gear disc 41. At this time, the operator directly rotates the meshing bevel gear disc 41, thereby achieving the effect of facilitating the movement of the meshing bevel gear disc 41 while providing the effect of fixing the meshing bevel gear disc 41 with stability.

[0041] The cam 32 is connected to the drive shaft 31 of the second drive mechanism 32, and the cam 32, which is connected to the drive shaft 31, is fixedly connected to the drive shaft 31 of the second drive mechanism 32. At the same time, when one meshing bevel gear disc 41 is rotated, the main bevel gear 27 and the two auxiliary bevel gears 37 can be meshed at the same time, thereby achieving the effect of simultaneously adjusting the two stabilizing clamping wheels 36 and the one airbag rubber clamping wheel 26.

[0042] When the starting control device of the three-phase asynchronous motor of the present invention is in use, after the coupling of the transmission mechanism is installed on the output shaft of the motor body 1, the coupling at the connection is located between the two stabilizing clamping wheels 36 and the airbag rubber clamping wheel 26. By moving the positioning gear seat 42, the positioning gear seat 42 that was originally magnetically fixed to the magnetic plate 1 211 is transferred to the magnetic plate 2 212 for magnetic fixation. After the movement, the positioning gear seat 42 loses the clamping effect with the meshing bevel gear disk 41. At this time, the operator directly rotates the meshing bevel gear disk 41. The rotation of the meshing bevel gear disk 41 simultaneously meshes the main bevel gear 27 and the two auxiliary bevel gears 37. When the main bevel gear 27 rotates, it drives the main screw 24 with its internal thread connection and linear limit to move. The main screw 24 drives the airbag rubber clamping wheel 26 to move as a whole toward the coupling through the main clamping seat 25, and the corresponding two stable clamping wheels 36 also move toward the coupling synchronously. By adjusting the rotation angle of the meshing bevel gear disk 41, the position adjustment of the airbag rubber clamping wheel 26 and the two stable clamping wheels 36 is achieved, thereby achieving the effect of adaptive clamping of coupling surfaces of different sizes and models. At the same time, the airbag rubber clamping wheel 26 and the two stable clamping wheels 36 are distributed on the coupling surface in the form of three rollers, which not only achieves the effect of clamping and positioning, but also achieves the purpose of ensuring the normal transmission operation of the coupling surface, thereby avoiding the problem of unstable connection between the output shaft of the motor body 1 and the transmission mechanism due to factors such as loss, thereby generating vibration and impact.When the motor body 1 is working, the semiconductor refrigerator 54 is started synchronously, and the semiconductor refrigerator 54 cools the gas inside the cooling base 53. At the same time, since the rubber wheel 262 in the airbag rubber clamping wheel 26 is affected by the rotation of the coupling during the period of clamping and positioning the coupling, the rubber wheel 262 drives the multiple elastic airbags 263 thereon to squeeze the coupling in turn during the rotation, and the gas in the multiple elastic airbags 263 is continuously squeezed, released, and rebounded during the rotation. The elastic airbags 263 After being squeezed, the gas inside is discharged into the guide groove 252 in one direction through the one-way air outlet pipe 266. During rebound, the gas is replenished from the outer coupling of the main clamp seat 25 through the one-way air inlet pipe 265, thereby realizing the effect of automatic one-way gas replenishment. The overall flow path of the airflow is: outside the main clamp seat 25, inside the one-way air inlet pipe 265, through the middle shaft 261, and in the elastic airbag 263. After being squeezed, the air returns from the elastic airbag 263 to the middle shaft 261, and is then discharged through the one-way air outlet pipe 266. Then, the air flows through the guide groove 252, the inner part of the main screw 24, and the inner part of the main screw 24. The gas flows through the inner tube 58, the connecting tube 57, the cooling base 53, the cavity inside the motor protection sleeve 52, and finally is discharged from the exhaust seat 59 to the interior of the motor protection sleeve 52. During the gas circulation, it passes through the cooling base 53 and is assisted by the semiconductor refrigerator 54 in the cooling base 53 to cool down. When the cooled cold air flow flows through the interior of the motor protection sleeve 52, the motor protection sleeve 52 is cooled. The motor protection sleeve 52 is close to the motor body 1, thereby transferring the temperature of the cold air flow to the motor body 1, and utilizing the temperature The transferability realizes the effect of quickly cooling the motor body 1. At the same time, the kinetic energy of the output shaft of the motor body 1 is fully utilized. The rotation speed of the output shaft of the motor body 1, the rotation speed of the coupling, and the rotation speed of the airbag rubber clamping wheel 26 are proportional, and the rotation speed of the rubber wheel 262 positively affects the frequency of squeezing of the elastic airbag 263, and then affects the frequency and flow rate of the one-way airflow supplement, so as to achieve the effect that when the power of the motor body 1 is greater and the heat accumulation is more serious, the airflow circulation and cooling rate is higher, thereby achieving the purpose of adaptive cooling of the motor body 1 as a whole.
