Description

Technical Field

[0001] The invention relates to the technical field of permanent magnet speed regulators, in particular to an internal circulation oil-cooled high-power permanent magnet speed regulator. Background Art

[0002] When the permanent magnet speed regulator is in continuous operation, the induced current in the conductor rotor will generate a lot of heat, which will reduce the efficiency of permanent magnet transmission on the one hand; on the other hand, it will increase the temperature of the permanent magnets in the permanent magnet rotor, resulting in irreversible demagnetization of the permanent magnets at high temperature. Therefore, in addition to optimizing the magnetic circuit structure of the permanent magnet speed regulator to reduce eddy current losses, the most direct way is to dissipate heat and cool down the inside of the permanent magnet speed regulator.

The cooling oil is continuously sprayed to the permanent magnet rotor 22 through the heat dissipation mechanism 5, and the oil carrying heat is recovered into the oil tank 1 in combination with the oil drain pipe 35.

[0033] like Figure 3 , Figure 4 As shown, the heat dissipation mechanism 5 includes heat sinks 52 uniformly arranged in the circumferential direction of the speed regulator housing 2, the heat sink 52 is hollow, and an oil distribution pipe 51 and an oil outlet pipe 53 are respectively provided at both ends of the heat sink 52, the oil distribution pipe 51 is connected to an annular pipe 50, the oil inlet pipe 34 is connected to the annular pipe 50, the annular pipe 50 is coaxially installed with the speed regulator housing 2, the oil distribution pipe 51 is connected to a spray pipe 55, the spray pipe 55 points to the permanent magnet rotor 22, and a follower component is connected between the conductor rotor 23 and the spray pipe 55.

[0034] Specifically, the oil inlet pipe 34 delivers the cooling oil into the annular pipe 50, and the cooling oil is dispersed into the heat sink 52 through the oil distribution pipe 51. After the cooling oil is radiated in the heat sink 52, it is sprayed on the surface of the permanent magnet rotor 22 through the oil distribution pipe 51 and the spray pipe 55, thereby cooling the permanent magnet rotor 22. The spray pipe 55 is distributed in an annular shape, thereby achieving continuous spray cooling of the permanent magnet rotor 22 at 360 degrees, thereby ensuring reliable cooling of the permanent magnet rotor 22.

[0035] Further, such as Figure 5 , Figure 6As shown, the follower assembly includes a clamping block 230 uniformly arranged on the outer periphery of the conductor rotor 23, a guide rail 57 is arranged on the side of the heat sink 52 close to the conductor rotor 23, a clamping block 2 58 is slidably installed on the guide rail 57, the clamping block 2 58 is connected to the annular frame 56, and matching grooves 560 are arranged on both sides of the annular frame 56.

[0036] Specifically, since the gap between the conductor rotor 23 and the permanent magnet rotor 22 will be adjusted as needed during operation, in order to ensure that the permanent magnet rotor 22 can be continuously sprayed and cooled when the conductor rotor 23 is adjusted, a guide rail 57 is provided on the heat sink 52, and the annular frame 56 is slidably installed between the second clamping block 58 and the guide rail 57, and the conductor rotor 23 is rotatably installed between the clamping block 1 230 and the annular frame 56. When the conductor rotor 23 adjusts the gap with the permanent magnet rotor 22, the conductor rotor 23 carries the annular frame 56 to move along the guide rail 57, and the spray pipe 55 on the annular frame 56 is adjustably connected to the oil outlet pipe 53 through the telescopic pipe 54, so as to realize continuous spray cooling before and after the gap adjustment.

[0037] Further, such as Figure 5 As shown, a partition plate 1 520 and a partition plate 2 521 are evenly spaced inside the heat sink 52 , a gap is set between the partition plate 1 520 and the outer end of the heat sink 52 , and the partition plate 2 521 is located on one side of the inner end of the heat sink 52 and has an oil hole 522 .

[0038] Specifically, in order to improve the cooling effect and reduce the oil temperature of the cooling oil, a partition plate 1 520 and a partition plate 2 521 are evenly arranged in the heat sink 52. After the cooling oil enters one end of the heat sink 52 through the oil distribution pipe 51, the cooling oil successively bypasses the upper end of the partition plate 1 520 and the oil hole 522 of the partition plate 2 521, thereby extending the travel distance and travel time of the cooling oil in the heat sink 52, thereby improving the heat dissipation effect of the cooling oil combined with the heat sink 52, further reducing the oil temperature sprayed on the permanent magnet rotor 22, and improving the cooling effect.

[0039] Further, such as Figure 7 , Figure 8As shown, the pitch adjustment mechanism 6 includes a fixing frame 7, the fixing frame 7 is fixedly connected to the oil tank 1, a transfer case 60 is arranged on the fixing frame 7, a driven gear 1 62 and a driven gear 2 63 are rotatably installed in the transfer case 60, the driven gear 1 62 and the driven gear 2 63 are coaxially installed, the driven gear 1 62 and the driven gear 2 63 are translationally installed, a central gear 61 is arranged on the input shaft 20, a threaded rod 68 is rotatably installed between the adjustment box 25 and the transfer case 60, and the threaded rod 68 is located in the transfer case 60.

[0040] Specifically, when it is necessary to adjust the distance between the conductor rotor 23 and the permanent magnet rotor 22, the driven gear 1 62 and the driven gear 2 63 are controlled to move, so that the driven gear 1 62 and the center gear 61 are meshed with each other, and the driven gear 2 63 and the driven gear 3 64 are meshed with each other, wherein the radius of the center gear 61 is smaller than that of the driven gear 1 62, and the radius of the driven gear 2 63 is smaller than that of the driven gear 3 64, so that the power reduction of the input shaft 20 is dispersed to the threaded rod 68, and the translation magnet frame 69 is controlled by the threaded rod 68 to move on the outside of the adjustment box 25, thereby driving the adsorption frame 232 and the matching sleeve 231 and the conductor rotor 23 to move along the axial direction, thereby adjusting the gap between the conductor rotor 23 and the permanent magnet rotor 22.

[0041] Further, such as Figure 7 As shown, the fixing frame 7 is provided with a mounting frame 70, the input shaft 20 passes through the mounting frame 70, a push-pull motor 67 is fixedly mounted on the mounting frame 70, a push-pull frame 65 is sleeved on the input shaft 20, the push-pull frame 65 is fixedly connected with the axis of the driven gear 1 62 and the driven gear 2 63, and a circular frame 71 is also provided on the fixing frame 7, the circular frame 71 is sleeved with the input shaft 20, and the central axis of the driven gear 1 62 and the driven gear 2 63 is connected with a telescopic rod 66. The driven gear 1 62, the driven gear 2 63, and the driven gear 3 64 are symmetrically arranged at the upper and lower ends of the transfer case 60, and the threaded rod 68 is symmetrically arranged at the upper and lower sides of the adjustment box 25.

[0042] Specifically, the push-pull motor 67 and the push-pull frame 65 are used to control the translation of the driven gear 1 62 and the driven gear 2 63 in the transfer case 60, thereby controlling the rotation of the threaded rod 68, and then driving the movement of the translation magnet frame 69. The driven gear 1 62, the driven gear 2 63, and the driven gear 3 64 are symmetrical, and the threaded rod 68 is also symmetrically arranged, so that the smooth movement of the translation magnet frame 69 can be achieved, and the stuck phenomenon of the translation magnet frame 69 caused by the unilateral driving force can be avoided.

[0043] Further, such as Fig. 9 As shown, the mating sleeve 231 is symmetrically provided with an adsorption frame 232, and the adsorption frame 232 is provided with a mating ball 233. A plurality of annular grooves 252 are continuously and evenly arranged on the outer side of the regulating box 25, and a through longitudinal slide groove 251 is provided between the annular grooves 252. The intersection of the longitudinal slide groove 251 and the annular groove 252 is provided with a smooth transition.

[0044] Specifically, by providing the longitudinal groove 251 and the annular groove 252 , the adsorption frame 232 can be stably confined in the annular groove 252 in combination with the matching ball 233 after the gap is adjusted, thereby avoiding unstable axial movement of the conductor rotor 23 and ensuring stable output of the output shaft 21 .

[0045] The working principle of the embodiment of the present invention is:

[0046] like Figure 1-Figure 9As shown, the oil inlet pipe 34 delivers the cooling oil into the annular pipe 50, and is dispersed into the heat sink 52 through the oil distribution pipe 51. After the cooling oil is radiated in the heat sink 52, it is sprayed on the surface of the permanent magnet rotor 22 through the oil distribution pipe 51 and the spray pipe 55, thereby cooling the permanent magnet rotor 22. The spray pipe 55 is distributed in an annular shape, so as to realize continuous spray cooling of the permanent magnet rotor 22 at 360 degrees, thereby ensuring reliable cooling of the permanent magnet rotor 22. Since the gap between the conductor rotor 23 and the permanent magnet rotor 22 will be adjusted as needed during operation, in order to ensure that the permanent magnet rotor 22 can be continuously sprayed and cooled when the conductor rotor 23 is adjusted, a guide rail 57 is provided on the heat sink 52, and the annular frame 56 is slidably installed between the second clamping block 58 and the guide rail 57, and the conductor rotor 23 is rotatably installed between the clamping block 1 230 and the annular frame 56. When the conductor rotor 23 adjusts the gap with the permanent magnet rotor 22, the conductor rotor 23 carries the annular frame 56 to move along the guide rail 57, and the spray pipe 55 on the annular frame 56 is adjustably connected to the oil outlet pipe 53 through the telescopic pipe 54, so as to realize continuous spray cooling before and after the gap adjustment. Partition plate 1 520 and partition plate 2 521 are evenly arranged in the heat sink 52. When the cooling oil enters one end of the heat sink 52 through the oil distribution pipe 51, the cooling oil bypasses the upper end of the partition plate 1 520 and the oil hole 522 of the partition plate 2 521 in turn, extending the travel distance and travel time of the cooling oil in the heat sink 52, thereby improving the heat dissipation effect of the cooling oil combined with the heat sink 52, further reducing the oil temperature sprayed on the permanent magnet rotor 22, and improving the cooling effect. When the distance between the conductor rotor 23 and the permanent magnet rotor 22 needs to be adjusted, the driven gear 1 62 and the driven gear 2 63 are controlled to move, so that the driven gear 1 62 and the central gear 61 are meshed with each other, and the driven gear 2 63 and the driven gear 3 64 are meshed with each other, wherein the radius of the central gear 61 is smaller than that of the driven gear 1 62, and the radius of the driven gear 2 63 is smaller than that of the driven gear 3 64, so that the power reduction of the input shaft 20 is dispersed to the threaded rod 68, and the translation magnet frame 69 is controlled by the threaded rod 68 to move outside the adjustment box 25, thereby driving the adsorption frame 232 and the matching sleeve 231 and the conductor rotor 23 to move along the axial direction, thereby adjusting the gap between the conductor rotor 23 and the permanent magnet rotor 22. By setting the longitudinal slide groove 251 and the annular groove 252, the adsorption frame 232 can be stably confined in the annular groove 252 in combination with the matching ball 233 after the gap is adjusted, so as to avoid the unstable axial movement of the conductor rotor 23, thereby ensuring the stable output of the output shaft 21.
