DETAILED DESCRIPTION
[0034] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.
[0035] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0036] Embodiment 1:
[0037] A self-cooling heat dissipation motor, such as Figure 1-Figure 8 As shown, it includes a casing 1 filled with lubricating cooling oil, an end cover 2 is fixed to the end face of the casing 1 by bolts, the inner wall of the end cover 2 is rotatably connected to the output shaft 3, a stator assembly 9 is fixed to the inner wall of the casing 1, and the inner wall of the casing 1 located on the inner side of the stator assembly 9 is rotatably connected to a rotor assembly 14 that cooperates with the stator assembly 9 through a rotor shaft 15, and the rotor shaft 15 is transmitted and matched with the output shaft 3 through a protective transmission mechanism 16.
[0038] The outer wall of the rotor shaft 15 is fixed with a shaft sleeve 12 by bolts, and the outer wall of the shaft sleeve 12 is provided with blades 13, and the end face of the casing 1 located at the blades 13 is fixed and connected with multiple outlet pipes 11, and the other ends of the multiple outlet pipes 11 are connected to the same collecting / diverting box 10 fixed to the outer wall of the casing 1, and the other side of the collecting / diverting box 10 is connected to the filter 8 through the connecting pipe 5, and the other end of the filter 8 is connected to the collecting / diverting box 7 fixed to the outer wall of the casing 1 through the connecting pipe 5, and the other side of the collecting / diverting box 7 is fixed with multiple inlet pipes 6, and the other end of the inlet pipe 6 is fixed and connected to the outer wall of the casing 1.
[0039] A plurality of machine feet 4 are welded to the bottom of the housing 1 .
[0040] When the device is in use, when the stator assembly 9 is energized, it can use electromagnetic induction to drive the rotor assembly 14 to rotate, thereby driving the rotor shaft 15 to rotate. The rotor shaft 15 drives the output shaft 3 to rotate through the protective transmission mechanism 16, thereby performing work externally. When the rotor shaft 15 rotates, it can also drive the blades 13 to rotate, thereby guiding the lubricating cooling oil in the casing 1, so that the lubricating cooling oil flows into the outlet pipe 11, and then flows into the filter 8 through the collecting / diverting box 2 10 for filtration, and then flows into the interior of the casing 1 through the collecting / diverting box 1 7 and the inlet pipe 6. In the process of flowing out from the inside of the casing 1 and flowing into the inside of the casing 1, the lubricating cooling oil exchanges heat with the outside to achieve heat dissipation, thereby achieving heat dissipation in the casing 1.
[0041] The device is provided with blades 13 which are directly fixed to the rotor shaft 15, so that on the one hand, the heat dissipation process can be synchronized with the start and stop of the entire motor, simplifying the control logic; on the other hand, the higher the rotation speed of the rotor shaft 15 and the faster the heat generation, the higher the rotation speed of the blades 13, the faster the circulation speed of the lubricating cooling oil, and the better the heat dissipation efficiency, thereby achieving efficiency matching of heat generation and heat dissipation relative to the rotation speed.
[0042] In order to solve the exact matching problem; Figure 3 As shown, the blade 13 is rotatably connected to the sleeve 12 and the rotor shaft 15, and a cavity 18 is provided inside the rotor shaft 15. A piston 19 is slidably fitted on the inner wall of the cavity 18, and one side of the piston 19 is connected to a synchronization block 20 through a connecting shaft 17. A limit frame 22 is fixed to the side wall of the synchronization block 20, and an eccentric shaft 23 is movably limited on the inner wall of the limit frame 22, and the eccentric shaft 23 is fixed to the eccentric position of the blade 13.
[0043] The end surface of the synchronization block 20 is buckled with an elastic body 21 , and the other end of the elastic body 21 is buckled with the inner wall of the rotor shaft 15 .
[0044] When the internal temperature of the casing 1 is relatively low, the thermal expansion and contraction of the gas in the cavity 18 will also make the overall gas volume smaller, and negative pressure will be generated in the cavity 18, thereby sucking the piston 19 to drive the synchronous block 20 to move, so that the blade 13 is rotated through the limit frame 22 and the eccentric shaft 23. At this time, the inclination angle of the blade 13 is relatively small, and its guiding force on the lubricating and cooling oil is small. When the internal temperature of the casing 1 increases, the gas in the cavity 18 will expand, thereby reducing the negative pressure in the cavity 18, and the synchronous block 20 will move in the opposite direction under the pulling force of the elastic body 21, thereby increasing the inclination angle of the blade 13, increasing the guiding force on the lubricating and cooling oil, and increasing the flow rate of the lubricating and cooling oil.
[0045] The device is provided with rotatable blades 13, so as to ensure the heat preservation function of reducing the flow rate of the lubricating cooling oil at low temperature and at the same time increase the external output power ratio at relatively low temperature. At the same time, it can also increase the guiding effect of the blades 13 on the lubricating cooling oil when the temperature is high to ensure the heat dissipation efficiency. At the same time, by utilizing the thermal expansion and contraction characteristics of the gas, the entire process can be completely automatically controlled by relying on the temperature in the casing 1.
[0046] In order to solve the efficiency problem; Figure 5 As shown, a hollow arc blade 24 is welded to the outer wall of the rotor shaft 15 at the connection between the casing 1 and the inlet pipe 6 , and the inner cavity of the hollow arc blade 24 is connected to the cavity 18 .
[0047] By providing the hollow arc blades 24, the outer fluid can be directed inwards when rotating, thereby also playing the role of a mobile lubricating cooling oil circulation drive. At the same time, the hollow arc blades 24 are connected to the cavity 18, so that the contact area between the gas in the cavity 18 and the inflowing lubricating cooling oil can be increased, thereby increasing the sensitivity to temperature and ensuring the reliability of the function of automatically adjusting the lubricating cooling oil circulation speed according to the temperature.
[0048] To solve the filtering problem; Figure 6 As shown, the filter 8 includes an outer shell 25, a cage filter element 26 and a base 27, the top outer wall of the base 27 is fixed with a threaded boss 1 28 and a threaded boss 29, the outer shell 25 is connected to the outer side of the threaded boss 1 28 by a thread, and the cage filter element 26 is connected to the inner side of the threaded boss 29 by a thread, the cage filter element 26 is coaxially fixed to the outer shell 25, one of the connecting pipes 5 is connected to the axis of the base 27, and the other connecting pipe 5 is connected to the inner wall of the base 27 between the threaded boss 1 28 and the threaded boss 29.
[0049] After the lubricating and cooling oil is converged through the collecting / diverting box 2 10 , it flows into the outside of the cage filter element 26 from between the threaded boss 1 28 and the threaded boss 2 29 , and then enters the inside of the cage filter element 26 through the cage filter element 26 . This process can achieve filtration, and the filtered lubricating and cooling oil enters the collecting / diverting box 1 7 from another connecting pipe 5 .
[0050] The device is provided with a filter 8, which can filter the lubricating cooling oil, thereby preventing iron filings and sludge in the lubricating cooling oil from affecting the normal operation of the motor. At the same time, the filter 8 adopts a combined structure of a cage filter element 26, a cage filter element 26, and a base 27, thereby enabling the entire outer shell 25 and the cage filter element 26 to be quickly installed and disassembled.
[0051] To solve security issues; Figure 7 , 8As shown, the protective transmission mechanism 16 includes a transmission disc 1 31 and a transmission disc 2 32, and the transmission disc 2 32 is fixed to the outer wall of the output shaft 3 through a connecting frame 30. A connecting shaft 2 37 is fixed to the side wall at the axis of the transmission disc 1 31, and a key-shaped groove 34 is provided on the outer wall of the connecting shaft 2 37. A key-shaped protrusion 33 that is clearance-matched with the key-shaped groove 34 is welded to the inner wall of the rotor shaft 15. A plurality of grooves 39 are provided on the end face of the transmission disc 1 31, and an arc head protrusion 38 that is limit-matched with the plurality of grooves 39 is fixed to the end face of the transmission disc 2 32.
[0052] When the rotor shaft 15 rotates, it can drive the connecting shaft 2 37 to rotate through the cooperation between the key-shaped protrusion 33 and the key-shaped groove 34, thereby driving the transmission plate 1 31 to rotate, and then drive the transmission plate 2 32 to rotate through the arc head protrusion 38 and the groove 39, thereby driving the output shaft 3 to rotate outward through the connecting frame 30 to perform work.
[0053] A second piston 35 is fixed to the other end of the second connecting shaft 37 . The second piston 35 is movably fitted to the inner wall of the cavity 18 , and a second elastic body 36 is buckled on the side of the second piston 35 opposite to the key-shaped protrusion 33 .
[0054] Due to the negative pressure in the cavity 18, the piston 2 35 is subjected to negative pressure suction, and the transmission disc 1 31 and the transmission disc 2 32 are tightly fitted through the connecting shaft 2 37, so that the torque is transmitted by utilizing the cooperation between the arc head protrusion 38 and the groove 39. In the process of transmission, if the load of the output shaft 3 exceeds the maximum load or gets stuck, at this time, since the arc head protrusion 38 and the groove 39 are in an arc surface, the torque transmission will generate a component force along the axial direction, so that the transmission disc 1 31 overcomes the suction and moves, and the arc head protrusion 38 and the groove 39 are disengaged.
[0055] The device can provide an overload protection function for the motor by setting a protective transmission mechanism 16, and by setting the protective transmission mechanism 16 to be composed of components such as piston 2 35, transmission plate 1 31, arc head protrusion 38, groove 39, etc., so that the higher the temperature of the motor itself, the earlier the overload protection will intervene, thereby preventing the motor from being damaged by rapid temperature increase caused by rapid heat generation due to its own heat and stagnation.
[0056] When the present embodiment is in use, when the stator assembly 9 is energized, electromagnetic induction can be used to drive the rotor assembly 14 to rotate, thereby driving the rotor shaft 15 to rotate. The rotor shaft 15 drives the output shaft 3 to rotate through the protective transmission mechanism 16, thereby performing work externally. When the rotor shaft 15 rotates, it can also drive the blades 13 to rotate, thereby guiding the lubricating cooling oil in the casing 1, so that the lubricating cooling oil flows into the outlet pipe 11, and then flows into the filter 8 through the collecting / diverting box 10 for filtration, and then flows into the inside of the casing 1 through the collecting / diverting box 1 7 and the inlet pipe 6. In the process of flowing out from the inside of the casing 1 and flowing into the inside of the casing 1, the lubricating cooling oil exchanges heat with the outside to achieve heat dissipation, thereby achieving heat dissipation in the casing 1. The end face of the synchronization block 20 is buckled with an elastic body 21, and the other end of the elastic body 21 is buckled to the inner wall of the rotor shaft 15.
[0057] When the internal temperature of the casing 1 is relatively low, the thermal expansion and contraction of the gas in the cavity 18 will also make the overall gas volume smaller, and negative pressure will be generated in the cavity 18, thereby sucking the piston 19 to drive the synchronous block 20 to move, so that the blade 13 rotates through the limit frame 22 and the eccentric shaft 23, and at this time, the inclination angle of the blade 13 is relatively small, and its guiding force on the lubricating cooling oil is small. When the internal temperature of the casing 1 increases, the gas in the cavity 18 will expand, thereby reducing the negative pressure in the cavity 18, and the synchronous block 20 moves in the opposite direction under the pulling force of the elastic body 21, so that the inclination angle of the blade 13 increases. , the guiding force on the lubricating and cooling oil is increased, and the flow rate of the lubricating and cooling oil is increased. Due to the negative pressure in the inner cavity of the cavity 18, the piston 2 35 is subjected to negative pressure suction, and then the transmission disc 1 31 and the transmission disc 2 32 are tightly fitted through the connecting shaft 2 37, so that the torque is transmitted by the cooperation of the arc head protrusion 38 and the groove 39. In the process of transmission, if the load of the output shaft 3 exceeds the maximum load or gets stuck, at this time, since the cooperation of the arc head protrusion 38 and the groove 39 is an arc surface, the torque transmission will generate a component force along the axial direction, so that the transmission disc 1 31 overcomes the suction and moves, and the arc head protrusion 38 and the groove 39 are disengaged.
[0058] Embodiment 2:
[0059] A self-cooling heat dissipation motor, such as Figure 1-Figure 8 As shown, in order to solve the sensitivity problem; this embodiment makes the following improvements on the basis of embodiment 1: the inner cavity of the cavity 18 is filled with a mixed gas of nitrogen dioxide and nitrogen tetroxide, and the equation for its reversible reaction is .
[0060] Since the cavity 18 of the rotor shaft 15 is relatively small in volume, when the temperature changes, the force generated solely by the thermal expansion and contraction characteristics of the gas is small, and reliable driving and sensing may not be achieved. In the present embodiment, by flushing the interior of the cavity 18 with a mixed gas, by utilizing a reversible reaction and a combination of volume change and heat absorption and release, when the temperature rises, on the one hand, the mixed gas itself will undergo thermal expansion, and on the other hand, the chemical equilibrium of the mixed gas will also move toward the direction of generating nitrogen dioxide, so that the volume increases again, and vice versa.
[0061] The device sets a mixed gas of nitrogen dioxide and nitrogen tetroxide in the inner cavity of the cavity 18, so that when the temperature changes, on the one hand, it can use the heat contraction effect of the gas itself to achieve volume change, and on the other hand, it can also use the shift of chemical equilibrium to intensify the volume change. When the chemical equilibrium shifts, it can also absorb heat / cold, thereby playing a certain role in temperature compensation, increasing the sensitivity to temperature changes in the entire control process.
[0062] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
