Description

Technical Field

[0001] This invention belongs to the technical field of vertical motor equipment, specifically relating to an energy-saving vertical motor structure with bearing oil cooling. Background Technology

[0002] The energy-saving vertical motor structure with bearing oil cooling refers to a type of motor construction scheme designed for vertical installation conditions. It uses lubricating oil as the cooling medium for internal circulating cooling. Its core function is to solve the problem of concentrated and uneven heat dissipation caused by the coupling of gravity and radial force in vertical motors, resulting in concentrated frictional heat generation in the bearings. This structure typically consists of a main shaft system, upper and lower bearing assemblies, an internal oil chamber, and an external circulating cooling device. The lubricating oil is driven by an internal oil pump or an external power source to circulate forcibly between the bearing chamber and the cooler. The cooled oil carries away frictional heat through the bearing raceway and cage, then flows through the ends of the motor stator windings for auxiliary heat dissipation, and finally returns to a plate or tubular cooler for heat exchange with external water or air. Special consideration must be given to oil level control and leak-proof sealing of the vertical shaft to prevent insufficient oil in the upper bearing or excessive oil pressure in the lower bearing. This type of structure is widely used in the main drive motors of large water pumps, mine hoists, and rolling mills, offering significant advantages such as long bearing life, high power density, and adaptability to frequent start-stop cycles.

[0003] In existing vertical motors, the bearing cooling mechanism typically involves installing the bearing in an oil chamber with the oil level controlled at half to two-thirds of the height of the lowest rolling element. When the bearing rotates, the oil at the bottom is thrown up and splashes onto all parts that need lubrication. At the same time, the flowing oil carries away the heat from the raceway, thereby cooling the shaft. However, the oil in the oil chamber consumes the rotational force of the shaft, thus reducing the output efficiency of the motor and causing mechanical losses in the existing bearing cooling mechanism. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an energy-saving vertical motor structure with bearing oil cooling.

[0005] The technical solution adopted to solve the above technical problems is: an energy-saving vertical motor structure with bearing oil cooling, including a housing, with sealing shells fixedly connected to the center of both sides of the housing, and shaft seats fixedly connected to the top and bottom of the housing; The top of the housing is fixedly connected to an upper end cover, which is located outside the top bearing seat of the housing. The bottom of the housing is fixedly connected to a lower end cover, which is located outside the bottom bearing seat of the housing. The rotor is located at the center of the interior of the housing, and two circulation mechanisms are installed in the two sealed shells.

[0006] Furthermore, a support frame is fixedly connected to the bottom of the inner wall of the upper cover, and an oil pipe is fixedly installed on the top of the support frame.

[0007] With the above technical solution, when using this motor equipment, the operator can add cooling oil into the oil pipe. When the entire motor is running, the cooling oil can be transported to the corresponding bearing through two circulation mechanisms, thereby cooling the motor parts. Moreover, the cooling oil in the oil pipe is circulating, which can continuously cool the motor and greatly improve the service life of the motor.

[0008] Furthermore, the bearing seat has an oil chamber at its center, a plurality of mounting holes at its top, an annular groove at the bottom of the oil chamber inside the bearing seat, a nozzle fixedly mounted in each of the plurality of mounting holes, and a mounting tube fixedly connected between the tops of the plurality of nozzles.

[0009] Through the above technical solution, when the motor is driven, the cooling oil in the oil pipe is drawn out by the circulation mechanism and then transported to the installation pipe, thereby delivering it to multiple nozzles. The multiple nozzles spray the cooling oil onto the bearing body, achieving cooling and reducing the temperature of the bearing body. When the bearing body is continuously sprayed, the heated cooling oil falls onto the annular inclined groove and accumulates. At this time, it is drawn out by the circulation mechanism and transported back into the oil pipe, where the oil pipe cools and reduces the temperature, achieving recycling and continuous cooling of the bearing body. The cooling oil not only cools the bearing body, but also forms an extremely thin oil film between the bearing rolling elements and raceways, which greatly reduces frictional resistance, thereby increasing the shaft rotation speed and improving the working efficiency of the motor.

[0010] Furthermore, the oil chamber and the annular inclined groove form a sealed cavity.

[0011] Through the above technical solution, the cooling oil sprayed onto the bearing body first falls onto the annular inclined groove, which is the bottom of the entire sealed cavity. The sealed cavity has a sealing effect, preventing the cooling oil from leaking out. It can also be transported by the circulation mechanism to prevent it from accumulating in the sealed cavity and preventing the accumulated cooling oil from submerging the bearing body, thereby greatly reducing the consumption of its rotational power. The cooling oil is sprayed by multiple nozzles, which makes the cooling oil cover a wide area, thereby cooling the dead corners, while preventing the cooling oil from consuming the rotational power of the bearing body, greatly improving the performance of the motor.

[0012] Furthermore, a rotating shaft is fixedly connected to the center of the rotor, and bearing bodies are fixedly installed at the top and bottom of the outer wall of the rotating shaft. An iron core is fixedly connected to the inner wall of the housing, and the rotor is located at the inner center of the iron core.

[0013] With the above technical solution, when the motor is in use, after the motor is powered on, a magnetic field that rotates continuously in space will be generated inside the iron core. This rotating magnetic field will pass through the air gap and act on the rotor, causing the rotor to start to rotate from a stationary state, thereby driving the shaft to rotate. The bottom end of the shaft is the output end, thereby realizing the rotation of external equipment. The entire rotor is mounted between two bearing seats through two bearing bodies, and then installed in the housing.

[0014] Furthermore, the two bearing bodies are located in their respective oil chambers.

[0015] Through the above technical solution, the two oil chambers cool the corresponding bearing bodies respectively, and the two bearing bodies are cooled at the same time, thereby improving the cooling of the shaft and thus providing efficient heat dissipation for the motor.

[0016] Furthermore, a flange is fixedly connected to the bottom of the lower end cover.

[0017] With the above technical solution, the entire motor can be connected to external equipment via a flange, and then assembled and connected via multiple fixing bolt assemblies, thereby improving the stability of the connection.

[0018] Furthermore, a fan is fixedly installed inside the upper end cover, and the fan is located above the oil pipe.

[0019] With the above technical solution, when the shaft rotates, it drives the fan to rotate, which in turn blows air to cool the oil pipe. Since the top of the upper cover has heat dissipation holes, cold air from the outside is sent into the motor, which not only cools down multiple parts inside the motor, but also cools down the cold air in the oil pipe, thereby cooling down the heated cooling oil in the oil pipe. The cooled cooling oil can then continue to cool down the bearing body, achieving recycling and greatly improving the service life of the motor.

[0020] Furthermore, the circulation mechanism includes a first pump body fixedly connected to one of the sealed housings, a first connecting pipe fixedly connected between the first pump body and the oil pipe, a second connecting pipe fixedly connected between the first pump body and the mounting pipe, a second pump body fixedly installed in the other sealed housing, a third connecting pipe fixedly connected between the second pump body and the oil pipe, and a fourth connecting pipe fixedly connected between the second pump body and the bottom of the annular inclined groove.

[0021] The above technical solution involves spraying oil to cool the bearing body. First, the first pump is activated, drawing cooler oil from one end of the oil pipe through the first connecting pipe. This oil is then transported to the mounting pipe through the second connecting pipe, which in turn delivers the cooler oil to multiple nozzles. Finally, the oil is sprayed onto the bearing body to cool it. Cooler oil that falls onto the annular groove, where its temperature rises. Second, the second pump is activated, drawing cooler oil from the bottom of the annular groove through the fourth connecting pipe. This oil is then transported to the other end of the oil pipe through the third connecting pipe, thus returning the hotter cooler oil to the oil pipe. A fan then cools the oil, covering the entire oil pipe and allowing for continuous circulation of cooler oil within the pipe. This ensures the hotter cooler oil at the other end of the pipe continues to cool. After cooling, the oil flows to the other end under the action of the first pump, facilitating continued spraying of cooler oil onto the bearing body.

[0022] Furthermore, the cooling oil in the oil pipe flows through one end to the first pump body and the mounting pipe, and the cooling oil above the annular inclined groove flows through the fourth connecting pipe, the second pump body and the third connecting pipe to the other end of the oil pipe.

[0023] Through the above technical solution, the cooling oil in the oil pipe can spray and cool the bearing body under the action of the first pump body. After cooling, the cooling oil flows back to the oil pipe for further cooling under the action of the second pump body, realizing recycling and greatly improving the service life of the motor, while also greatly reducing the energy loss of the motor due to the cooling oil.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention designs two circulation mechanisms. The cooling oil in the oil pipe flows to the first pump body and the mounting pipe through one end of the pipe. The cooling oil above the annular groove flows to the other end of the oil pipe through the fourth connecting pipe, the second pump body and the third connecting pipe. This allows the cooling oil in the oil pipe to spray and cool the bearing body under the action of the first pump body. After cooling, the cooling oil flows back to the oil pipe to cool it under the action of the second pump body, realizing the circulation and greatly improving the service life of the motor. At the same time, it greatly reduces the energy loss of the motor due to the cooling oil. (2) The present invention designs two bearing seats. The bearing seats have an oil chamber and an annular groove in the center. The oil chamber and the annular groove form a closed cavity. After the cooling oil sprayed on the bearing body is cooled, it falls onto the annular groove, which is the bottom of the entire closed cavity. The closed cavity has a sealing effect to prevent the cooling oil from being exposed. It can also be transported by the circulation mechanism to prevent it from accumulating in the closed cavity and preventing the accumulated cooling oil from submerging the bearing body, thereby greatly reducing the energy loss of the motor. The cooling oil is widely covered by multiple nozzles to cool the dead corners of the bearing body by consuming its rotational force and preventing the cooling oil from consuming the rotational force of the bearing body, thus greatly improving the performance of the motor. (3) The present invention designs a fan located above the oil pipe. When the shaft rotates, it drives the fan to rotate, so that the fan can cool the oil pipe. Since the top of the upper cover has heat dissipation holes, the cold air from the outside is sent into the motor, which not only cools the multiple parts inside the motor, but also cools the cold air in the oil pipe, thus cooling the heated cooling oil in the oil pipe. The cooled cooling oil can continue to cool the bearing body, realizing the cycle of use and greatly improving the service life of the motor. (4) The present invention designs a rotor. When the motor is in use, after the motor is powered on, a magnetic field that rotates continuously in space will be generated inside the iron core. This rotating magnetic field will pass through the air gap and act on the rotor. The rotor starts to rotate from a stationary state, thus driving the shaft to rotate. The bottom end of the shaft is the output end, thus realizing the rotation of the external equipment. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] like Figures 1-7As shown, this embodiment of an energy-saving vertical motor structure with bearing oil cooling includes a housing 1. Sealing shells 11 are fixedly connected to the center of both sides of the housing 1. Shaft seats 12 are fixedly connected to the top and bottom of the housing 1. An oil chamber 121 is provided at the center of the interior of the shaft seat 12. Multiple mounting holes 122 are provided at the top of the shaft seat 12. An annular inclined groove 123 is provided inside the shaft seat 12 and at the bottom end of the oil chamber 121. Spray nozzles 124 are fixedly installed in each of the multiple mounting holes 122. The top of each spray nozzle 124... A mounting pipe 125 is fixedly connected between the bearing and the motor. When the motor is driven, the cooling oil in the oil pipe 112 is drawn out through the circulation mechanism 2 and then transported to the mounting pipe 125, thereby supplying it to multiple nozzles 124. The multiple nozzles 124 then spray the cooling oil onto the bearing body 142, achieving cooling and reducing the temperature of the bearing body 142. As the spray continues onto the bearing body 142, the heated cooling oil falls onto the annular inclined groove 123 and accumulates. At this point, the circulation mechanism 2 draws it out and returns it to the oil pipe 112. The oil is transported internally, and the oil pipe 112 cools and circulates, continuously cooling the bearing body 142. The cooling oil not only cools the bearing body 142, but also forms a very thin oil film between the bearing rolling elements and raceways, significantly reducing frictional resistance and increasing the rotational speed of the shaft 141, thereby improving the motor's efficiency. The oil chamber 121 and the annular inclined groove 123 form a sealed cavity. After being cooled, the cooling oil sprayed on the bearing body 142 falls onto the annular inclined groove 123, which is the bottom of the sealed cavity. The sealed cavity has a sealing effect, preventing the cooling oil from leaking out, and it can be transported by the circulation mechanism 2 to prevent it from accumulating in the sealed cavity and submerging the bearing body 142, thus greatly reducing the consumption of its rotational power. The cooling oil is sprayed by multiple nozzles 124, making the cooling oil coverage wide, thereby cooling the dead corners, while also preventing the cooling oil from consuming the rotational power of the bearing body 142, greatly improving the motor's performance.

[0029] like Figures 1-7 As shown, a support frame 111 is fixedly connected to the bottom of the inner wall of the upper cover 13, and an oil pipe 112 is fixedly installed on the top of the support frame 111. When using the motor equipment, the operator can add cooling oil into the oil pipe 112. When the entire motor is running, the cooling oil can be transported to the corresponding bearing 12 through two circulation mechanisms 2, thereby cooling the motor parts. The cooling oil in the oil pipe 112 is circulating, which can continuously cool the motor and greatly improve the service life of the motor. The upper cover 13 is located on the outside of the bearing 12 at the top of the housing 1, and the lower cover 15 is located on the outside of the bearing 12 at the bottom of the housing 1.

[0030] like Figures 1-7As shown, a rotor 14 is located at the center of the housing 1. A rotating shaft 141 is fixedly connected to the center of the rotor 14. Bearing bodies 142 are fixedly installed at the top and bottom of the outer wall of the rotating shaft 141. An iron core 143 is fixedly connected to the inner wall of the housing 1. The rotor 14 is located at the center of the iron core 143. When the motor is in use, after the motor is powered on, a magnetic field that rotates continuously in space is generated inside the iron core 143. This rotating magnetic field passes through the air gap and acts on the rotor 14, causing the rotor 14 to start rotating from a stationary position, thereby driving the rotating shaft 141 to rotate. The bottom end of the rotating shaft 141 is the output end, thereby realizing the rotation of external equipment. The entire rotor 14 is installed between two bearing seats 12 through two bearing bodies 142, and then installed in the housing 1. The two bearing bodies 142 are located in corresponding oil chambers 121. The two oil chambers 121 cool the corresponding bearing bodies 142. The two bearing bodies 142 are cooled simultaneously, thereby improving the cooling of the rotating shaft 141 and thus providing efficient heat dissipation for the motor.

[0031] like Figures 1-5 As shown, a lower end cover 15 is fixedly connected to the bottom of the housing 1, and a flange 151 is fixedly connected to the bottom of the lower end cover 15. The entire motor can be connected to external equipment through the flange 151, and then assembled and connected by multiple fixing bolt assemblies to improve the stability of the connection.

[0032] A top cover 13 is fixedly connected to the top of the housing 1. A fan 113 is fixedly installed inside the top cover 13. The fan 113 is located above the oil pipe 112. When the shaft 141 rotates, it drives the fan 113 to rotate, so that the fan 113 blows air to cool the oil pipe 112. Since the top of the top cover 13 has heat dissipation holes, cold air from the outside is sent into the motor, which not only cools down multiple parts inside the motor, but also cools down the cold air in the oil pipe 112, thereby cooling down the heated cooling oil in the oil pipe 112. The cooled cooling oil can then continue to cool down the bearing body 142, realizing recycling and greatly improving the service life of the motor.

[0033] like Figures 1-6As shown, two circulation mechanisms 2 are installed inside the two sealed housings 11. Each circulation mechanism 2 includes a first pump body 201 fixedly connected to one of the sealed housings 11, a first connecting pipe 202 fixedly connected to the first pump body 201 and the oil pipe 112, and a second connecting pipe 203 fixedly connected to the first pump body 201 and the mounting pipe 125. A second pump body 204 is fixedly installed inside the other sealed housing 11, and a third connecting pipe 205 fixedly connected to the second pump body 204 and the oil pipe 112. The second pump body 204 is also fixedly connected to the bottom of the annular inclined groove 123. Connected to the fourth connecting pipe 206, when spraying oil to cool the bearing body 142, the first pump 201 is started, drawing low-temperature cooling oil from one end of the oil pipe 112 through the first connecting pipe 202, and then delivering it to the mounting pipe 125 through the second connecting pipe 203. This causes the mounting pipe 125 to deliver the cooling oil to multiple nozzles 124, finally spraying it onto the bearing body 142 to cool it. The cooling oil that falls onto the annular inclined groove 123, where its temperature rises due to heating, triggering the second pump 204. Cooling oil is drawn from the bottom of the annular inclined groove 123 through the fourth connecting pipe 206 and transported to the other end of the oil pipe 112 through the third connecting pipe 205, thus sending the high-temperature cooling oil back into the oil pipe 112. The fan 113 then cools the oil, and since the fan 113 can cover the entire oil pipe 112, and the cooling oil within the oil pipe 112 can circulate, the high-temperature cooling oil at the other end of the oil pipe 112 continues to cool. After cooling, under the action of the first pump body 201, it flows to one end, facilitating subsequent continuous spraying of cooling solution onto the bearing body 142. The oil pipe 112 is then cooled. The cooling oil flows through one end to the first pump body 201 and the mounting pipe 125. The cooling oil above the annular inclined groove 123 flows through the fourth connecting pipe 206, the second pump body 204 and the third connecting pipe 205 to the other end of the oil pipe 112. This allows the cooling oil in the oil pipe 112 to spray and cool the bearing body 142 under the action of the first pump body 201. After cooling, the cooling oil flows back to the oil pipe 112 under the action of the second pump body 204 to cool it, thus achieving recycling. This greatly improves the service life of the motor and also greatly reduces the energy loss of the motor due to the cooling oil.

[0034] The working principle of this embodiment is as follows: the entire motor can be connected to an external device through flange 151, and then assembled and connected through multiple fixing bolt assemblies, which is convenient for installation; When the motor is in use, after the motor is powered on, a magnetic field that rotates continuously in space is generated inside the iron core 143. This rotating magnetic field passes through the air gap and acts on the rotor 14, causing the rotor 14 to start rotating from a standstill, thereby driving the rotating shaft 141 to rotate. The bottom end of the rotating shaft 141 is the output end, thereby realizing the rotation of external equipment. The entire rotor 14 is mounted between two bearing seats 12 through two bearing bodies 142 and is installed inside the housing 1. After the motor is used, the temperature of its shaft 141 rises, causing the temperature of the bearing body 142 to rise as well. At this time, the first pump 201 is activated, drawing cooler oil from one end of the oil pipe 112 through the first connecting pipe 202. This oil is then transported to the mounting pipe 125 through the second connecting pipe 203. The mounting pipe 125 then delivers the cooler oil to multiple nozzles 124, finally spraying it onto the bearing body 142 to cool it down. Because the oil chamber 121 and the annular inclined groove 123 form a closed cavity, the sprayed oil onto the bearing body 142... After the cooling oil is cooled, it first falls onto the annular inclined groove 123, which is the bottom of the entire sealed cavity. The sealed cavity has a sealing effect to prevent the cooling oil from leaking out. It can also be transported by the circulation mechanism 2 to prevent it from accumulating in the sealed cavity and to prevent the accumulated cooling oil from submerging the bearing body 142, thereby greatly reducing the consumption of its rotational power. The cooling oil is sprayed by multiple nozzles 124 to achieve a wide coverage area, thereby cooling the dead corners. At the same time, it prevents the cooling oil from consuming the rotational power of the bearing body 142, greatly improving the performance of the motor. Cooling oil that is in contact with the bearing body 142 falls onto the annular inclined groove 123. At this time, the cooling oil is heated and its temperature rises. The second pump body 204 is started, and the cooling oil at the bottom of the annular inclined groove 123 is drawn through the fourth connecting pipe 206 and transported to the other end of the oil pipe 112 through the third connecting pipe 205. This returns the high-temperature cooling oil to the oil pipe 112, realizing recycling and greatly improving the service life of the motor. At the same time, it greatly reduces the energy loss of the motor due to the cooling oil. When the motor is driven, the rotating shaft 141 rotates, driving the fan 113 to rotate, so that the fan 113 delivers air to the oil pipe 112 for cooling. Since the top of the upper cover 13 has heat dissipation holes, cold air from the outside is sent into the motor, which not only cools down multiple parts inside the motor, but also cools down the cold air in the oil pipe 112. Since the air delivered by the fan 113 can cover the entire oil pipe 112, and the cooling oil in the oil pipe 112 can circulate with each other, the high temperature cooling oil at the other end of the oil pipe 112 is continuously cooled. After cooling, under the action of the first pump body 201, it flows to one end, which facilitates the subsequent continuous spraying of cooling on the bearing body 142.

[0035] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
