Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving motors, and more specifically to an integrated motor for mechanical transmission. Background Art

[0002] The integrated motor for mechanical transmission is an innovative design that closely combines a motor with a mechanical transmission structure; this design not only reduces energy losses in the traditional transmission system but also significantly reduces the volume and weight of the equipment. The integrated motor is widely used in fields such as industrial automation, robotics, and new energy vehicles, demonstrating excellent performance and reliability; The patent with the application number CN201310495354.3 discloses a gear motor for driving a toilet seat and a toilet lid, which can be assembled at low cost. The gear motor includes a housing composed of three components and houses a DC motor, a reduction gear set, and an angle sensor. The housing is composed of three components: a cover, an upper housing, and a lower housing that overlap vertically. The support shafts of the output gear in the reduction gear set and the fourth gear that meshes with it and meshes with the sensor gear of the angle sensor are supported by the upper housing and the lower housing, and the angle sensor is arranged in the space between the cover and the upper housing; Most of the existing devices connect the gear transmission components to the motor. However, the mutual friction between the gears will cause the gears to gradually wear. The gear wear will further lead to unstable transmission, which will in turn affect the transmission, resulting in a relatively short service life of the entire device. Summary of the Invention

[0003] In view of the deficiencies of the prior art, the present invention provides an integrated motor for mechanical transmission to solve the problems raised in the above background art.

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: An integrated motor for mechanical transmission includes a motor. A transmission component is fixedly connected to the left side of the motor. A cooling component is fixedly connected to the outer wall of the transmission component. A filtering component is fixedly connected to the outer wall of the cooling component; The cooling component includes: A suction pipe fixedly connected to the outer wall of the transmission component; An eccentric sleeve arranged on the outer wall of the output shaft of the motor; A return pipe fixedly connected to the outer wall of the transmission component.

[0005] Preferably, the transmission assembly includes a first sealing end disposed on the left side of the motor. An output shaft is movably connected inside the first sealing end through a bearing. A planet carrier and planet gears are arranged on the right side of the output shaft. An external gear ring is fixedly connected to the right side of the first sealing end. A second sealing end is fixedly connected to the right side of the external gear ring. An input shaft is movably connected inside the second sealing end through a bearing. A sun gear is fixedly connected to the left side of the input shaft. When in use, the motor is fixed to an external fixed structure, and at the same time, the first sealing end is fixed to the external structure. When the motor starts, it drives the input shaft to rotate through its own output shaft. The input shaft drives the planet gears to rotate through the sun gear, and then the planet gears drive the output shaft to rotate through the action with the external gear ring, increasing the torque of the motor and outputting power outward.

[0006] Preferably, the filtering assembly includes a filtering box. A driving pipe is fixedly connected to the right side of the filtering box. A filter net is fixedly connected to the outer wall of the filtering box at a position corresponding to the driving pipe. The V-shaped plate is fixedly connected to the outer wall of the planet carrier on the right side of the output shaft.

[0007] Preferably, the suction pipe is fixedly connected to the outer wall of the external gear ring. A connecting pipe is fixedly connected to the right side of the driving pipe. The connecting pipe is fixedly connected to the outer wall of the eccentric sleeve. The outer wall of the return pipe is fixed to the eccentric sleeve. The return pipe is fixedly connected to the top of the external gear ring.

[0008] Preferably, an inner runner is movably connected inside the eccentric sleeve. The inner runner is fixedly connected to the output shaft of the motor. Six oil pumping pieces are movably connected inside the inner runner. A spring is fixedly connected to the side of each oil pumping piece close to the inner runner. The outer wall of the eccentric sleeve is fixedly connected to the outer wall of the second sealing end through a connecting rod. When the motor rotates, it drives the inner runner to rotate through the output shaft. When the inner runner rotates, it drives the corresponding oil pumping pieces to rotate. Since the eccentric sleeve is fixed to the outside and cannot be driven to rotate, when the oil pumping pieces rotate from the connecting pipe to the return pipe, the oil pumping pieces will be gradually compressed inward, reducing the space between the two oil pumping pieces, and then pumping the lubricating oil into the eccentric sleeve through the suction pipe and then into the return pipe, and then pumping it back into the interior from the return pipe.

[0009] Preferably, several heat dissipation fins are fixedly connected to the right side of the eccentric sleeve. A spiral blade is fixedly connected to the output shaft of the motor on the right side of the heat dissipation fins.

[0010] Preferably, a sweeping piece is movably connected to the left side of the filter net. A driving blade is fixedly connected to the right side of the sweeping piece through a short shaft.

[0011] Preferably, a bottom sealing plate is fixedly connected to the bottom of the filtering box through screws. A threaded plug is movably connected to the top of the filtering box through threads. Unscrew the threaded plug to balance the air pressure inside the filtering box and facilitate the outflow of part of the lubricant.

[0012] The present invention provides an integrated motor with mechanical transmission. It has the following beneficial effects: 1. For this integrated motor with mechanical transmission, the inner runner is driven to rotate by the motor. Lubricating oil is pumped into the eccentric sleeve through the suction pipe and then pumped to the return pipe, and then pumped back into the interior from the return pipe. The lubricating oil pumped out from the return pipe will drip onto the rotating planet gears, and the lubricating oil deposited at the bottom is dripped onto the rotating planet gears, thus playing a role in making the lubricating oil more evenly distributed, enhancing the lubrication effect of the lubricating oil, and being able to reduce tooth wear.

[0013] 2. For this integrated motor with mechanical transmission, by allowing the lubricating oil to enter the eccentric sleeve, the heat sink will absorb the heat of the lubricating oil, and the spiral blades rotate to push the air flow through the heat sink to dissipate heat from the lubricating oil. At the same time, the lubricating oil will be slightly compressed inside the eccentric sleeve, thereby increasing the temperature difference between the lubricating oil and the external air flow, increasing the heat transfer, making the lubricating oil have a lower temperature when it returns to its original volume, avoiding the deterioration of the lubrication effect due to the increase in the temperature of the lubricating oil, and being able to reduce tooth wear.

[0014] 3. For this integrated motor with mechanical transmission, through the rotation of the V-shaped plate, the internal metal debris is stuck at the bend of the V, and the debris is pushed into the suction pipe at the bend of the V by centrifugal force. The debris enters the filter box along with the lubricating oil from the suction pipe, and then flows towards the drive pipe after passing through the filter box, so that the debris is filtered by the filter net, thereby intercepting the debris in the lubricating oil inside the filter box, reducing the amount of metal debris in the lubricating oil, and avoiding the participation of metal debris in wear during the gear movement with the lubricating oil, being able to reduce tooth wear.

[0015] 4. For this integrated motor with mechanical transmission, by unscrewing the threaded plug, the air pressure inside the balance filter box is made convenient for part of the lubrication to flow out. Then, by unscrewing the screws fixing the bottom sealing plate, the debris in the lubricating oil filtered by the filter net can be cleaned out, avoiding excessive accumulation of the debris, improving the continuous filtering effect, and being able to reduce tooth wear.

[0016] 5. For this integrated motor with mechanical transmission, the metal debris in the lubricating oil is intercepted by the filter net, and the debris is cleaned by disassembling the bottom sealing plate, avoiding the debris flowing into the pipes of the cooling component, preventing the pipes in the cooling component from being blocked, and preventing the debris from causing wear to the internal structure of the cooling component. Furthermore, it can improve the cooling effect of the cooling component mechanism on the lubricating oil and reduce tooth wear. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation of the present invention.

[0021] Embodiment 1: Please refer to Figure 1-9 , the present invention provides a technical solution: an integrated mechanical transmission motor, including a motor 1, a transmission component 2 is fixedly connected to the left side of the motor 1, a cooling component 3 is fixedly connected to the outer wall of the transmission component 2, and a filter component 4 is fixedly connected to the outer wall of the cooling component 3; The cooling assembly 3 includes: A suction pipe 301, which is fixedly connected to the outer wall of the transmission assembly 2; An eccentric sleeve 303, which is arranged on the outer wall of the output shaft of the motor 1; A return pipe 304, which is fixedly connected to the outer wall of the transmission assembly 2.

[0022] The transmission assembly 2 includes a first sealing end 201, which is arranged on the left side of the motor 1. An output shaft 204 is movably connected inside the first sealing end 201 through a bearing. A planet carrier and planet gears are arranged on the right side of the output shaft 204. An outer gear ring 203 is fixedly connected to the right side of the first sealing end 201. A second sealing end 202 is fixedly connected to the right side of the outer gear ring 203. An input shaft 205 is movably connected inside the second sealing end 202 through a bearing. A sun gear is fixedly connected to the left side of the input shaft 205. The first sealing end 201, the outer gear ring 203 and the second sealing end 202 form a sealed space through the corresponding bearings, and lubricating oil is filled into this sealed space before use.

[0023] When in use, the motor 1 is fixed to an external fixed structure, and at the same time, the first sealing end 201 is fixed to the external structure. When the motor 1 starts, it drives the input shaft 205 to rotate through its own output shaft. The input shaft 205 drives the planet gears to rotate through the sun gear, and then the planet gears drive the output shaft 204 to rotate through the action with the outer gear ring 203, increasing the torque of the motor 1 to output power outward.

[0024] The suction pipe 301 is fixedly connected to the outer wall of the outer gear ring 203. A connecting pipe 302 is fixedly connected to the right side of the drive pipe 402. The connecting pipe 302 is fixedly connected to the outer wall of the eccentric sleeve 303. The outer wall of the return pipe 304 is fixedly connected to the eccentric sleeve 303. The return pipe 304 is fixedly connected to the top of the outer gear ring 203.

[0025] An inner runner 307 is movably connected inside the eccentric sleeve 303. The inner runner 307 is fixedly connected to the output shaft of the motor 1. The circle of the eccentric sleeve 303 is not on the axis of the output shaft of the motor 1, and the circle of the inner runner 307 is on the axis of the output shaft of the motor 1. Six oil pumping vanes 308 are movably connected inside the inner runner 307. A spring 309 is fixedly connected to one side of each oil pumping vane 308 close to the inner runner 307. The outer wall of the eccentric sleeve 303 is fixedly connected to the outer wall of the second sealing end 202 through a connecting rod.

[0026] When the motor 1 rotates, it will drive the inner runner 307 to rotate through the output shaft. When the inner runner 307 rotates, it will drive the corresponding oil pumping piece 308 to rotate. Since the eccentric sleeve 303 is fixed to the outside and cannot be driven to rotate, when the oil pumping piece 308 rotates from the connecting pipe 302 to the return pipe 304, the oil pumping piece 308 will be gradually compressed inward, reducing the space between the two oil pumping pieces 308. As a result, the lubricating oil is pumped into the inside of the eccentric sleeve 303 through the suction pipe 301 and then pumped to the return pipe 304. Then, it is pumped back to the inside from the return pipe 304, and the lubricating oil pumped out from the return pipe 304 will drip onto the rotating planet gears, thus playing a role in making the lubricating oil more evenly distributed.

[0027] On the right side of the eccentric sleeve 303, several heat dissipation fins 305 are fixedly connected, and on the right side of the heat dissipation fins 305, a spiral blade 306 is fixedly connected to the output shaft of the motor 1.

[0028] As the internal gears rotate, the temperature of the lubricating oil will increase accordingly. When the lubricating oil enters the inside of the eccentric sleeve 303, the heat will be absorbed by the heat dissipation fins 305, and the output shaft of the motor 1 rotates to drive the spiral blade 306 to rotate, allowing the air flow to pass through the heat dissipation fins 305 to dissipate heat from the lubricating oil. At the same time, the lubricating oil will be slightly compressed inside the eccentric sleeve 303, thereby increasing the temperature difference between the lubricating oil and the external air flow, and further increasing the heat transfer, so that the lubricating oil will have a lower temperature when it returns to its original volume, thus avoiding the deterioration of the lubricating effect due to the increase in the temperature of the lubricating oil.

[0029] Embodiment 2: Please refer to Figure 1-10 , based on Embodiment 1, the present invention provides the following technical solution: The filtering assembly 4 includes a filtering box 401. On the right side of the filtering box 401, a driving pipe 402 is fixedly connected. On the outer wall of the filtering box 401 at the corresponding position of the driving pipe 402, a filter net 403 is fixedly connected. The V-shaped plate 406 is fixedly connected to the outer wall of the planet carrier on the right side of the output shaft 204.

[0030] The V-shaped plate 406 will be driven to rotate by the planet carrier on the rotating output shaft 204. When the V-shaped plate 406 rotates, the internal metal debris will be caught at the bend of the V by the centrifugal force, and the debris will be pushed into the suction pipe 301 at the bend of the V by the centrifugal force, allowing the debris to enter the inside of the filtering box 401 along with the lubricating oil from the suction pipe 301. Then, it will flow from the filtering box 401 to the driving pipe 402, and when flowing from the filtering box 401 into the inside of the driving pipe 402, it will be filtered by the filter net 403, thereby intercepting the debris in the lubricating oil inside the filtering box 401.

[0031] On the left side of the filter net 403, a sweeping piece 404 is movably connected. Through a short shaft, a driving blade 405 is fixedly connected to the right side of the filter net 403.

[0032] When the lubricating oil flows from the drive pipe 402 through the filter cartridge 401, it will push the drive blade 405, and through the short shaft, the sweeping blade 404 will rotate to sweep one side of the filter net 403 located in the filter cartridge 401, so as to prevent the filter net 403 from being blocked and ensure the smooth flow of the lubricating oil.

[0033] The bottom of the filter cartridge 401 is fixedly connected with a bottom sealing plate 407 by screws, and the top of the filter cartridge 401 is movably connected with a threaded plug 408 by threads. When the motor stops working, by unscrewing the threaded plug 408, the air pressure inside the balance filter cartridge 401 is made convenient for part of the lubricant to flow out. Then, by unscrewing the screws fixing the bottom sealing plate 407, the debris in the lubricating oil filtered by the filter net 403 can be cleaned out to avoid excessive accumulation of the debris.

[0034] The metal debris in the lubricating oil is intercepted by the filter net 403, and the debris is cleaned by disassembling the bottom sealing plate 407, so as to prevent the debris from flowing into the pipeline inside the cooling component 3, avoid the blockage of the pipeline in the cooling component 3, and prevent the wear of the internal structure of the cooling component 3 caused by the debris. Furthermore, the cooling effect of the cooling component 3 mechanism on the lubricating oil can be improved.

[0035] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
