Description

Technical Field

[0001] This invention belongs to the field of sealed motor technology, specifically relating to a sealed, high-efficiency, energy-saving geared motor. Background Technology

[0002] A sealed motor is a power unit that encloses the motor body, windings, bearings, and other core components within an integrated sealed structure. By isolating the motor from dust, moisture, corrosive media, and impurities in the external environment, it prevents internal components from being corroded or damaged, significantly improving operational stability and service life. Its structural design balances sealing and heat dissipation requirements, allowing it to operate continuously in harsh conditions such as humidity, dust, oil, and corrosion without frequent maintenance. During operation, the sealed internal space ensures insulation performance and mechanical precision, reducing potential malfunctions. Widely used in equipment and scenarios with high reliability and protection requirements, it combines durability, safety, and low maintenance, making it a key actuator for stable power output in industrial and special environments.

[0003] The difficulty in heat dissipation of sealed motors stems primarily from the isolation of their casing from the external environment. Heat generated by the internal windings and core cannot be quickly dissipated through air convection, and the sealed structure hinders heat conduction and exchange, leading to internal heat accumulation and elevated temperature. Existing sealed motors often increase heat dissipation efficiency by adding cooling fins to the casing surface to enhance heat conduction with the outside. While this method effectively improves heat dissipation, it relies mainly on natural convection through the casing and cooling fins or external air cooling. Heat is slowly dissipated from the outside of the stator, making it difficult to effectively remove heat from the inside of the stator core and the air gap region, leading to internal heat accumulation and higher temperature rise. Furthermore, this structure cannot create a directional, forced internal airflow circulation within the sealed cavity, resulting in a long and inefficient heat dissipation path. This can cause the permanent magnet rotor to remain in a high-temperature environment for extended periods, increasing the risk of demagnetization, raising stator winding temperature, increasing copper and iron losses, and reducing motor efficiency and reliability. 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 a sealed, high-efficiency, energy-saving geared motor.

[0005] The technical solution adopted to solve the above technical problems is: a sealed high-efficiency energy-saving geared motor, including a housing mechanism, a stator mechanism, a heat-conducting boss mechanism, a heat-conducting plate mechanism, a rotor mechanism, a cover mechanism and a reduction mechanism. The housing mechanism includes a housing body. Multiple support bosses are integrally fixed on the inner side of the housing mechanism. A boss positioning groove is opened on the upper part of the support boss. A heat pipe assembly is embedded and fixed on the inner side of the support boss. A heat-conducting substrate is fixed at one end of the heat pipe assembly.

[0006] A stator mechanism is fixed inside the housing mechanism, and multiple heat-conducting boss mechanisms are fixed in a circumferential array on the surface of the stator mechanism. Heat-conducting plate mechanisms are inserted into the heat-conducting boss mechanisms, and a rotor mechanism is rotatably connected inside the housing mechanism.

[0007] The rotor mechanism includes a rotor body, the outer wall of which has multiple axial grooves, a rotor shaft fixed at the center of the rotor body, an exhaust blade coaxially fixed on the rotor shaft, a cover mechanism screwed to one end of the housing mechanism, and a speed reduction mechanism screwed to the end of the cover mechanism away from the housing mechanism.

[0008] Furthermore, the plurality of supporting bosses are arranged in an equidistant circular array, and the heat-conducting substrate is embedded in the inner wall of the boss positioning groove.

[0009] Through the above technical solution, the shell body and the supporting boss can be made of high-strength and heat-dissipating materials such as die-cast aluminum alloy or stainless steel, and the heat-conducting substrate is made of pure copper. The surface of the heat-conducting substrate is flush with or slightly higher than the inner wall surface of the boss positioning groove.

[0010] Furthermore, a first heat dissipation fin is integrally fixed to the outside of the housing body. The first heat dissipation fin consists of a circumferential fin and multiple axial fins. A first bearing is fixed to one end of the inside of the housing body. Multiple first screw slots are integrally fixed to the housing body. A first sealing ring is embedded in the open end of the housing body.

[0011] Through the above technical solution, the circumferential fins and multiple axial fins effectively increase the heat dissipation area of ​​the housing body. The end of the heat pipe assembly is attached to the first heat dissipation fin, and the heat pipe assembly can quickly conduct the heat of the heat-conducting substrate to the first heat dissipation fin.

[0012] Furthermore, the stator mechanism includes a heat-conducting bushing disposed inside the housing body. The outer wall of the heat-conducting bushing has multiple boss fixing slots arranged in an equidistant circular array. The inner side of the heat-conducting bushing is fitted with a stator core, and a stator winding is wound on the stator core.

[0013] Through the above technical solution, the heat-conducting bushing can be made of pure copper, which has excellent thermal conductivity. After the stator winding is energized, a rotating alternating magnetic field will be generated inside the stator core.

[0014] Furthermore, the heat-conducting boss mechanism includes a heat-conducting boss body embedded and fixed inside the boss fixing groove. The heat-conducting boss body is made of pure copper. The heat-conducting boss body and the boss fixing groove are connected by an interference fit. The contact part between the heat-conducting boss body and the boss fixing groove is filled with heat-conducting adhesive. Side slots are provided on both sides of the heat-conducting boss body.

[0015] Through the above technical solution, the heat-conducting boss body can conduct the heat of the heat-conducting bushing radially outward. The heat-conducting bushing and the heat-conducting boss body, along with the interference fit and heat-conducting adhesive filling structure, effectively improve the heat conduction efficiency between the heat-conducting bushing and the heat-conducting boss body. The thickness of the heat-conducting boss body and the supporting boss makes an air-circulating interlayer formed between the inner wall of the housing body and the outer wall of the heat-conducting bushing. Furthermore, the temperature of the outer wall of the stator core can be normally conducted to the housing body and the first heat dissipation fins through the heat-conducting bushing, the heat-conducting boss body, and the supporting boss.

[0016] Furthermore, the heat-conducting sheet mechanism includes a heat-conducting sheet body, both ends of which are integrally fixed with fitting inserts. The fitting inserts are inserted into the side slots, and the contact area between the fitting inserts and the side slots is filled with thermally conductive adhesive.

[0017] Through the above technical solution, the heat-conducting sheet mechanism connects the sides of each heat-conducting protrusion body, so that the heat between the heat-conducting protrusion bodies can be conducted to each other, and the heat-conducting sheet mechanism can also absorb heat from the air and conduct it to the heat-conducting protrusion body.

[0018] Furthermore, an input gear is coaxially fixed to one end of the rotor shaft, and the end of the rotor shaft away from the input gear is fixed to the inner ring of the first bearing. The plurality of axial inclined slots are equidistantly distributed in a circular pattern.

[0019] Through the above technical solution, the rotor body is a permanent magnet rotor, which generates almost no heat. When the stator winding is energized, the alternating magnetic field causes the rotor body to rotate at high speed. When the rotor body rotates at high speed, the axial slots cause the airflow at the air gap between the rotor body and the stator core to generate high-speed axial flow. At the same time, the rotor shaft and the exhaust blades also rotate at high speed. The exhaust blades further increase the airflow and velocity at the air gap between the rotor body and the stator core, thereby carrying away the heat from the inside of the stator core. The airflow moves along the axial direction, and after contacting the inner side of the cover body, it turns back and flows into the interlayer between the inner wall of the housing body and the outer wall of the heat-conducting bushing. The heat-containing gas comes into contact with the heat-conducting boss body and the heat-conducting plate mechanism. When touched, heat is conducted to the heat-conducting boss body and the heat-conducting plate mechanism. The heat from the heat-conducting boss body can then be quickly conducted to the first heat dissipation fins through the heat-conducting substrate and heat pipe assembly. The heat is then radiated into the air through the first heat dissipation fins, enabling the device to efficiently dissipate heat from the inside of the stator core. This reduces the risk of high-temperature demagnetization of the rotor body and lowers the temperature of the stator windings and stator core, reducing copper and iron losses and improving motor operating efficiency. Under the same output, power consumption is lower, thus achieving energy saving. After passing through the heat-conducting boss body and the heat-conducting plate mechanism, the airflow reaches the rear end of the housing body and is again driven by the axial inclined slot and exhaust blades, realizing the internal airflow circulation and heat dissipation of the device.

[0020] Furthermore, the cover mechanism includes a cover body, one end of which is bonded with a thermally conductive silicone sheet, and the cover body has a rubber ring groove. Multiple second heat dissipation fins are arranged in an equidistant circular array on the outer side of the cover body.

[0021] With the above technical solution, the inner end face of the cover body is arc-shaped. When the airflow comes into contact with the cover body, it will turn and fold back along the arc direction of the cover body. The arc-shaped structure effectively reduces the turning resistance of the gas. When the airflow comes into contact with the cover body, its heat will also be conducted to the cover body and radiated into the air through the second heat dissipation fins.

[0022] Furthermore, a second bearing is embedded and fixed on the inner side of the cover body, a plurality of second screw slots are provided on the cover body, a plurality of connecting ears are integrally fixed on the outer side of the cover body, a first fastening screw is provided on the inner side of the connecting ears, the first fastening screw is threadedly connected to the first screw slot, and the inner ring of the second bearing is fixed to the rotor shaft.

[0023] With the above technical solution, after tightening the first fastening screw, the cover mechanism and the housing mechanism can be pressed and fixed together. At this time, the first sealing ring is pressed by the cover mechanism and the housing mechanism, which can effectively ensure the sealing performance of the device.

[0024] Furthermore, the reduction mechanism includes a reducer housing, on the outside of which multiple third heat dissipation fins are integrally fixed. A heat-conducting groove is formed on the reducer housing, and a second sealing ring is also embedded in the reducer housing. An output shaft is rotatably connected to one end of the reducer housing. Multiple second fastening screws pass through the reducer housing and are threaded into second screw slots. A planetary reduction gear set is rotatably connected inside the reducer housing. The planetary gears of the planetary reduction gear set mesh with the input gear, and the output planet carrier of the planetary reduction gear set is coaxially fixed to the output shaft.

[0025] With the above technical solution, after tightening the second fastening screw, the reduction mechanism and the cover mechanism will be pressed together. At this time, the second sealing ring is pressed into the rubber ring groove, thereby achieving a seal between the reduction mechanism and the cover mechanism. The heat-conducting silicone sheet is pressed into the heat-conducting plate groove and fits tightly against the inner wall of the heat-conducting plate groove, so that the heat of the cover mechanism can be efficiently conducted to the reducer housing and radiated into the air through the third heat dissipation fins. This allows the device to use the reducer housing for heat dissipation, further improving the external heat dissipation area and heat dissipation efficiency of the device. When the rotor shaft rotates, the input gear will also rotate, thereby driving the planetary reduction gear set to operate. The planetary reduction gear set can reduce the output speed of the device and increase its torque, and output power through the output shaft.

[0026] The beneficial effects of this invention are as follows:

[0027] 1. The present invention, through the arrangement of the shell mechanism, stator mechanism, heat-conducting boss mechanism, heat-conducting plate mechanism and rotor mechanism, realizes the axial circulation of gas in the air gap of stator and rotor, and can efficiently conduct the heat in the gas to the outside of the device during the circulation process, thereby improving the heat dissipation efficiency inside the iron core, reducing copper loss and iron loss, and reducing energy consumption.

[0028] 2. By setting up a cover mechanism and a deceleration mechanism, the present invention enables the device to dissipate heat not only through the housing and cover, but also through the outer shell of the decelerator, effectively increasing the heat dissipation area and further improving the heat dissipation efficiency.

[0039] 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.

[0040] like Figures 1-9As shown, a sealed, high-efficiency, energy-saving geared motor includes a housing mechanism 1, a stator mechanism 2, a heat-conducting boss mechanism 3, a heat-conducting plate mechanism 4, a rotor mechanism 5, a cover mechanism 6, and a reduction mechanism 7. The housing mechanism 1 includes a housing body 101. Multiple support bosses 102 are integrally fixed on the inner side of the housing mechanism 1. Boss positioning grooves 103 are opened on the upper part of the support bosses 102. Heat pipe groups 108 are embedded and fixed on the inner side of the support bosses 102. A heat-conducting substrate 109 is fixed to one end of the heat pipe group 108. The multiple support bosses 102 are arranged in an equidistant circular array. The heat-conducting substrate 109 is embedded in the inner wall of the boss positioning groove 103. A first heat dissipation fin 104 is integrally fixed on the outer side of the housing body 101. The first heat dissipation fin 104 is composed of a circumferential fin and multiple axial fins. The housing body 101 has a first bearing 105 fixed at one end inside. The housing body 101 has multiple first screw slots 106 integrally fixed. The opening end of the housing body 101 is fitted with a first sealing ring 107. The housing body 101 and the supporting boss 102 can be made of high-strength and heat-dissipating materials such as die-cast aluminum alloy or stainless steel. The heat-conducting substrate 109 is made of pure copper. The surface of the heat-conducting substrate 109 is flush with or slightly higher than the inner surface of the boss positioning groove 103. The circumferential fins and multiple axial fins effectively increase the heat dissipation area of ​​the housing body 101. The end of the heat pipe assembly 108 is attached to the first heat dissipation fin 104. The heat pipe assembly 108 can quickly conduct the heat of the heat-conducting substrate 109 to the first heat dissipation fin 104.

[0041] like Figure 1 and Figure 4 As shown, a stator mechanism 2 is fixed inside the housing mechanism 1. The stator mechanism 2 includes a heat-conducting bushing 201 disposed inside the housing body 101. The outer wall of the heat-conducting bushing 201 is provided with multiple boss fixing slots 202, which are arranged in an equidistant circular array. A stator core 203 is sleeved inside the heat-conducting bushing 201. A stator winding 204 is wound on the stator core 203. The heat-conducting bushing 201 can be made of pure copper, which has excellent thermal conductivity. When the stator winding 204 is energized, a rotating alternating magnetic field is generated inside the stator core 203.

[0042] like Figure 1 and Figure 5As shown, the stator mechanism 2 has multiple heat-conducting boss mechanisms 3 fixed in a circumferential array on its surface. Each heat-conducting boss mechanism 3 includes a heat-conducting boss body 301 embedded and fixed inside the boss fixing groove 202. The heat-conducting boss body 301 is made of pure copper. The heat-conducting boss body 301 and the boss fixing groove 202 are connected by an interference fit. The contact portion between the heat-conducting boss body 301 and the boss fixing groove 202 is filled with thermally conductive adhesive. Side slots 302 are provided on both sides of the heat-conducting boss body 301. The heat-conducting boss body 301 can radially transfer the heat from the heat-conducting bushing 201 outwards. The heat-conducting bushing 201 and the heat-conducting boss body 301, along with the interference fit and heat-conducting adhesive filling structure, effectively improve the heat conduction efficiency between the heat-conducting bushing 201 and the heat-conducting boss body 301. The thickness of the heat-conducting boss body 301 and the supporting boss 102 creates an air-permeable interlayer between the inner wall of the housing body 101 and the outer wall of the heat-conducting bushing 201. Furthermore, the temperature of the outer wall of the stator core 203 can be normally conducted to the housing body 101 and the first heat dissipation fin 104 through the heat-conducting bushing 201, the heat-conducting boss body 301, and the supporting boss 102.

[0043] like Figure 1 and Figure 6 As shown, a heat-conducting plate mechanism 4 is inserted into the heat-conducting boss mechanism 3. The heat-conducting plate mechanism 4 includes a heat-conducting plate body 401. Both ends of the heat-conducting plate body 401 are integrally fixed with fitting inserts 402. The fitting inserts 402 are inserted into the side slots 302, and the contact area between the fitting inserts 402 and the side slots 302 is filled with heat-conducting adhesive. The heat-conducting plate mechanism 4 connects the sides of each heat-conducting boss body 301, so that the heat between the heat-conducting boss bodies 301 can be conducted to each other. The heat-conducting plate mechanism 4 can also absorb heat from the air and conduct it to the heat-conducting boss bodies 301.

[0044] like Figure 1 and Figure 7As shown, a rotor mechanism 5 is rotatably connected inside the housing mechanism 1. The rotor mechanism 5 includes a rotor body 501. Multiple axial grooves 502 are formed on the outer wall of the rotor body 501. A rotor shaft 503 is fixed at the axis of the rotor body 501. Exhaust blades 504 are coaxially fixed on the rotor shaft 503. An input gear 505 is coaxially fixed to one end of the rotor shaft 503. The end of the rotor shaft 503 away from the input gear 505 is fixed to the inner ring of the first bearing 105. The multiple axial grooves 502 are equidistantly distributed circumferentially. The rotor body 501 is a permanent magnet rotor, which generates almost no heat. When the stator winding 204 is energized, the alternating magnetic field causes the rotor body 501 to rotate at high speed. During this high-speed rotation, the axial skew slot 502 causes the airflow in the air gap between the rotor body 501 and the stator core 203 to flow at high speed. Simultaneously, the rotor shaft 503 and the exhaust blades 504 also rotate at high speed. The exhaust blades 504 further increase the airflow and velocity in the air gap between the rotor body 501 and the stator core 203, thereby drawing air from the inner side of the stator core 203. The heat is carried away, and the airflow moves axially. After contacting the inner side of the cover body 601, it turns back and flows into the interlayer between the inner wall of the shell body 101 and the outer wall of the heat-conducting bushing 201. When the heat-containing gas comes into contact with the heat-conducting boss body 301 and the heat-conducting plate mechanism 4, it conducts heat to the heat-conducting boss body 301 and the heat-conducting plate mechanism 4. The heat from the heat-conducting boss body 301 can then be quickly conducted to the first heat dissipation fin 104 through the heat-conducting substrate 109 and the heat pipe assembly 108, and the heat is radiated to the first heat dissipation fin 104. In the air, the device can efficiently dissipate heat from the inside of the stator core 203, thereby reducing the risk of high-temperature demagnetization of the rotor body 501, and reducing the temperature of the stator winding 204 and the stator core 203, reducing copper and iron losses, improving motor operating efficiency, and lowering power consumption under the same output, thus achieving energy saving. After passing through the heat-conducting boss body 301 and the heat-conducting plate mechanism 4, the airflow reaches the rear end of the housing body 101, and is again driven by the axial inclined groove 502 and the exhaust blade 504 to realize the airflow circulation and heat dissipation inside the device.

[0045] like Figure 1 and Figure 8As shown, a cover mechanism 6 is screwed to one end of the housing mechanism 1. The cover mechanism 6 includes a cover body 601, a thermally conductive silicone sheet 602 is bonded to one end of the cover body 601, a rubber ring groove 603 is formed on the cover body 601, a plurality of second heat dissipation fins 604 are arranged in an equidistant circular array on the outer side of the cover body 601, a second bearing 605 is embedded and fixed on the inner side of the cover body 601, a plurality of second screw grooves 606 are formed on the cover body 601, a plurality of connecting ears 607 are integrally fixed on the outer side of the cover body 601, a first fastening screw 608 passes through the inner side of the connecting ear 607, and the first fastening screw 608 is threadedly connected to the first screw groove 106. The inner ring of the second bearing 605 is fixed to the rotor shaft 503. The inner end face of the cover body 601 is arc-shaped. When the airflow comes into contact with the cover body 601, it will turn and fold back along the arc direction of the cover body 601. The arc structure effectively reduces the turning resistance of the gas. When the airflow comes into contact with the cover body 601, its heat will also be conducted to the cover body 601 and radiated into the air through the second heat dissipation fins 604. After tightening the first fastening screw 608, the cover mechanism 6 and the housing mechanism 1 can be pressed and fixed. At this time, the first sealing ring 107 is pressed by the cover mechanism 6 and the housing mechanism 1, which can effectively ensure the sealing of the device.

[0046] like Figure 1 , Figure 8 and Figure 9As shown, a reduction mechanism 7 is screwed to the end of the cover mechanism 6 away from the housing mechanism 1. The reduction mechanism 7 includes a reducer housing 701. Multiple third heat dissipation fins 702 are integrally fixed to the outside of the reducer housing 701. A heat conduction groove 703 is provided on the reducer housing 701. A second sealing ring 704 is also embedded on the reducer housing 701. An output shaft 705 is rotatably connected to one end of the reducer housing 701. Multiple second fastening screws 706 pass through the reducer housing 701 and are threaded into the second screw groove 606. A planetary reduction gear set 707 is rotatably connected inside the reducer housing 701. The planetary gears of the planetary reduction gear set 707 mesh with the input gear 505. The output planet carrier of the planetary reduction gear set 707 is coaxially fixed to the output shaft 705. Tighten the second fastening screws 704. After 06, the reduction mechanism 7 and the cover mechanism 6 will be pressed together. At this time, the second sealing ring 704 is pressed into the rubber ring groove 603, thereby achieving a seal between the reduction mechanism 7 and the cover mechanism 6. The heat-conducting silicone sheet 602 is pressed into the heat-conducting sheet groove 703 and fits tightly against the inner wall of the heat-conducting sheet groove 703, so that the heat of the cover mechanism 6 can be efficiently conducted to the reducer housing 701 and radiated into the air through the third heat dissipation fin 702. This allows the device to use the reducer housing 701 for heat dissipation, further improving the external heat dissipation area and heat dissipation efficiency of the device. When the rotor shaft 503 rotates, the input gear 505 will also rotate, thereby driving the planetary reduction gear set 707 to operate. The planetary reduction gear set 707 can reduce the output speed of the device and increase its torque, and output power through the output shaft 705.

[0047] The working principle of this embodiment is as follows: When using the device, the stator mechanism 2 is energized to generate a rotating alternating magnetic field, which causes the rotor mechanism 5 to rotate. When the rotor mechanism 5 rotates, the input gear 505 drives the planetary reduction gear set 707 to operate, which causes the output shaft 705 to rotate at low speed and high torque. During the operation, the rotating axial inclined groove 502 and the exhaust blade 504 will cause the gas in the air gap between the stator mechanism 2 and the rotor mechanism 5 to move axially at high speed and form a circulation. During the circulation, the gas passes through the interlayer between the stator mechanism 2 and the housing mechanism 1 and comes into contact with the heat-conducting boss mechanism 3 and the heat pipe assembly 108. The heat in the gas will be carried by the heat-conducting boss mechanism 3 and the heat pipe assembly 108 to the first heat dissipation fin 104 and dissipated outward, thereby efficiently dissipating heat in the center of the stator. At the same time, the cover mechanism 6 and the reduction mechanism 7 can also absorb and conduct heat, further improving the heat dissipation effect of the device.
