Description

Technical Field

[0001] This invention relates to the field of electric motors, and in particular to a high-efficiency and energy-saving electric motor. Background Technology

[0002] High-efficiency energy-saving motors are electric motors that significantly reduce electromagnetic, thermal, and mechanical energy losses and improve energy conversion efficiency through optimized design, materials, and processes.

[0003] Currently, when the motor is running, a bearing can be installed between the spindle and the housing to reduce friction between the spindle and the housing, thereby reducing energy consumption. However, the lateral stress received by the bearing varies during different uses, which may lead to bearing misalignment and increased friction. In addition, bearings generally require regular lubrication. When the bearing lacks maintenance, its friction will also increase, thereby increasing energy consumption and heat generation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a high-efficiency and energy-saving motor. It overcomes these shortcomings by addressing the issue that while bearings can be installed between the main shaft and the housing during motor operation to reduce friction and save energy, the bearings experience varying lateral stresses during different usage periods, which may lead to misalignment and increased friction. Furthermore, bearings typically require regular lubrication; lack of maintenance further increases friction, thus increasing energy consumption and heat generation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency energy-saving motor, comprising a housing and a running mechanism disposed inside the housing, wherein the running mechanism is provided with a main shaft passing through the inner walls of both ends of the housing;

[0006] A rotating mechanism is located on both sides of the operating mechanism, including two sets of bearings sleeved and installed on the outer wall of the main shaft. Two positioning rings are fixedly installed on the outer wall of the main shaft between the two sets of bearings. A set of blades is welded to the outer wall of each positioning ring. A corresponding outer ring is welded to the outer wall of each set of blades on the side away from the positioning ring. Multiple sets of movable grooves are opened on the outer wall of the outer ring. I-shaped wheels are rotatably installed on the inner wall of the outer ring inside the corresponding movable grooves. A track is embedded in the groove end of the I-shaped wheel.

[0007] The lubrication mechanism includes a main channel disposed in the inner wall of the main shaft, and sub-channels are respectively disposed between the main shaft, bearing, positioning ring, blade and outer ring.

[0008] By adopting the above technical solution, during use, by setting a positioning ring and blades on the outer wall of the main shaft, and rotating and installing the I-shaped wheel in the movable groove of the outer ring of the blade and embedding it into the track, the lateral stress on the bearing can be effectively dispersed, avoiding bearing misalignment and reducing the problem of increased friction caused by misalignment. At the same time, a lubrication mechanism is set up, and the main channel on the inner wall of the main shaft is connected to the sub-channels between various components. When the main shaft rotates, under the centrifugal cooperation, it can continuously provide lubrication for the bearings, I-shaped wheels, etc., reducing the increase in friction caused by lack of maintenance, thereby reducing mechanical energy loss, reducing heat generation, and achieving energy saving and consumption reduction.

[0009] As a preferred embodiment of the present invention, the housing includes a middle cylinder, with end caps fixedly installed at both ends of the middle cylinder, and multiple sets of heat dissipation fins welded to the outer wall of the middle cylinder.

[0010] By adopting the above technical solution, the middle cylinder can be used to fix and install the end caps on both sides and the external heat dissipation fins, and the heat dissipation fins can dissipate heat from inside the middle cylinder.

[0011] In a preferred embodiment of the present invention, a U-shaped frame is fixedly installed on the outer wall of one of the end caps, a rotary joint is installed on the outer wall of the tail end of the main shaft, and an inlet pipe is installed on the end of the rotary joint away from the main shaft, and the inlet pipe slides through the U-shaped frame.

[0012] By adopting the above technical solution, the end cap can fix the U-shaped frame, the rotary joint can rotate the inlet pipe and the main shaft, and the U-shaped frame can position and fix the inlet pipe, thus facilitating the external oil supply mechanism to periodically add lubricating oil to the inside of the inlet pipe.

[0013] As a preferred embodiment of the present invention, the outer walls of the two end caps are respectively provided with vent holes, and the inner walls of the end caps located inside the vent holes are respectively equipped with annular filters.

[0014] By adopting the above technical solution, the air vents can be used to unblock the airflow, and the annular filter can filter the airflow that is unblocked in the air vents.

[0015] As a preferred embodiment of the present invention, a rotor is sleeved on the outer wall of the main shaft, and a stator is embedded in the inner wall of the middle cylinder, with the stator sleeved on the outside of the rotor.

[0016] By adopting the above technical solution, the middle cylinder can fix the rotor, and the cooperation between the rotor and the stator can facilitate the rotation of the main shaft.

[0017] As a preferred embodiment of the present invention, the outer walls of the two sets of tracks are fixedly installed with the inner walls of the corresponding end caps, and the two sets of bearings are respectively embedded in the inner walls of the corresponding end caps.

[0018] By adopting the above technical solution, the corresponding end caps can respectively fix the track and the bearing.

[0019] As a preferred embodiment of the present invention, the sub-channel located inside the bearing extends to the inner ring wall of the bearing, and the sub-channel located on one side of the I-shaped wheel extends through the positioning ring, the blade and the outer ring to the I-shaped wheel at the movable groove end.

[0020] By adopting the above technical solution, the different component channels can facilitate the entry of lubricating oil into the bearing interior and the outer wall of the I-shaped wheel, thereby lubricating the balls inside the bearing and the outer wall of the I-shaped wheel and reducing the friction during operation.

[0021] As a preferred embodiment of the present invention, both sets of blades are arranged at an inclined angle, and the inclination angles of the two sets of blades are the same.

[0022] By adopting the above technical solution, the blades are tilted at the same angle, which facilitates the effective transport of airflow when the two sets of blades rotate, and the airflow passes through the operating mechanism, which facilitates the removal of heat from the operating mechanism.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. This invention, by setting a positioning ring and blades on the outer wall of the main shaft, and rotatably installing I-shaped wheels in the movable groove of the outer ring of the blades and embedding them in the track, can effectively disperse the lateral stress on the bearing, avoid bearing misalignment, and reduce the problem of increased friction caused by misalignment; at the same time, a lubrication mechanism is set up, and the main channel on the inner wall of the main shaft is connected to the sub-channels between various components.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-6 A high-efficiency energy-saving motor includes a housing 1 and a running mechanism 2 disposed inside the housing 1. The running mechanism 2 has a main shaft 201 passing through the inner walls of both ends of the housing 1. A rotating mechanism 3 is disposed on both sides of the running mechanism 2, including two sets of bearings 301 sleeved and installed on the outer wall of the main shaft 201. Two positioning rings 303 are fixedly installed on the outer wall of the main shaft 201 between the two sets of bearings 301. A set of blades 304 are welded to the outer wall of each of the two positioning rings 303. Each set of blades 304 is positioned at... A corresponding outer ring 305 is welded to the outer wall on the side away from the positioning ring 303. Multiple sets of movable grooves 306 are opened on the outer wall of the outer ring 305. I-shaped wheels 307 are rotatably installed on the inner wall of the outer ring 305 located inside the corresponding movable grooves 306. The groove end of the I-shaped wheel 307 is embedded with a track 302. The lubrication mechanism 4 includes a main channel 402 set in the inner wall of the main shaft 201. Sub-channels 403 are respectively set between the main shaft 201, bearing 301, positioning ring 303, blade 304 and outer ring 305.

[0036] By setting a positioning ring 303 and a blade 304 on the outer wall of the main shaft 201, and rotatably installing a I-shaped wheel 307 in the movable groove 306 of the outer ring 305 of the blade 304 and embedding it into the track 302, the lateral stress on the bearing 301 can be effectively dispersed, avoiding misalignment of the bearing 301 and reducing the problem of increased friction caused by misalignment. At the same time, a lubrication mechanism 4 is set up, with the main channel 402 on the inner wall of the main shaft 201 connected to the sub-channels 403 between various components. When the main shaft 201 rotates, under the centrifugal cooperation, it can continuously provide lubrication for the bearing 301, the I-shaped wheel 307, etc., reducing the increase in friction caused by lack of maintenance, thereby reducing mechanical energy loss, reducing heat generation, and achieving energy saving and consumption reduction.

[0037] For details, please refer to Figure 1 The housing 1 includes a middle cylinder 101, with end caps 102 fixedly installed at both ends of the middle cylinder 101. Multiple sets of heat dissipation fins 103 are welded to the outer wall of the middle cylinder 101. The middle cylinder 101 can fix the end caps 102 on both sides and the external heat dissipation fins 103. The heat dissipation fins 103 can dissipate heat from the inside of the middle cylinder 101.

[0038] For details, please refer to Figure 1 and Figure 2 The outer wall of the main shaft 201 is fitted with a rotor 203, and the inner wall of the middle cylinder 101 is fitted with a stator 202. The stator 202 is fitted on the outside of the rotor 203. The middle cylinder 101 can fix the rotor 203. The rotor 203 and the stator 202 cooperate to facilitate the rotation of the main shaft 201. The outer walls of the two sets of rails 302 are fixedly installed with the inner walls of the corresponding end caps 102, and the two sets of bearings 301 are embedded in the inner walls of the corresponding end caps 102. The corresponding end caps 102 can fix the rails 302 and the bearings 301 respectively.

[0039] For details, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 Both sets of blades 304 are set at an inclined angle, and the two sets of blades 304 are inclined at the same angle. By having the blades 304 inclined at the same angle, it is convenient for the two sets of blades 304 to drive the airflow effectively when rotating, and the airflow passes through the operating mechanism 2, which facilitates the removal of heat from the operating mechanism 2. The outer walls of the two end caps 102 are respectively provided with vent holes 6, and the inner walls of the end caps 102 located inside the vent holes 6 are respectively installed with annular filters 7. The vent holes 6 can play a role in unblocking the airflow, and the annular filters 7 can play a role in filtering the airflow unblocked in the vent holes 6.

[0040] For details, please refer to Figures 1-3One of the end caps 102 has a U-shaped bracket 5 fixedly installed on its outer wall, and a rotary joint 401 is installed on the outer wall of the tail end of the main shaft 201. An inlet pipe 404 is installed at the end of the rotary joint 401 away from the main shaft 201. The inlet pipe 404 slides through the U-shaped bracket 5. The end cap 102 can fix the U-shaped bracket 5, while the rotary joint 401 can rotatably connect the inlet pipe 404 and the main shaft 201. The U-shaped bracket 5 can position and fix the inlet pipe 404, thus facilitating the connection of an external oil supply mechanism to the inlet pipe 404. The internal part of the 04 section serves to periodically add lubricating oil. The sub-channel 403 located inside the bearing 301 extends to the inner ring wall of the bearing 301. The sub-channel 403 located on one side of the I-shaped wheel 307 passes through the positioning ring 303, the blade 304, and the outer ring 305 and extends to the I-shaped wheel 307 at the end of the movable groove 306. The arrangement of different component channels 403 facilitates the entry of lubricating oil into the interior of the bearing 301 and the outer wall of the I-shaped wheel 307, which facilitates the lubrication of the balls inside the bearing 301 and the outer wall of the I-shaped wheel 307, reducing the friction during operation.

[0041] Working principle: During use, the main shaft 201 rotates under the drive of the operating mechanism 2, causing the two positioning rings 303 fixed to its outer wall to rotate synchronously. The two sets of blades 304 with the same inclination angle on the positioning rings 303 rotate accordingly. Because the blades 304 are set at a specific inclination angle, they will form a directional airflow when rotating, allowing the airflow to pass through the entire operating mechanism 2 and carry away the heat generated during operation, thus playing a heat dissipation role. At the same time, the I-shaped wheel 307 in the movable groove 306 of the outer ring 305 of the blade 304 is embedded in the track 302 fixed to the inner wall of the end cover 102. When the blades 304 rotate, the I-shaped wheel 307... 07 Rolls along track 302, which can effectively disperse the lateral stress on bearing 301 and prevent bearing 301 from being misaligned; the main channel 402 on the inner wall of the main shaft 201 is connected to the sub-channels 403 between various components. The centrifugal force generated by the rotation of the main shaft 201 causes lubricating oil to enter the inner ring wall of bearing 301 through the main channel 402 and sub-channels 403, and to reach the I-shaped wheel 307 at the end of the movable groove 306 through the positioning ring 303, blade 304, and outer ring 305, providing continuous lubrication for the bearing 301 balls and the outer wall of the I-shaped wheel 307, reducing friction, reducing mechanical energy loss and heat generation, and achieving energy-saving and efficient operation.
