Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, and in particular to an eddy current power drive speed reducer. Background Technology

[0002] Currently, with the global promotion and popularization of the Industry 4.0 concept, the requirements for automation equipment in various industries are constantly increasing, especially the need to ensure operational stability while improving production efficiency. Traditional speed reducers, as a key component in achieving this goal, face numerous challenges in practical applications. The mainstream speed reducers on the market today include gear reducers and worm gear reducers, among others. Gear reducers are widely used due to their high transmission efficiency, but problems such as increased wear and shortened service life caused by poor tooth surface contact still plague many manufacturers. While worm gear reducers have a self-locking function to ensure safety, their limited transmission ratio makes them difficult to meet the needs of certain specific applications. Furthermore, a few manufacturers have begun to try using hydraulic couplings to replace traditional mechanical connections to reduce vibration and noise. Although this can alleviate excessive impact loads to some extent, it fails to fundamentally solve the core problems of reliability and high maintenance costs under long-term service conditions.

[0003] In the process of realizing this utility model, the inventors discovered that the technology has at least the following problems: the existing speed reducer technology generally has shortcomings such as high energy consumption, obvious operating noise and poor adaptability to harsh environments. These limitations restrict their competitiveness and development potential in the high-end market. Therefore, the eddy current power drive speed reducer is now proposed. Utility Model Content

[0004] In order to improve the shortcomings of speed reducers, such as high energy consumption, significant operating noise, and poor adaptability to harsh environments, this utility model provides an eddy current power drive speed reducer.

[0005] This utility model provides an eddy current power drive reducer, which adopts the following technical solution:

[0006] An eddy current power drive reducer includes a housing, a cover plate detachably connected to the upper outer surface of the housing, a drive motor fixedly connected to the rear outer surface of the housing, a rotor shaft penetrating the front outer surface of the housing, a base fixedly connected to the upper outer surface of the housing, and an eddy current power drive mechanism disposed in the inner cavity of the housing.

[0007] The eddy current power drive mechanism includes a sealed bearing, a sealing plate, a rotating wheel, rotating wheel blades, a precision ball bearing, an eddy current channel, a partition, an air pipe connection joint, an air pipe connection threaded cap, an air pipe, a filter screen and an external thread. The sealed bearing is fixedly connected to the outer wall of the rotor shaft.

[0008] By adopting the above technical solution and setting the sealed bearing, the sealing performance between the sealed bearing and the housing can be improved, so that an annular sealed space is formed between the sealed bearing and the housing, which is more conducive to the flow of air in the inner cavity of the housing.

[0009] Optionally, a sealing plate is fixedly connected to the outer wall of the sealed bearing, a rotating wheel is fixedly connected to the outer wall of the rotor shaft, and rotating wheel blades are fixedly connected to the outer wall of the rotating wheel. The number of the sealed bearing, sealing plate, and rotating wheel are all two sets, and the number of rotating wheel blades is several sets.

[0010] By adopting the above technical solution, and through the arrangement of the rotating wheel and its blades, when it is necessary to reduce the speed of the rotor shaft, flowing gas is injected into the inner cavity of the outer casing. Under the flow of the gas, the rotating wheel and its blades rotate in opposite directions. Driven by external force, the rotating wheel and its blades rotate to form a strong vortex. The pressure at the center of the vortex is much lower than that in the surrounding area, thus generating a significant pressure gradient that drives the gas flow. At the same time, the fluid particles collide and compress with each other to form a continuous turbulent field. This dynamic equilibrium state maintains a high kinetic energy conversion rate until the predetermined torque value is reached and the rotation stops. Furthermore, each blade is forged from high-strength aluminum alloy and undergoes surface oxidation treatment to improve wear and corrosion resistance, making it lightweight and high-strength.

[0011] Optionally, precision ball bearings are fixedly connected to the outer surfaces of the front and rear ends of the housing, and the precision ball bearings are fixedly connected to the rotor shaft.

[0012] By adopting the above technical solution and using precision ball bearings, we can easily install the rotor shaft on the housing. At the same time, precision ball bearings can maintain a low coefficient of friction while withstanding large radial loads.

[0013] Optionally, the outer shell and the sealing plate are fixedly connected, the space sealed by the outer shell and the two sets of sealing plates is a vortex channel, a partition is fixedly connected in the inner cavity of the outer shell, and the partition is located on one side of the sealing plate, and the number of partitions is several sets.

[0014] By adopting the above technical solution and setting up baffles, the turbulence effect of the vortex channel can be increased. The baffle material is made of special engineering plastic, which is not only lightweight but also high in strength.

[0015] Optionally, an air pipe connector is fixedly connected to the upper outer surface of the cover plate. The air pipe connector is connected to the inner cavity of the outer shell. The inlet of the air pipe connector is located in the middle of the two sets of rotating wheels. An air pipe connecting threaded cap is detachably connected to the upper outer surface of the air pipe connector. An air pipe is movably connected to the upper outer surface of the air pipe connecting threaded cap.

[0016] By adopting the above technical solution and using the threaded cap for the air tube connection, we can easily and quickly install or remove the air tube from the air tube connection joint.

[0017] Optionally, a filter screen is provided between the tracheal connector and the tracheal connector threaded cap, and the outer wall of the tracheal connector is provided with external threads.

[0018] By adopting the above technical solution and setting up a filter screen, some impurities in the gas can be filtered out when the gas is injected into the interior, and the filter screen can be disassembled for cleaning and replacement.

[0019] In summary, this utility model has the following beneficial effects:

[0020] This invention utilizes an eddy current power drive mechanism. When the rotor shaft needs to decelerate, flowing gas is injected into the annular sealed space between the two sets of sealing plates and the outer shell. The gas flow drives the rotating wheel and its blades to rotate, creating a strong vortex. The pressure at the center of the vortex is much lower than in the surrounding area, resulting in a significant pressure gradient that drives the gas flow. Simultaneously, the collision and compression of fluid particles create a continuous turbulent field. This dynamic equilibrium maintains a high kinetic energy conversion rate until a predetermined torque value is reached and rotation stops. This invention improves the overall performance of the reducer by injecting flowing gas, particularly addressing key technical challenges such as enhanced transmission smoothness, reduced energy loss, and improved anti-interference stability. It improves the overall efficiency of the transmission system, maintaining good responsiveness and positioning accuracy even under heavy loads. This reduces total energy consumption and effectively controls emissions, contributing to a greener and more environmentally friendly manufacturing ecosystem. Furthermore, it simplifies daily maintenance procedures, facilitating on-site troubleshooting and repair by frontline personnel, extending the equipment's lifespan, and indirectly saving subsequent investment funds.

The sealed bearing 601 is fixedly connected to the outer wall of the rotor shaft 4. The sealing bearing 601 improves the sealing performance between the sealed bearing 601 and the housing 1, forming an annular sealed space between the sealed bearing 601 and the housing 1, which is more conducive to the flow of air in the inner cavity of the housing 1.

Through the arrangement of the rotating wheel 603 and rotating wheel blades 604, when it is necessary to reduce the speed of the rotor shaft 4, flowing gas is injected into the inner cavity of the outer casing 1. Under the flow of gas, the rotating wheel 603 and rotating wheel blades 604 are driven. Rotating in the opposite direction, the rotating wheel 603 and rotating wheel blade 604 rotate under the drive of external force to form a strong vortex. The pressure at the center of the vortex is much lower than that in the surrounding area, thus generating a significant pressure gradient that drives the gas flow. At the same time, the fluid particles collide and compress with each other to form a continuous turbulent field. Relying on this dynamic equilibrium state, a high-efficiency kinetic energy conversion rate is maintained until the predetermined torque value is reached, until the rotation stops. Each rotating wheel blade 604 is forged from high-strength aluminum alloy and undergoes surface oxidation treatment to improve wear resistance and corrosion resistance. It is lightweight and has high strength.

At the same time, the precision ball bearings 605 can maintain a low coefficient of friction while bearing a large radial load. The outer casing 1 is fixedly connected to the sealing plate 602. The space sealed by the outer casing 1 and the two sets of sealing plates 602 is a vortex channel 606. A partition plate 607 is fixedly connected in the inner cavity of the outer casing 1. The partition plate 607 is located on one side of the sealing plate 602, and there are several sets of partition plates 607. The setting of the partition plate 607 can increase the turbulence effect of the vortex channel 606, guide the gas to flow towards the center of the rotor shaft 4 to form a vortex, and the material of the partition plate 607 is made of special engineering plastic, which is not only lightweight but also high in strength.

The air pipe connector 608 is connected to the inner cavity of the outer shell 1. The inlet of the air pipe connector 608 is located in the middle of the two sets of rotating wheels 603. An air pipe thread cap 609 is detachably connected to the upper outer surface of the air pipe connector 608. An air pipe 610 is movably connected to the upper outer surface of the air pipe thread cap 609. The air pipe thread cap 609 allows for easy and quick installation or removal of the air pipe 610 from the air pipe connector 608. A filter screen 611 is provided between the air pipe connector 608 and the air pipe thread cap 609. The outer wall of the air pipe connector 608 is provided with an external thread 612. The filter screen 611 can filter out some impurities in the gas when it is injected into the interior. The filter screen 611 can be removed for cleaning and replacement, which can effectively avoid the risk of blockage caused by the vortex channel 606.

[0033] The implementation principle of this utility model is as follows: In the eddy current power drive reducer, when the rotor shaft 4 needs to be reduced in speed, flowing gas is injected into the annular sealed space between the two sets of sealing plates 602 and the outer shell 1 via the eddy current power drive mechanism 6. Under the flow of gas, the rotating wheel 603 and the rotating wheel blades 604 are driven to rotate. The rotation of the rotating wheel 603 and the rotating wheel blades 604 creates a strong vortex. The pressure at the center of the vortex is much lower than that in the surrounding area, thus generating a significant pressure gradient that drives the gas flow. Simultaneously, the fluid particles collide and compress with each other, forming a continuous turbulent field. This dynamic equilibrium state maintains a high kinetic energy conversion rate until the predetermined torque value is reached and rotation stops. Therefore, the overall performance of the reducer is improved by injecting flowing gas. Breakthroughs have been made in key technologies, particularly in improving transmission smoothness, reducing energy loss, and enhancing anti-interference stability. This has improved the overall performance of the transmission system, especially in maintaining good responsiveness and positioning accuracy under heavy load conditions. It has reduced total energy consumption and effectively controlled emissions, contributing to a greener and more environmentally friendly manufacturing ecosystem. At the same time, it simplifies daily maintenance procedures, facilitating on-site troubleshooting and repair by frontline personnel, extending the equipment's lifespan and indirectly saving subsequent investment funds. Furthermore, the filter screen 611 can filter out some impurities in the gas when it is injected, and the filter screen 611 can be disassembled for cleaning and replacement, effectively avoiding the risk of blockage caused by the eddy current channel 606.
