Description

Technical Field

[0002] This invention belongs to the technical field of mechanical speed reduction transmission equipment, specifically relating to an energy-saving lever reducer that employs a four-dimensional spatial layout, multi-stage linkage, four-dimensional linkage direct drive, stepped off-peak time-sharing drive, vacuum drag reduction, outer edge lever torque increase, and large disc wear-resistant protection. This invention can be widely applied to heavy engineering machinery, large fans, large water pumps, industrial conveying equipment, mining equipment, large agricultural machinery, and automated complete sets of equipment, adaptable to transmission conditions requiring low-speed, high-torque output, continuous all-weather operation, and ultra-large-scale assembly. Background Technology

[0003] Currently, mainstream reducers in the industrial field are divided into several categories: gear meshing transmission, worm gear transmission, and planetary gear transmission. These devices rely on rigid contact surface compression, tooth surface meshing, and sliding friction to transmit power, which has many inherent defects: high mechanical friction loss, high heat generation during operation, high operating noise, rapid tooth surface wear, limited service life, and high frequency of routine maintenance. Conventional reducer housings have an open ventilation structure, and the swing arm and turntable continuously agitate the internal air during operation, generating a large amount of wind resistance and airflow turbulence, resulting in additional power consumption. The output discs used in large, heavy-duty equipment are mostly made of solid steel, which is heavy and has strong rotational inertia, making it prone to deformation after heating, and making it difficult to ensure the coaxiality of the equipment. If lightweight composite materials are used to make the disc surface, the outer side of the disc surface lacks a dedicated wear-resistant protective structure, and under long-term friction and impact from the push bearing, it is very easy for the surface layer to peel off and the disc surface to wear and break. At the same time, traditional equipment generally adopts a synchronous power drive mode, which concentrates the load at the force points, accelerating the wear and aging of components. Currently, there is no complete transmission technology in the industry that combines four-stage linkage with multi-stage linkage of swing arms, four-dimensional multi-directional layout, staggered peak driving, vacuum drag reduction, lever torque increase, and wear-resistant protection of large discs. There is a significant technological gap in this field. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by proposing a novel and optimized solution.

[0005] Purpose of the invention This invention aims to solve the problems of high frictional energy consumption, large wind resistance loss, concentrated force impact, easy deformation and wear of the large disc, short service life, limited torque increase, and insufficient operational stability of traditional reducers. It provides a four-dimensional linkage stepped multi-stage series energy-saving lever reducer, which achieves low transmission loss, energy saving and consumption reduction, large torque output, stable and reliable operation, long service life, and customizable specifications and dimensions. Technical solution

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a four-dimensional linkage stepped multi-stage series energy-saving lever reducer, comprising a housing assembly, a power input mechanism, a four-dimensional multi-stage linkage transmission mechanism, a swing positioning mechanism, a lever drive mechanism, a reset mechanism, and a power output mechanism. The power input mechanism is installed inside the housing. The input shaft is positioned and rotated by the housing support bearing. The input shaft is fixed with an eccentric cam component, converting continuous rotational power into periodic reciprocating swing power. The four-dimensional multi-stage linkage transmission mechanism adopts a four-dimensional spatial multi-directional three-dimensional layout, using four-dimensional linkage direct push as the core transmission method. The transmission direction and number of transmission groups can be adjusted according to the equipment load. A single transmission unit consists of a first-stage linkage, a second-stage linkage, a third-stage linkage, a fourth-stage linkage, and a swing arm connected in series in a hinged manner, forming a multi-stage linkage system. Power transmission is smooth, and equipment adaptability is strong. The working phases of each multi-stage linkage transmission unit are staggered, preventing synchronous pushing work. The output disc is pushed in a stepped manner according to a preset timing sequence, outputting continuous, stable, and low-impact rotary power. The swing positioning mechanism constrains the motion trajectory of each connecting rod and swing arm, ensuring precise swing angles and stable operation, and avoiding faults such as transmission jamming, positional deviation, and transmission misalignment. The lever drive mechanism is located at the end of the swing arm, relying on the wear-resistant ring on the outer edge of the output disc via the push bearing, and uses the lever structure to complete the push torque amplification operation. The reset mechanism connects the housing at one end and the swing transmission component at the other, only responsible for the reset action of the connecting rod and swing arm assembly, and has no structural connection with the output rotating component; after a single push operation, the component automatically springs back to its original position, ready for the next cycle of push. The power output mechanism amplifies the output torque using the lever arm formed by the force applied to the outer edge and the rotation of the center; the radial bearing on the outer circumference of the output disc, combined with the upper and lower limit bearings of the main shaft, ensures the coaxiality of the equipment in all directions, preventing wobbling and deviation during operation. The housing is completely sealed and internal air is extracted to form a vacuum chamber, eliminating the ineffective energy consumption caused by wind resistance and air friction. The output disc is made of carbon fiber to achieve a lightweight design. The disc surface is reinforced with plates on both sides, and an aluminum alloy honeycomb support frame is laid inside. The outer edge is covered with a rigid and wear-resistant protective ring. The equipment can produce ultra-large discs with diameters from 1 meter to 15 meters, while effectively solving the problem of disc surface wear caused by outer edge pushing.

Low transmission loss and excellent energy-saving effect. By abandoning the hard friction of gears and the sliding friction of worm gears, and combining it with a vacuum-free, wind-resistant cavity design, ineffective power loss is significantly reduced, and energy-saving performance far exceeds that of traditional speed reduction equipment.

[0008] 2. Excellent torque amplification performance By utilizing the lever principle of the outer edge of the output panel, a small power input can be converted into a large torque output, which can meet the needs of various heavy-duty equipment.

[0009] 3. Smooth operation with minimal impact and vibration. Multiple transmission units work alternately during off-peak hours, resulting in evenly distributed loads, minimal equipment vibration, and low operating noise.

[0010] 4. The disc body is lightweight and has high strength, making it resistant to deformation. The carbon fiber composite material combined with the aluminum alloy honeycomb frame is lightweight, structurally rigid, and has a small amount of thermal deformation, making it suitable for manufacturing large transmission discs up to ten meters in length.

[0011] 5. Long equipment lifespan and low maintenance frequency An independent external rigid wear-resistant ring withstands all friction and impact, protecting the carbon fiber disc from damage, significantly extending the overall service life of the equipment, and reducing maintenance costs.

[0012] 6. Broad patent protection coverage Under the same transmission principle, the equivalent structure obtained by changing the number of components, layout, and manufacturing materials is protected by patents and has strong resistance to imitation.

[0014] A four-dimensional linkage stepped multi-stage series energy-saving lever reducer includes a housing assembly, a power input mechanism, a four-dimensional multi-stage linkage transmission mechanism, a swing positioning mechanism, a lever drive mechanism, a reset mechanism, and a power output mechanism. The housing assembly uses a high-strength, pressure-resistant, sealed housing. After assembly, internal air is extracted to form an airless, sealed cavity, completely eliminating power loss caused by wind resistance. The power input mechanism consists of an input shaft and an eccentric cam. The eccentric cam rotates synchronously with the input shaft, continuously driving each group of first-stage linkages to perform reciprocating swing motion. The entire machine adopts a four-dimensional spatial layout, with multi-stage linkage transmission units independently arranged in multiple directions. Within each group, first-stage, second-stage, third-stage, and fourth-stage linkages are sequentially connected in series, with the ends of the linkages hinged to a swing arm to form a complete linkage mechanism. In actual production, the number of linkage stages and transmission groups can be adjusted according to the load size. The operating phases of each transmission unit are staggered, sequentially completing the pushing action, forming a stepped relay transmission to ensure continuous power output. One end of the swing positioning linkage is fixed to the inner wall of the housing, and the other end is hinged to the side of the linkage or swing arm, precisely constraining the swing trajectory of the components and ensuring stable and reliable transmission accuracy. The end of the swing arm is fixedly installed with a drive swing arm and a push bearing. The push bearing is fitted against the surface of the rigid wear-resistant protective ring on the outer edge of the output disc, driving the output disc to rotate in a time-sharing manner. One end of the return spring is fixed to the housing, and the other end is connected to the swing arm transmission assembly. After a single push, it pulls the entire swing component back to its original position, enabling cyclic operation. The return mechanism has no structural connection to the output disc or output shaft, ensuring independent and stable operation of the rotating components. The output disc has an internal aluminum alloy honeycomb support frame, with the main body made of carbon fiber composite material, reinforced on both sides, and the outer edge is entirely covered with a rigid wear-resistant protective ring. Multiple sets of radial support bearings are arranged around the outer perimeter of the output disc, and limit bearings are installed at the upper and lower ends of the output shaft, ensuring no offset or shaking during equipment operation and that coaxiality meets operational requirements. The output disc can be customized to different diameter specifications from 1 meter to 15 meters according to usage requirements, adapting to low-speed, high-torque transmission conditions of various ultra-large heavy industrial equipment. This embodiment preferably features a four-dimensional, four-directional layout, four-stage linkage series connection, multiple sets of staggered peak pushing, vacuum drag reduction, and wear-resistant outer edge protection. Any structure based on the core principles of this invention that undergoes equivalent structural modifications, increases or decreases in the number of linkage stages, adjusts the number of transmission groups, fine-tunes the layout, or replaces materials falls within the scope of protection of this invention.
