Description

Technical Field

[0001] This utility model relates to the field of heavy-duty gear assembly technology, specifically to a heavy-duty gear assembly for mixer trucks. Background Technology

[0002] Heavy-duty gear assemblies for concrete mixer trucks are key components in the transmission system of concrete mixer trucks, playing a vital role in transmitting torque and supporting the working load of the concrete mixer truck.

[0003] Traditional gear assemblies for concrete mixer trucks rely primarily on gear-driven oil splash lubrication and oil sump cooling under heavy loads. Under high loads and prolonged operation, heat accumulates rapidly, oil temperatures rise, lubrication efficiency decreases, and galling failure easily occurs, thus affecting the service life of the gear assembly and the overall performance of the concrete mixer truck. Therefore, we propose a heavy-duty gear assembly for concrete mixer trucks. Utility Model Content

[0004] The purpose of this invention is to address the problem that traditional gear assemblies for concrete mixer trucks rely primarily on gear-driven oil splash lubrication and oil sump cooling under heavy loads. Under high loads and prolonged operation, heat accumulates rapidly, oil temperature rises, lubrication efficiency decreases, and galling failure easily occurs, thus affecting the service life of the gear assembly and the overall performance of the concrete mixer truck. This invention provides a heavy-duty gear assembly for concrete mixer trucks.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution: A heavy-duty gear assembly for a mixer truck includes a main housing. A transmission gear set, meshing with each other, is rotatably mounted inside the main housing via a gear shaft. An upper cover is bolted to the upper end of the main housing. The upper inner wall of the upper cover has corresponding arc-shaped concave surfaces on both sides, with an oil guide tip formed at the center of the two arc-shaped concave surfaces. A heat dissipation oil reservoir is fixedly connected to the center of the inner walls on both sides of the upper cover, and the heat dissipation oil reservoir is located directly below the oil guide tip. An oil drip port is provided at the bottom of the heat dissipation oil reservoir corresponding to the meshing position of the transmission gear set. A heat pipe cooling mechanism is provided on both sides of the upper cover corresponding to the heat dissipation oil reservoir.

[0006] Furthermore, the heat pipe heat dissipation mechanism includes multiple heat pipe radiators, each of which is an L-shaped heat pipe. The multiple heat pipe radiators are evenly distributed on both sides of the heat dissipation oil reservoir. The bottom of the heat pipe radiator is bent towards the center of the heat dissipation oil reservoir to form an L-shape. Multiple heat dissipation fins are evenly distributed and fixed on the upper end of the upper shell cover. The multiple heat pipe radiators on both sides are embedded in the heat dissipation fins at the corresponding positions after penetrating the upper shell cover.

[0007] Furthermore, filter screens are fixedly connected to both sides of the bottom of the heat dissipation oil storage tank corresponding to the oil drip port.

[0008] Furthermore, multiple iron filings adsorption magnets are provided on the upper side of the bottom of the heat dissipation oil storage tank, corresponding to the outer side of the filter screen, and the multiple iron filings adsorption magnets are arranged at equal intervals.

[0009] Furthermore, a fixed top plate is fixedly connected to the upper end of multiple iron filings adsorption magnets on the same side, and a filings hanging sleeve is movably sleeved on the multiple iron filings adsorption magnets. A limiting horizontal plate is provided on the upper side of the filings hanging sleeve, and an operating lever is fixedly connected to the upper end of the fixed top plate corresponding to the position of the limiting horizontal plate. The upper end of the operating lever passes through the limiting horizontal plate and is connected to a horizontal handle.

[0010] Furthermore, a return spring is fixedly connected between the bottom two sides of the limiting horizontal plate and the chip hanging sleeve plate.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model transmits torque through the operation of a transmission gear set. When the transmission gear set rotates, it carries lubricating oil, which, under the centrifugal force of the gear set, slides along the arc-shaped concave surfaces corresponding to the upper sides of the inner wall of the upper shell. Guided by the oil guide tip, the oil falls into the heat dissipation oil reservoir, and then drips through the oil drip nozzle to the meshing position of the transmission gear set, thus lubricating the gears. Simultaneously, the heat pipe cooling mechanism operates, dissipating the heat generated by the heat dissipation oil reservoir and the transmission gear set into the air through the heat dissipation fins, achieving efficient heat dissipation and preventing damage to the heavy-duty gear assembly due to overheating, thereby extending its service life. Furthermore, the robust design of the main shell and the precise fit of each component ensure the stability and reliability of the heavy-duty gear assembly during the operation of the mixer truck, improving the working efficiency of the mixer truck.

[0012] 2. This utility model uses a heat pipe radiator to quickly remove heat from the heat storage tank and then dissipates the heat into the air through heat dissipation fins, which effectively improves heat dissipation efficiency and avoids the problem of reduced lubrication efficiency and adhesion failure of heavy-duty gear components due to excessively high oil temperature. This further extends the service life of the gear components and improves the overall performance and stability of the mixer truck.

[0013] 3. This utility model features a fixed top plate that connects and fixes multiple iron filings adsorbing magnets. Lubricating oil passes through the gaps between these magnets, attracting the iron filings in the oil onto the magnets. Simultaneously, the inclusion of a scraper plate allows for quick iron filings removal. Pulling the operating rod upwards moves the top plate, causing the scraper plate to scrape off the iron filings adsorbed on the outer wall of the magnets, preventing iron filings from accumulating and affecting the magnets' adsorption effect. This further improves the lubrication and operational stability of the gear assembly. Furthermore, the operating rod and horizontal handle make iron filings removal more convenient and labor-saving, increasing work efficiency. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0017] Please see Figure 1 - Figure 3 This utility model provides a heavy-duty gear assembly for a mixer truck, including a main housing 1. The inner cavity of the main housing 1 is rotatably equipped with a transmission gear set 2 that meshes with each other via a gear shaft. The upper end of the main housing 1 is fixedly connected to an upper cover 3 by bolts. The upper wall of the upper cover 3 has arc-shaped concave surfaces on both sides, and the center of the arc-shaped concave surfaces on both sides forms an oil guide tip 5. The center of the inner wall on both sides of the upper cover 3 is fixedly connected to a heat dissipation oil storage tank 4, and the heat dissipation oil storage tank 4 is located directly below the oil guide tip 5. The bottom of the heat dissipation oil storage tank 4 has an oil drip port 6 corresponding to the meshing position of the transmission gear set 2. The upper cover 3 is provided with a heat pipe heat dissipation mechanism on both sides corresponding to the heat dissipation oil storage tank 4.

[0018] The working principle and usage process of this utility model are as follows: During use, torque is transmitted through the operation of the transmission gear set 2. When the transmission gear set 2 operates, it carries the lubricating oil, causing the lubricating oil to slide along the arc-shaped concave surfaces corresponding to the upper sides of the inner wall of the upper shell cover 3 under the centrifugal force of the transmission gear set 2. Then, guided by the oil guide tip 5, the oil falls into the heat dissipation oil storage tank 4, and then drips through the oil dripping port 6 to the meshing position of the transmission gear set 2, thus lubricating the gears. At the same time, the heat pipe cooling mechanism works to conduct the heat generated by the heat dissipation oil storage tank 4 and the transmission gear set 2, and dissipates it into the air through the heat dissipation fins 10, achieving efficient heat dissipation and preventing damage to the heavy-duty gear assembly due to overheating, thus extending its service life. In addition, the robust design of the main shell 1 and the precise fit of each component ensure the stability and reliability of the heavy-duty gear assembly during the operation of the mixer truck, improving the working efficiency of the mixer truck.

[0019] In this embodiment, preferably, the heat pipe heat dissipation mechanism includes multiple heat pipe radiators 9, each heat pipe radiator 9 being an L-shaped heat pipe. These multiple heat pipe radiators 9 are evenly spaced on both sides of the heat dissipation oil reservoir 4. The bottom of each heat pipe radiator 9 is bent towards the center of the heat dissipation oil reservoir 4 to form an L-shape. Multiple heat dissipation fins 10 are evenly distributed and fixed at the upper end of the upper shell cover 3. The multiple heat pipe radiators 9 on both sides are embedded in the corresponding heat dissipation fins 10 after penetrating the upper shell cover 3. The heat pipe radiators 9 quickly dissipate heat from the heat dissipation oil reservoir 4, and the heat is dissipated into the air through the heat dissipation fins 10, effectively improving heat dissipation efficiency. This avoids the lubrication efficiency reduction and adhesion failure of the heavy-duty gear assembly due to excessively high oil temperature, further extending the service life of the gear assembly and improving the overall performance and stability of the mixer truck.

[0020] In this embodiment, preferably, a filter screen 7 is fixedly connected to both sides of the bottom of the heat dissipation oil storage tank 4 corresponding to the oil drip port 6; the filter screen 7 can effectively filter impurities and iron filings in the lubricating oil, ensuring the cleanliness of the lubricating oil and further improving the lubrication effect and operational stability of the gear assembly.

[0021] In this embodiment, preferably, a plurality of iron filings adsorption magnets 8 are provided on the upper side of the bottom of the heat dissipation oil storage tank 4 corresponding to the outer side of the filter screen 7, and the plurality of iron filings adsorption magnets 8 are arranged at equal intervals; by setting the iron filings adsorption magnets 8, iron filings in the lubricating oil can be effectively adsorbed, ensuring the cleanliness of the lubricating oil and further improving the lubrication effect and operational stability of the gear assembly.

[0022] In this embodiment, preferably, a fixed top plate 11 is fixedly connected to the upper ends of multiple iron filings attracting magnets 8 on the same side, and a hanging sleeve plate 12 is movably sleeved on the multiple iron filings attracting magnets 8. A limiting horizontal plate 14 is provided on the upper side of the hanging sleeve plate 12, and an operating lever 13 is fixedly connected to the upper end of the fixed top plate 11 corresponding to the position of the limiting horizontal plate 14. The upper end of the operating lever 13 passes through the limiting horizontal plate 14 and is connected to a horizontal handle. Through the fixed top plate 11, multiple iron filings attracting magnets 8 can be connected and fixed. By utilizing the gaps between multiple iron filings adsorbing magnets 8 and allowing lubricating oil to pass through, the iron filings in the lubricating oil are attracted to the iron filings adsorbing magnets 8. Simultaneously, the design of the scraper plate 12 allows for quick iron filings removal. When iron filings need to be cleaned, simply pull the operating rod 13 upwards. The operating rod 13 moves the fixed top plate 11 upwards, causing the scraper plate 12 to scrape off the iron filings adsorbed on the outer wall of the iron filings adsorbing magnets 8. This achieves the purpose of quickly cleaning iron filings, preventing iron filings from accumulating and affecting the adsorption effect of the iron filings adsorbing magnets 8, further improving the lubrication effect and operational stability of the gear assembly. Furthermore, the design of the operating rod 13 and the horizontal handle makes the iron filings cleaning operation more convenient and labor-saving, improving work efficiency.

[0023] In this embodiment, preferably, a return spring 15 is fixedly connected between the bottom two sides of the limiting horizontal plate 14 and the chip-collecting sleeve plate 12. The return spring 15 allows the chip-collecting sleeve plate 12 to automatically reset after the operating lever 13 moves the fixed top plate 11 and the chip-collecting magnet 8 upwards to complete chip cleaning, facilitating continued use. Thus, the return spring 15 not only ensures the stability and reliability of the chip-collecting sleeve plate 12 but also further simplifies the operation process, making chip cleaning more efficient and continuous. Furthermore, the use of the return spring 15 reflects the thoughtful consideration in the detailed design of this invention, aiming to provide users with a more convenient and efficient gear assembly maintenance experience.
