Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, specifically a protective turbine housing. Background Technology

[0002] In the complex and precise operating systems of modern industrial production, the turbine housing, as the core hub for power transmission in mechanical equipment, undertakes important functions such as transmitting power, changing speed and torque thanks to its precise structural design and efficient transmission performance. It is widely used in aerospace, automotive manufacturing, energy and power industries, playing an irreplaceable role in key aspects such as power conversion in aircraft engines, speed regulation in automotive transmissions, and torque matching in wind turbine generators.

[0003] Chinese Patent Announcement No. CN208237013U discloses a reinforced turbine gearbox, the structure of which includes a turbine gearbox body, an upper housing, a lower housing, a worm gear mechanism, a turbine mechanism, and a pinion. The turbine gearbox body includes an upper housing and a lower housing, the lower housing being detachably connected to the upper housing. The lower housing is equipped with a worm gear mechanism, the worm gear mechanism having a worm shaft, and a gear in the middle of the worm shaft. The worm shaft and the gear are fixed together, and bearings are provided at both ends of the gear, the bearings being fixedly connected to the gear. A high-speed driven wheel is provided on the left side of the worm shaft, and the worm shaft is fixedly connected to the high-speed driven wheel. The upper housing is equipped with a turbine mechanism, the upper housing being fixedly connected to the turbine mechanism, and a pinion is provided in the middle of the turbine mechanism. This reinforced turbine gearbox has a long service life, is less prone to tooth breakage, has low noise, a simple structure, and is easy to implement.

[0004] In existing technologies, the use of a reinforced turbine housing only lists the core transmission components such as the turbine housing body, upper housing, lower housing, worm gear mechanism, turbine mechanism, and pinion gear, without mentioning any structures related to heat dissipation or cooling (such as cooling pipes, cooling device interfaces, heat dissipation fins, etc.). Because the turbine housing continuously generates heat during high-speed operation, the lack of a dedicated heat dissipation and cooling design leads to the ineffective dissipation of heat, causing it to accumulate. Prolonged exposure to high temperatures significantly accelerates the wear of internal components, gradually degrades the overall performance of the equipment, and may even damage critical components due to high temperatures, drastically shortening the equipment's lifespan and failing to guarantee long-term efficient operation under stable temperatures. Therefore, we have made improvements by proposing a protective turbine housing. Utility Model Content

[0005] The purpose of this invention is to address the problem that a current reinforced turbine housing lacks a heat dissipation and cooling design, resulting in a significant risk of high-temperature operation.

[0016] In the scheme of this application:

[0030] Example 1: Please refer to the appendix of the instruction manual. Figure 1 -3, a protective turbine housing, including a turbine housing body 1, a bearing 2 on the turbine housing body 1, protective frames 4 on corresponding sides of the outer side of the turbine housing body 1, both protective frames 4 being slidably connected to the turbine housing body 1, a spiral infusion tube 3 being fixedly installed inside the turbine housing body 1, and both ends of the spiral infusion tube 3 passing through one side of the turbine housing body 1 and being fixedly connected thereto, both protective frames 4 having through grooves for slidably connecting with the spiral infusion tube 3, and a first filter plate 8 and a second filter plate 9 on corresponding sides of the turbine housing body 1, both the first filter plate 8 and the second filter plate 9 being inserted into the interior of the turbine housing body 1 and slidably connected thereto.

[0031] In this embodiment of the utility model, the core foundation of the protective turbine housing is the turbine housing body 1. Bearings 2 for power transmission and component support are mounted on the turbine housing body 1. To effectively protect the turbine housing body 1, protective frames 4 are provided on corresponding sides of its outer side. The two protective frames 4 are slidably connected to the turbine housing body 1, and their positions can be adjusted according to actual protection needs and maintenance operations. Inside the turbine housing body 1, a spiral infusion pipe 3 for cooling is fixedly installed. Both ends of the spiral infusion pipe 3 pass through one side of the turbine housing body 1 and are fixedly connected thereto. Simultaneously, through grooves are provided on both protective frames 4 for slidably connecting with the spiral infusion pipe 3, ensuring that the sliding of the protective frames 4 does not affect the normal operation of the spiral infusion pipe 3. Furthermore, to ensure the cleanliness of the inside of the turbine housing body 1, first filter plates 8 and second filter plates 9 are provided on corresponding sides. Both first filter plates 8 and second filter plates 9 are inserted into the inside of the turbine housing body 1 and slidably connected thereto, facilitating subsequent disassembly, cleaning, or replacement. The spiral infusion pipe 3 is connected to an external cooling device, providing power and cooling medium for the cooling function.

[0032] During turbine box operation, bearing 2, as a key transmission component, supports the operation of rotating parts inside the turbine box, achieving smooth power transmission. When the turbine box generates heat during long-term operation, the external cooling device is activated, delivering the cooling medium to the spiral infusion pipe 3. Since the spiral infusion pipe 3 is fixedly installed inside the turbine box body 1, the cooling medium exchanges heat with the turbine box body 1 and internal components during its flow within the pipe, absorbing the heat generated during operation. Subsequently, the cooling medium carrying the heat flows back to the cooling device for cooling, forming a continuous cooling cycle to achieve cooling of the turbine box. The two protective frames 4 are slidably connected to the turbine box body 1 and can be adjusted in position according to actual conditions, wrapping and protecting the turbine box body 1 from both sides to prevent external debris, dust, etc. from entering the box. At the same time, the first filter plate 8 and the second filter plate 9 filter the air or other media entering the turbine box body 1 during turbine box operation, blocking impurities from entering and ensuring a clean operating environment for internal components.

[0033] In this embodiment of the utility model, the cooling function achieved by the spiral infusion pipe 3 in conjunction with the external cooling device can effectively control the temperature of the turbine box during operation, avoid excessive wear and performance degradation of components due to excessive temperature, extend the service life of each component of the turbine box, and ensure that the equipment operates continuously and efficiently at a suitable temperature.

[0034] The protective frame 4 provides external protection for the turbine housing body 1, blocking external impacts and debris intrusion, reducing the risk of damage to the turbine housing body 1 from external factors; and the sliding connection between the protective frame 4 and the turbine housing body 1, as well as the sliding cooperation with the spiral infusion tube 3, allows the protective frame 4 to play a protective role without affecting the normal operation and subsequent maintenance of the spiral infusion tube 3, thus improving the flexibility of equipment use.

[0035] The filtration function of the first filter plate 8 and the second filter plate 9 effectively removes impurities from the medium entering the turbine housing body 1, preventing impurities from adhering to the surface of internal components or entering the transmission gaps. This avoids problems such as component wear and jamming, ensuring the cleanliness and smooth operation of the internal components of the turbine housing, and further improving the operational stability and service life of the equipment. At the same time, the sliding connection between the filter plates and the turbine housing body 1 facilitates regular disassembly and cleaning or replacement by personnel, reducing maintenance difficulty, time, and costs.

[0036] Example 2: Please refer to the appendix of the instruction manual. Figure 1-4. In a preferred embodiment of the present invention, the outer diameters of the two first filter plates 8 are smaller than the outer diameters of the two second filter plates 9. A plurality of second fixing bolts 11 are provided on the side of the two second filter plates 9 that are far apart from each other. The plurality of second fixing bolts 11 pass through the two first filter plates 8 and the two filter plates 9 and are threadedly connected to them. The plurality of second fixing bolts 11 are inserted into the interior of the turbine housing body 1 and are threadedly connected to it.

[0037] The bearing 2 passes through the two first filter plates 8 and is rotatably connected to them. The bearing 2 is inserted into the interior of the two second filter plates 9 and is rotatably connected to them. Sealing rings are embedded on the two first filter plates 8 and the second filter plates 9 and at the junction of the first filter plates 8 and the second filter plates 9 and the bearing 2. Sealing rings are also embedded on the turbine housing body 1 and at the junction of the turbine housing body 1 and the two first filter plates 8 and the second filter plates 9.

[0038] One of the protective frames 4 has side plates 6 fixedly installed on both sides, and the other protective frame 4 has fixed seats 7 fixedly installed on both sides. The two side plates 6 are inserted into the two fixed seats 7 and slidably connected to them. Several first fixing bolts are provided on the side of the two side plates 6 away from the fixed seats 7. The several first fixing bolts pass through the side plates 6 and are threadedly connected to them. The several first fixing bolts are inserted into the fixed seats 7 and are threadedly connected to them.

[0039] Rubber pads 5 are fixedly installed on the outer side of both protective frames 4. The rubber pad 5 on the outer side of one protective frame 4 is fixedly connected to the two side plates 6, and the rubber pad 5 on the outer side of the other protective frame 4 is fixedly connected to the two fixed seats 7. Both rubber pads 5 are provided with through grooves that are slidably connected to the spiral infusion tube 3.

[0040] Flanges 10 are fixedly installed on both sides of the turbine housing body 1, and the apertures on the two first filter plates 8 are smaller than the apertures on the second filter plate 9.

[0041] In this embodiment of the invention, since the outer diameter of the first filter plate 8 is smaller than that of the second filter plate 9, during installation, the first filter plate 8 can be tightly attached to one side of the inside of the turbine housing body 1, while the second filter plate 9 is located on the outside of the first filter plate 8, forming a dual filtration structure. When the medium enters the turbine housing body 1, it first undergoes preliminary filtration through the second filter plate 9 with a larger outer diameter, intercepting larger particles of impurities. Subsequently, it undergoes secondary filtration through the first filter plate 8, removing smaller particles of impurities, thus achieving graded filtration and improving the filtration effect. In terms of fixing, the second fixing bolt 11 passes through the first filter plate 8 and the second filter plate 9 and is threadedly connected to the turbine housing body 1. Through the tightening force of the bolt, the first filter plate 8 and the second filter plate 9 are tightly fixed to the turbine housing body 1, preventing the filter plates from loosening or shifting due to vibration or other factors during turbine housing operation, ensuring that the filter plates are always in a stable working position and continuously perform their filtration function.

[0042] The bearing 2 passes through the first filter plate 8 and is rotatably connected to the inside of the second filter plate 9. When the turbine box is running, the bearing 2 can rotate freely to achieve power transmission, while the first filter plate 8 and the second filter plate 9 remain fixed, which does not affect the normal operation of the bearing 2, and at the same time plays a filtering and protection role for the area around the bearing 2. In terms of sealing, the sealing ring at the junction of the first filter plate 8, the second filter plate 9 and the bearing 2 can effectively prevent impurities from entering the turbine box body 1 from the gap between the bearing 2 and the filter plate, and at the same time prevent the leakage of media such as lubricating oil in the box. The sealing ring at the junction of the turbine box body 1 and the first filter plate 8, the second filter plate 9 further enhances the overall sealing performance of the equipment, prevents external impurities from entering from the connection gap between the filter plate and the turbine box body 1, and also prevents the media in the box from leaking from the gap, forming all-round sealing protection.

[0043] In this embodiment of the invention, when it is necessary to adjust the relative position of the two protective frames 4 to adapt to different protection requirements or to perform maintenance operations, the first fixing bolt can be loosened first, allowing the side plate 6 to slide freely inside the fixing seat 7, thereby causing the two protective frames 4 to move closer or further apart, thus achieving position adjustment. After adjusting to the appropriate position, the first fixing bolt is tightened, and the side plate 6 is fixedly connected to the fixing seat 7 by the tightening force of the bolt, thereby keeping the two protective frames 4 in the set position, forming a stable protective structure, and protecting the turbine housing body 1 from both sides.

[0044] The rubber pad 5 is fixedly installed on the outside of the protective frame 4. When the protective frame 4 protects the turbine housing body 1, the rubber pad 5 is the outermost layer and is the first to come into contact with external objects or the environment. Due to the good elasticity of the rubber pad 5, when subjected to slight external impact or compression, the rubber pad 5 can undergo elastic deformation, absorb impact energy, and reduce the impact force on the protective frame 4 and the internal turbine housing body 1. At the same time, the wear resistance of the rubber pad 5 can reduce the wear on the outside of the protective frame 4 and extend the service life of the protective frame 4. In terms of sealing, the fixed connection between the rubber pad 5 and the protective frame 4, the side plate 6 or the fixed seat 7, and the sliding fit with the spiral infusion tube 3 can further prevent external dust, moisture and other impurities from entering from the gaps in the protective frame 4 or the connection with the spiral infusion tube 3, thereby improving the overall sealing performance of the protection.

[0045] Flanges 10 are fixed on both sides of the turbine housing body 1. During equipment installation and connection, this protective turbine housing can be connected to other transmission equipment, pipelines, or support structures through flanges 10. Workers only need to align flanges 10 with the flange interfaces of the corresponding equipment and use bolts or other fasteners to fix them, thus achieving a reliable connection between the equipment and ensuring smooth power transmission or media delivery. In terms of filtration, since the aperture of the first filter plate 8 is smaller than that of the second filter plate 9, when the media enters the turbine housing body 1, it first passes through the second filter plate 9, whose larger aperture can quickly intercept larger particles of impurities, reducing the filtration burden on the first filter plate 8. Subsequently, the media passes through the first filter plate 8, whose smaller aperture can further filter out smaller particles of impurities, achieving graded filtration from coarse to fine, ensuring that the cleanliness of the media entering the turbine housing body 1 meets the equipment operation requirements.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
