Description

Technical Field

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

[0002] As a key component of turbomachinery, the turbine housing plays a crucial role in numerous fields such as energy, chemical industry, and aerospace. In the energy sector, turbine housings are used in power generation equipment, utilizing energy sources such as steam and natural gas to drive turbine rotation, achieving efficient energy conversion and transfer, transforming thermal energy into electrical energy, and providing stable power support for social production and daily life.

[0003] Chinese Patent Publication No. CN222759616U discloses a turbine housing, including a turbine housing body. An annular groove is formed on the inner side of the turbine housing body, and an annular magnet plate is adsorbed and fixed inside the annular groove. A heat dissipation plate is installed on one side of the annular magnet plate. The design, incorporating components such as the annular groove, heat dissipation plate, annular magnet plate, mounting holes, heat dissipation holes, a handheld rod, mounting screws, an extension rod, fixing holes, fixing bolts, and a scraper, effectively solves the problem of turbine housings generating a large amount of heat during actual use. Existing turbine housings lack effective heat dissipation structures, easily leading to excessively high internal temperatures and malfunction. Furthermore, the turbine housing draws in a large amount of air during use, causing a large amount of impurities to adhere to the inner wall. If not treated promptly, this can also prevent the turbine housing from functioning properly.

[0004] In the existing technology, during the use of a turbine box, no compensation or calibration structure is set for the core transmission components such as bearings and turbine shaft. This cannot reduce the decrease in transmission accuracy caused by installation deviations and long-term wear, and is prone to problems such as unstable power transmission and equipment vibration. Therefore, we have made improvements to this and proposed a turbine box. Utility Model Content

[0005] The purpose of this invention is to address the problem that current turbine housings do not consider the eccentricity error of transmission components.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] A turbine housing can slide within a first bearing via a T-shaped slide bar, and a cross-shaped block can slide within a second bearing. Together with springs on both sides, they can automatically compensate for the positional deviation between the two bearings, ensuring that the two bearings rotate stably at all times, significantly reducing transmission eccentricity error, and thus improving the aforementioned problems.

[0008] The application is as follows:

[0009] A turbine housing includes a first housing body, a connecting housing, and a side cover. The first housing body is fixedly connected to the connecting housing. The connecting housing includes a first bearing and a second bearing, which pass through one side of the connecting housing and the side cover respectively and are rotatably connected thereto. A T-shaped slide rod is provided on the side of the first bearing near the second bearing. The T-shaped slide rod is inserted into the interior of the first bearing and is slidably connected thereto. A cross-shaped block is fixedly installed on the side of the T-shaped slide rod near the second bearing. The cross-shaped block is inserted into the interior of the second bearing and is slidably connected thereto. Several springs are fixedly installed on the sides of the T-shaped slide rod and the cross-shaped block that are away from each other. The ends of the springs away from the T-shaped slide rod are fixedly connected to the first bearing and the second bearing respectively.

[0010] As a preferred technical solution of this application, a T-shaped cylinder is provided between the connecting box and the side box cover. The connecting box is fixedly connected to the T-shaped cylinder, and the T-shaped cylinder is slidably connected to the side box cover. The first bearing and the second bearing are both rotatably connected to the T-shaped cylinder. A sealing ring is embedded on the T-shaped cylinder and at the junction of the T-shaped cylinder and the second bearing.

[0011] As a preferred technical solution of this application, a breathing valve is slidably connected to the top of the first box, and a waterproof and breathable membrane and a filter plate are arranged sequentially from top to bottom at the bottom of the breathing valve, and both the waterproof and breathable membrane and the filter plate are inserted into the interior of the first box and slidably connected thereto.

[0012] As a preferred technical solution of this application, a pressure monitoring instrument is embedded in the top of the connecting box, and a through groove that cooperates with the filter plate is opened on the top of the first box, and the diameter of the through groove is smaller than the diameter of the filter plate.

[0013] As a preferred technical solution of this application, a fixing seat is fixedly installed on each of the corresponding sides of the connecting box, and a plug is fixedly installed on each of the corresponding sides of the side box cover. The two plugs are respectively inserted into the interior of the two fixing seats and slidably connected with them. Several fixing bolts are provided on the side of the two plugs away from the first box body. The several fixing bolts are inserted into the interior of the fixing seat and threadedly connected with it. The several fixing bolts pass through the plug and are threadedly connected with it.

[0014] As a preferred technical solution of this application, a control module is fixedly installed inside the first box, the control module is electrically connected to the breathing valve, and a fixed base is fixedly installed at the bottom of the first box, with fixing holes provided at the four corners of the fixed base.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

[0017] (1) The T-shaped slide bar can slide in the first bearing, and the cross-shaped block can slide in the second bearing. Together with the springs on both sides, they can automatically compensate for the positional deviation between the two bearings, so that the two bearings can always rotate stably, greatly reducing the transmission eccentricity error and improving the power transmission accuracy. When the equipment load changes suddenly (such as the moment of starting and stopping of construction machinery), the spring will transform the rigid impact force into elastic potential energy through compression or stretching deformation, reducing the rigid wear of the first bearing, the second bearing and the turbine shaft.

[0018] (2) The adaptive pressure regulation function of the breather valve avoids damage to the box seals and leakage of lubricating oil due to excessive pressure inside the box, or forced intrusion of outside air due to excessive pressure, thus protecting the integrity of the box structure. The double protection of the waterproof and breathable membrane and the filter plate effectively prevents water vapor and dust from entering the box, and prevents internal control modules, bearings and other components from getting damp and rusted or contaminated by impurities, thereby reducing the failure rate.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0031] Example 1: Please refer to the appendix of the instruction manual. Figure 1-3, a turbine housing, comprising a first housing 1, a connecting housing 2, and a side housing cover 3. The first housing 1 is fixedly connected to the connecting housing 2. The connecting housing 2 includes a first bearing 4 and a second bearing 5, and the first bearing 4 and the second bearing 5 pass through one side of the connecting housing 2 and the side housing cover 3 respectively and are rotatably connected thereto. A T-shaped slide rod 9 is provided on the side of the first bearing 4 near the second bearing 5. The T-shaped slide rod 9 is inserted into the interior of the first bearing 4 and is slidably connected thereto. A cross-shaped block 6 is fixedly installed on the side of the T-shaped slide rod 9 near the second bearing 5. The cross-shaped block 6 is inserted into the interior of the second bearing 5 and is slidably connected thereto. Several springs 7 are fixedly installed on the sides of the T-shaped slide rod 9 and the cross-shaped block 6 that are away from each other. The ends of the several springs 7 that are away from the T-shaped slide rod 9 are fixedly connected to the first bearing 4 and the second bearing 5 respectively.

[0032] In this embodiment of the invention, when the turbine box is running, the turbine shaft drives the first bearing 4 and the second bearing 5 to rotate synchronously. Due to possible load fluctuations, speed changes, or installation errors during equipment operation, slight coaxiality deviations or axial displacements may occur between the first bearing 4 and the second bearing 5. If the first bearing 4 and the second bearing 5 are axially offset, the T-shaped slide bar 9 will slide axially within the first bearing 4, and the cross block 6 will slide synchronously within the second bearing 5. At this time, the springs 7 on both sides will undergo compression or stretching deformation due to the displacement of the slide bar / slider. The deformation of the springs 7 will generate a reverse elastic force, which applies a buffer force to the two bearings through the T-shaped slide bar 9 and the cross block 6 to offset the impact force caused by the axial offset. At the same time, through the sliding cooperation between the slide bar and the bearing, the relative position of the two bearings is adaptively adjusted to ensure that the two always maintain a stable rotational cooperation relationship.

[0033] In this embodiment of the utility model, the T-shaped slide bar 9, the cross-shaped block 6, and the spring 7 work together to automatically compensate for the coaxiality deviation and axial displacement of the first bearing 4 and the second bearing 5 caused by load and speed changes, thereby reducing the eccentricity error in the transmission process and improving the power transmission accuracy. The elastic buffering effect of the spring 7 can effectively absorb the impact force and vibration when the bearing rotates, reduce the rigid wear of the first bearing 4, the second bearing 5, and the turbine shaft, and significantly extend the service life of the core transmission components. The fixedly connected first housing 1 and connecting housing 2 provide stable support for the bearing assembly. With the adaptive buffering structure, the turbine housing can adapt to usage scenarios with large load fluctuations and complex operating conditions, thereby improving operational stability.

[0034] Example 2: Please refer to the appendix of the instruction manual. Figure 1 -5. As a preferred embodiment of the present utility model, a T-shaped cylinder 8 is provided between the connecting box 2 and the side box cover 3. The connecting box 2 is fixedly connected to the T-shaped cylinder 8, and the T-shaped cylinder 8 is slidably connected to the side box cover 3. The first bearing 4 and the second bearing 5 are both rotatably connected to the T-shaped cylinder 8. A sealing ring is embedded on the T-shaped cylinder 8 and at the junction of the T-shaped cylinder 8 and the second bearing 5.

[0035] A breathing valve 14 is slidably connected to the top of the first housing 1. The breathing valve 14 is fixedly connected to the first housing 1 by a screw. A waterproof and breathable membrane 15 and a filter plate 16 are arranged sequentially from top to bottom at the bottom of the breathing valve 14. Both the waterproof and breathable membrane 15 and the filter plate 16 are inserted into the interior of the first housing 1 and slidably connected thereto.

[0036] A pressure monitor 13 is embedded in the top of the connecting box 2. The top of the first box 1 is provided with a through groove that matches the filter plate 16, and the diameter of the through groove is smaller than the diameter of the filter plate 16.

[0037] Fixed seats 10 are fixedly installed on the corresponding sides of the connecting box 2, and plug blocks 11 are fixedly installed on the corresponding sides of the side box cover 3. The two plug blocks 11 are respectively inserted into the two fixed seats 10 and slidably connected with them. Several fixing bolts 12 are provided on the side of the two plug blocks 11 away from the first box 1. The several fixing bolts 12 are inserted into the fixed seats 10 and threadedly connected with them. The several fixing bolts 12 pass through the plug blocks 11 and are threadedly connected with them.

[0038] A control module 17 is fixedly installed inside the first housing 1. The control module 17 is electrically connected to the breathing valve 14 and to the external controller. A fixed base is fixedly installed at the bottom of the first housing 1, and fixing holes are opened at the four corners of the fixed base.

[0039] In this embodiment of the utility model, the T-shaped cylinder 8 forms a rigid support structure spanning the connecting box 2 and the side cover 3 through a fixed connection with the connecting box 2. The first bearing 4 and the second bearing 5 are installed with the T-shaped cylinder 8 as a reference to avoid bearing shaking due to the assembly gap between the connecting box 2 and the side cover 3. At the same time, the sliding connection between the T-shaped cylinder 8 and the side cover 3 allows for synchronous adjustment of the position when the side cover 3 is disassembled and assembled, without affecting the installation accuracy of the bearing. The turbine housing usually needs to be filled with lubricating oil to reduce bearing wear. The sealing ring at the junction of the T-shaped cylinder 8 and the second bearing 5 can tightly fit the mating surfaces of the two. During the rotation of the bearing, the elastic deformation of the sealing ring fills the gap, preventing internal lubricating oil leakage and preventing external dust, moisture and other impurities from entering the housing.

[0040] In this embodiment of the invention, when the turbine box is running, the friction of internal components generates heat, causing air to expand and the pressure inside the box to rise. When the pressure reaches the set opening pressure of the breather valve 14, the breather valve 14 automatically opens, and the hot air inside the box is discharged through the waterproof and breathable membrane 15 and the filter plate 16, reducing the pressure inside the box to the normal range. When the equipment stops and cools down, and the pressure inside the box is lower than the external atmospheric pressure, the breather valve 14 opens again, and the outside air enters the box after being filtered by the filter plate 16 and dehumidified by the waterproof and breathable membrane 15, maintaining pressure balance. When the outside air enters the box, it first passes through the filter plate 16, whose pores can intercept solid impurities such as dust and particles in the air. Then it passes through the waterproof and breathable membrane 15, which has the characteristics of "breathable but not leaky", preventing rainwater and water vapor from entering the box while ensuring normal air circulation. The two work together to form a double protection of "filtering first and then moisture protection".

[0041] The pressure monitor 13 monitors the pressure changes in the connection box 2 in real time and feeds the data back to the external controller (or field display panel). When the pressure in the box rises abnormally (such as the pressure cannot be released due to a malfunction of the breather valve 14) or drops abnormally (such as leakage in the box), the pressure monitor 13 can issue an early warning signal in time to remind the operator to troubleshoot the fault. The filter plate 16 is inserted into the box through the through groove at the top of the first box 1. Since the diameter of the through groove is smaller than the diameter of the filter plate 16, the edge of the filter plate 16 will be stuck below the through groove, forming an axial limit to prevent the filter plate 16 from shifting or falling off due to vibration during equipment operation, thus ensuring that its filtration function is stable.

[0042] When installing the side box cover 3, align the inserts 11 on both sides of the side box cover 3 with the fixing seats 10 on both sides of the connecting box 2, and slide them into the slots of the fixing seats 10 to make the side box cover 3 fit against the connecting box 2; then pass the fixing bolts 12 through the bolt holes of the fixing seats 10 and the inserts 11, tighten the bolts, and lock the inserts 11 and the fixing seats 10 through the threaded engagement to complete the fixing of the side box cover 3; loosen the fixing bolts 12, pull the side box cover 3 away from the connecting box 2, and let the inserts 11 slide out of the slots of the fixing seats 10, so that the side box cover 3 can be quickly removed.

[0043] As the "control center" of the turbine housing, the control module 17 can receive control signals sent by external controllers (such as PLC control cabinets and remote control systems) in real time. After processing by the internal chip, it drives the actuators (such as speed regulating mechanism and braking components) in the housing to adjust their operating status. At the same time, the control module 17 can also collect the operating data of the turbine housing (such as speed and temperature) and feed it back to the external controller to realize closed-loop control. When installing the turbine housing, align the four corner fixing holes of the fixed base with the preset holes on the mounting plane, drive in the screws and tighten them to make the fixed base fit tightly with the mounting plane. The rigid support of the fixed base will stably fix the turbine housing and prevent the equipment from shifting due to vibration during operation.

[0044] 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.
