Abstract
Description
Technical Field
[0001] This invention relates to a flexible transmission structure for an annular cooler. Background Technology
[0002] The annular cooler is a key piece of equipment in the sintering process used to cool high-temperature sintered ore. The stability of its transmission structure directly affects the cooling efficiency and equipment lifespan. Traditional annular coolers mostly use friction wheel drives or rigid gear drives, which have significant drawbacks: friction wheel drives are prone to slippage leading to drive failure, requiring additional monitoring devices and increasing maintenance costs; while rigid gear drives are prone to stress concentration due to installation errors or thermal deformation, accelerating component wear, and are difficult to adapt to the heavy-duty conditions of large annular coolers. In addition, insufficient rigidity of the transmission structure can exacerbate the failure of the trolley seals, leading to cold air leakage, reducing cooling efficiency and increasing energy consumption.
[0003] In recent years, some improvement schemes have attempted to alleviate the above problems through flexible technologies. For example, multi-point meshing flexible transmission mechanisms reduce dynamic load impacts through power splitting and buffering devices, but their structure is complex and their manufacturing cost is high, and there is insufficient research on the flexible adaptability of the transmission system.
[0004] Therefore, there is an urgent need to develop a flexible transmission structure that combines high transmission accuracy, strong load adaptability, and low maintenance cost to solve the bottleneck problems of traditional transmission methods in terms of reliability, energy efficiency, and large-scale applications. Summary of the Invention
[0005] To overcome the above-mentioned defects, the purpose of this invention is to propose a flexible transmission structure for an annular cooler.
[0006] To achieve the above objectives, the flexible transmission structure of the annular cooler of the present invention includes a flexible base, a driving component is provided on the flexible base, and a transmission pin gear is provided on the output shaft of the driving component.
[0007] Furthermore, the flexible base includes a fixed base; an upper sliding plate is slidably disposed on the sliding base;
[0008] A left-side elastic damper device is hinged to the bottom of the fixed base; the free end of the left-side elastic damper device is hinged to the lower surface of the upper slide plate. A right elastic damping device is hinged to the bottom of the fixed base corresponding to the left elastic damping device. The free end of the right elastic damper device is hinged to the left elastic damper device, and the included angle between the right elastic damper device and the left elastic damper device is 60 degrees to 150 degrees.
[0009] Furthermore, there are two left-side elastic damper devices, which are integrally connected by a connecting rod in the middle; the free end of the right-side elastic damper device is hinged to the connecting rod.
[0010] Furthermore, the cross-section of the fixed base is U-shaped.
[0011] Furthermore, the drive component includes a set of drive motors and a matching bevel gear reducer. The drive motors are connected to the input shaft of the matching bevel gear reducer in the form of a front flange. The bevel gear reducer amplifies and rotates the input torque of the drive motors at a right angle before finally outputting it to the transmission pin gear.
[0012] Furthermore, the bevel gear reducer is mounted on the upper slide plate.
[0013] This invention enables adaptive adjustment of the drive component in the radial direction of the rotating body, ensuring tight meshing between the transmission pin gear and the rotating body pin teeth. It exhibits strong resistance to impact loads, reliable operation, compact structure, and convenient installation and maintenance. Attached Figure Description

[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0021] In the description of this invention, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0022] 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 invention, unless otherwise stated, "a plurality of" means two or more.
[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0024] like Figures 1 to 5 As shown, the flexible transmission structure of the annular cooler of the present invention mainly includes a flexible base 1, a driving component 2, and a transmission pin gear 3.
[0025] like Figure 2 As shown, the flexible base 1 is the main component of the structure of this invention, including a fixed base 1.1, an upper sliding plate 1.2, a left elastic damper 1.3, a connecting rod 1.4, a right elastic damper 1.5, and a matching pin 1.6. The fixed base 1.1 is a casting design, with a slide rail designed to mate with the upper sliding plate 1.2 in the inner lining. A self-lubricating material is used between the upper sliding plate 1.2 and the slide rail to ensure smooth and unobstructed sliding. The flexible function is achieved through the cooperation of the left elastic damper 1.3 and the right elastic damper 1.5, which are arranged diagonally in a triangle. They need to be adjusted in advance during installation. Under the action of the two, the drive unit remains stable without external impact load. The two sets of elastic dampers on the left are fixed by the connecting rod 1.4. The elastic dampers all adopt the form of end bearings and are connected to each other by the matching pin 1.6.
[0026] like Figure 3As shown, the drive component 2 includes a set of drive motors 2.1 and a matching bevel gear reducer 2.2. The drive motor 2.1 is connected to the input shaft of the matching bevel gear reducer 2.2 in the form of a front flange. The bevel gear reducer 2.2 amplifies and rotates the input torque of the drive motor 2.1 at a right angle, and finally outputs it to the transmission pin gear 3.
[0027] The working process of the flexible transmission structure is as follows: When radial displacement occurs in the rotating body of the annular cooler, this displacement is transmitted to the transmission pin gear through the rotating body. Since the transmission pin gear is fixedly connected to the bevel gear reducer, and the bevel gear reducer is fixedly connected to the upper slide plate, the displacement is ultimately transmitted to the upper slide plate of the flexible base. Because the upper slide plate of the flexible base and the fixed base are connected by an elastic damper, the displacement is ultimately canceled out by the elastic damper. Due to unavoidable manufacturing and installation errors, the aforementioned displacement is also unavoidable. This design can effectively eliminate such errors and ensure a tight engagement between the transmission pin gear and the rotating body pin teeth throughout the entire operation.
[0028] In summary, a flexible transmission structure for an annular cooler can achieve adaptive adjustment of the drive component in the radial direction of the rotating body, ensuring tight meshing between the transmission pin gear and the rotating body pin teeth. It exhibits strong resistance to impact loads, reliable operation, compact structure, and convenient installation and maintenance.
