[0001] The present invention relates to the technical field of air intake guide vanes, and in particular to a floating roller ring driven air intake guide vane and a method of using the same. Background Art

[0002] In existing technology, imported guide vane guides use a drive ring to synchronously adjust the guide vane angle. Bearings or bushings are typically installed on the drive ring to ensure smooth rotation. However, existing structures have several drawbacks, notably the need for regular maintenance and component replacement, and the complex sealing housing structure, which increases the difficulty and cost of repairs. This invention aims to address the poor sealing performance and high maintenance costs of existing guide vane guides through a novel housing-less sealing structure. Summary of the Invention

[0003] The object of the present invention is to provide a floating roller ring driven inlet guide vane and a method of using the same, which have the advantages of simple structure, good sealing effect, easy maintenance and low cost.

[0004] According to one object of the present invention, the present invention provides a floating roller ring driven air intake guide vane, comprising a base and a drive ring, wherein an active guide vane and a plurality of driven guide vanes are provided inside the base, and the active guide vane and the driven guide vane are rotatably connected to the base via a rotating shaft respectively; the drive ring is sleeved on the outside of the base, and the drive ring is freely rotatable relative to the base via a plurality of floating rollers; the floating rollers are movably arranged in a reserved groove of the drive ring; each of the active guide vane and the driven guide vane is connected to the drive ring sleeved on the base via a corresponding rocker rod.

[0005] Furthermore, the rotating shafts of the active guide vanes and the driven guide vanes are rotatably arranged on the base through bearing seats respectively.

[0006] Furthermore, the shaft gaps between the active guide vanes and the driven guide vanes are provided with packing seals, and the bearing seat compresses the packing seals to form an oil film.

[0007] Furthermore, a limiting ring is fixed on the outer side of the base, and the limiting ring is used to limit the movement of the driving ring.

[0008] Furthermore, one end of the rocker arm is fixedly connected to the shaft end of the active guide vane or the driven guide vane, and the other end of the rocker arm is rotatably connected to the drive ring.

[0009] Furthermore, a fixing block is fixed to the outer side of the reserved groove by a fastener, an annular groove is opened on the base, and the floating roller rolls freely in the annular groove.

[0010] Furthermore, connecting flanges are respectively provided on both sides of the base, and a sealing ring is provided between the base and the connecting flanges.

[0011] Furthermore, an actuator mounting seat is fixed on the base, the actuator is fixed on the actuator mounting seat, and the actuator is fixedly connected to the shaft portion of the active guide vane.

[0012] Furthermore, the number of the active guide vane is one, the number of the driven guide vanes is multiple, and the active guide vane and the multiple driven guide vanes are evenly arranged inside the circumference of the base.

[0013] According to another object of the present invention, the present invention provides a method for using the floating roller ring driven inlet guide vane device, comprising the following steps:

[0014] The rotational torque of the actuator drives the active guide vanes to rotate, and the rotational torque of the active guide vanes is synchronously transmitted to the rocker arm. The rocker arm drives the drive ring to rotate along the annular trajectory on the surface of the base under the action of the floating roller. While the drive ring rotates, it also translates relative to the surface of the base. The rotation of the drive ring synchronously drives other rocker arms to drive the corresponding driven guide vanes to rotate, thereby accurately controlling the air flow and pressure and realizing synchronous adjustment of the guide vanes.

[0015] The technical solution of this invention utilizes an actuator to drive the active guide vanes, which in turn drive the driven guide vanes in a synchronous manner via a drive ring. The active and driven guide vanes are synchronized and adjusted via a precise transmission structure, enabling more accurate control of air flow and pressure, thereby optimizing the operation of the inlet guide vane. This structure reduces the number of components and optimizes the guide vane drive system. The simplified drive ring design eliminates the complex components found in traditional structures, reducing production and maintenance costs. The lack of a cover allows for easier inspection and maintenance of the guide vane, reducing the complexity of the maintenance process. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Example 1

[0029] like Figure 1-Figure 7 As shown:

[0030] A floating roller ring driven inlet guide vane device comprises a base 1, a drive ring 2, an actuator mounting seat 3, a rocker arm 4, active guide vanes 5, driven guide vanes 6, a bearing seat 7, a packing seal 8, a limit ring 9 and a connecting flange 10.

[0031] An active guide vane 5 and a plurality of driven guide vanes 6 are provided inside the base body 1 . The active guide vane 5 and the driven guide vane 6 are assembled on the base body 1 through a rotating shaft and a bearing seat 7 respectively.

[0032] The base 1 is fitted with a drive ring 2, which slides on the outside of the base 1. A limit ring 9 is also fixed to the outside of the base 1 to limit the movement of the drive ring 2. The limit ring 9 limits the position of the drive ring 2, ensuring that it does not move excessively during operation. The optimized structure of the drive ring 2 reduces the number of parts and reduces production and maintenance costs.

[0033] Specifically, if Figure 5-Figure 7 As shown, the drive ring 2 consists of a main drive ring 2-1, fixed blocks 2-2, and floating rollers 2-3. Several fixed blocks 2-2 and floating rollers 2-3 are mounted on the main drive ring 2-1. The fixed blocks 2-2 are fastened to the main drive ring 2-1 via fasteners. The floating rollers 2-3 are movably secured to the main drive ring 2-1 via the fixed blocks 2-2, allowing the floating rollers 2-3 to roll flexibly relative to the main drive ring 2-1. The coordination between the main drive ring 2-1 and the floating rollers 2-3 ensures smooth rotation of the drive ring 2, avoiding the instability of traditional bearing structures.

[0034] The number of floating rollers on the drive ring of the present invention varies depending on the diameter of the guide vane. The general principle is that the total stiffness of the floating rollers is sufficient to support the drive ring's motion and ensure smooth movement. The specific number of floating rollers can be varied depending on the guide vane diameter. In this embodiment, the main drive ring 2-1 is equipped with seven fixed blocks 2-2 and seven floating rollers 2-3. The floating rollers 2-3 are installed in pre-reserved grooves on the main drive ring 2-1. The fixed blocks 2-3 restrain the floating rollers, preventing them from slipping out of the reserved grooves. The fixed blocks 2-2 are fastened to the main drive ring 2-1 with fasteners. The drive ring 2 structure, consisting of the main drive ring 2-1, fixed blocks 2-2, and floating rollers 2-3, ensures smooth rotation and is more stable than traditional bearing structures. The base 1 is provided with an annular groove, along which the rolling paths of the floating rollers 2-3 follow, ensuring that the drive ring 2 only moves in a circular motion around the base 1. By disposing the floating rollers 2 - 3 , the driving ring 2 can move smoothly relative to the base 1 while ensuring the motion trajectory, thereby reducing the possibility of the driving mechanism getting stuck.

[0035] Each active guide vane 5 and driven guide vane 6 has a connecting shaft exposed outside the bearing seat 7, each connected to a rocker arm 4. The other end of the rocker arm 4 is connected to the drive ring 2 sleeved on the base 1. Specifically, one end of the rocker arm 4 is fixedly connected to the shaft end of the active guide vane 5 or driven guide vane 6, and the other end of the rocker arm 4 is rotatably connected to the drive ring 2.

[0036] In this embodiment, one active guide vane 5 and six driven guide vanes 6 are provided. One active guide vane 5 and six driven guide vanes 6 are respectively assembled on the base 1 through a bearing seat 7. Each active guide vane 5 and driven guide vane 6 is connected to the drive ring 2 sleeved on the base 1 through a corresponding rocker rod 4, and the drive ring 2 is limited by a limit ring 9.

[0037] A packing seal 8 is installed in the axial clearance between the active and driven guide vanes 5 and 6 and compressed by the bearing seat 7. The bearing seat 7 compresses the packing seal 8, forming an oil film that effectively isolates the gas. The packing seal 8 is made of highly wear-resistant material, which effectively reduces wear during long-term use, improving sealing performance and service life.

[0038] Connecting flanges 10 are respectively provided on both sides of the base 1 , and the base 1 and the connecting flanges 10 are sealed by a sealing ring to prevent air leakage.

[0039] An actuator mounting seat 3 is fixed on the base 1, and the actuator is installed on the actuator mounting seat 3. The actuator drives the active guide vanes 5 and the rocker rod 4 connected to the active guide vanes 5 to rotate, and then the rocker rod 4 drives the driving ring 2 to rotate relative to the base 1. The rotation of the driving ring 2 drives the other rocker rods 4 to rotate, so that the movement of these rocker rods synchronously drives the rotation of the driven guide vanes 6, thereby realizing synchronous adjustment of the active guide vanes 5 and the driven guide vanes 6, and can accurately control the air flow and pressure, thereby playing a role in adjusting the working state of the intake guide vane.

[0040] When used, the present invention comprises the following steps:

[0041] The rotational torque of the actuator drives the active guide vanes 5 to rotate, and the rotational torque of the active guide vanes 5 is synchronously transmitted to the rocker 4. The rocker 4 drives the drive ring 2 to rotate along the annular trajectory on the surface of the base 1 under the action of the floating roller. While the drive ring 2 rotates, it also translates relative to the surface of the base 1. The rotation of the drive ring 2 synchronously drives other rocker rods 4 to drive the corresponding driven guide vanes 6 to rotate, thereby realizing synchronous adjustment of the guide vanes.

[0042] The present invention significantly reduces the number of parts, adopts a simplified drive ring design, removes complex parts in traditional structures, and reduces production and maintenance costs.

[0043] The present invention significantly improves the sealing performance of the product, prevents gas leakage through packing sealing, compression of the bearing seat and oil film formation, effectively improves the sealing effect and ensures the efficient operation of the guide vane.

[0044] The present invention can improve product stability, avoid the instability of the traditional bearing structure through the cooperation of the floating roller and the main ring of the driving ring, ensure the smooth rotation of the driving ring, and reduce the failure rate.

[0045] The present invention has good synchronous adjustment capability. The active guide vanes and the driven guide vanes are synchronously adjusted through a precise transmission structure, which can more accurately control the air flow and pressure, thereby optimizing the working state of the intake guide vane.

[0046] The present invention simplifies maintenance work. Since there is no cover structure, the guide vane can be observed and repaired more conveniently, reducing complicated maintenance procedures.

[0047] The present invention optimizes the transmission structure of the guide vane, reduces the number of parts, and lowers maintenance costs; improves the sealing performance of the guide vane, and facilitates observation and maintenance without the need for a cover; has a simple structure and low cost, and has more advantages than a cover-type sealed guide vane.

[0048] This invention offers the advantages of a simple structure, excellent sealing, easy maintenance, and low cost. The vane guide adopts a novel sealing design, with a drive ring driving the driven and active guide vanes. The bearing seat compresses the packing seal, creating a strong oil film and isolating the gas. This structure reduces the number of components and optimizes the vane guide's transmission system.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
