Further, servomotor comprises output shaft, and parallelogram linkage comprises first steel pole, and output shaft connects first end of first steel pole.
Further; Parallelogram linkage also comprises second steel pole and the 3rd steel pole; The first end hinge of second steel pole is at second end of first steel pole, and the first end hinge of the 3rd steel pole is at second end of second steel pole, and second end of the 3rd steel pole is linked optionally with throttle and/or guide vane.
Further, the equal in length of first steel pole and the 3rd steel pole.
Further, the length of second steel pole equates with the distance of output shaft to throttle and/or guide vane.
Further, servomotor also is connected in a control device, and control device is through the control servomotor motion that transmits control signal.
Further, regulating device also comprises holder, and servomotor is fixed on the holder.
The present invention has following beneficial effect: engine adopts regulating device of the present invention can realize the throttle and the guide vane of engine evenly and are accurately regulated in the process of test run.
Except top described purpose, feature and advantage, the present invention also has other purpose, feature and advantage.To do further detailed explanation to the present invention with reference to figure below.
Description of drawings
The accompanying drawing that constitutes the application's a part is used to provide further understanding of the present invention, and illustrative examples of the present invention and explanation thereof are used to explain the present invention, do not constitute improper qualification of the present invention.In the accompanying drawings:
Fig. 1 is the structural representation of the regulating device that is used for engine run of the preferred embodiment of the present invention; And
Fig. 2 is the structural representation of the parallelogram linkage of the preferred embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
Referring to Fig. 1, regulating device of the present invention is used to regulate the throttle and the guide vane of engine in the commissioning process of engine.Regulating device comprises holder 1 and servomotor 3, and wherein, servomotor 3 is installed on the holder 1 regularly.Regulating device also comprises parallelogram linkage 5, and first end of parallelogram linkage 5 directly connects the output shaft 31 of servomotor 3, and second end of parallelogram linkage 5 selectively connects the throttle and/or the guide vane of engine.Regulating device of the present invention also is connected with a control device, and control device transmits control signal to servomotor 3, and servomotor 3 makes the output shaft 31 of servomotor 3 rotate first angle according to the control signal that receives.When the output shaft 31 of servomotor 3 in the process of rotation first angle, the parallelogram linkage 5 that is connected in output shaft 31 drives throttles and/or guide vane also rotates first angle.The regulating device that is used for engine run of the present invention is regulated folding degree and/or the air inflow of guide vane of the throttle of engine through the anglec of rotation that changes throttle and/or guide vane.
Regulating device of the present invention adopts aforesaid way that the throttle and/or the guide vane of engine are regulated; Do not need to be provided with again flexible axle; Thereby reduced departure, and then even regulation throttle and/or guide vane, and reached the purpose of accurate adjusting throttle and/or guide vane.
In the above-mentioned embodiment of regulating device of the present invention; Servomotor 3 makes the output shaft 31 of servomotor 3 rotate first angle according to the control signal of receiving, output shaft 31 also rotates first angle through parallelogram linkage 5 drive throttles and/or guide vane.First angle of output shaft 31 rotations of servomotor 3 is identical with first angle of throttle and/or guide vane rotation, is because adopted parallelogram linkage as shown in Figure 25.
As shown in Figure 2, parallelogram linkage 5 comprises the first steel pole a, the second steel pole c and the 3rd steel pole b.Wherein, The first end d1 of the first steel pole a is connected in the output shaft 31 of servomotor 3; Second end of the first steel pole a is hinged on first end of the second steel pole c through the first hinge d3; Second end of the second steel pole c is hinged on first end of the 3rd steel pole b through the second hinge d4, and second end of the 3rd steel pole b is linked optionally with the throttle and/or the guide vane of engine.In this parallelogram linkage 5; The equal in length of the length of the first steel pole a and the 3rd steel pole b; The length of the second steel pole c equates that with the first end d2 distance of the first end d1 to the, the three steel pole b of the first steel pole a promptly be: the length of the second steel pole c equates with the distance of output shaft 31 to throttle and/or guide vane.Therefore, the first steel pole a, the second steel pole c and the 3rd steel pole b constitute the planar linkage mechanism of parallelogram.When the output shaft 31 drives first steel pole a of servomotor 3 forwards a ' position to; Correspondingly; The second steel pole c forwards c ' position under the drive of the first hinge d3; The 3rd steel pole b forwards b ' position under the drive of the second hinge d4, simultaneously, the first hinge d3 and the second hinge d4 lay respectively at the position of d3 ' and d4 '.At this moment, throttle and/or guide vane also rotate to b ' position under the drive of the 3rd steel pole b.Can be known by parallelogram principle: ∠ aa '=∠ bb ', promptly first angle of output shaft 31 rotations of servomotor 3 equals first angle of throttle and/or guide vane rotation.
In other embodiment of the present invention; Like need the throttle and the guide vane of engine are regulated respectively; Can adopt above-mentioned regulating device to realize the control to throttle on the one hand, simultaneously, the regulating device that can also set up a cover same structure realizes the adjusting to guide vane.
To sum up, engine adopts regulating device of the present invention can realize the throttle and the guide vane of engine evenly and are accurately regulated in the process of test run.
