Referring to Fig. 1, an embodiment of valve rod driving mechanism proposed by the present invention, in the present embodiment, valve rod driving mechanism
Including mounting portion, valve rod 100 and driving device 210, wherein mounting portion (attached drawing is not shown) is used to valve rod driving mechanism
The carrier of installation space and installation site is provided, valve rod 100 is axially and movably installed on mounting portion along it, and driving device 210 is pacified
Loaded on mounting portion and positioned at the side of valve rod 100, driving device 210 is drivingly connected valve rod 100 by interlinked mechanism, to drive
Ovable valve stem 100 is along its axial activity.Since valve rod 100 is connect with flap 110, valve rod 100 is along its axial activity, that is, valve
Bar 100 is to the opening and closing process of valve body, in the present embodiment, valve rod 100 along its axial activity in addition to axial up and down along it,
It further comprises along its axial rotary motion, in addition, when 100 length of valve rod is longer, if driving device 210 and gearing machine
Structure and valve rod 100 are coaxially disposed, and the structure of valve rod 100, mounting portion and valve body (attached drawing is not shown) can become complicated, are occupied empty
Between it is big, be unfavorable for the arrangement of valve rod 100, mounting portion and valve body, in the present embodiment, driving device 210 is located at the one of valve rod 100
Side reduces the occupied space of valve rod 100 and mounting portion, keeps valve body and valve rod driving mechanism integrally more compact.
Further, driving device 210 has drive shaft 211, and drive shaft 211 can axially be rotated around itself, the present embodiment
In, driving device 210 is motor, has the characteristics that control precision height, swift, serial verb construction drive connection 211 He of drive shaft
Valve rod 100, drive shaft 211 is converted to valve rod 100 along its axial active strokes.The driving of drive shaft 211 connects
Transmission mechanism is connect, transmission mechanism band ovable valve stem 100 is made to carry out up and down, driving device while with the rotation of itself axis
The revolving speed of 210 rotation-controlleds controls the height of valve rod 100, can precisely control valve rod 100 to the open and close control of valve body.
Please refer to Fig. 1-Fig. 3, serial verb construction includes guide sleeve 330 and gear set, guide sleeve 330 vertically to extending and
Upper and lower opening setting, guide sleeve 330 are sheathed on the upper end of valve rod 100, and guide sleeve 330 is fixedly installed in mounting portion, and gear set is set
Between guide sleeve 330 and drive shaft 211, gear set engages connection with drive shaft 211 and valve rod 100, to pass through drive shaft
211 band ovable valve stems 100 rotate, wherein and the part that the upper end of valve rod 100 is located in guide sleeve 330 is laterally convexly equipped with idler wheel 310,
The inner sidewall of guide sleeve 330 corresponds to idler wheel 310 and offers guide groove 320, and idler wheel 310 and guide groove 320 form guiding cooperation, lead
It is vertically obliquely installed to slot 320, valve rod 100 is converted into valve rod 100 in the active strokes of upward and downward.Pass through tooth
Wheel group, which is realized, to be interlocked, and high transmission accuracy is high-efficient, big to the transmission range of revolving speed, and reliable operation, and the service life is long, in addition,
In the present embodiment, the position of guide sleeve 330 is fixed, when transmission mechanism band ovable valve stem 100 rotates, the rolling that is connect with valve rod 100
Wheel 310, which is followed by, to be rolled and is rotated in guide groove 320, therefore guide groove 320 can play guiding to idler wheel 310 and adjustment is high
The effect of degree, while rolling of the idler wheel 310 in guide groove 320 is converted by the lateral force that valve rod 100 is subject to, specifically, if
The adjustment of the maximum displacement and displacement accuracy up and down to valve rod 100 may be implemented in the length and gradient for setting guide groove 320,
Therefore it is accurate to the control of the up and down stroke of valve rod 100 to improve valve rod driving mechanism for the cooperation of idler wheel 310 and guide groove 320
Degree, while guide groove 320 can reduce shaking and the card of valve rod 100 to the guiding of idler wheel 310 with valve rod 100 when up and down
It is stagnant, move valve rod 100 more stable.
Specifically, gear set includes first gear group 220 and second gear group, and first gear group 220 is close to drive shaft
211 and connection is engaged with drive shaft 211, second gear group includes being set to 100 upper end of valve rod and the wheel disc coaxial with valve rod 100
231, at least part periphery wall of wheel disc 231 extends towards first gear group 220, and to form scallop 232, scallop 232 is right
First gear group 220 is answered to be toothed around, wherein the bottom surface of wheel disc 231 is equipped with vertically to the connecting rod of extension 234, connecting rod
234 lower end and valve rod 100 can be up and down connect.Since the up and down stroke of valve rod 100 is limited, wheel disc 231
The quantity of the gear teeth need not be arranged excessively, wheel disc 231 can save the occupied space of gear set, this reality by forming scallop 232
Apply in example, first gear group 220 includes gear shaft and superposition and the duplicate gear of radius not etc. up and down, gear shaft vertically to
Extend, can vertically to axis be rotatably mounted to mounting portion, duplicate gear is corresponding with drive shaft 211 and scallop 232
Gear teeth meshing, to change revolving speed.
In the present embodiment, driving device 210 is motor, it is contemplated that the steering of the drive shaft 211 of motor can exist can not be anti-
The case where turning, the upper end of wheel disc 231 are equipped with return unit 233, return unit 233 reset the rotation of wheel disc 231, and then with drive
Dynamic device 210 is worked in coordination, and control valve rod rotation direction, revolving speed etc., specifically, return unit 233 are the bullet in compressive state
Spring, spring are applied with pretightning force to wheel disc 231, namely to valve rod 100, the becoming with itself axis rotary motion that have valve rod 100
Gesture, the direction of rotation of direction of rotation and 210 driving stem 100 of driving device under no pretightning force state on the contrary, in the present embodiment,
When driving device 210 is greater than the pretightning force of spring to the power that wheel disc 231 applies, wheel disc 231 turns counterclockwise with ovable valve stem 100
Dynamic, idler wheel 310 is scrolled down through along guide groove 320 when rotated, moves downward valve rod 100, conversely, working as driving device 210
It, can be accurate by the cooperation of return unit 233 and driving device 210 when being less than the pretightning force of spring to the power that wheel disc 231 applies
Ground controls the up and down of valve rod 100.
Referring to Fig. 2, there are two connecting rod 234 can set, and the two sides of valve rod 100 are symmetrically located at, keep wheel disc 231 more flat
The area ovable valve stem 100 that weighs rotates, and further reduces the lateral force that valve rod 100 is subject to when up and down, correspondingly, idler wheel
310 also are provided with two, and are correspondingly connected with the two sides that bar 234 is symmetrically located at valve rod 100.
Further, the top of valve rod 100 is arranged with link block 340, and link block 340 is arranged along horizontal extension, and both ends
The corresponding rolling axis connection with two idler wheels 310, two connecting rods 234 can be inserted in link block 340 up and downly, make wheel disc
Connection between 231 and valve rod 100 is more stable and reliable.
The present invention also proposes a kind of exhaust gas recirculation valve, for controlling the waste gas circulation of engine, the exhaust gas recycling
Valve includes above-mentioned valve rod driving mechanism, accurately controls the exhausted air quantity into engine, and then reduce the discharge of NOx.
The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all at this
Under the inventive concept of invention, using equivalent structure transformation made by description of the invention and accompanying drawing content, or directly/use indirectly
It is included in other related technical areas in scope of patent protection of the invention.
