Brief description of the drawings
Fig. 1 is the schematic diagram of the movement conversion mechanism provided by the present invention for direct torque.
Specific embodiment
Below, substantive distinguishing features of the invention and advantage are further described with reference to example, but the present invention not office
It is limited to listed embodiment.
As shown in figure 1, a kind of movement conversion mechanism for direct torque, including the torque axis 1 that moves up and down and with
The torque crank 2 that can be moved and being rotated with torque axis 1 of the connection of the torque axis 1, the torque crank 2 connects rack machine
Structure 3 simultaneously can make the rackwork 3 for linear motion by rotation, the rackwork 3 and the torque gear 4 of linear motion
Engagement can be rotated the correspondence of torque gear 4, wherein the outer surface of upper of the torque axis 1 is provided with annular groove 11, institute
State torque crank 2 have torque axis embedded division 22 in the insertion annular groove 11 and with stir the straight line of the rackwork 3
Mobile tooth bar pushing section 23, the torque axis embedded division 22 is relative with tooth bar pushing section 23 to be located at and torque crank support shaft 20
On the contiguous block 21 of connection.
Wherein, the rackwork 3 includes baseplate part 30, and the side of the baseplate part 30 is provided with tooth-strip part 31, for institute
The gear engagement connection on torque gear 4 is stated, the opposite side of the baseplate part 30 has the tooth bar pushing section with the torque crank
The 23 crank pushing sections being engaged.
Implement, the crank pushing section includes two L-shaped connectors 32, two L-shaped connector intervals set
Put, centre is formed with the insertion space of the insertion of tooth bar pushing section 23 for the torque crank 2, the insertion of tooth bar pushing section 23 institute
After stating insertion space, the corresponding L-shaped connector 32 can be stirred by the rotation of the tooth bar pushing section 23, so that tooth
Bar mechanism 3 moves linearly back and forth, so as to be engaged with torque gear 4, makes torque gear 4 clockwise or counterclockwise.
The connection torque of torque gear 4 gear shaft 41, by the rotation of the torque gear 4, can synchronously drive institute
Torque gear shaft 41 is stated to rotate, so that realize driving the revolving part being connected with the torque gear shaft to be rotated, so as to realize
The up and down motion of torque axis 1 is make use of, the work(for being rotated corresponding with the revolving part that the torque gear shaft is connected is realized
Energy and purpose.
Wherein, the torque axis 1 can be vertically arranged, and the level of torque crank support shaft 20 of the torque crank 2 sets
Put, the axis perpendicular with torque axis 1, the torque gear shaft is vertically arranged, and diameter parallel with torque axis 1 and staggering sets
Put, the rackwork 3 can be horizontally disposed with.
When torque axis 1 is moved upwards, rotate counterclockwise fortune can be done around the line of torque crank support shaft 20 with dynamic torque crank 2
Dynamic, torque crank 2 drives rackwork 3 to move along a straight line, and rackwork 3 is engaged with torque gear 4, makes torque gear 4 around it
Axis does clockwise rotation.When torque axis 1 is moved downward, principle is identical, and the direction of motion is conversely, the direction of motion such as Fig. 1
Shown in middle arrow.
Relative tertiary location by converting each part of the invention, when can also realize that torque axis 1 is moved upwards, torque gear
4 do counter-clockwise rotary motion, and when torque axis 1 is moved downward, torque gear 4 does clockwise movement, and its principle is identical.
When torque of valve electric device control is applied particularly to, the torque crank support shaft 20 can be installed by bearing
In the housing sidewall of mechanism, the rackwork 3 is installed in the housing and is provided with support member to support in the bottom of baseplate part 30
Rackwork 3, the torque axis 1 can be used as outside rotating control shaft, dynamic endless screw apparatus such as be connected, installed in mechanism
In housing, the torque gear shaft 41 connects the revolving part to be driven, the microswitch that such as controlled motor works, so by turning
The elevating movement of square axle 1, it is possible to achieve the rotation of control microswitch, so as to control the motor switch of executing agency.
The present invention can be used for the direct torque of electric device for valve for the movement conversion mechanism of direct torque, itself and spiral shell
Rotation mechanism is different, employs crank block and rack-driving principle, efficiency high and requirement on machining accuracy is low, is asked in the absence of self-locking
Topic, and linear motion can be converted to the rotary motion of space any direction.
It should be noted that the movement conversion mechanism for direct torque of the present invention, may not only be applied to electric valve
The direct torque of device, it is also possible in the middle of the mechanism for being converted to Space Rotating motion of entering to be about to for any need to move along a straight line
Go, be particularly suitable for that reciprocating linear line moving displacement amount is small, while requiring the big occasion of the rotary motion angle range of output.
Relative position by adjusting torque crank of the invention, can easily realize the straight line fortune that will change compared with thin tail sheep
The rotary motion of the dynamic relatively big corner change be converted on any direction of space, is easy to the torque of electric device for valve to adjust.
The present invention can according to the difference of the relative tertiary location of each part, when realizing that torque axis does upward linear motion,
Torque gear does the clockwise rotation on any direction of space, when corresponding torque axis does downward linear motion, turns
Square gear does the counter-clockwise rotary motion on any direction of space.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
