These two branches are all driven by the first connecting lever 2, make respectively motion in slideway 10 and 14 of slide block 9 and 13.
Slideway 10 and 14 can play the effect that sliding trajectory limits to slide block 9 and 13, and slideway 10 and 14 can be straight line or the curve of realizing the special exercise track.
Be provided with connecting pin 3,17,21,12,15,19,6 and 8 in this double glide transmission mechanism, its objective is and guarantee that mutual disengaging does not occur two moving components that are connected, and can produce relative rotation between two moving components guaranteeing to be connected.Wherein the first connecting pin 3 connects the first connecting lever 2 and first connecting rod 4; The second connecting pin 17 connects first connecting rod 4 and the second connecting lever 20; The 3rd connecting pin 21 connects the second connecting lever 20 and second connecting rod 11; The 4th connecting pin 12 connects second connecting rod 11 and the first slide block 13; The 5th connecting pin 15 connects the first connecting lever 2 and third connecting rod 16; The 6th connecting pin 19 connects third connecting rod 16 and the 3rd connecting lever 5; The 7th connecting pin 6 connects the 3rd connecting lever 5 and the 4th connecting rod 7; The 8th connecting pin 8 connects the 4th connecting rod 7 and the second slide block 9;
The motion mode of first slippage transmission branch is as follows: the first connecting lever 2 and rotation support shaft 1 are together around the central rotation that rotates back shaft 1, by the first connecting pin 3, first connecting rod 4 and the second connecting pin 17, drive the second connecting lever 20 around 18 rotations of fixed support axle; By the 3rd connecting pin 21, second connecting rod 11, the 4th connecting pin 12, the first slide block 13 is moved along the first slideway 14 again.
The motion mode of second slippage transmission branch is as follows: the first connecting lever 2 and rotation support shaft 1 are together around the central rotation that rotates back shaft 1, by the 5th connecting pin 15, third connecting rod 16 and the 6th connecting pin 19, drive the 3rd connecting lever 5 around 18 rotations of fixed support axle; By the 7th connecting pin 6, the 4th connecting rod 7 and the 8th connecting pin 8, the second slide block 2 is moved along the second slideway 14 again.
In original position (as shown in Figure 1), the line of centres angle of the line of centres of rotation support shaft 1, the 5th connecting pin 15 and the 5th connecting pin 15, the 6th connecting pin 19 is in 170 ° to 190 ° scopes; The line of centres angle of the line of centres of fixed support axle 18, the 7th connecting pin 6 and the 7th connecting pin 6, the 8th connecting pin 8 is in 170 ° to 190 ° scopes.Like this in original position when the first connecting lever 2 rotates a low-angle, the second slide block 9 only produces very small movement.
In the final position (as shown in Figure 2), the line of centres angle of the line of centres of rotation support shaft 1, the first connecting pin 3 and the first connecting pin 3, the second connecting pin 17 is in 165 ° to 195 ° scopes; The line of centres angle of the line of centres of fixed support axle 18, the 3rd connecting pin 21 and the 3rd connecting pin 21, the 4th connecting pin 12 is in ± 10 ° of scopes.In the final position, when the first connecting lever 2 rotated a low-angle, the first slide block 13 only produced very small movement like this.
When the first connecting lever 2 when being similar to angular displacement shown in Figure 5 and turning clockwise, the speed of two slide blocks can be divided into three sections:
The A section: by the second slide block 9 setting in motion speed are very little as can be known, the first slide block 13 is Accelerating running (such as the A section among Fig. 6) then.
The B section: after the first connecting lever 2 turned to certain angle, the second slide block 9 began to accelerate mobile; In the second slide block 9 accelerated motion processes, the first slide block 13 reduces speed now, and the momentum that the first slide block 13 slows down generation will help the second slide block 9 to accelerate (such as the B section among Fig. 6).
The C section: through after the B section, the first slide block 13 will continue to slow down until zero, and slow than the B section in this section the first slide block 13 deceleration trend; The second slide block 9 also will slow down, and will be decelerated to zero (such as the C section among Fig. 6) when the final position.
When the first connecting lever 2 clockwise directions rotate near the final position (final position as shown in Figure 2), by as can be known above-mentioned, speed will be close to zero near the final position time for the first slide block 13, and therefore the first slide block 13 does not need buffering, only needs buffering the second slide block 9 to get final product.
When being rotated counterclockwise to original position, incipient stage the first slide block 13 movement velocitys are very little, the second slide block 9 quick slidings from the final position by " accelerate-more at the uniform velocity-at last being decelerated to first zero " when the first connecting lever 2; The second slide block 9 slows down afterwards, and when the second slide block 9 was decelerated to zero, the first slide block 13 was near maximum speed, and the momentum that the second slide block 9 slows down generation will help the first slide block 13 to accelerate; Again, by as can be known aforesaid, atomic little movement will occur in the second slide block 9, and the first slide block 13 also will slow down, and therefore when the buffering of this mechanism is set, only need buffering the first slide block 13. Slide block 9 and 13 movement velocity characteristic are as shown in Figure 7 in this case.
In whole motion process, make the 4th connecting rod 7 and the second slideway 10,14 one-tenth one angle less than 10 degree of second connecting rod 11 and the first slideway, can reduce the friction of slide block and slideway like this, thereby make the slide block smooth slippage.
Can be by regulating the dimensional parameters of drive disk assembly in this double glide transmission mechanism, make the second slide block 9 have different slide displacements and sliding speed with the first slide block 13, a kind of simple and effective control method is: by changing the line L that rotates the strong point and the 7th connecting pin 6 in the 3rd connecting lever 5
18,6Length, or change L in the 3rd connecting lever 5
18,6With L
18,19Angle, can make the second slide block 9 have speed and the displacement of satisfying the demand; Same, by changing L in the second connecting lever 20
18,21Length, or change L in the 3rd connecting lever 5
18,17With L
18,21Angle, also can make the first slide block 13 have speed and the displacement of satisfying the demand.
Fig. 8 and 9 is embodiment of contact transmission mechanism in the circuit breaker, the double glide mechanism that this transmission mechanism has adopted the present invention to propose.Except running part, it comprises that also an arc of motion contact 33(is equivalent to the second slide block 9), the first guide holder 28, the second guide holder 30, gear frame 22, guide post 23, the 3rd guide holder 24, motion main contact 26, the first static main contact 25, the second static main contact 27, arc control device 29, static arcing contact 31 and tail bearing 32.Rotation support shaft 1 and fixed support axle 18 are separately fixed on the case for circuit breaker.
Common guiding the second slideways 10 that form of the first guide holder 28 and the second guide holder 30 are equivalent to the second slide block 9 to arc of motion contact 33() lead, make the arc of motion contact 33 can only traveling priority.Gear frame 22, guide post 23 and motion main contact 26 adopt integral body of the fixing formation of mode of mechanical connection, be equivalent to the first slide block 13 among Fig. 1 and 2, be provided with guiding the first slideway 14 on the 3rd guide holder 24, it is by 2 guiding, and the integral body that gear frame 22, guide post 23 and motion main contact 26 are formed can only traveling priority.Arc of motion contact 33 links to each other with the 4th connecting rod 7 by connecting pin 8, and gear frame 22 links to each other with second connecting rod 11 by the 4th connecting pin 12.
Fig. 8 is the breaker closing state, at this moment, because arc of motion contact 33 resistance are large, so electric current flow through successively tail bearing 32, the second static main contact 27, motion main contact 26, the first static main contact 25, the 3rd guide holder 24.When the first connecting lever 2 turns clockwise to terminal the position from original position by angular displacement shown in Figure 5, at first by the first connecting pin 3, first connecting rod 4 and the second connecting pin 17, drive the second connecting lever 20 and turn clockwise around fixed support axle 18; By the 3rd connecting pin 21, second connecting rod 11, the 4th connecting pin 12, gear frame 22, guide post 23 and motion main contact 26 are accelerated towards the direction slippage away from the second static main contact 27 under the effect of guiding the first slideway 14 again.And this moment, because the center of fixed support axle 1, the 5th connecting pin 15, the 6th connecting pin 19 is in the position close to conllinear, and the center of rotation support shaft 18, the 7th connecting pin 6, the 8th connecting pin 8 is also in the position close to conllinear, so arc of motion contact 33 movement velocitys are very little.
After motion main contact 26 breaks away from the second static main contact 27, electric current will flow through successively tail bearing 32, static arcing contact 31, arc of motion contact 33, the second guide holder 30, the 3rd guide holder 24.Within a period of time after this, arc of motion contact 33 will speed up court and moves away from static arcing contact 31 directions, and during this period of time, motion main contact 26 will slow down, and the momentum of this deceleration will help arc of motion contact 33 to accelerate.After arc of motion contact 33 breaks away from static arcing contact 31, will between the two, produce electric arc, under the effect of arc control device 29 interior arc-extinguishing mediums, electric arc extinguishes in 10 ~ 20 milliseconds after the starting the arc.
When the first connecting lever 2 during near the final position, the first connecting lever 2 will slow down (as shown in Figure 5), and the center of fixed support axle 1, the first connecting pin 3, the second connecting pin 17 is in the position close to conllinear; The center of fixed support axle 18, the 3rd connecting pin 21, the 4th connecting pin 12 is also in the position close to conllinear, therefore the movement velocity of gear frame 22, guide post 23 and motion main contact 26 will be very little, be that gear frame 22, guide post 23 and motion main contact 26 do not need buffering, therefore only need kicking motion arcing contact 33 both can, like this, when transmission mechanism was reached home the position, the speed of all moving components all was zero.
