Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
The closure of DC motor Driver, as shown in Figure 1, comprise the direct current generator 2 be fixed on by motor casing 1 on sensor 9, motor gear 3 is arranged on direct current generator 2, motor gear 3 is meshed with the gearwheel 5 of three driven gears 4, the small gear 6 of three driven gears 4 is meshed with transition gear 8, three driven gears 4 are uniformly arranged on sensor 9 (as shown in Figure 2) by gear shaft 7, transition gear 8 and valve rod 10 be an integral installation on valve body 11, valve block 12 is arranged on valve rod 10.
As shown in Figure 3, the chip 17 on sensor 9 is placed in directly over the magnet steel 18 on transition gear 8, and sensor 9 reads the position signal of the magnet steel 18 on transition gear 8 by the chip 17 of sensor 9, namely can read the aperture of valve block 12.
As shown in Figure 4, one end 14 of torsion spring 13 is connected on valve body 11, and after pretension, the other end 15 is arranged on banking stop 16, and banking stop 16 is arranged on valve rod 10.
As shown in Figure 4, valve block 12 is connected with banking stop 16 by valve rod 10, and be connected with valve body 11 after one end 14 pretension of torsion spring 13, the other end 15 is connected with banking stop 16, and under the effect of torsion spring pretightening force, valve block 12 is in normally open position.
As shown in Figure 1 and Figure 5, be energized to direct current generator 2, motor gear 3 rotates, motor gear 3 engages with the gearwheel 5 of three driven gears 4, drive driven gear 4 to rotate, the small gear 6 of driven gear 4 engages with transition gear 8, and transition gear 8 is connected as a single entity with valve rod 10 and valve block 12, moving valve plate 12 is with to rotate after the rotation of driven gear 4 overcomes torsion spring 13 moment, closed throttle.
As shown in Figure 4, when reducing the supply current of direct current generator 2, the moment of direct current generator 2 reduces, when moment be reduced to be less than spring torque time, valve block 12 reverses under the flywheel moment effect of torsion spring 13, and closure is opened.
When the supply current of direct current generator 2 is in a certain fixed value, the torsional moment of direct current generator 2 is equal with the torsional moment of torsion spring 13, and namely motor gear 3 stops the rotation, and throttle valve valve block 12 is stable at a certain aperture; Change the supply current of direct current generator 2, make it to reach new balance, thus throttle valve valve block 12 is stable at a certain new aperture; Namely the linearity control of closure is achieved.
The train of gearings of three kinds of gear compositions, its velocity ratio is fixing, thus ensure that the control accuracy of closure.
