Embodiment
For example the present invention is described in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1～3, it mainly comprises input gear 5, output gear 3, Control Shaft 13, hydraulic fluid chamber, Control Shaft helical tooth 4, hydraulic pressure oilhole, hydraulic fluid chamber housing, three position four-way electromagnetic valve 10 and controller 15 the present invention.In controller 15, set the phase place advance angle of needed output gear 3 relative input gears 5.The position signal of Control Shaft 13 is transferred to controller 15 by position transducer 14, and in controller 15, process calculates real-time phase advance angle.In the time that real-time phase advance angle is greater than the phase place advance angle of setting, error amount is for just, and three position four-way electromagnetic valve 10 is placed in left position by controller 15, oil inlet pipe 12 and right-hand member hydraulic oil pipe are communicated with, return tube 11 and left end hydraulic oil pipe are communicated with, and Control Shaft 13 moves to right, and phase place advance angle reduces; In the time that real-time phase advance angle is less than setting setting value, error amount is for negative, and three position four-way electromagnetic valve 10 is placed in right position by controller 15, oil inlet pipe 12 and left end hydraulic oil pipe are communicated with, return tube 11 and right-hand member hydraulic oil pipe are communicated with, and Control Shaft 13 moves to left, and phase place advance angle increases; In the time that real-time phase advance angle equals setting value, error amount is zero, and three position four-way electromagnetic valve 10 is placed in meta by controller 15, left end hydraulic oil pipe and the sealing of right-hand member hydraulic oil pipe, and Control Shaft 13 does not move axially, and phase place advance angle remains unchanged.Because Control Shaft 13 can be controlled in any axial position in moving range, and be continuous action while moving axially, so device can be realized step-less adjustment phase place advance angle, and controlling method is also very simple.
Input end hydraulic fluid chamber 7 housings are at the right-hand member of Control Shaft 13, and Control Shaft 13 precision-fit.Input out end hydraulic pressure oilhole 8 and input out end hydraulic fluid chamber housing 6 right left ends, be communicated with and input out end hydraulic oil pipe 9 and input out end hydraulic fluid chamber 7.Three position four-way electromagnetic valve 10 is arranged in to be inputted out between end hydraulic oil pipe 9 and oil inlet pipe 12.Input gear 5 is arranged on the right-hand member of Control Shaft 13, but at the left end of input end hydraulic fluid chamber housing 6.Position transducer 14 is between input gear 5 and output hydraulic pressure oil pocket housing 17.Output terminal hydraulic fluid chamber housing 17 is divided into two-part, lays respectively at output gear 3 both sides, to output gear 3 axial constraints.Output gear 3 is arranged on the left end of Control Shaft 13, and helical tooth 4 on Control Shaft 13 engages.
Concrete principle is as follows:
If conceivable maximum phase corner is Ψ
max13 mobile maximum displacements of Control Shaft are S
max, determine the pitch L of helical tooth 4 according to maximum variable phase place advance angle, formula is as follows:
In formula, Ψ
max---maximum phase corner, unit is °;
S
max---13 mobile maximum displacements of Control Shaft, the mm of unit;
The pitch of L---helical tooth 4, unit is mm
Pitch L is linear correlation between the displacement S that phase rotator Ψ and Control Shaft 13 move after determining, therefore can change phase rotator Ψ between input gear 5 and output gear 3 relation between the two and is by changing the Control Shaft 13 displacement S that move:
The position of Control Shaft 13 is realized by controlling solenoid valve 10 by controller 15.When solenoid valve 10 is in left when position, hydraulic oil will enter output terminal hydraulic fluid chamber 2 through output terminal hydraulic oil pipe 16, in input end hydraulic fluid chamber 7, hydraulic oil can be released through return tube 11 simultaneously, Control Shaft 13 moves right, if helical tooth 4 rotation directions as shown in Figure 1, suppose to be seen from input end toward output terminal that it is clockwise direction that gear rotates, the phase place advance angle of output gear 3 will increase; When solenoid valve 10 is in right when position, identical with above-mentioned principle, Control Shaft 13 is moved to the left, and the phase place advance angle of output gear 3 will reduce.The Control Shaft monitoring 13 position informations are transferred to controller 15 by position transducer 14, draw real-time phase advance angle through computing, and target phase advance angle compares, in the time that both are equal, solenoid valve 10, in meta, seals input end hydraulic oil pipe 9 and output terminal hydraulic oil pipe 16.
First in controller 15, set needed phase place advance angle, the signal of position transducer 14 controller that is transferred to 15 is converted into real-time phase advance angle signal, and both relatively produce error in controller 15.Suppose to be seen from input end toward output terminal that it is clockwise direction that gear rotates, in the time that real-time phase advance angle is less than the phase place advance angle of setting, error amount is for negative, controller 15 is present position in Fig. 1 by three position four-way electromagnetic valve 10 in left position, oil inlet pipe 12 and output terminal hydraulic oil pipe 16 are communicated with, return tube 11 and input end hydraulic oil pipe 9 are communicated with, and the hydraulic oil in output terminal hydraulic fluid chamber 2 promotes Control Shaft 13 and moves right.Known according to the relation between displacement and phase place advance angle, it is large that phase place advance angle becomes.In the time that actual phase advance angle is greater than the phase place advance angle of setting, error amount is for just, controller 15 by three position four-way electromagnetic valve 10 in right position, oil inlet pipe 12 and input end hydraulic oil pipe 9 are communicated with, return tube 11 and output terminal hydraulic oil pipe 16 are communicated with, hydraulic oil in input end hydraulic fluid chamber 7 promotes Control Shaft 13 and is moved to the left, and phase place advance angle diminishes.In the time that actual phase advance angle equals the phase place advance angle of setting, error amount is zero, and controller 15 is by three position four-way electromagnetic valve 10 in meta, and input end hydraulic pressure cavity 9 and output terminal hydraulic pressure cavity 16 are all closed, and Control Shaft 13 does not move axially.Due to the control that can realize Control Shaft 13 arbitrary positions, and control procedure is all continuous action, and therefore phase place advance angle adjustment process is stepless adjustment process.
The mechanical device of a kind of step-less adjustment phase place of the present invention advance angle, the critical piece of realizing step-less adjustment phase place comprises: Control Shaft, input gear, output gear, Control Shaft helical tooth, position transducer, solenoid valve, controller.
Control Shaft is subject to the control of two ends hydraulic oil, can move left and right, can rotate again simultaneously, the two ends of axle all with hydraulic fluid chamber precision-fit, to realize the sealing to hydraulic oil.The output terminal of Control Shaft has helical tooth, it and the inner engagement driving of output gear.The input end of Control Shaft is provided with input gear, by key transmission.
Input gear and outer gear engagement driving, and drive Control Shaft synchronously to rotate by key, its length must meet that Control Shaft moves left and right Shi Junneng preferably and outer gear engages.All equate with the output gear number of teeth, rotating speed.
Output gear inside has the spiral chute being meshed with Control Shaft helical tooth, and outside has the gear teeth, is subject to the constraint of output terminal hydraulic fluid chamber housing, and in the time that Control Shaft moves left and right, the relative hydraulic fluid chamber housing of output gear does not move left and right.Control Shaft helical tooth rotates output gear by engagement, and the position that hydraulic fluid chamber housing contacts with output gear is more smooth, and frictional force must be enough little.
Control Shaft helical tooth is distributed in Control Shaft surface, and the transmission that is meshed of output gear internal helicoid groove.
Position transducer is converted into electrical signal by the axial displacement of Control Shaft and passes to controller.
Solenoid valve is three position four-way electromagnetic valve, by controller control, in the time of left position, is communicated with input end hydraulic oil pipe and oil inlet pipe, is communicated with output terminal hydraulic oil pipe and return tube simultaneously; In the time of right position, be communicated with input end hydraulic oil pipe and return tube, be communicated with output terminal hydraulic oil pipe and oil inlet pipe simultaneously; In the time of meta, sealing input end hydraulic oil pipe and output terminal hydraulic oil pipe.
The Control Shaft position information that controller transmits according to position transducer, calculate the phase place advance angle between input gear and output gear, and compare with the phase place advance angle of setting in controller, according to error between the two, adjust Control Shaft position by controlling solenoid valve, finally make it be stabilized in desired location.
