Description

A kind of tuning for Controllable Pitch Propeller oil distributor with linear feedback
Technical field
The present invention relates to a kind of oil distributor with linear feedback for controllable pitch propeller hydraulic power system, especially a kind of two-way oil circuit locking for controllable pitch propeller and there is the oil distributor with linear feedback of lubricated propeller hub system.
Background technology
Oil distributor is the core in hydraulic power system, is applied to controllable pitch propeller hydraulic power system.As shown in Figure 1, it comprises rotor 1, connecting panel 2, stator 3, housing 4, oil connector 5, transparent cover 6, sealing 7, feedback rod 8 etc. to existing oil distributor; Because of gapped between stator and rotor, after pitch adjustment finishes, high pressure oil in oil cylinder can leak from stator and rotor clearance, under moment loading, can reduce or augment direction motion to pitch angle outside, at this moment electric-control system detects the variation of pitch angle, and opening controlling valve is withdrawn into instruction pitch angle position blade, so repeatedly, there is the problem that pitch angle hunting frequency is high; Moreover, in navigation process, there is hydraulic system fault, with regard to there will be pitch angle to change along with the effect of moment of face, affect route speed, serious also can affect safety of navigation.
Existing oil distributor is provided with draining oil circuit, and propeller hub channel for oiling is not set, cannot be directly lubricated to propeller hub from oil distributor fuel feeding, and can only rely on other approach to solve, certainly will increase like this equipment cost, and operating cost.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and a kind of two-way oil circuit locking of novel controllable pitch propeller is provided and there is the tuning for Controllable Pitch Propeller oil distributor with linear feedback of lubricated propeller hub system.
The object of the invention is to complete by following technical solution, it comprises the outer oil pipe of gear case, feedback rod, rotor, connecting panel, housing, stator, High-pressure oil sealing, hydraulic control one-way valve, pitch feedback mechanism, described rotor and gearbox output shaft rigid attachment, connecting panel and gearbox output shaft front bearing cap rigid attachment, rotor front end is provided with two hydraulic control one-way valves, being provided with A oil inlet and B oil inlet oil pipe outside the mesopore of hydraulic control one-way valve separately and feedback rod and gear case communicates respectively, described feedback rod is connected with one end that one end is fixed on the inner oil tube on oil cylinder piston, this feedback rod is connected with the feedback frame in pitch feedback mechanism, on feedback frame, be provided with the pointer that can show current pitch angle, and be sent to connected command and control system by linear pitch sensor.
Between described stator and rotor, have small gap, and described stator two ends are provided with the High-pressure oil sealing sealing, described A oil inlet and B oil inlet form and have the oil circuit of leakage and form and have channel for oiling through rotor through stator, this leaks that oil circuit is connected with propeller hub body through oar axle mesopore with channel for oiling and lubricated propeller hub mechanism, and described leakage oil circuit and channel for oiling are also connected with the drain tap C that unnecessary oil can be back to power fuel tank.
Stator of the present invention and rotor have small gap, rotor and gearbox output shaft rigid attachment, connecting panel and gearbox output shaft front bearing cap rigid attachment.High-pressure work oil content, not from A, B mouth oil pipe through hydraulic control one-way valve enters into feedback rod mesopore and gear case, enters chamber, oil cylinder front and back by oil pipe inside and outside screw propeller, and promote piston and move, thus the ahead running of control and reversing.Because inner oil tube one end is fixed on piston, so also motion thereupon of inner oil tube; And the inner oil tube other end is connected with feedback rod, when inner oil tube seesaws, the feedback frame in pitch feedback mechanism is motion thereupon also, and the pointer on feedback frame just can show current pitch angle, and is sent to command and control system by linear pitch sensor.
Owing to having minim gap and the high pressure rotary sealing effect of stator two ends between stator and rotor, A, B mouth leakage of oil leak oil circuit and rotor lubrication oil circuit through stator, through oar axle mesopore, are connected with propeller hub body, lubricate propeller hub mechanism, another side, unnecessary oil is got back to power fuel tank by drain tap C.
Because rotor front end arranges two hydraulic control one-way valves, after roll adjustment finishes, with regard to locking two-way oil circuit, because hydraulic oil is incompressible, even under larger blade resultant moment effect, also can make pitch be stabilized in the location of instruction, can eliminate existing tuning for Controllable Pitch Propeller and produce the high defect of pitch angle hunting frequency, guarantee that propelling unit drive ability is good, eliminate the hidden danger that main frame may overload, reduce the wearing and tearing of each motion assembly of distance adjustor, the service life of extension device simultaneously.Moreover run into hydraulic system fault in navigation way, and because of being provided with hydraulic control one-way valve, pinned oil circuit, just can avoid the effect of pitch moment of face and change assurance safe navigation.
The present invention integrates oil distributor and feedback mechanism, and sensor to change rotating detector be linear pitch sensor, alleviated the weight of feedback mechanism, improved the safe reliability of feedback mechanism.
Accompanying drawing explanation
Fig. 1 is existing oil distributor structural representation
Fig. 2 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.Shown in Fig. 2, the present invention mainly comprises the outer oil pipe 1 of gear case, feedback rod 2, rotor 3, connecting panel 4, housing 5, stator 6, hydraulic control one-way valve 7, oil connector 8, High-pressure oil sealing 9, pitch feedback mechanism 10, hydraulic control one-way valve 11.Described rotor 3 and gearbox output shaft rigid attachment, connecting panel 4 and gearbox output shaft front bearing cap rigid attachment, rotor 3 front ends are provided with two hydraulic control one-way valves 11,7, and the hydraulic control one-way valve that this rotor front end is installed is screw thread screw-in hydraulic control one-way valve; Being provided with A oil inlet and B oil inlet oil pipe 1 outside the mesopore of hydraulic control one-way valve 11,7 separately and feedback rod and gear case communicates respectively, described feedback rod 2 is connected with one end that one end is fixed on the inner oil tube on oil cylinder piston, this feedback rod 2 is connected with the feedback frame in pitch feedback mechanism 10, on feedback frame, be provided with the pointer that can show current pitch angle, and be sent to connected command and control system by linear pitch sensor.
