The specific embodiment
Accompanying drawing discloses concrete structure of the present utility model without limitation, and the utility model will be further described below in conjunction with accompanying drawing.
As seen from Figure 1: be provided with in the support 4 and join oil jacket 5, and be provided with and the flange 3 of joining oil jacket 5 concentrics at support 4 end faces, described inner and outer wall of joining oil jacket 5 is respectively equipped with inside and outside distribution oil ring groove, be provided with the oil circuit of communication between interior distribution oil ring groove and the outer distribution oil ring groove, support 4 is provided with outer oil circuit gangway 11, described outer oil circuit gangway 11 with join that outer distribution oil ring groove leads on the oil jacket 5, the other end of support 4 is the support annular seal space; Be set with revolving sleeve 2 on the inner oil tube 1, form outer oil circuit 12 between inner oil tube 1 outer wall and revolving sleeve 2 inwalls; Inner oil tube 1 and revolving sleeve 2 inserts flanges 3, joins oil jacket 5 and support 4, and with flange 3 with join oil jacket 5 concentrics, wherein: inner oil tube 1 end is passed flange 3 and joined oil jacket 5 and places the support annular seal space, and the support annular seal space is provided with inner oil tube gangway 13; Revolving sleeve 2 passes flange 3 and places and join oil jacket 5, outer oil circuit 12 with join on the oil jacket 5 in the distribution oil ring groove logical; Place support annular seal space inner oil tube 1 end to be provided with bearing 6 and bearing lining 7, with bearing lining 7 and circlip 10 locking bearings; Contain flange on revolving sleeve 2 outer walls.
In the present embodiment, join oil jacket 5 by pin and support 4 location; Flange 3 is provided with oil sealing 14 and oil sealing pressing plate 9 with revolving sleeve 2 joint portions, and oil sealing pressing plate 9 is by being bolted on the flange 3; The support capsule walls in inner oil tube 1 direction of insertion dead ahead is provided with the assembly technology hole, is furnished with stifle 8 on the assembly technology hole.Flange 3 and revolving sleeve 2 outer wall upper flanges in conjunction with being equipped with seal ring 15 in end face and the stifle, the revolving sleeve and the inner oil tube direct contact place that are positioned at outer oil circuit 12 ends are provided with seal ring 15, outer distribution oil ring groove both sides join oil jacket 5 outer walls and support 4 junctions are equipped with seal ring 15.Be provided with oilhole 16 in the revolving sleeve 2, be provided with oil return circuit 17 in the flange 3.During concrete enforcement, the oil distributor interface of standard is all adopted in inner oil tube gangway 13 on the support annular seal space and the outer oil circuit gangway 11 on the support.
During use, revolving sleeve 2 outer wall upper flanges are connected with gearbox output shaft, and flange 3 is connected by the casing of flange hole with the gear case mouth with after support 4 usefulness bolt are connected, and the potentiometer of feedback signal is located on the support 4.
Road pressure oil in the oil distributor enters the support annular seal space from inner oil tube gangway 13, sends into oil cylinder inner carrier one side by inner oil tube 1; Another road pressure oil by outer oil circuit gangway 11, join oil jacket 5 and enter outer oil circuit 12, arrive at the piston opposite side.During work, one road pressure oil is a fuel feeding, another Lu Zewei oil return, on the contrary another road pressure oil is a fuel feeding, and one the tunnel then is oil return, and the oil circuit of variation drives piston back-and-forth movement, drives slider-crank mechanism by piston and realizes the blade rotation.Simultaneously, because revolving sleeve 2 and join oil jacket 5 fitting surfaces and have certain clearance, understand in the flange cavity that some pressure oil is penetrated into oil sealing 14 places, and flow to tween drive shaft, stern tube shaft endoporus by the oilhole on the revolving sleeve 2 16, provide lubricated for in-to-in oil pipe and propeller hub, unnecessary oil mass flows back to the fuel tank of hydraulic efficiency pressure system from the oil return circuit of flange 3, realizes recycle.By inner oil tube 1, bearing 6 amount of piston displacement is fed back to potentiometer simultaneously, the horizontal displacement of pitch is converted into electric signal, obtain variable pitch and feedback information by potentiometer.
Different from existing oil distributor structure is: this structure is the original support chamber that just is used as feedback cavity Sealing, as one oil circuit and feedback cavity, joining oil jacket only provides another road oil circuit, replaces sliding with bearing Ring. Do so effective oil distributor space structure and the own wt of having reduced, reduced production cost. Be convenient to simultaneously install, and improve the compensation rate of revolving sleeve alignment error. Replace slip ring with bearing and become original Sliding friction be rolling friction, effectively increased the flat of service life of oil distributor and feedback signal Stability, and selected the transit joint of standard, be conducive to client's installation and replacing, also have simultaneously Effect avoided leakage problem into and out of hydraulic fluid port.
