Description
Technical field
The present invention relates to a kind of propelling unit saddle, especially a kind of compact guide frame for ship propeller that can be applied to main thruster, thruster and all-direction propeller belongs to the marine propulsion field.
Background technology
Saddle is as the crucial roll adjustment part in the adjustable pitch propulsion system, and the quality of its performance will directly affect the propulsion coefficient of screw propeller.Saddle, the propeller hub body, blade packing and slide block have formed the distance adjustor in the adjustable pitch propulsion system jointly, existing distance adjustor, as shown in Figure 1, the oval ring that saddle is generally linked to each other by order, blade pitch adjustment district and short annulus consist of, wherein, oval ring forms positive car oil pocket after being connected with cylinder seal by piston, and short annulus forms the reversing oil pocket after being connected with stern shaft seal, be equipped with a boss (being equivalent to slide block) on four surfaces of square part, offer the chute corresponding with boss on the blade packing, hence one can see that, and this structure has following shortcoming:
1, because all there is a small boss on four surfaces in saddle blade pitch adjustment district, therefore, part shape is very irregular, two ends are long, middle wide, consider stock utilization, saddle can only be used foundry goods, and foundry goods tends to occur more scabrous foundry defect in foundry production, such as: pore, scab, burning into sand etc.
2, in this distance adjustor, piston and saddle adopt the separation type structure, namely be directed to saddle and be equipped with special piston, it adopts bolt piston to be fastened on the left end of saddle, then the pressure oil pushing piston drives together straight-line motion of saddle, and then by placing the boss in the blade packing chute, realize rotatablely moving of blade, regulated the pitch of blade.This structure, all higher to the processing request of saddle, piston and oil cylinder, otherwise can cause sealing effectiveness bad; Tie bolt between piston and the saddle will bear very large power in work, it is had higher requirement of strength, if there is problem, repairs just very difficultly, and risk is also larger.
3, for making positive car oil pocket can be full of pressure oil, then need to transport pipe be installed in the piston sealing, therefore, the neither facility of oil pipe installation, maintenance.
4, the propeller structure of this structure is comparatively huge.
5, saddle is wholely set the spacing step, and therefore, the stroke of this distance adjustor saddle is certain, can only be used for specific blade pitch control, does not have universality.
Summary of the invention
The present invention is directed to and adopt the foundry goods saddle to produce easily foundry defect, separation type piston and saddle processing request height in the prior art, a kind of compact guide frame for ship propeller is provided, this saddle has piston function concurrently, the spacing step of separation type is installed at saddle simultaneously, can by changing this spacing step, realize the stroke adjustment of saddle.
For realizing above technical purpose, the present invention will take following technical scheme:
A kind of compact guide frame for ship propeller, comprise cage body, this cage body is offered inner chamber along axis, and cage body comprises oval ring, blade pitch adjustment district and short annulus that order links to each other, periphery next-door neighbour's blade pitch adjustment district's socket annular distance parts of described oval ring; The outer rim in described blade pitch adjustment district is the regular prism setting, L shaped groove is all offered in each side of this regular prism, described L shaped groove comprises guide groove and the chute of perforation, described guide groove parallels with the axis of saddle, the notch of guide groove arranges towards oval ring end face simultaneously, chute is then perpendicular with the axis of saddle, and square shallow slot is offered at the corresponding position of each bar incline of described regular prism, and the bottom land of this square shallow slot is provided with tapped bore; Described inner chamber is disposed radially for the dividing plate that oil pipe is installed, and the oil transportation hole is offered at the middle part of dividing plate; The periphery of oval ring and propeller hub liquid sealing are connected to form front oil pocket, and periphery and the propelling unit stern tube shaft liquid sealing of short annulus are connected to form rear oil pocket.
The ringwise flange setting of described dividing plate, and the inner chamber between annular lip and the oval ring end face is the back taper setting.
Described annular lip is the uniform threaded mounting hole that is used for installing oil cylinder more than three circumferentially.
Each crest line of described regular prism all passes through chamfered.
The inner circle equal diameters of the outside diameter of described oval ring and short annulus.
Described oil transportation hole is stepped through hole.
According to above technical scheme, to compare with saddle habitual in the prior art, saddle of the present invention has the following advantages:
1, the present invention is at the peripheral annular distance parts of installing of oval ring in next-door neighbour's blade pitch adjustment district, therefore, compare with the spacing step of saddle integrally casting in the prior art, the present invention can be by changing the annular distance parts of different size, realize the adjusting of the different strokes of saddle, can realize that namely the maximum of blade is adjusted angle;
2, the present invention is regular prism with the outer rim setting in blade pitch adjustment district, and all offer L shaped groove in each side of regular prism, be used for installing the slide block of distance adjustor, this L shaped groove comprises guide groove and chute, guide groove is convenient to the installation of slide block, the moving range of chute restriction slide block, therefore, with in the saddle outer rim boss is set in the prior art and compares, the more regular compactness of global shape of the present invention, stock utilization can be higher so that saddle adopt forging or foundry goods can, so namely saved cost and reduced again the possibility that defective appears in the saddle raw MAT'L;
3, the present invention is connected to form an oil pocket with periphery and the propeller hub liquid sealing of oval ring, periphery and the propelling unit output shaft liquid sealing of short annulus are connected to form another oil pocket, therefore, by the annular lip sealing that arranges at the saddle inner chamber inner oil tube is installed, thereby the saddle inner chamber is separated into two chambers, saddle has had the function of piston, do not need to arrange separately piston, structure is very compact, has reduced number of parts, reduce processing request, improved the security of system reliability.
4, the present invention offers square shallow slot at the corresponding position of each incline of regular prism, and offer tapped bore at the bottom land of this square shallow slot, so that copper sheet to be installed, resistance to abrasion when the raising saddle contacts with propeller hub body inwall is (when propeller hub is installed, general and the propeller hub body inwall close contact of the incline in the blade pitch adjustment district of saddle, during traveling priority, very easily cause the wearing and tearing of blade pitch adjustment district before and after the saddle), the service life of namely effectively having improved saddle.
5, the present invention so that the oil pressure bearing surface of front chamber and rear chamber is basically identical, has guaranteed the stable circulation of pressure oil in front chamber and the rear chamber with the isometrical setting of interior circular diameter of outside diameter with the short annulus of oval ring effectively.
