Description
Technical field
The invention belongs to field of ship equipment, more particularly, to a kind of large ship based on split type cage structure
Propeller.
Background technique
Propeller hub component is the key position in propeller marine propuision system, saddle assembly be again in propeller hub component the most
Crucial stressed member, once ging wrong, the roll adjustment function of adjustable propeller will be unable to realize, huge loss will be caused to steamer,
In existing propeller hub component, general piston and saddle use separate type, and piston bolt fastening is pushed away in the left end of saddle, pressure oil
Then piston drives saddle to be moved linearly together.In this mechanism, general saddle is using whole single part, in processing ratio
It is more complex, while the connection bolt between piston and saddle will bear very big power at work, have to it higher strong
Degree requires, once a bolt goes wrong, due to discontinuity equalization, and then remaining bolt may be all broken again very much
Phenomenon brings risk to the safety of structure.When propeller hub model large size propeller hub, frame is also increased with it, single whole
Formula saddle not only forges inconvenience, and processes also inconvenience, there is a problem of manufacture inconvenience；Simultaneously when propeller hub model is big
When model propeller hub, the connection bolt of saddle and piston is difficult to select, and needs voluntarily nonstandard production bolt, brings the increase of cost,
Also the problems such as being unable to ensure the safety of bolt.
Summary of the invention
The purpose of the present invention is overcoming the above deficiency, a kind of large ship propulsion based on split type cage structure is provided
Device, not only forging with it is easy to process, but also saved cost；The connection of saddle and piston does not use bolt, uses piston spiral shell
Mother pre-tightens piston and saddle, while increasing saddle set part, is conducive to increase the pre- next deflection of piston unt, piston unt
Preload it is more safe and reliable.
To achieve the goals above, the present invention provides a kind of large ship propeller based on split type cage structure, packet
Propeller hub, the oil cylinder of propeller hub front end and the stern tube shaft of propeller hub rear end are included, inner oil tube and outer oil pipe are equipped in stern tube shaft, propeller hub is equipped with blade
Packing, blade packing connect blade and sliding block, saddle assembly are equipped in the propeller hub, and oil cylinder, saddle are inserted into saddle assembly front end
Stern tube shaft is inserted into component rear end；The saddle assembly is split type structure, including saddle axis, saddle set, saddle block and saddle ring, is led
Saddle set is cased with outside frame axis left end, saddle block is flexibly connected with sliding block, and saddle ring is fixedly connected with saddle set and saddle block respectively.
Piston is equipped in oil cylinder of the present invention, the chamber between the front end and cylinder body inwall of piston is rear chamber；Piston
Chamber between rear end and propeller hub is front chamber, and piston is mounted on saddle axis front end by piston unt.The piston unt is logical
It crosses nut latch to fix with piston, prevents nut from rotating.Oilhole is equipped in the piston.
Inner oil tube and rear chamber's connection in stern tube shaft of the present invention；Outer oil pipe is by the oilhole of saddle axis and piston with before
Chamber connection, the left part of the right end insertion stern tube shaft of saddle axis.
The outer diameter of saddle axis of the present invention left end is less than the outer diameter of saddle axis right end.
Saddle block of the present invention is tetragonal body block, and saddle root tuber portion is provided with offset distance pin, and offset distance pin is inserted into sliding block and realizes
It is flexibly connected, the blade packing is fixedly connected with blade by blade root screw.
Propeller hub of the present invention is bolted with oil cylinder, and propeller hub is connect with stern tube shaft by flange screw.
When in use, when hydraulic oil enters front chamber by outer oil pipe, saddle block is moved downward, and the hydraulic oil of rear chamber is logical
Inner oil tube is crossed to be recycled back into；When hydraulic oil enters rear chamber by inner oil tube, saddle block is pushed to move right, the liquid of front chamber
Pressure oil is recycled back by outer oil pipe.When saddle block is for linear motion, saddle root tuber portion is provided with offset distance pin, pin insertion sliding block
It realizes and is flexibly connected, sliding slot, the pin on saddle block and the sliding block three of blade packing form a tangent mechanism, drive fan disk
Root rotation.Since blade is fixedly connected with blade packing by blade root screw, the rotation of blade packing just changes the angle of blade
Degree, realizes the rotation roll adjustment of blade.
Compared with prior art, the invention has the benefit that
(1) saddle in the present invention adopts a split structure, and saddle axis, saddle set, saddle block and saddle ring form saddle
Component, forging and easy to process, save the cost.
(2) saddle assembly and piston are pre-tightened by piston unt in the present invention, instead of being bolted, bolt is avoided to select
The insecurity problem of difficult and nonstandard bolt.
(3) increase saddle and cover part, increased considerably the pre- next deflection of piston unt, so that nut pre-tightens more
Securely and reliably, guarantee that piston rear chamber and front chamber are safe and reliable.
