Description
Technical field
The present invention relates to a kind of marine propeller tuning for Controllable Pitch Propeller, especially a kind ofly can be used for that boats and ships are promoted mainly into, the novel oil cylinder pre-positioning type ship craft propeller hub of thruster, full circle swinging oar.
Background technology
Propeller hub is one of core component of pitch propeller device, and it is the load bearing component of tractive power, is again the final actuating unit of roll adjustment, and therefore, the reliability of propeller hub is most important.Shown in Figure 1, in the existing propeller hub, generally be the right side part that positive car side cylinder is arranged on oil cylinder, i.e. A chamber, the reversing side cylinder is arranged on left part, i.e. the B chamber.This kind structure does not have independently lubricating oil chamber, perhaps reversing B chamber being treated as is the lubricating oil chamber, this not only proposes higher requirement to corresponding part strength in the propeller hub body, and the sealing at blade seat position also improved requirement, increase the risk of hydraulic system leakage greatly, will directly cause increasing the risk of boats and ships operation.
Summary of the invention
The objective of the invention is to: at not having independent lubricating oil chamber in the existing propeller hub, not only higher requirement is proposed corresponding part strength in the propeller hub body, and the sealing at blade seat position also improved requirement, increase the risk of hydraulic system leakage greatly, cause a series of problems such as boats and ships operation risk raising, a kind of later-model oil cylinder pre-positioning type ship craft propeller hub is provided.
The object of the present invention is achieved like this: it mainly comprises propeller hub body, saddle, slide block, blade seat, piston, oil cylinder supporting clapboard, is provided with the oar axle of single oil pipe, and piston is positioned at propeller hub body Inner Front End, and the propeller hub body is connected with the oar axle by bolt; Described propeller hub body and front end oil cylinder integrate, and described piston is installed in propeller hub in-to-in saddle end by screw, and piston nose and propeller hub body inwall, oar shaft end form front chamber; Piston rear end and propeller hub body inwall, supporting clapboard form rear chamber; Oil cylinder supporting clapboard rear end and propeller hub body form the lubricating oil chamber; The disk root of described blade seat is provided with crank pin, and slide block set is on crank pin and be enclosed in the chute at saddle middle part, and slide block and crank pin and chute flexibly connect; Described oil pipe is communicated with rear chamber, and moves with saddle when work.
Oil cylinder supporting clapboard in the described propeller hub body inwall is positioned at the rear end at propeller hub body front end oil cylinder position; Described oil cylinder supporting clapboard is that forging is made, and its endoporus place is provided with the guiding flow ring.
Described propeller hub body front position is provided with oilhole, and oilhole passes through propeller hub body and oar axle.
The invention has the advantages that: increased an oil cylinder supporting clapboard at the oil cylinder position of propeller hub body front end, formed independently lubricating oil chamber, high pressure oil when tuning for Controllable Pitch Propeller is worked like this in the hydraulic efficiency pressure system does not just need to enter propeller hub body rear end, reduced the design strength of propeller hub body, blade seat, therefore can make the size of tuning for Controllable Pitch Propeller littler, more compact structure.The reduction of oil pressure can also reduce the risk of leakage, improves the reliability of hydraulic efficiency pressure system.
Therefore the present invention be advantageous in that: oil cylinder is arranged on front end, and compression area is big, with producing bigger thrust under the equipressure.So just can reduce the working oil pressure of regulating and locking pitch tuning for Controllable Pitch Propeller greatly, the stability of raising system operation.
