The utility model content
The purpose of the utility model is: to 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 purpose of the utility model is achieved in that 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 through bolt; Described propeller hub body and front end oil cylinder integrate, and said piston is installed in propeller hub in-to-in saddle end through 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 said 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; Said oil pipe is communicated with rear chamber, and when work, moves with saddle.
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; Said oil cylinder supporting clapboard is that forging is processed, and its endoporus place is provided with the guiding flow ring.
Said propeller hub body front position is provided with oilhole, and oilhole passes through propeller hub body and oar axle.
The advantage of the utility model is: increased an oil cylinder supporting clapboard at the oil cylinder position of propeller hub body front end; Be able to form independently lubricating oil chamber; High pressure oil when tuning for Controllable Pitch Propeller is worked like this in the hydraulic efficiency pressure system just need not get into 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 being also advantageous in that of the utility model: 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.
