Abstract
A feathering propeller hub structure applied to ship propulsion mainly comprises a propeller hub body, a guide frame, a blade base, a blade, a propeller shaft, an outer oil pipe, an inner oil pipe and a slide block, wherein the guide frame is positioned in the propeller hub body and divides the propeller hub body into a right oil chamber and a left oil chamber. Hydraulic oil is filled in the two oil chambers through the outer oil pipe and the inner oil pipe. A groove is formed under the blade base. The slide block is arranged in the groove. Eccentric pins are arranged on the guide frame. A slider crank mechanism is formed by the guide frame, the eccentric pins, the slide block and the blade base. The blade is in the aheading position when the directions of the eccentric pins are perpendicular to a propeller axis, and the blade driven by the eccentric pins can rotate to a position where the surface of the blade is parallel to the propeller axis nearly. The feathering propeller hub structure has the advantages of being compact in structure, reliable in strength, high in safety and the like. In addition, the feathering propeller hub structure can be applicable to multiple different operating conditions, the resistance of an out-of-service propeller can be greatly reduced, and the total propulsion efficiency is improved, and therefore the purposes of energy saving, consumption reduction and efficient ship propulsion are achieved.
Description
Technical field
The utility model relates to a kind of feathering propeller hub structure that is applied to propulsion of ship, be particularly useful for frequent coming and going, tune limited space and with a plurality of angle of rake boats and ships, such as double end ferry boat, two oar oil tanker, boat and passenger boat.
Background technology
More existing large ships and special purpose boats and ships, the a plurality of propellers of general employing, and these screw propellers all are conventional adjustable propeller usually, when the part screw propeller is out-of-run, if can reduce the resistance of this part screw propeller, just can improve the efficient of total propelling.And conventional adjustable propeller is not worked, and when namely blade pitch was zero, this moment, blade was vertical with axis, the resistance that screw propeller is subject to is maximum, if the position of blade can be transferred to parallelly with axis, at this moment resistance will reduce greatly, but existing conventional propeller hub structure can't satisfy above-mentioned need of work.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provide a kind of compact conformation, intensity is reliable, safe, go for multiple different operating mode, greatly reduce the not resistance of working screw oar, improve total efficient that advances, can be energy-saving and cost-reducing, the feathering propeller hub structure that is applied to propulsion of ship of efficient propelling ship.
The purpose of this utility model is finished by following technical solution, it mainly comprises the propeller hub body, saddle, the blade seat, blade, the oar axle, outer oil pipe, inner oil tube and slide block, described saddle be positioned at the propeller hub body and the propeller hub body is divided into about two oil pockets, these two oil pockets pass into hydraulic oil by outer oil pipe and inner oil tube respectively, described blade seat below has groove, slide block places groove, be provided with eccentric pin on the saddle, described saddle, eccentric pin, slide block and blade seat have formed slider-crank mechanism, and described eccentric pin direction of living in is the positive truck position of blade when vertical with propeller axis, and the blade that drives by eccentric pin can turn to almost parallel position of blade face and propeller axis.
Described blade is bolted on the blade seat by blade, and blade drives by the built-in Fu of propeller hub body and rotates, and oar axle and blind flange are fixed on the propeller hub body together by bolt with flange.
The four sides of described saddle is provided with eccentric pin, and described inner oil tube is communicated with the left oil pocket of propeller hub body, and outer oil pipe is communicated with the right oil pocket of propeller hub body.
Owing to the adjustable propeller that the stroke of feathering is relatively conventional is much bigger, general structure is easy to occur locking phenomenon; And the utility model is arranged on saddle with eccentric pin but not on the blade seat, the larger oil pressure thrust arm of force is arranged like this, can not reduce to produce locking phenomenon owing to the arm of force, makes total more reliable.Blind flange, oar axle couple together by same bolt, have reduced the length of propeller hub, and structure is more compact.
The utlity model has compact conformation, intensity is reliable, the characteristics such as safety height, and it goes for multiple different operating mode, greatly reduces the not resistance of working screw oar, improves total efficient that advances, thereby reaches energy-saving and cost-reducing, the purpose of efficient propelling ship.
