Abstract

The utility model discloses a propeller for the marine sailing and propelling, which is composed of an inner core which is a steel skeleton, and multi-layer glass fiber cloth which is superposed up and down and is pasted with adhesives. The utility model is formed by being desquamated through a mold; The steel skeleton glass steel propeller, which is distinguished from the traditional propeller in material and structural, has the advantages of a light self weight, a high speed, high strength, good physical and mechanical properties, high elasticity, unease of fracture of blades, small mechanical wear, low oil consumption, etc.

Description

Steel structure reinforced fibreglass of the propeller

What the utility model was related is the boats and ships accessories, is a kind of propeller for the ship running propelling.

As everyone knows, the formalness of propeller all is through tight Mechanics Calculation and the optimal morphology of precise design, thereby formalness that we can say various screw slurries is consistent substantially, so for the in-use performance that improves propeller, can't explore from the aspects such as formalness structure that change it again, and must carry out in-depth study from changing aspects such as its material and inner structure.Propeller present and the boats and ships coupling roughly can reduce four kinds of materials, as four kinds of cast steel, cast copper, cast iron and nylon, shortcomings such as first three propeller of planting material exists that own wt is big, the machine abrasion loss is big when easy fracture, oil consumption height, boats and ships reverse gear, though the propeller of nylon material can overcome these shortcomings, but it is the low material of a kind of softening point, also be the abrasion resistant material just easy deformation of situation that meets the temperature difference not, the effective efficiency when then out of reach advances is so also be inconsiderable.

The utility model is exactly the variety of issue that exists at said propeller, and the improvement of carrying out material and inner structure has proposed a kind of steel frame glass-felt plastic propeller, this screw slurry can reach the own wt that alleviates propeller, improves the purpose of its structural strength.

Accompanying drawing is a structural representation of the present utility model.

Among the figure: 1 is that slurry axle, 2 is that axis hole, 3 is that keyway, 4 is that blade, 5 is that steel pipe, 6 is steel plate.

6 is steel plate.

Now narrate technical characterictic of the present utility model in conjunction with the accompanying drawings.

Inside of the present utility model is included in a steel frame of being made up of steel pipe 5 and three block plates 6, three block plates 6 of this steel frame are to weld respectively according to all trisections in the garden of steel pipe 5, its inner core as propeller is positioned at the interlayer position of propeller, it is reinforced rib as propeller, it is sightless from the formalness of propeller, in addition, the utility model is superimposed with the glass fabric of multilayer on the aspect up and down of steel frame, its composition is mainly alkali-free glass and middle alkali glass, bond with the adhesive agent that contains epoxy resin and universal Polyester resin between every layer of glass cloth, call in a certain amount of silica flour in the adhesive agent increasing the wearing coefficient of propeller, so constituted the utility model steel frame glass-felt plastic propeller on said structure and the material.

The utility model is implemented by following process, at first that mold cleaning is clean, use cured polishing, treat that cured mould reaches certain bright degree, in each blade mould of mould, coat the resin glue that adds a certain amount of silica flour, repave the upper glass fiber cloth, for several times, treat that its thickness reaches original design thickness one half of blade so repeatedly, to place mould on the aspect of repeatedly overlapping glass cloth by steel pipe 5 and the good steel frame of three block plates, 6 welding, with above-mentioned adhesive phase layer Binder fiber cloth, every layer of glass cloth all intersects in slurry axle 1 presses layer, and inserts the compound of fibrous glass and adhesives at the hole place then, cover through cleaning out and with the counterdie of cured polishing, behind the matched moulds, carry out movable nip drum, make in the mould and enrich, behind the certain hour demoulding, static balance test is done in polishing then, is the finished product propeller.

The utility model own wt light (only be cast iron screw slurry weight 1/4), fltting speed is fast, and the mechanical strength height, good springiness, the tip of blade can in the situation of excess load The rigidity elastic force of reinforcing according to its elasticity and propeller inner layer metal skeleton becomes automatically temporarily; so easy fracture not; when ship-handling needs reverse gear; wear intensity to machinery is little; thereby playing again the effect of protection parts, this propeller is used per hour fast 1-1.5 kilometer of speed per hour through practice, per hour 0.5 kilogram of low consumption of fuel consumption; precipitate and high improve about 10 times, the product of the utility model for the update of boats and ships propeller thought by ship inspection department.

Claims

1, a kind of boats and ships propeller, the steel frame that it is characterized in that being made up of a steel pipe 5 and three block plates 6 is superimposed with the glass fabric of multilayer as inner core on the aspect up and down of steel frame, bond with resinoid bond between the Bo Weibu.
