Description
Technical field
The utility model relates to a kind of boats and ships tuning for Controllable Pitch Propeller, is a kind of tuning for Controllable Pitch Propeller with streamlined reefer housing specifically.
Background technology
Present most tuning for Controllable Pitch Propeller changes pitch and carries out by the displacement oil cylinder.As shown in Figure 1, a lot of roll adjustment displacement oil cylinders 1 all is arranged on the back of propeller hub 3, by 4 motions of the piston in the displacement oil cylinder 1, reaches the purpose that changes blade pitch.Because propeller hub 3 and displacement oil cylinder 1 long period of soaking are very serious by marine corrosion in seawater, so propeller hub 3 and displacement oil cylinder 1 all will adopt the material of anti-marine corrosion, commonly nickel aluminium bronze or corrosion-resistant steel, by cast form, fine limit work then.But adopt nickel aluminium bronze or corrosion-resistant steel as cast material, occur foundry defects such as pore, sand holes easily, quality just is difficult to guarantee, has a strong impact on the build guality of part.Adding displacement oil cylinder 1 is to bear high-voltage part, very sensitive to the defective of foundry goods, and the situation of scrapping owing to the defective of foundry goods is often arranged, and has so just increased use cost and maintenance cost.
Summary of the invention
The purpose of this utility model is to overcome that tuning for Controllable Pitch Propeller displacement oil cylinder corrodes easily in the prior art, and strict and high defective and the deficiency of manufacturing cost to material requirements provides a kind of with the tuning for Controllable Pitch Propeller of being with streamlined reefer housing.It can effectively prevent the corrosion of displacement oil cylinder, and selection range is wide, low cost of manufacture.
For achieving the above object, technical solution of the present utility model is: the tuning for Controllable Pitch Propeller of band streamlined reefer housing, comprise the displacement oil cylinder that is arranged on the propeller hub end, and the outside seal of described displacement oil cylinder is covered with streamlined reefer housing, and the open end of streamlined reefer housing is through being bolted on the propeller hub.
Described streamlined reefer housing adopts nickel aluminium bronze or stainless steel sheet or engineering plastics to make.
Be provided with seal ring between described streamlined reefer housing and the propeller hub.
Described seal ring is the O RunddichtringO.
Described displacement oil cylinder adopts alloy steel forging or forged steel pieces to make.
Compared with prior art, the beneficial effects of the utility model are:
1. adopt streamlined reefer housing that displacement oil cylinder cover is got up, effectively isolated seawater, make seawater can not corrode the displacement oil cylinder again, prolonged the service life of displacement oil cylinder and tuning for Controllable Pitch Propeller greatly.
2. streamlined reefer housing adopts resistant to corrosion nickel aluminium bronze or stainless steel sheet or engineering plastics to make, and anticorrosion ability is good, and cost is extremely low; Between streamlined reefer housing and propeller hub, be provided with seal ring, further improved sealing effectiveness.
3. the utility model is simple in structure; easy for installation; owing to the displacement oil cylinder has been taked the streamlined reefer housing seal protection measure of anti-marine corrosion; make the displacement oil cylinder can adopt better alloy steel forging of mechanical characteristics or forged steel pieces material; can avoid Casting Parts foundry defects such as pore, sand holes to occur, the diameter of displacement oil cylinder can design forr a short time, and manufacturing cost greatly reduces; simultaneously, be convenient to improve the accuracy of manufacture of displacement oil cylinder.
Description of drawings
Fig. 1 is the structural representation of existing tuning for Controllable Pitch Propeller;
Fig. 2 is a structural representation of the present utility model.
Among the figure: displacement oil cylinder 1, streamlined reefer housing 2, propeller hub 3, piston 4, seal ring 5, bolt 6.
The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment the utility model is described in further detail:
Referring to Fig. 2, the tuning for Controllable Pitch Propeller of band streamlined reefer housing of the present utility model comprises the displacement oil cylinder 1 that is arranged on propeller hub 3 ends, and the outside seal of described displacement oil cylinder 1 is covered with streamlined reefer housing 2, and the open end of streamlined reefer housing 2 is fixed on the propeller hub 3 through bolt 6.
Among Fig. 2, the open end of streamlined reefer housing 2 is fixed on the end face of propeller hub 3 through bolt 6, but streamlined reefer housing 2 also can cover on the outer round surface of propeller hub 3 ends, and fixes from the outer wall radial seal of propeller hub 3 with bolt 6, also can play sealing and corrosion-resisting function to displacement oil cylinder 1.
It is barrel-shaped that described streamlined reefer housing 2 is made the circular cone that opening is big, the bottom is little by displacement oil cylinder 1 exterior shape, and its open end is that bung covers on displacement oil cylinder 1 exterior propeller hub 3.Because 2 of streamlined reefer housings play sealing and corrosion-resisting function, need not to bear the pressure of pressure oil, so the requirement of mechanical strength of streamlined reefer housing 2 is lower, so streamlined reefer housing 2 can adopt nickel aluminium bronze or stainless steel sheet or engineering plastics to make, with the reduction manufacturing cost.
For improving the sealing effectiveness of streamlined reefer housing 2, can between described streamlined reefer housing 2 and propeller hub 3, be provided with seal ring 5.Described seal ring is preferably the O RunddichtringO.
Because the corrosion prevention to displacement oil cylinder 1 material requires to reduce, so described displacement oil cylinder 1 can adopt alloy steel forging or forged steel pieces to make, the mechanical characteristics of forged steel pieces is higher than nickel aluminium bronze far away, therefore can bear higher pressure, the diameter of displacement oil cylinder 1 and propeller hub 3 can design forr a short time so, the required flow of hydraulic efficiency pressure system can be littler, and the components and parts cost is lower.
Described streamlined reefer housing 2 is installed in the outside of displacement oil cylinder 1, and displacement oil cylinder 1 has been covered, and with the sealing of " O " RunddichtringO, with stainless bolt 6 streamlined reefer housing 2 is fixed on the outside of propeller hub 3 again between streamlined reefer housing 2 and propeller hub 3.Streamlined reefer housing 2 adopts nickel aluminium bronze foundry goods or stainless steel sheet to be welded, and makes simplyr, has saved cost.
Simultaneously, because the corrosion prevention of displacement oil cylinder 1 material requires to reduce, just can adopt alloy steel forging or forged steel pieces to make, displacement oil cylinder 1 endoporus and cylindrical all can be designed to cylindric, and fine limit work is convenient to improve the precision of its manufacturing again.Because alloy steel forging has better mechanical characteristics than the nickel aluminium bronze foundry goods that adopts in the past, can avoid casting to produce foundry defects such as pore, sand holes, and manufacturing cost significantly reduces, with alloy steel 40Cr forging is example: the manufacturing cost of nickel aluminium bronze foundry goods is approximately 160 yuan/kg, and 30 yuan/kg of 40Cr forging cost less than.After adopting alloy steel forging or forged steel pieces, abrasion strength resistance when displacement oil cylinder 1 cooperates with piston 4 is higher, the wear resisting property of displacement oil cylinder 1 and service life improve, and can bear higher pressure, the diameter of displacement oil cylinder 1 and piston 4 can also design forr a short time, the required flow of hydraulic efficiency pressure system also can be littler, and the required cost of corresponding components and parts also greatly reduces.
Referring to Fig. 2, described seal ring 5 is " O " type, be placed between streamlined reefer housing 2 and the propeller hub 3, during installation, after putting seal ring 5 earlier, cover again, be locked with bolt 6 at last when streamlined reefer housing 2, so just can prevent that seawater from infiltrating from the binding site between streamlined reefer housing 2 and the propeller hub 3, improved sealing effectiveness by actv..
