Abstract
The utility model relates to a protecting apparatus for a stern-shaft sealing system for a middle-small size ship. The common protecting apparatus for the stern-shaft sealing system is a protecting cover which is arranged on the outer side of the sealing system correspondingly. Because a gap exists between the protective cover and a propeller, the stern-shaft sealing system is easy to destroy when the propeller encounters objects such as fish nets, steel cables, etc. The protecting apparatus for a stern-shaft sealing system of the utility model is composed of two transitional protecting rings, a net clearing ring and an oil seal culvert body. The configuration makes the winding objects not easy to wind tightly and makes the winding objects pass forwards across the sealing system. The net cleaning rings and the oil seal culvert body form a cutting shape, which prevents the winding objects across the sealing system from entering the sealing system to perform the function of protecting the stern-shaft sealing system.
Description
The utility model is the protective equipment of a kind of medium and small-scale vessel stern shaft seal system.
The protective equipment (Fig. 1) of common medium and small-scale vessel stern shaft seal system is to be equipped with a guard shield to dress in the outside of sealing system.This structure is because guard shield welds dress, and precision is relatively poor, between guard shield and propeller hub certain clearance is arranged.Boats and ships under sail, thinner fishnet can enter in the protective equipment by the gap between guard shield and the propeller hub, and is wrapped on the anti-wearing liner, owing to constantly pile up, easily sand prevention glue ring and rubber oil sea is destroyed, and causes leakage of oil to leak.In addition, when boats and ships navigated by water in the shallow water territory, some sank to water-bed waste steel wire rope and also can be wrapped between guard shield and the propeller hub, be easy to guard shield is taken off, cut off the exerted bolt of sealing system, cause leakage of oil to leak, force the boats and ships repairing of suspending, cause bigger economic loss.
The purpose of this utility model is to design a kind of protective equipment that is applicable to the stern shaft seal system that medium and small-scale vessel uses, and reduces because sealing system is damaged the Ship's Repair that is caused.
The utility model by the transition guard ring, remove net circle and oil sealing and contain body etc. and partly form.Because the rear end of two transition guard rings respectively has two symmetrical grooves opening on a torsion boss and the propeller cavitation to inlay, and be close to propeller cavitation, the front end of transition guard ring be enclosed within oil sealing and contain the net circle that removes of external side and closely be connected, so the profile of structure makes that not only twining object is difficult for twining extremely, and the winding object can not directly be entered in the protective equipment, but cross sealing system forward along construction profile between propeller cavitation and transition guard ring.Because structural strength is bigger, it is destroyed to have guaranteed that device proper is difficult for.When ship's navigation, remove the net circle and propeller cavitation rotates together and contain body with changeless oil sealing forms shearing.Stop entering of the winding object of crossing sealing system, thereby protected the stern shaft seal system effectively, avoided unnecessary economic loss.
Concrete structure of the present utility model is provided by following examples and accompanying drawing.
Fig. 1 is common medium and small-scale vessel stern shaft seal systematic protection apparatus structure schematic representation.
Fig. 2 is a medium and small-scale vessel stern shaft seal systematic protection apparatus structure schematic representation of the present utility model.
Fig. 3 is the A-A sectional drawing of Fig. 2.
With reference to Fig. 1, Fig. 2, sand prevention glue ring gland (7) on the front end sleeve that has the anti-wearing liner of locating slot (3), sand prevention glue ring (5) is embedded the interior rear flank of sand prevention glue ring gland (7) successively oil sealing pressing plate (8), rubber oil sea (10) are enclosed within on the anti-wearing liner (3), O type O-ring seal (9) embeds in the groove of oil sealing pressing plate (8).The outside has several oil sealings of shearing dividing plate (28) culvert bodies (11) to be enclosed within on the rubber oil sea (10), adjusting washer (disk) (12) is inserted oil sealing contain in the body (11).Adorn appropriate stern shaft seal system and be enclosed within on the stern tube shaft (2) above, and be close to bearing (14), use bolt (13) that oil sealing is contained body (11) then and be connected fasteningly with bearing (14), stern tube shaft pipe (15), with bolt (6) sand prevention glue ring gland (7), oil sealing pressing plate (8) are fastened on oil sealing and contain on the body (11).
Guard shield (16) is enclosed within on beauty's frame (18), fastening with screw (17).
To have several nets that remove that remove net window (27) and the husky hole of row (26) and enclose (21), empty boasting is contained on the body (11) at oil sealing.
The propeller cavitation (1) that will be embedded with O-ring seal (24) and have a symmetrical grooves be enclosed within adorn on the stern tube shaft (2) appropriate.
Be fastened on the propeller cavitation (1) with the rear end of bolt (4) anti-wearing liner (3).
Transition guard ring (19), (22) assembly that will respectively have a torsion boss (25) are having on the propeller cavitation of symmetrical grooves (1), and its inboard is enclosed in the locating slot of anti-wearing liner (3), with bolt (23) two transition guard rings (19), (22) are tightened up.
The net of empty boasting being contained on the body (11) at oil sealing with bolt (20) that removes encloses (21), is fastened on transition guard ring (19), (22).
By above-mentioned protective equipment, can protect medium and small-scale vessel stern shaft seal system, thereby reduce Ship's Repair, increase economic efficiency.
Claims (3)
1, a kind of be applicable to that medium and small-scale vessel uses by excessive guard ring (19), (22), remove the stern shaft seal systematic protection device that net circle (21) and oil sealing culvert body (11) four parts are formed, it is characterized in that transition guard ring (19), (22) are fastened on the propeller cavitation (1), the net circle (21) that removes that empty boasting is contained on the body (11) at oil sealing is fastened on transition sheath (19), (22), and the outside has the oil sealing culvert body (11) of some shearing dividing plates (28) to be fastened on the stern tube shaft pipe (15).
2,, it is characterized in that a torsion boss (25) is respectively arranged on two transition guard rings (19), (22) according to the stern shaft seal systematic protection device of claim 1.
3,, it is characterized in that except that there being several to remove net window (27) and row husky hole (26) on the net circle (21) according to the stern shaft seal systematic protection device of claim 1.
