Abstract
The utility model provides a marine tailing axle screw and cap double -purpose clog, it is including the locking bolt, the double -purpose clog, locking and cap, and cap stopping double -screw bolt, wherein, locking and cap sleeve dress are in stern axle head portion, locking and cap cross -section are the U -shaped, its U -shaped opening part is equipped with the solid fixed ring of outside extension, and cap stopping double -screw bolt follow U -shaped bottom penetrates its locking epaxially at the stern, the screw is installed at the stern epaxially, gu fixed ring hugs closely the inboard on the screw terminal surface, be equipped with on the anchor ring in the double -purpose clog and solid fixed ring shape matched with echelonment locking step, this echelonment locking step suit is in the solid fixed ring outside, the locking bolt passes the double -purpose clog and locks it on the screw. This scheme easy maintenance, locking is guaranteed, and whole space is little, and the appearance is pleasing to the eye.
Description
Technical field
This utility model relates to technical field of ships, refers in particular to stern arrangement and propeller peculiar to vessel cap double-purpose retainer.
Background technology
Propeller stop cap locking Principle Method are a lot, locking cap have the tapered dovetail groove of plane, make a taper dovetail groove, cone pin other end car becomes cylinder, screw propeller cap when assembling to be inserted into by taper pin and cap dovetail groove, in the hole therein, six holes bored of alignment propeller end face, then it is tightened on tack bottle opener stud and cap is joined on two M holes of brill.There are two kinds of screw threads about two and cap car and different two lockings of pitch cap.It is tightened onto propeller end face simultaneously.Also have a kind of with the most use, propeller end face bores 6 hole tapping, stern tube shaft cap dig two square end faces and propeller six hole concentric, bore holes, assembling time and cap screw after and cap on holes must be directed on 2 holes in propeller six hole, two the tightest two studs of screw hole, so there is the problem being unable to explain clearly, propeller conicity locking to be prepared is difficult again aligns two holes in six holes, so propeller has the problem loosening propeller, the propeller installed also has a lot of difficulty hammer to beat when dismounting, burning torch burns, and is difficult to problems such as loosening.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of stern arrangement and propeller peculiar to vessel easy to maintenance, overall space is little, good looking appearance and cap double-purpose retainer.
For achieving the above object, technical scheme provided by the utility model is: stern arrangement and propeller peculiar to vessel cap double-purpose retainer, it includes clamping screw, double-purpose retainer, locking cap, wherein, locking cap sleeve are contained in stern tube shaft end, double-purpose retainer is sleeved on locking cap, it is drilled with same section on the end face circumference of double-purpose retainer and propeller and divides Zhou Yuankong, circular hole internal tapping on propeller, locking cap are screwed and are close on the end face of propeller by clamping screw, locking cap outer peripheral face turning form flange shape end face, double-purpose retainer inwall is provided with the concavity step trough matched with this flange shape end face, the concavity step trough of retainer is less than also cap flange shape end surface thickness.
Described locking cap outer end are tightened on the internal thread of stern tube shaft end by also cap retaining stud.
This programme double-purpose retainer assembling time not by any control, any direction locking can be screwed at propeller cap, and cap to loosen and four screws need to be elongated or break, propeller to loosen, only need to screw four bolts on retainer again and revolve propeller loosening several years silk after propeller cap case less and just can loosen and dismantle propeller, can effectively save installation time, and to propeller stop with to pull effect fine, convenient to maintenance, stop is more guaranteed, overall space is little, good looking appearance.
