Abstract
The utility model discloses a device for entering of a single bearing stern shaft into a stern shaft tube. The device comprises a flange device; a nylon ring gasket is tightly embedded at the inner annular wall of the flange device; the inner diameter of the nylon ring gasket is slighter greater than the maximal diameter of the stern shaft. The mounting position of a sealing device in front of the stern shaft tube and the special characteristics of the nylon material are ingeniously used, in the whole process that the stern shaft enters the stern shaft tube, the stern shaft is always subjected to the limiting and guiding actions, the friction coefficient between the nylon and the metal is small, and no harm is generated to the stern shaft. After the device is adopted, the stern shaft can easily enter the stern shaft tube, and the mounting efficiency is at least improved by one time; the accident that when the stern shaft is mounted, the shaft collides with a copper pipe and a temperature sensor which are inside the stern shaft tube is effectively avoided, and the safety and the reliability of entering of the stern shaft into the stern shaft tube are greatly improved.
Description
Technical field
The utility model relates to a kind of device that enters stern tube in ship building field for single-bearing stern shaft.
Background technology
Conventional main force ship type, as: bulge carrier, oil carrier, box ship etc., in design and construction before, have 2-3 bearing in stern tube.Along with the continuous progress of technology, there is quite a few main force's ship type to adopt single-bearing form, in stern tube, only have a bearing, there is no front bearing.Stern tube shaft will pass stern tube from cabin, because there is no the spacing of front bearing, when stern tube shaft enters stern tube, be easy to break parts and the stern bearings such as temperature sensor cable, oil pipe and air pipe in stern tube.
Utility model content
The purpose of this utility model is to provide a kind of device that enters stern tube for single-bearing stern shaft.
The purpose of this utility model is achieved by the following technical programs:
A kind of device that enters stern tube for single-bearing stern shaft of the present utility model, it comprises a flange apparatus, the tight setting-in one nylon lining ring of internal ring wall of described flange apparatus, the internal diameter of described nylon lining ring is slightly larger than the maximum gauge of stern tube shaft.Nylon lining ring is embedded in flange, nylon lining ring is little with stern tube shaft friction herein, and stern tube shaft can not wear and tear to axle generation during with nylon friction, and stern tube shaft is when move axially, and described nylon lining ring can not followed movement.When stern tube shaft enters stern tube, this device is fixed on to sealing arrangement installed position before stern tube, stern tube shaft is played to spacing and directional tagging.
For the ease of installation, dismounting and stern tube shaft, enter, described flange apparatus cuts along body lines centering, form divide equally two equal portions.
According to the bolt hole on sealing arrangement seam position before stern tube, join brill, the aperture of the bolt hole on described flange apparatus and distribution thereof are identical with the bolt hole pore size and distribution on sealing arrangement seam position before stern tube.
Shearing force to device bolt of rear end plate while entering stern tube for reducing stern tube shaft, this device is designed to step at its axis direction, towards stern tube one side stepped diameters than stern tube before the external diameter of sealing arrangement seam position smaller, during installation, step is towards stern tube one side installation.
The utility model compared with prior art has the following advantages:
1, the utility model uses the installation site of the front sealing arrangement of stern tube dexterously, and the property of nylon material, at whole stern tube shaft, enter in the process of stern tube, all the time stern tube shaft is played to spacing and directional tagging, and nylon and metal friction coefficient are little, can not cause damage to stern tube shaft.
2, adopt after device of the present utility model, can easily stern tube shaft be entered in stern tube, installation effectiveness at least doubles (orthodox method needs 6 work that people could complete, use this device then only need 3 people's cooperations just can complete).
3, compare traditional installation method by instruments such as cucurbits, the accident that copper pipe and temperature sensor are collided inside axle and stern tube occurs in the time of can effectively avoiding stern tube shaft is installed.The utility model device improves the safety and reliability that stern tube shaft enters stern tube greatly.
Accompanying drawing explanation
Fig. 1 of the present utility modelly enters stern tube device schematic diagram for single-bearing stern shaft;
Fig. 2 is the section-drawing of Fig. 1;
Fig. 3 is the erection plan of the utility model device;
Fig. 4 is that stern tube shaft enters stern tube schematic diagram.
The specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is further described:
As shown in Fig. 1～4, be one of embodiment of a kind of device that enters stern tube for single-bearing stern shaft of the present utility model, it comprises a flange apparatus 1, the tight setting-in one nylon lining ring 2 of internal ring wall of described flange apparatus 1, the internal diameter of described nylon lining ring 2 is slightly larger than the maximum gauge of stern tube shaft; Described flange apparatus 1 cuts along body lines centering, form divide equally two equal portions; The aperture of the bolt hole 3 on described flange apparatus 1 and distribution thereof are identical with the bolt hole pore size and distribution on sealing arrangement seam position before stern tube; This device is designed to step 4 at its axis direction, towards stern tube one side stepped diameters than stern tube before the external diameter of seam position of sealing arrangement 5 smaller, during installation, step is installed towards stern tube one side.
The above embodiment has only expressed preferred implementation of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
