Description
Technical field
The present invention relates to stern Manifold technology field, more particularly to a kind of stern pipe device for saving installation space.
Background technology
The core of extra large work ship is exactly propulsion capability, and stern pipe is the bearing support assembly of propeller shaft.Shafting is installed in ship
In need bracing wire or beat laser to be accurately positioned, the concentricity of bearing to be controlled in millimeter, to ensure the smooth running of stern tube shaft.
If the centre of location precision of assembling is inadequate, the clamping stagnation of rudder stock operating, galloping, can make the eccentric wear of propeller shaft, cause
Ship vibrations aggravation, while increase the power loss of host.The poor fit of water-stop and propeller shaft can be caused when serious, is made
Oil leak and oil-lubricated bearing high temperature scaling loss are even caused into eccentric wear.
In traditional architectures, as shown in Fig. 2, to reduce the assembly process on ship, rear stern bearing is all first to be fitted in stern pipe
Back segment inner sleeve, preceding stern bearing are all first to be fitted in stern pipe leading portion inner sleeve, and stern pipe is welded direct on hull after first bracing wire, then
The center line of stern pipe back segment inner sleeve and stern pipe leading portion inner sleeve is positioned by finish draw line.Finally by being bolted, and use ring
Oxygen is filled.The structure type, inner sleeve are filled by epoxy, and single end face is connected by bolt with stern pipe, and general shaft diameter is big,
Stern bearing is also grown, and inner sleeve is also grown, be generally attained by 1 meter how long.On the one hand, it is default will to hang in stern pipe for the inner sleeve of the structure
Position, difficulty of construction is big, is particularly being inserted in, it is necessary to which Ship Structure, which reserves very big space, gives stern pipe leading portion for stern pipe leading portion inner sleeve
Inner sleeve could be installed, and be unfavorable for the maintaining in hull structural design and later stage.On the other hand, the structure is heavy at a high speed in shafting
During idling is moved, stern bearing bears very big twisting resistance, so single end face is connected by bolt with stern pipe, can be severe
In the case of may cause inner sleeve epoxy cracking, cause the leakage of stern pipe lubricating oil and the infiltration of seawater, cause marine pollution and
Bearing unlubricated friction scaling loss.
