Description
Technical field
The utility model relates to technical field of ships, refer in particular to marine screw shaft spindle nose power connecting mechanism.
Background technique
Existing stern tube shaft spindle nose is cylinder, is connect directly through after connecting bushing with cabin internally-powered system, this side
It is prone to wear at formula spindle nose, while cylindrical spindle nose is easy front and back and walks, and largely effects on power transmission effect.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, provide it is a kind of it is structurally reasonable, using effect is good
Marine screw shaft spindle nose power connecting mechanism.
To achieve the above object, technical solution provided by the utility model are as follows: marine screw shaft spindle nose power connecting mechanism,
It includes connecting bushing, and connecting bushing is cylindrical, and inner cavity forms the stern tube shaft inserting room of cone, and stern tube shaft inserts ceiling portion
It is provided with keyway；Stern tube shaft inserting smaller one end in room extends to form spindle nose room, and spindle nose indoor location has tube shaft bearing, and spindle nose room end is expanded
Spread is at sealed step, embedded with the sealing ring of annular in sealed step, the connecting bushing end periphery of spindle nose room one end towards
External expansion forms connection ring, and connecting hole is evenly distributed on the anchor ring of connection ring, and stern tube shaft spindle nose passes through stern tube shaft and inserts room, stern tube shaft axis
It holds, connect after sealing ring with cabin internally-powered system；Bearing lubrication is reserved between cavity wall in tube shaft bearing outer peripheral surface and spindle nose room
Room shrinks to form stair-stepping limit section at stern tube shaft spindle nose, limit section pass through after tube shaft bearing, sealing ring with cabin internally-powered system
Connection, limits and is reserved with spindle nose lubricating chamber between the cascaded surface of section and tube shaft bearing, spindle nose lubricating chamber connect with bearing lubrication room.
The connecting bushing is equipped with the oiling connector connecting with bearing lubrication room.
The internal diameter of the spindle nose room is greater than the internal diameter of stern tube shaft inserting room maximum.
The utility model inserts in stern tube shaft after adopting the above scheme and increases lubrication zone between room and spindle nose room, then pass through
Oiling connector injects lubricating oil, and lubrication zone is sealed by sealing ring, and the wear rate of spindle nose can be effectively reduced in this way,
Increase the service life of tube shaft bearing simultaneously, it is good using the structurally reasonable, using effect after this programme.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
Fig. 2 is the connecting bushing inner-cavity structure schematic diagram of the utility model.
Specific embodiment
Below with reference to all attached drawings, the utility model is described in further detail, the preferred embodiment of the utility model are as follows: ginseng
See attached drawing 1 and attached drawing 2, marine screw shaft spindle nose power connecting mechanism described in the present embodiment includes connecting bushing 1, connecting bushing
1 is cylindrical, and inner cavity forms the stern tube shaft inserting room 2 of cone, and stern tube shaft inserting is provided with keyway at the top of room 2；Stern tube shaft insert room 2 compared with
Small one end extends to form spindle nose room 3, and the internal diameter of spindle nose room 3 is greater than the internal diameter of stern tube shaft inserting 2 maximum of room, installation in spindle nose room 3
There is tube shaft bearing 4,3 end extended of spindle nose room forms sealed step 5, the sealing ring of annular, spindle nose room are embedded in sealed step 5
The 1 end outer peripheral surface of connecting bushing of 3 one end extends to the outside to form connection ring 6, and connection is evenly distributed on the anchor ring of connection ring 6
Hole, stern tube shaft spindle nose are connect after passing through stern tube shaft inserting room 2, tube shaft bearing 4, sealing ring with cabin internally-powered system；4 periphery of tube shaft bearing
It is reserved with bearing lubrication room 7 between 3 internal chamber wall of face and spindle nose room, shrinks to form stair-stepping limit section at stern tube shaft spindle nose, is limited
Section is connect after passing through tube shaft bearing 4, sealing ring with cabin internally-powered system, is limited and is reserved between the cascaded surface of section and tube shaft bearing 4
There is spindle nose lubricating chamber 9, spindle nose lubricating chamber 9 connect with bearing lubrication room 7, and connecting bushing 1 is equipped with and connect with bearing lubrication room 7
Oiling connector 8.The present embodiment is inserted in stern tube shaft increases lubrication zone between room and spindle nose room, then passes through oiling connector injection lubrication
Oil, lubrication zone are sealed by sealing ring, the wear rate of spindle nose can be effectively reduced in this way, while increasing tube shaft bearing
Service life, it is good using the structurally reasonable, using effect after the present embodiment.
The embodiment of the above is only the preferred embodiment of the utility model, and the reality of the utility model is not limited with this
It applies range, therefore all shapes according to the utility model, changes made by principle, should all cover in the protection scope of the utility model
It is interior.
