Background technology
It is a kind of new hydroelectric generation form that marine tidal-current energy, which generates electricity, using the flowing of tide seawater, promote blade rotate into
And the kinetic energy of generator is translated into, and although marine tidal-current energy generates electricity and very big potentiality is supplied with to future electrical energy, due to tide
Stream can generation technology be still in the initial development stage, it is adaptable to marine tidal-current energy generate electricity speed increasing gear box structure still in the exploratory stage,
Build marine tidal-current energy generate electricity step-up gear during, face many parts rationally it is integrated, to construction and install
All make troubles, therefore, the speedup tooth that people are highly desirable can to provide a kind of compact conformation, safe and reliable marine tidal-current energy generates electricity
The integrated component of roller box assembling.
Utility model content
The purpose of this utility model is：For at present build marine tidal-current energy generate electricity step-up gear during, face
Face many parts rationally not integrated, there is provided a kind of marine tidal-current energy speedup to the particular problem constructed and installation all makes troubles
The main shaft of gear-box is integrated.
What the purpose of this utility model was realized in：A kind of main shaft of marine tidal-current energy step-up gear is integrated, including main shaft,
Planet carrier, biserial conical bearing, cylinder roller bearing, it is characterised in that：Spindle side is using the biserial circle configured face-to-face
Taper roller bearing, double-row conical bearing inner ring is fixed axially through round nut, and the main shaft other end joins with planet carrier interference
Connect, planet carrier side is provided with NU type cylinder roller bearings, NU type cylinder roller bearing inner rings are axially fixed in by pressing plate and bolt
On planet carrier.
In the utility model, side is equipped with spacing before and after the double-row conical bearing inner ring of the spindle side
Ring, side pushes against the shaft shoulder by distance collar, and opposite side distance collar is fastened by round nut and positioned, buckle of the round nut equipped with locking
And bolt；The side of the NU type cylinder roller bearings of the planet carrier side is provided with distance collar, and opposite side is tight against pressing plate.
In the utility model, the high-pressure oil duct that dismounting planet carrier is provided with the main shaft of planet carrier is installed in interference.
In the utility model, the main shaft of marine tidal-current energy step-up gear is integrated by double-row conic bearing outer ring and NU types
