Description
Technical field
The utility model relates to a kind of supporting, particularly a kind of boring bar rolling bearing be applied in marine shafting bore hole stern pipe.
Background technology
Bore hole is the further processing to the hole forging, cast out or get out, and bore hole can expand aperture, improves precision, reduces surface roughness, can also correct the deflection of original axially bored line preferably.Former and later two bearings of screw shaft of ship need to carry out Boring, to reach the axiality requirement of two bearings.For spitkit, the stern tube shaft diameter of axle is less, but the spacing of two bearings is far away, distance can reach about 5000mm, this just makes boring bar thin and grows, and causing boring bar pars intermedia branch to produce trickle bending, being just difficult to reach machining accuracy when bore hole if do not increased intermediate supports to boring bar.And between two bearings, be also provided with stern pipe, in stern tube shaft stern pipe, intermediate support is set to boring bar very difficult, this Boring machine factory is at a complete loss as to what to do.Therefore, the supporting of a kind of applicable spitkit tube shaft bearing Boring of development, big L/D ratio boring bar is badly in need of in our enterprise.
Utility model content
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art, provides that a kind of structure is simple, cost is low, easy for installation and contribute to improving the boring bar rolling bearing be applied in marine shafting bore hole stern pipe of bore hole success rate and working (machining) efficiency.
The technical scheme that the utility model adopts is: the utility model comprises supporting body, be arranged at least one rolling bearing in described supporting body and several clamping screws suitable with described supporting body, during use, the described boring bar rolling bearing be applied in marine shafting bore hole stern pipe is enclosed within the precalculated position on boring bar, described boring bar penetrates from one end of described stern pipe, pass from the other end, the described boring bar rolling bearing be applied in marine shafting bore hole stern pipe loads described stern pipe with described boring bar, clamping screw described in several radially penetrates from described stern pipe outside, and evenly secure the above supporting body.
The described boring bar rolling bearing be applied in marine shafting bore hole stern pipe also comprises and the nut that be weldingly fixed on described stern pipe outside suitable with described clamping screw.
Two described rolling bearings coaxially arranged with described stern pipe are had in described supporting body.
Spacer ring is provided with between two described rolling bearings.
One end of described supporting body is provided with spacing preiection, and the other end is provided with circlip, and described rolling bearing is between described spacing preiection and described circlip.
Described supporting body arranged outside is fluted, and the contact point of described clamping screw and described supporting body is positioned at described groove.
The width of described groove is 2-5 times of the major diameter of thread of described clamping screw.
The beneficial effects of the utility model are: because the utility model comprises supporting body, be arranged at least one rolling bearing in described supporting body and several clamping screws suitable with described supporting body, during use, the described boring bar rolling bearing be applied in marine shafting bore hole stern pipe is enclosed within the precalculated position on boring bar, described boring bar penetrates from one end of described stern pipe, pass from the other end, the described boring bar rolling bearing be applied in marine shafting bore hole stern pipe loads described stern pipe with described boring bar, clamping screw described in several radially penetrates from described stern pipe outside, and evenly secure the above supporting body, so, the utility model structure is simple, cost is low, solve the problem that spitkit tube shaft bearing Boring cannot arrange intermediate support, the success rate of bore hole is made to bring up to more than 90% by original about 50%, Boring efficiency also improves three or four times.
In addition, the width due to described groove is 2-5 times of the major diameter of thread of described clamping screw, so can greatly reduce installation difficulty of the present utility model, the utility model can easily be arranged in stern tube shaft tail pipe, effectively improve operating efficiency.

Detailed description of the invention
As shown in Figure 1 to Figure 3, in the present embodiment, the utility model comprises supporting body 2, be arranged on two rolling bearings 3 in described supporting body 2 and several clamping screws 4 suitable with described supporting body 2, in the present embodiment, be provided with spacer ring 7 between two described rolling bearings 3, two described rolling bearings 3 are coaxially arranged with described stern pipe 1.
In the present embodiment, the boring bar rolling bearing be applied in marine shafting bore hole stern pipe described in also comprises and the nut 6 that be weldingly fixed on described stern pipe 1 outside, described clamping screw 4 and described nut 6 threaded engagement suitable with described clamping screw 4.
In the present embodiment, one end of described supporting body 2 is provided with spacing preiection 8, and the other end is provided with circlip 9, and described rolling bearing 3 is between described spacing preiection 8 and described circlip 9.
In the present embodiment, described supporting body 2 arranged outside fluted 10, described clamping screw 4 is positioned at described groove 10 with the contact point of described supporting body 2.
In the present embodiment, the width of described groove 10 is 3.5 times of the major diameter of thread of described clamping screw 4.
During use, first on described stern pipe 1, open three holes around its axle, then described nut 6 in coaxial welding on hole, described clamping screw 4 and described nut 6 threaded engagement, the described boring bar rolling bearing be applied in marine shafting bore hole stern pipe is enclosed within the precalculated position on boring bar 5, described boring bar 5 penetrates from one end of described stern pipe 1, pass from the other end, the described boring bar rolling bearing be applied in marine shafting bore hole stern pipe loads described stern pipe 1 with described boring bar 5, width due to described groove 10 is 3.5 times of the major diameter of thread of described clamping screw 4, so then greatly can reduce the difficulty that it is aimed at, i.e. installation difficulty, described clamping screw 4 radially penetrates from described stern pipe 1 outside, and evenly secure the above supporting body 2.Described rolling bearing 3 can be regulated by described clamping screw 4 with the axiality of former and later two bearings of screw shaft of ship.
