Abstract

The securing device (1) for transmitting thurst between an engine, especially a diesel engine, and the hull (15) of a ship comprises a thrust sleeve (16) running through an aperture (150) in the hull (15) of the ship which has a larger cross-section than that of the thrust sleeve (16). The space (1516) between the edge of said aperture (150) in the hull (15) of the ship and the outside of the thrust sleeve (16) is filled to excess in the region of the aperture (150) with a casting compound (19). A bolt (14) running through the thrust sleeve (16) and is supported on one side on the engine casing (11, 13) and on the other side on the hull (15) of the ship is pretensioned.

Description

Transmit the device of thrust

The present invention relates to a kind of by independent claims 1 propulsion force transmission device as described in the preamble.The transmission shaft of the propeller of ship or the propeller of ship is not when being bearing on the hull by thrust baring, and thrust is just by driving engine, or rather, is delivered on the ship by the casing of driving engine.

Thrust is at first born by the thrust baring in the engine shell, just is delivered on the hull from engine shell then, normally is delivered on the hull bottom at driving engine place.

For example be provided with so-called thrust blade or hill holder in the thrust baring scope between engine shell and hull bottom, it connects with screw and/or is welded on engine shell and the hull bottom.The task of this thrust blade or hill holder generally is the driving engine that is used for fixing and props up in poling a boat.But it also can make special construction thrust is delivered to hull from engine shell.This thrust blade or hill holder ship vertically in can bear king-sized thrust and pulling force.

Concerning but weight can reach hundreds of ton and this big marine diesel engine of several ten thousand horsepowers of power, this thrust blade or hill holder be must with the iron plate of the adaptive hundreds of kilogram that weighs of concrete environment in the ship.Each is adaptive pretty troublesome, and generally all needs one to multiplely time to transport these iron plates to the workshop, then transports engine house again back.

The present invention has improved this anchor fitting, does not need it is shipped troublesomely to go.

According to the present invention, this anchor fitting has the feature of independent claims 1 characteristic, and every dependent claims then is about various favourable structural shapes.

Anchor fitting of the present invention need not any accessory appliances, and also the road of part from engine house along inconvenience that need not be difficult to the weight of anchor fitting to handle is transported to the workshop, transports engine house more therefrom back.

Hull bottom is that anchor fitting is prepared one or more overdimensioned hole, and the parts of anchor fitting are that fixed muffle or thrust bush run through this hole, and inject this hole.Thrust bush can be one or more.This hole does not need accurate especially also available laser burner to go up easily alow, and cutting forms.Cooperate with sleeve and the hull bottom accurate profile bonded assembly of realizing thrust bush that pours into an integrated entity then.A bolt passes this sleeve, and its end is supported on the motor body, and the nut of its other end then directly or indirectly promptly is supported on the hull bottom by a packing ring.This packing ring can be spherical thrust washer, and the nut support that makes spherical nut is on this packing ring.Bolt makes so-called expansion bolt, promptly makes with steel and carries out prestress, so the vibration of driving engine can not cause nut loosening.

The cast thing can be with any pourable material, and this material can bear the thrust of generation and alternation load and not cause that material flowing deformation, decomposition, damage or other change, and consequently can not guarantee on the transmission of thrust and the position that driving engine is fixed on it.The cast thing that is suitable for for example has lead pure or alloy, tin, zinc, brass, bronze, but the casting resin that also available casting resin is for example strengthened or do not strengthened, as epoxy casting, obstruction spirit (Chockfast) or the like, promptly with the same material of pouring into a mould driving engine.

Cut open scheme drawing below in conjunction with the office of an example of anchor fitting the present invention is described.

Anchor fitting 1 is arranged on the engine shell body sidewall 11, and wall 11 is extended at the end 12 of engine shell from the side.The extension 12 at the end is provided with a step 13, this step 13 additionally with hold-down arm 11 ' be supported on extension 12 ' on.The hole 130,120 of step 13 and extension 12 ' have coincidence '.Driving engine standing be placed at the bottom of the driving engine 12 and hull bottom 15 between support 1215 on.Have a hole 150 on 15 alow, for example burn with laser burner or gas cutting burner in this hole, and be positioned on the extension by the cylinder in hole 130,120 ' determine.The size in this hole 150 can make pass hole 130,120 ' sleeve 16 also can be by hull bottom 15 hole 150.In the example shown, sleeve 16 has a ring set 161, and it is supported on the step 13.

Stretch out in the hole 150 that bolt 14 passes sleeve 16 and passes hull bottom 15, and tighten with a nut 141 its upper end, and this nut then is supported on the step 13 of motor body by ring set 161.Bolt 14 makes expansion bolt, so but the huge power that its elastic compensating hull produces when twisting motion and prevent to vibrate cause loosening.End and the end of sleeve 16 of the lower end of bolt 14 by bolt 14 put into a packing ring or ring washer 17 and is supported in the bottom of hull bottom 15.In an example shown, ring washer 17 is spherical thrust washer 17.Spherical nut 142 is supported in the bottom of hull bottom 15 by spherical washer 17.Certainly also can particularly suitable spherical thrust washer 17 and self-centering spherical nut 142, and adopt other packing ring-nut structure, or the length of sleeve 16 bottom selecting or do not stretch out hull bottom 15.Like this can be with a plain nut, for example directly or support to the bottom of hull bottom 15 by a packing ring.

In order with anchor fitting big thrust to be delivered to hull bottom from motor body is on the hull, and sleeve 16 should carry out profile with hull bottom 15 and be connected in the scope in hole 150, promptly pours into along sleeve 16 in the hole 150 of hull bottom 15 with cast thing 19, promptly in the space 1516.A sealing 18 can be set between the end face of sleeve 16 and spherical thrust washer 17, be used for stoping liquid cast logistics to go in the space between sleeve 16 and the expansion bolt 14.

Driving engine particularly the anchor fitting of the transmission thrust between diesel engine and the hull bottom 15 comprise a thrust bush 16, this sleeve passes the hole 130 on the motor body, 120 and a hole 150 of hull bottom 15, a back hole size is greater than the cross-sectional plane of thrust bush 16.Pour into a mould with a kind of cast thing 19 in the scope in overdimensioned hole 150 in space 1516 between the edge in the hole 150 of hull bottom 15 and the outside of thrust bush 16.A bolt 14 passes thrust bush 16, and an end is supported on the

motor body

11,13, and the other end then is supported on the hull bottom 15, and this bolt is tightened under the prestress effect.
