Description
Technical field
The present invention relates to a kind of ship power transmission system slide thrust bearing, especially a kind of pad deformation support mechanism of slide thrust bearing.
Background technique
Slide thrust bearing is generally made up of thrust axis, thrust pad, tile fragment supporting structure and housing etc.The supporting structure of thrust pad has very important effect for the equal carrier improved between the distortion of tile fragment and each tile fragment.At present, the thrust pad supporting structure used in marine thrust bearing mostly is equilibrium block supporting, balance block structure is made up of upper equilibrium block and lower equilibrium block, upper equilibrium block with between tile fragment for stiff points contacts, lower equilibrium block and bearing housing are that nonflexible line contacts, and are nonflexible line contact between upper and lower equilibrium block.Adopt equilibrium block supporting structure, can load between balanced each tile fragment, ensure the stable operation of each tile fragment.But, equilibrium block supporting belongs to rigid supporting structure, and when the pulsation thrust that marine propeller produces is to thrust axis, this pulsation thrust will by structures such as the thrust pad of rigid contact+upper and lower equilibrium block+housings, be directly passed to bearing housing, and then be delivered on hull.So equilibrium block supports the thrust calculation that can not absorb or cushion from marine propeller.And, due to the structural factor of stiff points linear contact lay, when thrust load is larger, each contacting point can produce larger resiliently deformable and skimming wear, the axial position of thrust pad is caused to change, cause Thrust ring to produce larger axial float, and equilibrium block supporting structure etc. can not compensate this axial float, therefore thrust pad working state worsens.
Summary of the invention
For the deficiencies in the prior art, the present invention proposes a kind of elastic thrust pad support mechanism with axial position adjustment function, and this elastic support structure can absorb or slow down the pulsation thrust from marine propeller, and can adjust the axial position of thrust pad.

Hydroelastic system support mechanism comprises the hydraulic oil in piston, cylinder barrel and the hydraulic pressure cavity between piston and cylinder barrel, and the top of piston to be contacted with Thrust ring by thrust pad and connects, and the bottom of cylinder barrel is arranged on bearing housing.
Hydroelastic system support mechanism comprises the hydraulic oil in piston, cylinder barrel and the hydraulic pressure cavity between piston and cylinder barrel, and the top of cylinder barrel to be contacted with Thrust ring by thrust pad and connects, and piston base is arranged on bearing housing.
When the oil pressure in the hydraulic pressure cavity between piston and cylinder barrel and thrust load balance, cylinder barrel tail end face is close to by pad and adjusting nut, closure piston center oilhole.

Piston jacket has the collar; By pipe joint connecting fluid pressuring oil pipe on piston rear end face.
The invention has the beneficial effects as follows:
(1) owing to adopting hydroelastic system supporting form, be delivered on bearing housing to the pulsation thrust " elasticity " that marine propeller can produce by this supporting structure, from the thrust calculation of marine propeller by after this yielding support, can be absorbed or retarded.This hydroelastic system supporting structure also can play certain attenuation to marine propulsion shafting extensional vibration.
(2) axial position of thrust pad can adjust when shutting down or keep in repair, and operation more for convenience; After adjusting, the axial position of tile fragment can keep relatively constant when normal work, thus makes the running state that thrust-bearing keeps more satisfactory.
(3) when hydraulic system can not work or thrust load is excessive, hydroelastic system supporting will be lost efficacy, and pistons end and cylinder barrel rigid contact, still can ensure thrust-bearing normally transmitting thrust load.
Slide thrust bearing of the present invention adopts this elastic thrust pad support mechanism with axial position adjustment function, the axial position of thrust pad can be adjusted easily, make the working state that thrust pad keeps more satisfactory, and can absorb or slow down the pulsation thrust from marine propeller by yielding support, reach and reduce the object that pulsation thrust is delivered to hull.

Embodiment
Below in conjunction with accompanying drawing and embodiment, one step explanation is done to the present invention.
As Fig. 1, shown in 2, elastic thrust pad support mechanism with axial position adjustment function of the present invention, be made up of hydroelastic system support mechanism 2 and thrust pad axial position regulating mechanism 5, comprise housing 1, hydroelastic system support mechanism 2, thrust pad 3, Thrust ring 4, thrust pad axial position regulating mechanism 5, adjusting nut 6, pad 7, slide bar 8, pipe joint 9, spring 10, cylinder barrel 11, the collar 12, piston 13, joint 14 etc.
Hydroelastic system support mechanism 2 front end is connected with the thrust pad 3 contacted with Thrust ring 4, and rear end coupling shaft is to position adjusting mechanism 5.
Thrust pad axial position regulating mechanism 5 comprises slide bar 8, spring 10, pad 7 and adjusting nut 6, and slide bar 8 and spring 10 are placed in the through hole of hydroelastic system support mechanism 2 afterbody, and slide bar 8 afterbody is equipped with pad and adjusting nut 6.
Hydroelastic system support mechanism 2 comprises the hydraulic oil in piston 13, cylinder barrel 11 and the hydraulic pressure cavity between piston 13 and cylinder barrel 11, and the top of piston 13 is contacted with Thrust ring 4 by thrust pad 3 and connects, and the bottom of cylinder barrel 11 is arranged on bearing housing 1.Or the top of cylinder barrel 11 is contacted with Thrust ring 4 by thrust pad 3 and connects, and is arranged on bearing housing 1 bottom piston 13.
When oil pressure in hydraulic pressure cavity between piston 13 and cylinder barrel 11 and thrust load balance, cylinder barrel 11 tail end face is close to by pad 7 and adjusting nut 6, closure piston 13 center oilhole.
Cylinder barrel 11 overcoat has the collar 12; By pipe joint 9 connecting fluid pressuring oil pipe on cylinder barrel 11 ear end face.Or piston 13 overcoat has the collar 12; By pipe joint 9 connecting fluid pressuring oil pipe on piston 13 ear end face.
Hydroelastic system support mechanism 2 is realized by the hydraulic pressure cavity between piston 13 and cylinder barrel 11, and the area of hydraulic pressure cavity can require to design according to thrust load size and oil pressure.The axial position adjustment of thrust pad 3 is realized by the hydraulic pressure cavity thickness (i.e. the position of piston) between adjustment piston 13 and cylinder barrel 11, rotating adjusting nut 6, slide bar 8 can be made to move forward and backward, reach the object of the position of regulating piston 13.The thrust that propulsion device produces is applied on thrust pad 3 by Thrust ring 4, passes to piston 13 by thrust pad 3.When this hydroelastic system support mechanism 2 normally works, the hydraulic oil jack-up piston 13 in hydraulic pressure cavity, piston 13 end is not contacted with cylinder barrel 11, and the thrust on piston 13 passes to cylinder barrel 11 by by the hydraulic oil in hydraulic pressure cavity, finally passes on housing 1.Thus, between thrust pad 3 and housing 1, add an elasticity oil pocket link, can absorb or slow down from angle of rake thrust calculation.And each hydraulic pressure cavity communicates with one another, all carrying between each thrust pad 3 can be ensured.If hydraulic system can not work or thrust load is excessive, hydroelastic system supporting was lost efficacy, and piston 13 end directly contacts with cylinder barrel 11, is delivered on housing 1 thrust load " rigidity ", also can ensures that thrust-bearing normally works.
When the oil pressure in hydraulic pressure cavity and thrust load balance, cylinder barrel 11 tail end face is close to by the pad 7 in thrust pad axial position regulating mechanism 5 and adjusting nut 6, and piston 13 center oilhole is closed.Therefore, rotating adjusting nut 6 just can adjust the axial position of slide bar 8 and piston 13, namely adjusts the thickness of hydraulic pressure cavity, reaches the object of the axial position of adjustment thrust pad 3.
