Description
Technical field
The utility model relates to a kind of Water Lubricated Stern Tube Bearing System, and being mainly used in high-power, major diameter axle is occasion, is stern bearing, rudder bearing as the large power ship cardan shaft.
Background technique
Stern bearing is divided into two kinds of oil lubrication and Water Lubricated Stern Tube Bearing System according to its lubricated type of cooling, and the oil lubrication stern bearing pollutes owing to its oil leak causes water, has reduced its use at present.
Stern bearing is according to using material to be divided into metallic material type and nonmetallic material type.Using scope is narrower owing to the defective of its vibration noise aspect for the metallic material stern bearing.The stern bearing nonmetallic material generally have lignumvitae, nylon, plastics and rubber bush bearing etc. several; Lignumvitae is limited by the natural resources restriction, does not re-use substantially at present.Though nylon has certain intensity and hardness, nylon has very strong moisture absorption, and suction back volumetric expansion, the material deliquescing, and intensity and wear resistance descend rapidly; The plastics class bearing has match dragon, everything can wait, and wherein matches dragon and has accounted for the suitable share in market; Water lubriucated bearing is comparatively general with rubber at present.
Small axle diameter (diameter of axle≤Φ 200mm～Φ 250mm) generally adopts solid box at present, and large-diameter (diameter of axle 〉=Φ 200mm～Φ 250mm) adopts the strip type bearing; Screw is generally adopted in circumferential location when the strip type bearing material is installed in the bearing, or fixes by its lath and lath being used for each other.The surface of contact of above-mentioned stern bearing is generally linear cambered surface.
Summary of the invention
The purpose of this utility model is to provide a kind of vibration damping, noise reduction, wear-resisting reliable, plane strip type water lubrication composite material stern bearing that the life-span is long.
To achieve these goals, the technical solution of the utility model is: plane strip type water lubrication composite material stern bearing is characterized in that: it comprises preceding baffle ring, bearing sleeve, lath, back baffle ring; Preceding baffle ring is positioned at the front-end face of bearing sleeve, and preceding baffle ring is fixedlyed connected with bearing sleeve by bolt; Back baffle ring is positioned at the ear end face inboard of bearing sleeve, and back baffle ring is fixedlyed connected with bearing sleeve by screw; Be interval with the dovetail groove in the bearing sleeve vertically, the shape of the bottom of lath is corresponding with the shape of dovetail groove, and the bottom of lath is axially wedged in the dovetail groove; Lath is positioned at the inboard of preceding baffle ring, back baffle ring.
The beneficial effects of the utility model are:
1, adopt the bottom of lath axially to wedge in the dovetail groove, when axle axially rotatablely moved, because the fixation of dovetail groove, lath can be owing to rotation is done in the effect of axle circumference frictional force; Owing to the setting of preceding baffle ring and back baffle ring, when axle had certain axial float, lath can not followed axle an axial float is taken place simultaneously.Be interval with the dovetail groove in the bearing sleeve vertically, promptly lath and lath space form groove structure between the lath, are easy to the axial circulation of bearing lubrication cooling water.Have vibration damping, noise reduction, wear-resisting reliable, efficient, energy-conservation, characteristics such as the motive sealing performance is good, non-environmental-pollution, prolongation life of equipment, mounting or dismounting maintenance are easy.
2, preceding baffle ring, back baffle ring prevent that lath from moving axially.
3, lath is made up of composite panel and nonmetal lath support, and nonmetal lath support is harder, makes things convenient for the installation and removal of lath; Composite panel is softer, can make lath have the better damping effect.
4, the bottom end of dovetail groove, lath is plane structure, is easy to the installation and removal of lath, reduces Bearing Installation, dismounting and maintains the used time.
5, the top end of lath is a plane structure, lath is a plane structure with the axle surface of contact, form polygon plane between plane strip type water lubrication composite material stern bearing and the axle 7 and contact, this design makes lubricated cooling water be easy to enter in the gap of lath and axle formation, and frictional heat is taken away; Simultaneously, bearing has less frictional loss, has reduced the power source power demand, and has been easy to oneself's adjustment of Spindle Status.
6, the end face of lath is provided with screw, two or more laths can be connected as one by bolt, thereby the bearing that adapts to different axial lengths uses.
