Description
Technical field
The present invention relates to a kind of adjusting center screw shaft bearing apparatus for boats and ships tail end.
Background technique
Propeller cavitation is the visual plant of marine propuision system, and screw shaft bearing apparatus is for supporting the moiety by weight of propeller cavitation and axle system.Existing ship propeller bearing is made up of axle sleeve and the rubber strip that is arranged on inner hole of shaft sleeve, bearing be fixedly mounted in bearing support with tailing axle phase configuration.Because propeller cavitation sole mass is larger, and be arranged on tailing axle end portion, tailing axle end becomes cantilever-shaped, easily occur bending and deformation, and existing bearing maintains static, therefore easily make bearing contact with tailing axle in the axial direction uneven, cause local specific pressure bigger than normal, form " edge loading " phenomenon, cause bearing concentrated wear excessive, thus reduce bearing working life; And " edge loading " phenomenon makes cannot form good lubricating film between axle and bearing, produce dry friction and creeping phenomenon, cause pivot friction self-excited vibration, and then generation whistle, particularly when frictional vibration frequency is consistent with axle system or hull local frequencies, axle system or the resonance of hull partial structurtes can be caused, thus produce strong vibration noise, affect the recessive energy of sound on naval vessel.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of adjusting center screw shaft bearing apparatus, and it can improve the contact condition of propeller bearing and tailing axle, reduces wear, and improves usability and the life-span of propeller bearing, and reduces noise.
The technological scheme that the problem that the present invention is the above-mentioned proposition of solution is taked is: comprise bearing support, be arranged on the propeller bearing of described bearing support inner chamber, it is characterized in that being installed on aligning bearing sleeve between bearing support lumen orifice seat and propeller bearing, described aligning bearing sleeve comprises periphery and arranges the outer bearing sleeve that the interior bearing sleeve of sphere and endoporus arrange corresponding ball seat, interior bearing sleeve is set in outer bearing sleeve endoporus, the periphery sphere of interior bearing sleeve and the ball seat phase configuration of outer bearing sleeve.
By such scheme, the periphery sphere of described interior bearing sleeve is outer convex spherical, and the ball seat of described outer bearing sleeve is indent ball seat.
By such scheme, described interior bearing sleeve endoporus and the periphery phase configuration of propeller bearing, described outer bearing sleeve periphery and bearing support lumen orifice seat phase configuration.
By such scheme, described outer bearing sleeve is formed by two involutory connections of semicircular bearing shell.
By such scheme, described interior bearing sleeve evagination spherical diameter is greater than interior bearing sleeve outer circumference diameter, and interior bearing sleeve evagination spherical diameter is less than interior bearing sleeve axial length.
By such scheme, described outer bearing sleeve indent ball seat spherical diameter is identical with interior bearing sleeve evagination spherical diameter, and outer bearing sleeve indent ball seat spherical diameter is less than outer bearing sleeve outer circumference diameter.
By such scheme, described outer bearing sleeve indent ball seat sphere and the outer same centre of sphere of convex spherical of interior bearing sleeve, and the centre of sphere is positioned on the axis of described propeller bearing, described outer bearing sleeve indent ball seat area of spherical surface is less than interior bearing sleeve evagination area of spherical surface.
By such scheme, the outer convex spherical of described interior bearing sleeve is provided with oil groove, and described outer bearing sleeve indent ball seat ball correspondence offers the oilhole be connected with lubricant pipe.
By such scheme, described interior bearing sleeve and outer bearing sleeve are made up of ZCuAl10Fe3 material.
Beneficial effect of the present invention is: 1, by arranging aligning bearing sleeve, make propeller bearing can do the swing fine setting of any direction, realize it with axle condition self-aligning function, propeller bearing is made to keep even contact with tailing axle in the axial direction, which not only improves the usability of propeller bearing, and can reduce wear, extend bearing working life, reduce and avoid the generation of noise, be also convenient to the installation of tailing axle and propeller bearing simultaneously; 2, by the regular pressure injection launching grease of lubricating oil pipeline, stored in oil groove, realize aligning bearing sleeve sphere lubrication in the seawater and antirust, thus ensure the aligning function of aligning bearing sleeve; 3, the aligning bearing sleeve be made up of ZCuAl10Fe3 material has stronger wear-and corrosion-resistant ability, thus ensures further aligning bearing sleeve working life in the seawater.
