Abstract
The invention discloses a lubrication structure of a propeller bearing. The lubrication structure comprises a gear case with a cavity, a propeller shaft arranged on the gear case in a rotating mode, and a self-aligning bearing arranged between the gear case and the propeller shaft. A lubrication oil groove is formed in the center of the outer side of the self-aligning bearing. The gear case is provided with a lubrication oil way used for being communicated with the lubrication oil groove and the cavity of the gear case. The gear case is provided with the lubrication oil way, machine oil inside the gear case is conveyed to the middle of the self-aligning bearing, and therefore the lubricating and cooling effects are achieved.
Description
Technical field
the present invention relates to a kind of propeller bearing lubricating structure.
Background technique
rudder oar turns round transmission with two pairs of umbrella bevel gears, thereby drives blade to realize the operating mode needing; In revolution, bearing is used in a large number.In a lot of situations, the bearing lubrication situation of some position is not very desirable, thereby causes the temperature of the use of bearing to raise, finally the working life of the bearing of impact;
when selfaligning bearing is used, part perforate adds wheel lubricating oil under water again, can only utilize the machine oil of gear-box inside to be lubricated, and cooling-down effect is poor.
on gear block, increase together lubricated hydraulic fluid port, thereby reach lubrication effect, should say that this detailed design considered the actual service condition of bearing, reached quality of product demand.
Summary of the invention
the object of this invention is to provide the good propeller bearing lubricating structure of a kind of lubrication cooling effect.
for achieving the above object, the technical solution used in the present invention is: propeller bearing lubricating structure, comprise and there is inner chamber body gear-box, rotate the screw shaft be arranged on described gear-box, be arranged on the selfaligning bearing between described gear-box and described screw shaft, the center portion in described selfaligning bearing outside is provided with oil groove, is provided with for being communicated with the oil leab of the inner chamber body of described oil groove and described gear-box on described gear-box.
preferably, described selfaligning bearing comprises the bearing inner race that is fixedly installed on described screw shaft, is fixedly installed on the bearing outer ring on described gear-box.
further, on described screw shaft, be provided with interior ring gland and the axle sleeve of inside and outside two end faces that prop up respectively described bearing inner race, in the outer casing of described gear-box, be provided with outer press cover.
further, between described outer press cover and axle sleeve, adopt framework type sealing ring sealing.
because technique scheme is used, the present invention compared with prior art has following advantages:
because the present invention increases an oil leab on gear-box, the neutral position by the oil delivery of gear-box inside to selfaligning bearing, thus reach effect lubricated and cooling.
Accompanying drawing explanation
accompanying drawing 1 is cross-sectional schematic of the present invention.
in above accompanying drawing: 1, gear-box; 2, screw shaft; 3, selfaligning bearing; 4, oil groove; 5, oil leab; 6, interior ring gland; 7, axle sleeve; 8, outer press cover; 9, framework type sealing ring.
Embodiment
below in conjunction with embodiment shown in the drawings, the invention will be further described:
embodiment one: shown in accompanying drawing 1, propeller bearing lubricating structure, comprise and there is inner chamber body gear-box 1, rotate the screw shaft 2 be arranged on gear-box 1, be arranged on the selfaligning bearing 3 between gear-box 1 and screw shaft 2, the center portion in selfaligning bearing 3 outsides is provided with oil groove 4, is provided with for being communicated with the oil leab 5 of the inner chamber body of oil groove 4 and gear-box 1 on gear-box 1.
selfaligning bearing 3 comprises the bearing inner race that is fixedly installed on screw shaft 2, is fixedly installed on the bearing outer ring on gear-box 1.
the interior ring gland 6 and the axle sleeve 7 that on screw shaft 2, are provided with inside and outside two end faces that prop up respectively bearing inner race, be provided with outer press cover 8 in the outer casing of gear-box 1.
between outer press cover 8 and axle sleeve 7, adopt framework type sealing ring 9 sealings.
above-described embodiment is only explanation technical conceive of the present invention and feature, and its object is to allow person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
