Abstract
The utility model relates to a ship oil lubrication sealing device, in particular to the improvement of the lip-type sealing ring of an oil lubrication sealing device, comprising a head part, a waistpart and a lip part which form a whole; the inner side of the lip part is provided with a spring groove and the outer side of the lip part is provided with a lip opening; and one side of a rear bezelis provided with a radial plane. The lip-type sealing ring convenient for axial supporting of a supporting plate stops the lip-type sealing ring to move backwards, thus improving the anti-seawater pressure performance of the lip-type sealing ring.
Description
Technical field
The utility model relates to ship oil lubricating sealing device, relates in particular to the improvement of lip-type packing in the lubricated sealing device of oil.
Background technique
Lubricated sealing device of oil is one of boats and ships seal arrangement commonly used, is widely used in the sealing of screw shaft of ship and electronic pusher cardan shaft, and the quality of its sealability directly has influence on the safe operation of boats and ships, is one of vitals of boats and ships.Present lubricated sealing device of oil is made of the lip-type packing that is fixedly installed to the sealing seat on the hull and also fixed by the sealing seat clamping (the hot Rec department seal ring that sprinkles).
Lip-type packing is made by rubber, deformation takes place easily, when the seawater pressure of one side of the basil before the lip-type packing (hereinafter to be referred as the front side) is excessive, lip-type packing meeting generation deformation, the basil one side (hereinafter to be referred as rear side) moves after lip-type packing, make lip not malleation on running shaft (or axle sleeve), cause sealability to descend, thereby the lip that the lubricant oil in the oil pocket that is made of lip-type packing rear side and sealing seat removes lip-type packing partly provides lubricated, prevent outside dry grinding and the heat radiation, also the rear side to lip-type packing provides the pressure opposite with seawater pressure, moves after stoping lip-type packing axially.But the oil pressure of oil pocket is not easy and sea water pressure balance in the actual motion, and the lip of existing lip-type packing is not easy to axially support, thereby the sealability of cunning profit seal arrangement when seawater pressure is big be not fine, still finds no the solution or the data of effect at present.
The model utility content
At the existing above-mentioned deficiency of existing lip-type packing, technical problem to be solved in the utility model is that a kind of lip-type packing of being convenient to axially mounting will be provided, to make things convenient for the lip-type packing of dunnage axially mounting, move after stoping lip-type packing axially, thus the performance of the anti-seawater pressure of raising lip-type packing.
In order to solve the problems of the technologies described above, the scheme of the utility model technical solution problem is: a kind of lip-type packing of being convenient to axially mounting, comprise and be linked to be whole head, waist and lip, the inboard of described lip is provided with spring groove, the outside of described lip is provided with lip, and the basil one side is provided with plane radially behind the described lip.
After adopting such scheme, owing to the plane that is provided with at lip-type packing lip rear side radially, thereby the dunnage that is fixed on the annular that is positioned at the lip-type packing rear side on the sealing seat can contact and axially mounting with the corner of lip-type packing waist rear side and the place, radial plane of lip rear side, can either stop lip-type packing backward side shaft to displacement, improve the performance of lip-type packing sea water resistance pressure, do not influence lip-type packing waist and lip moving radially among a small circle again, make the followability of lip-type packing unaffected substantially; Simultaneously, because lip-type packing is subjected to the dunnage supporting, can resist seawater pressure preferably, thereby can reduce oil pressure in the oil pocket, and the stability of oil pressure and the requirement of following the tracks of the sensitivity of seawater pressure descended to some extent, thereby can save the cost of oil pressure control aspect, and oil pressure descends and to be not easy to cause lubricant oil to leak into the sea from the lip of lip-type packing, can reduce pollution the ocean.
The plane radially of the basil one side is the plane of annular behind the lip-type packing lip.
Description of drawings:
The lip-type packing of the utility model being convenient to axially mounting below in conjunction with the drawings and specific embodiments further describes.
Fig. 1 is the cross section structural representation of the utility model lip-type packing of being convenient to axially mounting;
Fig. 2 is the structural principle schematic representation that lip-type packing that the utility model is convenient to axially mounting is applied to lubricated sealing device of oil.
Embodiment
Among Fig. 1, Fig. 2, the lip-type packing of being convenient to axially mounting is an overall structure, and the lip 1 that arc waist 4 links to each other with waist 4 that is that is linked to each other with head 3 by head 3 constitutes.The inboard of lip 1 is a spring groove 2, and the outside is a lip 7, and rear side is provided with plane 6 radially, and this plane 6 is the plane of annular.Sealing seat 8 all adopts boss structure to connect together mutually each other and between sealing seat 8 and the dunnage 11, and with bolt tightening (bolt does not draw among the figure), to guarantee installation precision.The head 3 of lip-type packing is equipped with stainless steel spring 13 by sealing seat 8 clampings and fixing in the spring groove 2 of lip-type packing lip 1, is used for waling lip 1, and makes lip 7 be close to the surface of axle sleeve 12, seals, and enters to stop seawater.Dunnage 11 is positioned at the lip-type packing rear side, and contact with the corner 5 of lip-type packing waist 4 and with the plane 6 axially spaced-apart 2mm of the annular of lip 1 rear side, after stoping lip-type packing axially, move past greatly, lip 7 is moved radially among a small circle, thereby improve the performance of the anti-seawater pressure of lip-type packing, the rear side of lip-type packing and sealing seat 8 common formation oil pockets 10, be full of lubricant oil (advancing of oil pocket 10 in the oil pocket 10, do not draw among the oil out port figure), for the lip 7 of lip-type packing provides lubricated, prevent dry grinding and heat radiation, owing to rely on dunnage 11 to stop lip-type packing deformation, thereby the oil pressure in the oil pocket 10 can be provided with lowlyer, and save the oil pressure control apparatus of complexity when relying on oil pressure opposing seawater pressure, lubricant oil leaks into the possibility in sea when also having avoided oil pressure to be higher than seawater pressure from lip 7, minimizing is to the pollution of ocean, because the plane 6 of the annular of lip 1 rear side is less with the radial distance of lip 7, lip-type packing can be resisted bigger seawater pressure under the supporting of dunnage 11.
Dunnage 11 has through hole 9 on the position corresponding with lip-type packing waist 4, be convenient to lubricant oil and circulate throughout and dispel the heat.
The another lip-type packing is standby circle among Fig. 2.
