Description
Technical field
What the present invention relates to is a kind of sealing configuration peculiar to vessel.
Background technique
The driving mechanism motive sealing of the control surface such as rudder, fin is very problems of concern of its development and Design always.If it is bad that motive sealing solves, easily cause the cabin water inlet, have influence on the normal running of rudder, fin.Boats and ships or underwater hiding-machine need again to go up the depressed place dismounting when serious, again process.General motive sealing problem, such as oil cylinder, the action of piston rod is telescopic, utilizes seal ring just can realize the motive sealing of oil cylinder.Rudder stock, fin axle are different from the manner of execution of oil cylinder, the action axial rotation, and sealing mechanism is in the seawater for a long time in addition, is vulnerable to seawater corrosion, therefore need to carry out special processing, guarantee rudder, the motive sealing of fin under sea water immersion.
Summary of the invention
The object of the present invention is to provide the fin axle movable sealing structure of the long-term motive sealing problem of the control surface driving mechanisms such as the rudder that solves boats and ships or underwater hiding-machine, fin.
The object of the present invention is achieved like this:
Fin axle movable sealing structure of the present invention, it is characterized in that: comprise fin seat, casing, gland, stuffing box, axle sleeve, axle sleeve is enclosed within on the fin axle, casing is fixed on the fin seat, between casing and the fin axle bearing is installed, stuffing box, gland are installed between casing and the axle sleeve successively, be provided for adding the slit of lubricating grease between gland and the axle sleeve, thereby formation labyrinth seal, the grease inlet is set on the casing, on casing and the fin seat guide groove is set all, guide groove is communicated with the slit between gland and the axle sleeve, and the grease inlet is by the pipeline communication guide groove.
The present invention can also comprise:
1, also comprise the seepage guide groove, the seepage guide groove passes stuffing box, casing and pedestal.
2, also comprise dustproof stuffing box, thereby dustproof stuffing box is installed on the casing, is enclosed within simultaneously seal case on the fin axle.
3, the first-the 2nd O RunddichtringO is installed between casing and the fin seat and is realized static seal, the 3rd-Di five O RunddichtringOs are installed between casing and the stuffing box are realized static seal, the the first-the second U-shaped folder fabric seal ring is installed between axle sleeve and the stuffing box, the 6th O RunddichtringO and antifouling ring is installed between gland and the fin axle.
4, offer down oil groove between the slit between bearing and gland and the axle sleeve, the lubricating grease that pours into by the grease inlet passes through the injection bearing of falling the oil groove.
Advantage of the present invention is: the present invention has taked 2 kinds of dynamic sealing technologies simultaneously: packing seal, labyrinth seal.Wherein the U-shaped folder fabric seal ring of the cover of 2 in the sealed stuffing box consists of packing seal, and the lubricant grease of filling between the gland of the U-shaped folder fabric seal ring of 2 covers and the gap of axle sleeve consists of labyrinth seal, and can guarantee the lubricated of rotary bearing.In addition, even there is a little seawater to infiltrate, also can discharge by guide groove, guarantee the validity of motive sealing.Take respectively dustproof stuffing box and dust ring at the up and down two ends of casing, avoid impurity to enter, have influence on the effect of motive sealing.For guaranteeing the chronicity of motive sealing, designed the grease ascending pipe, can regularly inject grease, prevent the labyrinth seal inefficacy.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
For example the present invention is described in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1,12 is the fin axle among Fig. 1; Axle sleeve 11 tightly is enclosed within on the fin axle 12, the wearing and tearing of avoiding the long-term swing of fin to produce the fin axle.Fin seat 3 is fixed support structures of whole device.Casing 6 is fixed on the fin seat, is used for installing the accessories such as fin axle 12, lower supporting bearing 7, stuffing box 9, dustproof stuffing box 13.Because casing 6 can not rotate with respect to fin seat 3, its junction plane with fin seat 3 is static seal, therefore, has adopted 2 cover O RunddichtringOs to realize sealing.Stuffing box 9 is mainly the motive sealing that realizes the fin axle and the stuffing box that adds, this stuffing box 9 is fixed on the casing 6 from low side by bolt, and the junction plane of casing 6 has adopted 3 cover O RunddichtringOs to realize the static seal of 6 of stuffing box and casings, and the while is coated sealer with the surface of contact of fin seat 6.For preventing the bolt looseness of stuffing box 9 connect boxes, all bolt heads have carried out anti-loosening processing.Between axle sleeve 11 and stuffing box 9,2 U-shaped folder fabric seal rings 16 have been installed, the 1st U-shaped folder fabric seal ring utilizes support ring to push down, the 2nd U-shaped folder fabric seal ring withstands with gland 10, on the gland 10 of as shown in Figure 1 second U-shaped folder fabric seal ring, 1 O RunddichtringO and 1 antifouling ring have been equipped with again in addition, play sealing and antifouling effect, the surface of contact of this gland and stuffing box 9 is smeared sealer simultaneously, and be connected with stuffing box 9 with bolt, all bolt heads on the gland also carry out anti-loosening processing.Leave a little gap between gland 10 and the axle sleeve 1, lubricating grease is added in this gap, consists of labyrinth seal.Turn on spiral cover 2, by oil hole 1, utilize the oil addition pump of specialty lubricating grease can be filled in the gap between gland 10 and the axle sleeve 11, the lubricating grease of annotating in addition is filled in the lower rolling bearing 7 by guide groove 20, and rolling bearing is also played lubrication.In addition in position as shown in Figure 1, driven a thin guide groove 8, this guide groove 8 passes stuffing box 9, casing 6 and pedestal 3, like this, even because a little seepage appears in technological problems, a little seawater of seepage will be gone out by this guide groove 8, can not store in casing 6, or retaining is carried out ship inside through dustproof stuffing box 13 when too much.Be equipped with in addition the dustproof stuffing box 13 with O RunddichtringO 14 on the top of casing 6, prevented that dust from entering casing 6, and play certain seal action.
