Abstract
The utility model belongs to the technical field of boats and ships, a tilting type lobe end face seal device is related to, including being used for installing the casing on the cabin wall, set up rand, membranous disc inner circle in the casing hole, rand and membranous disc inner circle fixed connection, rand hole and axle fixed connection set up the second sealing washer between membranous disc inner circle and the axle, and the cooperation sets up the membranous disc outer lane on the outer periphery of membranous disc inner circle, and the cavity of casing is placed in to the membranous disc outer lane. The utility model is suitable for an all kinds of ship shafting's lobe is sealed, adopts novel structure, can avoid the membranous disc to produce the relative slip and cause wearing and tearing on an operation in -process and a surface to satisfy and to turn round for a long time, reliably under arbitrary angle of shafting declivity state, play good sealed effect, and the will not damages because of the deflection of shafting.
Description
Technical field
This utility model belongs to technical field of ships, is related to a kind of tilting division end face sealing device.
Background technology
As division end face sealing device, watertight should be able to be all played in the case where the arbitrary cabin in ship division wall both sides intakes
Envelope is acted on, and prevents water from entering another cabin.
Existing division end face sealing device, membranous disc are sleeved on axle, realize film by the O-ring seals in membranous disc groove
Water-stop between disk and axle surface；Membranous disc is under the thrust of the arbitrary side hydraulic pressure of bulkhead so as to end face and case inside
End face is adjacent to, and is automatically prevented from water and is flowed to bulkhead opposite side by end clearance, so as to realize shafting between ship division room
Water-stop.Due between ship axle and bulkhead and out of plumb, having a small angle, therefore when mounted, needing configuration one
The specific pinboard of block, and shafting, under by thump deformation tilt state, running effect is poor.
The content of the invention
This utility model is directed to the problems referred to above, there is provided a kind of tilting division end face sealing device, the sealing device energy
Run well under arbitrary angle of shafting declivity state.
According to the technical solution of the utility model：A kind of tilting division end face sealing device, it is characterised in that：Including
For the housing on cabin wall, collar, membranous disc inner ring are set in shell inner hole, the collar is fixed with membranous disc inner ring and connected
Connect, collar endoporus is fixedly connected with axle, the second sealing ring is set between membranous disc inner ring and axle, is matched somebody with somebody on the outer circumference surface of membranous disc inner ring
Close and membranous disc outer ring is set, membranous disc outer ring is placed in the cavity of housing.
As further improvement of the utility model, it is connected by trundle between the collar and membranous disc inner ring.
As further improvement of the utility model, mating spherical surfaces, film between the membranous disc inner ring and membranous disc outer ring, are adopted
First sealing ring is set between disk inner ring and membranous disc outer ring.
As further improvement of the utility model, alignment pin is set on the housing.
It is of the present utility model to have technical effect that：This utility model is applied to the separation of various ships shafting and seals, and adopts
New structure, can avoid membranous disc in operation process with the relative slip of generation of axle surface and cause abrasion, and meet can be arbitrary
Can for a long time, reliably operate under angle of shafting declivity state, play good sealing function, and will not damage because of the deflection of shafting
It is bad.
Description of the drawings
Fig. 1 is structural representation of the present utility model.

Fig. 3 is this utility model heeling condition schematic diagram.
Fig. 4 is this utility model normal condition schematic diagram.
Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is further described.
It is in Fig. 1 ~ 4, close including collar 1, alignment pin 2, housing 3, trundle 4, membranous disc outer ring 5, the first sealing ring 6, second
Seal 7, membranous disc inner ring 8, axle 9 etc..
As shown in Fig. 1 ~ 4, this utility model is a kind of tilting division end face sealing device, including for installed in ship
Housing 3 on bulkhead, arranges collar 1, membranous disc inner ring 8 in 3 endoporus of housing, the collar 1 is fixedly connected with membranous disc inner ring 8, is blocked
Enclose 1 endoporus to be fixedly connected with axle 9, the second sealing ring 7 is set between membranous disc inner ring 8 and axle 9, on the outer circumference surface of membranous disc inner ring 8
Membranous disc outer ring 5 is equipped with, membranous disc outer ring 5 is placed in the cavity of housing 3.
It is connected by trundle 4 between collar 1 and membranous disc inner ring 8.
Mating spherical surfaces are adopted between membranous disc inner ring 8 and membranous disc outer ring 5, between membranous disc inner ring 8 and membranous disc outer ring 5, first is arranged
Sealing ring 6.
Alignment pin 2 is set on housing 3.
The course of work of the present utility model is as follows：Housing 3 is installed on cabin wall, and collar 1 is connected firmly in axle 9 by bolt
On, collar 1 drives membranous disc inner ring 8 and membranous disc outer ring 5 with 9 synchronous axial system of axle by trundle 4, and 5 both ends of the surface of membranous disc outer ring can be divided
The sealing friction pair with water-stop function is not formed with 3 inner side both ends of the surface of housing.When the arbitrary cabin in bulkhead both sides intakes,
Membranous disc inner ring 8 and membranous disc outer ring 5 are adjacent to another side end face in housing under the thrust of hydraulic pressure, and automatism isolation water is to another
Flow in cabin.
Collar 1 drives membranous disc inner ring 8 and membranous disc outer ring 5 to make synchronous axial system with axle 9, reduces the second sealing ring 7 and first
The abrasion of sealing ring 6, extends service life, improves the sealing property of device.
It is mating spherical surfaces between membranous disc inner ring 8 and membranous disc outer ring 5, when shafting is due to one angle of reason deflection such as being impacted
When spending, tight membranous disc inner ring 8 is deflected with axle, and membranous disc outer ring 5 still keeps being brought into close contact with 3 inner face of housing, seals separation
Device still plays good sealing function, and will not damage because of the deflection of shafting.
Housing 3, membranous disc inner ring 8, membranous disc outer ring 5 and collar 1 in this utility model adopts Hafu-type structure, by bolt
Connect as one with taper pin, be easy to ship emergency maintenance and replacing under boat state.
As shown in Figure 3, tilting division end face sealing device can compensate for 10 ° of shafting inclination maximum, now sealing dress
Put sealed reliable.
