Technical field
The present invention relates to a kind of all kinds of marine propulsion shafting stern pipe water sealing devices, especially a kind of jet printing type screw shaft of ship face seals of being used for.
Background technique
The relative motion surface of the sealing friction pair that traditional shock resistance axial seal device for screw shaft of ship (referring to the patent No. 200810024665.0) is constituted causes the water leakage rate to increase gradually because of the senior general that adds of wear extent; And under rugged environment in the water; For example the adaptive capacity of silt etc. is relatively poor; Reduced the life-span of stern shaft seal gland, will influence boats and ships when serious and normally navigate by water.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the existing technology, provide a kind of and have wear-resistant function, adapt to axially and the jet printing type screw shaft of ship face seals of large impact distortion operating mode radially.
According to technological scheme provided by the invention, said jet printing type screw shaft of ship face seals comprises stern tube shaft, stern base, mounting base, seal ring carriage, seal ring, supporting ring and drive chuck; Stern base, mounting base, seal ring carriage, seal ring, supporting ring and drive chuck all are enclosed within on the stern tube shaft; On mounting base, be fixed with the stern base, the first main card circle is installed on mounting base, the second main card circle is installed on the seal ring carriage; Between the first main card circle and the second main card circle, be provided with the elastic compensating body; Link to each other through adjusting screw rod between the first main card circle and the second main card circle, on the seal ring carriage, be fixed with locating stud, described seal ring is installed on locating stud; Seal ring contacts with the end face of supporting ring, on supporting ring, is fixed with described drive chuck; Between the outer wall of the inwall of mounting base and stern tube shaft, form first cooling water chamber; Between the outer wall of the inwall of seal ring carriage and stern tube shaft, form second cooling water chamber; On mounting base, offer the cooling water passage that is communicated with first cooling water chamber; With the end face of the contacted supporting ring of seal ring on circumferentially offer wear-resistant trough around it, in wear-resistant trough, be coated with wearing layer, the end face of wearing layer is concordant with the corresponding end face of supporting ring.
The degree of depth of said wear-resistant trough is 0.5 ~ 0.7mm.
On mounting base, be fixed with pressure ring, in mounting base, be fixed with the gas-flow closure body through pressure ring.At gas-flow closure body internal fixation the supporting valve is arranged, on mounting base, offer and support the air flue that valve links to each other.
Socket and be fixed with splash guard on the seal ring carriage.
The present invention is wear-resistant, and is stronger to the mal-condition adaptive faculties such as silt in the boats and ships running environment.Prolong the working life of stern shaft seal gland, reduce the frequency of maintenance of boats and ships, prolong navigation time of ship the sealing of axle system.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
As shown in the figure; This jet printing type screw shaft of ship face seals; Comprise stern tube shaft 6, stern base 3, mounting base 1, seal ring carriage 12, seal ring 13, supporting ring 15 and drive chuck 4, stern base 3, mounting base 1, seal ring carriage 12, seal ring 13, supporting ring 15 all are enclosed within on the stern tube shaft 6 with drive chuck 4, on mounting base 1, are fixed with stern base 3; The first main card circle 8 is installed on mounting base 1; The second main card circle 9 is installed on seal ring carriage 12, links to each other through adjusting screw rod 20 being provided with between the first main card circle 8 and the second main card circle 9 between elastic compensating body 7, the first main card circles 8 and the second main card circle 9; On seal ring carriage 12, be fixed with locating stud 14; Described seal ring 13 is installed on locating stud 14, and seal ring 13 contacts with the end face of supporting ring 15, on supporting ring 15, is fixed with described drive chuck 4; Between the outer wall of the inwall of mounting base 1 and stern tube shaft 6, form first cooling water chamber 2; Between the outer wall of the inwall of seal ring carriage 12 and stern tube shaft 6, form second cooling water chamber 26; On mounting base 1, offer the cooling water passage 25 that is communicated with first cooling water chamber 2; With the end face of seal ring 13 contacted supporting rings 15 on circumferentially offer wear-resistant trough 10 around it; In wear-resistant trough 10, be coated with wearing layer 11; The end face of wearing layer 11 is concordant with the corresponding end face of supporting ring 15, and the left side that in Fig. 1, is wearing layer 11 is concordant with the left side of supporting ring 15, and the groove width of wear-resistant trough 10 is greater than the contact width of seal ring 13 of position of the end face with supporting ring 15.
The degree of depth of said wear-resistant trough 10 is 0.5 ~ 0.7mm.
On mounting base 1, be fixed with pressure ring 21, in mounting base 1, be fixed with gas-flow closure body 23 through pressure ring 21.At gas-flow closure body 23 internal fixation supporting valve 28 is arranged, on mounting base 1, offer and support the air flue 24 that valve 28 links to each other.
