Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
Embodiment:
nullRefer to Fig. 1 and Fig. 2，The present invention provides a kind of technical scheme: a kind of fluid pressure type bearing deafener，Including bearing base 1 and hydraulic pressure deafener 2，The upper surface of described bearing base 1 is installed with lower house 3 and upper shell 4，And lower house 3 and upper shell 4 are by tight lock screw 5 linking into an integrated entity structure，It is internal with lower house 3 that described hydraulic pressure deafener 2 is arranged on upper shell 4，And be the most all connected with housing by bolt 6，Described hydraulic pressure deafener 2 includes the first chamber volume 7、First mass room 8，Described first chamber volume 7 is positioned at top near upper shell 4，Described first mass room 8 communicates 9 with the first chamber volume，And it is connected to diplopore chamber volume 11，The other end of described diplopore chamber volume 11 connects the second mass room 12，Described second mass room 12 connects the second chamber volume 13，And second chamber volume 13 be positioned at bottom near lower house 3，Described first chamber volume 7、The junction of the first mass room 8 and the junction of the second mass room 12 and the second chamber volume 13 are bonded with plastic cement sealing ring 14，Described first chamber volume 7、The outer wall of diplopore chamber volume 11 and the second chamber volume 13 is provided with external damping layer 15；The outer wall of described first mass room 8 and the second mass room 12 all uses composite damping floor 16, described composite damping layer 16 to be restraint layer 17, internal damping layer 18, composite plate 9, anti-oil reservoir 10 from top to bottom.
nullDescribed bearing base 1 is used for fixing whole bearing，Described lower bottom cover 3 and linking into an integrated entity of upper bottom 4 seal structure，Hydraulic pressure deafener 2 within Bao Zhenging can be stablized，Described bolt 6 is for fixed hydraulic deafener 2，Described hydraulic pressure deafener 2 mainly realizes hydraulic pressure silencing function，High-speed hydraulic stream expands in entering the first chamber volume 7，Then flow through the first mass room 8、Diplopore chamber volume 11 and the second mass room 12，External damping layer 15 is utilized progressively to slow down pulsation，Reach noise reduction purpose，The flow of pressurized volume contraction expanded in the second chamber volume 13，Described composite damping layer 16 slows down impact of collision vibration，Keep deafener stable，The sealing of whole deafener strengthened by described sealing ring 14，Prevent liquid stream from leaking，Described restraint layer 17 retrains the profile of whole composite damping layer 16，Described internal damping layer 18 extends the vibration period，Described composite plate 9 improves the intensity meeting damping layer 16，Anti-oil reservoir 10 prevents liquid stream from leaking.
