Fig. 3 is the plan view of porous material rotating disc.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1, low-pressure anti-seepage device of gearbox of the present invention, comprising: gear box casing 1, the drive line 5 be arranged in housing 1, be contained in the lubricant medium 6 for lubricating transmission axle system 5 in housing 1; Be arranged on the vacuum pump 3 on housing 1 and control system 4, on the inwall being positioned at housing 1 for detect housing 1 internal air pressure pressure transducer 7 and be arranged on housing 1 top board 2 bleeder hole 9 near porous material rotating disc 8.
Vacuum pump 3 can be fixed on the outer wall of the top board 2 of gear box casing 1 by the mode of welding or be threaded.When gearbox runs, when the pressure in gear box casing 1 is greater than vacuum pump maximum working pressure value p
atime, vacuum pump 3 is started working; When the pressure in gear box casing 1 is less than vacuum pump minimum working pressure value p
btime, vacuum pump 3 quits work.Wherein, p
aand p
ball be less than ambient pressure.For example, assuming that ambient pressure is 1P, setting maximum working pressure value is 0.9P, and minimum working pressure value is 0.7P.When the pressure in gear box casing 1 reaches 0.9P, vacuum pump 3 starts to bleed, until when the pressure in housing 1 drops to 0.7P, vacuum pump quits work.Pressure in such housing 1 maintains between 0.7P-0.9P all the time.
Pressure transducer 7 is arranged on the internal face of gear box casing 1, is preferably arranged near the flask joint of housing 1 or the position of drive line, and can not lubricated medium submergence.The atmospheric pressure value detected for detecting the air pressure in gear box casing 1, and is sent in control system 4 by pressure transducer 7.Control system 4 passes through the p of atmospheric pressure value and the setting that will receive
aand p
bvalue compares, and automatically realizes starting or stoping of vacuum pump 3.
Porous material rotating disc 8 is arranged in the inside of gear box casing 1, is positioned at and has certain intervals position below the bleeding point 9 with vacuum pump 3 and be suspended in a rotatable manner on the internal face of top board 2 by support etc.As shown in Figure 2, porous material rotating disc 8 comprises the pedestal 10 being equiped with porous material 14, the transmitting assemblies 12 being located in the running shaft 11 on pedestal 10 and being arranged on running shaft 11, and the motor of vacuum pump 3 drives porous material rotating disc 8 synchronous axial system by transmitting assemblies 12.Transmitting assemblies can comprise gear, bearing, worm and gear, coupling (not shown) etc., but is not limited thereto.Porous material 14 is fine pore material and has multiple suction port.When vacuum pump 3 is bled, the lubricant oil picked up can be adsorbed onto on the porous material 14 of porous material rotating disc 8, and the lubricant oil be adsorbed on porous material 14 can be thrown in gear box casing 1 by centrifugal force when utilizing porous material rotating disc 8 to rotate.So both avoid vacuum pump 3 and lubricant oil is extracted in external environment condition the waste causing lubricant oil, also avoid befouling environment simultaneously.
In gearbox runs, the chamber pressure of housing 1 constantly increases, and the atmospheric pressure value detected is sent in control system 4 by pressure transducer 7, when pressure reaches p
atime, control system 4 sends actuating signal to vacuum pump 3, vacuum pump 3 aspirates the inner chamber air of gear box casing 1, and simultaneously porous material rotating disc 8 rotates under the driving of vacuum pump 3, utilizes centrifugal force to get rid of in aspiration procedure to be adsorbed onto the lubricant medium 6 on porous material 14.When the chamber pressure of housing 1 is less than p
btime, control system 4 sends stop signal to vacuum pump 3.Once the chamber pressure of housing 1 is more than p
a, vacuum pump 3 will task again, thus chamber pressure is remained lower than ambient exterior atmospheric pressure.
After gearbox is out of service, owing to still having fluid at the gap location of housing 1, comprise the vacuum pump system delay working certain hour t of vacuum pump 3, control system 4 and pressure transducer 7, in order to remove the fluid resting on gap location.When gearbox quits work, the vacuum pump system comprising vacuum pump 3, control system 4 and pressure transducer 7 a period of time t that works on quits work again.So just can avoid because the rotation of housing 1 intermediate solid drive shaft system, the flowing of gas, the rotation of porous material rotating disc and the lubricant oil being attached to gap location flow in external environment condition.If when gearbox quits work, the vacuum pump system comprising vacuum pump 3, control system 4 and pressure transducer 7 quits work simultaneously, and the oil on gap may at the flows by action of the factor such as capillarity, gas flow to extraneous.So when gearbox quits work, the vacuum pump system comprising vacuum pump 3, control system 4 and pressure transducer 7 works on certain hour t, under the effect of inside and outside differential pressure, the fluid of gap location can be made to be back to enclosure interior.
Beneficial effect of the present invention is, the present invention compared with prior art, by arranging vacuum pump 3 on gear box casing 1, make the pressure in gear box casing 1 remain lower than ambient exterior atmospheric pressure, the lubricant medium of such housing 1 inside can not flow to external environment condition by the slot of gearbox; By arranging porous material rotating disc 8 in the position corresponding with the bleeding point of vacuum pump 3, lubricant medium can be prevented to be sucked in external environment condition; And by the setting of pressure transducer 7 and control system 4, realize the automatic control of startup to vacuum pump 3 and stopping.Therefore the present invention have without leakage of oil, free from environmental pollution, the advantages such as automatically control can be realized.
