Embodiment
Describe the present invention below in conjunction with accompanying drawing in detail in embodiment's mode.
Embodiment:
As shown in Figure 1, a kind of subtracting shakes gyrorotor rapid starting/stopping device, comprise hydraulic oil container, oil hydraulic pump 2, oil hydraulic motor 3, common one-way valve 6, Pilot operated check valve 7, the first relief valve 5, the second relief valve 4 and return filter 8, wherein, the first relief valve 5 is identical with the second relief valve 4 structures, oil hydraulic pump 2, oil hydraulic motor 3, common one-way valve 6, Pilot operated check valve 7, the first relief valve 5, the second relief valve 4 and return filter 8 are equipped with import and outlet, and Pilot operated check valve 7 also is provided with the oil circuit control mouth; Hydraulic oil is housed in hydraulic oil container, and oil hydraulic pump 2 is by motor 1 power supply, the output shaft of oil hydraulic motor 3 with subtract the rotor 9 that shakes gyro and be connected.
The import of oil hydraulic pump 2 is connected in hydraulic oil container, and the outlet of oil hydraulic pump 2 is connected respectively to the entrance of oil hydraulic motor 3, the entrance of the second relief valve 4 and the oil circuit control mouth of Pilot operated check valve 7.The outlet of oil hydraulic motor 3 is communicated with the outlet of Pilot operated check valve 7 and the entrance of the first relief valve 5 respectively, with the outlet of oil hydraulic pump 2, be communicated with, the outlet of the entrance of the outlet of the second relief valve 4, Pilot operated check valve 7 and the first relief valve 5 is connected respectively to the entrance of return filter 8, and the outlet of return filter 8 is connected in hydraulic oil container.The entrance of common one-way valve 6 is connected in hydraulic oil container, and the outlet of common one-way valve 6 is communicated with the entrance of oil hydraulic motor 3.
Working principle of the present invention is as follows:
When needs start gyrorotor, open motor 1, motor 1 drives oil hydraulic pump 2 rotations, make the outlet of oil hydraulic pump 2 produce oil pressure, this oil pressure is closed common one-way valve 6, simultaneously, this oil pressure is connected the oil circuit control mouth of Pilot operated check valve 7, thereby the entrance that exports to of Pilot operated check valve 7 oppositely is communicated with.Oil pressure actuated oil hydraulic motor 3 rotates, oil hydraulic motor 3 rotor drivens 9 rotations, and the fuel-displaced outlet from Pilot operated check valve 7 of oil hydraulic motor 3 flows into, and the entrance by Pilot operated check valve 7 flows back to fuel tank via return filter 8.Be provided with in the present embodiment the second relief valve 4, for guaranteeing that oil pressure that oil hydraulic pump 2 produces is not higher than system rated pressure scope, when oil pressure reaches the setup pressure value of relief valve 4, a part of hydraulic oil, by relief valve 4, flows back to fuel tank through return filter 8.
When needs are closed gyrorotor, disable motor 1, oil hydraulic motor 3 can continue rotation a period of time under the inertia kinetic energy of rotor 9 drives, and oil hydraulic motor 3 at this moment is equivalent to vacuum pump on function, in the pipeline between oil hydraulic pump 2 and oil hydraulic motor 3, produces negative pressure.Under the effect of negative pressure, common one-way valve 6 is opened, and the hydraulic oil in hydraulic oil container enters oil hydraulic motor 3 via common one-way valve 6; Simultaneously, this negative pressure disconnects the oil circuit control mouth of Pilot operated check valve 7, and Pilot operated check valve 7 is closed.Can produce high pressure in the fuel-displaced pipeline of oil hydraulic motor 3, the value of this high pressure is set up by relief valve 5.When oil hydraulic motor 3 go out the set pressure that oil pressure reaches relief valve 5 after, relief valve 5 is opened, the hydraulic oil relief valve 5 of flowing through produces amount of heat simultaneously, consumes the kinetic energy of rotor 9, and rotor 9 is shut down.Make rotor 9 shutdown needed times relevant with the set pressure value of relief valve 5.
