Specific embodiment
Further describe the technical solution of the utility model below in conjunction with the accompanying drawings, but claimed scope is not limited to
Described.
As shown in figure 1, a kind of hydraulic accumulator for lubricating oil oil supply system described in the utility model, including housing 2,
Base cover 7, lid 8 and piston 5, described base cover 7 and lid 8 are separately mounted to bottom and the top of housing 2, described piston 5
It is placed in inside housing 2, and housing 2 inner chamber is separated into lubricating cavity 13 and air chamber 14, in described air chamber 14, be provided with spring
4, the upper end of described spring 4 is connected with piston 5, and lower end is sleeved on the spring base 6 being arranged in base cover 7.Spring base 6, if
Put the center in base cover 7, spring 4 is located at housing central section, and the centrage of spring 4 and housing central axes it is ensured that
Spring 4 uniform force.It is assemblied in the oil feed line in engine lubrication system using the hydraulic accumulator described in the technical program
In, provide lubricating oil to engine bearing for electromotor under the effect of zero-g, nearly zero-g and minusg, it is to avoid in electromotor
Not enough in the oil lubrication of zero-g, nearly zero-g and minusg operating mode lower bearing, improve the functional reliability of electromotor and fly
The flight safety of machine.
Lubricating oil inlet pipe joint 1 and oil outlet pipe joint 9 are respectively arranged with described lid 8.Lubricating oil inlet pipe joint 1
It is connected so that lubricating oil enters the lubricating cavity 13 of housing 2 by lubricating oil inlet pipe joint 1 for being pressurized catheter pump with lubricating oil adnexa
Interior；Oil outlet pipe joint 9 is used for for the lubricating oil in lubricating cavity 13 being input into lubrication engine bearing after electromotor.
It is provided with connection for breather pipe 12 in described base cover 7.Connection for breather pipe 12 is connected to electromotor by exterior line
Ventilating system, after air enters into engine accessory power rating casing, drains into air by the valve of eccentric contract.
Described base cover 7 and lid 8 are connected with the lower end of housing 2 and upper end by stud 10 respectively, and pass through nut 11
Locking.Connected using stud nut, dismantle and easy for installation, low cost of manufacture.
