Description
Technical field
The invention belongs to brushless direct current motor field, especially a kind of submarine navigation device propelling brush-less Dc motor
Machine.
Background technology
Under water, being sea water around motor, along with the increase of the degree of depth, the ambient pressure residing for motor is the biggest, its institute
The ambient pressure at place is proportional to the depth of water.After water depth reaches to a certain degree, traditional movable sealing mechanism cannot meet use and want
Ask, special sealing mechanism need to be designed.Inner shaft of motor hold axial thrust that suffered axial force includes that propeller produces and by
In the axial thrust (i.e. external and internal pressure difference is multiplied by rotating shaft net sectional area) that deep water aircraft environment hydraulic pressure produces.When aircraft exists
During diving work, during the thrust that propeller produces, affect the principal element in motor bearings life-span.Along with the depth of water residing for aircraft
Being continuously increased, the axial thrust that environment hydraulic pressure produces continues to increase, and the axial thrust that machine shaft is born the most constantly increases, sternly
Ghost image rings the service life of motor internal bearing.
Summary of the invention
It is an object of the invention to the shortcoming overcoming above-mentioned prior art, it is provided that a kind of submarine navigation device advance with brushless directly
Stream motor, it is possible to be applied in deep-sea work, has that volume is little, power is big, a feature such as high pressure resistant and life-span length.
It is an object of the invention to be achieved through the following technical solutions:
This submarine navigation device propelling brushless direct current motor, including sealing mechanism, passes through inside described sealing mechanism
Bearing is connected with the oil-filled cavity of pressure balance of regulation motor internal pressure.
Further, the oil-filled cavity of above-mentioned pressure balance includes fuel reserve tank and is arranged on the pressure balance dress of fuel reserve tank upper end
Put.
Further, above-mentioned pressure equaliser includes cylinder body, is provided with in spring, described spring one end and cylinder body in cylinder body
Portion links, and the other end links with piston.
Further, above-mentioned fuel reserve tank is cooling and lubricating fuel tank.
Further, above-mentioned sealing mechanism includes housing and movable sealing, and movable sealing is arranged on housing.
Further, the pressure within above-mentioned sealing mechanism is more than the pressure outside sealing mechanism.
Further, above-mentioned bearing is additionally provided with rotor, and the motor stator mated with described rotor.
Relative to prior art, advantages of the present invention and effect it is:
(1) motor employing sealing structure, and motor internal preliminary filling high pressure and cutting oil.Preset motor internal during assembling
Pressure is more than outside motor pressure, and this partial pressure can be used to balance the thrust that a part of propeller produces, thus reduces work
The load being used on motor bearings；Bearing and the movable sealing structure of motor internal are lubricated by cutting oil, can be significantly
Improve the comprehensive life of motor.
(2) motor is equipped with the oil cylinder of balance motor inside Yu external pressure relation.By spring, preset motor internal pressure
Poor with external pressure.Make preset pressure be multiplied by rotating shaft net sectional area equal to 50% by propeller produce thrust.So when
Aircraft is when shallow sea works, and load is airscrew thrust 50% suffered by motor bearings, according to bearing computing formula
Can show that the motor bearings theory life-span improves 8 times, it is considered to the impact of many factors, the actual raising life-span more than 6 times.Work as navigation
When device works in deep water, counteracted the axial force produced due to environment variation in water pressure, motor bearings by pressure equaliser
Life-span is substantially suitable with at shallow water, improves decades of times than the motor bearings life-span not having pressure equaliser.
