Detailed description of the invention
The heavy load that Fig. 1 can tolerate carrier-borne adverse circumstances directly turns platform structure chart.Wherein 1 is pedestal, and 2 be turntable, and 3 be electricity
Machine rotor, 4 be motor stator, and 5 be pivoting support, and 6 be magnetic coder, and 7 be liquid cooling system, and 8 be air-cooled pipeline, and 9 be sealing knot
Structure.
The enlarged drawing of Fig. 2 sealing structure.10 be washboard, and 11 be labyrinth seal, and 12 be sealing strip.
Specific embodiment
With reference to the accompanying drawing, structure example of the invention is described in detail.
The heavy load that can tolerate carrier-borne adverse circumstances directly turns the composition of platform as shown in Figure 1, by pedestal 1, turntable 2, motor
Stator 4, rotor 3, pivoting support 5, magnetic coder 6, liquid cooling system 7, air-cooled pipeline 8 and sealing structure 9 form.
It is directly turned in this example and comprehensive dielectric ring and air duct is installed inside platform, directly turning platform inner space cannot be less than
The requirement of 800mm, and the electronic equipment scale of construction driven is compared with directly turning the big several times of platform, the factors such as combination weight, protection, therefore directly
Turn platform be designed as outer-rotor structure more be suitable for.
The design of pedestal 1 turns inside platform directly, and there are the installation interfaces of comprehensive dielectric ring and air duct on 1 flange of pedestal, directly
It turns liquid cooling system 7, air-cooled pipeline 8 needed for platform, cable etc. to walk in inside, appearance is more beautiful.Design has fixed on 1 outer wall of pedestal
Position step surface, is used for the accurate location and installation of motor stator 4, and the stationary ring of pivoting support 5 is mounted on the positioning step at 1 top of pedestal
On face.
Rotor 3 is mounted on turntable 2, via the guiding role of assembly tooling, is fixed on 5 rotating ring of pivoting support together
Mounting surface on, the relative position of rotor 3 and stator is guaranteed by designing and fabricating dimension chain, it is ensured that magnetic circuit it is uniform
Property.
Under the conditions of rugged environment, feedback element is at a critical component for influencing system control precision.This example
Middle selection magnetic coder 6 as feedback element, it can be achieved that without wear measurement, by magnetic coder 6 be mounted on 5 stationary ring of pivoting support and
On 2 inner ring of turntable, herein convenient for debugging and maintenance, and directly turn platform top electronic equipment needed for dry wind via herein, make
It is ideal with environment, it is greatly improved the reliability of magnetic coder 6.
The load capacity that platform is directly turned in this example is more than 10000Nm, and more heat is generated during magnetic strength material excitation
Amount accumulates in narrow rotor 3, in 4 place cavity of motor stator, which need to select liquid cooling to take away heat.
The two-way that liquid cooling system 7 divides for parallel connection enters inside motor stator 4 all the way, for taking away the heat of loss of electric machine generation, control
The operating temperature rise of motor stator 4, rotor 3, another way are placed between motor stator 4 and pivoting support 5, and in pivoting support
5 keep certain distance, air barrier are formed, for the temperature limiting of pivoting support 5 in the reasonable scope, to be prevented environment mistake
Thermal conductivity causes 5 raceway of pivoting support stuck.Motor stator 4 is the main heater for directly turning platform, therefore uses 4 inside water of motor stator
It is cold, the sink that multiple tracks is serially connected is opened on the inside of motor stator 4, heat exchange occurs for the water flow and flume wall for flowing through sink, into
And the cooling motor stator 4 being tightly connected with flume wall, achieve the purpose that 4 radiating and cooling of motor stator.
Dry wind needed for platform top electronic equipment will directly be turned takes out all the way, is sent into motor stator 4 and rotor 3
Portion's cavity keeps the drying of inside cavity, and endlessly dry wind enters inside cavity, and inside cavity air pressure is greater than external rings
The air pressure in border forms positive pressure environment, prevents humidity, salt fog in external environment etc. from entering inside motor, under dry environment,
Motor magnetic strength material will not generate corrosion phenomenon, guarantee that motor being capable of long-lived operation with this.
Sealing structure 9 is as shown in Fig. 2, in such a way that washboard 10, labyrinth seal 11 and sealing strip 12 combine, labyrinth
Motor stator 4 and 3 internal cavity of rotor are closed as the cavity of certain crushing by sealing 11 and sealing strip 12, are prevented through anti-
Wave plate 10 stops the wave after pressure release to enter cavity, while the dry wind that air-cooled pipeline 8 is sent into uniformly being limited in the cavity
Portion forms the positive pressure of gas.Washboard 10, labyrinth seal 11 and the combination of sealing strip 12 are capable of forming multilayer pressure relief,
The effective invasion for stopping wave.
