Embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings, is easy to that this hair is well understood
It is bright, but they do not constitute restriction to the present invention.
Fig. 1 shows the feed cable axial outlet wire scheme of wheel rim motor.Wheel rim motor stator is using a kind of Embedded
Mode is arranged on the pedestal 16 of conduit 15, and cable 3 is then passed through the Axial-running Out of conduit wallboard 2 from the end of motor through motor end plate 1
Line, and complete cable 3 and motor end plate 1, the sealing of conduit wallboard 2 by watertight fittings.
Because motor stator is to be arranged on using Embedded mode in conduit, therefore motor end plate 1 and conduit wallboard 2
There is gap between mating surface, when wheel rim motor is possible to by the cooling duct of motor to enter in deepwater environment water electrode of plunging into the commercial sea
In the gap, need to carry out watertight processing to cable 3 here.
As illustrated, cable sealing device left end of the present invention is a motor end plate 1 for being provided with circular groove 17,
The half of the thickness of depth power taking generator terminal plate 1 of its further groove.Cable sealing device right-hand member is one and drives round-meshed conduit wallboard
2, herein the internal diameter of circular hole 18 must be more than the internal diameter of motor end plate grooves 17.In addition, being provided with a circle in motor end plate groove center
Shape through cables hole 11, aperture is equal to the outer diameter sheath of cable 3.
As shown in figure 3, the volume for being fluid sealant for increase vulcanizate, first boss 4 is extended at the fluting of motor end plate 1 end
And with the groove of motor end plate 1 the first watertight chamber 1 of formation, conduit wallboard tapping extend second boss 6 and with conduit wallboard
Circular hole, motor end plate 1 formation the second watertight chamber 13.Needed in the seal process of cable to the first watertight chamber 1, the second watertight
Fluid sealant is irrigated in chamber 13 and is sulfided with the metallic plate and cable cover(ing) of surrounding.
Specific installation steps are described below：
The first step vulcanizes：Cable 3 is first passed through into motor end plate 1, and make that the first watertight chamber is 1 opening up, cable 3 is in the
The center of one watertight chamber 1, it is fixed using fixture, then fluid sealant is rapidly injected into the first watertight chamber 1 until solid
Change, finally the inner/outer sheath of motor end plate 1 and motor stator be welded as a whole and is embedded in conduit 15, then by cable 3 by
Through cables hole 11 is drawn into the second watertight chamber 13, carries out second step vulcanization.
Second step vulcanizes：Second watertight chamber 13 is opening up and cable 3 is in the center of the second watertight chamber 13,
It is fixed using fixture, then fluid sealant is rapidly injected into the second watertight chamber 13 until solidifying.
In the course of the work, due to there is radial direction and tangential electromagnetic force between stator and rotor, this will necessarily evoke motor
Motor stator is in radial direction and the vibration of circumferencial direction, to ensure the sealing reliability of motor cable under operating condition, second
Enhancing boss 5 is provided with watertight chamber 13, it is processed as an entirety with motor end plate 1, so can both ensure vulcanizate and week
The adhesion strength of metallic plate is enclosed, and vulcanization area can be increased, the sealing effectiveness radially with axial direction is played.
As shown in figure 3, being the adhesion strength of further increase vulcanizate, watertightness performance is improved, in the axle of the first watertight chamber 1
The first internal thread 7 is machined with to medial surface, the second internal thread 10 is machined with the axially inner side face of the second watertight chamber, it is convex strengthening
The inside and outside side in axial direction of platform 5 is machined with enhancing internal thread 8, enhancing external screw thread 9 respectively.While pair metal contacted with vulcanizate
Planar section and cable cover(ing) part carry out frosting treatment, and uniformly smear viscose glue to the position of these frosting treatments before encapsulating
Agent.
Above-described is only the preferred embodiment of the present invention, sealing device of the present invention for multicore cable or
The sealing of many single-core cables is equally applicable.It should be pointed out that for the person of ordinary skill of the art, not departing from this hair
On the premise of bright principle, several modifications and improvements can also be made, these also should be regarded as belonging to protection scope of the present invention.
