Abstract
The utility model provides a prevent motor end cover of shaft current, it not only can solve the technical problem that current motor end cover easily formed the shaft current, can also solve the technical problem because of the oscillation generation noise. It includes lid, its characterized in that: the lid includes outer lid and threaded connection in the inner cover body of outer lid middle part, inner cover body follows shaft hole and mounting groove that the axial was equipped with mutual intercommunication, and last the moulding plastics of inner cover body is formed with the insulating bearing frame of cladding mounting groove, shaft hole inner peripheral surface, be equipped with the perforation of slot -Filler and intercommunication slot -Filler and insulating bearing frame inner chamber on the outer peripheral face of inner cover body lower part, insulating bearing frame is formed with and slot -Filler, perforation complex packing portion and connecting portion.
Description
Technical field
The utility model is related to electric motors, and in particular to a kind of End cover for motor of anti-shaft current.
Background technology
Existing End cover for motor offers bearing chamber in centre, and bearing chamber is used to installing bearing, but this motor
End cap lacks the design of anti-shaft current, and shaft current is easily formed between End cover for motor, bearing and rotating shaft, and shaft current can be serious
The service life of bearing and motor is affected, there is potential safety hazard in use, reliability is relatively low.Some End cover for motor
Insulating sleeve is installed in the inwall nesting of bearing chamber, insulating sleeve is fixedly connected by flange and projection with end cap, the knot
Structure not only assembles relatively complicated, higher to the fitted position requirement of each part, and insulating sleeve, flange and End cover for motor
Gap is also easy to produce between faying face, because vibration produces noise when causing electric motor operation.
Utility model content
For the problems referred to above, the utility model provides a kind of End cover for motor of anti-shaft current, and it can not only be solved
Existing End cover for motor easily forms the technical problem of shaft current, moreover it is possible to solve because vibration produces the technical problem of noise.
Its technical scheme is such, and it includes lid, it is characterised in that：The lid includes outer cover and threaded connection
In the inner cap body of outer cover middle part；
The inner cap body is provided with vertically the axis hole and mounting groove being interconnected, and injection in the inner cap body is formed with cladding
The insulated bearing pedestal of the mounting groove, axis hole inner peripheral surface；
The inner cap body lower, outer perimeter face is provided with the perforation of filling slot and connection filling slot and insulated bearing pedestal inner chamber,
The insulated bearing pedestal is formed with the filling part and connecting portion coordinated with the filling slot, perforation.
Further, the inner cap body top is provided with external screw thread, bottom and is provided with step surface, the outer cover top be provided with
The internal thread of the external screw thread cooperation, bottom are provided with the seam coordinated with the step surface.
Further, the perforation is respectively arranged at two ends with bellmouth tapered from outside to inside, and the height of the bellmouth is
/ 2nd of perforation height.
End cover for motor of the present utility model, inner cap body is provided with vertically the axis hole and mounting groove being interconnected, inner cap body
Upper injection is formed with cladding mounting groove, the insulated bearing pedestal of axis hole inner peripheral surface, it can be ensured that insulated bearing pedestal is tight with mounting groove
Laminating, it is to avoid the generation in gap, and then avoid because vibration produces noise；Perforation and the setting of filling slot, enable to shaft insulation
The filling part and connecting portion coordinated with filling slot, perforation is formed during being seated against injection mo(u)lding, it is possible to increase insulation bearing
Seat supports the bonding strength of mold insert with bearing chamber；Inner cap body is threadedly coupled with outer cover, is easy to damage laggard in insulated bearing pedestal
Row quick-replaceable.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
As shown in figure 1, it includes lid, lid includes the outer cover 1 and inner cap body 2 of threaded connection, and inner cap body top sets
There are external screw thread, bottom to be provided with step surface, outer cover top is provided with the internal thread that coordinates with external screw thread, bottom and is provided with and matches somebody with somebody with step surface
The seam 6 of conjunction；Inner cap body 2 is provided with vertically the axis hole 8 and mounting groove 9 being interconnected, and injection in inner cap body 2 is formed with cladding peace
The insulated bearing pedestal 3 of tankage 9, the inner peripheral surface of axis hole 8；The lower, outer perimeter face of inner cap body 2 be provided with filling slot 4 and connection filling slot and
The perforation 5 of insulated bearing pedestal inner chamber, insulated bearing pedestal is formed with the filling part and connecting portion coordinated with filling slot, perforation, perforation
Bellmouth tapered from outside to inside is respectively arranged at two ends with, the height of bellmouth is 1/2nd of perforation height.
7 is location hole in figure, is easy to End cover for motor to assemble with the positioning of motor base (frame).
