Description
Technical field
This utility model is related to a kind of motor novel sealing structure.
Background technology
In the prior art, as shown in figure 1, the sealing of motor is all using rubber seal or close using the oil film of oils and fatss
Envelope, that is, motor enclosing cover 2 is set on motor shaft, arranges rubber seal 3 on motor enclosing cover outer face.General applied environment
Operating mode disclosure satisfy that the air-conditioning requirement of motor, but the occasion of some characteristics, such as marine climate, the torrid zone drench with rain etc. and to require motor for preventing
Shield grade reaches the operating mode of ip56, and the protection of motor just becomes problem.
Utility model content
The problem that this utility model is directed to above-mentioned prior art presence makes improvement, i.e. skill to be solved in the utility model
Art problem is to provide a kind of motor novel sealing structure, good sealing effect, adapts to the occasion of some characteristics, such as marine climate,
The torrid zone such as drenches with rain at the operating mode requiring motor degree of protection to reach ip56.
In order to solve above-mentioned technical problem, the technical solution of the utility model is: a kind of motor novel sealing structure, including
Motor shaft, motor enclosing cover, V-shaped sealing ring and curved path ring sealing member, are provided with the middle part of described motor enclosing cover and allow motor shaft to pass through
Through hole, is provided with the through hole allowing motor shaft to pass through in the middle part of described curved path ring sealing member, described motor enclosing cover outer face is arranged
There is the annular groove around through hole, described V-shaped sealing ring is arranged in this groove, and described motor enclosing cover outer face is additionally provided with
Around the annular protrusion of groove, described curved path ring sealing member is arranged on the within the chamber that this annular protrusion is formed, so that curved path ring
Sealing member is fitted with V-shaped sealing ring, so that motor enclosing cover, motor shaft, V-shaped sealing ring and curved path ring sealing member is collectively formed to electricity
The sealing structure of machine.
Further, the outer face of described curved path ring sealing member is provided with the annular flange flange around through hole, on this flange
It is provided with the fixing hole with screw, so that curved path ring sealing member is fixed on motor shaft.
Further, described curved path ring sealing member inner face is provided with projection annular slope, this annular slope interior
Footpath is more than groove external diameter, is used for blocking V-shaped sealing ring.
Compared with prior art, this utility model has the advantages that
1st, the degree of protection of motor can be improved, reach ip56；
2. reduce the requirement of the accuracy of manufacture, reduce cost；
3rd, curved path ring can conveniently be dismantled, conveniently maintenance and the low maintenance cost of valency；
4th, this programme structure is simple, workable.
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
Brief description
Fig. 1 is the organigram of original sealing structure.

In figure: 1- motor shaft, 2- old motor enclosing cover, 3- rubber seal, 4- new motor enclosing cover, 41- annular protrusion, 5-v
Type sealing ring, 6- curved path ring sealing member, 61- annular flange flange, 62- screw, 63- annular slope.
Specific embodiment
Embodiment one: as shown in Fig. 2 a kind of motor novel sealing structure, including motor shaft 1, motor enclosing cover 4, V-shaped sealing
Circle 5 and curved path ring sealing member 6, are provided with the through hole allowing motor shaft to pass through, described curved path ring sealing member in the middle part of described motor enclosing cover 4
It is provided with the through hole allowing motor shaft to pass through in the middle part of in the of 6, described motor enclosing cover outer face is provided with the annular groove around through hole,
Described V-shaped sealing ring is arranged in this groove, and described motor enclosing cover outer face is additionally provided with the annular protrusion 41 around groove,
Described curved path ring sealing member is arranged on the within the chamber that this annular protrusion is formed, so that curved path ring sealing member 6 and V-shaped sealing ring 5
Fit, make motor enclosing cover, motor shaft, V-shaped sealing ring and curved path ring sealing member collectively form the sealing structure to motor.
In the present embodiment, the outer face of described curved path ring sealing member is provided with the annular flange flange 61 around through hole, and this is convex
Fixing hole with screw 62 is provided with edge, so that curved path ring sealing member is fixed on motor shaft.
In the present embodiment, described curved path ring sealing member inner face is provided with the annular slope 63 of projection, this annular slope
Internal diameter be more than groove external diameter, be used for blocking V-shaped sealing ring.
This device passes through the combination of V-shaped sealing ring and curved path ring sealing member, constitutes dual-seal.
The foregoing is only preferred embodiment of the present utility model, all according to this utility model claim done equal
Deng change and modification, covering scope of the present utility model all should be belonged to.
