Abstract
The utility model provides a kind of sealing structure of electric machine stand and controller box, electric machine stand is corresponding with controller box body to open up organic block through hole, box body wiring hole is worn for wiring and connected, and sealing ring is set between the hole end surface of the aperture edge of described support through hole and box body wiring hole.Sealing ring is set between the hole end surface of support through hole and the aperture edge of box body wiring hole, prevents the surrounding materials such as dust, steam from entering in motor and controller box body, ensures that electric machine stand can be sealed reliably with the fairlead on controller.
Description
Technical field
It the utility model is related to machine field, the sealing structure of specially a kind of electric machine stand and controller box.
Background technology
In conventional motor structure, during frame manufacture directly by terminal box in the lump with support integral molding, such as cast iron
The support of part.With advances in technology, motor is notable all the more using the trend of VFC, in view of itself spy of frequency-variable controller
Point, it is more to be produced by the way of frequency-variable controller is separately machined with electric machine stand and then implement to be connected by both again, or, for
As the electric machine stand made of stainless steel material, support and terminal box, either conventional controller or frequency-variable controller are most
It is to implement to be connected again after controller is independently processed with electric machine stand, this is required in electric machine stand and controller box body
On open up through hole and worn for wiring and connected, due to lacking good sealing structure, cause the surrounding materials such as dust, steam to enter electricity
In machine and controller box body, dust is entered in motor, then can aggravate the abrasion of motor, shortens the service life of motor, if
Steam is entered in motor or in controller box, easily causes motor or controller to be damaged.
Utility model content
The purpose of this utility model is to provide a kind of sealing structure of electric machine stand and controller box, ensure electric machine stand with
Controller can be sealed reliably.
To achieve these goals, the technical scheme used for：A kind of sealing structure of electric machine stand and controller box, electricity
Machine support is corresponding with controller box body to open up organic block through hole, box body wiring hole is worn for wiring and connected, and described support leads to
Sealing ring is set between the hole end surface of hole and the aperture edge of box body wiring hole.
Compared with prior art, technique effect of the present utility model is：On the aperture side of support through hole and box body wiring hole
Sealing ring is set between hole end surface at, prevents the surrounding materials such as dust, steam from entering in motor and controller box body, is ensured
Electric machine stand can be sealed reliably with the fairlead on controller.

Embodiment
It is described in further detail with reference to Fig. 1 to 5 pairs of the utility model.
A kind of sealing structure of electric machine stand and controller box, electric machine stand 10 is corresponding with controller box body 20 to be opened up
Organic block hole 11, box body wiring hole 21 are worn for wiring and connected, the aperture of described support through hole 11 and box body wiring hole 21
Sealing ring 30 is set between the hole end surface of edge.
In such scheme, sealing is set between the hole end surface of support through hole 11 and the aperture edge of box body wiring hole 21
Circle 30, prevent the surrounding materials such as dust, steam from entering electric machine stand 10 with controller box body 20, ensureing electric machine stand 10 and control
Box body wiring hole 21 on device processed can be sealed reliably, ensure the normal work of motor and controller.
The sealing structure of electric machine stand 10 and controller box body 20 has two kinds of concrete arrangements.
First, being provided with boss 40 on electric machine stand 10, the through hole 41 opened up on the boss 40 connects with support through hole 11
Logical, the side of sealing ring 30 is resisted against on the table top of boss 40 of the periphery of through hole 41, opposite side is resisted against the aperture side of box body wiring hole 21
Hole end surface at.
Second, boss 40 is provided with the cassette bottom outer plate surface of controller box body 20, the through hole 41 opened up on the boss 40
Connected with box body wiring hole 21, the side of sealing ring 30 is resisted against on the table top of boss 40 of the periphery of through hole 41, opposite side is resisted against machine
The hole end surface of the aperture edge of block hole 11.
The arrangement of boss 40, greatly facilitate the sealing of electric machine stand 10 and controller box body 20.
Annular groove 42 is offered on the table top of boss 40, sealing ring 30 is embedded in annular groove 42, the axle of sealing ring 30
Upward thickness is more than the groove depth of groove 42.Sealing ring 30 is directly embedded into annular groove 42, easy for installation, prevents sealing ring 30
Move along the radial, ensure the sealing effectiveness of electric machine stand 10 and controller box 30.
Further, the boss 40 is cylindrical, and boss 40 is integral type with electric machine stand 10 or controller box body 20
Structure.Boss 40 is directly integrally formed with electric machine stand 10 or controller box body 20, simple in construction, and it is convenient to lay.
