Description
Technical field
The present invention relates to motor assembling field, the front motor cover assembling structure of specially a kind of totally enclosed machine.
Background technology
It is that closing is connected with electric motor end cap that totally-enclosed machine requires electric machine casing, and then plays moistureproof dust-proof effect.Existing
Some front motor covers, by being bolted on electric machine casing, lack effective sealing structure, lead to front motor cover and electric machine casing
Between, the sealing effectiveness between front motor cover and machine shaft bad, the moistureproof dust-proof effect of impact.Additionally, totally-enclosed machine exists
After work a period of time, its enclosure interior can form negative pressure, leads to the dismounting of front motor cover more difficult.
Content of the invention
For the problems referred to above, the invention provides a kind of front motor cover assembling structure of totally enclosed machine, it can solve
Sealing effectiveness between the front motor cover of existing totally-enclosed machine and electric machine casing, between front motor cover and machine shaft is bad,
And the problem that the dismounting of front motor cover is more difficult.
A kind of front motor cover assembling structure of totally enclosed machine, it includes electric machine casing and front motor cover, front motor cover
In tabular, the plate face edge of front motor cover has multiple first screws, electric machine casing offers and multiple first screws
One by one just to the second screw, bolt be arranged on just to the first screw and the second screw in fixing for front motor cover lid is located at electricity
At the front opening of casing body, front motor cover offers be available for axis hole that machine shaft passes through it is characterised in that:It also includes
Sealing ring and sealing ring, the rear end face of front motor cover offers first circular groove coaxial with axis hole, and machine shaft passes through
The bearing being arranged in the first circular groove is rotated with front motor cover and is connected, and the rear end face of front motor cover offers and the first circle
The coaxial first annular groove of connected in star, electric machine casing offers with first annular groove just to the second annular groove, close
Seal is inlaid in the cavity that first annular groove and the second annular groove are surrounded, the front end face of front motor cover offers with
The second circular groove that axis hole is coaxially disposed, sealing ring is inlaid in the second circular groove, front motor cover is close with machine shaft
Envelope, front motor cover rear end face edge offer respectively two just to wedge-shaped impression, the most advanced and sophisticated phase of described two wedge-shaped impressions
To setting, one end relative with tip of wedge-shaped impression extends to outside front motor cover.
Further, described sealing ring is band neck sealing ring, and the neck lateral wall of sealing ring offers the along its circumference
Three annular grooves, are provided with flexible collar in the 3rd annular groove and sealing ring are clamped on machine shaft.
The present invention passes through to set up sealing ring between electric machine casing and front motor cover, between machine shaft and front motor cover
Set up sealing ring so that front motor cover assembling after electric machine casing can be effectively sealed, thus prevent the external world steam,
Dust enters inside electric machine casing, prevents motor internal from making moist short circuit, extends motor service life;The rear end face of front motor cover sets
There are two relative wedge-shaped impressions, when needing to dismantle front motor cover, first bolt is unloaded, reuse two wedge cooperations and insert
Enter in two wedge-shaped impressions, so that the lower end plane of wedge is resisted against on electric machine casing, the upper end inclined-plane of wedge is resisted against wedge
On the inclined-plane of shape groove, firmly moving wedge, you can front motor cover is levered up, thus unloading front motor cover, and directly extracting electricity
Machine protecgulum is compared, more laborsaving convenience.
