Specific embodiment
As shown in Figures 1 to 3, the invention proposes a kind of fire-proof motor, including end cap 1, shaft 2, casing 3 and sealing element 4,
In a tubular form, corresponding its edge of casing 3 of end cap 1 is rounded for casing 3, and the center of end cap 1 is equipped with the axis hole for penetrating end cap 1, axis
Hole gradually reduces from inside to outside, and side wall is stepped, reduces the internal diameter of axis hole step by step from inside to outside, outermost level-one
Matched with the axle body of shaft 2, and be equipped with a ring around the shaft 2 groove 11, shaft 2 is equipped with a circle respective slot 11 and opens
The annular groove 21 of mouth position, the inward flange of sealing element 4 cover at the annular groove 21 of shaft 2, the profile of outer edge respective slot 11
Extend in groove 11, the gap outside motor can be led to by making between axis hole and shaft 2 is truncated, and the inward flange of sealing element 4 and
Outer edge extends respectively to the inside of shaft 2 and end cap 1, and load performance is good, is able to bear internal blast pressure and will not damage
It loses, while preventing spark arc from traveling to outside casing 3.To reach good flame proof effect.
As shown in Fig. 4 to 5, in the present invention, end cap 1 and casing 3 use double stopper structure, and the end face of end cap 1 is equipped with a circle
First concave mouth 111, the bottom surface of the first concave mouth 111 is provided with the second concave mouth 112, and the gap of the second concave mouth 112 is small
In the gap of the first concave mouth 111, the end of casing 3, which is equipped with, can be inserted into the first of the first concave mouth 111 and the second concave mouth 112
Male half coupling 311 and the second male half coupling 312, seam allowance make end cap 1 link together with casing 3, can form electrostatic in complete annular
Wall can stop electrostatic to enter internal, protection internal electronic component, enhancing flame proof effect from outer.And match after double stopper clamping
It is high to close intensity, and better dust seal effect can be reached.
The inward flange and outer edge of sealing element 4 are located at Different Plane, are connected by inclined-plane, and joint face may be song
Face makes sealing element 4 have the bowl-type of through-hole in the center of circle, and the groove 11 of end cap 1 is divided into two sections according to the depth to 11 bottom surface of groove,
One section of setting of vertical rotation axis 2 and 11 bottom surface of communication groove, another section of outlet to inclination connection groove 11 on the outside of motor make groove
11 inner wall forms a turning by the design of two-part, and the shape of 11 opening of groove is on the outside of motor inclined one
Section, matches with inclined-plane or curved surface, and there are two types of fit systems, another one is matching with a part of inclined-plane or curved surface
Kind is matched with the whole of inclined-plane or curved surface.When sealing element 4 inward flange installation site than outer edge closer to described turn
When the end of axis 2, sealing element 4 is inwardly buckled to and is sleeved in shaft 2, the blast pressure inside motor is isolated from the outside world, together
When inclined-plane or curved surface design can reach it is certain unload power effect, reduce damage and prolong the service life, and the groove 11 on end cap 1
There are certain installation gaps to be easily installed for the thickness of opposing seal 4.
