Bulge loop in groove and arcuate groove, the bottom edge of motor cover is circumferentially with multiple guide pin hole along it, and guide pin hole is blind hole,
Electric machine casing be provided with multiple guide pin hole the most just to guide finger, guide finger can slide in guide pin hole.
Further, the external diameter of sealing ring and the equal diameters of the first circular groove, the upper surface of sealing gasket is by introversion
The most downward-sloping inclined-plane, the lateral wall height of sealing ring is more than the height of the first circular groove.
Further, described a kind of motor cover also includes multiple alignment pin, motor with the sealing assembling structure of electric machine casing
The edge of lid is circumferentially with multiple first dowel hole along it, and it is the most right with multiple first dowel holes that electric machine casing is provided with
The second dowel hole, alignment pin insert just to the first dowel hole and the second dowel hole in.
Further, the first dowel hole is along the uniform setting of circumference of motor cover.
The present invention is by arranging sealing ring between machine shaft and motor cover so that the moisture in external environment condition cannot enter
Entering in electric machine casing, it is achieved thereby that the effective sealing between electric machine casing and motor cover, between sealing ring and motor cover being can
Dismounting connects, it is simple to changed in time after sealing ring loses efficacy, thus ensure between motor cover and electric machine casing permanently effective close
Envelope；Meanwhile, the bottom surface of motor cover is offered annular groove, arcuate groove and guide pin hole, when motor cover is installed, annular is recessed
Groove, arcuate groove and guide pin hole coordinate after being directed at the bulge loop on electric machine casing and guide finger to be inserted, and both can ensure that motor cover was pacified
The axial precision of dress, it is possible to realize the quick alignment between the screwed hole on motor cover, electric machine casing, thus improve assembling effect
Rate, in bulge loop embedded rings connected in star and arcuate groove after motor cover also can be stoped to rotate, be further ensured that assembly precision.
