Further, the first dowel hole is uniformly arranged along the circumference of motor cover.
This utility model is by arranging sealing ring between machine shaft and motor cover so that the moisture in external environment condition without
Method is entered 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
To be detachably connected, it is easy to be changed after sealing ring fails in time, so as to ensure having for a long time between motor cover and electric machine casing
Effect sealing；Meanwhile, annular groove, arcuate groove and guide pin hole are opened up on the bottom surface of motor cover, when motor cover is installed, by ring
Coordinate insertion after bulge loop and guide finger on connected in star, arcuate groove and guide pin hole alignment electric machine casing, can both ensure motor
The axial precision that lid is installed, the quick alignment being also capable of achieving between the screwed hole on motor cover, electric machine casing, so as to improve assembling
Efficiency, bulge loop can also prevent motor cover from rotating after being embedded in annular groove and arcuate groove, be further ensured that assembly precision.
