A Double-lip framework oil sealing, sets circle convex platform on the outside of end cap, and two Double-lip framework oil sealings are set in circle convex platform inside parallel,
Spacer ring is set between two Double-lip framework oil sealings, and the spacer ring is arranged on circle convex platform medial surface.The utility model
Band oil enveloping structure wheel hub motor, double oil seal structure is set on the outside of end cap end bearing, and between being set between two oil sealings
Every, can effectively stop moisture penetrate into, ensure the normal use of equipment and prolong the service life.
Further, annular groove is set on the rotating shaft, and spacer ring lower end is stretched into annular groove.Or it can also set
It is set on spacer ring and annular groove is set, the bulge loop of setting annular protrusion stretches into the annular groove on spacer ring on the rotating shaft
Interior, such effect is so that joint face is a labyrinth curve, to prevent moisture and other impurities infiltration.
Further improve is, sealing ring is set between spacer ring and annular groove；In circle convex platform outboard end
Face sets sealing ring.Sealing ring between spacer ring and annular groove strengthens sealed waterproof effect.
Wherein circle convex platform is arranged on end cap side centre position, and rotation axis is worn out from the hole among annulus, and circle
Step surface is formed on the inside of ring convex platform with end cap end, step surface is withstood on the outside of bearing.Two Double-lip framework oil sealings are oppositely arranged.
Sealing ring between spacer ring and annular groove sets multiple or sealing ring to be set as including a primary seal
Circle sets multiple annular convex platform in the both sides up and down of primary seal circle, and upper annular boss is stretched into the groove on spacer ring, lower section
Annular convex platform is stretched into the groove in annular groove or the lower section of primary seal circle does not set annular convex platform, and only top is set
Annular convex platform.
The band oil enveloping structure wheel hub motor of the utility model using the double sealing structure between rotation axis and end cap, improves
Hub motor driven axis sealing performance effectively prevent infiltration leak, and protection bearing is not easy damage of getting rusty, and extending motor makes
Use the service life.
