Abstract
The utility model discloses a kind of wheel hub motor, comprise motor, wheel hub and end cap, wheel hub connects the rotating shaft of motor, wheel hub both sides are fixed with end cap, rotating shaft two ends are provided with bearing, bearing is fixed on end cap, rotating shaft two ends are provided with scrobicular ring, and end caps corresponding to scrobicular ring top is provided with bulge loop, is coated with sealing ring on bulge loop, sealing ring comprises sticking part, sticking part extends to form sharp lip downwards, and sticking part both sides stretch out and form the sealing lip upwarping, sharp lip and scrobicular ring matched in clearance, sealing lip and scrobicular ring interference fit, fill grease between sealing lip and scrobicular ring.Wheel hub motor good sealing effect of the present utility model, can avoid motor to break down, and extends motor useful life.
Description
Technical field
The utility model relates to machine field, is specifically related to a kind of wheel hub motor.
Background technology
At present, the permanent magnet DC motor using in electric motor car adopts hub-type design more, generally feedback is easily entered dust, water droplet and foreign material, and then cause bearing damage, the magnet steel a series of faults such as inefficacy, Hall fault, defective insulation of getting rusty, as long as there is above arbitrary fault, motor just cannot normally be worked.This kind of situation major part is because sealing ring sealing effectiveness is not good, produces gap and cause between rotating shaft and sealing ring.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of wheel hub motor of good sealing effect is provided.
For achieving the above object, the technical solution of the utility model is: a kind of wheel hub motor, comprise motor, wheel hub and end cap, described wheel hub connects the rotating shaft of motor, wheel hub both sides are fixed with end cap, described rotating shaft two ends are provided with bearing, described bearing is fixed on end cap, described rotating shaft two ends are provided with scrobicular ring, end caps corresponding to described scrobicular ring top is provided with bulge loop, on described bulge loop, be coated with sealing ring, described sealing ring comprises sticking part, described sticking part extends to form sharp lip downwards, sticking part both sides stretch out and form the sealing lip upwarping, described sharp lip and scrobicular ring matched in clearance, described sealing lip and scrobicular ring interference fit, between sealing lip and scrobicular ring, fill grease.
The cross section of described scrobicular ring is sharp-tooth shaped, and the cross section of described bulge loop is sharp-tooth shaped.
The one-sided scrobicular ring quantity of described rotating shaft is two.
Described sharp lip and scrobicular ring lowermost end matched in clearance.
Described sealing lip and scrobicular ring two side interference fit.
The beneficial effects of the utility model: good sealing effect, can avoid motor to break down, extend motor useful life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged drawing at A place in Fig. 1.
In figure: motor 1, rotating shaft 2, wheel hub 3, end cap 4, bearing 5, scrobicular ring 6, bulge loop 7, sticking part 8, sharp lip 9, sealing lip 10, grease 11.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
As Fig. 1, shown in Fig. 2, a kind of wheel hub motor, comprise motor 1, wheel hub 3 and end cap 4, described wheel hub 3 connects the rotating shaft 2 of motor 1, wheel hub 3 both sides are fixed with end cap 4, described rotating shaft 2 two ends are provided with bearing 5, described bearing 5 is fixed on end cap 4, described rotating shaft 2 two ends are provided with scrobicular ring 6, end cap 4 places of described scrobicular ring 6 top correspondences are provided with bulge loop 7, on described bulge loop 7, be coated with sealing ring, described sealing ring comprises sticking part 8, described sticking part 8 extends to form sharp lip 9 downwards, sticking part 8 both sides stretch out and form the sealing lip 10 upwarping, described sharp lip 9 and scrobicular ring 6 matched in clearance, described sealing lip 10 and scrobicular ring 6 interference fit, between sealing lip 10 and scrobicular ring 6, fill grease 11.
The cross section of described scrobicular ring 6 is sharp-tooth shaped, and the cross section of described bulge loop 7 is sharp-tooth shaped.
One-sided scrobicular ring 6 quantity of described rotating shaft 2 are two, dual-seal better effects if.
Described sharp lip 9 and scrobicular ring 6 lowermost end matched in clearance, matched in clearance makes not friction between sharp lip 9 and scrobicular ring 6, has increased the difficulty that dust, water droplet and foreign material enter motor 1 inside simultaneously.
Described sealing lip 10 and scrobicular ring 6 two side interference fit, can blocks dust, water droplet and foreign material enter motor 1 inside, sealing lip 10 is for conventional sealing ring, less with the contact-making surface of rotating shaft 2, rub little, can reduce the resistance of motor 1 operation, sealing lip 10 ends upwarp simultaneously, even if sealing lip 10 in use has wearing and tearing, its end upwarping can move down under Action of Gravity Field, still can keep and scrobicular ring 6 sidewall interference fit, simultaneously can be so that inner grease 11 can be not excessive, grease 11 can further stop dust, entering of water droplet and foreign material.
