Retaining ring and anticreep part, bearing are avoided that and exist in outer rotor blower fan compared with being provided with adjusting washer between rotor fan blade component
During high-speed cruising, the friction that contacts with each other can be generated between shaft end ring and anticreep part, reduced shaft end ring and generated pine
It is dynamic, effectively avoid falling off between rotor fan blade component and stator module；And bearing can be effectively avoided directly to connect with adjusting washer
Touching, is additionally provided with the taper washer that can be buffered, makes axis in the case where running at high speed between axis and adjusting washer, reduce bearing
Dry friction with adjusting washer and make the dry friction between bearing inner race and axis, and then effectively reduces bearing inner race and bearing outer ring
It mutually slips, to reduce falling off for outer rotor blower fan fan blade.Effectively raise the quality and service life of product.
Scheme as a preference of the above scheme has been sequentially arranged taper from bearing to rotor fan blade component on central axis
Washer and adjusting washer.Taper washer is avoided that between adjusting washer and bearing and directly contacts, and effectively reduces bearing and adjusting pad
Dry friction between circle, and buffering can be played the role of.
Scheme as a preference of the above scheme, taper washer include two pieces of taper gaskets, and two pieces of taper gaskets are opposite
Arrangement.Two pieces of taper gaskets are positioned opposite, can play the role of buffering, and can be reduced taper gasket and bearing, taper gasket with
Contact area between rotor fan blade component, and then reduce mutual friction.
Scheme as a preference of the above scheme, taper gasket are made of gasket ring and presser feet, have between gasket ring and presser feet
One cone angle.There is a cone angle between gasket ring and presser feet, cone angle plays the role of buffering.
Scheme as a preference of the above scheme, the cone angle between gasket ring and presser feet are 10 ~ 20 degree.When gasket ring and presser feet
Between cone angle less than 10 degree when, effect is unobvious；When the cone angle between gasket ring and presser feet is greater than 20 degree, function and effect are poor.
Scheme as a preference of the above scheme, bearing include bearing inner race, bearing outer ring and be located at bearing inner race and
Ball between bearing outer ring is interference fit between bearing inner race and central axis.It is interference between bearing inner race and central axis
Cooperation guarantees effectively connection and transmission.
Scheme as a preference of the above scheme is interference fit between bearing outer ring and rotor fan blade component.Bearing
It is interference fit between outer ring and rotor fan blade component, guarantees effectively connection and transmission.
Scheme as a preference of the above scheme, bearing are deep groove ball bearing or angular contact ball bearing.Deep groove ball bearing
Or angular contact ball bearing, stable structure, be able to satisfy requirement in the case of cost is relatively low.
The beneficial effects of the utility model are:
1. the disconnecting prevention structure that the utility model uses can effectively reduce falling off for outer rotor blower fan fan blade, product is improved
Quality and service life；
2. the taper washer of the utility model is arranged in the form of the opposite fitting of two pieces of taper gaskets, reduction can be reached and rubbed
The effect wiped and buffered, and then reduce falling off for outer rotor blower fan fan blade；
