Abstract
The present invention relates to a kind of motor height to protect fan blade, including fan blade ontology, fan blade axle center, and the intracardiac circle of blade shaft is equipped with annular knurl；If the fan blade ontology is respectively arranged with the fan-shaped snubber elastomeric slot of a hollow out being evenly distributed in fan blade axle center positive and negative；Two circle dust and water protection cage rings are equipped at the fan blade ontology inner blade central diameter.Present invention positive and negative at fan blade axle center increase eight pieces of fan-shaped snubber elastomeric slots, avoid the problems such as being broken in the past because of fan blade axle center caused by interference fit；It is designed using at blade shaft cooperation using annular knurl, can increase the enclasping force of cooperation, fan blade falls off caused by avoiding because of rotor temperature rise, instead of fastened by screw fan blade is used in the past, more saves raw material.In being equipped at fan blade inner blade central diameter, outer two circles thrower can effectively be isolated rainwater dust and be entered inside motor by end cap oil sealing position.
Description
Technical field
The present invention relates to a kind of motor blower fans, protect fan blade more particularly to a kind of motor height.
Background technique
Electric motor fan blade is motor radiating component, and motor blower fan used at present mostly uses screw to lock or be interference fitted admittedly
It is assembled due to rotor tail end, fan blade in use, since rotor temperature rise etc. influences, easily takes off fan blade fever
Phenomenon is fallen, and previous fan blade can only play heat spreading function, have no the design for motor protection.
Summary of the invention
For above-mentioned defect existing in the prior art, can improve technical problem to be solved by the invention is to provide a kind of
The motor height of fan blade enclasping force and increase with protective performance protects fan blade.
The purpose of the present invention is achieved through the following technical solutions：
A kind of motor height protection fan blade, including fan blade ontology, fan blade axle center, the intracardiac circle of blade shaft are equipped with annular knurl；The wind
If leaf ontology is respectively arranged with the fan-shaped snubber elastomeric slot of a hollow out being evenly distributed in fan blade axle center positive and negative；The wind
Two circle dust and water protection cage rings are equipped at leaf ontology inner blade central diameter.
Further, the fan blade ontology is respectively arranged with the fan-shaped snubber elastomeric of eight pieces of hollow outs in fan blade axle center positive and negative
Slot.
Further, the motor height protection fan blade, which is fitted close by the annular knurl on the intracardiac circle of blade shaft with machine shaft, connects
It connects.
Further, the fan blade ontology is equipped with removal hole.
For the prior art, the beneficial effects of the present invention are：
1. present invention reverse side positive at fan blade axle center increases 8 pieces of fan-shaped snubber elastomeric slots, avoid in the past because interference fit fills
The problems such as with the fracture of caused fan blade axle center.
2. the present invention can increase the enclasping force of cooperation using designing at blade shaft cooperation using annular knurl, avoid turning because of motor
Fan blade caused by sub- temperature rise falls off, and instead of fastened by screw fan blade is used in the past, more saves raw material.
3. in the present invention is equipped at fan blade inner blade central diameter, rainwater dust can be effectively isolated in outer two circles thrower
Entered inside motor by end cap oil sealing position.
4. general rainwater and dust has effectively been isolated due to being provided with two circle throwers at fan blade in the present invention
Invasion, motor degree of protection has reached IP55, at end cap oil sealing position oil sealing can not be installed, while saving raw material
It also improves indirectly by oil sealing friction bring machinery consumption, to improve electric efficiency.
Detailed description of the invention
Fig. 1 is the structural front view of motor height protection fan blade of the invention；
Fig. 2 is the structure rearview of motor height protection fan blade of the invention；
Fig. 3 is the cross-sectional view that motor height protection fan blade and end cap of the invention are coupled；
In figure：1, fan blade ontology, 2, the fan-shaped snubber elastomeric slot of hollow out, 3, blade, 4, annular knurl, 5, removal hole, 6, outer water dumping
Circle, 7, interior thrower, 8, motor rear cover.
Specific embodiment
The content of present invention is described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1 to Figure 3, motor height of the invention protects fan blade, including fan blade ontology 1, blade 3, fan blade axle center.Wind
The intracardiac circle of rachis is equipped with annular knurl；Fan blade ontology 1 is respectively arranged with the hollow out that eight are evenly distributed in fan blade axle center positive and negative
Fan-shaped snubber elastomeric slot 2；It is equipped with two circle dust and water protection cage rings at 1 inner blade central diameter of fan blade ontology, is water dumping in a circle
Circle 7, another circle are outer thrower 6.Motor height protection fan blade is closely matched by the annular knurl on the intracardiac circle of blade shaft with machine shaft
Close connection.Fan blade ontology 1 is equipped with removal hole 5.
Working principle of the present invention is as follows：
It by horizontal aligument rotor tail end at the annular knurl 4 in fan blade axle center, is knocked in rubber hammer, at this time the fan-shaped buffering elastic of hollow out
Property slot 2 due to be pressurized, can expand outwardly, fan blade axle center would not cause to be broken, at the annular knurl 4 in fan blade axle center hold tightly motor turn
Sub- axial plane makes blade body 1 be not easy heated to cause to fall off.When motor operation, rainwater is sprayed into from outside motor fan housing hole, water droplet stream
When entering 8 face gradient of motor rear cover, when into outer thrower 6, outer thrower 6, which can take advantage of a situation, throws away rainwater, if any getting rid of in leaking into
Hydrosphere 7, interior thrower 7 can get rid of rainwater to outer ring, play two layers of protection effect.It is dust-proof similarly.
