Description
Technical field
The utility model is related to radiator fan technical field, specially a kind of radiator fan insulating cover knot with sealing effect
Structure.
Background technology
Radiation fan on vehicle is mainly used for the heat dissipation of automotive interior dynamical element.It is higher dynamic due to being needed when automobilism
Power, therefore, the dynamical element of automotive interior are in high operating status so that it generates higher heat, if do not carried out to it
Heat dissipation, internal element can be influenced by temperature, and lead to the reduction of its service life.
Currently, in the radiator fan of automobile, stator pack is made of PCB components and wire-winding unit, and wire-winding unit is general
It is made of four components：Insulating cover, silicon steel sheet, insulating base and enameled wire.Insulating cover used at present only plays merely support
The effect of coiling coil holder, to other components of radiator fan, not any help, and during the use of radiator fan, ash
It the entrance of dirt and adsorbs and largely accumulates in bearing and the volatilization of lubricating oil loss, lead to bearing and axle center frictional force mistake
Greatly, the failure of radiator fan is eventually led to.
Utility model content
The radiator fan insulating cover structure with sealing effect that the purpose of this utility model is to provide a kind of, it is above-mentioned to solve
The problem of being proposed in background technology.
To achieve the above object, the utility model provides the following technical solutions：A kind of radiator fan with sealing effect is exhausted
The inside bottom of edge lid structure, including outline border, the outline border is fixedly connected with central tube, and the central tube is internally provided with
The inside in axle center, the central tube is fixedly connected with oiliness bearing, and the inner ring of the oiliness bearing is fixedly attached axle center, described
The upper end in axle center is socketed with sealing cover.
Preferably, the sealing cover includes winding slot and insulating cover, and the side of the winding slot is fixedly connected with insulating cover.
Preferably, the upper end of the insulating cover is bent to form protrusion inwardly, and the inner ring of the protrusion bends downward to be formed
Recess, the lower end of the recess is bent to form pressure ring to insulating cover direction of axis line.
Compared with prior art, the utility model has the beneficial effects that：The radiator fan insulating cover knot with sealing effect
Structure keeps insulating cover inconvenient as the function of coiling coil holder, and the upper surface of oiliness bearing is pushed down by pressure ring, can be to oil-containing axis
It holds and plays sealing effect, avoid the occurrence of the feelings that dust enters the inside of oiliness bearing and the volatilization of oiliness bearing internal lubrication oil is lost in
Condition extends the service life of radiator fan, and cost amplification is small.
Description of the drawings
Fig. 1 is the utility model radiator fan finished product sectional view；
Fig. 2 is the structural schematic diagram of the utility model sealing cover；
Fig. 3 is the bending sketch map of the utility model sealing cover.
In figure：1 outline border, 2 central tubes, 3 axle center, 4 oiliness bearings, 5 sealing covers, 6 winding slots, 7 insulating covers, 8 protrusions, 9
Recess, 10 pressure rings.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
In the description of the present invention, it should be understood that term " longitudinal direction ", " transverse direction ", "upper", "lower", " preceding ",
The orientation or positional relationship of the instructions such as " rear ", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" be based on
Orientation or positional relationship shown in the drawings is merely for convenience of description the utility model, does not indicate or imply the indicated dress
It sets or element must have a particular orientation, with specific azimuth configuration and operation, therefore should not be understood as to the utility model
Limitation.
- 3 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of radiator fan insulating cover with sealing effect
The inside bottom of structure, including outline border 1, outline border 1 is fixedly connected with central tube 2, and central tube 2 is internally provided with axle center 3, in
The inside of heart pipeline 2 is fixedly connected with oiliness bearing 4, and the inner ring of oiliness bearing 4 is fixedly attached axle center 3, the upper end socket in axle center 3
It includes winding slot 6 and insulating cover 7 to have sealing cover 5, sealing cover 5, and the side of winding slot 6 is fixedly connected with insulating cover 7, keeps insulating cover
The upper end of the 7 function inconvenience as coiling coil holder, insulating cover 7 is bent to form protrusion 8 inwardly, and the inner ring of protrusion 8 is bent downward
Recess 9 is formed, 9 lower end of being recessed is bent to form pressure ring 10 to 7 direction of axis line of insulating cover, and the bending of 7 upper end of insulating cover is all
90 degree of bendings, form protrusion 8, recess 9 and pressure ring 10, and the inner ring diameter of pressure ring 10 is slightly larger than the diameter in axle center 3, avoids the occurrence of
There is a situation where rubbing between pressure ring 10 and axle center 3, the pressure ring 10 that insulating cover 7 is bent out pushes down the upper surface of oiliness bearing 4, right
Oiliness bearing 4 plays the effect of sealing, is equivalent to and additionally increases a sealing cover to oiliness bearing 4, can be greatly decreased
The entrance of dust, entering after avoiding dust from accumulating inside oiliness bearing 4 leads to stuck situation, meanwhile, pressure ring 10 is to oil-containing axis
The effect of a sealing can be played by holding the lubricating oil in 4 also, and equivalent to increase an anti-oil cap, lubricating oil is not volatile, makes
Longer with the time, lubricant effect is more preferable, is less prone to all kinds of performance issues caused by the reduction of lubricating oil.
The utility model is in the specific implementation：It keeps insulating cover 7 inconvenient as the function of coiling coil holder, passes through what is bent out
The upper end of central tube 2 is blocked in raised 8 lower surfaces, then avoids flabellum lug boss position by recess 9, is then pushed down and is contained by pressure ring 10
The upper surface of oil bearing 4 can play sealing effect to oiliness bearing 4, avoid the occurrence of dust enter oiliness bearing 4 inside and
The case where volatilization of 4 internal lubrication oil of oiliness bearing is lost in, extends the service life of radiator fan.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
