In this way, simple and easy fan clutch, when the temperature is less than 35 DEG C, the rotatory slow rotation that relies on the friction of first bearing and second bearing and drive the fixed casing of fan blade of hollow rotating shaft, when the temperature is higher than 35 DEG C, bimetallic strip bending deformation and oppress the fan blade and fix the casing for fixed casing of fan blade and hollow rotating shaft be rigidly connected gradually, has promoted the rotational speed of the fixed casing of fan blade, simple structure, and low in production cost is honest and clean, is convenient for safeguard that the durability is good.
Description
Technical field
This utility model relates to clutch field, particularly relates to a kind of Simple fan clutch.
Background technology
Silicon oil filled fan clutch is mainly used on automobile, and in the process of moving, due to environmental condition and the change of operating condition, the thermal conditions of electromotor is also changing automobile, it is necessary to regulate the intensity of cooling of electromotor at any time.During the broiling summer, electromotor is at low speed, big working under load, the temperature of coolant is the highest, fan should high speed rotating to increase cooling air quantity, strengthen the heat-sinking capability of radiator, and in cold winter, when coolant temperature is relatively low, or when galloping has powerful head-on wind to blow over radiator, fan works on and just becomes meaningless, consumption of engine power the most in vain, but also produces the biggest noise, therefore, at any time its intensity of cooling is regulated according to the thermal conditions of electromotor and just seemed particularly significant.
In order to realize the Intelligent adjustment with radiator temperature of fan, can blower pulley and cooling fan between device silicon oil filled fan clutch, and the structure of silicon oil filled fan clutch is complicated, in order to promote the sealing of silicone oil sealing member to be added, production cost and maintenance cost are high.
Utility model content
This utility model, mainly solving the technical problems that provide a kind of Simple fan clutch, promotes ruggedness, reduces and produce and maintenance cost.
For solving above-mentioned technical problem, the technical scheme that this utility model uses is: provide a kind of Simple fan clutch, including: hollow rotating shaft and fan blade fix housing, described fan blade is fixed housing and is set on hollow rotating shaft, it is provided with on described hollow rotating shaft and fixes the clutch shaft bearing that housing is corresponding with fan blade, described hollow rotating shaft front end is provided with threaded rod, it is arranged with one on described threaded rod to be positioned at fan blade and fix the bimetal leaf of housing forward end, described threaded rod is provided with the first nut of fastening bimetal leaf.
In one preferred embodiment of this utility model, described hollow rotating shaft end is provided with adpting flange, and described adpting flange is provided with installing hole.
In one preferred embodiment of this utility model, described threaded rod is provided with and fixes the second bearing that housing is corresponding with fan blade, described threaded rod is provided with the second nut fixing the second bearing.
In one preferred embodiment of this utility model, described fan blade is fixed and is provided with several flabellum on housing and fixes groove.
In one preferred embodiment of this utility model, described flabellum is provided with screwed hole in fixing groove.
The beneficial effects of the utility model are: a kind of Simple fan clutch that this utility model is pointed out, when temperature is less than 35 DEG C, rotating of hollow rotating shaft relies on clutch shaft bearing and the friction of the second bearing to drive fan blade to fix the slow rotation of housing, when temperature is higher than 35 DEG C, bimetal leaf flexural deformation and oppress fan blade and fix housing, fan blade is made to fix housing and hollow rotating shaft gradually rigid connection, improve fan blade and fix the rotating speed of housing, simple in construction, low production cost, being easy to safeguard, ruggedness is good.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, in describing embodiment below, the required accompanying drawing used is briefly described, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of this utility model a kind of Simple fan clutch one preferred embodiment.
Detailed description of the invention
Technical scheme in this utility model embodiment will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Referring to Fig. 1, this utility model embodiment includes:
A kind of Simple fan clutch, including: hollow rotating shaft 1 and fan blade fix housing 2, described fan blade is fixed housing 2 and is set on hollow rotating shaft 1, it is provided with on described hollow rotating shaft 1 and fixes clutch shaft bearing corresponding to housing 2 15 with fan blade, described hollow rotating shaft 1 front end is provided with threaded rod 11, it is provided with on described threaded rod 11 and fixes the second bearing 13 that housing 2 is corresponding with fan blade, described threaded rod 11 is provided with the second nut 14 fixing the second bearing 13, it is to avoid getting loose of the second bearing 13.When temperature is less than 35 DEG C, rotating of hollow rotating shaft 1 relies on clutch shaft bearing 15 and the friction of the second bearing 13 to drive fan blade to fix the slow rotation of housing 2, and energy consumption is little, reduces the load of electromotor.
It is arranged with one on described threaded rod 11 to be positioned at fan blade and fix the bimetal leaf 3 of housing 2 front end, described threaded rod 11 is provided with the first nut 4 of fastening bimetal leaf 3.When temperature is higher than 35 DEG C, bimetal leaf 3 is gradually curved deformation along with the rising of temperature, thus oppresses fan blade and fix housing 2, fan blade is made to fix housing 2 and hollow rotating shaft 1 gradually rigid connection, improve fan blade and fix the rotating speed of housing 2, dispel the heat, reduce the temperature of electromotor.
Described hollow rotating shaft 1 end is provided with adpting flange 12, and described adpting flange 12 is provided with installing hole.Utilizing adpting flange 12, hollow rotating shaft 1 is connected with the drive shaft of fan so that hollow rotating shaft 1 high speed rotating, hollow rotating shaft 1 is hollow, and lightweight, energy consumption is little.
Described fan blade is fixed and is provided with several flabellum on housing 2 and fixes groove 21, and described flabellum is provided with screwed hole 22 in fixing groove 21.Utilize bolt that several flabellums are fixed on fan blade and fix housing 2, fix the rotation of housing 2 along with fan blade and produce wind-force and dispel the heat.
In sum, a kind of Simple fan clutch that this utility model is pointed out, overall design is ingenious, Stability Analysis of Structures, low production cost, and is easy to safeguard, it is not necessary to electronic equipment and silicone oil, ruggedness is good, and service life is long.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, the most in like manner it is included in scope of patent protection of the present utility model.
