Abstract
The invention discloses a simple fan clutch which comprises a hollow rotating shaft and a fan blade fixing shell. The hollow rotating shaft is sleeved with the fan blade fixing shell. A first bearing corresponding to the fan blade fixing shell is arranged on the hollow rotating shaft. A threaded rod is arranged at the front end of the hollow rotating shaft and sleeved with a bimetallic strip located at the front end of the fan blade fixing shell. The threaded rod is provided with a first nut for fastening the bimetallic strip. By means of the mode, according to the simple fan clutch, when the temperature is lower than 35 DEG C, rotation of the hollow rotating shaft depends on friction of the first bearing and a second bearing to drive the fan blade fixing shell to rotate slowly, when the temperature is higher than 35 DEG C, the bimetallic strip bends and deforms to press the fan blade fixing shell so that the fan blade fixing shell and the hollow rotating shaft can be connected gradually and rigidly, rotating speed of the fan blade fixing shell is increased, and the simple fan clutch is simple in structure, low in production cost, convenient to maintain and good in durability.
Description
Technical field
The present invention relates to clutch field, particularly relate to a kind of Simple fan clutch.
Background technique
Silicon oil filled fan clutch is mainly used on automobile, and in the process of moving, due to the change of environmental conditions and operating conditions, the hot situation of motor, also in change, must regulate the intensity of cooling of motor to automobile at any time.During the broiling summer, motor is at low speed, large working under load, the temperature of cooling liquid is very high, fan should High Rotation Speed to increase cooling air quantity, strengthen the heat dissipation potential of radiator, and in winter of cold, when coolant temperature is lower, or when galloping has powerful head-on wind to blow over radiator, fan works on and just becomes meaningless, not only consumption of engine power in vain, but also produces very large noise, therefore, at any time its intensity of cooling is regulated according to the hot situation of motor and just seemed very important.
In order to realize the Intelligent adjustment with radiator temperature of fan, can between blower pulley and cooling fan device silicon oil filled fan clutch, and the complex structure of silicon oil filled fan clutch, in order to the sealing promoting silicone oil also will add Sealing, cost of production and maintenance cost high.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of Simple fan clutch, promotes serviceability, reduces and produces and maintenance cost.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: provide a kind of Simple fan clutch, comprise: hollow rotating shaft and fan blade stationary housing, described fan blade stationary housing is set on hollow rotating shaft, described hollow rotating shaft is provided with the clutch shaft bearing corresponding with fan blade stationary housing, described hollow rotating shaft front end is provided with threaded stem, described threaded stem is arranged with the bimetallic strip that is positioned at fan blade stationary housing front end, described threaded stem is provided with the first nut of fastening bimetallic strip.
In a preferred embodiment of the present invention, described hollow rotating shaft end is provided with adpting flange, and described adpting flange is provided with mounting hole.
In a preferred embodiment of the present invention, described threaded stem is provided with second bearing corresponding with fan blade stationary housing, described threaded stem is provided with the second nut fixing the second bearing.
In a preferred embodiment of the present invention, described fan blade stationary housing is provided with several flabellum fixed groove.
In a preferred embodiment of the present invention, in described flabellum fixed groove, be provided with tapped hole.
The invention has the beneficial effects as follows: a kind of Simple fan clutch that the present invention points out, when temperature is lower than 35 DEG C, the rotation of hollow rotating shaft relies on the friction of clutch shaft bearing and the second bearing and drives the slow circumvolve of fan blade stationary housing, when temperature is higher than 35 DEG C, and bimetallic strip bending deflection and oppress fan blade stationary housing, make fan blade stationary housing and hollow rotating shaft rigid connection gradually, improve the rotating speed of fan blade stationary housing, structure is simple, low production cost, be convenient to safeguard, serviceability is good.
Accompanying drawing explanation
