Abstract
The utility model relates to an integral fan coupler, comprising an outer flange, an inner flange and rubber which are vulcanized integrally. Primary and secondary mouths which are used with each other are arranged at connection positions of the inner flange and the outer flange and are integrally vulcanized via the rubber, and an end cap is disposed outside the outer flange and is connected with the inner flange via a bolt. The inner flange and the outer flange are positioned by the primary and secondary mouths, so that coaxiality of two mounting ends of the fan coupler is improved, and coaxiality of a fan relative to an output shaft of an engine is also improved. During operation, radial movement and axial inward movement of the fan are limited due to the primary and secondary mouths, axial outward movement of the fan is simultaneously limited due to the end cap, accordingly, deflection of the fan in a system operation process is reduced, fatigue damage and breakage risks of the coupler are reduced, simultaneously, system noise is reduced, deflection during operation of the fan is reduced, and invalidation risk is decreased.
Description
Technical field
The utility model relates to the coupling technical field, and a kind of integrated fan coupling of special proposition is used for engine driveshaft and is connected with fan.
Background technique
Present engine-cooling system integral type fan coupling exists two ends assembling and positioning circle concentricity poor, fan beat amount is big, noise is big in the operation process, easily make fan coupling axle journal root produce fatigue damage, finally cause the fracture of coupling axle journal root, fan throws away and damages other parts such as water tank, causes bigger economic loss to client.
Summary of the invention
In order to improve fan coupling reliability, avoid damaging other parts because of product failure, the utility model provides a kind of integrated fan coupling, this structure can improve the precision of product, thereby improve the assembly precision of the relative engine shaft of fan, reduce the beat amount in the fan running process, reduce failure risk.
The technical solution of the utility model is for this reason, a kind of integrated fan coupling, comprise that outward flange, inner flange, rubber are through being sulfided into one, it is characterized in that: the joint of described inner flange and outward flange is provided with the primary and secondary seam that is used, be integral through the vulcanization of rubber again, outward flange is provided with end cap outward, and end cap links together by bolt and inner flange.
Beneficial effect:
The utility model be by outward flange, inner flange, rubber through being sulfided into one, wherein inside and outside flange is located in primary and secondary seam mode, to improve fan coupling two mounting end coaxalitys, the assurance of coaxality has improved the coaxality of the relative engine output shaft of fan.In operation process, because the effect of primary and secondary seam, the radial displacement of fan and axial inside displacement are restricted, because of the effect of end cap, it axially also is restricted to outer displacement, thereby has reduced the beat amount of fan in system's operation process simultaneously, coupling fatigue damage and risk of breakage have been reduced, reduce system noise simultaneously, reduce the beat amount in the fan running process, reduce failure risk.
Description of drawings
Fig. 1 is the utility model integrated fan vibration absorbing coupling structure diagram.
Fig. 2 is that the utility model integrated fan vibration absorbing coupling uses erection drawing.
1 is outward flange, the 2nd among Fig. 1, and frame flange 3 is that rubber 4 is that primary and secondary seam 5 is that end cap 6 is bolts, 7-fan, 8-motor.
Embodiment
The utility model as shown in Figure 1 and Figure 2.
A kind of integrated fan vibration absorbing coupling by outward flange 1, inner flange 2, rubber 3 through being sulfided into one.Outward flange 1 and inner flange 2 joints are provided with primary and secondary seam 4, earlier outward flange 1 and inner flange 2 are assembled together with primary and secondary seam orientation type before the sulfuration, and the rubber 3 that reinjects vulcanizes, and at last 3 bolts 6 of end cap 5 usefulness and outward flange 1 is tightened together.During use, inner flange 2 is connected with motor coupling shaft 8, and outward flange 1 is fixed together with fan 7, when engine shaft 8 rotations, drives inner flange 2, rubber 3, outward flange 1 successively, thereby drives fan 7 rotations.
