Abstract
The utility model provides an engine cooling system fan vibration absorption coupling comprising a jacket, a fan flange and rubber that are integrated through vulcanization. The inward turning edge of the jacket is bent and fastened outside the fan flange so that the fan flange and the jacket form a whole. The bottom of the jacket is provided with four assembly holes. The fan flange is provided with four bolts. The assembly holes and the bolts are provided with air outlets at the periphery. The bolts on the fan flange are flange face knurled bolts, and the fan flange is riveted and pressed in. As the inward turning bent structure of the jacket after vulcanization is adopted, certain compression amount of the rubber is generated while turning inwards, namely the performance of the rubber is improved, and the service life of the assembly is prolonged. In the presence of the inward turning edge of the jacket, the failure of the rubber during later stage of use does not cause the fan flange to fly out, hit and break water tanks or other parts. Therefore, the economical loss is reduced.
Description
Technical field
The utility model relates to a kind of engine-cooling system fan vibration absorbing coupling, specifically is to be used for engine driveshaft to be connected with fan.
Technical background
Present fan vibration absorbing coupling adopts is that upper plate, middle plate, lower plate pass through rubber curing forming, the product structure complexity, fatigue behaviour is not enough, ageing of rubber lost efficacy in the long-term operation process of motor, wear and tear between each part of skeleton, until breaking releasing, cause fan to throw away and damage other parts such as water tank, cause bigger economic loss to client.
Summary of the invention
The utility model is in order to improve the rubber fatigue behaviour, increase the mileage in working life of fan vibration absorbing coupling, avoid product to damage other parts because of rubber inefficacy back, a kind of engine-cooling system fan vibration absorbing coupling is provided, this structure is not only optimized rubber performance, and inside and outside metal frame breaks away from other parts of damage after can avoiding product failure.
The technological scheme that the utility model solves is, a kind of engine-cooling system fan vibration absorbing coupling, comprise that overcoat, fan flange, rubber through being sulfided into one, is characterized in that: withhold by the in-flanges bending of overcoat in fan flange outside, make the fan flange become as a whole with overcoat; The bottom of overcoat is provided with pilot hole; The fan flange is provided with bolt.
Improvement to such scheme is: be provided with air outlet hole around pilot hole and bolt.
Improvement to such scheme is: bolt on the described fan flange adopts the flanged surface knurled nut, and presses and be pressed into the fan flange.
Beneficial effect:
The utility model is owing to take to vulcanize turnover kinking structure in the overcoat of back, in-flanges makes rubber produce certain decrement simultaneously, promptly improved rubber performance, prolonged assembly working life, the utility model is because the existence of overcoat in-flanges, can not cause the disengaging of fan flange to fly out, break other component such as water tank, reduce economic loss because of using later stage rubber to lose efficacy.
Description of drawings
Fig. 1 is the utility model fan vibration absorbing coupling structure diagram.
Fig. 2 is that the utility model fan vibration absorbing coupling uses erection drawing.
1 overcoat, 2 fan flanges, 3 rubber, 4 pilot holes, 5 bolts, 6 overcoat in-flangess, 7 fans, 8 motors among the figure.
Embodiment
The utility model as shown in Figure 1 and Figure 2.
The fan vibration absorbing coupling, is carried out the in-flanges bending with the overcoat open-mouth end again and becomes overcoat in-flanges 6 through being sulfided into one by overcoat 1, fan flange 2, rubber 3, makes overcoat 1, fan flange 2,3 one-tenth of rubber as a whole.Fan flange 2 is provided with four bolts 5, and bolt 5 adopts the flanged surface knurled nut, and is pressed into fan flange 2 by pressing.During use, overcoat 1 is connected by pilot hole 4 with motor 8, and fan flange 2 is fixed together by bolt 5 with fan 7, when motor 8 rotations, drives overcoat 1, rubber 3, fan flange 2 successively, thereby drives fan 7 rotations.
