Description
Technical field
The utility model relates to technical field of automobile parts, relates in particular to a kind of transportation diesel fan bracket assembly.
Background technique
Transportation diesel generally adopts cooling fan that diesel engine is dispelled the heat; Along with the diesel engine strengthening degree improves constantly; The cooling fan that requires diesel engine to be equipped with must possess enough cooling capacities, and especially on the heavy-duty car that engineering machinery such as bulldozer, excavator are used, its operating environment is abominable; Yet fan through Bearing Installation on fan bracket; Under bad working environment,, thereby influence the stability of fan running and the working life of bearing owing to dust is easy between the ball of bearing face entering bearing, cause bearing to be damaged.
Summary of the invention
The utility model technical problem to be solved is: the deficiency to existing technology exists provides a kind of good dustproof effect, the diesel engine fan bracket assembly of long service life.
For solving the problems of the technologies described above; The technological scheme of the utility model is: diesel engine fan bracket assembly; Comprise the fan bracket body that is installed on the said diesel engine housing, the two ends of said fan bracket body are provided with the clutch shaft bearing and second bearing that is oppositely arranged, and said clutch shaft bearing and the constraint of second bearing are equipped with the main shaft that is used to install fan; The end that said fan bracket body is positioned at said clutch shaft bearing is provided with belt pulley; Said belt pulley is fixedly installed on the said main shaft, is provided with first sealing cover between said belt pulley and the clutch shaft bearing, is provided with second sealing cover between the said fan bracket body and second bearing.
As a kind of improvement, on said first sealing cover suit and the said main shaft, and the outer rim of said first sealing cover relies on the said fan bracket body.
As further improvement, said second sealing cover is installed on the said bracket body and is positioned at the terminal outside of said main shaft.
Owing to adopted technique scheme; The beneficial effect of the utility model is: owing to be provided with first sealing cover between belt pulley and the clutch shaft bearing; Be provided with second sealing cover between the fan bracket body and second bearing, its mechanism is simple, makes the inner chamber of fan bracket body be in the complete closed state; Both avoided the leakage of lubricant grease in the fan bracket chamber body; Avoided impurity such as dust dirt to get between the ball of bearing again, guaranteed the stability of fan running, prolonged the working life of bearing from bearing face; Simultaneously, first sealing cover, second sealing cover are compared with traditional oil sealing, and simple in structure, wear-resisting property is good, long service life.
Description of drawings
Accompanying drawing is the utility model embodiment's a structural representation;
Among the figure, 1. fan bracket body, 2. main shaft, 3. belt pulley, 4. clutch shaft bearing, 5. second bearing, 6. woodruff key, 7. first sealing cover, 8. second sealing cover, 9. gland, 10. straight-through type forced filling oil cup.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Shown in accompanying drawing, a kind of diesel engine fan bracket assembly comprises the fan bracket body 1 that is installed on the said diesel engine housing; The two ends of said fan bracket body 1 are provided with the clutch shaft bearing 4 and second bearing 5 that is oppositely arranged, and said clutch shaft bearing 4 and 5 constraints of second bearing are equipped with the main shaft 2 that is used to install fan, usually; The clutch shaft bearing 4 and second bearing 5 are set on the main shaft 2, and the clutch shaft bearing 4 and second bearing 5 all are installed in the inner chamber of fan bracket body 1 then, and the end of main shaft 2 is provided with gland 9; Gland 9 relies on the end face of second bearing 5; The end that said fan bracket body 1 is positioned at said clutch shaft bearing 4 is provided with belt pulley 3, and said belt pulley 3 is fixedly installed on the said main shaft 2 through woodruff key 6, is provided with first sealing cover 7 between said belt pulley 3 and the clutch shaft bearing 4; Be provided with second sealing cover 8 between the said fan bracket body 1 and second bearing 5; On said first sealing cover, 7 suits and the said main shaft 2, and the outer rim of said first sealing cover 7 relies on the said fan bracket body 1, that is to say; First sealing cover 7 is arranged between the end face of belt pulley 3 and clutch shaft bearing 4; To prevent that dust from getting into from the end face of clutch shaft bearing 4, said second sealing cover 8 is installed on the said bracket body and is positioned at the outside of said main shaft 2 ends, gets into from the end face of second bearing 5 to prevent dust.
During work, belt pulley 3 drives the magnetic clutch that is fixed on the main shaft 2 and rotates through belt drives, and magnetic clutch can reach the purpose that diesel engine is dispelled the heat according to the rotating speed of the temperature regulation fan of cooling water.Straight-through type forced filling oil cup 10 is installed on fan bracket body 1; Straight-through type forced filling oil cup 10 is communicated with the inner chamber of fan bracket body 1; Making main shaft 2 runnings steadily, be provided with first sealing cover 7 between belt pulley 3 and the clutch shaft bearing 4 toward the inner chamber filling lubricant grease of fan bracket body 1; Be provided with second sealing cover 8 between the fan bracket body 1 and second bearing 5; Make the inner chamber of fan bracket body 1 be in the complete closed state, get into from the end face of the clutch shaft bearing 4 and second bearing 5, prolonged the working life of the clutch shaft bearing 4 and second bearing 5 effectively to prevent dust.
The utility model is not limited to above-mentioned concrete mode of execution, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection domain of the utility model.
