Technical field
The utility model relates to a kind of fan bracket for motor, belongs to technical field of automobile engine.
Background technique
At present general high-power diesel engine adopts the Wind Volume fan, and the axial reaction force that big fan produces is very large, and the engine blower carriage bears excessive axial force, can cause fan bracket axle axial float, and then causes damage of bearings and belt pulley to come off.
The model utility content
The utility model is for solving the problems of the technologies described above, and a kind of reliable in structure, engine blower carriage that the fault point is few are provided.
To achieve these goals, the utility model adopts following technological scheme.
A kind of engine blower carriage comprises belt pulley, rotating shaft, oil sealing spacer, outside framework oil seal, spacer, the first rolling bearing, the second rolling bearing, fan bracket housing, circlip for hole, straight-through type forced filling oil cup; The fan bracket enclosure interior is fixed in described rotating shaft, is provided with successively oil sealing spacer, the first rolling bearing, spacer, circlip for hole and the second rolling bearing in the rotating shaft, is provided with outside framework oil seal between described oil sealing spacer and the rotating shaft; Outside framework oil seal, the first rolling bearing, circlip for hole and the second rolling bearing are interference fitted on the inwall of fan bracket housing; The fan bracket housing is stretched out in rotating shaft near oil sealing spacer one end, and is fixed with belt pulley; Described fan bracket housing is provided with the straight-through type forced filling oil cup.
As further improvement of the utility model, described engine blower carriage also comprises dust cover, and described dust cover is arranged in the rotating shaft away from oil sealing spacer one end.
Described away from also being provided with compact heap in the rotating shaft of oil sealing spacer one end; Compact heap can be fixed by the first hexagon head bolt.
As further improvement of the utility model, belt pulley is fixed in the rotating shaft by the second hexagon head bolt, the direction that described the second hexagon head bolt screws in rotating shaft is opposite with the sense of rotation of belt pulley, so only can make rotating shaft more and more tighter, has guaranteed fixing reliability.
The utility model beneficial effect: reliable in structure, fault point are few, have guaranteed the motor reliability of operation.
