Abstract
Provided is a noise reduction end cap for an AC generator used in vehicles. The steam vents formed between radiating ribs of the end cap present a trumpet shape, without closed angles. Therefore, when the wind passes through the surface of the radiating ribs, the wind can smoothly pass through, thereby causing no noise.
Description
Technical field
The utility model is a kind of noise reduction end cap of vehicle-mounted dlternator.
Technical background
The stator assembling of generator is installed on the protecgulum during generator assembling, and the bonnet of generator is installed in the stator fit on.When generator was worked, the generator amature rotation drove fan rotation on the rotor.The wind that fan is discharged is discharged generator through the louvre of first rear end cap.There is wedge angle because of generator end covers the radiating ribs cross section that facings the wind, produces noise during through radiating ribs surface wedge angle at wind.
Summary of the invention
The purpose of this utility model is, solves above-mentioned existing existing problem, and a kind of noise reduction end cap of the vehicle-mounted dlternator that abates the noise is provided.
The utility model is achieved in that the steam vent that is constituted between the radiating ribs of end cap is horn-like, does not exist wedge angle.
Advantage of the present utility model is, because the steam vent that is constituted between the radiating ribs of end cap is horn-like, does not have wedge angle; Through the radiating ribs surface, by steam vent, can not produce noise at wind smoothly.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a left view;
Fig. 3 is the B-B cutaway view of Fig. 1.
Embodiment
Describe in detail below in conjunction with accompanying drawing: as shown in the figure, the steam vent 1a that is constituted between the radiating ribs of end cap 1 is horn-like, does not have wedge angle.
Claims (1)
1. the noise reduction end cap of a vehicle-mounted dlternator that abates the noise is characterized in that, the steam vent that is constituted between the radiating ribs of end cap is horn-like, does not have wedge angle.
