Alternator having vacuum pump capable of improving cooling characteristic |
摘要 |
In an alternator having a vacuum pump capable of improving a cooling characteristic, and having a rotary shaft supported by bearings installed in a rear bracket of the alternator, a housing of the vacuum pump has vanes and a rotation rotor is installed on the rotary shaft. A pump bracket is assembled to a lower portion of the housing and includes a packing inserted in an outer circumferential portion of a center shaft hole of the pump bracket for implementing a sealing operation in surface-contact with the rear bracket. A certain space is formed between the packing and the shaft hole for preventing a heat transfer, and a heat radiating unit is installed in a lower surface of the pump bracket.
