本発明は車両用充電発電機に係り、特に、充電
発電機の回転子に冷却フアンを固定する構造に関
する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a charging generator for a vehicle, and more particularly to a structure for fixing a cooling fan to a rotor of a charging generator.
一般に、車両用充電発電機は小型化及び高出力

た。 Generally, there is a strong need for vehicle charging generators to be smaller in size and have higher output, and in response to these needs, a built-in cooling fan is installed to improve cooling efficiency. Tokukai Akira
As is known from Publication No. 56-98357, the cooling fan of the conventional charging generator for this type of vehicle that uses claw-shaped magnetic poles as a rotating field type rotor is either screwed to the side wall of the claw-shaped magnetic poles, or Alternatively, a structure is adopted in which it is fixed to the rotor by a method such as being press-fitted onto the shaft of the rotor. However, the above-mentioned screw fixing requires man-hours and is expensive, and the method of press-fitting the shaft onto the shaft has drawbacks such as a lack of fixing force and the cooling fan spinning around during high-speed rotation, and both methods have poor productivity. There were drawbacks such as lack of reliability. Therefore, in recent years, a method has been adopted in which the cooling fan is directly fixed to the magnetic pole by welding, but in this method, the welding work reduces the efficiency of the assembly work, and the material of the cooling fan is limited. This method has the disadvantage that it is difficult to confirm the adhesion force afterward, so it cannot necessarily be said to be a highly reliable fixing method.
本発明の目的は、上記の欠点を解消し、爪型磁
極の端面に固定される冷却フアンの固着力の信頼

電機を提供することにある。 It is an object of the present invention to eliminate the above-mentioned drawbacks, to ensure the reliability of the fixing force of the cooling fan fixed to the end face of the claw-shaped magnetic pole, and to reduce the man-hours and costs in fixing the cooling fan. The purpose of the present invention is to provide a charging generator for vehicles.

高さの低い別の突部を形成することによつて達成
される。 The above-mentioned object of the present invention is to form a stepped recess on the outer periphery of the end face of the claw-shaped magnetic pole, and to sandwich a cooling fan between the stepped recess and a support member placed in contact with the end face of the claw-shaped magnetic pole. Moreover, on the end surface of the support member on the claw-shaped magnetic pole side, a protrusion is formed on the outer circumferential side facing the stepped recess of the claw-shaped magnetic pole, and a protrusion is formed on the inner circumferential side of the protrusion, which is lower in height than the protrusion on the outer circumferential side. This is achieved by forming a protrusion.

ることができる。 According to the present invention configured in this manner, the cooling fan can be fixed to the end surface of the claw-shaped magnetic pole in a state of being curved with respect to a plane perpendicular to the rotation axis by elastic deformation. The fixing force acts on two places, the radially inner side and the radially outer side, and a strong fixing force can be obtained with an extremely simple operation.

The figure is a cross-sectional view showing only the above-mentioned support member 7. On the end face of the support member 7 on the claw-shaped magnetic pole side, a protrusion 71 is provided on the outer circumferential side facing the stepped recess 5 on the claw-shaped magnetic pole end face.

回転軸１に強力に固着されている。 FIG. 4 shows the process of fixing the cooling fan 6 to the end face of the claw-shaped magnetic pole 2. After the yoke 3 and the claw-shaped magnetic pole 2 are firmly fixed to the rotating shaft 1, the cooling fan 6 is loosely fitted to the rotating shaft 1 and is placed in close contact with the end surface protrusion of the claw-shaped magnetic pole 2. Next, the support member 7 is press-fitted onto the rotating shaft 1 so that the protrusions 71 and 72 face the cooling fan 6, and the protrusions 72 press against the side surface of the cooling fan 6. However, immediately before pressing, there is a gap t 2 between the support member 7 and the cooling fan 6, and there is also a gap t 1 between the cooling fan 6 and the end face of the claw-shaped magnetic pole 2.
From this state, when the support member 7 is moved in the axial direction so that the distance t 2 between the cooling fan 6 and the support member 77 becomes zero, the cooling fan is elastically deformed, and the cooling fan 6 is moved between the claw-shaped magnetic poles 2. It is pressed against the end face in a curved state. At this time, the support member 7 is made of a metal material having approximately the same strength as the cooling fan 6,
It is strongly fixed to the rotating shaft 1.

持される。 In this embodiment, since t 2 >t 1 , the support member 7 itself also elastically deforms and curves in the attached state shown in FIG. Thus, in this embodiment, not only is the cooling fan sandwiched between the protrusion 72 of the support member 7 and the inner protrusion of the claw-shaped magnetic pole 2, but also the cooling fan is held between the protrusion 71 and the cooling fan by its own elastic force. The cooling fan 6 is firmly fixed and held between the cooling fan 6 and the outer peripheral edge of the claw-shaped magnetic pole 2 by the holding force based on the surface pressure between the cooling fan 6 and the outer peripheral edge of the claw-shaped magnetic pole 2.

A holding force can be obtained due to the surface pressure between the cooling fan 6 and the cooling fan 6, and the effects of the present invention can also be obtained with this.
