Connected by connecting portion between set, outside one end that axle sleeve one end extend out to wheel body, the other end of axle sleeve is located at wheel in vivo, in axle
Set extend out to the external one end of wheel and is provided with the annular stop portion that internal diameter is less than sleeve diameter, in annular stop portion away from the one of axle sleeve
End has spacing plane, is provided with annular spacing groove in the inwall in annular stop portion and the junction of sleeve lining.
In the belt sheave of above-mentioned auto Air Conditioner, the company of described annular stop portion outer wall and axle sleeve outer wall
The place of connecing excessively is connected by arcwall face.
In the belt sheave of above-mentioned auto Air Conditioner, described connecting portion is provided with some even circumferential distributions
The first fabrication hole.
In the belt sheave of above-mentioned auto Air Conditioner, described connecting portion is provided with positioned at adjacent two
The second fabrication hole between one fabrication hole.
In the belt sheave of above-mentioned auto Air Conditioner, it is connected in one end of wheel body outside described connecting portion
Wall, the inner side of connecting portion is connected to one end of axle sleeve.
In the belt sheave of above-mentioned auto Air Conditioner, described wheel body, connecting portion and axle sleeve are connected as a single entity formula
Structure.
Compared with prior art, the advantage of the belt sheave of this auto Air Conditioner is: 1, due to being provided with limit
Bit plane combines the structure of annular spacing groove, it can be avoided that there is the phenomenon of axial displacement during installing, virtually carries
High installation effectiveness.2nd, structure is simple and easily fabricated.
