The utility model is set to further: the diameter of described axle body, second shaft shoulder, axle journal and axle tail is in gradually little setting, and the diameter of described axle body, first shaft shoulder and spindle nose is in gradually little setting, and described first shaft shoulder is identical with the diameter of second shaft shoulder.
The utility model is set to further: described axle tail is provided with the two plane segments be evenly distributed, and described axle tail is round key type structure along the cross section on direction of axis line.
The utility model is set to further: the both sides of described axle body have been wholely set the first axle body and the second axle body respectively, described the first axle body is located between axle body and first shaft shoulder, described the second axle body is located between axle body and second shaft shoulder, the diameter being less than axis body of described the first axle body and the second axle body, is greater than the diameter of first shaft shoulder.
The utility model is set to further: described the first axle body is identical with the diameter of the second axle body, and the diameter of described the first axle body and the second axle body and the diameter difference of axle body are less than 1mm.
The utility model is set to further: the two ends of described axle body are provided with fillet, and the diameter of described fillet equals the diameter of the first axle body and the second axle body and the diameter difference of axle body.
The utility model is set to further: the end of described axis body is provided with chamfering.
The utility model is set to further: the end face of described spindle nose is provided with Type B center hole.
In sum, the utility model multidiameter shaft is by being divided into planar section and cambered surface section by the bottom surface of keyway, when mounting parts, key is first arranged on planar section, now between part and key, gap is comparatively large, and making to be connected in installation process does not need to use excessive power, when by instrument, key being knocked cambered surface section after installation, make key and part pretension gradually, thus part is fixed, such vibrational power flow advantages of simple, convenient, laborsaving when mounted.
