And expansion 4, the major axis 1, camshaft 2 and 3 head and the tail of short axle are sequentially connected integral, the dead in line of three.The major axis 1
End can be inserted into the centre bore of the rotor 11 of compressor, be connected together with rotor 8 using hot cover process.The camshaft 2
Outside is cased with cam 5, and is secured to be connected as a body, and cam 5 is cylindrical structure, the axis of cam 5 and putting down for camshaft 2
OK, cam 5 is located at the inside of the cylinder body 12 of compressor.Inside the undersetting 13 of the insertion compressor of the short axle 3, can be relative under
Bearing 13 is rotated.
The inside of the major axis 1 has the circular hole 6 being coaxial therewith, and major axis 1 is provided with expansion away from the inside of one end of short axle 3
Hole 7, the axis in the expansion hole 7 and the dead in line of major axis 1, and be connected with circular hole 6 and communicate.The inside of the major axis 1 also sets
The female screwed hole 8 of inwall upper band is equipped with, screwed hole 8 is located at circular hole 6 away from the one end for expanding hole 7, and is connected with circular hole 6
Communicate.The axis of the screwed hole 8 and the dead in line of major axis 1, the diameter of screwed hole 8 are less than the diameter of circular hole 6.Screwed hole 8
Dock and communicate with the oilhole 14 in major axis away from one end of circular hole 6, the axis of oilhole 14 and the dead in line of screwed hole 8.
The expansion hole 7 is the conical bore coaxial with circular hole 6, and expand hole 7 to be located at major axis 1 away from one end of short axle 3 is which
Heavy caliber end, the diameter of the small-caliber end in the expansion hole 7 and the equal diameters of circular hole 6, and expand the small-caliber end and circle in hole 7
One end docking in hole 6.The major axis 1 away from the side wall of one end of short axle 3, four gap 9 with annular uniform arrangement, respectively
Gap 9 is the strip that extends of axis direction along major axis, and deep equality, and the setting of gap 9 is easy to major axis 1 to have to expand hole
7 one end can be expanded laterally, and the inwall clamping with 11 centre bore of rotor is fixed.The major axis 1 away from short axle 3 one
There is at the outer ledge of end chamfering 10, the assembling of major axis 1 and 11 centre bore of rotor is easy in the setting of chamfering 10.
The expansion 4 is configurable in expansion hole 7, is detachably connected with major axis 1.Expand 4 include expanding head main body 41 and with
