Specific implementation mode
As shown in Figures 1 to 4, the present embodiment provides a kind of adaptive balance weight assembly of refrigerator frequency-changeable compressor bent axle, refrigerators
The adaptive balance weight assembly of frequency-changeable compressor bent axle includes the components such as bent axle, cylindrical shell 1, clump weight 3 and spring 4.Wherein, bent axle
Including main shaft 10 and the eccentric shaft being connect with main shaft 10 12.
The side lower face of cylindrical shell 1 is provided with fitting groove 5 and screw hole 6, and the top of eccentric shaft 12 is provided with assembly
Protrusion and threaded hole, fitting groove 5 are semi-circular groove, and assembly protrusion is semi-cylindrical hill.Assembly protrusion is connected together fitting groove 5,
So that cylindrical shell 1 is positioned with eccentric shaft 12.Positioning makes cylindrical shell 1 be arranged with 10 coaxial line of main shaft.Positioning also makes partially
Mandrel 12 projects to the position of cylindrical shell 1 and both positions that clump weight 3 projects to cylindrical shell 1 are located at 1 phase of cylindrical shell
To both sides, realize clump weight 3 balance rotating inertia force and reciprocal inertia force purpose.It is fixed in cylindrical shell 1 and eccentric shaft 12
On the basis of position, screw 11 is threadedly coupled threaded hole through screw hole 6, so that eccentric shaft 12 is detachably connected to cylindrical shell 1.
The other side of cylindrical shell 1 is internally provided with guide rod 2, specifically, the side of one end connecting cylinder shell 1 of guide rod 2
