Embodiment
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, refrigerator
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
The eccentric shaft 12 being connected including main shaft 10 and with main shaft 10.
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 assembling
Raised and threaded hole, fitting groove 5 are semi-circular groove, and assembling protrusion is semi-cylindrical hill.Assembling 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 clump weight 3 projects to both positions of cylindrical shell 1 and is located at 1 phase of cylindrical shell
To both sides, realize the purpose of 3 balance rotating inertia force of clump weight and reciprocal inertia force.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 opposite side of cylindrical shell 1 is internally provided with guide rod 2, specifically, the side of one end connecting cylinder housing 1 of guide rod 2
Wall, the other end of guide rod 2 is hanging, the lower face keeping parallelism of guide rod 2 and cylindrical shell 1.Guide groove is provided with clump weight 3, is matched somebody with somebody
Pouring weight 3 is slidably connected through guide groove and guide rod 2.Clump weight 3 can be slided relative to guide rod 2, and guide rod 2 through guide groove to clump weight 3
Positioning, when bent axle rotates, guide rod 2 can synchronous drive clump weight 3 rotate.The other end of guide rod 2 is removably connected with block 13,
Assembling, dismounting in order to clump weight 3.In the present embodiment, block 13 is nut, the other end of nut thread connection guide 2.
Opening up fluted 8 on clump weight 3, the side wall of cylindrical shell 1 is provided with boss 7, one end connecting groove 8 of spring 4,
The other end connection boss 7 of spring 4.Boss 7 can be stretched into groove 8, and clump weight 3 is fan annular, and the clump weight 3 for fanning annular can be with
The inner wall fitting of cylindrical shell 1, when bent axle is rotated with maximum speed, under the influence of centrifugal force, clump weight 3 reaches clump weight 3
To extreme position, clump weight 3 can be bonded the inner wall of cylindrical shell 1, and boss 7 can be stretched into groove 8, and spring 4 may contract to recessed
In groove 8, to improve the stroke that clump weight 3 is slided along guide rod 2, to facilitate the type selecting of clump weight 3 and spring 4 to arrange in pairs or groups.
Cylindrical shell 1 offers several oilholes 9, with the rotation of cylindrical shell 1, under the influence of centrifugal force, oils
The machine oil of mechanism can be got rid of in cylindrical shell 1 from oilhole 9, play the role of lubricating this component.
The adaptive balance weight assembly of refrigerator frequency-changeable compressor bent axle of the present embodiment, itself is detachable structure, easy to fill
Match somebody with somebody, dismantle, clump weight 3 and spring 4 can be replaced, and the quality of clump weight 3 and the rigidity of spring 4 be replaced by calculating, one is matched somebody with somebody
Restructuring part can be adapted for the frequency-changeable compressor of different model.With the raising of speed of crankshaft, the centrifugal force of clump weight 3 increases,
Clump weight 3 is displaced outwardly along guide rod 2, and clump weight 3 compresses spring 4, until clump weight 3 centrifugal force and be subject to the elastic force of spring 4
Balance, the position of clump weight 3 reaches stable state.Speed of crankshaft is higher, and rotating inertia force and reciprocal inertia force are bigger, clump weight
3 offset is also bigger, and the torque that the eccentric moment of clump weight 3 produces rotating inertia force, reciprocal inertia force is put down into Mobile state
Weighing apparatus.
