This utility model relates to a kind of low energy consumption home appliance compressor linkage, and including piston component and connecting rod, described piston component is fastenedly connected with described connecting rod；Described con-rod only is sequentially provided with powder metallurgy layer and wear-resisting enhancement layer from inside to outside, is arranged with elastomer in the powder metallurgy layer of described con-rod only both sides boss；Using the connecting rod of powder metallurgy pressing, quality can alleviate 30%, makes connecting rod reciprocal inertia force be greatly lowered；It is arranged with elastomer in the metallurgical powder layer of con-rod only both sides boss, it is possible to effectively reduce inertia force, strengthens fatigue resistance；On metallurgical powder layer, compound one layer of fibre reinforced layer, improves the stiffness of connecting rod, strengthens the counter-bending deformability of connecting rod；The vibration reduced also makes noise alleviate simultaneously；There is life-span length, improve work efficiency, the beneficial effect such as environmental.
Description
Technical field
This utility model relates to field of powder metallurgy, particularly relates to a kind of low energy consumption home appliance compressor linkage.
Background technology
In home appliance compressor, connecting rod is used for connecting piston and bent axle, and active force suffered by piston is passed to bent axle, and the reciprocating motion of piston is changed into the rotary motion of bent axle；Connection rod set is made up of gonnecting rod body, connecting rod cap, lining of connecting rod small end, big end bearing shell and connecting-rod bolts (or screw) etc.；Connection rod set is born gas load that piston pin transmits and itself swings and the effect of piston set reciprocal inertia force, and the size and Orientation of these power is all periodically variable, and therefore connecting rod is by alternate load effects such as compression, stretchings；Connecting rod must have enough fatigue strength and the rigidity of structure；Fatigue strength is not enough, often causes gonnecting rod body or connecting-rod bolts fracture, and then produces the major accident that complete machine destroys；If insufficient rigidity, then can cause the mistake circle deformation of body of rod flexural deformation and big end, cause the eccentric wear of piston, cylinder, bearing and crank-pin etc.；The fatigue rupture of compressor connecting bar is one of principal element affecting home appliance compressor quality, whether the fatigue strength of connecting rod meets requirement is one of necessary concern of designer, if in motor process, the resistance of motion is excessive will result in connecting rod and bent axle is impaired, long-term high load capacity easily causes connecting rod wear and rupture after using, causes danger, and affects compressor power consumption and efficiency.
Utility model content
This utility model purpose is to provide a kind of low energy consumption home appliance compressor linkage to overcome the deficiencies in the prior art, has the beneficial effects such as lightweight, wear-resistant and high-strength anti-fatigue.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of low energy consumption home appliance compressor linkage, including piston component and connecting rod, described piston component is fastenedly connected with described connecting rod；Described con-rod only is sequentially provided with powder metallurgy layer and wear-resisting enhancement layer from inside to outside, is arranged with elastomer in the powder metallurgy layer of described con-rod only both sides boss.
Improving further as this utility model, described elastomer is solid circle shape or entity spiral spring-like.
Improving further as this utility model, described elastomer material is nonmetallic materials.
Improving further as this utility model, described wear-resisting enhancement layer is carbon fiber layer.
Due to the utilization of technique scheme, this utility model compared with prior art has the advantage that
This utility model scheme provides a kind of low energy consumption home appliance compressor linkage, uses the connecting rod of powder metallurgy pressing, and quality can alleviate 30%, makes connecting rod reciprocal inertia force be greatly lowered, and reduces compressor loss；It is arranged with elastomer in the metallurgical powder layer of con-rod only both sides boss, it is possible to effectively reduce inertia force, strengthens fatigue resistance；On metallurgical powder layer, compound one layer of fibre reinforced layer, improves the stiffness of connecting rod, strengthens the counter-bending deformability of connecting rod；The vibration reduced also makes noise alleviate simultaneously；There is life-span length, save energy and reduce the cost, improve work efficiency, the beneficial effect such as environmental.
