Description

Weight reduced type air compressor

Technical field

The utility model is a kind of Weight reduced type air compressor.

Background technique

Consult Fig. 6 and Fig. 7, show an air compressor of commonly using 8, this air compressor 8 comprises a pedestal 81, be combined in a compression cylinder 82 on this pedestal, be assembled in the motor 83 on this pedestal and driven by this motor 83 and at the interior reciprocating piston body 84 of this compression cylinder 82.Seeing through motor 83 drives piston body interior reciprocating to complete the discharge of suction, compression and superheated steam of gas at compression cylinder 82.

Generally speaking, it is reciprocating that the motor 83 of commonly using air compressor 8 orders about piston body by the transmission of a gear mechanism 85 and a crank mechanism.This gear mechanism 85 comprises the first gear (former moving gear) 851 being installed in motor 83 axles 831 and one second gear (driven gear) 852 being meshed with the first gear 851, and crank mechanism comprises a gravity block 861, one axostylus axostyle 862 and a connecting rod 863, one end of axostylus axostyle 862 is passed the second gear 852 and is arranged in an axis hole 810 set on pedestal 81, in axis hole 810, be typically provided with a bearing 811, bearing 811 is the shape structure of wholecircle shape, and one end of connecting rod 863 is hubbed at the circular hole 843 on the end 842 of piston rod 841 of piston body, because connecting rod 863 is eccentric with respect to axostylus axostyle 862, in the time that the second gear 852 is driven by the first gear 851, piston body will be interior reciprocating at compression cylinder 82.

But, commonly use the piston body of air compressor 8 in the interior reciprocating process of compression cylinder 82, usually have the generation of amoeboid movement, so that the working life that affects the efficiency of air compressor and reduce this air compressor.After designer's further investigation, find that one of reason comes from long the causing of distance between compression cylinder 82 and pedestal 81, that is, as shown in Figure 7, because gear mechanism 85 is located at the cause between compression cylinder 82 and pedestal 81, between compression cylinder 82 center and pedestal 81 inner side edges, there is a distance of growing (D), due to this existence of long distance (D), cause the athletic meeting of the centrifugal direction of connecting rod 863 to affect widely the rotation of axostylus axostyle 862, make when piston body is in the time moving back and forth, provide the inwall of the axis hole 810 that axostylus axostyle 862 installs a bit first to form wearing and tearing at certain because of stressed inequality, again after axis hole 810 wearing and tearing, the rotation (as shown in the label A of Fig. 8) of this axostylus axostyle 862 just forms the motion in the non-fixed point center of circle, once produce this kind of phenomenon, the rotation (as shown in the label C of Fig. 8) of this connecting rod 863 is also along with forming non-circular motion, and then make the valve head of piston body in the time moving back and forth in compression cylinder 82, just can produce amoeboid movement (as shown in the dotted line of Fig. 7), cause the bearing in valve head and the axis hole of piston body easily to destroy, life-span reduces.
