The utility model belongs to the technical filed of a compressor, and provides a double eccentric flywheel structure direct linkage portable oil-free air compressor. The oil-free air compressor comprises a connecting shaft (2), a first connecting rod (5) and a second connecting rod (6). The first connecting rod (5) is connected with the second connecting rod (6) through the connecting shaft (2). The oil-free air compressor is characterized in that eccentric holes (11) and center holes (12) are arranged in a first eccentric flywheel (1) and a second eccentric flywheel (9), two ends of the connecting shaft (2) which connects the first connecting rod (5) and the second connecting rod (6) are respectively connected with the first eccentric flywheel (1) and the eccentric hole (11) of the second eccentric flywheel (9), the center hole (12) of the second eccentric flywheel (9) is connected with an electric motor (10), the first connecting rod (5) is connected with a first piston (4) through a first piston sheath (3), and the second connecting rod (6) is connected with a second piston (8) through a second piston sheath (7). The oil-free air compressor is low in vibration and power dissipation, and can stably work under high pressure.
Description
Technical field
The utility model provides a kind of pair of eccentric free wheel structure direct connection portable oilless air compressor, belongs to the Compressor Technology field.
Background technique
Existing direct connection reciprocating-piston type oil-less air compressor, include cylinder, piston, connecting rod, couple axle and motor etc., because the gyration center of piston type air compressor connecting rod and motor shaft be not on same straight line, so must there be an eccentric wheel to come counterweight, but traditional compressor single cylinder or twin-tub all only have an eccentric wheel, are unfavorable for the balance vibrations.
The model utility content
According to above the deficiencies in the prior art, the technical problems to be solved in the utility model is: the direct connection portable oilless air compressor that a kind of pair of eccentric free wheel structure, low vibration, high electric efficiency are provided.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of pair of eccentric free wheel structure direct connection portable oilless air compressor, comprise coupling shaft, first connecting rod and second connecting rod, first connecting rod is connected coupling shaft with second connecting rod and connects, it is characterized in that: be provided with eccentric opening and center hole on the first eccentric free wheel and the second eccentric free wheel, connecting first connecting rod is connected the coupling shaft two ends and connects respectively the eccentric opening of the first eccentric free wheel and the second eccentric free wheel with second connecting rod, the center hole of the second eccentric free wheel connects motor, first connecting rod connects first piston by the first piston sheath, and second connecting rod connects the second piston by the second piston sheath.
There is an eccentric free wheel at the two ends of two connecting rod shafts of air compressor, can better balance shake, the inertial energy-accumulating that adopts simultaneously two eccentric free wheels to bring is larger, effectively reduced the output of motor power consumption, the accumulation of energy advantage that double eccentric wheel brings can allow compressor stable operation under higher pressure.
Described the first eccentric free wheel and the second eccentric free wheel are symmetrical arranged.Symplex structure can better support with balance by inertia and vibration that crank and connecting rod movement brings, effectively reduces the output of motor power consumption.
The beneficial effect that the utility model has is: the vibrations of the described pair of eccentric free wheel structure direct connection portable oilless air compressor are low, low in energy consumption, compressor can be under higher pressure stable operation.
Description of drawings

Among the figure: 1, the first eccentric free wheel; 2, coupling shaft; 3, first piston pin; 4, first piston; 5, first connecting rod; 6, second connecting rod; 7, the second wrist pin; 8, the second piston; 9, the second eccentric free wheel; 10, motor; 11, eccentric opening; 12, center hole.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1, a kind of pair of eccentric free wheel structure direct connection portable oilless air compressor, comprise coupling shaft 2, first connecting rod 5 and second connecting rod 6, first connecting rod 5 is connected with second connecting rod by coupling shaft 2 connections, be provided with eccentric opening 11 and center hole 12 on the first eccentric free wheel 1 and the second eccentric free wheel 9, coupling shaft 2 two ends that connection first connecting rod 5 is connected with second connecting rod connect respectively the eccentric opening 11 of the first eccentric free wheel 1 and the second eccentric free wheel 9, the center hole 12 of the second eccentric free wheel 9 connects motor 10, first connecting rod 5 connects first piston 4 by first piston sheath 3, and second connecting rod 6 connects the second piston 8 by the second piston sheath 7.9 one-tenth symplex structures of the first eccentric free wheel 1 and the second eccentric free wheel.
Working principle and using process:
Cardinal principle of the present utility model is that motor 10 drives 9 motions of the second eccentric free wheel, the second eccentric free wheel 9 rotates around motor center, the first connecting rod 5, second connecting rod 6 and the eccentric free wheels 1 that are linked to each other by coupling shaft 2 that drive simultaneously on this eccentric opening 11 are done identical rotatablely moving, the center hole 12 of cause the first eccentric free wheel 1 and the second eccentric free wheel 9 is concentric, and the eccentric opening 11 of two eccentric free wheels has certain distance with center hole 12.Therefore, be the linear reciprocating motion of first piston 4 in cylinder by connecting rod with the eccentric rotary conversion of motion of first connecting rod 5, the eccentric rotary conversion of motion of second connecting rod 6 is the linear reciprocating motion of the second piston 8 in cylinder.Cause two eccentric free wheels are the two ends at connecting rod shaft 2, and certain distance is arranged, form symplex structure, symplex structure can better support inertia and the vibration that is brought by crank and connecting rod movement with balance, effectively reduce the output of motor power consumption, the accumulation of energy advantage that double eccentric wheel brings can allow compressor stable operation under higher pressure.
The above, it only is preferred embodiment of the present utility model, be not to be the restriction of the utility model being made other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment does, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
