Abstract
The utility model provides an air compressor with double rotary cylinders, which comprises a front end cover, a back end cover, outer shells, rotary cylinders, a piston, an eccentric axis, an air inlet and an air outlet. The inner parts of the outer shells are respectively provided with a rotary cylinder, the inner parts of the rotary cylinders are respectively provided with a piston, and the inner parts of the pistons are respectively provided with an eccentric axis. The upper end of the outer shell is respectively provided with the air inlet, and the lower end is respectively provided with the air outlet. The utility model has the advantages of simple structure, low noise, small starting current, stable operation, a not easily breaking eccentric axis, long service life and high ratio of gas and work. The utility model can realize two-stage air compression and form industrial production, and is easy to produce.
Description
Technical field
The utility model relates to a kind of air compressor, particularly relates to a kind of air compressor with double rotary cylinder.
Background technique
Along with the continuous progress of scientific and technological level, people are also more and more higher to the technical requirements of air compressor.At present, the air compressor that people generally use all only has single commentaries on classics cylinder, and the air compressor of this structure not only noise is big, and inrush current is big, galloping, and running time one is long, and its eccentric shaft ruptures easily, causes its running life short.The inventor being through long-term specializing in and testing, and updates and improves, and develops a kind of desirable air compressor, to satisfy the demands of consumers.
The model utility content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of simple in structure, double rotary cylinder air compressor that inrush current is little is provided.This compressor not only noise is low, and running is steady, long service life.
For achieving the above object, the technological scheme that the utility model adopted is: the utility model comprises front and rear cover 1, shell 8, changes cylinder 2, piston 7, eccentric shaft 5 and 6, suction port 10, relief opening 11 and 12, respectively be provided with one in the described shell 8 and change cylinder 2, change in the cylinder 2 and respectively be provided with a piston 7, respectively be provided with an eccentric shaft 5,6 in the piston 7, the upper end of described shell 8 respectively is provided with a suction port 10, and its bottom respectively is provided with a relief opening 11,12.
Be provided with bearing 3-1 between described shell 8 and the commentaries on classics cylinder 2, be provided with bearing 4 between described piston 7 and the eccentric shaft 5,6, be provided with bearing 3-2 between described front and rear cover 1 and the eccentric shaft 5,6.
Described eccentric shaft 5 and eccentric shaft 6 connect by coupling 9.
Described bearing 3-1,3-2 are ball bearing.
Described bearing 4 is a roller bearing.
The utility model compared with prior art has the following advantages: 1, the utility model is simple in structure, noise is low; 2, inrush current is little, running is steady; 3, eccentric shaft easy-rupturing not, long service life; 4, the qigong can realize the two-stage air compression than high; 5, be easy to make, can form industrialization production.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the sectional view of Fig. 1 along the A-A direction.
Embodiment
Below in conjunction with accompanying drawing structure of the present utility model and working principle are elaborated.
As Fig. 1, shown in Figure 2, the utility model comprises two cover front and rear covers 1, two cover shells 8, two are changeed cylinder 2, two pistons 7, two eccentric shafts 5 and 6, the upper end of described shell 8 respectively is provided with a suction port 10, its bottom respectively is provided with a relief opening 11,12, respectively be provided with one in the described shell 8 and change cylinder 2, be provided with bearing 3-1 between shell 8 and the commentaries on classics cylinder 2, respectively be provided with a piston 7 in the described commentaries on classics cylinder 2, respectively be provided with an eccentric shaft 5 in the piston 7,6, described piston 7 and eccentric shaft 5, be provided with bearing 4 between 6, connect described front and rear cover 1 and eccentric shaft 5 between described eccentric shaft 5 and the eccentric shaft 6 by coupling 9, be provided with bearing 3-2 between 6.Described bearing 3-1,3-2 adopt ball bearing and are respectively 4, and described bearing 4 is that roller bearing and quantity are two.
During this double rotary cylinder air compressor work, driven by motor eccentric shaft 5,6 do and are rotated counterclockwise, eccentric shaft 5,6 drive piston 7 rotations, piston 7 drives to control oneself when commentaries on classics cylinder 2 rotates together and moves reciprocatingly simultaneously, when piston 7 forwards suction port 10 positions to, air compressor sucks air, 7 pairs of air of piston compress, when piston 7 forwarded relief opening 11 positions to, air compressor was discharged air from relief opening 11, and this moment, relief opening 12 was closed, when forwarding suction port 10 positions to, repeats in piston 7 above-mentioned motion again, this moment, relief opening 11 was closed, relief opening 12 exhausts, and 7 pairs of air of piston compress continuously like this, exhaust, air compressor is when suction port 10 is air-breathing, relief opening 11,12 alternately exhausts make air compressor realize the two-stage air compression in a circular movement, have improved the usefulness of air compressor.
In sum, the utility model double rotary cylinder air compressor structure is simple, and inrush current is little, and running is steady, and noise is low, long service life, and this eccentric shaft rotates the inflation action that a circumference can produce twice air compression, makes air compressor have more usefulness.
