Abstract

The invention discloses a gear type air compressor which is composed of a first-stage compressor body and a second-stage compressor body, wherein the first-stage compressor body comprises a shell and upper and lower sets of mutually meshed excircle gears in the shell; gear teeth of the excircle gears are shaped as circular arc and are excircles of dedendum circles; the gear teeth of the two sets of excircle gears are excircles with each other; two ends of the shafts of the two sets of excircle gears are movably connected onto a casing; gears are respectively arranged at the same ends of the shafts passing through the casing; the two are in meshed transmission, wherein one shaft is in transmission connection with a power device; an air inlet is arranged at one side of the shell; an air outlet is arranged at the other side of the shell; and the air outlet of the first-stage compressor body is communicated with the air inlet of the second-stage compressor body. According to the invention, because of not having accessories, such as a fan, a valve and the like, the energy consumption is very low; rotational compressed air flows rapidly, so that heat cannot be accumulated, and a cooling effect is played; in addition, oil contamination is not contained in the compressed air, so that environmental pollution can be avoided.

Description

Gear type air compressor

Technical field

The present invention relates to the air compressor field, be specifically related to gear type air compressor.

Background technique

Existing air compressor generally is a piston compressor, and through the to-and-fro motion of piston, the switching of valve realizes compressed-air actuated purpose; This energy consumption of compressor is too big, and produces big calorimetric in the course of the work, need lubricate owing to piston simultaneously; Have greasy dirt in the pressurized air; Befouling environment, with the low energy consumption of present proposition, pollution-free disagreing.

Summary of the invention

The technical problem that the present invention will solve provides gear type air compressor, and is simple in structure, low energy consumption, the low pollution, and can not produce big calorimetric in the course of the work.

The present invention realizes through following technological scheme:

Gear type air compressor, one-level compressor body comprise shell and the two groups of intermeshing circumcircle gears up and down that are positioned at shell, and the gear teeth of said circumcircle gear are circular arc; It is the circumcircle of root circle; The gear teeth of two groups of circumcircle gears are circumcircle each other, and the axle two ends of said two groups of circumcircle gears are movably connected on the casing, and the axle that passes housing part is respectively equipped with gear with end; Both engagement driving; Wherein axle and power plant are in transmission connection, and shell one side is provided with suction port, and opposite side is provided with the air outlet.

The further improvement project of the present invention is that the gear teeth quantity of said circumcircle gear is 3.

The present invention further improvement project is that the gear teeth of said circumcircle gear and outer casing inner wall gap are less than 0.2mm.

The further again improvement project of the present invention is to comprise the two stage compressor body, the suction port of the air outlet connection two stage compressor body of one-level compressor body.

The further again improvement project of the present invention is that the axle of said circumcircle gear is belt or gear or shaft coupling with being in transmission connection of power plant.

The present invention compared with prior art has following obvious advantage:

1, the present invention does not have annexes such as fan, valve owing to be through the circumcircle gear rotation dynamic pressure that two groups seal each other in the shell air that contracts, and energy consumption seldom.

2, owing to be to rotate compression, pressurized air flows fast, does not only accumulate heat, plays cooling effect on the contrary.

3, do not have greasy dirt in the pressurized air, can not pollute environment.

Description of drawings

Fig. 1 is a front view of the present invention.

Fig. 2 is the sectional drawing of the A-A of Fig. 1.

Embodiment

Like Fig. 1, shown in Figure 2, one-level compressor body 1 comprises shell 11 and two groups of

intermeshing circumcircle gear

12,12 ˊ up and down that are positioned at shell 11, and the gear teeth 121 of said circumcircle gear are circular arc; It is the circumcircle of root circle; The gear teeth 121,121 ˊ of two groups of circumcircle gears are circumcircle each other, and axle 122, the 122 ˊ two ends of said two groups of circumcircle gears are movably connected on the casing 1, and the axle that passes housing part is respectively equipped with

gear

13,13 ˊ with end; Both engagement driving; Wherein axle and power plant 14 are in transmission connection, and shell one side is provided with suction port 111, and opposite side is provided with air outlet 112.

The gear teeth 121 quantity of said circumcircle gear are 3.

The gear teeth 121 of said circumcircle gear and shell 11 inwall gaps are less than 0.2mm.

Also comprise two stage compressor body 2, the air outlet 112 of one-level compressor body 1 is communicated with suction port 111 ˊ of two stage compressor body 2.

The axle 122 and being in transmission connection of power plant 14 of said circumcircle gear are belt or gear or shaft coupling.
