Abstract
The utility model relates to a rotary variable-capacitance aerostatic press. A motor is arranged on a base provided with a cylindrical inner casing, and an inner rotary body of which the tooth profile adopts equidistant short amplitude outer cycloid is arranged on an extending shaft of the motor; an outer rotary body adopts a circular arc tooth profile to be engaged with the inner rotary body and rotates following the inner rotary body; the bottom surface of the inner casing is provided with two arc-shaped flow passages which are not communicated and are communicated with an air chamber, and the two arc-shaped flow passages are corresponding to an end cover flow passage. In the process that the motor rotates and the inner rotary body and the outer rotary body are engaged, the volume of each volume chamber changes continuously to complete air suction and air exhaust. The aerostatic press has the advantages of small size, simple structure, large air exhaust amount and low noise, and can be widely used for oxygenation devices in aquaculture, storage industry, etc.
Description
The utility model relates to small-sized, especially miniature rotary volume aerostatic press.
Known rotary volume type aerostatic press has screw type, rolling-piston-type etc., and these compressor volumes are big, and the rotor surface that has is complicated curved surface, processing difficulties, and the operation noise that has is big etc.
It is little that the purpose of this utility model provides a kind of volume, simple in structure, the pressure height, and air displacement is big, the low aerostatic press of operation noise.
The purpose of this utility model is achieved in that on a support that has a cylinder type inner casing, motor directly is installed, the motor projecting shaft enters inner casing, on the axle inner rotary member is housed, external rotary member and inner rotary member engagement, and, is furnished with lining between cylindrical shape inner casing and the external rotary member with its rotation.Cylindrical shape inner casing bottom surface is provided with two not connected arc circulations, communicate with the air chamber that is located between inner casing and footing seat respectively, and corresponding with runner on the end cap, and the inner rotary member flank profil is equidistant curtate epicycloid, external rotary member is a circular arc profile, and inner rotary member axis and external rotary member axis have a throw of eccentric.
The inner rotary member number of teeth is G
1, 3≤G
1≤ 8, the number of teeth of external rotary member is G
2=G
1+ 1.
The motor rotation directly drives the internal rotor rotation, and external rotor is in company with rotation in the same way, and in engagement process, each cavity volume volume constantly changes, and finishes suction, exhaust.
The utility model is because the inner rotary member flank profil adopts equidistant curtate epicycloid, external rotary member adopts circular arc profile, external rotary member and inner rotary member engagement, and with its rotation, inner casing bottom surface and end cap are provided with corresponding runner, and communicate with air chamber respectively, make aerostatic press air pressure height of the present utility model, air displacement is big, and is simple in structure, running is steady, and noise is low.It is a kind of oxygen increasing equipment that is widely used in aquaculture, transportation, storage industry.If mix corresponding water pipe adapter, also can make water pump and use.
Introduce the utility model embodiment below.
