Description
Technical field:
The utility model relates to the Compressor Technology field, the rotary compressor that particularly a kind of cylinder rotates.
Background technique:
Present rotary compressor, its working principle is generally the rotor of doing the uniform speed rotation and is installed in the columniform cylinder, dispose one or several reciprocating blades again, to form the active chamber that the volume cycle changes, described active chamber is separated into entrance point and two air cavitys of outlet end by blade, utilize the cycle of active chamber to change, gas is imported by entrance point, send into outlet end again, reduce through the outlet end volume, reach the purpose of pressurized gas, then gas is discharged from the air outlet, promptly finish the circulation of a pressurized gas.Rotary compressor has compact structure, component and reaches characteristics such as long working life less, is widely used in room air conditioner, refrigerating appliance, car air conditioner and Ignitable gas devices etc.
Different with the Placement of rotor according to blade, rotary compressor can be divided into rolling piston compressor and swing-rotor compressor.Wherein, the blade of rolling piston compressor is slidedly arranged on the cylinder wall, and is tight against the rotor outer wall all the time under the spring force effect, because blade contacts for linear with the rotor outer wall, reveal unavoidably the joint of blade and rotor in the course of the work, thereby influence the gas compression effect; And in the working procedure, during rotor rotation,, can cause that heat up in the contacting point and wearing and tearing all the time with blade generation sliding friction.
Swing-rotor compressor as shown in Figure 1 is then because blade 4 and rotor 9 affixed being integral, compare with rolling piston compressor, the swing-rotor compressor does not need to be provided with spring assembly, part reduces, structure is more simple, and eliminated the friction and the leakage of 9 of blade 4 and rotors, improved the reliability and the compression efficiency of compressor.But, described swing-rotor compressor still has following defective: 1, the driving force of rotor 9 is generally provided by motor, motor output shaft is with the eccentric shaft 31 of power transmission to rotor 9, making described eccentric shaft 31 drive rotor 9 rotates, and make described blade 4 left and right sides reciprocally swingings, because the arm of force is shorter, so need the power of motor output bigger; When 2, rotating owing to rotor 9, rotor 9 outer walls contact cylinder 1 inwall all the time, and the frictional force of the two is bigger, the temperature of active chamber is raise, and easily cause wearing and tearing, influence the working life of compressor.
The model utility content:
The purpose of this utility model is to provide at the deficiencies in the prior art a kind of rotary compressor of cylinder rotation, compare with existing rotary compressor, rotary compressor described in the utility model is more laborsaving, and frictional force is littler between the parts that are in contact with one another and do relative motion, the temperature rise of compressor operating chamber is little, longer service life.
For achieving the above object, the utility model adopts following technological scheme:
The rotary compressor that a kind of cylinder rotates, it comprises cylinder and is inscribed within the ring that rolls of cylinder inner wall, described cylinder inner wall with roll the ring outer wall surround an active chamber, described active chamber is arranged on described cylinder by one and is separated into entry end and outlet end with the blade that rolls interannular, described entry end is provided with and is communicated with extraneous inlet, described outlet end is provided with and is communicated with extraneous outlet, it also comprises the dead axle that together is located in the cylinder, described dead axle outward successively fixed cover be provided with an eccentric wheel and a bearing, described roll the ring fixed cover be located at outside the described bearing; The casing wall of described cylinder is connected with motor output shaft.
Wherein, described entrance and exit is separately positioned on the casing wall of described cylinder, and runs through the casing wall of described cylinder respectively.
Or, the position of described entrance and exit is: described dead axle is a hollow shaft, and described inlet is arranged on the ring wall that rolls ring, and described eccentric wheel is along circumferentially offering groove, be provided with the passage of supplied gas circulation between described dead axle and groove, described groove is communicated with inlet; Described outlet is arranged on the casing wall of described cylinder and runs through described casing wall.
Wherein, be provided with the passage of many supplied gas circulations between described dead axle and groove.
Wherein, have guiding groove on the described cylinder inner wall, described blade one end is fixed on the described outer wall that rolls ring, and the other end is slidedly arranged in the described guiding groove rotationally.
Further, described guiding groove runs through the casing wall of described cylinder, and described blade stretches out the casing wall of described cylinder away from an end that rolls ring.
Or described blade and cylinder and roll being connected to of ring: described rolling offers chute on the ring; Described blade one end is slidingly installed in the described chute, and the other end is embedded swingably in the casing wall of described cylinder.
Further, the cell body degree of depth of described chute is stretched out the outer length of casing wall of described cylinder greater than blade.
Wherein, described outlet port is provided with an air valve.
The utility model beneficial effect is: it comprises cylinder and is inscribed within the ring that rolls of cylinder inner wall, described cylinder inner wall with roll the ring outer wall surround an active chamber, described active chamber is arranged on described cylinder by one and is separated into entry end and outlet end with the blade that rolls interannular, described entry end is provided with and is communicated with extraneous inlet, and described outlet end is provided with and is communicated with extraneous outlet; It also comprises the dead axle that together is located in the cylinder, and described dead axle is fixed sheathed outward and an eccentric wheel and a bearing successively, and the described ring fixed cover that rolls is located at outside the described bearing, and the casing wall of described cylinder is connected with motor output shaft; During work, power transmission is given cylinder, and cylinder rotation, and drive the described ring that rolls by blade and roll along cylinder inner wall makes the entry end of described active chamber and the cyclically-varying of outlet end volume and reaches the purpose of pressurized gas.Its beneficial effect is: 1, because cylinder described in the utility model is the active rotation cylinder, compare existing rotary compressor, its arm of force is longer, and then needed power is littler, thereby more laborsaving; 2, cylinder inner wall described in the utility model and roll between the ring outer wall and born a part by described bearing because of being in contact with one another the frictional force that also relative movement produced, thereby existing relatively rotary compressor, cylinder inner wall and the relative friction forces of rolling between the ring outer wall are less, the friction Temperature Rise of described active chamber is less, functional reliability improves, and the wearing and tearing that cause because of friction reduce, and increase the working life of compressor.
