Description
Technical field
The utility model relates to a kind of straight connection type scroll compressor.
Background technique
Scroll compressor is a kind of new and effective fluid machinery after piston compressor and helical-lobe compressor, its scroll compressor mechanism main structure comprises quiet whirlpool dish and a movable orbiting scroll, by cooperating of quiet whirlpool dish and movable orbiting scroll, realization is to the compression effectiveness of gas.
The scroll compressor of prior art, its structure is mainly:
1, drive spindle operation by drive motor by belt pulley, as shown in Figure 1, the scroll compressor of this structure, it comprises that quiet whirlpool coils 1 ＇, movable orbiting scroll spring bearing 2 ＇, forebay 3 ＇, eccentric shaft step bearing 4 ＇, main bearing 5 ＇, rear bay 6 ＇, belt pulley 7 ＇, supplementary bearing 8 ＇, main shaft 9 ＇, main equilibrium block 10 ＇ and movable orbiting scroll 11 ＇, main shaft 9 ＇ of compressor reach outer belt pulley 7 ＇ that also install of rear bay 6 ＇ at compressor rear portion thereon, belt pulley also is installed on the live axle of motor, both connect by belt, therefore work as the motor rotation and just rotate by main shaft 9 ＇ of above-mentioned belt gear drive compression machine, thereby realize that compressor is to the compression of gas.But, because main shaft 9 ＇ of belt transmissioning mode lower compression machine are subjected to belt to the radial pressure of belt pulley 7 ＇, and the power of transmission is more big, this radial pressure is just more big, by the balance of power and moment as can be known main bearing 5 ＇, supplementary bearing 8 ＇ of compressor inside just be subjected to a pressure radially, cause shaft strength to worsen; The transmission efficiency of another fermentation belt pulley kind of drive is low, and loss is bigger, causes the performance of compressor to reduce; Install when belt simultaneously and easily cause belt slippage when improper or produce abnormal sound; Vibration during in addition owing to belt transmission makes the vibration of machine system and noise increase.
2, motor direct connection scroll compressor; by drive motor and the scroll compressor associated mode by coupling; as shown in Figure 2; the scroll compressor of this structure; comprise vortex main frame 12 ＇; vortex main frame main shaft stretches out bonnet and is connected with drive motor 13 ＇; thereby the drive motor main shaft rotates and drives vortex main frame 12 ＇ running realization to the air compression effects; on the vortex main frame main shaft secondary equilibrium block is housed; simultaneously; it also is equipped with main equilibrium block usually in order to regulate the dynamic balancing relation of compressor on drive motor main shaft.Vortex main frame main shaft and drive motor main shaft link together by coupling 14 ＇, half part of coupling 14 ＇ is housed on the vortex main frame main shaft, second half part of coupling 14 ＇ is installed on the drive motor main shaft, when motor rotates, thereby via the connection drive compression machine pressurized gas of coupling 14 ＇.Adopt the Placement of the major-minor equilibrium block of this coupling and main shaft to seem to be simple and easy to dress and the surface is gone up highly stable, but in the concrete manufacturing installation process of reality, its real structure and complexity thereof, and be difficult for balance, component are many again, main frame is (through starting repeatedly) after operation a period of time, cause coupling 14 ＇ about part connect loosening and the gap bigger, bearing to main frame during starting is subjected to a pressure radially, cause shaft strength to worsen, make the vibration of machine system and noise increase.
The model utility content
Technical problem to be solved in the utility model is to overcome deficiency of the prior art and a kind of straight connection type scroll compressor is provided, this straight connection type scroll compressor effective performance height, vibrations are little, amount of parts is few, simple and reasonable, fabricating cost is low and safe and reliable.
The technical scheme in the invention for solving the above technical problem is: a kind of straight connection type scroll compressor comprises vortex main frame and drive motor; The vortex main frame comprises quiet whirlpool dish and movable orbiting scroll, and quiet whirlpool dish and movable orbiting scroll cooperate, and the movable orbiting scroll bearing is installed in the movable orbiting scroll; Drive motor comprises motor shaft, fan, bonnet, and bonnet is stretched out in the rear end of motor shaft, and fan is fixed on the rear end of motor shaft; It is characterized in that: the front end of described motor shaft is equipped with movable orbiting scroll and adjusts piece, and movable orbiting scroll is adjusted piece and is connected with the movable orbiting scroll bearing.
The utility model also comprises equilibrium block, and equilibrium block is fixed on the motor shaft rear end, and links to each other with fan.
Equilibrium block described in the utility model is between bonnet and fan.
The utility model compared with prior art, have following advantage and effect: the motor shaft of drive motor directly is connected with movable orbiting scroll, be that the main shaft of vortex main frame and the motor shaft of drive motor are one, motor shaft and movable orbiting scroll direct connection, replace traditional belt sheave structure and lean on coupling to drive the structure of main frame, realize that main frame does not have axiation, scroll compressor main frame and motor are become one, the machine that really becomes one, motor shaft directly drive the scroll compressor running and realize the air compression effects.The utility model can make drive motor more stable and compact with connecting of vortex main frame; be seamless connection; protected bearing to avoid the moment loading of radial force, avoided compressor abnormal sound to occur skidding or producing, the main frame component reduce; lower vibration and the noise of machine system; the effective performance height of machine, safe and reliable, lowered the overall volume of product greatly; simple and reasonable, fabricating cost is low.
