Embodiment
Below, be elaborated with reference to the linkage structure of drawings and Examples to enclosed compressor rotor of the present invention:
The same label of employing that component among the present invention are same as the prior art.
Shown in Fig. 2-4, a kind of linkage structure of enclosed compressor rotor, described compressor comprises housing 1, in the upper inside of housing 1 motor 40 is installed, at the downside of motor 40 compressor assembly 30 that is equipped with separated by a distance.Motor 40 is pressed on the inner peripheral surface that is fixed on cylindrical shell 11, and it is made up of stator 21, rotor 41 and rotary crankshaft 42 of being pressed into the center that is fixed on rotor 41 and transmitting rotating force etc.Compressor assembly 30 comprises cylinder 31, upper bearing 32 and lower bearing 33.The upside binding of upper bearing 32 is fixed with baffler 34, is used to reduce the noise that is produced by pressure difference from the compressed media gas of exhaust port discharge.Be provided with suction pipe 50 in the bottom of seal casinghousing 1.For making dielectric gas be discharged to seal casinghousing 1 outside by baffler 34, on loam cake 12, be provided with discharge tube 51, on loam cake 12, also be provided with the power-line terminal 52 that connects power line.The axis hole of rotor 41 is made into different diameter hole, and the aperture, upper end cooperates with the external diameter of bearing 44 greatly, and the aperture, lower end is less to be cooperated with bent axle 42.
Between the top of the bottom of loam cake 12 and motor 40, be provided with fixed support 43, fixed support 43 is fixedlyed connected with the interior circle of loam cake 12, and fixed support 43 is formed by disk 46 with at the cylinder 47 of its underpart, and disk 46 and cylinder 47 are integrally formed, the diameter of disk 46 is D, and the diameter of cylinder 47 is d.
In order to make fixed support 43 better fixing with the interior circle of loam cake 12, the diameter D of disk 46 is equal to or less than the internal diameter of loam cake 12.Be connected and fixed that support 43 cooperates with rotor 41 by bearing 44 and support rotor is rotated, bearing 44 is ball bearing or tapered roller bearing 45.Specifically, the diameter d of the cylinder 47 of fixed support 43 cooperates with the internal diameter of bearing 44, and bearing 44 external diameters cooperate with rotor 41 and the support rotor rotation.
The present invention is owing to be provided with fixed support 43 on the top of motor 40, and the shorten length of bent axle originally reduces the center of gravity of bent axle, also helps the stable operation of rotor.When compressor start, because disk is also fixedlyed connected with loam cake, so fixed support 43 is motionless, rotor 41 and bent axle 42 are rotated by the cylinder 47 of bearing 44 around fixed support 43.
