Abstract
The invention discloses an electric scroll compressor, relating to the technical field of manufacturing of compressors. The electric scroll compressor comprises an eccentric shaft which is provided with a motor rotor assembly in a penetrating manner, wherein balance blocks are respectively arranged at the parts, which are close to the two ends of the motor rotor assembly, of the eccentric shaft; the balance blocks are fixed on the eccentric shaft through cylindrical pins. Compared with the prior art, the electric scroll compressor has the advantages that the problem that the installation manufacturability of the motor rotor balance blocks of an existing electric scroll compressor is poor can be solved.
Description
Technical field
The present invention relates to Compressor Manufacturing technical field, especially a kind of tool for electric scroll compressor
There is the scroll compressor that balancing rotor is fast.
Background technique
At present, electric scroll compressor is more and more generally applied on Vehicular air-conditioner compressor; There is a kind of electric scroll compressor, this electric scroll compressor comprises by bearing support and is contained in the dynamic and static scroll assembly on casing, dynamic and static scroll assembly is connected with the Rotor Assembly that is provided with motor stator and rotor by eccentric shaft, at the two ends of Rotor Assembly, equilibrium block is housed.Because Rotor Assembly used is outsourcing piece, when general assembly, normally first on Rotor Assembly, install after equilibrium block, then eccentric shaft and Rotor Assembly are assembled.There are the following problems in process of production for this mode that equilibrium block is installed on Rotor Assembly: if leave preformed hole on the Rotor Assembly of outsourcing, equilibrium block can be installed on preformed hole; If but on rotor, there is no preformed hole, and cannot carry out equilibrium block installation, and to manufacturer's customization, producing increasing, mounting process is poor.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of electric scroll compressor, and it can solve the poor problem of existing electric scroll compressor motor rotor balance weight mounting process.
The technological scheme that technical solution problem of the present invention adopts is: this electric scroll compressor comprises the eccentric shaft that is coated with Rotor Assembly, and described eccentric shaft is respectively equipped with equilibrium block in nearly described Rotor Assembly two ends place.
In above-mentioned electric scroll compressor technological scheme, technological scheme can also be more specifically: described equilibrium block is fixed on described eccentric shaft by straight pin.
Further, described straight pin is elastic cylindrical pin.
Owing to having adopted technique scheme, the present invention compared with prior art, the beneficial effect having is: because equilibrium block is fixed on described eccentric shaft by straight pin, Rotor Assembly outsourcing is not being needed to special customization and buying both ends of the surface and leave preformed hole folding Rotor Assembly, the good manufacturability of installing, reduces production costs.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the structural representation of the eccentric shaft that equilibrium block is housed of the embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
Electric scroll compressor as depicted in figs. 1 and 2 comprises that the eccentric shaft 1 that is provided with the Rotor Assembly of motor stator 5 and rotor 4 and is provided with Rotor Assembly assembly department installed Rotor Assembly, the two ends place of the nearly Rotor Assembly of the present embodiment on eccentric shaft 1 is respectively installed with two equilibrium blocks 2, and equilibrium block 2 is by being fixed on eccentric shaft 1 through the straight pin 3 of its sidewall and eccentric shaft 1.
When general assembly, at one end of the Rotor Assembly assembly department of eccentric shaft 1 suit lastblock equilibrium block 2, then by equilibrium block 2 being fixed on eccentric shaft 1 through the straight pin 3 of its sidewall and eccentric shaft 1, the straight pin of the present embodiment is elastic cylindrical pin; Rotor Assembly is sleeved on Rotor Assembly assembly department and makes its end face near equilibrium block 2 again; Then on the Rotor Assembly assembly department of nearly Rotor Assembly other end, install another piece equilibrium block 2.
Claims (3)
1. an electric scroll compressor, comprises the eccentric shaft (1) that is coated with Rotor Assembly, it is characterized in that: described eccentric shaft (1) is respectively equipped with equilibrium block (2) in nearly described Rotor Assembly two ends place.
