The compression assembly of existing rotary compressor and the mode that is connected and fixed of main casing adopt respectively: a) cylinder 23 directly welds means of fixation with main casing 1, sees accompanying drawing 1; B) main bearing 7 directly welds means of fixation with main casing 1, sees accompanying drawing 2; C) whole frame 23 of sheet metal and main casing 1 welding, cylinder 9 is connected and fixed by nut and whole frame 23, sees accompanying drawing 3, and 22 among the above figure is soldering point.
When adopting a) and b) during mode, the cylinder vane slot distortion of rotary compressor is bigger, and in order to guarantee the rotary compressor reliability of operation, the width gap between respective cylinder vane slot and the slide plate is set bigger, but, but bring the problem of rotary compressor decreased performance; When adopting c) during mode, though can solve a) and b) problem brought of mode,, the structure of cylinder of compressor and rigidity are all relatively poor, and the gap of electric machine assembly also is difficult to guarantee.
The model utility content
The cylinder fixed mechanism of the rotary compressor that the purpose of this utility model aims to provide that a kind of simple and reasonable, cylinder vane slot distortion is little, the overall efficiency of the good rigidly of cylinder, intensity height, compressor is high is to overcome deficiency of the prior art.
Press the cylinder fixed mechanism of a kind of rotary compressor of this purpose design, comprise the electric machine assembly and the compression assembly that are arranged in the housing, housing comprises upper shell, main casing and lower shell body, compression assembly comprises cylinder, is installed in the main bearing and the supplementary bearing of cylinder upper and lower end face, it is characterized in that being welded with in the main casing supporting element more than three, cylinder is fixedlyed connected with supporting element by bolt.
Described supporting element is distributed in the main casing, an end of supporting element and the welding of the inwall of main casing, and resistance welding or carbon dioxide gas arc welding mode are adopted in welding.
Described supporting element is dustpan shape, and its edge is provided with flange.
The other end of described supporting element is provided with pilot hole, is welded with nut on the pilot hole.Perhaps the other end of supporting element is provided with the flange hole, and flange has been attacked screw thread in the hole.
The utility model is connected as one cylinder and main casing by the supporting element more than three; flange is set to improve rigidity and to strengthen intensity by edge at supporting element; resistance welding or carbon dioxide gas arc welding are adopted in supporting element and main casing welding; fit fully between supporting element and the main casing; thereby improve the rigidity of cylinder, reduce the distortion of cylinder vane slot.When adopting resistance welding, avoided perforate on main casing, therefore reduced the leakage probability of compressor.
The utility model has improved the cylinder of compressor rigidity, has reduced the welding of cylinder and main casing and has leaked, and has improved the efficient and the quality of compressor, has reduced the compressor manufacture cost simultaneously.
