Embodiment Construction

[0033] Specific embodiments are given below in conjunction with the accompanying drawings to further illustrate how the present invention is realized.

[0034] Such as Figure 5 As shown, the internal structure of the rotary compressor is welded and supported. The compressor casing is a container composed of an upper cover 1, a lower cover 14 and a housing 15. The internal structure of the container includes a stator 2 and a rotor 3 that form a motor; and A rotating shaft 4 is pressed into the center of its rotor 3; the outer side of the eccentric portion 16 formed at the lower end of the rotating shaft 4 is provided with a cylinder 8 for compressing the compression space of the refrigerant gas when the rolling ring in the eccentric portion 16 rotates, and supports the rotating shaft 4 The lower end also supports the upper bearing 7 and the lower bearing 13 of the cylinder 8, and the liquid reservoir 11 connected to the suction port 18 formed on the side of the compression spa...

Abstract

The present invention is internal structure welding and supporting mode for rotary compressor. The internal structure includes stator and rotor with rotation shaft embedded in the center, and the rotation shaft is provided with cylinder, upper and lower bearings to support both rotation shaft and the cylinder. Outside the casing, there are liquid storage and exhaust pipe on the top cover. The said structure is supported via upper bearing and welding to the casing inside the casing, and near the welded points there are slots for absorbing and remitting heat deformation of the main shaft during welding. The present invention can ensure the fit precision, and the slots results in saving in material and raised performance / cost ratio.

Description

technical field [0001] The invention relates to an invention in the aspect of a welding support method of a rotary compressor. Furthermore, on the upper bearing of the rotary compressor, the internal structure welding support method of the rotary compressor is reduced by setting slot holes to reduce the thermal deformation of the main shaft during welding. Background technique [0002] In general, rotary compressors are eccentrically combined with rolling rings in the compression part on the rotating shaft combined with the motor. The rolling rings move linearly in the circular cylinder, suck in the refrigerant, compress it and discharge it. [0003] Traditional rotary compressor structure such as figure 1 As shown, it is composed of the following structure: the stator 103 and the rotor 102 of the motor are installed inside the casing A that is provided with a suction port 109a and an output pipe 118 and filled with a certain amount of oil; and is pressed into the center of...
