Abstract

The utility model discloses a rotary compressor subassembly, it including: stator, rotor, the pump body, the barrel, the upper cover, the bottom, its technical essential: the end part of the inner side of the cylinder body along the periphery is fixedly connected with a sealing head bottom cover in the reverse direction; the upper cover is also provided with an exhaust pipe and a wiring terminal; the pump body comprises a cylinder, a piston, a crankshaft, a lower bearing and an upper bearing. The reverse stretching can increase the radial tensile stress, so that the inner surface and the outer surface of the material are mutually transferred, the deformation degree of the material can be increased, the material is not easy to wrinkle, and the residual stress is smaller. The improved bottom cover structure has the advantages that the height of the stretching protrusion is the same as that of the reverse stretching edge, the protrusion part of the reverse stretching bottom cover structure is included in the reverse stretching edge, the material consumption is reduced, the size of the bottom cover is reduced, and the height of the bottom cover is reduced.

Description

Rotary compressor assembly

Technical Field

The utility model relates to a compressor technical field, concretely relates to can increase radial tensile stress, reduce high rotary compressor subassembly.

Background

As is well known, a compressor is composed of a stator, a rotor, a pump body, a casing, and the like. The pump body comprises a cylinder, a piston, a crankshaft, a slide block and an upper bearing and a lower bearing, and the working principle is that a motor rotor drives the crankshaft to rotate, and the crankshaft rotates to drive the piston to rotate, so that a refrigerant is continuously compressed, and high-temperature and high-pressure refrigerant gas is discharged. The rotary compressor shell is formed by welding a cylinder body and an end socket-shaped bottom cover; the directly stretched seal head-shaped bottom cover protrudes outwards, the height after being welded with the cylinder is the height of the cylinder, the height of the bottom cover is the sum of the height of the cylinder and the height of the overlapped part, and the bottom cover is higher in overall height and poorer in placement prevention stability at present; the positive tension structure is prone to internal wrinkling.

Disclosure of Invention

An object of the utility model is to provide a can increase radial tensile stress, reduce high rotary compressor subassembly.

In order to achieve the above object, the utility model adopts the following technical scheme:

a rotary compressor assembly comprising: stator, rotor, the pump body, the barrel, the upper cover, the bottom, its characterized in that: the end part of the inner side of the cylinder body along the periphery is fixedly connected with a sealing head bottom cover in the reverse direction; the upper cover is also provided with an exhaust pipe and a wiring terminal; the pump body comprises a cylinder, a piston, a crankshaft, a lower bearing and an upper bearing.

The working principle is that a motor rotor drives a crankshaft to rotate, and the crankshaft rotates to drive a piston to rotate, so that a refrigerant is continuously compressed, and high-temperature and high-pressure refrigerant gas is discharged.

The structure is that a positive stretching bottom cover is changed into a sealing head bottom cover which is fixedly connected with the inner side of the cylinder body along the end part of the periphery in the reverse direction, the bottom end of a hollow spherical structure obtained by primary drawing is reversely pressurized to finish secondary drawing in the direction opposite to the primary stretching, the inner surface of a steel plate is turned into the outer surface, the reverse stretching edge is welded with the cylinder body, the height of the bottom cover is reduced, the volume of the bottom cover is reduced, the placement stability is improved,

has the advantages that:

the reverse stretching can increase the radial tensile stress, so that the inner surface and the outer surface of the material are mutually transferred, the deformation degree of the material can be increased, the material is not easy to wrinkle, the residual stress is smaller, and the hardening degree of the material caused by the reverse stretching structure is lower than that of the forward stretching structure; the improved bottom cover structure has the advantages that the height of the stretching protrusion is the same as that of the reverse stretching edge, the protrusion part of the reverse stretching bottom cover structure is included in the reverse stretching edge, materials are reduced, the size of the bottom cover is reduced, the height of the bottom cover is reduced, the total height of the shell is effectively reduced, and further the total height of the whole machine is reduced.
