Abstract
The utility model belongs to the technical field of refrigeration compressors of refrigerators, and particularly relates to a refrigeration compressor. The refrigeration compressor comprises a machine body. The refrigeration compressor is characterized in that the machine body is mainly composed of a main shaft, a motor rotor, a motor stator, a swash plate, a piston, a cylinder body, half balls and a valve plate component; the motor rotor and the motor stator are arranged at one end of the main shaft, and the swash plate is arranged at the other end of the main shaft; the piston is arranged in the cylinder body and is connected with the swash plate through the half balls, and one side of the piston is provided with the valve plate component for air suction and exhaust. When the compressor works, the main shaft drives the swash plate to rotate, and the half balls at the two sides of the swash plate drive the piston to move along a hole of the cylinder body in a reciprocating mode. In the process, force acted on the swash plate by the piston directly acts on a flange seat through an end face bearing, so that vibration of the compressor is reduced, and noise is reduced.
Description
Technical field
The invention belongs to refrigerating compressor for refrigerator technical field, specifically relate to a kind of refrigeration compressor; It is mainly used on car refrigerator.

The compressor of conventional refrigerator is generally crankshaft connecting rod type structure, and its rotor is fixed on bent axle, and bent axle is connected with piston by connecting rod; In the time of electric machine rotation, bent axle drives piston to move reciprocatingly in the hole of cylinder body by connecting rod.The shortcoming of this compressor mainly contains the following aspects: 1, in the time of compressor operating, piston acts on the bent axle direction of power and the center line of bent axle by connecting rod are vertical, and the rigidity of bent axle is poor, thereby cause vibration of compressor large, and then cause that noise is larger; 2, the moving element such as piston, connecting rod of this type of compressor is all to adopt cast iron quality, causes movement inertia larger, and then causes that compressor noise is large and energy consumption is high; What 3, the housing of compressor, cylinder body adopted is iron and steel material quality, and this can cause the overall weight of compressor to increase.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of refrigeration compressor is provided; This compressor is dark tool practicability with feature simple in structure, that noise is little and energy consumption is low.
In order to achieve the above object, a kind of refrigeration compressor of the present invention, comprises a body, and described body is mainly by main shaft, rotor, motor stator, swash plate, piston, cylinder body, hemisphere and valve board assembly; Described rotor, motor stator are installed in one end of main shaft, and swash plate is installed in the other end of main shaft; And described piston is located in cylinder body, and be connected with swash plate by hemisphere, one side of this piston is provided with for air-breathing and valve board assembly exhaust.
Preferably, described swash plate two ends are separately installed with end face bearing, and spring bearing (also can change anti-wear sleeve) is installed at the middle part of main shaft.
As the further improvement of such scheme, described spring bearing is fixed on the flange seat of being located at body.
Preferably, described piston (piston can be, can be also multiple) and valve board assembly are located at a side of swash plate.
Preferably, described swash plate and piston are silumin matrix structure, and this not only can increase wear resistance, but also can weight reduction.
Preferably, the two ends, left and right of described body are respectively equipped with motor casing and back cover.
As the further improvement of such scheme, described motor casing is connected by the mode of welding with back cover.
Preferably, described motor casing is provided with inlet hole, is provided with air outlet hole on back cover.
Preferably, the end of described motor casing is provided with tenminal block.
In the time of compressor operating, main shaft drives swash plate to rotate, and drives piston along moving reciprocatingly in the hole of cylinder body by the hemisphere of swash plate both sides.In this process, piston action directly acts on flange seat by end face bearing in the power of swash plate, thereby the vibration of compressor is reduced, and then makes reducing noise.
Piston, swash plate all adopt silumin material, and it has reduced energy consumption and the noise of compressor in ensureing usability.Meanwhile, motor casing and back cover also adopt aluminum alloy material, thereby have reduced the weight of compressor.
