Problems solved by technology

According to the structure, the rotary compressor also has the following defects: 1. In order to prevent the vanes from breaking away from the grooves on the outer peripheral surface of the piston, the required spring force of the spring is relatively large, and the spring stiffness of the rotary compressor spring is estimated to be Should be controlled above 20Kg/㎜
As a result, a series of problems arise: such as the increased pr

Abstract

The invention provides a rotary-type translation piston compressor, and belongs to the technical field of mechanical engineering, in order to solve the problem that an existing rotary-type compressor is high in elastic stiffness of a spring. The rotary-type translation piston compressor comprises an air cylinder with a piston cavity and a crankshaft with an eccentric part positioned in the piston cavity; an air cylinder blade groove is provided with a blade; a piston is sleeved on the eccentric part; the outer side surface of the eccentric part and the inner side surface of the piston are connected through a rolling bearing component; a bar-shaped concave circular arc groove which is parallel to a piston bus is formed on the outer circumference surface of the piston; the top surface of the blade is a convex circular arc curve surface; the circular arc top of the blade is embedded into the concave circular arc groove of the piston, and the top surface of the blade and the concave circular arc groove surface butt against mutually under the effect of spring force. The rotary-type translation piston compressor is applied to 1-1.5HP air conditioners, and the elastic stiffness of the spring is only required to be controlled to 2-4Kg/mm, or even lower.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering, and relates to a liquid variable displacement machine of a rotary piston, in particular to a rotary translational piston compressor. Background technique [0002] A compressor is a driven fluid machine that raises low pressure gas to high pressure. The air conditioner compressor is the heart of the refrigeration system. Rotary piston air conditioner compressors are widely used in household air conditioners. [0003] There are many relevant documents about rotary piston compressors, such as the rotary piston compressor [application number: 97114554.7; publication number: CN1174297A] recorded in Chinese patent literature. In the background art of this document, conventional rotary piston compressors are described, such as Figure 7 and Figure 8 As shown, a crankshaft 101 having an eccentric portion 102 , a motor 103 driving the crankshaft 101 to rotate, a cylinder 104 , vanes 105...
