Translational rotor compressor

Abstract

The invention relates to a translational rotor compressor, which comprises a rotor (1), a cylinder (2), a blade (3), a rotary column (4) and an end cover, wherein the rotor (1) is provided with a cylindrical outer surface; the cylinder (2) is provided with an circular inner-hole surface; the rotary column (4) is provided with a cylindrical outer surface; the rotor (1) is biased inside the cylinder (2); and the outer surface of the rotor (1) is matched with the inner-hole surface of the cylinder (2) by means of tangent contact. The translational rotor compressor is characterized in that the rotor (1) is limited by a translational mechanism to perform translational rotation; a cylindrical hole (3b) is arranged on the cylinder (2); the outer end of the blade (3) is made into the shape of a cylindrical head and is hinged and matched with the cylindrical hole (3b); a circular groove (5) is arranged on the rotor (1); the rotary column (4) is arranged inside the circular groove (5) and is matched with the circular groove (5) in a sliding way; a flat chute (6) is arranged on the rotary column (4); and the blade (3) is inserted into the chute (6) and is matched with the chute (6) in a sliding way. Because the rotor (1) performs translational rotation, the kinematic velocity of the rotor (1) relative to the cylinder (2) and the end cover is low, thereby the translational rotor compressor is favorable for reducing the friction and the abrasion and has good equilibrium.

Description

technical field [0001] The present invention relates to a compressor, in particular to a rotary compressor, more specifically to a translational rotary compressor. Background technique [0002] Compressor is the key equipment of various gas compression equipment, and has a very wide range of applications in the fields of air compression, refrigeration and air conditioning. Among all kinds of compressors, there is a swing rotor compressor which is very distinctive. This compressor has a rotor, a cylinder, a vane, a rotating column and two end covers; the rotor has a cylindrical outer surface, The cylinder has a circular hole-shaped inner surface, the blade is flat, and the rotating column has a cylindrical outer surface; the rotor is offset in the cylinder, and the axis of the rotor is parallel to the axis of the parallel cylinder, and the two axes The distance is the so-called eccentricity. The axis of the rotor rotates around the axis of the cylinder, and the outer surface...

AI Technical Summary

Problems solved by technology

The advantage of the above swing rotor compressor is that the structure is very simple and reliable, especially the fast connection structure between the blade and the rotor, so the friction loss and leakage loss of the compressor can be effectively eliminated; however, the traditional swing rotor There are also obvious defects in the traditional compressor. For example, the rotor adopts the working mode of swing motion. On the one hand, it is difficult to remove the inertial force of the swing motion, which increases the difficulty of dynamic balance of the compressor; As a result, there is a relatively large relative motion speed between the rotor and the cylinder, and between the rotor and the end cover, which increases the friction and wear of the compressor
