Description

Linear orbital ring for linear piston compressor

Technical Field

The utility model relates to a compressor technical field especially relates to a linear piston compressor's linear orbit ring.

Background

A piston compressor is a compressor that pressurizes and delivers gas by means of reciprocating movement of a piston. Belongs to a displacement compressor, also known as a reciprocating piston compressor or a reciprocating compressor. Mainly comprises a working cavity, a transmission component, a machine body and an auxiliary component. The working cavity is directly used for compressing gas and consists of a cylinder, a cylinder sleeve, an air valve, a filler, a piston and a piston rod. The piston is driven by a piston rod to do reciprocating motion in the cylinder, the volumes of working cavities on two sides of the piston are changed in turn, the gas on one side with reduced volume is discharged through an air valve due to increased pressure, the gas on one side with increased volume is sucked through the air valve due to reduced air pressure, a transmission part is used for realizing reciprocating motion and comprises a crankshaft connecting rod, an eccentric sliding block, a swash plate and the like, wherein the crankshaft connecting rod mechanism is most commonly used and comprises a crosshead, a connecting rod, a crankshaft and the like.

The existing piston type compressor has the advantages of complex structure, difficult processing, great difficulty in replacing parts, great friction coefficient during operation and reduced service life of the compressor.

SUMMERY OF THE UTILITY MODEL

In order to solve the defects existing in the prior art, the utility model provides a linear orbit ring of linear piston compressor.

The technical scheme of the utility model is realized like this:

the utility model provides a linear piston compressor's linear track ring, includes the casing and arranges the inside motor of casing in, its characterized in that, the motor pole has on the motor, the last linear shaft that has of motor pole, the cover has linear ring on the linear shaft, inside first supporting part and the second supporting part of having of casing, linear shaft passes through the bearing and installs on first supporting part, linear ring passes through the bearing and installs on the second supporting part, linear shaft, linear ring are between first supporting part and second supporting part, the last piston that has of linear ring.

The utility model discloses a linear piston compressor's linear track ring, the surface of linear axis has and is the track groove that V font symmetry set up end to end, the steel ball groove has on the inner wall of linear ring, the steel ball has been inlayed in the steel ball groove, what the steel ball corresponds arranges in the track groove.

The utility model discloses a linear piston compressor's linear track ring, the steel ball is arranged in half in the steel ball groove, and the other end is arranged in the track groove.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1 to 4, the linear track ring of the linear piston compressor of the present invention includes a housing 10 and a motor 11 disposed inside the housing 10, wherein the motor 11 has a motor rod 12, the motor rod 12 has a linear shaft 13, and the linear shaft 13 is sleeved with a linear ring 14. The housing 10 has a first support 15 and a second support 16 inside, the linear shaft 13 is mounted on the first support 15 by a bearing 17, the linear ring 14 is mounted on the second support 16 by a bearing 17, the linear shaft 13, the linear ring 14 are between the first support 15 and the second support 16, and the linear ring 14 has a piston 18 thereon.

The surface of the linear shaft 13 is provided with V-shaped symmetrically arranged end-to-end rail grooves 19, the inner wall of the linear ring 14 is provided with a steel ball groove 20, steel balls 21 are embedded in the steel ball groove 20, and the steel balls 21 are correspondingly arranged in the rail grooves 19. Half of the steel ball 21 is arranged in the steel ball groove 20, and the other end is arranged in the track groove 19. Through the rotation of motor 11, drive motor pole 12, make motor pole 12 drive linear shaft 13 and rotate, and linear shaft 13 is when rotating, can make steel ball 21 in the track groove 19 on the linear shaft 13 along the track motion of track groove 19 in track groove 19, and the other half of steel ball 21 is then inlayed in the inner wall of linear ring 14, make linear ring 14 also can be along with steel ball 21 motion, thereby make linear ring 14 do reciprocating type's motion, thereby piston 18 works, compressed gas.
