Problems solved by technology

The above-mentioned working method of the connecting rod determines that the force acting on the piston by the connecting rod is a constantly changing swinging force, which will inevitably bring some disadvantages: first, it will cause the piston to have a large lateral pressure on the cylinder, As a result, the friction and wear of the compressor are increased; secondly, it causes the piston to produce a greater flapping motion against the cylinder, which results in a greater noise of the compressor

Embodiment 1

[0020] Example 1, see figure 1 :

[0021] Linear guide constrained reciprocating piston compressor, including: housing 1, cylinder 2, crank pin 3, connecting rod 4, piston 5 and auxiliary connecting rod 6, the cylinder 2 is connected to the housing 1, and the piston 5 is installed In the cylinder 2 and slidingly fit with it, one end of the connecting rod 4 is connected with the piston 5, the other end of the connecting rod 4 is connected with one end of the auxiliary connecting rod 6, and the other end of the auxiliary connecting rod 6 is connected with the crank pin 3 Connected and rotated with it, the connecting rod 4 is composed of a shaft and a rod frame. The frame can be in the shape of a ring frame, hook or plate; in particular, it should be pointed out that the above-mentioned connecting rod 4 can be hinged with the piston 5 through a piston pin, or can be fastened with the piston 5 through screws or rivets, or even It can also be integrally manufactured together with...

Embodiment 2

[0022] Example 2, see figure 1 :

[0023] Labels, names and function inheritance of parts in the figure figure 1 And embodiment 1, the structure of this embodiment is basically the same as embodiment 1, the difference is that: the roller 7 is arranged on the housing 1, and the guide rail 8 is arranged on the connecting rod 4 accordingly.

Embodiment 3

[0024] Example 3, see figure 1 :

[0025] Labels, names and function inheritance of parts in the figure figure 1 And embodiment 1, the structure of this embodiment is basically the same as embodiment 1, and its difference is: this embodiment cancels spring 9, replaces and sets two guide rails 8 and several rollers 7, and wherein roller 7 is still provided with On the connecting rod 4, the guide rail 8 is arranged on the housing 1. It should be noted that more than two guide rails 8 can also be used in this case.

Abstract

The invention relates to a linear-guidance restricting reciprocating piston compressor, belonging to the technical field of the reciprocating compressor. The linear-guidance restricting reciprocatingpiston compressor comprises a shell, an air cylinder, a crank pin, a connecting rod, a piston and an auxiliary connecting rod. The air cylinder is connected with the shell; the piston is arranged in the air cylinder and is matched with the air cylinder in a sliding way; one end of the connecting rod is connected with the piston, and the other end is connected with one end of the auxiliary connecting rod; the other end of the auxiliary connecting rod is connected with the crank pin; the connecting rod or the shell is provided with rolling wheels, guide rails and a spring, wherein the guide rails are matched with the rolling wheels in a rolling contact way, and the spring which compresses the rolling wheels and guide rails. Obviously, under the restriction of the air cylinder, the rolling wheels and the spring, the piston and the connecting rod of the linear-guidance restricting reciprocating piston compressor can move linearly, thus the lateral compressing and the padding to the air cylinder from the piston are decreased, and the friction, the wear and the noise of the linear-guidance restricting reciprocating piston compressor are reduced.

Description

technical field [0001] The invention belongs to the technical field of reciprocating compressors, in particular to a reciprocating piston compressor that constrains a compressor connecting rod and a piston to perform linear motion. Background technique [0002] As we all know, the connecting rod of the traditional reciprocating piston compressor has both rotary motion and reciprocating motion: on the one hand, the big end of the connecting rod makes a circular motion with the crank pin, and on the other hand, the small end of the connecting rod makes a reciprocating linear motion together with the piston. The above-mentioned working method of the connecting rod determines that the force acting on the piston by the connecting rod is a constantly changing swinging force, which will inevitably bring some disadvantages: first, it will cause the piston to have a large lateral pressure on the cylinder, As a result, the friction and wear of the compressor are increased; secondly, i...
