Description
Technical field
The invention belongs to the reciprocal compressor technical field, refer in particular to the Reciprocting piston compressor of compressor constrained connecting rod and piston moving linearly.
Background technique
As everyone knows, existing the rotatablely moving of the connecting rod of conventional reciprocating piston compressor also has to-and-fro motion: the major part of connecting rod rotatablely moves as circumference with crank pin on the one hand, and the microcephaly of connecting rod does reciprocating linear motion with piston on the other hand.The above-mentioned working method of connecting rod; The power that has determined connecting rod to affact on the piston is the power of a swing that constantly changes; Will inevitably bring some drawbacks thus: at first be to cause piston that cylinder action is had bigger lateral pressure, the result has increased the friction and wear of compressor; Next is to cause piston that cylinder is produced bigger slamming, and the result causes the noise that compressor is bigger.
Summary of the invention
The present invention provides a kind of linear-guidance restricting reciprocating piston compressor, and purpose is effectively to reduce the lateral pressure of piston to cylinder, effectively slows down the slamming of piston to cylinder simultaneously, thereby reduces the friction and wear of compressor, and reduces its noise.
The objective of the invention is to realize like this:
Linear-guidance restricting reciprocating piston compressor; Comprise housing, cylinder, crank pin, connecting rod, piston and slave connecting rod, cylinder is connected on the housing, and piston is installed in the cylinder; One end of connecting rod is connected with piston; The other end of connecting rod is connected with an end of slave connecting rod, and the other end of slave connecting rod is connected with crank pin, it is characterized in that:
Connecting rod or housing are provided with roller, and housing or connecting rod are provided with the guide rail with described roller rolling contact matching.
Be connected with on above-mentioned connecting rod and the housing roller and guide rail are kept the spring that rolls and contact each other, said spring is extension spring or pressure spring or shell fragment spring.
Above-mentioned guide rail has one or some.
Above-mentioned guide rail and cylinder-bore axis laterally arrange.
Above-mentioned roller has one or several, and said roller is one of roll sleeve, rolling bearing, roller, needle roller, ball or its combination.
Above-mentioned connecting rod is connected, is fastenedly connected with piston hinge or the one manufacturing.
Above-mentioned housing is provided with guide pin bushing, and said guide pin bushing and connecting rod are slidingly matched.
Above-mentioned housing or guide pin bushing or housing and guide pin bushing are provided with seal ring, and said seal ring and connecting rod are sealed and matched.
Linear-guidance restricting reciprocating piston compressor of the present invention, its task driven mode is: at first by crank pin driving auxiliary connecting rod, again by the slave connecting rod drive link, so that reciprocating by the connecting rod driven plunger.Obviously, under the constraint of cylinder, roller, guide rail and spring, the piston of compressor and the motion of connecting rod must be straight line motion, have reduced the lateral pressure and the slamming of piston to cylinder thus, so reduced friction, wearing and tearing and the noise of compressor.
