Abstract

The utility model provides a piston used on an air compressor, belonging to the technical field of machinery. The piston used on the air compressor solves the problems of poor lubricating effect and short service life in the current piston of the air compressor. The piston used on the air compressor comprises a piston body, wherein the middle part of the outer side wall of the piston body is provided with a horizontally-penetrated through hole, the lower part of the outer side wall of the piston body is provided with an annular air drain, and the upper part of the outer side wall of the piston body is provided with a first annular oil groove. The piston used on the air compressor has simple structure, good lubricating effect and long piston body.

Description

A kind of piston that is used on the air compressor
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of piston, particularly a kind of piston that is used on the air compressor.
Background technique
Existing air compressor piston, in order to solve in the pistons work process generation of faults such as embracing cylinder, scuffing of cylinder bore, the structure of a concave point of hiding that has been employed in skirt section roll extrusion below the piston head annular groove; Make piston head ability storing lubricating oil; Improve the lubricating condition between piston and cylinder, dwindle the matching gap of engine piston and cylinder, reduced noise; Avoid motor because of the power loss that following qi of chong channel ascending adversely causes, improved engine power performance and operational safety.Its lubricating system has two kinds, and a kind of is splash lubrication, promptly is stored in when the interior lubricant oil of concave point is rotated by bent axle from crankcase, to be splashed on the cylinder inner wall, flow in the concave point after being scraped by scraper ring again; The 2nd, oil injecting lubricating, promptly lubricant oil gets in the gudgeon pin bearing that connects piston head and piston rod through the piston rod inner passage, overflows from the gudgeon pin bearing end then, is scraped by scraper ring to flow in the concave point again, and unnecessary lubricant oil then flows in the crankcase.These two kinds of lubricating systems all need crankcase to be positioned at the piston bottom, and promptly crankcase must maintain oil, and the lubrication effect of piston crown is lubricated not as the piston skirt; In addition, its internal structure is complicated, and manufacture cost is high; Oil product uses repeatedly; Poor quality, coking in cylinder easily, knot charcoal make piston ring sticking.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, has proposed the piston on the air compressor that is used for of a kind of simple in structure, high lubricating effect, long service life.
The purpose of the utility model can realize through following technical proposal: a kind of piston that is used on the air compressor; Comprise piston body; Described piston body outer side wall middle part offers the through hole of lateral direction penetrating; Described piston body outer side wall bottom offers annular gas tank, it is characterized in that, described piston body outer side wall top offers first annular oil groove.
At the above-mentioned piston on the air compressor that is used for, described piston body outer side wall bottom offers second annular oil groove.
At the above-mentioned piston on the air compressor that is used for, the joint of the notch of described second annular oil groove and piston body outer side wall has chamfering.Offering chamfering can make things convenient for lubricant oil to enter in second annular oil groove.
At the above-mentioned piston on the air compressor that is used for, described through hole is between first annular oil groove and second annular oil groove.
The piston on the air compressor that is used for above-mentioned all offers the oil through that several communicate with piston body inside in described first annular oil groove and second annular oil groove.
At the above-mentioned piston on the air compressor that is used for, described oil through is evenly distributed on respectively in above-mentioned first annular oil groove and second annular oil groove.
Compared with prior art, two annular oil grooves are up and down offered in the through hole of piston on piston body that originally is used on the air compressor, thereby increase piston lubricity in use through in annular oil groove, adding lubricant oil, prolong the working life of piston.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1, piston body; 2, through hole; 3, first annular oil groove; 4, second annular oil groove; 5, annular gas tank; 6, oil through; 7, chamfering.
Embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technological scheme of the utility model is done further to describe, but the utility model is not limited to these embodiments.
As shown in Figure 1, the piston that originally is used on the air compressor comprises piston body 1, offers the through hole 2 of lateral direction penetrating at piston body 1 outer side wall middle part, and through hole 2 is mainly used in the placement piston rod.Offer the annular gas tank 5 and second annular oil groove 4 in piston body 1 outer side wall bottom, annular gas tank 5 is mainly used in the placement seal ring, thereby reaches seal action, places gas leakage and prevents that lubricant oil from leaking.The joint of the notch of second annular oil groove 4 and piston body 1 outer side wall has chamfering 7, offers chamfering 7 and can make things convenient for lubricant oil to enter in second annular oil groove 4.
Offer first annular oil groove 3 on piston body 1 outer side wall top; Wherein through hole 2 is between first annular oil groove 3 and second annular oil groove 4; The oil through 6 that in first annular oil groove 3 and second annular oil groove 4, all offers a plurality of even distributions and communicate with piston body 1 inside, oil through 6 are mainly used in and guarantee unimpeded between oil groove and piston body 1 inside.Through hole 2 places on piston body 1 offer two annular oil grooves up and down, thereby increase piston lubricity in use through in annular oil groove, adding lubricant oil, prolong the working life of piston.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
