Abstract
The utility model relates to a piston with lubricating oil grooves, which comprises a piston body and lubricating oil grooves. A plurality of lubricating oil grooves are provided and are uniformly arranged on an outer circumference of the piston body. According to the piston with the lubricating oil grooves, the outer circumference of the piston body is provided with the plurality of lubricating oil grooves. The lubricating oil is brought into the lubricating oil grooves in each motion period. The lubricating oil can lubricate an external surface of the piston body, and can bring the heat which is generated in piston body friction, thereby preventing a burnout phenomenon. The piston with the lubricating oil grooves has the following advantages: simple structure, high practicability and low manufacturing cost.
Description
Technical field
The utility model relates to a kind of piston, refers to the piston of the band oil groove that a kind of greasy property is good especially, belongs to the hydraulic equipment technical field.
Background technique
Along with science and technology development, piston is widely used in the various engineering equipment more, and common piston comprises piston only; The set inside of said piston only has piston cavity, and said piston cavity is used for installing piston rod; Said piston only in the course of the work, its outer surface contacts with the inner surface of container that holds piston only, and does relative movement; The piston of this structure easily in the course of the work; Form the calcination phenomenon, reason is exactly that lubricant oil is following about gravity, always down builds up; Can cause the top of piston because lack lubricant oil; Can not in time be taken away by fricative heat, and formed calcination, influenced the performance and the working life of piston at the upper face of piston.
The model utility content
The utility model purpose is the piston that the good band oil groove of a kind of greasy property is provided for the deficiency that overcomes existing technology.
For achieving the above object, the technological scheme that the utility model adopts is: a kind of piston with oil groove comprises piston only, oil groove; Said oil groove has a plurality of; Be arranged on equably on the excircle of piston only.
Preferably, said oil groove has 3.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The piston of the band oil groove of the utility model; The excircle of said piston only is provided with many oil grooves; All can bring lubricant oil in each cycle of motion in the said oil groove; These lubricant oil are the outer surface of Castor Oil piston only both, can take away the fricative heat of piston only again, can prevent the generation of calcination phenomenon; This programme is simple in structure, practical, low cost of manufacture.
Description of drawings
Below in conjunction with accompanying drawing the utility model technological scheme is described further:
Accompanying drawing 1 is the stereogram of piston of the band oil groove of the utility model;
Accompanying drawing 2 is the sectional view of piston of the band oil groove of the utility model;
Wherein: 1, piston only; 2, oil groove.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
The described a kind of piston with oil groove of the utility model comprises piston only 1, oil groove 2; Said oil groove 2 has a plurality of; Be arranged on equably on the excircle of piston only 1.
The described a kind of piston with oil groove of the utility model shown in accompanying drawing 1-2, said oil groove 2 has 3, is arranged on equably on the excircle of piston only 1.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The piston of the band oil groove of the utility model; The excircle of said piston only is provided with many oil grooves; All can bring lubricant oil in each cycle of motion in the said oil groove; These lubricant oil are the outer surface of Castor Oil piston only both, can take away the fricative heat of piston only again, can prevent the generation of calcination phenomenon; This programme is simple in structure, practical, low cost of manufacture.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation, all employing equivalents or equivalence replacement and the technological scheme that forms all drops within the utility model rights protection scope.
Claims (2)
1. the piston with oil groove comprises piston only, oil groove; It is characterized in that: said oil groove has a plurality of; Be arranged on equably on the excircle of piston only.
2. the piston of band oil groove according to claim 1; It is characterized in that: said oil groove has 3.
