Abstract
The utility model relates to a high speed lubrication engine piston, wherein the piston body comprises an ellipse external circle, the lower end of the skirt section is large, the skirt section is mainly used to stabilize the piston of up and down motion to prevent the piston from swinging, the upper end of the piston body is provided with a first ring groove, a second ring groove and an oil ring groove which are smaller, therefore, the piston can normally work for short time when there is few machine oil of the engine and the piston ring can normally operate in an elastic type, to prevent baffling the elasticity of the piston ring caused by marks, prevent clipping ring, prevent cylinder scuffing, prevent abrasion and prevent friction heat in short time, and improve lubrication and accelerate heat radiation. The upper and lower ends of the first ring groove, the second ring groove and the oil ring groove of the piston body are inclined at the part adjacent to the external basket of the piston ring, therefore, the piston ring can normally work in an elastic type in the ring grooves and move up and down in the tight attachment with the cylinder wall, to prevent baffling the elasticity of the piston ring caused by marks, prevent clipping ring and prevent cylinder scuffing. Part of the skirt section of the piston body is distributed with machine oil holes densely, to completely lubricate the piston of high speed operation, accelerate heat radiation, reduce abrasion, prevent friction heat, prevent cylinder scuffing and improve the normal operation state of the engine.
Description
Technical field
The utility model relates to the improvement technological scheme of piston, is specifically related to a kind of new structure engine piston.
Technical background
Along with development of technology and people to the new product demand, engine performance is required more and more higher, progressively improve development, and also require more superior the performance of piston.And present engine piston structure is all prolonged with former general structure and is had many defectives.At present, there are many defectives in known engine piston structure: the annular groove upper and lower end at an annular groove of piston body, two annular grooves, oil ring groove is too near near the outer basket angular distance of piston ring, the few machine oil of motor turn round the hot operation state in the short time under easily friction cause vestige, vestige cause obstruction piston ring elasticity, easily cause snap ring, scuffing of cylinder bore, influence the motor proper functioning.The oil hole of piston body skirt portion distributes and lacks, cause easily heavy wear, frictional heating, heat radiation slowly, lack of lubrication, influence motor and do not reach optimum efficiency at the state of running up for a long time.
The content of model utility
Under running up, can not reach best lubricating effect in once superior improvement in order to overcome existing engine piston, the utility model provides a kind of high-speed lubrication engine piston, this piston can not only be in engine motor oil proper functioning in a small amount of short time, and can safeguard the operation of piston ring normal elasticity, can prevent at short notice that vestige from causing obstruction piston ring elasticity, snap ring, scuffing of cylinder bore, wearing and tearing, frictional heating, can also increase lubricated and accelerate and dispel the heat.
The purpose of this utility model is to realize like this
Fig. 1 is set to gradient at the annular groove upper and lower end of an annular groove of piston body, two annular grooves, oil ring groove near the outer basket angle of piston ring, make piston ring normal elasticity work and closely operation up and down of cylinder wall in annular groove, prevent that vestige from causing obstruction piston ring elasticity, snap ring, scuffing of cylinder bore, improves motor and normally move working state.
Fig. 2 is covered with oil hole in the setting of piston body skirt portion, makes piston obtain sufficient lubrication, accelerate dispel the heat, to reduce wear, prevent frictional heating, snap ring, scuffing of cylinder bore running up, and the raising motor normally moves working state.
The outer basket of the annular groove upper and lower end of one annular groove of 1 piston body, two annular grooves, oil ring groove angle is set to gradient.
2 piston body skirt portion settings are covered with oil hole.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is an original structure piston A-1 plan view
Fig. 2 is an original structure piston A-2 sectional view
Fig. 3 is the utility model structure piston A-3 plan view
Embodiment
The utility model mainly improves piston only.
A basket angle is set to gradient outside the annular groove upper and lower end of an annular groove (1) of scheming the A-1 piston body, two annular grooves (1), oil ring groove (1).
Be covered with oil hole (2) in the setting of figure A-2 piston body skirt portion.
Claims (1)
1, a kind of high-speed lubrication engine piston comprises body, piston ring and wrist pin, it is characterized in that an annular groove, two annular grooves of piston body, the outer basket of the annular groove upper and lower end angle of oil ring groove are set to gradient, and the setting of piston body skirt portion is covered with oil hole.
