Abstract
The utility model discloses a piston skirt of a steel crown iron skirt piston. A cooling oil cavity, an oil return hole, an oil ring groove and a piston hole are arranged on the piston skirt. A chamfer R of the cooling oil cavity is 36mm. The steel crown iron skirt piston adopts materials with high strength and low temperature expansion so that the cost is lower and the steel crown iron skirt piston is capable of continuously working under the working conditions of heavy oil combustion and high detonation pressure and the like.
Description
Technical field
The utility model relates to a kind of piston skirt of steel head iron skirt.
Background technique
In the existing technology, the oil ring groove on the piston skirt of steel head iron skirt is too concentrated, and excesssive gap causes the piston skirt precision of steel head iron skirt not enough.
Summary of the invention
The purpose of the utility model provides a kind of piston skirt of steel head iron skirt.
The utility model for realizing the technological scheme that above-mentioned purpose adopted is: a kind of piston skirt of steel head iron skirt, said piston skirt are provided with cooling oil pocket, spill port, oil ring groove and piston hole, and said cooling oil pocket chamfering R is 36mm.
Said spill port diameter of phi is 24mm.
Said piston hole diameter of phi is 219mm.
The piston skirt of a kind of steel head iron skirt of the utility model, the material that present high tenacity, low temperature expand has been used for this structural type piston, makes cost more cheap, and can be under abominable operating mode such as burning heavy oil, high detonation pressure, continual work.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the structural representation of the piston skirt of a kind of steel head iron skirt of the utility model.
Embodiment
As shown in Figure 1; The piston skirt of the utility model steel head iron skirt, piston skirt are provided with cooling oil pocket 1, spill port 2, an oil ring groove 3 and a piston hole 4, and cooling oil pocket 1 chamfering R is 36mm; Spill port 2 diameter of phi are 24mm, and piston hole 4 diameter of phi are 219mm, and the width of oil ring groove 3 is 10.045-10.07mm.
Claims (3)
