Abstract
The utility model discloses a piston skirt. A cooling oil cavity, a return oil hole, an oil ring groove and a piston hole are arranged on the piston skirt. The diameter phi of the return oil hole is 20mm, and the chamfer R of the cooling oil cavity is 11mm. At present, high strength and low temperature expansion materials are used on a piston with the structural type, thereby enabling cost to be lower and being capable of keeping working under severe working conditions of heavy oil burning, high explosive pressure and the like.
Description
Technical field
The utility model relates to a kind of piston skirt.
Background technique
In the existing technology, the oil ring groove on the piston skirt is too concentrated, excesssive gap, and cause piston skirt precision is not enough.
Summary of the invention
The purpose of the utility model provides a kind of piston skirt.
The utility model for realizing the technological scheme that above-mentioned purpose adopted is: a kind of piston skirt, said piston skirt are provided with cooling oil pocket, spill port, oil ring groove and piston hole, and said spill port diameter of phi is 20mm, and said cooling oil pocket chamfering R is 11mm.
Said piston hole diameter of phi is 229mm.
A kind of piston 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 a kind of piston skirt of the utility model.
Embodiment
As shown in Figure 1, the utility model piston 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 11mm,, spill port 2 diameter of phi are 20mm, piston hole 4 diameter of phi are 229mm.
Claims (2)
1. piston skirt is characterized in that: said piston skirt is provided with cooling oil pocket, spill port, oil ring groove and piston hole, and said spill port diameter of phi is 20mm, and said cooling oil pocket chamfering R is 11mm.
