Abstract
The utility model discloses a piston structure of a steel head iron skirt, comprising a piston top and a piston skirt, which are connected through a stud. The piston is made from materials with high strength and low temperature expansion, and the cylinder diameter of the piston structure is within the range of 160-400mm. The piston structure of a steel head iron skirt is advantageous in that the piston can replace a combination piston, reducing cost; continuous work can be achieved under working conditions of heavy oil burning and high detonation pressure.
Description
Technical field
The utility model relates to a kind of steel head iron skirt piston structure.
Background technique
In the existing technology, the steel head iron skirt piston structure is provided with a plurality of nuts, bolt arrangement, causes this kind piston structure complicacy, and cost is higher.
Summary of the invention
The purpose of the utility model provides a kind of steel head iron skirt piston structure.
The utility model for realizing the technological scheme that above-mentioned purpose adopted is: a kind of piston head and piston skirt of comprising, said piston head is connected through double-screw bolt with piston skirt.
Be connected with pin between said piston head and the piston skirt.
Be provided with elastic sleeve between the top of said double-screw bolt and piston skirt.
A kind of steel head iron skirt piston structure of the utility model; The material that present high tenacity, low temperature expand has been used for this structural type piston; At present this type of piston structure does not wait from the 160-400mm cylinder diameter, and this kind piston can the alternative combinations 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 a kind of steel head iron skirt piston structure of the utility model structural representation.
Embodiment
As shown in Figure 1, the utility model steel head iron skirt piston structure comprises piston head 1, piston skirt 2, O type ball sealer 3, double-screw bolt 4, spring housing 5; Piston head 1 is connected through double-screw bolt 4 with piston skirt 2, is connected with pin 6 between piston head 1 and the piston skirt 2, is provided with elastic sleeve 5 between the top of double-screw bolt 4 and piston skirt 2; Be provided with bolt in the elastic sleeve, fixing through nut 7,3, when nut is screwed into; Should be coated with an amount of molybdenum disulfide oil lubricating fat on helical thread portion and the nut seat, nut wants the diagonal angle to divide secondary to tighten equably, and screw-down torque is respectively 50Nm and 95Nm; After tightening for the second time; To nut pine successively be tightened by regulation moment 95Nm to can freely turning state more diagonally successively. and do once to review, on stud head, do marked then with red paint.
