Abstract
The utility model discloses a steel top iron skirt piston, which comprises a piston top and a piston skirt. The piston top is connected to the piston skirt through a stud. A first air ring, a second air ring and a distortion ring are arranged on the piston top. A combined oil ring is arranged on the piston skirt. At present, high strength and low temperature expansion materials are used on the steel top iron skirt piston with the structural type, and the cylinder diameter of the like piston structure is varied from 160mm to 400mm. and the piston can replace a combined piston, 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 steel head iron skirt piston.
Background technique
In the existing technology, the steel head iron skirt piston 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.
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; Said piston head is provided with top compression ring, second road compression ring and the twist type ring, and said piston skirt is provided with combined oil ring.
Said double-screw bolt is fixedly connected piston head and piston skirt through nut.
Be provided with elastic sleeve between the top of said bolt and piston skirt.
Be provided with the O RunddichtringO between said piston head and the piston skirt.
A kind of steel head iron skirt piston 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.
