Abstract
The utility model discloses a piston structure, which comprises a piston top and a piston skirt. The piston top and the piston skirt are fixedly connected through a connecting stud and a pin, the gap between the piston top and the piston skirt ranges from 0.04mm to 0.08mm. At present, materials with high strength and lower temperature expansion are used for the piston structure which has variable cylinder diameters ranging from 160mm to 400mm. The piston structure is capable of replacing a combined piston, enabling cost to be cheaper and continuously working under severe working conditions of heavy oil burning, high blasting pressure and the like.
Description
Technical field
The utility model relates to a kind of piston structure.
Background technique
In the existing technology, piston structure is provided with a plurality of nuts, bolt arrangement, causes this kind piston structure complicacy, and cost is higher, and it is bigger to assemble preceding slit, does not meet matching requirements.
Summary of the invention
The purpose of the utility model provides a kind of piston structure.
The utility model for realizing the technological scheme that above-mentioned purpose adopted is: a kind of piston structure; Comprise piston head and piston skirt; Said piston head is fixedly connected with pin through being connected double-screw bolt with piston skirt, and the slit is 0.04-0.08mm between said piston head and the piston skirt.
Said connection double-screw bolt is fixedly connected piston head and piston skirt through nut.
Be provided with elastic sleeve between the top of said connection double-screw bolt and piston skirt.
Said piston head and piston skirt joint are provided with seal ring.
A kind of 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 piston structure structural representation of the utility model.
Embodiment
