Abstract
The invention relates to a wear-resistant cylinder. The inner wall of a cylinder body is coated with a smooth wear-resistant layer; the wear-resistant layer covers on the whole circumference surface of the inner wall of the cylinder; and the wear-resistant layer is a metallic coating or a non-metallic coating, and can improve the wear resistance of the inner wall of the cylinder body. The wear-resistant cylinder is applied to various power machines.
Description
Technical field
The present invention relates to a kind of dynamic power machine, especially the cylinder of dynamic power machine belongs to the machinery field.
Background technique
Dynamic power machines such as diesel engine, petrol engine, pile driver are to utilize the energy of fuel oil blast to promote reciprocating motion of the pistons generation power, carry out work, satisfy people's needs.But, because the piston ring on the piston is in the to-and-fro motion of the cylinder midium or long term cylinder block of will inevitably wearing and tearing, especially in the more abominable dynamic power machine of operating conditions, for example, pile driver is to utilize piston motion to carry out impact pile driving, and it has simple in structure, and is easy to use, do not need the outside that advantages such as the energy are provided, thereby in foundation stabilization construction, brought into play important function.But, because the lubricating condition of pile driver is relatively poor, and piston ring prolonged and repeated kinetic friction in cylinder, make cylinder inner wall produce wearing and tearing, especially the inner wall abrasion of cast iron cylinder is serious, influences the performance of pile driver.Though in the prior art by inlayed the wear problem that cylinder liner solves cylinder at blast area and following position.But for the position of not inlaying cylinder liner, its wear problem still exists.Once had the people to slow down its wearing and tearing by the hardness that improves cylinder in the prior art, still, along with the increase of hardness, cylinder improves fracture easily because of fragility.The somebody slows down its wearing and tearing by the length of intensifying cylinder cover, still, along with the increase of cylinder liner length, for keeping original intensity, will inevitably increase the thickness of cylinder block.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of simple in structure, easy to process, wear resistance is good, the wear-resistant cylinder that intensity is high.
For realizing above goal of the invention, the present invention by the following technical solutions:
A kind of wear-resistant cylinder is characterized in that scribbling smooth wearing layer at the inwall of cylinder block.
As a kind of example preferably, described wearing layer is covered on the whole circumference face of cylinder inner wall.
As another kind example preferably, described wearing layer is a metallic coating.
As another kind example preferably, described wearing layer is a nonmetallic coating.
As another kind example preferably, described wearing layer is the crome metal coating.
As another kind example preferably, described wearing layer is a ceramic coating.
After adopting the technical program, under the situation that material alterations does not take place for the weight and the interior tissue of cylinder block, the wear resistance of inboard wall of cylinder block is greatly improved.
Description of drawings
Accompanying drawing 1 is the structural representation of wear-resistant cylinder.
Among the figure, 1-cylinder block, 2-wearing layer.
Embodiment
In the embodiment shown in fig. 1, wear-resistant cylinder comprises cylinder block 1 and wearing layer 2, and wearing layer 2 is positioned at the inwall of cylinder block 1, is covered on the whole circumference face of cylinder block 1 inwall.Wearing layer 2 is metallic coatings, and such as stainless steel coating, chrome coating etc., perhaps wearing layer 2 is nonmetallic coatings, such as ceramic coating etc.The appearance circumferential surface of wearing layer 2, promptly the junction plane place with piston ring is smooth working surface, helps the to-and-fro motion of piston ring.Wearing layer 2 places by modes such as sprayings on the whole circumference face of cylinder block 1 inwall, then, improves the degree of finish of the appearance circumferential surface of wearing layer 2 by technologies such as grindings.After adopting the technical program, in the weight of cylinder block 1 with organize under the situation that material alterations does not take place, the wear resistance of inboard wall of cylinder block is greatly improved.
The processing method of wearing layer 2 and cylinder liner of the prior art, the technique effect that is obtained are all different.The thickness of wearing layer 2 is generally less, such as the 0.2-0.8 millimeter, except the wear resistance that increases cylinder block 1 inwall, can not produce substantial influence to the intensity of cylinder block 1.But because the thickness of cylinder liner is bigger, especially cylinder liner is inlayed in the part, and then the intensity to cylinder block 1 can produce substantial influence, and because the material of cylinder liner and cylinder block is different, thereby also can produce the difference of thermal expansion.
The technical program is particularly useful for the more abominable motive power machine equipments such as pile driver of working condition.
