Description
Technical field
The utility model is related to engine cylinder recovery technique field, and in particular to a kind of novel steam cylinder sleeve for repairing
Structure.
Background technology
Engine cylinder for various reasons, can produce the damage such as broken, leak；There is two ways at present, one is to start
Machine is scrapped, relatively costly, wastes serious；Two is that the engine to broken, leak is repaired；To repair it is general using welding or
The method of bonding.During welding, either gas welding, electric welding, because cylinder aperture is limited, soldering appliance enters difficult, enters reluctantly,
Welding quality is affected, further machining is difficult；Using bonding way, one is that bonding agent is difficult to reach the intensity of cylinder
And precision, two is the immersion of the high temperature and long-time water that cylinder is not highly resistant to after bonding, does not reach and repairs cylinder
Purpose.
The patent of Application No. CN01261557.9, discloses the damaged engine cylinder of reparation, and it includes cylinder body and work
Make cylinder sleeve, be characterized in that between cylinder body and work cylinder sleeve and be embedded in fixed cylinder sleeve, fixed cylinder sleeve and cylinder body adopt interference fit, working cylinder
In being placed on fixed cylinder sleeve；Because fixed cylinder sleeve and cylinder body adopt interference fit, and cylinder body, work cylinder sleeve and stationary cylinder are enclosed within work
Heat is produced during work can be expanded, and the stress for causing cylinder body, work cylinder sleeve and fixed cylinder sleeve crosses its breakage of ambassador, reduces cylinder
The service life of body, work cylinder sleeve and fixed cylinder sleeve.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of Novel cylinder noose for repairing
Structure.
The purpose of this utility model is achieved by the following technical programs：
A kind of Novel cylinder nested structure for repairing, including engine cylinder body and cylinder sleeve are provided, it is described to start
Machine cylinder block is internally embedded and is provided with cylinder sleeve, and interference fits are adopted between the engine cylinder body and cylinder sleeve；
The cylinder sleeve includes cylinder sleeve one and cylinder sleeve two, and the cylinder sleeve two is located at the inside of cylinder sleeve one, cylinder sleeve one and cylinder sleeve
The outer wall middle part that interference fit, the cylinder sleeve two is adopted between two is provided with helical groove, and the bottom of the helical groove sets
The sprocket hole one for having and communicating inside cylinder sleeve two, the upper surface of the cylinder sleeve two is provided with the sprocket hole communicated with helical groove
Two.
Further, the cross section of the helical groove is ellipse, circular arc, V-arrangement or U-shaped.
Further, the inner wall surface of the cylinder sleeve two is coated with layers of chrome.
Compared with prior art, the utility model has the advantages that：
（1）Can cause expansion because engine cylinder body and cylinder sleeve are heated in use, therefore this practicality is new
Type can be become engine cylinder body and cylinder sleeve by thermogenetic expansion by being provided with helical groove in the outer wall of cylinder sleeve two
Shape is effectively discharged, so as to effectively release engine cylinder body and cylinder sleeve distortional stress.
（2）The outer wall of the cylinder sleeve two of the present utility model is provided with helical groove, and the lubricants such as lubricating oil, butter are passed through
In the input helical groove of sprocket hole two, when engine cylinder-body produces heat in the course of the work, lubricant can be in helical form
Circulate in groove, while the sprocket hole one that can also pass through the bottom of helical groove is entered inside cylinder sleeve two, play to cylinder
The effect of piston lubrication, reduces the friction of steam-cylinder piston and cylinder sleeve two, improves the mechanical efficiency of steam-cylinder piston.
（3）The utility model simple structure, it is easy to use, cylinder sleeve is alleviated by the helical groove on cylinder two
Weight, while being greatly reduced the cost of cylinder body repair and cylinder sleeve manufacture.

Specific embodiment
The utility model is further described with reference to specific embodiment.Wherein, being for illustration only property of accompanying drawing
Illustrate, expression is only schematic diagram, rather than pictorial diagram, it is impossible to be interpreted as the restriction to this patent；In order to this reality is better described
With new embodiment, accompanying drawing some parts have omission, zoom in or out, and do not represent the size of actual product；To ability
For field technique personnel, some known features and its explanation in accompanying drawing may be omitted and will be understood by.
Embodiment 1
As shown in accompanying drawing 1～4, there is provided a kind of Novel cylinder nested structure for repairing, including the He of engine cylinder body 1
Cylinder sleeve 2, the engine cylinder body 1 is internally embedded and is provided with cylinder sleeve 2, the engine cylinder body 1 and cylinder sleeve 2 it
Between adopt interference fits；
The cylinder sleeve 2 includes cylinder sleeve 1 and cylinder sleeve 24, and the cylinder sleeve 24 is located at the inside of cylinder sleeve 1, the cylinder sleeve
