Description
Technical field
The utility model relates to a kind of vibratory roller, specifically refers to single vibratory road roller Wheel structure.
Background technology
Road roller is a kind of compacting construction machinery taking special steel wheel or racing slick as apparatus for work, be widely used in the compacting operation to native stone embankment and paving material such as highway construction, harbour, airport, mine dam, urban construction, its effect is the compactness that increases work plane, thereby improve structural strength and the rigidity of work plane, strengthen impermeabilisation ability and resistance to weather, reduce or eliminate depression, finally reaching the object that improves engineering supporting capacity, increases the service life, reduces maintenance cost.Because the operating mode of compacting operation varies, compacting machinary series and description are various, it simply can be divided into road roller, rammer compacter and trash compactor etc.Road roller is divided into again self-propelled, hand held and drags formula, and rammer compacter (equipment is for dull and stereotyped) is divided into again impact plate compactor and vibratory plate compactor etc.
In conjunction with the concrete condition of Chinese road roller technology and production development, road roller can be divided into several large series such as quiet stone roller smooth-wheeled roller, single vibratory road roller, double-steel wheeled vibratory roller, combination roller, rubber-tyred roller, light-duty road roller and other extraordinary road rollers.In the use procedure of single vibratory road roller, because rotating shaft meeting produces a large amount of heat energy, and then cause rotating shaft self-temperature to raise and generation deformation, make can not meet for the reserved gap of rotating shaft the deformation quantity of rotating shaft itself, cause rotating shaft to be rotated dumb, affect the process efficiency of road roller.
Utility model content
The purpose of this utility model is to provide single vibratory road roller Wheel structure, expands and affects operating efficiency after avoiding rotating shaft to work long hours because being heated, and improves the application life of shaft vibration wheel.
The purpose of this utility model is achieved through the following technical solutions:
Single vibratory road roller Wheel structure, involving vibrations wheel body and central axis, one end of central axis is run through and is vibrated the end of wheel body and rotation and be arranged on the other end of central axis and the output of drive motors on vibration wheel body inwall and be connected, on described vibration wheel body, supporting base is installed, on supporting base, support inner ring and support outer ring along being axially disposed with of central axis, on support inner ring, have groove, on groove inwall, have blind hole, in blind hole, rotate and be provided with roller bearing, roller bearing contacts with central axis, junction at roller bearing and groove inwall is provided with floating sleeve, roller bearing is arranged in floating sleeve, between floating sleeve and blind hole inwall, be connected by spring.When the utility model work, drive motors drives central axis to rotate, central axis rotates and is arranged on supporting base, roller bearing contacts with central axis, in the time that the operating temperature of central axis raises, the radial expansion volume of central axis is large, in the method that supports preset clearance on outer ring be not enough to the to make corrections swell increment of central axis, be easy to cause supporting base impaired, reduce its application life, on support inner ring, offer groove, groove two ends are provided with blind hole, blind hole is connected with floating sleeve by spring, roller bearing rotates and is arranged in floating sleeve, floating sleeve can make roller bearing realize displacement radially, by size or the direction of roller bearing acceptor center axle radial stresses, floating sleeve carries out movement in the same way, the compressed radial stresses buffering that central axis can be produced of spring, spring is replied and roller bearing can be resetted, realize the automatic adjusting of central axis in the time being heated generation volumetric change with this, avoid supporting base to cause larger damage, and then extend application life of the present utility model.
