Abstract
The invention discloses mounting components and a dismounting method of a large-sized slewing bearing and solves the problem of maintenance and replacement of the central slewing bearing. The technical scheme is as follows: the mounting components of the large-sized slewing bearing comprise the slewing bearing, an outer ring of the slewing bearing, an inner ring of the slewing bearing, an upper slewing structure and a lower fixing structure, wherein the outer ring of the slewing bearing is fixed on the upper slewing structure through bolts and the slewing bearing is fixed on the upper part of the inner ring of the slewing bearing through screws. When the bolts between the outer ring of the slew bearing and the upper slewing structure are dismounted, the outer ring of the slewing bearing automatically falls off on the lower fixing structure and the slewing bearing is exposed.
Description
Technical field
The present invention relates to the parts in large-scale marine full-rotary crane, relate in particular to mounting assembly and the method for dismounting of huge revolving bearing.
Background technique
In the full-rotary crane of large-scale Shanghai, can equip a kind of important parts: floating bearing.Floating bearing is a kind of large size bearing that can bear combined load, can bear simultaneously larger axially, radial load and tilting moment.Floating bearing is generally with mounting hole, internal gear or external gear, oilhole and seal arrangement, thereby can make host design compact structure, guides easyly, safeguards easily.Floating bearing has Non-tooth type, the four-point contact ball of external tooth type and internal gear type, double-row angular contact formula ball bearing crossed cylindrical roller bearing, four series of crossed-circle taper roller bearing and three-row cylinder roller composite bearing, wherein four-point contact ball has higher dead load ability, crossed cylindrical roller has higher dynamic load ability, the pre-interference of crossed-circle taper roller bearing can make bearing have larger rigidity of support and rotating accuracy, three-row cylinder roller combination bearing is because bearing height is guided in the raising of bearing capacity into, various strength is born by different raceways respectively, so under same stressing conditions, its bearing diameter can dwindle greatly, thereby have that to make the compacter feature of main frame be a kind of floating bearing of high bearing capacity.Floating bearing is widely used on the huge revolving device of the equipment such as Hoisting Machinery, mining machinery, building machinery, harbour machinery, boats and ships facility and high-precision radar machinery and missile launcher.Also can design according to user's specific requirement, develop, produce various special construction floating bearings simultaneously.
Because center steering axle is arranged on bearing inside, if floating bearing damages, be difficult to it safeguard and change.
Summary of the invention
The object of the invention is to address the above problem, a kind of mounting assembly and method for dismounting of huge revolving bearing is provided, solved the maintenance of center steering bearing and the problem of replacing.
Technological scheme of the present invention is: the present invention has disclosed a kind of mounting assembly of huge revolving bearing, comprise floating bearing, floating bearing outer ring, floating bearing inner ring, top revolving structure and bottom fixed structure, floating bearing outer ring is bolted on the revolving structure of top, and floating bearing is fixed by screws in the top of floating bearing inner ring.
According to an embodiment of the mounting assembly of huge revolving bearing of the present invention, the bolt between floating bearing outer ring and top revolving structure is detachable.
According to an embodiment of the mounting assembly of huge revolving bearing of the present invention, after the bolt between floating bearing outer ring and top revolving structure is removed, floating bearing outer ring Automatic-falling, on the fixed structure of bottom, exposes floating bearing.
The present invention has also disclosed a kind of method for dismounting of huge revolving bearing, huge revolving bearing comprises floating bearing, floating bearing outer ring, floating bearing inner ring, top revolving structure and bottom fixed structure, floating bearing outer ring is bolted on the revolving structure of top, floating bearing is fixed by screws in the top of floating bearing inner ring, it is characterized in that, described method for dismounting comprises:
Remove the fixing bolt between floating bearing outer ring and top revolving structure;
Floating bearing outer ring Automatic-falling, on the fixed structure of bottom, exposes floating bearing.
According to an embodiment of the method for dismounting of huge revolving bearing of the present invention, the bolt between floating bearing outer ring and top revolving structure is detachable.
The present invention contrasts prior art following beneficial effect: the solution of the present invention is after bolt between floating bearing outer ring and top revolving structure is removed, floating bearing outer ring Automatic-falling on the fixed structure of bottom, thereby expose floating bearing.Compared to prior art, be of the present inventionly skillfully constructed, method is simple, simple in structurely understand, make simply and easy to operate, and be applicable to most of great type isolated pillar cranes.
