Abstract
The utility model discloses an installation assembly and a disassembling method of a large-sized rotary bearing, which solve the problem for maintaining and replacing a central rotary bearing. According to the technical scheme, the installation assembly comprises the rotary bearing, a rotary bearing outer ring, a rotary bearing inner ring, an upper rotary structure and a lower fixed structure, wherein the rotary bearing outer ring is fixed on the upper rotary structure through a bolt, and the rotary bearing is fixed on the upper part of the rotary bearing inner ring through a screw. After the bolt between the rotary bearing outer ring and the upper rotary structure is dismounted, the rotary bearing outer ring is automatically separated from the upper rotary structure and falls on the lower fixed structure, and the rotary bearing is exposed.
Description
Technical field
The utility model relates to the parts in large-scale marine full-rotary crane, relates in particular to the mounting assembly 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.
Model utility content
The purpose of this utility model is to address the above problem, and a kind of mounting assembly of huge revolving bearing is provided, and has solved the maintenance of center steering bearing and the problem of replacing.
The technical solution of the utility model is: the utility model 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 utility model, 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 utility model, 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 utility model contrast prior art has following beneficial effect: scheme of the present utility model 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 utility modelly 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.
Brief description of the drawings
The structural drawing of the mounting assembly of floating bearing when Fig. 1 shows normal work.
The location diagram of bearing enclose when Fig. 2 shows maintenance.
Embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
The rigging position of the center steering bearing enclose of the mounting assembly that Fig. 1 shows huge revolving bearing of the present utility model in the time of normal work, the position relationship of the center steering bearing enclose of the mounting assembly that Fig. 2 shows huge revolving bearing in the time of maintenance.Please be simultaneously referring to Fig. 1 and Fig. 2, the mounting assembly of the huge revolving bearing of the present embodiment comprises floating bearing 1, floating bearing outer ring 2, floating bearing inner ring 3, top revolving structure 4 and bottom fixed structure 5, floating bearing outer ring 2 is bolted on top revolving structure 4, and floating bearing 1 is fixed by screws in the top of floating bearing inner ring 3.
Bolt between floating bearing outer ring 2 and top revolving structure 4 is detachable, and after the bolt between floating bearing outer ring 2 and top revolving structure 4 is removed, floating bearing outer ring 2 Automatic-fallings, on bottom fixed structure 5, expose floating bearing 1.
In the time of dismounting, first remove the detachable fixing bolt between floating bearing outer ring 2 and top revolving structure 4, floating bearing outer ring 2 Automatic-fallings, on bottom fixed structure 5, expose floating bearing 1 afterwards.
Above-described embodiment is available to those of ordinary skill in the art and realizes and use of the present utility model; those of ordinary skill in the art can be in the situation that not departing from invention thought of the present utility model; above-described embodiment is made to various modifications or variation; thereby protection domain of the present utility model do not limit by above-described embodiment, and it should be the maximum magnitude that meets the inventive features that claims mention.
