The invention discloses a portable large-tonnage combined-type slewing bearing capable of being demounted and mounted, and belongs to the field of mating parts of lifting devices of cranes. The portable large-tonnage combined-type slewing bearing comprises a double-shaft ring, a double-seat ring and a base, wherein the bearing is internally provided with twelve linear roller paths; the double-shaft ring comprises a first shaft ring and a second shaft ring; the double-seat ring comprises a first seat ring and a second seat ring; four rows of axially symmetrical rolling elements and two rows of radially symmetrical rolling elements of the bearing and the double-seat ring and double-shaft ring of the bearing are integrated into a whole, and connected with the base together by pin connections; and the first seat ring and the second seat ring are in radial connection with the base by a locating pin. A V-shaped hole is formed in the radial direction of the base; the locating pin penetrates through the V-shaped hole, the first seat ring and the second seat ring radially, and is locked by a split pin; and the precise location in the circumferential direction is achieved by the locating pin and the V-shaped hole when the bearing is mounted. The quick mounting and demounting of the bearing are achieved by inserting or removing a connecting pin.
Description
Technical field
The present invention relates to large-tonnage portable dismounting combined type turntable bearing, it belongs to crane lifting matched with devices part field.
Background technique
In recent years, along with the reinforcement of China's infrastructure construction, especially at Large Construction construction projects such as Three Gorges Projects, Qinghai-Tibet Railway, transferring electricity from the west to the east and transfering natural gas from the west to the easts, and under the pulling that develop rapidly of the industry such as electric power, oil, chemical industry, the domestic hoister in large tonnage market demand increases day by day remarkable.Along with the intensification in hoister in large tonnage market, domestic hoist manufacturing enterprise starts to develop hoister in large tonnage one after another, and China has also been invested sight by famous foreign hoist manufacturing enterprise, increases the dynamics of investment to Chinese hoister in large tonnage market.Especially the equipment such as 1000 tons of super large truck cranes, engineering machinery is particularly harsh to the requirement of its supporting turntable bearing, requires to overcome huge axial force, radial force and tilting moment.So the turntable bearing of design has high bearing capacity.Simultaneously due to bulky, the transport before and after using also is urgent problem.
Summary of the invention
In view of the defect that prior art exists, the invention provides large-tonnage portable dismounting combined type turntable bearing, there is high-mechanic, hi-Fix and convenient dismounting performance.
For achieving the above object, the technical solution adopted in the present invention is that this bearing comprises and being made up of twin shaft circle, two-seater circle and base, be provided with 12 linarity raceways in bearing, twin shaft circle comprises the first blowout patche and the second blowout patche, and two-seater circle comprises the first seat ring and the second seat ring; Bearing shaft to four row rolling elements of symmetry, two row rolling elements of radial symmetric, two-seater circle and the twin shaft circle of bearing are integrated, and connected link together with base by pin; First seat ring, the second seat ring carry out radial direction by locating stud and base and are connected.Described base radial direction is provided with V shaped hole, and locating stud, radially across V shaped hole and the first seat ring, the second seat ring, is locked by cotter pin; Realize circumferencial direction when bearing is installed by locating stud and V shaped hole accurately to locate.Described bearing also comprises connecting pin two-seater circle and base linked together and the hydraulic pressure installation be fixed on connecting sheet; Four connecting pins are one group, and hydraulic pressure installation carries out latch and pulls pin; When connecting pin is extracted, base separates with bearing upper part, thus realizes upper and lower two-part separately, and when connecting pin injects pin-and-hole, bearing upper part and base just link together, and start working.
After adopting such scheme, compared with prior art have following beneficial effect: axle is made up of twin shaft circle, two-seater circle and base, bearing has 12 linarity raceways, achieves multidirectional carrying.Four axially all symmetrical row rolling elements are used for bearing great axial force and tilting moment, and two row rolling elements of radial symmetric bear great radial force.Realize circumferencial direction when bearing is installed by locating stud and V shaped hole accurately to locate.By the insertion of connecting pin or extract and realize bearing rapid-assembling and dismounting.

Embodiment
For understanding the structure of large-tonnage portable dismounting combined type turntable bearing in depth, composition graphs 1 to Fig. 3 is described as follows:
Large-tonnage portable dismounting combined type turntable bearing, this bearing comprises and being made up of twin shaft circle, two-seater circle and base 1, is provided with 12 linarity raceways in bearing, and twin shaft circle comprises the first blowout patche 4 and the second blowout patche 5, and two-seater circle comprises the first seat ring 2 and the second seat ring 3; Bearing shaft to four row rolling elements of symmetry, two row rolling elements of radial symmetric, two-seater circle and the twin shaft circle of bearing are integrated, and connected link together with base 1 by pin; First seat ring 2, second seat ring 3 carries out radial direction by locating stud 6 with base 1 and is connected.Described base 1 radial direction is provided with V shaped hole, and locating stud 6, radially across V shaped hole and the first seat ring 2, second seat ring 3, is locked by cotter pin 7; Realize circumferencial direction when bearing is installed by locating stud 6 and V shaped hole accurately to locate.Described bearing also comprises the connecting pin 9 two-seater circle and base linked together and the hydraulic pressure installation be fixed on connecting sheet 8; Four connecting pins are one group, and hydraulic pressure installation carries out latch and pulls pin; When connecting pin 9 is extracted, base 1 separates with bearing upper part, thus realizes upper and lower two-part separately, and when connecting pin 9 injects pin-and-hole, bearing upper part and base just link together, and start working.
The present invention is the multidirectional carrying of super sized type truck crane, combined type turntable bearing, is designed to have high bearing capacity, installs combined type turntable bearing easily.Be made up of twin shaft circle, two-seater circle and base, bearing has 12 linarity raceways, achieves multidirectional carrying.Axial, radial four all symmetrical row rolling elements are used for bearing great axial force and tilting moment, and two row rolling elements of radial symmetric bear great radial force.Two seat rings and two blowout patches of bearing are integrated, and connected link together with base by pin.Two seat rings carry out radial direction with base with pin and are connected, and connecting pin divides two kinds, and one is connecting pin for positioning, and as shown in Fig. 1 sketch, this pin mainly plays the effect of axially accurately locating and bearing thrust load.Another kind is that connecting pin mainly plays and two seat rings and base linked together and bears the effect of thrust load, as shown in Figure 3.Every four pins are one group, be fixed on connecting sheet realize latch and pull pin with a hydraulic pressure installation.When pin is extracted, base separates with bearing upper part, thus realizes the upper and lower two-part of hoist separately, is convenient to transport.When pin injects pin-and-hole, bearing upper part and base just link together, and start working.
Realize circumferencial direction when bearing is installed by locating stud and V shaped hole accurately to locate.By the insertion of connecting pin or extract and realize bearing rapid-assembling and dismounting.
