Abstract
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 the portable dismounting combined type of large-tonnage turntable bearing, it belongs to crane lifting matched with devices part field.
Background technique
In recent years, reinforcement along with 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 develops rapidly of the industries 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 begins to develop hoister in large tonnage one after another, and external well-known hoist manufacturing enterprise has also invested China to sight, has strengthened 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 are particularly harsh to the requirement of its supporting turntable bearing, require to overcome huge axial force, radial force and tilting moment.So the turntable bearing of design has high bearing capacity.Owing to bulky, the transportation before and after using also is urgent problem simultaneously.
Summary of the invention
Defective in view of prior art exists the invention provides the portable dismounting combined type of large-tonnage turntable bearing, has 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 by twin shaft circle, two-seater circle and base and forming, be provided with 12 linarity raceways in the bearing, the twin shaft circle comprises the first blowout patche and the second blowout patche, and the two-seater circle comprises the first seat ring and the second seat ring; Bearing shaft is to four row rolling elements of symmetry, two row rolling elements of radial symmetric, and two-seater circle and the twin shaft circle of bearing are integrated, and connect with base by pin to link together; The first seat ring, the second seat ring radially are connected with base by locating stud.Described base directly upwards is provided with V shaped hole, and locating stud radially passes V shaped hole and the first seat ring, the second seat ring, locks by cotter pin; Circumferencial direction is accurately located when realizing that by locating stud and V shaped hole bearing is installed.Described bearing also comprises two-seater circle and the base connecting pin that links together and the hydraulic pressure installation that is fixed on the connecting sheet; Four connecting pins are one group, and hydraulic pressure installation carries out latch and pulls pin; When connecting pin was extracted, part separate on base and the bearing, thereby realized that two-part separately when connecting pin injects pin-and-hole, partly just link together with base on the bearing up and down, started working.
After adopting such scheme, compared with prior art have following beneficial effect: axle is comprised of twin shaft circle, two-seater circle and base, and bearing has 12 linarity raceways, has realized multidirectional carrying.Axially all four row rolling elements of symmetry are used for bearing great axial force and tilting moment, and two row rolling elements of radial symmetric bear great radial force.Circumferencial direction is accurately located when realizing that by locating stud and V shaped hole bearing is installed.Insertion by connecting pin or extract and realize bearing rapid-assembling and dismounting.
