The invention provides a separable slewing bearing and a device for plugging a pin roll and relates to a slewing bearing for large machinery, wherein the slewing bearing provided by the invention are used for solving the problem that the standard slewing bearing is difficult to separate. The separable slewing bearing is provided with an inner ring and a rolling element which are the same as thoseof the standard slewing bearing, and is characterized in that the outer gear ring of the slewing bearing is divided into an upper part and a lower part, the upper part is provided with a gear ring, and the lower part is provided with a support ring; a connecting hole is arranged on the support ring at the lower part; the gear ring and the support ring at the lower part are connected into a whole by virtue of a pin roll; the connection and separation of the slewing bearing are realized through plugging the pin roll in and out; an annular groove for assembling a plug pin tool is arranged on thesupport ring; and the assembly and disassembly of the pin roll are realized by virtue of a hydro-cylinder. The separation slewing bearing and the device for plugging the pin roll are used in large machinery bearing overturning moment, such as a mobile crane, and have the advantages of simple structure, convenience in operation, safety and reliability.
Description
technical field [0001] The invention relates to a slewing support of a large machine, in particular to a detachable slewing support of a large machine and a special device for plugging and connecting pin shafts. Background technique [0002] Large machinery that bears the overturning moment, such as a mobile crane, has a slewing bearing between its upper and lower bodies. The standard slewing ring is composed of the inner ring 1 connected with the upper body of the crane, the outer ring gear 2 connected with the lower body of the crane, and the rolling element 3 (see figure 1 ). The upper car body is driven to rotate through the rotation of the pinion on the slewing mechanism. When the specifications of the equipment are large and the external dimensions exceed the allowable dimensions, the upper and lower car bodies need to be separated to meet the walking or transportation conditions, and the standard slewing ring cannot meet the use requirements. There are mainly the f...
