Description
Technical Field
The utility model belongs to the technical field of the bearing, concretely relates to revolving stage bearing of integral type structure.
Background
The prior YRT series turntable bearing is mainly applied to a precise numerical control machine tool and can also be used for the configuration of a chuck, a measuring instrument, test equipment and a rotary worktable; as shown in fig. 1, the structure of the bearing is composed of a seat ring 5, a shaft ring 1 and a gasket 4, wherein the gasket 4 is arranged between the shaft ring 1 and the seat ring 5; the outer diameter of the seat ring 5 is the same as that of the shaft ring 1; a set of axial retainer 3 and axial roller 2 assembly are respectively arranged in an upper raceway and a lower raceway formed by the gasket 4, the shaft ring 1 and the seat ring 5; a radial roller 6 is arranged in a roller path formed by the gasket 4 and the shaft ring 1; the bearing has strong axial and radial bearing capacity and inclination rigidity and extremely high rotation precision, but a user needs to fix the working turntable and the bearing together in the using process, and in the process of fixing the working turntable and the bearing into a whole, because the installation steps are more, the installation and processing (deletion) errors are easily caused by accumulated errors and the like, and the precision error of the working turntable is higher.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model aims at providing a revolving stage bearing of integral type structure.
The utility model adopts the following technical scheme for accomplishing the above purpose:
a turntable bearing of an integrated structure is provided with a shaft ring; the shaft ring is a hollow stepped shaft with a small upper part and a large lower part; a small-diameter shaft of the shaft ring is sleeved with a gasket; a radial raceway for mounting a radial roller is formed between the gasket and the small-diameter shaft of the shaft ring; the upper part of the shaft ring is provided with a working turntable which is pressed on the upper end surface of the shaft ring; the working turntable and the shaft ring are coaxially arranged; the outer diameter of the working turntable is larger than that of the shaft ring; the gap between the working turntable and the washer forms an upper axial raceway, and an axial retainer and an axial roller are arranged in the upper axial raceway; the working rotary table is provided with a plurality of fixing holes for fixedly connecting with the using equipment。
A lower axial raceway is formed by a gap between the step surface of the shaft ring and the washer, and an axial retainer and an axial roller are arranged in the lower axial raceway.
The utility model provides a pair of revolving stage bearing of integral type structure directly the pressure equipment with the work revolving stage at the up end of hubcap, uses as the work revolving stage promptly, uses as the seat circle again, has simple structure, compact characteristics, has avoided YRT revolving stage bearing and revolving stage installation because of machining error separately, causes work revolving stage precision error.
