Abstract
The utility model provides a large-scale synchronous alternating current motor is with subdivision cylindrical roller bearing, its characterized in that: smooth arc-shaped surface grooves are formed in the outer sides of the corresponding pair of inner half rings, smooth arc-shaped surfaces are formed in the inner sides of the corresponding pair of outer half rings, rollers are arranged between the outer side faces of the inner half rings and the inner side faces of the outer half rings, retainer seats are arranged between the rollers, and retainer covers are mounted on the axial side faces of the retainer seats through screws. The method has the advantages of saving the overall time and working requirements for mounting the bearing, having strong interchangeability with standard bearings and the like.
Description
Technical Field
The utility model relates to a subdivision cylindrical roller bearing especially is about a large-scale for alternating current synchronous motor subdivision cylindrical roller bearing.
Background
The conventional 3500KW alternating-current synchronous super-large motor for a rolling mill adopts a static-pressure oil film bearing, is poor in use effect, inconvenient to install, disassemble and maintain, and wastes time and labor.
Disclosure of Invention
The utility model aims at providing an easily installation, the large-scale for synchronous AC motor subdivision cylindrical roller bearing of dismantling.
The technical solution of the utility model is that:
the utility model provides a large-scale subdivision cylindrical roller bearing for synchronous machine of interchange which characterized in that: smooth arc-shaped surface grooves are formed in the outer sides of the corresponding pair of inner half rings, smooth arc-shaped surfaces are formed in the inner sides of the corresponding pair of outer half rings, rollers are arranged between the outer side faces of the inner half rings and the inner side faces of the outer half rings, retainer seats are arranged between the rollers, and retainer covers are mounted on the axial side faces of the retainer seats through screws.
Compared with the prior art, the utility model have following advantage: the overall time and work requirements for mounting the bearing are saved, the interchangeability of standard bearings and the free compensation of axial length changes.
Drawings
Fig. 1 is a schematic view of the present invention.
In the figure: 1. half inner ring, 2, retainer seat, 3, roller, 4, half outer ring,
5. cage cover, 6, screws.
Detailed Description
The embodiment is described by combining the accompanying drawings, wherein smooth arc-shaped surface grooves are formed in the outer sides of a corresponding pair of inner half rings 1, smooth arc-shaped surfaces are formed in the inner sides of a corresponding pair of outer half rings 4, rollers 3 are arranged between the outer side surfaces of the inner half rings 1 and the inner side surfaces of the outer half rings 4, retainer seats 2 are arranged among the rollers 3, and retainer covers 5 are arranged on the axial side surfaces of the retainer seats through screws 6.
Compared with the integral bearing, the utility model can better adapt to the required working environment, is easier to install in a limited position, and the equipment adjacent to the two sides of the bearing and other equipment on the shaft do not need to be moved away when the bearing is replaced, thereby saving the total time and working requirement for installing the bearing;
free compensation of axial length variation: the linear expansion of the heating drying cylinder is smoothly compensated in the cylindrical roller bearing, and the compensation is carried out between the hardened inner ring raceway with good lubrication and the hardened rolling body;
the utility model discloses and standard bearing's interchangeability: all the standard bearings of the 22, 23, 30, 31 and 32 series can be replaced without major modification of the bearing housing.
