Abstract
A roller bearing by far less costly and highly accurate compared with conventional products and having double-cone rollers as rolling elements. A plural number of track pockets are provided facing a pair of parallel bearing plates, double-cone rollers are swivelably and rollably held in the opposing pair of track pockets respectively, both the bearing plates are connected and held in a state relatively swivelable by a connecting mechanism.
Claims13
A roller bearing having double-cone rollers as rolling elements, comprising
- a pair of bearing swivelling means available for incorporation in the fixed side part and the swivelling side part respectively of a swivelling unit of equipment,
- a plural number of track pockets provided in a way to face the pair of bearing swivelling means respectively,
- double-cone rollers bearing the thrust load by being swivelably and rollably held in this opposing pair of track pockets, and
- a connecting means for connecting and holding said pair of bearing swivelling means in a relatively swivelable state,
- thereby constructing said pair of bearing swivelling means in a way to be disposed in a state parallel to each other and perform relative swivelling motions.
A roller bearing having double-cone rollers as rolling elements, comprising
- a pair of bearing plates available for incorporation in the fixed side part and the swivelling side part respectively of a swivelling unit of equipment,
- a plural number of track pockets provided in a way to face this pair of bearing plates respectively,
- double-cone rollers for bearing the thrust load by being swivelably and rollably held in this opposing pair of track pockets, and
- a connecting mechanism for connecting and holding said pair of bearing plates in a relatively swivelable state,
- thereby constructing said pair of bearing plates in a way to be disposed in a state parallel to each other and perform relative swivelling motions.
A method of assembling a roller bearing which includes a plural number of double-cone rollers swivelably and rollably interposed between a pair of parallel bearing plates, said method comprising:
- (a) forming one bearing plate by integrally laminating and fastening a track plate having track forming face and a first holding plate having plural holes;
- (b) provisionally connecting and holding, by a connecting mechanism, a second holding plate having plural pocket forming holes in a state relatively swivelable against said one bearing plate and positioning said one bearing plate and said first holding plate in a state where the pocket forming holes in said one bearing plate and the pocket forming holes in said second holding plate are mutually eccentric, as seen in plane, by the amount of the radius of a swivelling circle of said double-cone rollers;
- (c) inserting and disposing the respective double-cone rollers, aligned in one same direction, form said second holding plate side in a plural number of holding holes, each holding hole having an about oval shape formed by the overlap of the two inner circumferential faces of the pocket forming holes of said first and second holding plates;
- (d) forming the other bearing plate of the pair of parallel bearing plates by integrally laminating and fastening a track plate having track forming face to said second holding plate, and regularly connecting and holding, by said connecting mechanism, said other plate and said one bearing plate in a relatively swivelable state.
