Abstract
A roller bearing comprising an inner and an outer ring in concentrical arrangement, a series of roller elements being arranged in the space between said rings and being in contact with raceways provided in said rings. The bearing is characterized in that said raceways are provided with parallel grooves, each one of said grooves being arranged in the plane of rotation of said rings and extending along the entire envelope surface, and in mutual correspondence to said inner and outer rings and being arranged for mating interaction with protruding flanges of said roller elements corresponding to said grooves, said protruding flanges extending along the entire envelope surface of said roller elements.

A roller bearing comprising an inner ring and an outer ring arranged concentrically with one another with a space being provided between the inner and outer rings, a series of roller elements arranged in the space between said inner and outer rings, said roller elements possessing protruding annular flanges that extend along an entire circumferential extent of the roller elements, said rollers being in contact with raceways provided in said inner and outer rings, said raceways being provided with parallel grooves each arranged in a plane of rotation of said inner and outer rings, each groove extending along an entirety of a surface of the inner and outer rings and in mutual correspondence to said inner and outer rings for mating interaction with the protruding flanges of said roller elements, and wherein a different distance is provided between two arbitrary, adjacently arranged grooves of said inner and outer rings, and between two adjacently arranged corresponding protruding flanges of said roller elements to cause an internal preload in said bearing.
A roller bearing comprising:
- an inner ring;
- an outer ring arranged concentrically with the inner ring;
- a space provided between the inner and outer rings;
- at least one roller element arranged in the space between said inner and outer rings, said roller element having a circumference and possessing a plurality of outwardly protruding flanges that each extend around the entirety of the circumference of the roller element;
- and
- said inner and outer rings being provided with a plurality of parallel grooves each arranged in a plane of rotation of said inner and outer rings, said grooves extending along the entirety of a surface of the inner and outer rings and matingly interacting with the protruding flanges of said roller element, and wherein a different distance is provided between two arbitrary, adjacently arranged grooves of said inner and outer rings and between two adjacently arranged corresponding protruding flanges of said roller element to cause an internal preload in said bearing.
