Abstract
An antifriction bearing assembly having two rows of bearing elements running in races of different diameters and laying approximately in the same radial plane. The bearing races and mounting rings are made up of an assembly of flange members formed from sheet metal or thin metal plate and including an inner and an outer flange each defining a race for the inner or the outer row of bearing elements and an intermediate flange defining either an inner or an outer race for each of the rows of bearing elements. The bearing is mounted on two relatively rotatable members by directly securing the rotatable members to the bearing's ring structure which is formed as an integral part of the flanges.
Claims16
An antifriction bearing adapted to be mounted between two relatively rotatable mechanical members, said bearing comprising two annular rows of bearing elements mounted approximately in the same radial plane, an intermediate flange formed from a sheet metal material adapted to be secured to one of said mechanical members and providing an inner race for one of said two rows of bearing elements and an outer race for the other of said two rows, an inner and an outer flange formed from a metal sheet material and being adapted to be secured to the other of said mechanical members, each of said inner and outer flange providing another race one for each of said two rows of bearing elements, said inner flange having a surface inclined with respect to the rotational axis of the antifriction bearing to contact the bearing elements in the other of said rows at points which are closer to the bearing axis than are the centers of the bearing elements in the other of said rows, each bearing element in both of said rows of bearing elements contacting said flanges at points on a line which forms an acute angle with respect to the rotational axis of the antifriction bearing, one of said inner and outer flanges having an integrally formed annular portion in the form of a tubular sleeve concentric with the axis of the bearing and adapted to be directly fitted on a corresponding cylindrical part of said other mechanical member.
An antifriction bearing adapted to be mounted between two relatively rotatable mechanical member, said bearing comprising two annular rows of bearing elements mounted approximately in the same radial plane, an intermediate flange formed from a metal sheet material adapted to be secured to one of said mechanical members and providing an inner race for each of said two rows of bearing elements, an inner and an outer flange formed from a metal sheet material and being adapted to be secured to the other of said mechanical members, each of said inner and outer flange providing another race one for each of said two rows of bearing elements, at least one of said inner, outer and intermediate flange having an integrally formed annular portion in the form of a tubular sleeve concentric with the axis of the bearing and adapted to be directly fitted on a corresponding cylindrical part of said other mechanical member.
