BEARING AND METHOD OF ASSEMBLING SAME Russian patent published in 1996 - IPC

FIELD: mechanical engineering. SUBSTANCE: multi-row bearing has outer and intermediate races between which rolling bodies are interposed. The inner and outer races have [ - shaped cross-section of different axial sizes. The chute of the races face each other. The intermediated races have H- shaped cross-section of different axial sizes. The [ - shaped and H-shaped races of greater diameter are provided with thrust ways on the sides of the chutes from the inner side. The [ - shaped and H-shaped races of smaller diameter are provided with ways on the outer side. The axes of radial and thrust rolling bodies of one of the rows are preferably mounted at the common axis. The diameter of the thrust rolling bodies is no more then the diameter the radial rolling bodies. The number of intermediate races is even if the bearing has the odd number of rows. If the number of rows is even, the number of intermediate races is odd. The greater races are composed of two rings interconnected via fastening members. The splitting line lies in the middle of the composed race or at the edge of its way without a collar. Dust protecting rings are mounted on the ring projections of the races in the cross-section of the smaller axial dimension. The bearing is assembled in the following order. Half axial dimension of greater races is mounted on the plane. The thrust rolling bodies of the first row are mounted on the rings. The smaller races with radial rolling bodies of all rows are then mounted. Thrust bodies of the second row of all rows are mounted on the rolling bodies. The other half ring of greater diameter are mounted on the thrust bodies and fastened them by way of fastening members. EFFECT: enhanced reliability. 15 cl, 1 dwg
