  • Patent number: 4109361
    Abstract: An elongated unhardened blank is passed between a first pair of rollers where it is conductively heated by supplying current to one of the rollers. Thereafter, the blank is further heated by induction and then passed between a second pair of rollers where it is shaped so as to impart thereto a predetermined cross-sectional configuration. The rollers of the second pair are profiled and the blank is maintained at an elevated temperature by supplying current to one of the rollers. After shaping, the blank is passed between a third pair of rollers. Current is again supplied to one of these rollers. The other roller is of a diameter corresponding to that desired for the finished annular articles and the blank is coiled about this roller. This latter roller is partially immersed in a quenching medium so that the blank is quenched and thereby hardened as it is being coiled. Coiling is continued until the number of convolutions corresponds to the number of annular articles which are to be produced.

  • Patent number: 4030786
    Abstract: A multi-row anti-friction bearing for absorbing simultaneously occurring axial, radial, and torque loads, in which in a divided bearing ring there are provided a first and second or a first, second and third wire body each of which forms one raceway for the anti-friction elements, e.g. in the form of cylindrical rollers. In a non-divided bearing ring there is provided an additional wire body with two raceways and, if desired, a fifth wire body with one raceway only. With each raceway there cooperates one but a different anti-friction element, while the axes of rotation of both anti-friction elements, e.g. cylindrical rollers, cooperating with the two raceways of the additional wire body extend at a right angle to said last mentioned two raceways.
