  • Method for forming an end-side toothing arrangement
    Patent number: 8826542
    Abstract: In summary, the invention relates to a method for forming an end-side toothing arrangement of a roiling bearing, in particular a wheel bearing. The aim is to improve the uniformity of the end-side toothing arrangement and to allow a greater tooth depth. This is achieved by two method steps in that, in a first step before the reshaping of an end piece of a hub, a die is axially arranged on the rolling bearing in a preassembled state and, in a second step during the reshaping of the end piece and the shaping of the end-side toothing arrangement, the die radially delimits a radial recess of the rolling rivet collar as it forms. In addition, the die reduces or prevents radial widening of the inner ring.

  • Double roller cage for a double-row cylinder roller bearing with mass compensation
    Patent number: 8821026
    Abstract: A double roller cage for a double-row cylinder roller bearing, with a central ring part (1) from which webs (2, 3) protrude axially on both sides, wherein the webs (2; 3) of one side in each case form a row of bearings (4; 5) together with the rolling bodies arranged therein, wherein every two adjacent webs (2; 3) of a row of bearings (4; 5) delimit a receiving pocket (6; 7) for a rolling body, and in which, at least in one row of bearings (5), the webs (3) are designed so as to taper in the circumferential direction for a radial filling of the receiving pockets (7) with the rolling bearings. So that the double roller cage has satisfactory running behavior and is relatively simple and cost-effective to produce, recesses (12, 12?, 13, 14, 16) are formed on the other of the two rows of bearings (4; 5) in order to produce a symmetrical mass distribution between the two rows of bearings (4; 5).
