Abstract
To provide a center-free large rolling bearing in which firstly the ready standby bearing is not subjected to the full operating load during operation of the first bearing and secondly after failure of the first bearing the standby bearing can be used in simple and economic manner, in a center-free large rolling bearing in double constructional form having three bearing races (1, 2, 3), two of which are rotatable independently of each other and with respect to the third, and arranged therebetween rolling element rows (4, 5, 6, 7, 8, 9) for rotational connection of two components (11, 13), a center race (1) being fixedly connectable to a first component (11) and an outer race (2) or an inner race (3) fixedly connectable to a second component (13), it is proposed that the center race (1) consists of a plurality of sub-races (15, 16), that the outer race (2) connected to the second component (13) likewise consists of a plurality of sub-races (20, 21) and a parting line (22) of said outer race is disposed substantially at the same level as the rolling element row (4), bearing the supported load, of said outer race, and that the inner race (3) not connected to the second component (13) has a spacing (18) from the component (13) which is less than the height (19) of the rolling element row (4), bearing the supported load, of the connected outer race (2).
