<p>The unit (10) consisting of a bearing of conical rollers (11) provided with an interior conical ring (12) designed to be connected to a fixed or turning shaft (21,61,81), of an exterior conical ring (13) arranged to be coupled to a turning or fixed bearing (22,62,82) and a series of conical rollers (14) fitted between the interior and exterior rings. The rollers are contained by a cage (15). The unit further contains an axial stop (16) on which the rollers act to oppose the reaction force of the axial component of the loads to the rollers by the shaft and/or the bearing. The axial stop (16) is made up of a support element (30,40,50,70,90) independent of the interior (12) and exterior (13) rings, this support element being coupled in rotation with the rollers (14) in a manner to limit the lateral friction of the rollers.</p> |
