The invention relates to a thrust bearing comprising cylindrical rollers arranged circumferentially in a bearing race, the axes of rotation of the cylindrical rollers being directed radially towards the central axis of the thrust bearing and each having a contact surface extending around the cylindrical roller and in the longitudinal direction thereof, the cylindrical rollers comprise at least radially adjacent first roller pairs, the radially inner first roller in each pair being arranged with its axis of rotation aligned with the axis of rotation of the radially outer first roller of the pair, and the cylindrical rollers comprise second rollers, at least one of the second rollers is arranged in the circumferential direction between adjacent first roller pairs, the at least one second roller being offset in the radial direction with respect to the radially outer first rollers, the at least one second roller being arranged in the circumferential direction between the radially outer first rollers, wherein said radial offset is such that a midline located intermediate along the length of the contact surface of each radially outer first roller and a quarter line located at a quarter from the longitudinal end of said contact surface along the length of the contact surface of said at least one second roller at said joint of said radially outer first roller The contact surface is circumferentially aligned within +/-5% of the length.
一种推力轴承,其包括周向布置在轴承座圈中的圆柱形滚子,所述圆柱形滚子的旋转轴线径向地指向所述推力轴承的中心轴线并且各自具有绕所述圆柱形滚子并且沿其纵向延伸的接触表面,所述圆柱形滚子包括至少径向相邻的第一滚子对,每对中的径向内部第一滚子被布置成其旋转轴线与所述对的径向外部第一滚子的所述旋转轴线对准,并且所述圆柱形滚子包括第二滚子,至少一个所述第二滚子在周向方向上被布置在相邻的第一滚子对之间,所述至少一个第二滚子相对于所述径向外部第一滚子在径向方向上偏移,所述至少一个第二滚子周向布置在所述径向外部第一滚子之间,其中所述径向偏移使得位于沿每个径向外部第一滚子的接触表面的长度的中间处的中线与位于沿所述至少一个第二滚子的接触表面的长度从其所述接触表面的纵向端起的四分之一处的四分之一线在所述径向外部第一滚子的所述接触表面的所述长度的正负5%内周向对准。
