Door shaft of tower drum door of wind turbine generator
The invention discloses a wind turbine generator tower drum door shaft which comprises a first plane thrust ball bearing, a second plane thrust ball bearing, a door shaft outer sleeve and a rotating shaft arranged in the door shaft outer sleeve and coaxial with a door shaft outer head. The first plane thrust ball bearing and the second plane thrust ball bearing are arranged at the two ends of the rotating shaft in a sleeving mode respectively and connected with the inner wall of the door shaft outer sleeve respectively, the second plane thrust ball bearing is arranged on a door frame, and the outer wall of the door shaft outer sleeve is connected with a tower drum door. Through the arrangement of the first plane thrust ball bearing and the second plane thrust ball bearing, the weight of the tower drum door is transferred to balls of the first plane thrust ball bearing and the second plane thrust ball bearing, friction between the door shaft and the door frame is reduced, and through the arrangement of the oil injection nozzle, the weight of the tower drum door is reduced. The first plane thrust ball bearing and the second plane thrust ball bearing are kept lubricated all the time, friction resistance between the balls and the rotating shaft is reduced, and then the purpose of prolonging the service life of the door shaft is achieved.
本发明公开了一种风电机组塔筒门门轴，包括第一平面推力球轴承、第二平面推力球轴承、门轴外套和设置在门轴外套内且与门轴外头同轴设置的转轴，所述第一平面推力球轴承和第二平面推力球轴承分别套设在所述转轴的两端并分别与门轴外套的内壁连接，所述第二平面推力球轴承设置在门框上，所述门轴外套的外壁与塔筒门连接；本发明通过设置第一平面推力球轴承和第二平面推力球轴承，将塔筒门的重量转移至第一平面推力球轴承和第二平面推力球轴承的滚珠上，减少门轴与门框的摩擦，并通过注油嘴这一设置，使得第一平面推力球轴承和第二平面推力球轴承时刻保持润滑，减少滚珠与转轴之间的摩擦阻力，进而达到延长门轴的使用寿命的目的。
