The invention relates to the technical field of ships, and discloses a stern tube rear bearing oil guide groove which comprises a rear shaft shell and a rear bearing, a ship driving main shaft is installed in the rear bearing, a first sealing sleeve and a second sealing sleeve are installed at the two ends of the rear bearing respectively, and an oil inlet pipe is installed on the outer wall of the first sealing sleeve; an oil outlet pipe is installed on the outer wall of the second sealing sleeve, a centrifugal oil guide mechanism is fixedly installed on the outer wall of the ship driving main shaft, and the centrifugal oil guide mechanism is located in the second sealing sleeve. According to the stern tube rear bearing oil guide groove, through the arrangement of the rear shaft shell, the rear bearing, the ship driving main shaft, the first sealing sleeve, the second sealing sleeve, the oil inlet pipe, the oil outlet pipe and the centrifugal oil guide mechanism, lubricating oil can be directly conveyed to the stern tube rear bearing through the oil guide groove design, and the oil film building thickness of the rear bearing is guaranteed to the maximum extent; no matter from theoretical calculation or practical application, the accident of high-temperature heating caused by insufficient oil supply of the stern tube rear bearing is limited.
本发明涉及船舶技术领域,且公开了艉管后轴承导油槽,包括:后轴壳和后轴承,所述后轴承的内部安装有船舶驱动主轴,所述后轴承的两端分别安装有第一密封套筒和第二密封套筒,所述第一密封套筒的外壁安装有进油管,所述第二密封套筒的外壁安装有出油管,所述船舶驱动主轴的外壁固定安装有离心导油机构,且离心导油机构位于第二密封套筒的内部。该艉管后轴承导油槽,通过设置的后轴壳、后轴承、船舶驱动主轴、第一密封套筒、第二密封套筒、进油管、出油管和离心导油机构,能够采用导油槽设计直接将滑油输送到艉管后轴承,最大程度上保证了后轴承的油膜建立厚度,不论是从理论计算还是实际应用,都限制了艉管后轴承因供油不足而导致高温发热的事故发生。
