Claims

[Scope of utility model registration request]

In a stern tube bearing device that supports a ship propeller shaft via a bearing material and a bearing liner, the bearing liner is
It is composed of a bearing inner liner whose outer peripheral surface shape is formed into a recessed section, and a bearing outer liner that seals the recessed part of the bearing inner liner, and the recessed part is used as a cooling water chamber. A cooling water spout communicating with the cooling water chamber is provided in the gap between the bearing materials or in the bearing material located on the lower half circumferential surface of the bearing material arranged at predetermined intervals on the circumferential surface, and a cooling water spout is provided at the rear end of the recess to be connected to the seawater. An air vent hole and a cooling water outlet are provided, and a cooling water inlet is provided that penetrates the hull-mounted liner of the bearing outer liner and leads to the cooling water chamber, and the cooling water is introduced into the cooling water chamber from the cooling water pipe through the cooling water inlet. A forced cooling type stern tube bearing device characterized in that the cooling water is jetted out from a cooling water spout between the bearing materials to cool the bearing materials.
