Claims

[Scope of utility model registration request]

An intermediate shaft in a ship's propulsion shaft system is provided with an elastic joint and an intermediate bearing adjacent to the elastic joint, and an oil pocket is provided by hollowing out the bearing metal in the center of the intermediate bearing in the circumferential direction. The oil pocket and the elastic joint are connected by the oil supply hole formed in the intermediate shaft, and the oil drain hole formed in the intermediate shaft connects the elastic joint and the space between the bearing metal and the check ring. A marine intermediate bearing/elastic joint lubrication device, characterized in that the above-mentioned elastic joints are connected with each other to enable oil lubrication of the elastic joints.
