摘要： A ring for shaft bearing of a marine vehicle drive unit has an annular body and a cylindrical active part intended to provide a sliding contact function with another ring at the bearing level. The cylindrical part is segmented into several cylindrical surfaces, each cylindrical surface being attached in a removable manner to the annular body.

摘要： This propulsion unit for an aquatic vehicle consists of a mobile casing mounted in a pivot connection in relation to a hull element of the aquatic vehicle, a drive shaft of a propeller, said shaft being mounted rotatably within the mobile casing by means of at least one bearing consisting of a closed space adapted to be filled with a hydraulic fluid, an electrical machine being adapted to drive the rotary drive shaft in relation to the mobile casing, where the propulsion unit further consists of a module for conditioning the hydraulic fluid contained in the closed space of the bearing. The propulsion unit also consists of a control device to control the conditioning, the control device consisting of a temperature sensor and capable of activating the conditioning of the hydraulic fluid contained in the closed space according to the temperature measured by the temperature sensor.
