Title:
PROPELLER POWER MEASURING SYSTEM FOR VESSEL AND STERN TUBE FOR THE PROPELLER POWER MEASURING SYSTEM
Document Type and Number:
Japanese Patent JP2018090184
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a propeller power measuring system capable of measuring propeller power with a desired high accuracy even when the revolution of a propeller is at a relatively low speed, and a stern tube for the propeller power measuring system.SOLUTION: Provided is a propeller power measuring system which measures propeller power by having a propeller shaft 5 penetrating inside a stern tube 6, being pivotally supported by bearings on both end units in the axial direction of the stern tube, and connecting with a propeller by being protruded underwater from a hull. Thrust torque unbound type bearings 20 with low axial direction friction and rotational direction friction are used as bearings provided in the stern tube for the propeller power measuring system.SELECTED DRAWING: Figure 4
