ALIGNMENT STRUCTURE OF SELF-PROPULSION DYNAMOMETER FOR TESTING TOWING WATER TANK

摘要

PURPOSE: An alignment structure of a self-propulsion dynamometer for testing a towing water tank is provided to improve a straight advancing property of a propeller shaft and to reduce noise by connecting the propeller shaft and a dynamometer shaft with a single universal joint. CONSTITUTION: An alignment structure of a self-propulsion dynamometer for testing the towing water tank includes a propeller shaft(108), a dynamometer shaft(101), a single universal joint(103) connecting the propeller shaft and the dynamometer shaft, a connection tool(102) fixed on a dynamometer body(105). A stern tube(104) drawn out a ship body is supported by the connection tool fixed on the dynamometer shaft, and thereby the propeller shaft and the dynamometer shaft are aligned.
