Shafting & Bearings v1.doc-8/9/2004 3 V. Topic Materials & Information A. Terminology 1. Prime mover - the source of work in a thermodynamic cycle such as a steam turbine, gas turbine, or diesel engine 2. Axial motion – the movement along the length of an object as in along the length of a propulsion shaft 3. Radial motion – the movement that is perpendicular to the length of an object as in around the circumference of a propulsion shaft B. Purposes for a shaft 1. Transfer radial motion from the prime mover to the propeller 2. Transfer thrust from the propeller to the thrust bearing C. Purposes for a bearing 1. Support the weight of the shaft 2. Align shaft-line components 3. Transfer thrust that is produced by the propeller to the ships hull D. Basic types of bearings 1. Journal a. Compensates for radial motion b. Supports the weight of the shaft c. Maintains alignment of shaft-line components d. Sometimes referred to as a radial bearing (this is considered a slang term)
