Unit I
MECHANISMS 9
Introduction – science of mechanisms – terms and definitions kinematic inversion – slider crank chain inversions – four bar chain inversions – Grashoff’s law-Determination of velocities and acceleration in mechanisms – relative motion method (graphical) for mechanisms having turning, sliding and rolling pair – Coriolis acceleration
Force Analysis Of Mechanisms : Static, Inertia and combined force analysis – graphical and analytical method – slider crank mechanism and four bar mechanism, turning moment diagram and flywheel – applications in engine, punching presses.
Unit II
THEORY OF GEARING 9
Classification of gears, law of gearing, nomenclature – involutes as a gear tooth profile -lay out of an involute gear, producing gear tooth – interference and undercutting – minimum number of teeth to avoid interference, contact ratio, internal gears – cycloid tooth profiles – comparison of involutes and cycloidal tooth forms, Backlash of Marine Gearing. Self-Shift Synchronous Gears.
Unit III

Unit IV
BALANCING 9
Static and dynamic balancing – balancing of rotating masses – balancing of several masses in different planes – balancing of rotors, balancing machine, unbalance due to reciprocating parts -Balancing of inline engines – firing order – balancing of V and W engines – balancing of radial engines – Lanchester technique of engine balancing.
Unit V
VIBRATION 9
Periodic motion – non harmonic periodic motion – undamped free vibration – linear and torsion solution – natural frequency of single degree freedom system — Free vibrations with viscous damping of single degree freedom system and solution – logarithmic decrement.
Forced vibration of single degree freedom system with damping – reciprocating and rotating unbalance – vibration isolation and transmissibility System with two degrees of freedom – shaft with two rotors, system with many degrees of freedom -three rotor system – geared system- torsional vibration of major components in Ships – problems.
Course Outcomes:
On completion of the course the students will be able to:
- Analysis the various forces
- Classify the gears and identify various parameters of gears and gear trains
- Evaluate Governors and gyroscopic forces & couple
- Explain the Concept of Static and dynamic balancing
- Problem analysis due to vibration.
