3 0 0 3
AIM
To make the students gain knowledge in the fundamentals of Mechanics of Machines,
synthesis of various Mechanisms, CAM profiles, theory of gearing, governors,
gyroscopic effects.
OBJECTIVES
At the completion of the course the students are expected to have Knowledge of,
Velocity and acceleration of various kinematic linkages.
Four bar and slider crank mechanisms using analytical and graphical methods.
Cam profiles for different cam followers.
Various parameters of gears and gear trains.
Gyroscopic effect on aeroplanes, ships, two and four wheelers.
UNIT I MECHANISMS 9
34
Introduction – science of mechanisms – terms and definitions – planar, spherical and
spatial mechanisms, mobility classification of mechanisms (indexing mechanism,
reciprocating mechanisms, etc.,) straight line generators – kinematic inversion – slider
crank chain inversions – four bar chain inversions – Grashoff’s law– mechanical
advantage.
Determination of velocities and acceleration in mechanisms – relative motion method
(graphical) for mechanisms having turning, sliding and rolling pair – Coriolis acceleration
– analysis using vector mathematics for a four bar mechanism - analysis using complex
numbers and loop closure equations for slider crank mechanism, inverted slider crank
mechanism – four bar mechanism.
UNIT II SYNTHESIS OF MECHANISMS 9
Classification of kinematics synthesis problems – Tchebycheff spacing – two points
synthesis – slider crank mechanism – three position synthesis – four bar mechanism and
slider crank mechanism – Freudenstein method – analytical and graphical design – four
bar linkage for body guidance – design of four bar linkage as a path generator.
UNIT III CAMS 9
Types of cams and followers – followers motions – uniform, parabolic, SHM, cycloidal
and polynomial – synthesis of cam profiles for different followers – undercutting in cams
– pressure angle – determination of minimum radius of curvature using design charts –
Vamum’s Nomogram – cams of specified contour – eccentric circle cam.
UNIT IV 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, non standard spur
gears – extended centre distance system – long and short addendum system – epicyclic
gear trains – inversions of epicyclic gear trains, specified ratio and torque calculations,
automobile differential, Wilson four speed automobile gear box.
UNIT V CONTROL MECHANISMS 9
Governors – gravity controlled and spring controlled – governor characteristics –
governor effort and power, gyroscopes – gyroscopic forces and couple – forces on
bearing due to gyroscopic action – gyroscopic effects on the movement of air planes and
ships, stability of two wheel drive and four wheel drive, gyroscopic effects in grinding
machines.
