THEORY OF MACHINES

LPTC

3003

OBJECTIVE:
• To introduce the students the theory of machines pertaining to agricultural engineering.

UNIT I

TERMINOLOGY

9

Definitions - Kinematic links - Pairs - Chain - Machines and mechanism - Types and uses – Kinematic inversion of four bar chain and slider crank mechanism. Velocity and acceleration in simple mechanisms - Vector polygon and instantaneous centre methods – Coriolis component of acceleration.

UNIT II

FRICTION AND APPLICATIONS

9

Sliding and rolling friction –friction in screw threads-Bearing and lubrication- Friction clutches- Belt drives- Friction aspects in brakes.

UNIT III

MOTION OF CAM AND FOLLOWER

9

Cam and follower - types - application – displacement diagrams - profile layout for uniform velocity - Uniform acceleration and retardation - simple harmonic and cycloidal motion.

UNIT IV

GEARS AND GEAR TRAINS

9

Gears - classification - terminology -law of gearing - tooth profile - interference between rack and pinion. Gear trains - simple - compound reverted. Simple epicyclic gear trains.

UNIT V

FLYWHEEL AND BALANCING

9

Inertia - turning moment - flywheel - fluctuation of speed and energy. Balancing of rotating masses and reciprocating masses.

TOTAL : 45 PERIODS

OUTCOMES: At the end of the course the student will be able to
• Basic knowledge on the friction applications, gear and gear trains.
• Learn the fundamentals related to motion of cam and follower and fly wheel balancing
