09ME605          DESIGN OF TRANSMISSION SYSTEMS            

OBJECTIVE:                                                                                             

• To gain knowledge on the principles and procedure for the design of power Transmission components.
• To understand the standard methods available for Design of Transmission systems.

                        (Use of approved Design data books may be permitted in the examination)

1. DESIGN Of BELT DRIVES, CHAIN DRIVES AND WIRE ROPES                                

Selection of flat belts and pulleys – Selection of V-belts and pulleys – Selection of Transmission chains and Sprockets, Wire ropes and pulleys, Design of pulleys and sprockets.

2. DESIGN Of Spur and Helical Gears                                                        

Gear drives- Spur gears-Gear Terminology-Speed ratios and number of teeth- Force analysis -Tooth stresses -  Gear materials – Module and Face width- Power rating calculations based on strength and wear considerations - Parallel axis Helical Gears – Pressure angle in the normal and transverse plane- Equivalent number of teeth- forces and stresses. Estimating the size of the helical gears.

3. DESIGN Of BEVEL GEARS AND Worm gears                                                       

Bevel gears – Types - Gear materials - Terminology – Tooth forces and stresses, equivalent number of teeth - Design of bevel gears based on strength and wear conditions. Worm Gears - Merits and demerits- Terminology. Thermal capacity, materials-forces and stresses, efficiency, estimating the size of the worm gear pair.
