Gears are classified into various types based on their shape, size, and application.

• Spur gears for parallel shafts

• Helical gears for high-speed applications

• Bevel gears for intersecting shafts

• Worm gears for high reduction ratios

• Planetary gears for high torque transmission

• Rack and pinion gears for linear motion

• Internal gears for compact designs

An involute gear is a type of gear with teeth that are cut in an involute shape. Module is the size of the gear tooth. Quality parameters include pitch, pressure angle, and tooth profile. Errors in gear profile include tooth thickness variation, runout, and backlash.

Yes, AutoCAD 2D hands-on experience is essential for drafting.

• AutoCAD is a widely used software for drafting in mechanical engineering.

• 2D drafting is the foundation of engineering design.

• Hands-on experience with AutoCAD 2D helps in creating accurate and efficient designs.

• It also helps in understanding the various tools and features of the software.

• Without hands-on experience, it may lead to errors and inefficiencies in

Heat treatment of steel involves heating and cooling to alter its properties.

• Heat treatment is used to improve the strength, hardness, and ductility of steel.

• Common heat treatment processes include annealing, quenching, and tempering.

• Annealing involves heating the steel to a specific temperature and then slowly cooling it to make it softer and more ductile.

• Quenching involves rapidly cooling the steel to increase its ha...read more
