Question

How are the gears classified? Explain the role of pressure angle in the gears.​

Answer 1

Answer:

The most common way to classify gears is by category type and by the orientation of axes. Gears are classified into 3 categories; parallel axes gears, intersecting axes gears, and nonparallel and nonintersecting axes gears. Spur gears and helical gears are parallel axes gears.

The pressure angle gives the direction normal to the tooth profile. ... To run gears together properly their pressure angles must be matched. The pressure angle is also the angle of the sides of the trapezoidal teeth on the corresponding rack. The force transmitted during the mating of gear teeth acts along the normal.
