Gear terminology

What is the standardized measurement used to determine gear terminology, gear diameter, number of teeth, and tooth characteristics?

• Inches

• Meters

• Centimeters

• Millimeters

To mesh with each other, how must 2 gears be in terms of their tooth characteristics?

• Irrelevant

• Opposite

• Different

• Similar

What is the theoretical curve along which the gear rolls without slipping on the other gear for transmitting motion?

• Pitch circle

• Module curve

• Tooth curve

• Slip curve

What is the formula for calculating the pitch circle diameter?

• d = m + z

• d = m * z

• d = m / z

• d = m - z

What does the pitch represent in gear terminology?

• Theoretical curve along which the gear rolls without slipping

• Distance between the centers of the shafts

• Distance between any point on one tooth and the next tooth

• Average number of tooth pairs in contact during operation

What is the formula for calculating the pitch?

• P = π.d - Z

• P = π.d + Z

• P = π.d / Z

• P = π.d * Z

What does the contact ratio represent in gear terminology?

• The load shared between teeth

• The distance between any point on one tooth and the next tooth

• The average number of tooth pairs in contact during operation

• The theoretical curve along which the gear rolls without slipping

In a simple gear train, how do the 2 meshing gears rotate?

• In random directions

• In a circular motion

• In opposite directions

• In the same direction

What is the gear terminology for a pair of toothed wheels where one is driving and the other is driven?

• Gear meshing

• Simple gear train

• Compound gear train

• Planetary gear train

What is the gear terminology for a pair of toothed wheels where more than one tooth is actually in contact during meshing?

• Planetary gear train

• Simple gear train

• Contact ratio

• Compound gear train
