PLTW Gears

Front

What are Idler Gears?

Back

Idler gears are gears that do not affect the gear ratio or gear reduction in a system, regardless of the number of teeth they have.

Front

What happens when the driving gear is smaller than the driven gear?

Back

When the driving gear is smaller than the driven gear, torque increases and speed decreases.

Front

What is the function of a smaller gear in a gear system?

Back

The smaller gear makes the larger gears turn in the same direction.

Front

What happens to torque when speed increases?

Back

When speed increases, the value of torque decreases.

Front

What is the gear ratio when gears are equal in size?

Back

The gear ratio is 1:1 when the gears are equal in size.

Front

Define Gear Ratio.

Back

Gear ratio is the ratio of the number of teeth on two meshing gears, determining the relationship between the input speed and output speed.

Front

What is Torque?

Back

Torque is a measure of the rotational force applied to an object, often resulting in its rotation.

Front

How does gear size affect speed and torque?

Back

A smaller driving gear increases torque and decreases speed, while a larger driving gear decreases torque and increases speed.

Front

What is the role of a Driving Gear?

Back

The driving gear is the gear that provides the input motion and power to the system.

Front

What is a Driven Gear?

Back

The driven gear is the gear that receives motion and power from the driving gear.
