Automation & Robotics: Speed & Torque

Front

What is torque?

Back

Torque is a measure of the rotational force applied to an object, typically measured in Newton-meters (Nm). It determines how effectively a force can cause an object to rotate.

Front

How does the number of teeth on a gear affect its speed?

Back

The speed of a gear is inversely proportional to the number of teeth it has. More teeth mean slower rotation, while fewer teeth mean faster rotation.

Front

If a driving gear has 36 teeth and a driven gear has 60 teeth, will the driven gear turn faster, slower, or at the same speed?

Back

The driven gear will turn slower.

Front

What happens to the speed of a driven gear if it has fewer teeth than the driving gear?

Back

The driven gear will turn faster than the driving gear.

Front

In a gear train, what is the role of idler gears?

Back

Idler gears are used to transfer motion between the driving and driven gears without changing the speed ratio.

Front

If a driving gear has 72 teeth and the driven gear also has 72 teeth, what is the speed relationship?

Back

The driven gear will turn at the same speed as the driving gear.

Front

What is the relationship between speed and torque in gears?

Back

As speed increases, torque decreases, and vice versa. This is due to the conservation of energy in a mechanical system.

Front

If a driving gear has 24 teeth and a driven gear has 72 teeth, what happens to the torque of the driven gear?

Back

The torque of the driven gear will increase.

Front

What is a gear ratio?

Back

A gear ratio is the ratio of the number of teeth on two meshing gears, which determines the speed and torque relationship between them.

Front

How do you calculate the gear ratio?

Back

Gear ratio = Number of teeth on driven gear / Number of teeth on driving gear.
