Gears and Gear Ratios Pop Flashcard

Front

What is a gear ratio?

Back

A gear ratio is the ratio of the number of teeth on two gears that are meshed together, determining how many times one gear turns in relation to the other.

Front

How do you calculate the gear ratio?

Back

The gear ratio can be calculated by dividing the number of teeth on the driven gear by the number of teeth on the driving gear.

Front

What does a gear ratio of 60:36 indicate?

Back

It indicates that for every 60 teeth on the driven gear, there are 36 teeth on the driving gear, resulting in a specific mechanical advantage.

Front

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

Back

The larger gear typically provides more torque and can turn slower compared to the smaller gear.

Front

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

Back

The smaller gear makes the larger gear turn in the same direction and can increase the speed of the output.

Front

What happens to torque when speed increases in a gear system?

Back

When speed increases, the value of torque decreases, as they are inversely related in a gear system.

Front

What is torque in the context of gears?

Back

Torque is a measure of the rotational force applied by a gear, which determines how much work it can do.

Front

What is the significance of gear train B in terms of torque?

Back

Gear train B is designed to provide more torque compared to other configurations, making it suitable for heavy loads.

Front

What is the relationship between gear size and speed?

Back

Generally, smaller gears rotate faster than larger gears, but larger gears provide more torque.

Front

What is the output gear in a gear system?

Back

The output gear is the gear that receives power from the input gear and delivers the final output motion.
