Gears have been used for centuries in various applications, including cars, clocks, and mills. The first use of differential gears dates back to ancient China. Gear technology evolved into electric motors and steam engines during the industrial revolution. Gear ratios affect acceleration and fuel consumption in cars and torque capacity in trucks. Sprockets work similarly to bicycle gears.
Gears have been used by mankind for many centuries. These are the mechanical devices that force objects to create a rotating motion. There are multiple applications that use a ring gear. Many ancient artifacts document the use of a ring gear configuration within gear drives for cars, clocks, locomotives, and aircraft.
The first use of differential gears dates back to the early Western Zhou Dynasty in China. These gears were used as differential torque gears to help move carts. This set of gears forces the wheels of a cart to move as a single unit.
Some of the earliest known gears were made of wood. These first ring gears were used in the area of text mills and grinding mills. In the Middle Ages, many gears were fashioned out of stone. Ring gear technology rapidly evolved into electric motors and steam engines during the industrial revolution.
The automobile is a marvel of mechanical engineering. Each component is designed to work in unison based on gears, electronics, and basic mechanics. The car uses a gear drive that connects to a vehicle’s drive train that makes the wheels move. This gear is connected to the transmission, which is connected to the engine, causing the wheels to turn as the engine accelerates.
Ring gears are available in many different sizes. The gear ratio is the number that represents the size of the crown compared to another gear transmission. This ratio determines how many rotations it will turn before the wheels turn. Lower gear ratios cause the wheels to spin more frequently than higher gear ratios.
In a car, the crown can also affect overall fuel economy. Most performance cars have lower gear ratios, which increases the car’s acceleration. This additional performance comes at the cost of fuel consumption.
Most large trucks require a lower ring gear ratio to increase towing pull. This force is best described as the torque capacity of the vehicle. Gear ratio directly affects torque capacity as it creates more movement and power at less RPM.
A sprocket can best be described by a bicycle gear. The wheels of a bicycle turn easier with smaller gears, but require more rotations to move forward. As the gear is adjusted into a larger and lower gear ratio, it becomes difficult to turn the wheel, but more acceleration occurs with less rotation.
