Sprockets are wheels with teeth that can mesh with other sprockets to create machines with varying gear ratios. Gear ratios determine the amount of mechanical power or multiplication created by two gears. Cogwheels allow machines to perform tasks beyond the singular force of people or horses, and can produce high-speed functions with low-speed input. Automotive […]

Gear wheels, also known as gears, are mechanical parts found in many machines including automotive transmissions. They have teeth or cogs that allow them to transmit power and direction to other gears. This concept has been understood for millennia and was used in the Antikythera Mechanism, an ancient Greek astronomical device. During the industrial revolution, […]
