Fogaskerék

Fogaskerék is the Hungarian word for gear. A gear is a rotating machine part having cut teeth, or teeth on its circumference, which mesh with a second gear or other toothed part to transmit torque. Gears are used to transmit power and motion between two rotating shafts. They are one of the most fundamental mechanical components in engineering.

The basic principle of gear operation is that when two gears mesh, the teeth of one gear engage with the teeth of the other, causing both gears to rotate. The ratio of the number of teeth on each gear determines the speed and torque transmitted. A smaller gear driving a larger gear will result in a lower speed but higher torque, while a larger gear driving a smaller gear will result in a higher speed but lower torque.

Gears come in various forms, each designed for specific applications. Common types include spur gears, helical gears, bevel gears, and worm gears. Spur gears are the simplest type and have straight teeth parallel to the axis of rotation. Helical gears have teeth that are cut at an angle, allowing for smoother and quieter operation. Bevel gears are used to change the direction of rotation between intersecting shafts, and worm gears are used for large speed reductions and high torque transmission.

The primary function of fogaskerék in machinery is to alter rotational speed, torque, or direction of rotation. They are found in a vast array of devices, from simple clocks and bicycles to complex industrial machinery, automotive transmissions, and power tools. Their efficiency and reliability make them indispensable in mechanical systems.
