Hammasratassüsteem

Hammasratassüsteem, commonly referred to as a gear system, is a mechanical system consisting of two or more meshing gears that transmit torque and motion from one shaft to another. The teeth on the circumference of each gear interlock, causing them to rotate together. When one gear, the input gear, rotates, it forces the other gear, the output gear, to rotate as well. The ratio of the number of teeth on the gears determines the speed and torque transformation. A smaller gear driving a larger gear will reduce the speed but increase the torque, while a larger gear driving a smaller gear will increase the speed and decrease the torque.

Gear systems are fundamental components in a vast array of mechanical devices, from simple clocks and bicycles to complex industrial machinery and automotive transmissions. Their primary functions include changing rotational speed, altering torque, reversing direction of rotation, and transmitting power between shafts that are not parallel. Different types of gears exist, such as spur gears, helical gears, bevel gears, and worm gears, each suited for specific applications and load conditions. The precise design and meshing of gears are crucial for efficient and reliable operation, minimizing wear and noise.
