hammaspyöriin
Hammaspyöriin is the illative plural form of hammaspyörä, the Finnish term for a gear wheel. In mechanical engineering, hammaspyörät (gears) are toothed wheels that mesh with other gears to transmit motion and torque between shafts. The basic principle is a constant speed ratio governed by the number of teeth on each gear.
Gears change rotational speed, direction, and torque. The teeth ensure close contact and smooth power transmission,
Common types include spur gears with straight teeth, which are simple and robust; helical gears with angled
Design parameters in modern gear systems include module or diametral pitch, pressure angle, and face width.
Overall, hammaspyöriin represents a fundamental concept in power transmission, encompassing a variety of gear types and
