hammaspyörävälitys
Hammaspyörävälitys is the Finnish term for gear reduction or gearing. It refers to a mechanical system that uses gears to transmit torque and modify rotational speed between two or more rotating shafts. The primary function of a gear reduction is to increase torque while decreasing rotational speed, or vice versa, depending on the gear ratio.
In a simple gear reduction, two gears with different numbers of teeth are meshed. The smaller gear,
Gear reductions are ubiquitous in mechanical engineering and are found in a vast array of applications. They
