What Are Spur Gears? A Complete Guide to Design, Selection and Applications

Spur gears, fully named spur cylindrical gears and also known as straight-cut gears, have tooth traces running perfectly parallel to the central axis. Designed to transmit rotational motion and torque between parallel shafts, they feature direct, discrete meshing action with a transmission efficiency of 95% to 99%, making them the most fundamental and well-established gear category in mechanical power transmission.
