Spur gear. Spur gears or straight-cut gears are the simplest type of gear. They consist of a cylinder or disk with teeth projecting radially. Viewing the gear at 90 degrees from the shaft length (side on) the tooth faces are straight and aligned parallel to the axis of rotation. Looking down the length of the shaft, a tooth's cross section is ...

Two intermeshing spur gears rotating at different velocity due to differing gear ratio. A gear [1] [2] or gearwheel [3] [4] [5] is a rotating machine part typically used to transmit rotational motion and/or torque by means of a series of teeth that engage with compatible teeth of another gear or other part.
Meshing of two spur gears with involute external teeth. z 1 = 20, z 2 = 50, α = 20°, ξ 1 = ξ 2 = 0, ISO 53:1998. The lower (green) gear is the driving one. The line of contact, which is the locus of all teeth contact points, is shown in blue.
