The Spur pinion gear actual pictures as following:

Gear, machine component consisting of a toothed wheel attached to a rotating shaft. Gears operate in pairs to transmit and modify rotary motion and torque (turning force) without slip, the teeth of one gear engaging the teeth on a mating gear. If the teeth on a pair of mating gears are arranged on circles, i.e., if the gears are toothed wheels, the ratios of the rotary speeds and torques of the shafts are constant. If the teeth are arranged on noncircular bodies the speed and torque ratios vary.

Ring and pinion gears for the front and rear end of your vehicle come in a selection of gear ratios that vary how much torque is applied to the wheels of your vehicle. This ratio affects torque, gas mileage, and RPMs. Larger tires take more force to turn and require larger gears in a higher numerical ratio to transfer power properly. Lower numerical gear ratios allow for higher top end speeds when less force is necessary to turn the wheels.
