What is a spur gear? A spur gear is a straight cut gear with the gear hobbing on the rim of the gear and parallel to the bore and rotating axis of the gear. Spur gears are one of the most common and cost-effective types of precision gears. Spur gears mechanically transmit motion and power between parallel shafts, which rotate in opposite directions.
Egg beaters, Electric screwdrivers, mechanical lamps and lighting, oscillating sprinklers, windup alarm clocks, clothes washers and dryers, conveyors, and blenders are a few of the many machines using spur gears. Spur gears are also used in winches, construction equipment, outboard motors, machine tools, lawn and garden equipment, marine hoists, multi-spindle drives, snow throwers, turbine drives, pumps, centrifuges, medical devices, jacks and other power transmission equipment.
