Spur Gears

Definition: a gear having straight teeth cut on the rim, parallel to the axis of rotation

» Most common & cost-effective type of gear
» Designed to transmit motion & power between parallel shafts, which rotates in the opposite direction
» Plastic, brass, steel, & aluminum are the materials generally used for manufacturing
» Electric screwdrivers, oscillating sprinklers, windup alarm clocks, washing machines, clothe dryers & conveyors are just a few everyday machines where spur gears are used
» Spur gears are also used in construction equipments, machine tools, marine hoists, turbine drives, multi-spindle drives, indexing equipments & roller feeds

Note: in order for spur gears to work together (mesh) they must have the same diametral pitch (pitch) & pressure angle (PA)
