Spur Gears

  • Related terms: straight cut gears, spur wheels, parallel shaft gears, pinion gears
  • Cylindrical gears with straight teeth cut parallel to the shaft axis, used to transmit motion and power between parallel shafts. Simple, efficient and easy to manufacture, they are the most widely used gear type in gearboxes, machinery, conveyors, pumps and automation equipment.

Mitre Gears

  • Related terms: miter gears, 1:1 bevel gears, right angle gears, equal ratio bevel gears
  • A type of bevel gear with an equal number of teeth on each gear, giving a 1:1 ratio and changing the drive direction by 90 degrees. They are used where a change in shaft direction is needed without altering speed, such as in machine tools, agricultural equipment and power transmission systems.

Bevel Gears

  • Related terms: bevel wheels, conical gears, right angle drive gears, bevel gear sets
  • Cone-shaped gears that transmit power between intersecting shafts, usually at a 90 degree angle. Available in a range of ratios, they allow both a change in direction and a change in speed, and are common in differentials, hand drills, printing presses and industrial gearboxes.

Racks

  • Related terms: gear racks, rack and pinion, toothed racks, linear gear racks
  • Straight bars with teeth cut along one face that mesh with a pinion gear to convert rotary motion into linear motion, or vice versa. Used in CNC machinery, gantries, sliding gates, steering systems and automation equipment where accurate linear movement is required.
