Types . There are four basic types of gears; spur, helical, bevel, and spiral bevel. See Figure 4. Spur gears are the most common. A spur gear has teeth that are uniformly spaced around the outer surface. The teeth are aligned in a direction that is parallel to the gear axis. A spur gear is designed to mesh with another

Gear types may be grouped into five main categories: Spur, Helical, Bevel, Hypoid, and. Worm. Typically, shaft orientation, ef- ficiency, and speed determine 

1.3 Types of gears and their applications. 1.4 Spur Gear. 1.5 Helical Gear. 1.6 Double helical or Herringbone Gear. 1.7 Internal Gear. 1.8 Rack and pinion.

Types of Gears • Spur gears have teeth parallel to the axis of rotation and are used to transmit motion from one shaft to another, parallel, shaft. • Helical gears have teeth inclined to the axis of rotation. Helical gears are not as noisy, because of the more gradual engagement of the teeth during meshing.

Types of Gears: • Spur Gear • Helical Gear • Herringbone Gear • Bevel Gear • Worm Gear • Rack and Pinion • Internal and External Gear • Face Gear Spur Gear Gears having cylindrical pitch surfaces are called cylindrical gears.

fTypes of Gears • Spur Gear • Helical Gear • Bevel Gear • Internal Gear • Worm Gear fSpur Gear • Spur gears have their teeth parallel to axis and are used for transmitting power between two parallel shafts. • They are simple in construction, wasy to manufacture and cost less. • They have highest efficiency and excellent precision rating.
