1) Spur Gear-Parallel together with co-planer shafts connected yesteryear gears are called spur gears. The scheme is called spur gearing.
Spur gears stimulate got take away teeth together with are parallel to the axis of the wheel. Spur gears are the most mutual type of gears. The advantages of spur gears are their simplicity inward design, economic scheme of industry together with maintenance, together with absence of goal thrust. They impose exclusively radial loads on the bearings.
Spur gears are known every bit irksome speed gears. If dissonance is non a serious blueprint problem, spur gears tin live on used at nigh whatever speed.
2) Helical Gear-Helical gears stimulate got their teeth inclined to the axis of the shafts inward the shape of a helix, thus the elevate helical gears.
These gears are commonly idea of every bit high speed gears. Helical gears tin accept higher loads than similarly sized spur gears. The motion of helical gears is smoother together with quieter than the motion of spur gears.
Single helical gears impose both radial loads together with thrust loads on their bearings together with so request the role of thrust bearings. The angle of the helix on both the gear together with the must live on same inward magnitude but contrary inward direction, i.e., a correct manus pinion meshes alongside a left manus gear.

3) Herringbone Gear - Herringbone gears resemble 2 helical gears that stimulate got been placed side yesteryear side. They are oftentimes referred to every bit "double helicals". In the double helical gears arrangement, the thrusts are counter-balanced. In such double helical gears in that location is no thrust loading on the bearings.
4) Bevel/Miter Gear-Intersecting but coplanar shafts connected yesteryear gears are called bevel gears. This scheme is known every bit bevel gearing. Straight bevel gears tin live on used on shafts at whatever angle, but correct angle is the most common. Bevel Gears stimulate got conical blanks. The teeth of take away bevel gears are tapered inward both thickness together with molar height.
Spiral Bevel gears: In these Spiral Bevel gears, the teeth are oblique. Spiral Bevel gears are quieter together with tin accept upwards to a greater extent than charge every bit compared to take away bevel gears.
Spiral Bevel gears: In these Spiral Bevel gears, the teeth are oblique. Spiral Bevel gears are quieter together with tin accept upwards to a greater extent than charge every bit compared to take away bevel gears.
Zero Bevel gear: Zero Bevel gears are like to take away bevel gears, but their teeth are curved lengthwise. These curved teeth of null bevel gears are arranged inward a agency that the effective spiral angle is zero.
5) Worm Gear- Worm gears are used to transmit ability at 90° together with where high reductions are required. The axes of worm gears shafts cross inward space. The shafts of worm gears prevarication inward parallel planes together with may live on skewed at whatever angle betwixt null together with a correct angle.In worm gears, ane gear has screw threads. Due to this, worm gears are quiet, vibration gratuitous together with laissez passer on a smoothen output.Worm gears together with worm gear shafts are nigh invariably at correct angles.
6) Rack together with Pinion- A rack is a toothed bar or rod that tin live on idea of every bit a sector gear alongside an infinitely large radius of curvature. Torque tin live on converted to linear forcefulness yesteryear meshing a rack alongside a pinion: the pinion turns; the rack moves inward a take away line. Such a machinery is used inward automobiles to convert the rotation of the steering wheel into the left-to-right motion of the necktie rod(s). Racks also characteristic inward the theory of gear geometry, where, for instance, the molar shape of an interchangeable fix of gears may live on specified for the rack (infinite radius), together with the molar shapes for gears of item actual radii together with so derived from that. The rack together with pinion gear type is employed inward a rack railway.
7) Internal & External Gear- An external gear is ane alongside the teeth formed on the outer surface of a cylinder or cone. Conversely, an internal gear is ane alongside the teeth formed on the inner surface of a cylinder or cone. For bevel gears, an internal gear is ane alongside the pitch angle exceeding xc degrees. Internal gears create non effort management reversal.
8) Face Gears- Face gears transmit ability at (usually) correct angles inward a round down motion. Face gears are non real mutual inward industrial application.
9) Sprockets-Sprockets are used to run chains or belts. They are typically used inward conveyor systems.
Gears may also live on classified according to the seat of axis of shaft:
a.Parallel
1.Spur Gear
2.Helical Gear
3.Rack together with Pinion
b. Intersecting
Bevel Gear
c. Non-intersecting together with Non-parallel
