Type of Gears


Spur Gear

Spur gears or straight-cut gears are the simplest type of gear

Pinion

A pinion is a round gear—usually the smaller of two meshed gears—used in several applications, including drivetrain and rack and pinion systems.

Internal Gear

image of an internal gear, called planetary gear for it could create a planet like movement

Rack

rack and pinion

a type of linear actuator that comprises a circular gear (the pinion) engaging a linear gear (the rack)

example of a rack and pinion mechanism, a wine bottle opener

Corkscrew

flower installation

Bevel Gear

to turn the rotationl movement to another axis.

Worm Gear

worm Gear

can only be driven from the shaft side

worm gear driven from the right side, it is working driven from the other side it is locked

music box

Question: why music boxes use worm gears?

gear pressure angle

The higher the pressure angle, the higher the tooth strength. A lower pressue angle gear has less noise. A bigger contact ratio lowers the noise. Decreasing the pressure angle and/or increasing the tooth depth can produce a larger contact ratio.

Task one:

transmit rotational movement from A to B.

Task Two:

same shaft, one disk is rotating clockwise while another one is rotating counter-clockwise
