Mechanics: Gears

What is Mechanics

Mechanics is a science which studies the motion and force of an object.

Machines

A machine is any device that makes work easier.

We use machines to:

Transform energy.
Transfer energy.
Multiply or change the direction of the force.
Multiply speed.

All machines are made of combinations of 6 simple machines:

Gears

A gear (engranaje) is a rotating machine with teeth.

Gears are used to magnify or reduce force, change the direction of rotation, or increase or decrease speed.

A gear mesh with another gear to transmit torque.

Mesh: to (cause to) become or be engaged, as the teeth of gears. Engranar

Torque: The measured ability of a twisting part of machinery, as of a shaft, to overcome resistance to such turning. Torque, par

Drive Trains

Two or more gears in line between the input and output are known as a drive train.

Drive trains that are enclosed in housings are called gearboxes.

Simulation: Gear generator

Go to Gear Generator web page.

It is a tool for creating involute spur gears.
In addition it let you compose full gear layouts with connected gears to design multiple gears system with control of the input/output ratio and rotation speed.
Gears can be animated with various speed to demonstrate working mechanism.

Try to make this drive train:

N = número de dientes; PA (Pressure Angle): Ángulo de presión o ángulo de perfiles (Si el ángulo de presión es 0, el diente es paralelo al eje de la rueda, lo que le convierte en un engranaje de dientes rectos)

This is another web page to simulate drive trains. It’s a software for learning about gears.
