The History of Spiral Bevel Gear

The first can be traced back primitive gear to over 3,000 years ago. They were made of wood and the pins were attached teeth. Early Greeks used metal gears with wedge shaped teeth; Romans gears in their mills used; Stone gears were used in Sweden in the Middle Ages (Gears Manufacturers). All of the cultures found reasons to use basic leverage energy or motion to convert in either a form they could use in technologically advanced devices of their societies. Gears were used by early engineers for lifting heavy loads through the use of their force-multiplying properties.

One example of this type of application was anchored ship lifts and catapults. Gear technology made its biggest leaps during the industrial revolution in Great Britain during the eighteenth century (eFunda). As more sophisticated machines over the years, technology and manufacturing equipment also developed at a rapid pace. Gears became essential elements in countless devices, from clocks to complex machinery. Today, gears used in many of the machines depend on every day people, such as automobiles.

The main objective is leveraging the manipulation of motion in the form of more potent or usable. The different types of gears allow for endless possibilities in manipulating. The three classes are three gears have parallel axis gears, gears nonparallel-coplanar and nonparallelnoncoplanar equipment.
