Falk Gearboxes 101

A gearbox allows for many different functions, from milling grain to driving cars, to enabling the manufacturing of complex electronics and pharmaceuticals. Here we take a look at the history of gearboxes, industrial gearboxes, and gear reducers.

The History of the Industrial Gearbox

The earliest preserved example we have of a gear is the Antikythera device, found in the Mediterranean Sea and created sometime between 150-100 BC. These gears were used to calculate astronomical phenomena and are described as the oldest example of an analog computer capable of predicting eclipses decades in advance.

Gears also appeared in China around 200-265 AD used as a differential in a chariot, and then as a driver in a mechanical clock in 725 AD. However, the first industrial gearboxes appeared in medieval Europe. This time period is often called the Dark Ages, but significant advances were made. Industrial gearboxes appeared in mills that processed grist, flax, cotton or sawed lumber. They operated by harnessing water and wind power.

Gearbox Technology Today

Modern gears come in a number of forms, which include:

Spurs
Helical and double helical
Bevel
Worm
Epicyclic
Rack
Pinion

Each of these gears is used to transmit either rotary motion or linear motion, multiply force, such as torque, and increase or decrease speed. Gearboxes are mostly found in stationary applications but are also used in industrial applications in myriad industries, such as the agricultural, industrial, and construction industries.

An industrial gearbox is defined as a set of gears within a casing, but the definition in practice is closer to a box containing gear used to increase or decrease the amount of input torque. Gearboxes can be used either manually, or by coupling it to an electric actuator which can increase the output torque. Gearboxes also use different gears depending on how much output is needed and what direction the output axis has.

The History of Falk Industrial Gearboxes

Now that we’re familiar with the history of gearboxes and their functions, let’s learn more about the company whose name has become synonymous with gearboxes in North America: Falk Corporation.

The Falk Corporation is a Milwaukee, Wisconsin manufacturer of gears, gearboxes, gear reducers, and more. They contributed to the state’s reputation as a manufacturing powerhouse. However, they started as a brewery.

After a devastating fire destroyed the brewery in 1892, Herman Falk decided to change industries and got into manufacturing. He began creating wagon couplings before moving to electric street railway supply. Falk created a process known as a “cast welding” to solve the issue of poor joints between the rails. It wasn’t until 1910, that Falk began to create gears.

Electric motors became commonplace in factories at this time, creating a need for high-quality gears that were replacing the belt drives of the 19th century. Machines powered by Falk gearboxes changed the face of manufacturing and became the foundation of the Falk Corporation’s business.

The Falk reversing gear was a pioneering invention that was used to turn propellers on ships during World War II. For the next century, Falk continued to be an innovative leader in the manufacturing of gears, gearboxes, and gear trains for many industries around the world.

In 2005, Falk was sold to Rexnord in Milwaukee, becoming a part of a national network of maintenance and repair services while continuing their primary mission of manufacturing the best quality gears and gearboxes on the market.
