Hand gears are human-powered gear systems that have been around for thousands of years. They have been used in early technology and weaponry, and in modern times, they still have an important place in closely monitored systems. Hand gears can be more complex than machine gears due to the lower horsepower of human strength.
A hand gear is any form of human-powered gear system. These systems typically involve turning a crank to move a larger object. Hand gears have been around since the first human machinery arose thousands of years ago. Even though a hand gear doesn’t have a specific energy source outside of human strength, that doesn’t mean it’s necessarily simplistic. Often hand gear systems are much more complicated than they appear.
These early systems were often simple gears with basic functions. Some companies viewed them more as mathematical puzzles than actual devices. As time progressed, hand equipment became a staple of early technology and weaponry. It became possible for one or two men to do the job more as basic gears were added in certain milling, building or siege systems.
As time went on, the uses of the hand tackle changed. Some work performed using a hand tool has been transferred to hydraulic power. On the other hand, technology had improved to the point where new areas of manufacturing and construction were done using manual systems.
Eventually, nearly every major manufacturing process was done with gear systems. Some used steam or water as a motivating force, but many machines used human strength. This was especially true in the textile industry, where massive looms and hand-held sewing machines replaced older methods.
In modern times, a hand gear still has an important place. In some cases, they are relics from an earlier era. People see these hand gear systems as a connection to an earlier time when electronics and gadgets didn’t rule the world. Hand-cranked gates are one example. These systems could be modernized into an automatic system, but crank gate systems have a nostalgia and classy factor that many people like.
Another common place for a hand gear is in closely monitored systems. In many cases, humans can manually control pressure better than a machine. Humans can anticipate problems and create subtle variations in pressure and motion that many automated systems cannot match. These types of systems are common in variable high pressure conditions such as shipping or construction.
Often a hand gear is much more complex than a corresponding machine gear. A machine can make a much greater force than human force available to the system. To compensate for their lower horsepower, human power transmission systems use complex gear ratios to increase the pressure exerted on a work area. This results in a more complex system, often with a greater number of gears.
