Gear hobs: what are they?

Gears are essential in many devices, and creators play a vital role in their production. Hobs are tools used to cut and shape gear teeth, and their automation has improved gear manufacturing. The demand for gears continues to grow, and hob production is almost as big an industry as gear manufacturing. As long as machinery is needed, there will be a need for gears and their makers.

Many of the devices we rely on for the goods and services we use every day are based on the creation and proper construction of gears. From machinery that is used to make clothing to heavy machinery that is used to construct buildings, gears play an important role. By association this means that the creator is an essential tool in our society. Here is some information about the creators, what they do and why we need it.

Basically, creators have an essential role to play. Hobs are tools that are used in cutting and shaping the teeth found on gears. Without them, the interplay of gears to drive everything from elevators to the inner workings of sewing machines would have to be rethought.

Making a gear today is much easier than in the past. The earliest example of a hob was a hand tool that would be used to carve out the teeth of a gear that were completely uniform in size and proportions. Over the years, larger gear makers arose and were able to use a semi-automated method of gear manufacturing. With the use of a cylindrical milling base and correctly positioned segments on the milling base, the gear makers’ tooth cutters could cut into the metal, making exact duplications all along the gear. The result was identical teeth that would allow the gear to easily match operation with another gear.

Today, many manufacturing companies use fully automated hobs to produce quality gears. As the demand for gears continues to grow each year, improvements in the production of hobs that will produce more gears per hour also continue to be improved. The manufacturing of hobs is almost as big an industry as the manufacturing of gears themselves.

Many manufacturing companies that maintain museums of how products were made in the past will have examples of hand makers who helped make gears before the 19th century and earlier. Along with these fully manual hobs will be samples of some of the earliest semi-auto hobs and finally, examples of newer technology demonstrating the fully automated process modern hobs use to make gears today. Some hob manufacturers also have interesting literature on the history of hobs, including details on how modern hobs can produce thousands of gears in a single hour.

As long as the company needs machinery, there will be a need for gears as part of the operation. And as long as the gears are around, the makers will be busy producing perfectly sculpted gears with a full set of uniform teeth.
