Gears are something we don’t tend to think about in most industries, even within manufacturing and similar fields to a certain extent. They have been part of our machinery designs for thousands of years, and are an essential element of modern engineering across the board to this day. The practical of applications of gears are almost unlimited, across almost every industry including automobiles, aerospace, medical, military and more.
The manufacturing process for gears is complex, and an in-depth knowledge of all these relevant industries is required for any business in this industry to do well. This is why the market is currently dominated by a relatively small number of leading UK suppliers such as Davall, who design and manufacture precision worm gears, helical and straight bevel gears, gearboxes and more.
Essentially the reason we rely so heavily on gears is due to their simple but effective function. They are a method of transferring energy from one action to another, converting one form of movement into a different one and facilitating a small but vital part of a bigger process. Because of the varied demands that can be placed on them, gears for manufacturing, vehicles and other equipment must all be produced to an extremely high standard. They need to be robust and reliable to ensure the machinery they power isn’t at risk of failure.
This is why the materials chosen when producing gears are extremely important. Making the appropriate selection requires a good understanding of how the gears will be used and what kind of pressure they will be under, including the speed they need to move at, how accurate they need to be, how much strain they must endure and what scale they need to be produced on, among many other factors.
, which can be pressed into the appropriate shape in a process called stamping. This tends to result in relatively poor accuracy and finish but the results are good enough for simple applications. More expensive precision stamping can be used to produce the kinds of gears you would find in a clock or watch. Alternatively, metal power can be pressed and sintered to form stronger and more accurate gears. The most accurate and specific gears have to be machined starting with blanks, having the gear teeth cut into them with high precision. This is slower and more expensive but produces the best quality product.
Since the process of producing gears and the industry as a whole is highly complex, it’s not surprised that the majority of businesses would choose to leave this to the professionals. However, it’s definitely worth considering that this is just one example of a highly specialised area that most of us in the manufacturing industry rely on every day without realising.
