In the previous articles, we introduced the fundamentals of gears, common gear types, material selection, and the applications of micro gears in robots and drones. However, when selecting or designing gears, many people often encounter the following question: Why do two gears that appear to be almost the same size—even with the same number of teeth—not work properly when installed together? In reality, whether two gears can mesh correctly is not determined solely by their outside diameter....

When people think of gears, they often first think of automotive transmissions, industrial machinery, or large equipment. However, with the development of technology, gear applications are no longer limited to traditional mechanical fields. In recent years, rapidly growing fields such as robots, humanoid robots, drones, medical equipment, and precision automation equipment have widely used various micro gears and precision gears. Although these gears are small in size, they directly affect...

In the previous article, we introduced common types of gears, including spur gears, helical gears, internal gears, bevel gears, and worm gears. However, even when the gear type is the same, the actual material used may be completely different. For example, some gears are made of plastic, some are made of carbon steel or alloy steel, and others use stainless steel or even high-performance engineering plastics. Why can gears be made from such different materials even though they are all gears?...
