For making gears as light and strong as possible, what is the best material to use?

Really, the "what is the best material for a gear?" question has no better answer than "It depends." All else being the same, stronger and lighter is better, but we also have to consider factors such as cost, expected lifetime, lubrication requirements, sound properties, acceptable backlash, ...

Unless Nylon or polymer gears are saturated with the right type of oil they will absorb water and other oil components which makes them swell by several percent during use.Nugatory said:But nylon timing gears were once quite common, before the widespread adoption of timing chains.
The best material for making gears depends on the specific application and requirements. Some commonly used materials for gears include steel, cast iron, brass, and plastic. Each material has its own unique properties and advantages.
The key factors to consider when choosing a material for gears include the load and speed requirements, the environment in which the gears will operate, and the cost and availability of the material. It is important to select a material that can withstand the forces and conditions it will be subjected to.
Steel is a commonly used material for gears because it is strong, durable, and can withstand high loads and speeds. It is also readily available and cost-effective. Additionally, steel can be heat-treated to increase its hardness and wear resistance, making it suitable for a wide range of gear applications.
Plastic gears have several advantages, including being lightweight, corrosion-resistant, and quieter than metal gears. They also have the ability to absorb shock and vibration, making them suitable for use in precision equipment. However, they may not be suitable for high-load or high-speed applications.
Yes, there is ongoing research and development in the field of gear materials. Some new materials being explored for gear applications include composites, ceramics, and advanced plastics. These materials offer unique properties such as increased strength, wear resistance, and reduced weight. However, further testing and development are needed before they can be widely used in gear manufacturing.
