It's a custom product, which means you can't buy it directly. Of course, we also have generic types of products. You can check out our fast product delivery categories.
Product Description
Desigh Tips:
1. Radius > 0.25 mm is required to manufacture the die;
2. Helical teeth should feature a helical angle < 30º in order to limit side pressure on the punches;
3. Introduction of a draft angle > 5º in the upper diameter reduce the tooling cost;
4. The distance between tooth root and central hub diameter must be: > 3 mm (Robust Tooling).

Powder metallurgy process
Characteristics of Powder Metallurgy Gears
Powder metallurgy (PM) is a versatile manufacturing process that involves the production of components from powdered metal. Gears manufactured using this process, known as powder metallurgy gears, possess several unique characteristics that make them highly desirable in various industries. In this article, we will explore some of the key features and advantages of powder metallurgy gears.
1. Cost-effective production: Powder metallurgy gears offer significant cost advantages compared to gears produced through traditional methods such as forging or machining. The PM process allows for a high material utilization rate, reducing wastage and minimizing production costs. Additionally, the elimination of expensive machining operations results in lower labor and tooling costs, making powder metallurgy gears an economical choice for gear manufacturers.
2. Design flexibility: Powder metallurgy gears provide excellent design flexibility, allowing for the production of complex gear geometries that are difficult to achieve using conventional manufacturing techniques. The PM process enables the production of gears with intricate shapes, including internal and external splines, helical gears, and bevel gears. This flexibility in design allows gear manufacturers to meet specific application requirements and optimize gear performance.
3. Enhanced material properties: Powder metallurgy gears exhibit superior material properties compared to gears made using conventional methods. The PM process allows for the use of a wide range of alloy compositions, including low-alloy steels, stainless steels, and non-ferrous materials such as bronze and brass. By carefully selecting the alloy composition and controlling the powder metallurgy process parameters, gear manufacturers can achieve desired mechanical properties such as high strength, wear resistance, and fatigue resistance.
4. Improved dimensional accuracy: Powder metallurgy gears offer excellent dimensional accuracy and tight tolerances. The PM process involves pressing metal powders into a die cavity, followed by sintering at high temperatures. This sintering process results in a net-shape or near-net-shape component, minimizing the need for secondary machining operations. The ability to produce gears with precise dimensions ensures proper meshing and alignment, leading to improved gear performance and reduced noise levels.
5. Enhanced surface finish: Powder metallurgy gears typically have a smooth surface finish, eliminating the need for additional finishing operations such as grinding or polishing. The sintering process helps to consolidate the metal powders, resulting in a dense and uniform structure. This uniformity contributes to improved gear surface quality, reduced friction, and enhanced gear efficiency.
6. Reduced material waste: The powder metallurgy process minimizes material waste compared to traditional manufacturing methods. The ability to accurately control the powder composition and shape during the pressing stage ensures efficient material utilization. Additionally, any excess powder generated during the pressing process can be recycled, further reducing material waste and contributing to a more sustainable manufacturing process.
7. Consistent quality: Powder metallurgy gears offer consistent and reliable quality. The PM process allows for precise control over the production parameters, ensuring consistent material properties and gear performance. This consistency is crucial for applications that require high precision and reliability, such as automotive transmissions, industrial machinery, and aerospace systems.
In conclusion, powder metallurgy gears possess several distinct characteristics that make them highly advantageous in various industries. Their cost-effectiveness, design flexibility, enhanced material properties, improved dimensional accuracy, enhanced surface finish, reduced material waste, and consistent quality make them a preferred choice for gear manufacturers. As technology continues to advance, powder metallurgy gears are likely to play an increasingly significant role in the production of high-performance gears.
