DORST Technologies and Alvier PM Technology: Advancing Gear Manufacturing with E-Powered Pressing Systems SVZe for Helical Gears

In the realm of PM gear manufacturing, the adoption of advanced technologies has revolutionised production processes, enhancing efficiency, precision, and overall quality. One such innovation is the e-powered pressing system, specifically designed for pressing helical gears. This technical article explores the role of DORST Technologies and Alvier PM Technology, leading companies in the field, in advancing gear pressing through their state-of-the-art e-powered pressing systems. Helical gear systems are widely used in various industries, offering superior performance and efficiency compared to other gear types. With their unique design and capabilities, helical gears play a critical role in power transmission, allowing for smooth and precise rotational motion.

Helical gears offer several advantages that make them popular in numerous applications
Increased load-carrying capacity: The inclined teeth of helical gears allow for multiple teeth to be in contact simultaneously, distributing the load more evenly. This enhanced tooth engagement results in higher torque transmission capabilities. Smooth and quiet operation: The gradual tooth engagement of helical gears reduces noise and vibration compared to other gear types, such as spur gears. This characteristic makes helical gears ideal for applications where low noise levels are critical, such as automotive transmissions in combustion engines, but also in EV vehicles. Efficiency and reduced backlash: The helical tooth geometry enables a larger contact area, resulting in improved power transmission efficiency. Additionally, the inclined teeth minimise backlash, enhancing the accuracy and repeatability of motion control systems. Smooth running and porosity: Helical gears produced with the PM process (press and sinter) create higher surface porosity and enables a smooth running in use. 

Extensive use across numerous industries and applications
Automotive industry: Helical gears are commonly employed in vehicle transmissions, providing smooth and efficient power transfer between the engine and wheels. Industrial machinery: They are widely used in various industrial applications, such as pumps, compressors, conveyors, and machine tools, where high torque and precise motion control are essential. Power generation: Helical gears play a crucial role in power generation equipment, including wind turbines, hydroelectric generators, and steam turbines. Robotics and automation: The precision and efficiency of helical gears make them indispensable in robotics, enabling accurate and reliable motion control in robotic systems.
