Cycloidal gears: No. 1 for handling and positioning

Cycloidal gears are the best solution for applications related to with precise and dynamic movement and positioning. Their high precision and power density allow you to improve product quality, increase productivity and reduce costs. They are an effective alternative to conventional technologies such as planetary gears and direct drives.

Nabtesco is the world's largest manufacturer of precision cycloidal gears and a leader in the robotics market, making it a highly sought after automation partner. Whether gearboxes are used in robotics, machine and plant construction, electric vehicles, logistics or medical technology: Innovative gearbox systems are widespread in all industries and represent an important factor in reducing costs and increasing efficiency.

Innovative, extremely efficient technology

Cycloidal gears use eccentrics and rollers to transmit power. This ensures high accuracy, exceptional resistance to shock loads (up to 500% of the rated torque) and minimal backlash over the lifetime (0.5 to 1 arcmin hysteresis loss). Thanks to the two-stage reduction principle, the precision gears also achieve excellent parameters in terms of dynamics and smoothness of work, as well as high repeatability and precision of movement. Gears work impeccably even in the case of high-precision positioning applications with heavy loads or very fast and rapid movements.

A cost-effective alternative to low-backlash planetary gears

Where precision and positioning accuracy are important, cycloidal gears offer consistently better performance characteristics compared to planetary gears. Because they have a more robust construction, they're also more durable. Even over longer periods, the increase in backlash is very small with the cycloidal gearbox - a decisive advantage over economical planetary gearboxes, which often experience increased backlash during operation. Cycloidal gears are stiffer and more compact (about 50% shorter) and lighter than multi-stage planetary gears. In addition, their ability to withstand overloads is five times higher.

Integrated main bearing: The gearbox as a load-bearing component of the machine

Thanks to the solid, integrated main bearing Nabtesco gears also withstand 250% higher bending moments than conventional planetary gears of comparable size. In this way, they become a load-bearing element of the machine or robot and do not require external bearings. Users benefit from improved performance, more compact design, less engineering, faster installation and reduced costs.

More efficient, durable and more economical than direct drives

Cycloidal gears also offer decisive advantages over direct drives. Direct drives are widely used in machine tool manufacturing systems. However, they consume a lot of energy and must be cooled with water when rotating components with high moments of inertia. Also with regard to issues such as CO2 footprint, energy efficiency, total assembly and cost optimization, the limitations of gearless drives quickly become obvious. Nabtesco cycloidal gearboxes are a much more attractive choice for many applications, both technologically and economically. Not only are they cheaper and easier to install, they also reduce energy consumption and require less installation space.
