Precision cycloidal gears make the difference
Nabtesco says it is perfectly possible to optimise costs and simultaneously boost performance in the production environment. Its gear systems are extremely precise, very robust and absolutely reliable, which significantly optimises costs and boosts performance in the production industry.
The production industry faces major challenges, not least immense cost pressure, ever-increasing customer requirements, stronger competition. But how can one optimise production? And which strategies result in significant increases in production and reduced costs?
There are numerous potential areas for optimisation. It is always worthwhile to have a look at the production systems. Gears transmit and convert torques, speeds and directions of rotation, as well as forces, and therefore define the speed or cycle time. If they do not operate with the required precision, speed and reliability, this will affect the performance of the machine or system accordingly.
Precision cycloidal gears are one example of an especially high-performance technology. Their special design makes them much more precise, dynamic and rigid than the commonly used rotary indexers and standard planetary gears - which makes it possible to achieve substantial improvements in efficiency. Users benefit from faster machining processes, shorter cycle times, higher productivity, outstanding product quality, and lower costs.
For more than 35 years, Nabtesco has been implementing innovative, efficient drive solutions for automation and robotics. The gear specialist pursues a consistent design-to-cost method, in addition to the simplicity principle for reducing complexity within the overall system. That is a guarantee for maximum performance, efficiency, user convenience, and process reliability.
Nabtesco has the most extensive and most diverse range of precision gear products on the market. The series that are particularly suitable for automation in small and mid-sized enterprises include Neco and Neco HT (modular plug and play gearboxes with a solid shaft), RD-C (versatile hollow-shaft gearboxes) and RS (powerful rotary indexers). The ready-to-use solutions are designed for fast and easy integration in the machine drive train, as well as intuitive operation.
Precision gears with high power density
Cycloidal gears use cams and rollers for power transmission. This ensures high efficiency, exceptional resistance to shock loads (up to 500% of the rated torque) and minimal backlash throughout the entire service life (maximum hysteresis loss of 1 arcmin). The purely mechanical backlash is as low as 0.1-0.2 arcmin. A precision planetary gear, by comparison, has purely mechanical backlash of 1-3 arcmin.
Thanks to their two-stage reduction principle, precision cycloidal gears achieve excellent performance with respect to dynamics and smooth operation, as well as excellent repeat and path accuracy. They perform flawlessly even in high-precision positioning applications with heavy loads or very fast and abrupt motions.
