Are you among those who primarily associate safety with software, sensors and control electronics? Then you should definitely keep reading. Because the topic of security is much more complex than it seems at first glance. The hardware is equally crucial for the safe operation of machines, systems and robots. The key role in this regard is played by the gear units. But, why is that and what is it that makes gear units safe?
Safety: Gear units and functional reliability
Gears transmit and convert torques, rotational speeds and directions, as well as forces, which makes them a central element in the power train of machines, systems and robots. If they fail to perform in a safe and reliable manner, dire consequences may ensue – from unscheduled downtimes to harm to human beings and equipment. Which means: Only if the gears or mechanical drive technology have/has met the demanding requirements of the application can the highest level of safety, functional reliability and process stability be achieved.
Factors that contribute to the safety of the gears:
Nabtesco gears are safety fanatics through and through
Holding the rank of the world’s largest and most highly acclaimed manufacturer of precision cycloidal gears and of market leader in the field of robotic gears (market share of more than 60%), Nabtesco is highly familiar with the vast challenges that threaten the safety of products, processes and machines and realises innovative drive solutions with a maximum level of quality, availability, and reliability.
The innovative gear systems have been used a million times over in robotics & automation and have proven themselves successfully in countless applications. They feature high dynamics and precision (max. hysteresis loss of 0.5 to 1 arcmin), minimal wear throughout the service life, outstanding shock resistance (up to 500 % of the rated torque; optionally, up to 800 %), and a high overload capacity (two to three times higher than that of planetary gears). Precision cycloidal gears are ideally suited to reduce risks to a minimum. Ensuring functional reliability paired with a maximum degree of machine and system safety, they form the basis for processes in the manufacturing industry that deliver high performance and are reliable and smooth.
Quality provider, global player, large-scale manufacturer, and safety expert
Worldwide, well over twelve million Nabtesco gear units are in use - with a strongly upward tendency. The number of gear units manufactured each year exceeds one million. The construction of a third production site in Hamamatsu (Japan) will double the company’s production output to two million precision gears by 2030 – an ideal scenario to meet the surging demand for automation solutions. The highly automated production process, which is based on Japanese principles such as poka-yoke (fail-safing) and kaizen (continuous improvement), is oriented toward maximum efficiency and consistently high quality. Prior to delivery, the gears are subjected to a 100% inspection: Each individual gear unit is put through its paces.
Employing a staff of 8,000 worldwide, Nabtesco is part of the Nabtesco Corporation and can utilise a global distributor network, allowing the company to provide fast service and competent advice on site. Another contributing factor to safety.
