Medical technology requires instruments with precise motorised drives for safe and quiet operation around people. In addition to precise positioning within a tolerance of millimetres Nabtesco Vigo Drive RV-N and RH-N cycloidal gears and gear heads are also designed with a high margin of safety to prevent injuries to patients and staff in the event of a disruption. "We deliver custom and integrated precision gears that more than fulfil the high standards of medical technology," says Marcus Löw, Sales Director at Nabtesco Precision Europe.
Compact and high-performance eccentric gears
Nabtesco gears are designed for a long life and stable operation, with an emergency stop torque of up to 5 times the rated torque. In addition, their overload capacity allows them to move heavy loads easily. To minimise the noise level in the vicinity of the patient the reduction gears are available in a low-noise version.
Despite the compact design, these cycloidal gears are extremely powerful due to their reinforced eccentric shaft bearing. Their low weight provides for low mass inertia and improved load conditions. A special heat treatment process makes the reduction gears extremely temperature-resistant and durable. The high rigidity and low backlash of less than one angular minute allow precise and smooth positioning.
