Nabtesco is presenting further, particularly compact variants of its shaft gearboxes, especially for humanoid robots and cobots.

The gearbox manufacturer Nabtesco is adding particularly compact variants to its product range of shaft gearboxes. They transmit up to 120 percent of the torque of conventional gearboxes. They also have around one and a half times the service life. The currently presented shaft gearboxes in short design are 65 percent shorter than standard versions. They are therefore ideal for compact joints, for example in exoskeletons, humanoid robots and cobots.

Significant Icrease in Performance

The so-called short gears from Nabtesco transmit 20 percentage points higher nominal torques with the same dimensions compared to classic shaft gears. The same applies to repeatable peak torques, acceleration and limit torques for emergency stop, ratcheting, buckling and collision.

High Rated Torques

The short gearboxes are available in variants for 4.5 to 115 Nm nominal torque. They can be realized either as top-hat or pot gearboxes. They have a hollow shaft and offer sufficient space to route supply lines, cables and hoses through the inside of the gearbox. The shaft gearboxes can also be individually designed and their performance, geometry, material and interfaces can be precisely tailored to the respective application, including function, component and system integration if required. They are manufactured at Ovalo GmbH in Limburg (Lahn, Germany) in accordance with the automotive standard (IATF certification 16949).

Ideal for Robotics

The manufacturer sees key applications in wearables (exoskeletons) and robot joints for humanoid robots and cobots. The short shaft gears can also be used in medical technology systems such as surgical robots and dental milling machines as well as detector and optics adjustments in imaging systems. They can also prove advantageous for industrial robots, positioning and rotary axes, machine tools and in watch manufacturing systems.
