Planetary traction drive unit

Basic information

• Realization of low noise, low vibration and rotational accuracy that break through the boundary of gears.
• Mitsubishi is a top runner in the traction drive technology.
• Our products are highly reputed in the fields of cutting-edge technologies, including the digital image processors, ultra-precision machine tools, film manufacturing and coating equipment.
• Mitsubishi is sole supplier of traction drives that enable larger torque transmissions. (Max. 6,000 Nm)

High rotational accuracy (Minimum speed irregularity)

• Planetary mechanism composed of rollers produces smooth rotations and eliminates the speed irregularity due to the high frequency inherent to gear transmissions.

Zero backlash, ultra-precision positioning accuracy

• Transmission by rollers being contacted under pressure allows to eliminate the backlash so that ultra-precision positioning can be achieved in the full closed loop controls.

Low noise/low vibration

• Since the movement is produced by the rotation of rollers, it produces a capacity that breaks through the boundary of gear transmissions.
